Subject: media: rc: self test for IR encoders and decoders

ir-loopback can transmit IR on one rc device and check the correct
scancode and protocol is decoded on a different rc device. This can be
used to check IR transmission between two rc devices. Using rc-loopback,
we use it to check the IR encoders and decoders themselves.

No hardware is required for this test.

From f96afa767baffba7645f5e10998f5178948bb9aa Mon Sep 17 00:00:00 2001
From: Quentin Monnet <quentin.monnet@netronome.com>
Date: Wed, 7 Nov 2018 12:28:45 +0000
Subject: selftests/bpf: enable (uncomment) all tests in test_libbpf.sh

libbpf is now able to load successfully test_l4lb_noinline.o and
samples/bpf/tracex3_kern.o.

For the test_l4lb_noinline, uncomment related tests from test_libbpf.c
and remove the associated "TODO".

For tracex3_kern.o, instead of loading a program from samples/bpf/ that
might not have been compiled at this stage, try loading a program from
BPF selftests. Since this test case is about loading a program compiled
without the "-target bpf" flag, change the Makefile to compile one
program accordingly (instead of passing the flag for compiling all
programs).

Regarding test_xdp_noinline.o: in its current shape the program fails to
load because it provides no version section, but the loader needs one.
The test was added to make sure that libbpf could load XDP programs even
if they do not provide a version number in a dedicated section. But
libbpf is already capable of doing that: in our case loading fails
because the loader does not know that this is an XDP program (it does
not need to, since it does not attach the program). So trying to load
test_xdp_noinline.o does not bring much here: just delete this subtest.

For the record, the error message obtained with tracex3_kern.o was
fixed by commit e3d91b0ca523 ("tools/libbpf: handle issues with bpf ELF
objects containing .eh_frames")

I have not been abled to reproduce the "libbpf: incorrect bpf_call
opcode" error for test_l4lb_noinline.o, even with the version of libbpf
present at the time when test_libbpf.sh and test_libbpf_open.c were
created.

RFC -> v1:
- Compile test_xdp without the "-target bpf" flag, and try to load it
  instead of ../../samples/bpf/tracex3_kern.o.
- Delete test_xdp_noinline.o subtest.

Subject: selftests: add dummy xdp test helper

This trivial XDP program does nothing, but will be used by the
next patch to test the GRO path in a net namespace, leveraging
the veth XDP implementation.

It's added here, despite its 'net' usage, to avoid the duplication
of the llc-related makefile boilerplate.

rfc v3 -> v1:
 - move the helper implementation into the bpf directory, don't
   touch udpgso_bench_rx

rfc v2 -> rfc v3:
 - move 'x' option handling here

Subject: selftests: add functionals test for UDP GRO

Extends the existing udp programs to allow checking for proper
GRO aggregation/GSO size, and run the tests via a shell script, using
a veth pair with XDP program attached to trigger the GRO code path.

rfc v3 -> v1:
 - use ip route to attach the xdp helper to the veth

rfc v2 -> rfc v3:
 - add missing test program options documentation
 - fix sporatic test failures (receiver faster than sender)

Subject: selftests: pmtu: Introduce FoU and GUE PMTU exceptions tests

Introduce eight tests, for FoU and GUE, with IPv4 and IPv6 payload,
on IPv4 and IPv6 transport, that check that PMTU exceptions are created
with the right value when exceeding the MTU on a link of the path.

Subject: rcutorture: Automatically create initrd directory

The rcutorture scripts currently expect the user to create the
tools/testing/selftests/rcutorture/initrd directory.  Should the user
fail to do this, the kernel build will fail with obscure and confusing
error messages.  This commit therefore adds explicit checks for the
tools/testing/selftests/rcutorture/initrd directory, and if not present,
creates one on systems on which dracut is installed.  If this directory
could not be created, a less obscure error message is emitted and the
test is aborted.

Subject: rcutorture: Add initrd support for systems lacking dracut

The support for creating initrd directories using dracut is a great
improvement over having to always hand-create them, it is a bit annoying
to have to install some otherwise irrelevant package just to be able to
run rcutorture.  This commit therefore adds support for creating initrd
directories on systems innocent of dracut.  You do need gcc, but then
again you need that to build the kernel (or to build llvm) in any case.

The idea is to create an initrd directory containing nothing but a
statically linked binary having a for-loop over a long-term sleep().
The result is a Linux kernel with almost no userspace: even the
time-honored /dev, /lib, /tmp, and /usr directories are gone.  In fact,
the only directory present is "/", but only because I don't know how to
get rid of it, at least short of not having an initrd in the first place.
Although statically linked binaries are much maligned, and rightly so,
their disadvantages seem to be irrelevant for this particular use case.
From https://www.akkadia.org/drepper/no_static_linking.html:

1.	Fixes are difficult to apply to hordes of widely scattered
	statically linked binaries.  But in this case, there is only one
	binary, but there would otherwise be no fewer than four libraries.

2.	Security measures like local address randomization cannot be used.
	Prudence prevents me from asserting that it is impossible to
	base a remote attack on a networking-free rcutorture instance.
	Nevertheless, bonus points to the first person who comes up with
	such an attack!

3.	More efficient use of physical memory.  Not in this case, given
	that libc is 1.8MB and the statically linked binary "only" 800K.

4.	Features such as locales, name service switch (NSS),
	internationalized domain names (IDN) tool, and so on require
	dynamic linking.  Bonus points to the first person coming up
	with a valid rcutorture use case requiring these features in
	its initrd.

5.	Accidental violations of (L)GPL.  Actually, this change actually
	helps -avoid- such violations by reducing the temptation to
	pass around tarballs of rcutorture-ready initrd directories.
	After all, the rcutorture scripts automatically create an initrd
	directory for you, so why bother with the tarballs?

6.	Tools and hacks like ltrace, LD_PRELOAD, LD_PROFILE, and LD_AUDIT
	don't work.  Again, bonus points to the first person coming up
	with a valid rcutorture use case requiring these features in
	its initrd.

Nevertheless, the script will use dracut if available, and will create the
statically linked binary only when dracut are missing.  Those preferring
the smaller initrd directory resulting from the statically linked binary
(like me) are free to hand-edit mkinitrd.sh to remove the code using
dracut.  ;-)

Subject: rcutorture: Make initrd/init execute in userspace

Currently, the initrd/init script and executable remain blocked almost
all the time.  However, it is necessary to test nohz_full userspace
execution, which both variants of initrd/init fail to do.  This commit
therefore causes initrd/init to spend about a millisecond per second
executing in userspace.

Subject: rcutorture: Check initrd/init instead of initrd only

If the build fails, we can end up with an empty initrd directory which
prevents the build script from operating again. Better rely on the
resulting init executable instead.

This is a definition of the most common syscalls needed in minimalist
init executables, allowing to statically build them with no external
dependencies. It is sufficient in its current form to build rcutorture's
init on x86_64, i386, arm, and arm64. Others have not been ported or
tested. Updates may be found here :

+ *   - syscall number is passed in v0 (starts at 0xfa0).

+ *     preserved. See: https://www.linux-mips.org/wiki/Syscall as well as
+ *     scall32-o32.S in the kernel sources.
+ *   - the system call is performed by calling "syscall"
+ *   - syscall return comes in v0, and register a3 needs to be checked to know
+ *     if an error occured, in which case errno is in v0.
+ *   - the arguments are cast to long and assigned into the target registers

Subject: rcutorture: Make use of nolibc when available

This reduces the size of the init executable from ~800 kB to ~800 bytes
on x86_64. This is only implemented for x86_64, i386, arm and arm64.
Others not tested.

From: Sowmini Varadhan <sowmini.varadhan@oracle.com>
Date: Wed, 7 Nov 2018 16:12:02 -0800
Subject: selftests/bpf: add a test case for sock_ops perf-event notification

This patch provides a tcp_bpf based eBPF sample. The test

- ncat(1) as the TCP client program to connect() to a port
  with the intention of triggerring SYN retransmissions: we
  first install an iptables DROP rule to make sure ncat SYNs are
  resent (instead of aborting instantly after a TCP RST)

- has a bpf kernel module that sends a perf-event notification for
  each TCP retransmit, and also tracks the number of such notifications
  sent in the global_map

The test passes when the number of event notifications intercepted
in user-space matches the value in the global_map.

From b69d540da7db84e836cea77fbd56a518aafa1f2f Mon Sep 17 00:00:00 2001
From: Florian Westphal <fw@strlen.de>
Date: Wed, 7 Nov 2018 23:00:31 +0100
Subject: selftests: add xfrm policy test script

add a script that adds a ipsec tunnel between two network
namespaces plus following policies:

.0/24 -> ipsec tunnel
.240/28 -> bypass
.253/32 -> ipsec tunnel

Then check that .254 bypasses tunnel (match /28 exception),
and .2 (match /24) and .253 (match direct policy) pass through the
tunnel.

Abuses iptables to check if ping did resolve an ipsec policy or not.

Also adds a bunch of 'block' rules that are not supposed to match.

Subject: selftests/bpf: rename flow dissector section to flow_dissector

Makes it compatible with the logic that derives program type
from section name in libbpf_prog_type_by_name.

Subject: xfrm: policy: fix netlink/pf_key policy lookups

Colin Ian King says:
 Static analysis with CoverityScan found a potential issue [..]
 It seems that pointer pol is set to NULL and then a check to see if it
 is non-null is used to set pol to tmp; howeverm this check is always
 going to be false because pol is always NULL.

Fix this and update test script to catch this.  Updated script only:
./xfrm_policy.sh ; echo $?
RTNETLINK answers: No such file or directory
FAIL: ip -net ns3 xfrm policy get src 10.0.1.0/24 dst 10.0.2.0/24 dir out
RTNETLINK answers: No such file or directory
[..]
PASS: policy before exception matches
PASS: ping to .254 bypassed ipsec tunnel
PASS: direct policy matches
PASS: policy matches
1

Subject: selftest/bpf: Use bpf_sk_lookup_{tcp, udp} in test_sock_addr

Use bpf_sk_lookup_tcp, bpf_sk_lookup_udp and bpf_sk_release helpers from
test_sock_addr programs to make sure they're available and can lookup
and release socket properly for IPv4/IPv4, TCP/UDP.

Reading from a few fields of returned struct bpf_sock is also tested.

Subject: selftests: forwarding: lib: Support NUM_NETIFS of 0

So far the case of NUM_NETIFS of 0 has not been interesting. However if
one wishes to reuse the lib.sh routines in a setup of a separate
namespace, being able to import like this is handy.

Therefore replace the {1..$NUM_NETIFS} references, which cause iteration
over 1 and 0, with an explicit for loop like we do in setup_wait() and
tc_offload_check(), so that for NUM_NETIFS of 0 no iteration is done.

Subject: selftests: forwarding: lib: Add in_ns()

In order to run a certain command inside another network namespace, it's
possible to use "ip netns exec ns command". However then one can't use
functions defined in lib.sh or a test suite.

One option is to do "ip netns exec ns bash -c command", provided that
all functions that one wishes to use (and their dependencies) are
published using "export -f". That may not be practical.

Therefore, introduce a helper in_ns(), which wraps a given command in a
boilerplate of "ip netns exec" and "source lib.sh", thus making all
library functions available. (Custom functions that a script wishes to
run within a namespace still need to be exported.)

Because quotes in "$@" aren't recognized in heredoc, hand-expand the
array in an explicit for loop, leveraging printf %q to handle proper
quoting.

Subject: selftests: forwarding: ping{6, }_test(): Add description argument

Have ping_test() recognize an optional argument with a description of
the test. This is handy if there are several ping test, to make it clear
which is which.

Subject: selftests: forwarding: lib: Add link_stats_rx_errors_get()

Such a function will be useful for counting malformed packets in the ECN
decap test.

To that end, introduce a common handler for handling stat-fetching, and
reuse it in link_stats_tx_packets_get() and link_stats_rx_errors_get().

Date: Mon, 19 Nov 2018 16:11:14 +0000
Subject: selftests: forwarding: Add a skeleton of vxlan_bridge_1d

This skeleton sets up a topology with three VXLAN endpoints: one
"local", possibly offloaded, and two "remote", formed using veth pairs
and likely purely software bridges. The "local" endpoint is connected to
host systems by a VLAN-unaware bridge.

Since VXLAN tunnels must be unique per namespace, each of the "remote"
endpoints is in its own namespace. H3 forms the bridge between the three
domains.

Subject: selftests: forwarding: vxlan_bridge_1d: Add ping test

Test end-to-end reachability between local and remote endpoints.

Note that because learning is disabled on the VXLAN device, the ICMP
requests will end up being flooded to all remotes.

Subject: selftests: forwarding: vxlan_bridge_1d: Reconfigure & rerun tests

The ordering of the topology creation can have impact on whether a
driver is successful in offloading VXLAN. Therefore add a pseudo-test
that reshuffles bits of the topology, and then reruns the same suite of
tests again to make sure that the new setup is supported as well.

Test that when decapsulating from VXLAN, the values of inner and outer

produce the arbitrary TOS combinations necessary to test this feature,
simply open-code a single ICMP packet and have mausezahn assemble it.

Subject: selftests: mlxsw: Add a test for VxLAN flooding

The device stores flood records in a singly linked list where each
record stores up to three IPv4 addresses of remote VTEPs. The test
verifies that packets are correctly flooded in various cases such as
deletion of a record in the middle of the list.

Subject: tools/bpf: extends test_btf to test load/retrieve func_type info

A two function bpf program is loaded with btf and func_info.
After successful prog load, the bpf_get_info syscall is called
to retrieve prog info to ensure the types returned from the
kernel matches the types passed to the kernel from the
user space.

Several negative tests are also added to test loading/retriving
of func_type info.

Subject: tools/bpf: enhance test_btf file testing to test func info

Change the bpf programs test_btf_haskv.c and test_btf_nokv.c to
have two sections, and enhance test_btf.c test_file feature
to test btf func_info returned by the kernel.

The test currently expects that a configuration which includes a VxLAN
device with learning enabled to fail.

Previous patches enabled VxLAN learning in mlxsw, so change the test
accordingly.

Subject: selftests: explicitly require kernel features needed by udpgro tests

commit 3327a9c46352f1 ("selftests: add functionals test for UDP GRO")
make use of ipv6 NAT, but such a feature is not currently implied by
selftests. Since the 'ip[6]tables' commands may actually create nft rules,
depending on the specific user-space version, let's pull both NF and
NFT nat modules plus the needed deps.

Subject: bpf: add skb->tstamp r/w access from tc clsact and cg skb progs

This could be used to rate limit egress traffic in concert with a qdisc
which supports Earliest Departure Time, such as FQ.

Write access from cg skb progs only with CAP_SYS_ADMIN, since the value
will be used by downstream qdiscs. It might make sense to relax this.

Changes v1 -> v2:
  - allow access from cg skb, write only with CAP_SYS_ADMIN

Subject: selftests/net: add txring_overwrite

Packet sockets with PACKET_TX_RING send skbs with user data in frags.

Before commit 5cd8d46ea156 ("packet: copy user buffers before orphan
or clone") ring slots could be released prematurely, possibly allowing
a process to overwrite data still in flight.

This test opens two packet sockets, one to send and one to read.
The sender has a tx ring of one slot. It sends two packets with
different payload, then reads both and verifies their payload.

Before the above commit, both receive calls return the same data as
the send calls use the same buffer. From the commit, the clone
needed for looping onto a packet socket triggers an skb_copy_ubufs
to create a private copy. The separate sends each arrive correctly.

Subject: selftests/powerpc: Allocate base registers

Some ptrace selftests are passing input operands using a constraint that
can allocate any register for the operand, and using these registers on
load/store operations.

If the register allocated by the compiler happens to be zero (r0), it might
cause an invalid memory address access, since load and store operations
consider the content of 0x0 address if the base register is r0, instead of
the content of the r0 register. For example:

	r1 := 0xdeadbeef
	r0 := 0xdeadbeef

	ld r2, 0(1) /* will load into r2 the content of r1 address */
	ld r2, 0(0) /* will load into r2 the content of 0x0 */

In order to avoid this possible problem, the inline assembly constraint
should be aware that these registers will be used as a base register, thus,
r0 should not be allocated.

Other than that, this patch removes inline assembly operands that are not
used by the tests.

Subject: selftests/powerpc: Create a new SKIP_IF macro

This patch creates a new macro that skips a test and prints a message to
stderr. This is useful to give an idea why the tests is being skipped,
other than just skipping the test blindly.

Subject: selftests/powerpc: Skip test instead of failing

Current core-pkey selftest fails if the test runs without privileges to
write into the core pattern file (/proc/sys/kernel/core_pattern). This
causes the test to fail and give the impression that the subsystem being
tested is broken, when, in fact, the test is being executed without the
proper privileges. This is the current error:

	test: core_pkey
	tags: git_version:v4.19-3-g9e3363be9bce-dirty
	Error writing to core_pattern file: Permission denied
	failure: core_pkey

This patch simply skips this test if it runs without the proper privileges,
avoiding this undesired failure.

Subject: selftests: firmware: remove use of non-standard diff -Z option

"diff -Z" is used to trim the trailing whitespace when comparing the
loaded firmware file with the source firmware file. However, per the
comment in the source code, -Z should not be necessary. In testing, the
input and output files are identical.

Additionally, -Z is not a standard option and is not available in
environments such as busybox. When -Z is not supported, diff fails with
a usage error, which is suppressed, but then causes read_firmwares() to
exit with a false failure message.

Subject: selftests: gpio: Find libmount with pkg-config if available
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If pkg-config is available, use it to define the CFLAGS and
LDLIBS needed for libmount; else, use the current hard-coded
paths and options.

Using pkg-config is very helpful for cross-compilation
environments, and is sometimes readily available on developer
boxes to ensure we get the right compiler/linker options for
the given package.

Extend the existing VLAN-unaware tests with their VLAN-aware
counterparts. This includes sanitization of invalid configuration and
offload indication on the local route performing decapsulation and the
FDB entries perform encapsulation.

Subject: selftests: forwarding: Add VxLAN test with a VLAN-aware bridge

The test is very similar to its VLAN-unaware counterpart
(vxlan_bridge_1d.sh), but instead of using multiple VLAN-unaware
bridges, a single VLAN-aware bridge is used with multiple VLANs.

From: David Miller <davem@davemloft.net>
Date: Fri, 30 Nov 2018 21:08:14 -0800
Subject: bpf: Add BPF_F_ANY_ALIGNMENT.

Often we want to write tests cases that check things like bad context
offset accesses.  And one way to do this is to use an odd offset on,
for example, a 32-bit load.

This unfortunately triggers the alignment checks first on platforms
that do not set CONFIG_EFFICIENT_UNALIGNED_ACCESS.  So the test
case see the alignment failure rather than what it was testing for.

It is often not completely possible to respect the original intention
of the test, or even test the same exact thing, while solving the
alignment issue.

Another option could have been to check the alignment after the
context and other validations are performed by the verifier, but
that is a non-trivial change to the verifier.

Subject: bpf: Adjust F_NEEDS_EFFICIENT_UNALIGNED_ACCESS handling in
 test_verifier.c

Make it set the flag argument to bpf_verify_program() which will relax
the alignment restrictions.

Now all such test cases will go properly through the verifier even on
inefficient unaligned access architectures.

On inefficient unaligned access architectures do not try to run such
programs, instead mark the test case as passing but annotate the
result similarly to how it is done now in the presence of this flag.

So, we get complete full coverage for all REJECT test cases, and at
least verifier level coverage for ACCEPT test cases.

Subject: bpf: Apply F_NEEDS_EFFICIENT_UNALIGNED_ACCESS to more ACCEPT test
 cases.

If a testcase has alignment problems but is expected to be ACCEPT,
verify it using F_NEEDS_EFFICIENT_UNALIGNED_ACCESS too.

Maybe in the future if we add some architecture specific code to elide
the unaligned memory access warnings during the test, we can execute
these as well.

Subject: rcutorture/formal: Replace synchronize_sched() with synchronize_rcu()

Now that synchronize_rcu() waits for preempt-disable regions of code
as well as RCU read-side critical sections, synchronize_sched() can be
replaced by synchronize_rcu().  This commit therefore makes this change,
even though it is but a comment.

Subject: bpf: allow BPF read access to qdisc pkt_len

The pkt_len field in qdisc_skb_cb stores the skb length as it will
appear on the wire after segmentation. For byte accounting, this value
is more accurate than skb->len. It is computed on entry to the TC
layer, so only valid there.

Allow read access to this field from BPF tc classifier and action
programs. The implementation is analogous to tc_classid, aside from
restricting to read access.

To distinguish it from skb->len and self-describe export as wire_len.

Changes v1->v2
  - Rename pkt_len to wire_len

Subject: test/net: Add script for VXLAN underlay in a VRF

This script tests the support of a VXLAN underlay in a non-default VRF.

It does so by simulating two hypervisors and two VMs, an extended L2
between the VMs with the hypervisors as VTEPs with the underlay in a
VRF, and finally by pinging the two VMs.

It also tests that moving the underlay from a VRF to another works when
down/up the VXLAN interface.

Subject: selftests: extend zerocopy tests to udp

Both msg_zerocopy and udpgso_bench have udp zerocopy variants.
Exercise these as part of the standard kselftest run.

With udp, msg_zerocopy has no control channel. Ensure that the
receiver exits after the sender by accounting for the initial
delay in starting them (in msg_zerocopy.sh).

Subject: selftests: add a test for bpf_prog_test_run_xattr

Make sure that bpf_prog_test_run_xattr returns the correct length
and that the kernel respects the output size hint. Also check
that errno indicates ENOSPC if there is a short output buffer given.

Subject: bpf: Expect !info.func_info and insn_off name changes in
 test_btf/libbpf/bpftool

Similar to info.jited_*, info.func_info could be 0 if
bpf_dump_raw_ok() == false.

This patch makes changes to test_btf and bpftool to expect info.func_info
could be 0.

This patch also makes the needed changes for s/insn_offset/insn_off/.

Date: Fri, 7 Dec 2018 19:55:18 +0000
Subject: selftests: mlxsw: vxlan: Test FDB un/marking on VXLAN join/leave

When a VXLAN device is attached to an offloaded bridge, or when a
front-panel port is attached to a bridge that already has a VXLAN
device, mlxsw should offload the existing offloadable FDB entries.
Similarly when VXLAN device is downed, the FDB entries are unoffloaded,
and the marks thus need to be cleared. Similarly when a front-panel port
device is attached to a bridge with a VXLAN device, or when VLAN flags
are tweaked on a VXLAN port attached to a VLAN-aware bridge.

Test that the replaying / clearing logic works by observing transitions
in presence of offload marks under different scenarios.

Subject: selftests: forwarding: Add PVID test case for VXLAN with VLAN-aware
 bridges

When using VLAN-aware bridges with VXLAN, the VLAN that is mapped to the
VNI of the VXLAN device is that which is configured as "pvid untagged"
on the corresponding bridge port.

When these flags are toggled or when the VLAN is deleted entirely,
remote hosts should not be able to receive packets from the VTEP.

Add a test case for above mentioned scenarios.

Subject: selftests: bpf: update testcases for BPF_ALU | BPF_ARSH

"arsh32 on imm" and "arsh32 on reg" now are accepted. Also added two new
testcases to make sure arsh32 won't be treated as arsh64 during
interpretation or JIT code-gen for which case the high bits will be moved
into low halve that the testcases could catch them.

Subject: tc-testing: Add command timeout feature to tdc

Using an attribute set in the tdc_config.py file, limit the
amount of time tdc will wait for an executed command to
complete and prevent the script from hanging entirely.

This timeout will be applied to all executed commands.

This module includes new classes for tdc to use in keeping track
of test case results, instead of generating and tracking a lengthy
string.

The new module can be extended to support multiple formal
test result formats to be friendlier to automation.

From: Martin KaFai Lau <kafai@fb.com>
Date: Fri, 7 Dec 2018 16:42:27 -0800
Subject: bpf: Refactor and bug fix in test_func_type in test_btf.c

1) bpf_load_program_xattr() is absorbing the EBIG error
   which makes testing this case impossible.  It is replaced
   with a direct syscall(__NR_bpf, BPF_PROG_LOAD,...).
2) The test_func_type() is renamed to test_info_raw() to
   prepare for the new line_info test in the next patch.
3) The bpf_obj_get_info_by_fd() testing for func_info
   is refactored to test_get_finfo().  A new
   test_get_linfo() will be added in the next patch
   for testing line_info purpose.
4) The test->func_info_cnt is checked instead of
   a static value "2".
5) Remove unnecessary "\n" in error message.
6) Adding back info_raw_test_num to the cmd arg such
   that a specific test case can be tested, like
   all other existing tests.

7) Fix a bug in handling expected_prog_load_failure.
   A test could pass even if prog_fd != -1 while
   expected_prog_load_failure is true.
8) The min rec_size check should be < 8 instead of < 4.

Subject: media: bpf: add bpf function to report mouse movement

Some IR remotes have a directional pad or other pointer-like thing that
can be used as a mouse. Make it possible to decode these types of IR
protocols in BPF.

From e434b8cdf788568ba65a0a0fd9f3cb41f3ca1803 Mon Sep 17 00:00:00 2001
From: Jiong Wang <jiong.wang@netronome.com>

Subject: bpf: relax verifier restriction on BPF_MOV | BPF_ALU

Currently, the destination register is marked as unknown for 32-bit
sub-register move (BPF_MOV | BPF_ALU) whenever the source register type is
SCALAR_VALUE.

This is too conservative that some valid cases will be rejected.
Especially, this may turn a constant scalar value into unknown value that
could break some assumptions of verifier.

For example, test_l4lb_noinline.c has the following C code:

    struct real_definition *dst

1:  if (!get_packet_dst(&dst, &pckt, vip_info, is_ipv6))
2:    return TC_ACT_SHOT;
3:
4:  if (dst->flags & F_IPV6) {

get_packet_dst is responsible for initializing "dst" into valid pointer and
return true (1), otherwise return false (0). The compiled instruction
sequence using alu32 will be:

  412: (54) (u32) r7 &= (u32) 1
  413: (bc) (u32) r0 = (u32) r7
  414: (95) exit

insn 413, a BPF_MOV | BPF_ALU, however will turn r0 into unknown value even
r7 contains SCALAR_VALUE 1.

This causes trouble when verifier is walking the code path that hasn't
initialized "dst" inside get_packet_dst, for which case 0 is returned and
we would then expect verifier concluding line 1 in the above C code pass
the "if" check, therefore would skip fall through path starting at line 4.
Now, because r0 returned from callee has became unknown value, so verifier
won't skip analyzing path starting at line 4 and "dst->flags" requires
dereferencing the pointer "dst" which actually hasn't be initialized for
this path.

This patch relaxed the code marking sub-register move destination. For a
SCALAR_VALUE, it is safe to just copy the value from source then truncate
it into 32-bit.

A unit test also included to demonstrate this issue. This test will fail
before this patch.

This relaxation could let verifier skipping more paths for conditional
comparison against immediate. It also let verifier recording a more
accurate/strict value for one register at one state, if this state end up
with going through exit without rejection and it is used for state
comparison later, then it is possible an inaccurate/permissive value is
better. So the real impact on verifier processed insn number is complex.
But in all, without this fix, valid program could be rejected.

>From real benchmarking on kernel selftests and Cilium bpf tests, there is
no impact on processed instruction number when tests ares compiled with
default compilation options. There is slightly improvements when they are
compiled with -mattr=+alu32 after this patch.

Also, test_xdp_noinline/-mattr=+alu32 now passed verification. It is
rejected before this fix.

Insn processed before/after this patch:

NOTE:
  - bpf_lxc.o and bpf_netdev.o compiled by -mattr=+alu32 are rejected by
    verifier due to another issue inside verifier on supporting alu32
    binary.
  - Each cilium bpf program could generate several processed insn number,
    above number is sum of them.

v1->v2:
 - Restrict the change on SCALAR_VALUE.
 - Update benchmark numbers on Cilium bpf tests.

Subject: selftests: do not macro-expand failed assertion expressions

I've stumbled over the current macro-expand behaviour of the test
harness:

$ gcc -Wall -xc - <<'__EOF__'
TEST(macro) {
	int status = 0;
	ASSERT_TRUE(WIFSIGNALED(status));
}
TEST_HARNESS_MAIN
__EOF__
$ ./a.out
[==========] Running 1 tests from 1 test cases.
[ RUN      ] global.macro
<stdin>:4:global.macro:Expected 0 (0) != (((signed char) (((status) & 0x7f) + 1) >> 1) > 0) (0)
global.macro: Test terminated by assertion
[     FAIL ] global.macro
[==========] 0 / 1 tests passed.
[  FAILED  ]

With this change the output of the same test looks much more
comprehensible:

[==========] Running 1 tests from 1 test cases.
[ RUN      ] global.macro
<stdin>:4:global.macro:Expected 0 (0) != WIFSIGNALED(status) (0)
global.macro: Test terminated by assertion
[     FAIL ] global.macro
[==========] 0 / 1 tests passed.
[  FAILED  ]

The issue is very similar to the bug fixed in glibc assert(3)
three years ago:

Subject: tools/bpf: rename *_info_cnt to nr_*_info

Rename all occurances of *_info_cnt field access
to nr_*_info in tools directory.

The local variables finfo_cnt, linfo_cnt and jited_linfo_cnt
in function do_dump() of tools/bpf/bpftool/prog.c are also
changed to nr_finfo, nr_linfo and nr_jited_linfo to
keep naming convention consistent.

Subject: selftests/ima: kexec_load syscall test

The kernel CONFIG_KEXEC_VERIFY_SIG option is limited to verifying a
kernel image's signature, when loaded via the kexec_file_load syscall.
There is no method for verifying a kernel image's signature loaded
via the kexec_load syscall.

This test verifies loading the kernel image via the kexec_load syscall
fails when the kernel CONFIG_KEXEC_VERIFY_SIG option is enabled on
systems with secureboot enabled[1].

[1] Detecting secureboot enabled is architecture specific.

Subject: seccomp: add a return code to trap to userspace

This patch introduces a means for syscalls matched in seccomp to notify
some other task that a particular filter has been triggered.

The motivation for this is primarily for use with containers. For example,
if a container does an init_module(), we obviously don't want to load this
untrusted code, which may be compiled for the wrong version of the kernel
anyway. Instead, we could parse the module image, figure out which module
the container is trying to load and load it on the host.

As another example, containers cannot mount() in general since various
filesystems assume a trusted image. However, if an orchestrator knows that
e.g. a particular block device has not been exposed to a container for
writing, it want to allow the container to mount that block device (that
is, handle the mount for it).

This patch adds functionality that is already possible via at least two
other means that I know about, both of which involve ptrace(): first, one
could ptrace attach, and then iterate through syscalls via PTRACE_SYSCALL.
Unfortunately this is slow, so a faster version would be to install a
filter that does SECCOMP_RET_TRACE, which triggers a PTRACE_EVENT_SECCOMP.
Since ptrace allows only one tracer, if the container runtime is that
tracer, users inside the container (or outside) trying to debug it will not
be able to use ptrace, which is annoying. It also means that older
distributions based on Upstart cannot boot inside containers using ptrace,
since upstart itself uses ptrace to monitor services while starting.

The actual implementation of this is fairly small, although getting the
synchronization right was/is slightly complex.

Finally, it's worth noting that the classic seccomp TOCTOU of reading
memory data from the task still applies here, but can be avoided with
careful design of the userspace handler: if the userspace handler reads all
of the task memory that is necessary before applying its security policy,
the tracee's subsequent memory edits will not be read by the tracer.

 and a more generic example of a higher level macro interface for BPF
 program generation.
 
+Userspace Notification
+======================
+
+The ``SECCOMP_RET_USER_NOTIF`` return code lets seccomp filters pass a
+particular syscall to userspace to be handled. This may be useful for
+applications like container managers, which wish to intercept particular
+syscalls (``mount()``, ``finit_module()``, etc.) and change their behavior.
+
+To acquire a notification FD, use the ``SECCOMP_FILTER_FLAG_NEW_LISTENER``
+argument to the ``seccomp()`` syscall:
+
+.. code-block:: c
+
+    fd = seccomp(SECCOMP_SET_MODE_FILTER, SECCOMP_FILTER_FLAG_NEW_LISTENER, &prog);
+
+which (on success) will return a listener fd for the filter, which can then be
+passed around via ``SCM_RIGHTS`` or similar. Note that filter fds correspond to
+a particular filter, and not a particular task. So if this task then forks,
+notifications from both tasks will appear on the same filter fd. Reads and
+writes to/from a filter fd are also synchronized, so a filter fd can safely
+have many readers.
+
+The interface for a seccomp notification fd consists of two structures:
+
+.. code-block:: c
+
+    struct seccomp_notif_sizes {
+        __u16 seccomp_notif;
+        __u16 seccomp_notif_resp;
+        __u16 seccomp_data;
+    };
+
+    struct seccomp_notif {
+        __u64 id;
+        __u32 pid;
+        __u32 flags;
+        struct seccomp_data data;
+    };
+
+    struct seccomp_notif_resp {
+        __u64 id;
+        __s64 val;
+        __s32 error;
+        __u32 flags;
+    };
+
+The ``struct seccomp_notif_sizes`` structure can be used to determine the size
+of the various structures used in seccomp notifications. The size of ``struct
+seccomp_data`` may change in the future, so code should use:
+
+.. code-block:: c
+
+    struct seccomp_notif_sizes sizes;
+    seccomp(SECCOMP_GET_NOTIF_SIZES, 0, &sizes);
+
+to determine the size of the various structures to allocate. See
+samples/seccomp/user-trap.c for an example.
+
+Users can read via ``ioctl(SECCOMP_IOCTL_NOTIF_RECV)``  (or ``poll()``) on a
+seccomp notification fd to receive a ``struct seccomp_notif``, which contains
+five members: the input length of the structure, a unique-per-filter ``id``,
+the ``pid`` of the task which triggered this request (which may be 0 if the
+task is in a pid ns not visible from the listener's pid namespace), a ``flags``
+member which for now only has ``SECCOMP_NOTIF_FLAG_SIGNALED``, representing
+whether or not the notification is a result of a non-fatal signal, and the
+``data`` passed to seccomp. Userspace can then make a decision based on this
+information about what to do, and ``ioctl(SECCOMP_IOCTL_NOTIF_SEND)`` a
+response, indicating what should be returned to userspace. The ``id`` member of
+``struct seccomp_notif_resp`` should be the same ``id`` as in ``struct
+seccomp_notif``.
+
+It is worth noting that ``struct seccomp_data`` contains the values of register
+arguments to the syscall, but does not contain pointers to memory. The task's
+memory is accessible to suitably privileged traces via ``ptrace()`` or
+``/proc/pid/mem``. However, care should be taken to avoid the TOCTOU mentioned
+above in this document: all arguments being read from the tracee's memory
+should be read into the tracer's memory before any policy decisions are made.
+This allows for an atomic decision on syscall arguments.

Subject: selftests: forwarding: Add multicast routing test

Introduce basic testing for both IPv4 and IPv6 multicast. The test creates
an (S,G) type route, sends traffic and verifies traffic arrives when the
route is present and then verifies traffic does not arrive after deleting
the route.
This test requires smcroute - https://github.com/troglobit/smcroute which
is a tool that allows creation of static multicast routes.

Subject: selftests/bpf: use __bpf_constant_htons in test_prog.c

For some reason, my older GCC (< 4.8) isn't smart enough to optimize the
!__builtin_constant_p() branch in bpf_htons, I see:
  error: implicit declaration of function '__builtin_bswap16'

Let's use __bpf_constant_htons as suggested by Daniel Borkmann.

I tried to use simple htons, but it produces the following:
  test_progs.c:54:17: error: braced-group within expression allowed only
  inside a function
    .eth.h_proto = htons(ETH_P_IP),

kernel can provide the func_info and line_info even
it fails the btf_dump_raw_ok() test because they don't contain
kernel address.  This patch removes the corresponding '== 0'
test.

Subject: fix dma-buf/udmabuf selftest

This patch fixes the udmabuf selftest. Currently the selftest is broken.
I fixed the selftest by setting the F_SEAL_SHRINK seal on the memfd
file descriptor which is required by udmabuf and added the test to
the selftest Makefile.

Semantic of netns_id argument of bpf_sk_lookup_tcp and bpf_sk_lookup_udp
was changed (fixed) in f71c6143c203. Corresponding changes have to be
applied to all call sites in selftests. The patch fixes corresponding
call sites in test_sock_addr test: pass BPF_F_CURRENT_NETNS instead of 0
in netns_id argument.

Subject: selftests: Fix test errors related to lib.mk khdr target

Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added
khdr target to run headers_install target from the main Makefile. The
logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize
variables and include files to run headers_install from the top level
Makefile. There are a few problems with this logic.

1. Exposes top_srcdir to all tests
2. Common logic impacts all tests
3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests
   add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in
   some cases, and STATIC_LIBS in other cases. This makes this framework
   confusing to use.

The common logic that runs for all tests even when KSFT_KHDR_INSTALL
isn't defined by the test. top_srcdir is initialized to a default value
when test doesn't initialize it. It works for all tests without a sub-dir
structure and tests with sub-dir structure fail to build.

e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf

../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
make: *** No rule to make target '../../../../scripts/subarch.include'.  Stop.

There is no reason to require all tests to define top_srcdir and there is
no need to require tests to add khdr dependency using adhoc changes to
TEST_* and other variables.

Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests
that have the dependency on headers_install.

Change common logic to include khdr target define and "all" target with
dependency on khdr when KSFT_KHDR_INSTALL is defined.

Only tests that have dependency on headers_install have to define just
the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to
specify khdr dependency in the test Makefiles.

Subject: acpi/nfit, libnvdimm: Introduce nvdimm_security_ops

Some NVDIMMs, like the ones defined by the NVDIMM_FAMILY_INTEL command
set, expose a security capability to lock the DIMMs at poweroff and
require a passphrase to unlock them. The security model is derived from
ATA security. In anticipation of other DIMMs implementing a similar
scheme, and to abstract the core security implementation away from the
device-specific details, introduce nvdimm_security_ops.

Initially only a status retrieval operation, ->state(), is defined,
along with the base infrastructure and definitions for future
operations.

From 4c6926a23b76ea23403976290cd45a7a143f6500 Mon Sep 17 00:00:00 2001
From: Dave Jiang <dave.jiang@intel.com>
Date: Thu, 6 Dec 2018 12:40:01 -0800
Subject: acpi/nfit, libnvdimm: Add unlock of nvdimm support for Intel DIMMs

Add support to unlock the dimm via the kernel key management APIs. The
passphrase is expected to be pulled from userspace through keyutils.
The key management and sysfs attributes are libnvdimm generic.

Encrypted keys are used to protect the nvdimm passphrase at rest. The
master key can be a trusted-key sealed in a TPM, preferred, or an
encrypted-key, more flexible, but more exposure to a potential attacker.

must obey the same requirements as other RIFs. Test that attempts to
change the address incompatibly by attaching a device are vetoed with
extack.

Subject: kvm: introduce manual dirty log reprotect

There are two problems with KVM_GET_DIRTY_LOG.  First, and less important,
it can take kvm->mmu_lock for an extended period of time.  Second, its user
can actually see many false positives in some cases.  The latter is due
to a benign race like this:

  1. KVM_GET_DIRTY_LOG returns a set of dirty pages and write protects
     them.
  2. The guest modifies the pages, causing them to be marked ditry.
  3. Userspace actually copies the pages.
  4. KVM_GET_DIRTY_LOG returns those pages as dirty again, even though
     they were not written to since (3).

This is especially a problem for large guests, where the time between
(1) and (3) can be substantial.  This patch introduces a new
capability which, when enabled, makes KVM_GET_DIRTY_LOG not
write-protect the pages it returns.  Instead, userspace has to
explicitly clear the dirty log bits just before using the content
of the page.  The new KVM_CLEAR_DIRTY_LOG ioctl can also operate on a
64-page granularity rather than requiring to sync a full memslot;
this way, the mmu_lock is taken for small amounts of time, and
only a small amount of time will pass between write protection
of pages and the sending of their content.

+The ioctl clears the dirty status of pages in a memory slot, according to

+field.  Bit 0 of the bitmap corresponds to page "first_page" in the
+memory slot, and num_pages is the size in bits of the input bitmap.
+Both first_page and num_pages must be a multiple of 64.  For each bit
+that is set in the input bitmap, the corresponding page is marked "clean"

+
+With this capability enabled, KVM_GET_DIRTY_LOG will not automatically
+clear and write-protect all pages that are returned as dirty.
+Rather, userspace will have to do this operation separately using
+KVM_CLEAR_DIRTY_LOG.
+
+At the cost of a slightly more complicated operation, this provides better
+scalability and responsiveness for two reasons.  First,
+KVM_CLEAR_DIRTY_LOG ioctl can operate on a 64-page granularity rather
+than requiring to sync a full memslot; this ensures that KVM does not
+take spinlocks for an extended period of time.  Second, in some cases a
+large amount of time can pass between a call to KVM_GET_DIRTY_LOG and
+userspace actually using the data in the page.  Pages can be modified
+during this time, which is inefficint for both the guest and userspace:
+the guest will incur a higher penalty due to write protection faults,
+while userspace can see false reports of dirty pages.  Manual reprotection
+helps reducing this time, improving guest performance and reducing the
+number of dirty log false positives.

In case we want to test failing ioctls we need an option to not
fail. Following _vcpu_run() precedent implement _vcpu_ioctl().

Subject: selftests: net: test that listening sockets match on address properly

This patch adds a selftest that verifies that a socket listening
on a specific address is chosen in preference over sockets
that listen on any address. The test covers UDP/UDP6/TCP/TCP6.

It is based on, and similar to, reuseport_dualstack.c selftest.

Subject: bpf: improve stacksafe state comparison

"if (old->allocated_stack > cur->allocated_stack)" check is too conservative.
In some cases explored stack could have allocated more space,
but that stack space was not live.
The test case improves from 19 to 15 processed insns
and improvement on real programs is significant as well:

Subject: selftests: mlxsw: Add Bloom filter simple test

Add a test that exercises Bloom filter code.
Activate eRP table in the region by adding multiple rule patterns which
with very high probability use different entries in the Bloom filter.
Then send packets in order to check lookup hits on all relevant rules.

Add a test that exercises the possible combinations by creating
multiple chains using different key sizes and then pass a frame that

Subject: selftests: mlxsw: Add Bloom delta test

The eRP table is active when there is more than a single rule
pattern. It may be that the patterns are close enough and use delta
mechanism. Bloom filter index computation is based on the values of
{rule & mask, mask ID, region ID} where the rule delta bits must be
cleared.

Add a test that exercises Bloom filter with delta mechanism.
Configure rules within delta range and pass a packet which is
supposed to hit the correct rule.

Subject: selftests: Fix test errors related to lib.mk khdr target

Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added
khdr target to run headers_install target from the main Makefile. The
logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize
variables and include files to run headers_install from the top level
Makefile. There are a few problems with this logic.

1. Exposes top_srcdir to all tests
2. Common logic impacts all tests
3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests
   add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in
   some cases, and STATIC_LIBS in other cases. This makes this framework
   confusing to use.

The common logic that runs for all tests even when KSFT_KHDR_INSTALL
isn't defined by the test. top_srcdir is initialized to a default value
when test doesn't initialize it. It works for all tests without a sub-dir
structure and tests with sub-dir structure fail to build.

e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf

../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
make: *** No rule to make target '../../../../scripts/subarch.include'.  Stop.

There is no reason to require all tests to define top_srcdir and there is
no need to require tests to add khdr dependency using adhoc changes to
TEST_* and other variables.

Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests
that have the dependency on headers_install.

Change common logic to include khdr target define and "all" target with
dependency on khdr when KSFT_KHDR_INSTALL is defined.

Only tests that have dependency on headers_install have to define just
the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to
specify khdr dependency in the test Makefiles.

Subject: tools/bpf: add test_btf unit tests for kind_flag

This patch added unit tests for different types handling
type->info.kind_flag. The following new tests are added:
  $ test_btf
  ...
  BTF raw test[82] (invalid int kind_flag): OK
  BTF raw test[83] (invalid ptr kind_flag): OK
  BTF raw test[84] (invalid array kind_flag): OK
  BTF raw test[85] (invalid enum kind_flag): OK
  BTF raw test[86] (valid fwd kind_flag): OK
  BTF raw test[87] (invalid typedef kind_flag): OK
  BTF raw test[88] (invalid volatile kind_flag): OK
  BTF raw test[89] (invalid const kind_flag): OK
  BTF raw test[90] (invalid restrict kind_flag): OK
  BTF raw test[91] (invalid func kind_flag): OK
  BTF raw test[92] (invalid func_proto kind_flag): OK
  BTF raw test[93] (valid struct kind_flag, bitfield_size = 0): OK
  BTF raw test[94] (valid struct kind_flag, int member, bitfield_size != 0): OK
  BTF raw test[95] (valid union kind_flag, int member, bitfield_size != 0): OK
  BTF raw test[96] (valid struct kind_flag, enum member, bitfield_size != 0): OK
  BTF raw test[97] (valid union kind_flag, enum member, bitfield_size != 0): OK
  BTF raw test[98] (valid struct kind_flag, typedef member, bitfield_size != 0): OK
  BTF raw test[99] (valid union kind_flag, typedef member, bitfield_size != 0): OK
  BTF raw test[100] (invalid struct type, bitfield_size greater than struct size): OK
  BTF raw test[101] (invalid struct type, kind_flag bitfield base_type int not regular): OK
  BTF raw test[102] (invalid struct type, kind_flag base_type int not regular): OK
  BTF raw test[103] (invalid union type, bitfield_size greater than struct size): OK
  ...
  PASS:122 SKIP:0 FAIL:0

The second parameter name of macro
  BTF_INFO_ENC(kind, root, vlen)
in selftests test_btf.c is also renamed from "root" to "kind_flag".
Note that before this patch "root" is not used and always 0.

Subject: tools/bpf: check precise {func, line, jited_line}_info_rec_size in
 test_btf

Current btf func_info, line_info and jited_line are designed to be
extensible. The record sizes for {func,line}_info are passed to kernel,
and the record sizes for {func,line,jited_line}_info are returned to
userspace during bpf_prog_info query.

In bpf selftests test_btf.c, when testing whether kernel returns
a legitimate {func,line, jited_line)_info rec_size, the test only
compares to the minimum allowed size. If the returned rec_size is smaller
than the minimum allowed size, it is considered incorrect.
The minimum allowed size for these three info sizes are equal to
current value of sizeof(struct bpf_func_info), sizeof(struct bpf_line_info)
and sizeof(__u64).

The original thinking was that in the future when rec_size is increased
in kernel, the same test should run correctly. But this sacrificed
the precision of testing under the very kernel the test is shipped with,
and bpf selftest is typically run with the same repo kernel.

So this patch changed the testing of rec_size such that the
kernel returned value should be equal to the size defined by
tools uapi header bpf.h which syncs with kernel uapi header.

Martin discovered a bug in one of rec_size comparisons.
Instead of comparing to minimum func_info rec_size 8, it compares to 4.
This patch fixed that issue as well.

Fixes: 999d82cbc044 ("tools/bpf: enhance test_btf file testing to test func info")
Fixes: 05687352c600 ("bpf: Refactor and bug fix in test_func_type in test_btf.c")

Subject: bpf: correct slot_type marking logic to allow more stack slot sharing

Verifier is supposed to support sharing stack slot allocated to ptr with
SCALAR_VALUE for privileged program. However this doesn't happen for some
cases.

The reason is verifier is not clearing slot_type STACK_SPILL for all bytes,
it only clears part of them, while verifier is using:

  slot_type[0] == STACK_SPILL

as a convention to check one slot is ptr type.

So, the consequence of partial clearing slot_type is verifier could treat a
partially overridden ptr slot, which should now be a SCALAR_VALUE slot,
still as ptr slot, and rejects some valid programs.

Before this patch, test_xdp_noinline.o under bpf selftests, bpf_lxc.o and
bpf_netdev.o under Cilium bpf repo, when built with -mattr=+alu32 are
rejected due to this issue. After this patch, they all accepted.

There is no processed insn number change before and after this patch on
Cilium bpf programs.

Subject: bpf: Add BPF_LD_IMM64 to the line_info test

This patch adds a BPF_LD_IMM64 case to the line_info test
to ensure the kernel rejects linfo_info.insn_off pointing
to the 2nd 8 bytes of the BPF_LD_IMM64.

Subject: selftests: net: refactor reuseport_addr_any test

This patch refactors reuseport_add_any selftest a bit:
- makes it more modular (eliminates several copy/pasted blocks);
- skips DCCP tests if DCCP is not supported

V2: added "Signed-off-by" tag.

Subject: selftests: bpf: add trivial JSET tests

We seem to have no JSET instruction test, and LLVM does not
generate it at all, so let's add a simple hand-coded test
to make sure JIT implementations are correct.

v2:
 - extend test_verifier to handle multiple inputs and
   add the sample there (Daniel)
 - add a sign extension case

Subject: bpf: sk_msg, fix sk_msg_md access past end test

Currently, the test to ensure reads past the end of the sk_msg_md
data structure fail is incorrectly expecting success. Fix this
typo and use correct expected error.

Subject: selftests: mlxsw: Add a test case for L3 VNI

Previous patch added the ability to offload a VXLAN tunnel used for L3
VNI when it is present in the VLAN-aware bridge before the corresponding
VLAN interface is configured. This patch adds a test case to verify
that.

Subject: selftests: forwarding: Add router test with VID 1

Previous patches made it possible to setup VLAN devices with VID 1 over
mlxsw ports. Verify this functionality actually works by conducting a
simple router test over VID 1.

Adding this test as a generic test since it can be run using veth pairs
and it can also be useful for other physical devices where VID 1 was
considered reserved (knowingly or not).

Expand the transmit timestamp regression test with support for
missing protocols: ipv6 datagram and raw and pf_packet.

Also refine resolve_hostname to independently request AF_INET or
AF_INET6 addresses. Else, ipv4 addresses may be returned as AF_INET6.

From cda261f421ba2682e25f46beb229172706fc7fcd Mon Sep 17 00:00:00 2001
From: Willem de Bruijn <willemb@google.com>
Date: Thu, 20 Dec 2018 16:22:54 -0500
Subject: selftests: add txtimestamp kselftest

Run the transmit timestamp tests as part of kselftests.

Add a txtimestamp.sh test script that runs most variants:
ipv4/ipv6, tcp/udp/raw/raw_ipproto/pf_packet, data/nodata,
setsockopt/cmsg. The script runs tests with netem delays.

Refine txtimestamp.c to validate results. Take expected
netem delays as input and compare against real timestamps.

To run without dependencies, add a listener socket to be
able to connect in the case of TCP.

Add the timestamping directory to the kselftests Makefile.
Build all the binaries. Only run verified txtimestamp.sh.

Subject: selftests: net: reuseport_addr_any: silence clang warning

Clang does not recognize that calls to error() terminate execution
and complains about uninitialized variable use that happens after calls
to error(). This noop patchset fixes this.

Subject: selftests/powerpc: Add checks for transactional sigreturn

This is a new test case that creates a signal and starts a suspended
transaction inside the signal handler.

It returns from the signal handler with the CPU at suspended state, but
without setting user context MSR Transaction State (TS) field.

The kernel signal handler code should be able to handle this discrepancy
instead of crashing.

This code could be compiled and used to test 32 and 64-bits signal
handlers.

It isn't necessary and can even cause problems when testing high
guest physical addresses. This patch leaves the test memory id-
mapped by default, but when using '-t' the test memory virtual
addresses stay the same even though the physical addresses switch
to the topmost valid addresses.

There's no reason not to always test the topmost physical
addresses, and if the user wants to try lower addresses
then '-p' (used to be '-o before this patch) can be used.
Let's remove the '-t' option and just always do what it did.

Subject: kvm: selftests: ucall: fix exit mmio address guessing

Fix two more bugs in the exit_mmio address guessing.
The first bug was that the start and step calculations were
wrong since they were dividing the number of address bits instead
of the address space. The second other bug was that the guessing
algorithm wasn't considering the valid physical and virtual address
ranges correctly for an identity map.

Minor fallout from merge resolution, test_verifier was segfaulting
because the REJECT result was correct, but errstr was NULL. Properly
fix it as in 339bbff2d6e0.

Subject: tools/testing/nvdimm: Add test support for Intel nvdimm security DSMs

Add nfit_test support for DSM functions "Get Security State",
"Set Passphrase", "Disable Passphrase", "Unlock Unit", "Freeze Lock",
and "Secure Erase" for the fake DIMMs.

Also adding a sysfs knob in order to put the DIMMs in "locked" state. The
order of testing DIMM unlocking would be.
1a. Disable DIMM X.
1b. Set Passphrase to DIMM X.
2. Write to
/sys/devices/platform/nfit_test.0/nfit_test_dimm/test_dimmX/lock_dimm
3. Renable DIMM X
4. Check DIMM X state via sysfs "security" attribute for nmemX.

Subject: mm, devm_memremap_pages: mark devm_memremap_pages() EXPORT_SYMBOL_GPL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

devm_memremap_pages() is a facility that can create struct page entries
for any arbitrary range and give drivers the ability to subvert core
aspects of page management.

Specifically the facility is tightly integrated with the kernel's memory
hotplug functionality.  It injects an altmap argument deep into the
architecture specific vmemmap implementation to allow allocating from
specific reserved pages, and it has Linux specific assumptions about page
structure reference counting relative to get_user_pages() and
get_user_pages_fast().  It was an oversight and a mistake that this was
not marked EXPORT_SYMBOL_GPL from the outset.

Again, devm_memremap_pagex() exposes and relies upon core kernel internal
assumptions and will continue to evolve along with 'struct page', memory
hotplug, and support for new memory types / topologies.  Only an in-kernel
GPL-only driver is expected to keep up with this ongoing evolution.  This
interface, and functionality derived from this interface, is not suitable
for kernel-external drivers.

Subject: mm, devm_memremap_pages: fix shutdown handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The last step before devm_memremap_pages() returns success is to allocate
a release action, devm_memremap_pages_release(), to tear the entire setup
down.  However, the result from devm_add_action() is not checked.

Checking the error from devm_add_action() is not enough.  The api
currently relies on the fact that the percpu_ref it is using is killed by
the time the devm_memremap_pages_release() is run.  Rather than continue
this awkward situation, offload the responsibility of killing the
percpu_ref to devm_memremap_pages_release() directly.  This allows
devm_memremap_pages() to do the right thing relative to init failures and
shutdown.

Without this change we could fail to register the teardown of
devm_memremap_pages().  The likelihood of hitting this failure is tiny as
small memory allocations almost always succeed.  However, the impact of
the failure is large given any future reconfiguration, or disable/enable,
of an nvdimm namespace will fail forever as subsequent calls to
devm_memremap_pages() will fail to setup the pgmap_radix since there will
be stale entries for the physical address range.

An argument could be made to require that the ->kill() operation be set in
the @pgmap arg rather than passed in separately.  However, it helps code
readability, tracking the lifetime of a given instance, to be able to grep
the kill routine directly at the devm_memremap_pages() call site.

From: Daniel Borkmann <daniel@iogearbox.net>

Subject: bpf: add various test cases to selftests

Add various map value pointer related test cases to test_verifier
kselftest to reflect recent changes and improve test coverage. The
tests include basic masking functionality, unprivileged behavior
on pointer arithmetic which goes oob, mixed bounds tests, negative
unknown scalar but resulting positive offset for access and helper
range, handling of arithmetic from multiple maps, various masking
scenarios with subsequent map value access and others including two
test cases from Jann Horn for prior fixes.

Subject: selftests: net: fix/improve ip_defrag selftest

Commit ade446403bfb ("net: ipv4: do not handle duplicate fragments as
overlapping") changed IPv4 defragmentation so that duplicate fragments,
as well as _some_ fragments completely covered by previously delivered
fragments, do not lead to the whole frag queue being discarded. This
makes the existing ip_defrag selftest flaky.

This patch
* makes sure that negative IPv4 defrag tests generate truly overlapping
  fragments that trigger defrag queue drops;
* tests that duplicate IPv4 fragments do not trigger defrag queue drops;
* makes a couple of minor tweaks to the test aimed at increasing its code
  coverage and reduce flakiness.

Subject: selftests/bpf: Test [::] -> [::1] rewrite in sys_sendmsg in
 test_sock_addr

Test that sys_sendmsg BPF hook doesn't break sys_sendmsg behaviour to
rewrite destination IPv6 = [::] with [::1] (BSD'ism).

Two test cases are added:

1) User passes dst IPv6 = [::] and BPF_CGROUP_UDP6_SENDMSG program
   doesn't touch it.

2) User passes dst IPv6 != [::], but BPF_CGROUP_UDP6_SENDMSG program
   rewrites it with [::].

In both cases [::1] is used by sys_sendmsg code eventually and datagram
is sent successfully for unconnected UDP socket.

Example of relevant output:
  Test case: sendmsg6: set dst IP = [::] (BSD'ism) .. [PASS]
  Test case: sendmsg6: preserve dst IP = [::] (BSD'ism) .. [PASS]

Subject: bpf: add various test cases for alu op on mixed dst register types

Add couple of test_verifier tests to check sanitation of alu op insn
with pointer and scalar type coming from different paths. This also
includes BPF insns of the test reproducer provided by Jann Horn.

Subject: device-dax: Start defining a dax bus model

Towards eliminating the dax_class, move the dax-device-attribute
enabling to a new bus.c file in the core. The amount of code
thrash of sub-sequent patches is reduced as no logic changes are made,
just pure code movement.

A temporary export of unregister_dex_dax() and dax_attribute_groups is
needed to preserve compilation, but those symbols become static again in
a follow-on patch.

From 730926c3b0998943654019f00296cf8e3b02277e Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Sun, 16 Jul 2017 13:51:53 -0700
Subject: device-dax: Add /sys/class/dax backwards compatibility

On the expectation that some environments may not upgrade libdaxctl
(userspace component that depends on the /sys/class/dax hierarchy),
provide a default / legacy dax_pmem_compat driver. The dax_pmem_compat
driver implements the original /sys/class/dax sysfs layout rather than
/sys/bus/dax. When userspace is upgraded it can blacklist this module
and switch to the dax_pmem driver going forward.

CONFIG_DEV_DAX_PMEM_COMPAT and supporting code will be deleted according
to the dax_pmem entry in Documentation/ABI/obsolete/.

+What:           /sys/class/dax/
+Date:           May, 2016
+KernelVersion:  v4.7
+Contact:        linux-nvdimm@lists.01.org
+Description:	Device DAX is the device-centric analogue of Filesystem
+		DAX (CONFIG_FS_DAX).  It allows memory ranges to be
+		allocated and mapped without need of an intervening file
+		system.  Device DAX is strict, precise and predictable.
+		Specifically this interface:
+
+		1/ Guarantees fault granularity with respect to a given
+		page size (pte, pmd, or pud) set at configuration time.
+
+		2/ Enforces deterministic behavior by being strict about
+		what fault scenarios are supported.
+
+		The /sys/class/dax/ interface enumerates all the
+		device-dax instances in the system. The ABI is
+		deprecated and will be removed after 2020. It is

From a8911d6d5878587767a78c6bde371298ca2a3be3 Mon Sep 17 00:00:00 2001
From: Stanislav Fomichev <sdf@google.com>
Date: Mon, 7 Jan 2019 09:46:46 -0800
Subject: selftests/bpf: fix incorrect users of create_and_get_cgroup

We have some tests that assume create_and_get_cgroup returns -1 on error
which is incorrect (it returns 0 on error). Since fd might be zero in
general case, change create_and_get_cgroup to return -1 on error
and fix the users that assume 0 on error.

Fixes: f269099a7e7a ("tools/bpf: add a selftest for bpf_get_current_cgroup_id() helper")
Fixes: 7d2c6cfc5411 ("bpf: use --cgroup in test_suite if supplied")

v2:
- instead of fixing the uses that assume -1 on error, convert the users
  that assume 0 on error (fd might be zero in general case)

Subject: selftests: mlxsw: Add a test case for VLAN addition error flow

Add a test case for the issue fixed by previous commit. In case the
offloading of an unsupported VxLAN tunnel was triggered by adding the
mapped VLAN to a local port, then error should be returned to the user.

Subject: selftests: forwarding: Fix test for different devices

When running the test on the Spectrum ASIC the generated packets are
counted on the ingress filter and injected back to the pipeline because
of the 'pass' action. The router block then drops the packets due to
checksum error, as the test generates packets with zero checksum.

When running the test on an emulator that is not as strict about
checksum errors the test fails since packets are counted twice. Once by
the emulated ASIC on its ingress filter and again by the kernel as the
emulator does not perform checksum validation and allows the packets to
be trapped by a matching host route.

Fix this by changing the action to 'drop', which will prevent the packet
from continuing further in the pipeline to the router block.

For veth pairs this change is essentially a NOP given packets are only
processed once (by the kernel).

Subject: selftests: xfrm: add block rules with adjacent/overlapping subnets

The existing script lacks a policy pattern that triggers 'tree node
merges' in the kernel.

Consider adding policy affecting following subnet:
pol1: dst 10.0.0.0/22
pol2: dst 10.0.0.0/23 # adds to existing 10.0.0.0/22 node

-> no problems here.  But now, lets consider reverse order:
pol1: dst 10.0.0.0/24
pol2: dst 10.0.0.0/23 # CANNOT add to existing node

When second policy gets added, the kernel must check that the new node
("10.0.0.0/23") doesn't overlap with any existing subnet.

Example:
dst 10.0.0.0/24
dst 10.0.0.1/24
dst 10.0.0.0/23

When the third policy gets added, the kernel must replace the nodes for
the 10.0.0.0/24 and 10.0.0.1/24 policies with a single one and must merge
all the subtrees/lists stored in those nodes into the new node.

The existing test cases only have overlaps with a single node, so no
merging takes place (we can always remove the 'old' node and replace
it with the new subnet prefix).

Add a few 'block policies' in a pattern that triggers this, with a priority
that will make kernel prefer the 'esp' rules.

Make sure the 'tunnel ping' tests still pass after they have been added.

Subject: xfrm: policy: fix infinite loop when merging src-nodes

With very small change to test script we can trigger softlockup due to
bogus assignment of 'p' (policy to be examined) on restart.

Previously the two to-be-merged nodes had same address/prefixlength pair,
so no erase/reinsert was necessary, we only had to append the list from
node a to b.

If prefix lengths are different, the node has to be deleted and re-inserted
into the tree, with the updated prefix length.  This was broken; due to
bogus update to 'p' this loops forever.

Add a 'restart' label and use that instead.

While at it, don't perform the unneeded reinserts of the policies that
are already sorted into the 'new' node.

A previous patch in this series made xfrm_policy_inexact_list_reinsert()
use the relative position indicator to sort policies according to age in
case priorities are identical.

Subject: tools/bpf: test btf bitfield with >=256 struct member offset

This patch modified test_btf pretty print test to cover
the bitfield with struct member equal to or greater 256.

Without the previous kernel patch fix, the modified test will fail:

  $ test_btf -p
  ......
  BTF pretty print array(#1)......unexpected pprint output
  expected: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x1}
      read: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x0}

  BTF pretty print array(#2)......unexpected pprint output
  expected: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x1}

With the kernel fix, the modified test will succeed:
  $ test_btf -p

  BTF pretty print array(#2)......OK

Subject: selftests/livepatch: introduce tests

Add a few livepatch modules and simple target modules that the included
regression suite can run tests against:

  - basic livepatching (multiple patches, atomic replace)
  - pre/post (un)patch callbacks
  - shadow variable API

-Test cases
-==========
-
-What follows is not an exhaustive test suite of every possible livepatch
-pre/post-(un)patch combination, but a selection that demonstrates a few
-important concepts.  Each test case uses the kernel modules located in
-the samples/livepatch/ and assumes that no livepatches are loaded at the
-beginning of the test.
-
-
-Test 1
-------
-
-Test a combination of loading a kernel module and a livepatch that
-patches a function in the first module.  (Un)load the target module
-before the livepatch module:
-
-- load target module
-- load livepatch
-- disable livepatch
-- unload target module
-- unload livepatch
-
-First load a target module:
-
-  % insmod samples/livepatch/livepatch-callbacks-mod.ko
-  [   34.475708] livepatch_callbacks_mod: livepatch_callbacks_mod_init
-
-On livepatch enable, before the livepatch transition starts, pre-patch
-callbacks are executed for vmlinux and livepatch_callbacks_mod (those
-klp_objects currently loaded).  After klp_objects are patched according
-to the klp_patch, their post-patch callbacks run and the transition
-completes:
-
-  % insmod samples/livepatch/livepatch-callbacks-demo.ko
-  [   36.503719] livepatch: enabling patch 'livepatch_callbacks_demo'
-  [   36.504213] livepatch: 'livepatch_callbacks_demo': initializing patching transition
-  [   36.504238] livepatch_callbacks_demo: pre_patch_callback: vmlinux
-  [   36.504721] livepatch_callbacks_demo: pre_patch_callback: livepatch_callbacks_mod -> [MODULE_STATE_LIVE] Normal state
-  [   36.505849] livepatch: 'livepatch_callbacks_demo': starting patching transition
-  [   37.727133] livepatch: 'livepatch_callbacks_demo': completing patching transition
-  [   37.727232] livepatch_callbacks_demo: post_patch_callback: vmlinux

-  [   37.728792] livepatch: 'livepatch_callbacks_demo': patching complete
-
-Similarly, on livepatch disable, pre-patch callbacks run before the
-unpatching transition starts.  klp_objects are reverted, post-patch
-callbacks execute and the transition completes:
-
-  % echo 0 > /sys/kernel/livepatch/livepatch_callbacks_demo/enabled
-  [   38.510209] livepatch: 'livepatch_callbacks_demo': initializing unpatching transition
-  [   38.510234] livepatch_callbacks_demo: pre_unpatch_callback: vmlinux

-
-
-Test 2
-------
-
-This test is similar to the previous test, but (un)load the livepatch
-module before the target kernel module.  This tests the livepatch core's
-module_coming handler:
-
-- load livepatch
-- load target module
-- disable livepatch
-- unload livepatch
-- unload target module
-
-
-On livepatch enable, only pre/post-patch callbacks are executed for
-currently loaded klp_objects, in this case, vmlinux:
-
-  % insmod samples/livepatch/livepatch-callbacks-demo.ko
-  [   44.553328] livepatch: enabling patch 'livepatch_callbacks_demo'
-  [   44.553997] livepatch: 'livepatch_callbacks_demo': initializing patching transition

-
-When a targeted module is subsequently loaded, only its pre/post-patch
-callbacks are executed:

-
-On livepatch disable, all currently loaded klp_objects' (vmlinux and
-livepatch_callbacks_mod) pre/post-unpatch callbacks are executed:

-
-Test 3
-------
-
-Test loading the livepatch after a targeted kernel module, then unload
-the kernel module before disabling the livepatch.  This tests the
-livepatch core's module_going handler:
-
-- load target module
-- load livepatch
-- unload target module
-- disable livepatch
-- unload livepatch
-
-First load a target module, then the livepatch:
-
-  % insmod samples/livepatch/livepatch-callbacks-mod.ko

-  [   57.760307] livepatch: 'livepatch_callbacks_demo': patching complete
-
-When a target module is unloaded, the livepatch is only reverted from
-that klp_object (livepatch_callbacks_mod).  As such, only its pre and
-post-unpatch callbacks are executed when this occurs:
-
-  % rmmod samples/livepatch/livepatch-callbacks-mod.ko
-  [   58.623409] livepatch_callbacks_mod: livepatch_callbacks_mod_exit

-  [   58.625305] livepatch_callbacks_demo: post_unpatch_callback: livepatch_callbacks_mod -> [MODULE_STATE_GOING] Going away
-
-When the livepatch is disabled, pre and post-unpatch callbacks are run
-for the remaining klp_object, vmlinux:

-
-Test 4
-------
-
-This test is similar to the previous test, however the livepatch is
-loaded first.  This tests the livepatch core's module_coming and
-module_going handlers:
-
-- load livepatch
-- load target module
-- unload target module
-- disable livepatch

-
-First load the livepatch:

-Test 5
-------
-
-A simple test of loading a livepatch without one of its patch target
-klp_objects ever loaded (livepatch_callbacks_mod):
-
-- load livepatch
-- disable livepatch
-- unload livepatch
-
-Load the livepatch:
-
-  % insmod samples/livepatch/livepatch-callbacks-demo.ko
-  [   74.711081] livepatch: enabling patch 'livepatch_callbacks_demo'
-  [   74.711595] livepatch: 'livepatch_callbacks_demo': initializing patching transition

-  [   75.743867] livepatch: 'livepatch_callbacks_demo': patching complete
-
-As expected, only pre/post-(un)patch handlers are executed for vmlinux:
-
-  % echo 0 > /sys/kernel/livepatch/livepatch_callbacks_demo/enabled
-  [   76.716254] livepatch: 'livepatch_callbacks_demo': initializing unpatching transition

-
-Test 6
-------
-
-Test a scenario where a vmlinux pre-patch callback returns a non-zero
-status (ie, failure):
-
-- load target module
-- load livepatch -ENODEV
-- unload target module
-
-First load a target module:
-
-  % insmod samples/livepatch/livepatch-callbacks-mod.ko
-  [   80.740520] livepatch_callbacks_mod: livepatch_callbacks_mod_init
-
-Load the livepatch module, setting its 'pre_patch_ret' value to -19
-(-ENODEV).  When its vmlinux pre-patch callback executed, this status
-code will propagate back to the module-loading subsystem.  The result is
-that the insmod command refuses to load the livepatch module:
-
-  % insmod samples/livepatch/livepatch-callbacks-demo.ko pre_patch_ret=-19

-  [   84.774238] livepatch_callbacks_mod: livepatch_callbacks_mod_exit
-
-
-Test 7
-------
-
-Similar to the previous test, setup a livepatch such that its vmlinux
-pre-patch callback returns success.  However, when a targeted kernel
-module is later loaded, have the livepatch return a failing status code:
-
-- load livepatch
-- setup -ENODEV
-- load target module
-- disable livepatch

-The livepatch pre-patch callback for subsequently loaded target modules
-will return failure, so the module loader refuses to load the kernel
-module.  Notice that no post-patch or pre/post-unpatch callbacks are
-executed for this klp_object:

-Test 8
-------
-
-Test loading multiple targeted kernel modules.  This test-case is
-mainly for comparing with the next test-case.
-
-- load busy target module (0s sleep),
-- load livepatch
-- load target module
-- unload target module
-- disable livepatch
-- unload livepatch
-- unload busy target module
-
-
-Load a target "busy" kernel module which kicks off a worker function
-that immediately exits:
-
-  % insmod samples/livepatch/livepatch-callbacks-busymod.ko sleep_secs=0
-  [   96.910107] livepatch_callbacks_busymod: livepatch_callbacks_mod_init

-  [   96.913024] livepatch_callbacks_busymod: busymod_work_func exit
-
-Proceed with loading the livepatch and another ordinary target module,
-notice that the post-patch callbacks are executed and the transition
-completes quickly:

-Test 9
-------
-
-A similar test as the previous one, but force the "busy" kernel module
-to do longer work.
-
-The livepatching core will refuse to patch a task that is currently
-executing a to-be-patched function -- the consistency model stalls the
-current patch transition until this safety-check is met.  Test a
-scenario where one of a livepatch's target klp_objects sits on such a
-function for a long time.  Meanwhile, load and unload other target
-kernel modules while the livepatch transition is in progress.
-
-- load busy target module (30s sleep)
-- load livepatch
-- load target module
-- unload target module
-- disable livepatch
-- unload livepatch
-- unload busy target module
-
-
-Load the "busy" kernel module, this time make it do 30 seconds worth of
-work:
-
-  % insmod samples/livepatch/livepatch-callbacks-busymod.ko sleep_secs=30
-  [  110.993362] livepatch_callbacks_busymod: livepatch_callbacks_mod_init
-  [  110.994059] livepatch_callbacks_busymod: busymod_work_func, sleeping 30 seconds ...
-
-Meanwhile, the livepatch is loaded.  Notice that the patch transition
-does not complete as the targeted "busy" module is sitting on a
-to-be-patched function:
-
-  % insmod samples/livepatch/livepatch-callbacks-demo.ko
-  [  113.000309] livepatch: enabling patch 'livepatch_callbacks_demo'
-  [  113.000764] livepatch: 'livepatch_callbacks_demo': initializing patching transition
-  [  113.000791] livepatch_callbacks_demo: pre_patch_callback: vmlinux
-  [  113.001289] livepatch_callbacks_demo: pre_patch_callback: livepatch_callbacks_busymod -> [MODULE_STATE_LIVE] Normal state
-  [  113.005208] livepatch: 'livepatch_callbacks_demo': starting patching transition
-
-Load a second target module (this one is an ordinary idle kernel
-module).  Note that *no* post-patch callbacks will be executed while the
-livepatch is still in transition:
-
-  % insmod samples/livepatch/livepatch-callbacks-mod.ko
-  [  115.012740] livepatch: applying patch 'livepatch_callbacks_demo' to loading module 'livepatch_callbacks_mod'
-  [  115.013406] livepatch_callbacks_demo: pre_patch_callback: livepatch_callbacks_mod -> [MODULE_STATE_COMING] Full formed, running module_init
-  [  115.015315] livepatch_callbacks_mod: livepatch_callbacks_mod_init
-
-Request an unload of the simple kernel module.  The patch is still
-transitioning, so its pre-unpatch callbacks are skipped:
-
-  % rmmod samples/livepatch/livepatch-callbacks-mod.ko
-  [  117.022626] livepatch_callbacks_mod: livepatch_callbacks_mod_exit
-  [  117.023376] livepatch: reverting patch 'livepatch_callbacks_demo' on unloading module 'livepatch_callbacks_mod'
-  [  117.024533] livepatch_callbacks_demo: post_unpatch_callback: livepatch_callbacks_mod -> [MODULE_STATE_GOING] Going away
-
-Finally the livepatch is disabled.  Since none of the patch's
-klp_object's post-patch callbacks executed, the remaining klp_object's
-pre-unpatch callbacks are skipped:
-
-  % echo 0 > /sys/kernel/livepatch/livepatch_callbacks_demo/enabled
-  [  119.035408] livepatch: 'livepatch_callbacks_demo': reversing transition from patching to unpatching
-  [  119.035485] livepatch: 'livepatch_callbacks_demo': starting unpatching transition

-  [  119.714653] livepatch_callbacks_demo: post_unpatch_callback: livepatch_callbacks_busymod -> [MODULE_STATE_LIVE] Normal state
-  [  119.715437] livepatch: 'livepatch_callbacks_demo': unpatching complete
-
-  % rmmod samples/livepatch/livepatch-callbacks-demo.ko
-  % rmmod samples/livepatch/livepatch-callbacks-busymod.ko
-  [  141.279111] livepatch_callbacks_busymod: busymod_work_func exit
-  [  141.279760] livepatch_callbacks_busymod: livepatch_callbacks_mod_exit

+====================
+Livepatch Self Tests
+====================
+
+This is a small set of sanity tests for the kernel livepatching.
+
+The test suite loads and unloads several test kernel modules to verify
+livepatch behavior.  Debug information is logged to the kernel's message
+buffer and parsed for expected messages.  (Note: the tests will clear
+the message buffer between individual tests.)
+
+
+Config
+------
+
+Set these config options and their prerequisites:
+
+CONFIG_LIVEPATCH=y
+CONFIG_TEST_LIVEPATCH=m
+
+
+Running the tests
+-----------------
+
+Test kernel modules are built as part of lib/ (make modules) and need to
+be installed (make modules_install) as the test scripts will modprobe
+them.
+
+To run the livepatch selftests, from the top of the kernel source tree:
+
+  % make -C tools/testing/selftests TARGETS=livepatch run_tests
+
+
+Adding tests
+------------
+
+See the common functions.sh file for the existing collection of utility
+functions, most importantly set_dynamic_debug() and check_result().  The
+latter function greps the kernel's ring buffer for "livepatch:" and
+"test_klp" strings, so tests be sure to include one of those strings for
+result comparison.  Other utility functions include general module
+loading and livepatch loading helpers (waiting for patch transitions,
+sysfs entries, etc.)

+# patches a function in the first module.  Load the target module
+# before the livepatch module.  Unload them in the same order.
+#
+# - On livepatch enable, before the livepatch transition starts,
+#   pre-patch callbacks are executed for vmlinux and $MOD_TARGET (those
+#   klp_objects currently loaded).  After klp_objects are patched
+#   according to the klp_patch, their post-patch callbacks run and the
+#   transition completes.
+#
+# - Similarly, on livepatch disable, pre-patch callbacks run before the
+#   unpatching transition starts.  klp_objects are reverted, post-patch
+#   callbacks execute and the transition completes.

From a65329aa7d613288626275546074f1aae5a04965 Mon Sep 17 00:00:00 2001
From: Breno Leitao <leitao@debian.org>
Date: Tue, 8 Jan 2019 09:31:21 -0200
Subject: selftests/powerpc: New TM signal self test

A new self test that forces MSR[TS] to be set without calling any TM
instruction. This test also tries to cause a page fault at a signal
handler, exactly between MSR[TS] set and tm_recheckpoint(), forcing
thread->texasr to be rewritten with TEXASR[FS] = 0, which will cause a BUG
when tm_recheckpoint() is called.

This test is not deterministic, since it is hard to guarantee that the page
access will cause a page fault. In order to force more page faults at
signal context, the signal handler and the ucontext are being mapped into a
MADV_DONTNEED memory chunks.

Tests have shown that the bug could be exposed with few interactions in a
buggy kernel. This test is configured to loop 5000x, having a good chance
to hit the kernel issue in just one run.  This self test takes less than
two seconds to run.

This test uses set/getcontext because the kernel will recheckpoint
zeroed structures, causing the test to segfault, which is undesired because
the test needs to rerun, so, there is a signal handler for SIGSEGV which
will restart the test.

v2: Uses the MADV_DONTNEED memory advice
v3: Fix memcpy and 32-bits compilation
v4: Does not define unused macros

Subject: x86/selftests/pkeys: Fork() to check for state being preserved

There was a bug where the per-mm pkey state was not being preserved across
fork() in the child.  fork() is performed in the pkey selftests, but all of
the pkey activity is performed in the parent.  The child does not perform
any actions sensitive to pkey state.

To make the test more sensitive to these kinds of bugs, add a fork() where
the parent exits, and execution continues in the child.

To achieve this let the key exhaustion test not terminate at the first
allocation failure and fork after 2*NR_PKEYS loops and continue in the
child.

 unspecified

After commit 1c25324caf82 ("net/sched: act_tunnel_key: Don't dump dst port
if it wasn't set"), act_tunnel_key doesn't dump anymore the destination
port, unless it was explicitly configured. This caused systematic failures
in the following TDC test case:

 7a88 - Add tunnel_key action with cookie parameter

Avoid matching zero values of TCA_TUNNEL_KEY_ENC_DST_PORT to let the test
pass again.

It's GNU Make and linker specific.

The default Makefile rule looks like:

$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)

When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.

More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.

LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.

https://lkml.org/lkml/2010/2/10/362

tools/perf: libraries must come after objects

Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libpthread.

Subject: tools/bpf: add int128 raw test in test_btf

Several int128 raw type tests are added to test_btf.
Currently these tests are enabled only for x64 and arm64
for which kernel has CONFIG_ARCH_SUPPORTS_INT128 set.

  $ test_btf

Subject: tools/bpf: refactor test_btf pretty printing for multiple map value
 formats

The test_btf pretty print is refactored in order to easily
support multiple map value formats. The next patch will
add __int128 type tests which needs macro guard __SIZEOF_INT128__.
There is no functionality change with this patch.

Subject: selftests: tc-testing: fix parsing of ife type

In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format
specifier for the ife type changed from 0x%X to %#llX, causing systematic
failures in the following TDC test cases:

 7682 - Create valid ife encode action with mark and pass control
 ef47 - Create valid ife encode action with mark and pipe control
 df43 - Create valid ife encode action with mark and continue control
 e4cf - Create valid ife encode action with mark and drop control
 ccba - Create valid ife encode action with mark and reclassify control
 a1cf - Create valid ife encode action with mark and jump control
 cb3d - Create valid ife encode action with mark value at 32-bit maximum
 95ed - Create valid ife encode action with prio and pass control
 aa17 - Create valid ife encode action with prio and pipe control
 74c7 - Create valid ife encode action with prio and continue control
 7a97 - Create valid ife encode action with prio and drop control
 f66b - Create valid ife encode action with prio and reclassify control
 3056 - Create valid ife encode action with prio and jump control
 7dd3 - Create valid ife encode action with prio value at 32-bit maximum
 05bb - Create valid ife encode action with tcindex and pass control
 ce65 - Create valid ife encode action with tcindex and pipe control
 09cd - Create valid ife encode action with tcindex and continue control
 8eb5 - Create valid ife encode action with tcindex and continue control
 451a - Create valid ife encode action with tcindex and drop control
 d76c - Create valid ife encode action with tcindex and reclassify control
 e731 - Create valid ife encode action with tcindex and jump control
 b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum
 2a9c - Create valid ife encode action with mac src parameter
 cf5c - Create valid ife encode action with mac dst parameter
 2353 - Create valid ife encode action with mac src and mac dst parameters
 552c - Create valid ife encode action with mark and type parameters
 0421 - Create valid ife encode action with prio and type parameters
 4017 - Create valid ife encode action with tcindex and type parameters
 fac3 - Create valid ife encode action with index at 32-bit maximnum
 7c25 - Create valid ife decode action with pass control
 dccb - Create valid ife decode action with pipe control
 7bb9 - Create valid ife decode action with continue control
 d9ad - Create valid ife decode action with drop control
 219f - Create valid ife decode action with reclassify control
 8f44 - Create valid ife decode action with jump control
 b330 - Create ife encode action with cookie

Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal
to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass
both with old and new tc binaries.
While at it, fix a small typo in test case fac3 ('maximnum'->'maximum').

Subject: selftests/bpf: retry tests that expect build-id

While running test_progs in a loop I found out that I'm sometimes hitting
"Didn't find expected build ID from the map" error.

Looking at stack_map_get_build_id_offset() it seems that it is racy (by
design) and can sometimes return BPF_STACK_BUILD_ID_IP (i.e. can't trylock
current->mm->mmap_sem).

Let's retry this test a single time.

Fixes: 13790d1cc72c ("bpf: add selftest for stackmap with build_id in NMI context")

Subject: selftests/seccomp: Abort without user notification support

In the face of missing user notification support, the self test needs
to stop executing a test (ASSERT_*) instead of just reporting and
continuing (EXPECT_*). This adjusts the user notification tests to do
that where needed.

Subject: selftests/tls: Fix recv partial/large_buff test cases

TLS test cases recv_partial & recv_peek_large_buf_mult_recs expect to
receive a certain amount of data and then compare it against known
strings using memcmp. To prevent recvmsg() from returning lesser than
expected number of bytes (compared in memcmp), MSG_WAITALL needs to be
passed in recvmsg().

mlxsw doesn't implement offloading of all types of FDB entries that the
VXLAN driver supports. Test that such FDB entries are rejected. That
makes sure that the decision made by the existing validation code in
mlxsw propagates up the stack. It also exercises rollback functionality
in VXLAN, and tests that extack is returned.

Subject: selftests: forwarding: Add IP tunneling lib

Add a library with helper functions, to be used in testing IP-in-IP and GRE
tunnels, both in flat and in hierarchical topologies.
The topologies used in this library cover the three scenarios of tunnels -
a tunel with no bound device, a tunnel with bound device in the same VRF
and a tunnel with a bound device in a different VRF.

Subject: selftests: forwarding: Add a test for VXLAN asymmetric routing

In asymmetric routing the ingress VTEP routes the packet into the
correct VXLAN tunnel, whereas the egress VTEP only bridges the packet to
the correct host. Therefore, packets in different directions use
different VNIs - the target VNI.

The test uses a simple topology with two VTEPs and two VNIs and verifies
that ping passes between hosts (local / remote) in the same VLAN (VNI)
and in different VLANs belonging to the same tenant (VRF).

While the test does not check VM mobility, it does configure an anycast
gateway using a macvlan device on both VTEPs.

Subject: selftests: forwarding: Add a test case for ARP decapsulation

Verify that ARP packets are correctly decapsulated by the ingress VTEP
by removing the neighbours configured on both VLAN interfaces and
running a ping test.

Subject: selftests: forwarding: Add a test for VXLAN symmetric routing

In a similar fashion to the asymmetric test, add a test for symmetric
routing. In symmetric routing both the ingress and egress VTEPs perform
routing in the overlay network into / from the VXLAN tunnel. Packets in
different directions use the same VNI - the L3 VNI. Different tenants
(VRFs) use different L3 VNIs.

Subject: selftests: forwarding: Add a test case for ARP suppression

ARP suppression allows the Linux bridge to answer ARP requests on behalf
of remote hosts. It reduces the amount of packets a VTEP needs to flood.

This test verifies that ARP suppression on / off works when a neighbour
exists and when it does not exist. It does so by sending an ARP request
from a host connected to one VTEP and checking whether it was received
by a second VTEP.

Subject: libbpf: Show supported ELF section names when failing to guess
 prog/attach type

We need to let users check their wrong ELF section name with proper
ELF section names when they fail to get a prog/attach type from it.
Because users can't realize libbpf guess prog/attach types from given
ELF section names. For example, when a 'cgroup' section name of a
BPF program is used, show available ELF section names(types).

Before:

    $ bpftool prog load bpf-prog.o /sys/fs/bpf/prog1
    Error: failed to guess program type based on ELF section name cgroup

After:

    libbpf: failed to guess program type based on ELF section name 'cgroup'
    libbpf: supported section(type) names are: socket kprobe/ kretprobe/ classifier action tracepoint/ raw_tracepoint/ xdp perf_event lwt_in lwt_out lwt_xmit lwt_seg6local cgroup_skb/ingress cgroup_skb/egress cgroup/skb cgroup/sock cgroup/post_bind4 cgroup/post_bind6 cgroup/dev sockops sk_skb/stream_parser sk_skb/stream_verdict sk_skb sk_msg lirc_mode2 flow_dissector cgroup/bind4 cgroup/bind6 cgroup/connect4 cgroup/connect6 cgroup/sendmsg4 cgroup/sendmsg6

Subject: selftests/bpf: don't hardcode iptables/nc path in test_tcpnotify_user

system() is calling shell which should find the appropriate full path
via $PATH. On some systems, full path to iptables and/or nc might be
different that we one we have hardcoded.

Subject: selftests: bpf: add tests for dead code removal

Add tests for newly added dead code elimination.  Both verifier
and BTF tests are added.  BTF test infrastructure has to be
extended to be able to account for line info which is eliminated
during dead code removal.

Date: Wed, 23 Jan 2019 09:22:27 -0800
Subject: bpf: allow BPF programs access skb_shared_info->gso_segs field

This adds the ability to read gso_segs from a BPF program.

v3: Use BPF_REG_AX instead of BPF_REG_TMP for the temporary register,
    as suggested by Martin.

v2: refined Eddie Hao patch to address Alexei feedback.

After:
$ make -s -C tools/testing/selftests/bpf

v2:
* use llvm-readelf instead of redirecting binutils' readelf stderr to

Subject: kvm: selftests: Fix region overlap check in kvm_util

Fix a call to userspace_mem_region_find to conform to its spec of
taking an inclusive, inclusive range. It was previously being called
with an inclusive, exclusive range. Also remove a redundant region bounds
check in vm_userspace_mem_region_add. Region overlap checking is already
performed by the call to userspace_mem_region_find.

Tested: Compiled tools/testing/selftests/kvm with -static
	Ran all resulting test binaries on an Intel Haswell test machine
	All tests passed

Subject: selftests: cpu-hotplug: fix case where CPUs offline > CPUs present

The cpu-hotplug test assumes that we can offline the maximum CPU as
described by /sys/devices/system/cpu/offline.  However, in the case
where the number of CPUs exceeds like kernel configuration then
the offline count can be greater than the present count and we end
up trying to test the offlining of a CPU that is not available to
offline.  Fix this by testing the maximum present CPU instead.

Also, the test currently offlines the CPU and does not online it,
so fix this by onlining the CPU after the test.

Subject: selftests/seccomp: Enhance per-arch ptrace syscall skip tests

Passing EPERM during syscall skipping was confusing since the test wasn't
actually exercising the errno evaluation -- it was just passing a literal
"1" (EPERM). Instead, expand the tests to check both direct value returns
(positive, 45000 in this case), and errno values (negative, -ESRCH in this
case) to check both fake success and fake failure during syscall skipping.

Subject: torture: Explain and simplify odd "for" loop in mkinitrd.sh

Why a Bourne-shell "for" loop?  And why 192 instances of "a"?  This commit
adds a shell comment to present the answer to these mysteries.  It also
uses a series of factor-of-four Bourne-shell assignments to make it
easy to see how many instances there are, replacing the earlier wall of
'a' characters.

Subject: rcutorture/nolibc: Fix some poor indentation and alignment

A few macros had their rightmost backslash misaligned, and the pollfd
struct definition resisted the previous code reindent. Nothing else
changed.

Subject: rcutorture/nolibc: Add a bit of documentation to explain how to use
 nolibc

Ingo rightfully asked for a bit more documentation in the nolibc header,
so this patch adds some explanation about its purpose, how it's made, and
how to use it.

+ * This file is designed to be used as a libc alternative for minimal programs

+ * type definitions, and the minimal startup code needed to call main().
+ * All syscalls are declared as static functions so that they can be optimized
+ * away by the compiler when not used.
+ *
+ * Syscalls are split into 3 levels:
+ *   - The lower level is the arch-specific syscall() definition, consisting in
+ *     assembly code in compound expressions. These are called my_syscall0() to
+ *     my_syscall6() depending on the number of arguments. The MIPS
+ *     implementation is limited to 5 arguments. All input arguments are cast
+ *     to a long stored in a register. These expressions always return the
+ *     syscall's return value as a signed long value which is often either a
+ *     pointer or the negated errno value.
+ *
+ *   - The second level is mostly architecture-independent. It is made of
+ *     static functions called sys_<name>() which rely on my_syscallN()
+ *     depending on the syscall definition. These functions are responsible
+ *     for exposing the appropriate types for the syscall arguments (int,
+ *     pointers, etc) and for setting the appropriate return type (often int).
+ *     A few of them are architecture-specific because the syscalls are not all
+ *     mapped exactly the same among architectures. For example, some archs do
+ *     not implement select() and need pselect6() instead, so the sys_select()
+ *     function will have to abstract this.
+ *
+ *   - The third level is the libc call definition. It exposes the lower raw
+ *     sys_<name>() calls in a way that looks like what a libc usually does,
+ *     takes care of specific input values, and of setting errno upon error.
+ *     There can be minor variations compared to standard libc calls. For
+ *     example the open() call always takes 3 args here.
+ *
+ * The errno variable is declared static and unused. This way it can be
+ * optimized away if not used. However this means that a program made of
+ * multiple C files may observe different errno values (one per C file). For
+ * the type of programs this project targets it usually is not a problem. The
+ * resulting program may even be reduced by defining the NOLIBC_IGNORE_ERRNO
+ * macro, in which case the errno value will never be assigned.
+ *
+ * Some stdint-like integer types are defined. These are valid on all currently
+ * supported architectures, because signs are enforced, ints are assumed to be
+ * 32 bits, longs the size of a pointer and long long 64 bits. If more
+ * architectures have to be supported, this may need to be adapted.
+ *
+ * Some macro definitions like the O_* values passed to open(), and some
+ * structures like the sys_stat struct depend on the architecture.
+ *
+ * The definitions start with the architecture-specific parts, which are picked
+ * based on what the compiler knows about the target architecture, and are
+ * completed with the generic code. Since it is the compiler which sets the
+ * target architecture, cross-compiling normally works out of the box without
+ * having to specify anything.
+ *
+ * Finally some very common libc-level functions are provided. It is the case
+ * for a few functions usually found in string.h, ctype.h, or stdlib.h. Nothing
+ * is currently provided regarding stdio emulation.
+ *
+ * The macro NOLIBC is always defined, so that it is possible for a program to
+ * check this macro to know if it is being built against and decide to disable
+ * some features or simply not to include some standard libc files.
+ *
+ * Ideally this file should be split in multiple files for easier long term
+ * maintenance, but provided as a single file as it is now, it's quite
+ * convenient to use. Maybe some variations involving a set of includes at the

Subject: tools headers: Move the nolibc header from rcutorture to
 tools/include/nolibc/

As suggested by Ingo, this header file might benefit other tools than
just rcutorture. For now it's quite limited, but is easy to extend, so
exposing it into tools/include/nolibc/ will make it much easier to
adopt by other tools.

The mkinitrd.sh script in rcutorture was updated to use this new location.

+ *     scall32-o32.S in the kernel sources.
+ *   - the system call is performed by calling "syscall"
+ *   - syscall return comes in v0, and register a3 needs to be checked to know
+ *     if an error occured, in which case errno is in v0.
+ *   - the arguments are cast to long and assigned into the target registers

- * This file is designed to be used as a libc alternative for minimal programs
- * with very limited requirements. It consists of a small number of syscall and
- * type definitions, and the minimal startup code needed to call main().
- * All syscalls are declared as static functions so that they can be optimized
- * away by the compiler when not used.
- *
- * Syscalls are split into 3 levels:
- *   - The lower level is the arch-specific syscall() definition, consisting in
- *     assembly code in compound expressions. These are called my_syscall0() to
- *     my_syscall6() depending on the number of arguments. The MIPS
- *     implementation is limited to 5 arguments. All input arguments are cast
- *     to a long stored in a register. These expressions always return the
- *     syscall's return value as a signed long value which is often either a
- *     pointer or the negated errno value.
- *
- *   - The second level is mostly architecture-independent. It is made of
- *     static functions called sys_<name>() which rely on my_syscallN()
- *     depending on the syscall definition. These functions are responsible
- *     for exposing the appropriate types for the syscall arguments (int,
- *     pointers, etc) and for setting the appropriate return type (often int).
- *     A few of them are architecture-specific because the syscalls are not all
- *     mapped exactly the same among architectures. For example, some archs do
- *     not implement select() and need pselect6() instead, so the sys_select()
- *     function will have to abstract this.
- *
- *   - The third level is the libc call definition. It exposes the lower raw
- *     sys_<name>() calls in a way that looks like what a libc usually does,
- *     takes care of specific input values, and of setting errno upon error.
- *     There can be minor variations compared to standard libc calls. For
- *     example the open() call always takes 3 args here.
- *
- * The errno variable is declared static and unused. This way it can be
- * optimized away if not used. However this means that a program made of
- * multiple C files may observe different errno values (one per C file). For
- * the type of programs this project targets it usually is not a problem. The
- * resulting program may even be reduced by defining the NOLIBC_IGNORE_ERRNO
- * macro, in which case the errno value will never be assigned.
- *
- * Some stdint-like integer types are defined. These are valid on all currently
- * supported architectures, because signs are enforced, ints are assumed to be
- * 32 bits, longs the size of a pointer and long long 64 bits. If more
- * architectures have to be supported, this may need to be adapted.
- *
- * Some macro definitions like the O_* values passed to open(), and some
- * structures like the sys_stat struct depend on the architecture.
- *
- * The definitions start with the architecture-specific parts, which are picked
- * based on what the compiler knows about the target architecture, and are
- * completed with the generic code. Since it is the compiler which sets the
- * target architecture, cross-compiling normally works out of the box without
- * having to specify anything.
- *
- * Finally some very common libc-level functions are provided. It is the case
- * for a few functions usually found in string.h, ctype.h, or stdlib.h. Nothing
- * is currently provided regarding stdio emulation.
- *
- * The macro NOLIBC is always defined, so that it is possible for a program to
- * check this macro to know if it is being built against and decide to disable
- * some features or simply not to include some standard libc files.
- *
- * Ideally this file should be split in multiple files for easier long term
- * maintenance, but provided as a single file as it is now, it's quite
- * convenient to use. Maybe some variations involving a set of includes at the
- * top could work.
- *
- * A simple static executable may be built this way :
- *      $ gcc -fno-asynchronous-unwind-tables -fno-ident -s -Os -nostdlib \
- *            -static -include nolibc.h -lgcc -o hello hello.c
- *
- * A very useful calling convention table may be found here :
- *      http://man7.org/linux/man-pages/man2/syscall.2.html
- *
- * This doc is quite convenient though not necessarily up to date :
- *      https://w3challs.com/syscalls/
- *
- */
-
-/* Some archs (at least aarch64) don't expose the regular syscalls anymore by
- * default, either because they have an "_at" replacement, or because there are
- * more modern alternatives. For now we'd rather still use them.

- *   - stack is 8-byte aligned
- *   - syscall number is passed in v0 (starts at 0xfa0).
- *   - arguments are in a0, a1, a2, a3, then the stack. The caller needs to

- *   - Many registers are clobbered, in fact only a0..a2 and s0..s8 are
- *     preserved. See: https://www.linux-mips.org/wiki/Syscall as well as
- *     scall32-o32.S in the kernel sources.
- *   - the system call is performed by calling "syscall"
- *   - syscall return comes in v0, and register a3 needs to be checked to know
- *     if an error occured, in which case errno is in v0.
- *   - the arguments are cast to long and assigned into the target registers

Subject: selftests: net: ip_defrag: cover new IPv6 defrag behavior

This patch adds several changes to the ip_defrag selftest, to cover
new IPv6 defrag behavior:

- min IPv6 frag size is now 8 instead of 1280

- new test cases to cover IPv6 defragmentation in nf_conntrack_reasm.c

- new "permissive" mode in negative (overlap) tests: netfilter
sometimes drops invalid packets without passing them to IPv6
underneath, and thus defragmentation sometimes succeeds when
it is expected to fail; so the permissive mode does not fail the
test if the correct reassembled datagram is received instead of a
timeout.

From 6ea848b5ced53cbfd5677ff176c2aca10fd61bf4 Mon Sep 17 00:00:00 2001
From: Jiong Wang <jiong.wang@netronome.com>

Subject: selftests: bpf: functional and min/max reasoning unit tests for JMP32

This patch adds unit tests for new JMP32 instructions.

This patch also added the new BPF_JMP32_REG and BPF_JMP32_IMM macros to
samples/bpf/bpf_insn.h so that JMP32 insn builders are available to tests
under 'samples' directory.

Subject: selftests: bpf: makefile support sub-register code-gen test mode

This patch enables testing some eBPF programs under sub-register
compilation mode.

Only enable this when there is BPF_JMP32 support on both LLVM and kernel.
This is because only after BPF_JMP32 added, code-gen for complex program
under sub-register mode will be clean enough to pass verification.

This patch splits TEST_GEN_FILES into BPF_OBJ_FILES and
BPF_OBJ_FILES_DUAL_COMPILE. The latter are those objects we would like to
compile for both default and sub-register mode. They are also objects used
by "test_progs".

Subject: selftests: bpf: prepare for break up of verifier tests

test_verifier.c has grown to be very long (almost 16 kLoC),
and it is very conflict prone since we always add tests at
the end.

Try to break it apart a little bit.  Allow test snippets
to be defined in separate files and include them automatically
into the huge test array.

Subject: selftests: bpf: break up test_verifier

Break up the first 10 kLoC of test verifier test cases
out into smaller files.  Looks like git line counting
gets a little flismy above 16 bit integers, so we need
two commits to break up test_verifier.

 undefined reference to `numa_max_node'

It's GNU Make and linker specific.

The default Makefile rule looks like:

$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)

When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.

More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.

LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.

https://lkml.org/lkml/2010/2/10/362

tools/perf: libraries must come after objects

Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libnuma.

Use existing pkt_v4 and pkt_v6 to make sure flow_keys are what we want.

Also, add new bpf_flow_load routine (and flow_dissector_load.h header)
that loads bpf_flow.o program and does all required setup.

Subject: selftests: add binderfs selftests

This adds the promised selftest for binderfs. It will verify the following
things:
- binderfs mounting works
- binder device allocation works
- performing a binder ioctl() request through a binderfs device works
- binder device removal works
- binder-control removal fails
- binderfs unmounting works

The tests are performed both privileged and unprivileged. The latter
verifies that binderfs behaves correctly in user namespaces.

Subject: selftests: spectrum-2: Fix multiple_masks_test

With recent fix in C-TCAM spillage for delta masks, the test stops to be
falsely positive. So fix it not to use delta by adding src_ip bits to the
masks. Alongside with that, use C-TCAM spill trace to see when the
spillage actually happens.

Use recently introduced bpf_probe_map_type() to skip tests in the
test_verifier if map creation (create_map) fails. It's handled
explicitly for each fixup, i.e. if bpf_create_map returns negative fd,
we probe the kernel for the appropriate map support and skip the
test is map type is not supported.

Subject: selftests/bpf: mark verifier test that uses bpf_trace_printk as
 BPF_PROG_TYPE_TRACEPOINT

We don't have this helper if the kernel was compiled without
CONFIG_BPF_EVENTS. Setting prog_type to BPF_PROG_TYPE_TRACEPOINT
let's verifier correctly skip this test based on the missing
prog_type support in the kernel.

Subject: bpf, selftests: fix handling of sparse CPU allocations

Previously, bpf_num_possible_cpus() had a bug when calculating a
number of possible CPUs in the case of sparse CPU allocations, as
it was considering only the first range or element of
/sys/devices/system/cpu/possible.

E.g. in the case of "0,2-3" (CPU 1 is not available), the function
returned 1 instead of 3.

This patch fixes the function by making it parse all CPU ranges and
elements.

From ba72a7b4badbf4dd3c49c585c3c662bacc54f46e Mon Sep 17 00:00:00 2001
From: Alexei Starovoitov <ast@kernel.org>
Date: Thu, 31 Jan 2019 15:40:12 -0800
Subject: selftests/bpf: test for BPF_F_LOCK

Add C based test that runs 4 bpf programs in parallel
that update the same hash and array maps.
And another 2 threads that read from these two maps
via lookup(key, value, BPF_F_LOCK) api
to make sure the user space sees consistent value in both
hash and array elements while user space races with kernel bpf progs.

Subject: selftests: forwarding: mirror_lib: Update ping limits

The current ping intervals are too short for running mirroring tests in
simulator. This leads to ping sending a follow-up ping before the reply
arrives, thus sending more than the requested 10 ICMP requests. Those
are mirrored, and over a certain threshold the test case run is
considered a failure, because too much traffic is observed.

Bump interval and timeout numbers 5x in mirroring tests to address the
spurious failures.

Subject: selftests: forwarding: mirror_gre_changes: Fix TTL test

When running in a simulator, the TTL change takes a while to settle and
during this time the performance of the packet processing is lowered.
The resulting instability leads to ping sending more packets as it
assumes some have been dropped. This then leads to regular spurious
failures as more packets than expected are observed.

Sleep a bit to give the system time to stabilize.

Subject: selftests: forwarding: mirror_lib: Wait for tardy mirrored packets

When running in an environment with poor performance (such as a
simulator), processing mirrored packets can take a while. Evaluating the
condition too soon leads to spurious "seen 9, expected 10" failures as
the last packet doesn't have enough time to get mirrored and the mirror
to arrive and bump the observed counters.

Wait for one ping interval before evaluating the test.

Subject: selftests: forwarding: mirror_gre_vlan_bridge_1q: Fix untagged test

The untagged egress test sets up mirroring to {,ip6}gretap such that the
underlay goes through a bridge. Then VLAN flags are manipulated to test
that the traffic leaves the bridge 802.1q-tagged or not, as appropriate.

However, when a neighbor expires at the time that the bridge VLAN is
configured as PVID and egress untagged, the following discovery process
can't finish, because the IP address on H3 is still at the VLAN-tagged
netdevice. This manifests by occasional failures where only several of
the 10 required packets get through.

Therefore, when reconfiguring the VLAN flags, move the IP address to the
appropriate device in the H3 VRF.

In addition to that, take this opportunity to embed an ASCII art diagram
to make the topology move obvious.

Subject: selftests: forwarding: mirror_gre_vlan_bridge_1q: Fix roaming test

ARP or ND traffic can cause spurious migration of FDB back to $swp3.
Mirroring is then updated in accordance with the change, and mirrored
packets are seen at h3, causing a failure.

Detect the case of this spurious roaming, and retry the test.

Subject: selftests: forwarding: mirror_gre_bridge_1q_lag: Flush neighbors

After one LAG slave is downed and another upped, it takes a while for
the neighbor on a bridge to time out and get renegotiated. The test does
prompt update of FDB entries by arpinging. But because the neighbor
still references another address, offloading is not possible, and some
packets may end up not being mirrored.

To force the neighbor renegotiation, simply flush the neighbor table at
the bridge.

Subject: selftests: forwarding: mirror_gre_flower: Fix test result handling

The global variable RET needs to be initialized before each call to
log_test. This test case sets it once before running the tests, but then
calls log_tests for every individual test. Thus a failure in one of the
tests causes spurious failures in follow-up tests as well.

Fix by moving the initialization of RET from test_all() to
full_test_span_gre_dir_acl(), a function that implements the test.

Subject: tools/bpf: simplify libbpf API function libbpf_set_print()

Currently, the libbpf API function libbpf_set_print()
takes three function pointer parameters for warning, info
and debug printout respectively.

This patch changes the API to have just one function pointer
parameter and the function pointer has one additional
parameter "debugging level". So if in the future, if
the debug level is increased, the function signature
won't change.

Bind and connect to localhost. There is no reason for this test to
use non-localhost interface. This lets us run this test in a network
namespace.

Subject: libbpf: fix libbpf_print

With the recent print rework we now have the following problem:
pr_{warning,info,debug} expand to __pr which calls libbpf_print.
libbpf_print does va_start and calls __libbpf_pr with va_list argument.
In __base_pr we again do va_start. Because the next argument is a
va_list, we don't get correct pointer to the argument (and print noting
in my case, I don't know why it doesn't crash tbh).

Fix this by changing libbpf_print_fn_t signature to accept va_list and
remove unneeded calls to va_start in the existing users.

Alternatively, this can we solved by exporting __libbpf_pr and
changing __pr macro to (and killing libbpf_print):
{
	if (__libbpf_pr)
		__libbpf_pr(level, "libbpf: " fmt, ##__VA_ARGS__)
}

Subject: selftests/btf: add initial BTF dedup tests

This patch sets up a new kind of tests (BTF dedup tests) and tests few aspects of
BTF dedup algorithm. More complete set of tests will come in follow up patches.

From e2c6f50e48849298bed694de03cceb537d95cdc4 Mon Sep 17 00:00:00 2001
From: Björn Töpel <bjorn.topel@gmail.com>

Subject: selftests/bpf: add "any alignment" annotation for some tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RISC-V does, in-general, not have "efficient unaligned access". When
testing the RISC-V BPF JIT, some selftests failed in the verification
due to misaligned access. Annotate these tests with the
F_NEEDS_EFFICIENT_UNALIGNED_ACCESS flag.

Subject: tools/bpf: fix a selftest test_btf failure

Commit 9c651127445c ("selftests/btf: add initial BTF dedup tests")
added dedup tests in test_btf.c.
It broke the raw test:
 BTF raw test[71] (func proto (Bad arg name_off)):
    btf_raw_create:2905:FAIL Error getting string #65535, strs_cnt:1

The test itself encodes invalid func_proto parameter name
offset 0xffffFFFF as a negative test for the kernel.
The above commit changed the meaning of that offset and
resulted in a user space error.
  #define NAME_NTH(N) (0xffff0000 | N)
  #define IS_NAME_NTH(X) ((X & 0xffff0000) == 0xffff0000)
  #define GET_NAME_NTH_IDX(X) (X & 0x0000ffff)

Currently, the kernel permits maximum name offset 0xffff.
Set the test name off as 0x0fffFFFF to trigger the kernel
verification failure.

Subject: bpf: test_maps: fix possible out of bound access warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When compiling test_maps selftest with GCC-8, it warns that an array
might be indexed with a negative value, which could cause a negative
out of bound access, depending on parameters of the function. This
is the GCC-8 warning:

	gcc -Wall -O2 -I../../../include/uapi -I../../../lib -I../../../lib/bpf -I../../../../include/generated -DHAVE_GENHDR -I../../../include    test_maps.c /home/breno/Devel/linux/tools/testing/selftests/bpf/libbpf.a -lcap -lelf -lrt -lpthread -o /home/breno/Devel/linux/tools/testing/selftests/bpf/test_maps
	In file included from test_maps.c:16:
	test_maps.c: In function ‘run_all_tests’:
	test_maps.c:1079:10: warning: array subscript -1 is below array bounds of ‘pid_t[<Ube20> + 1]’ [-Warray-bounds]
	   assert(waitpid(pid[i], &status, 0) == pid[i]);
		  ^~~~~~~~~~~~~~~~~~~~~~~~~~~
	test_maps.c:1059:6: warning: array subscript -1 is below array bounds of ‘pid_t[<Ube20> + 1]’ [-Warray-bounds]
	   pid[i] = fork();
	   ~~~^~~

This patch simply guarantees that the task(s) variables are unsigned,
thus, they could never be a negative number (which they are not in
current code anyway), hence avoiding an out of bound access warning.

Subject: selftests: mlxsw: Add a test for blackhole routes

Use a simple topology consisting of two hosts directly connected to a
router. Make sure IPv4/IPv6 ping works and then add blackhole routes.
Test that ping fails and that the routes are marked as offloaded. Use a
simple tc filter to test that packets were dropped by the ASIC and not
trapped to the CPU.

Subject: tools/bpf: add log_level to bpf_load_program_attr

The kernel verifier has three levels of logs:
    0: no logs
    1: logs mostly useful
  > 1: verbose

Current libbpf API functions bpf_load_program_xattr() and
bpf_load_program() cannot specify log_level.
The bcc, however, provides an interface for user to
specify log_level 2 for verbose output.

This patch added log_level into structure
bpf_load_program_attr, so users, including bcc, can use
bpf_load_program_xattr() to change log_level. The
supported log_level is 0, 1, and 2.

The bpf selftest test_sock.c is modified to enable log_level = 2.
If the "verbose" in test_sock.c is changed to true,
the test will output logs like below:
  $ ./test_sock
  func#0 @0
  0: R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1
  0: (bf) r6 = r1
  1: R1=ctx(id=0,off=0,imm=0) R6_w=ctx(id=0,off=0,imm=0) R10=fp0,call_-1
  1: (61) r7 = *(u32 *)(r6 +28)
  invalid bpf_context access off=28 size=4

  Test case: bind4 load with invalid access: src_ip6 .. [PASS]
  ...
  Test case: bind6 allow all .. [PASS]
  Summary: 16 PASSED, 0 FAILED

Some test_sock tests are negative tests and verbose verifier
log will be printed out as shown in the above.

Subject: Revert "selftests: firmware: add
 CONFIG_FW_LOADER_USER_HELPER_FALLBACK to config"

This reverts commit 7492902e8d22b568463897fa967c0886764cf034.

The commit tried to address an issue discovered by Dan where he got
a message saying:

'usermode helper disabled so ignoring test'.

Dans's commit is forcing CONFIG_FW_LOADER_USER_HELPER_FALLBACK but just
having CONFIG_FW_LOADER_USER_HELPER suffices to emulate the_FALLBACK
functionality.

Dan's commit is trying to fix an issue which is hidden from a previous
commit. That issue will be addressed properly next.

Subject: Revert "selftests: firmware: remove use of non-standard diff -Z
 option"

This reverts commit f70b472e937bb659a7b7a14e64f07308e230888c.

This breaks testing on Debian, and this patch was NACKed anyway.
The proper way to address this is a quirk for busybox as that is
where the issue is present.

Subject: selftests: firmware: fix verify_reqs() return value

commit a6a9be9270c87 ("selftests: firmware: return Kselftest Skip code
for skipped tests") by Shuah modified failures to return the special
error code of $ksft_skip (4). We have a corner case issue where we
*do* want to verify_reqs().

Subject: tools/bpf: remove btf__get_strings() superseded by raw data API

Now that we have btf__get_raw_data() it's trivial for tests to iterate
over all strings for testing purposes, which eliminates the need for
btf__get_strings() API.

Subject: bpf: Add skb->sk, bpf_sk_fullsock and bpf_tcp_sock tests to
 test_verifer

This patch tests accessing the skb->sk and the new helpers,
bpf_sk_fullsock and bpf_tcp_sock.

The errstr of some existing "reference tracking" tests is changed
with s/bpf_sock/sock/ and s/socket/sock/ where "sock" is from the
verifier's reg_type_str[].

Subject: selftests: bpf: add "alu32" to .gitignore

"alu32" is a build dir and contains various files for BPF sub-register
code-gen testing.

This patch tells git to ignore it.

Subject: selftests: bpf: extend sub-register mode compilation to all bpf
 object files

At the moment, we only do extra sub-register mode compilation on bpf object
files used by "test_progs". These object files are really loaded and
executed.

This patch further extends sub-register mode compilation to all bpf object
files, even those without corresponding runtime tests. Because this could
help testing LLVM sub-register code-gen, kernel bpf selftest has much more
C testcases with reasonable size and complexity compared with LLVM
testsuite which only contains unit tests.

There were some file duplication inside BPF_OBJ_FILES_DUAL_COMPILE which
is removed now.

Subject: selftests: bpf: centre kernel bpf objects under new subdir "progs"

At the moment, all kernel bpf objects are listed under BPF_OBJ_FILES.
Listing them manually sometimes causing patch conflict when people are
adding new testcases simultaneously.

It is better to centre all the related source files under a subdir
"progs", then auto-generate the object file list.

Subject: selftests: bpf: relax sub-register mode compilation criteria

Sub-register mode compilation was enabled only when there are eBPF "v3"
processor supports at both compilation time inside LLVM and runtime inside
kernel.

Given separation betwen build and test server could be often, this patch
removes the runtime support criteria.

Subject: livepatch/selftests: use "$@" to preserve argument list

The livepatch selftest functions.sh library uses "$*" and an
intermediate variable to extract and then pass arguments from function
to function call.  The effect of this combination is that the argument
list is flattened into a single argument.  Sometimes this is benign, but
in cases like __load_mod(), the modprobe invocation will interpret all
the module parameters as a single parameter.

Drop the intermediate variable and use the "$@" special parameter as
described in the bash manual.

Subject: LSM: SafeSetID: add selftest

This patch adds a selftest for the SafeSetID LSM. The test requires
mounting securityfs if it isn't mounted, creating test users in
/etc/passwd, and configuring policies for the SafeSetID LSM through
writes to securityfs.

Subject: selftests: don't kill child immediately in get_metadata() test

This this test forks a child, and then the parent waits for a write() to a
pipe signalling the child is ready to be attached to. If something in the
child ASSERTs before it does this write, the test will hang waiting for it.
Instead, let's EXPECT, so that execution continues until we do the write.
Any failure after that is fine and can ASSERT.

While playing around with a way to skip the seccomp get_metadata test, I
noticed that this header uses printf() without defining it, leading to,

../kselftest.h: In function ‘ksft_print_header’:
../kselftest.h:61:3: warning: implicit declaration of function ‘printf’ [-Wimplicit-function-declaration]

if user code doesn't also use printf.

Subject: selftests: skip seccomp get_metadata test if not real root

The get_metadata() test requires real root, so let's skip it if we're not
real root.

Note that I used XFAIL here because that's what the test does later if
CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled. After looking at the
code, there doesn't seem to be a nice way to skip tests defined as TEST(),
since there's no return code (I tried exit(KSFT_SKIP), but that didn't work
either...). So let's do it this way to be consistent, and easier to fix
when someone comes along and fixes it.

Subject: selftests: set NO_NEW_PRIVS bit in seccomp user tests

seccomp() doesn't allow users who aren't root in their userns to attach
filters unless they have the nnp bit set, so let's set it so that these
tests can pass when run as an unprivileged user.

This idea stolen from the other seccomp tests, which use this trick :)

Subject: selftests: unshare userns in seccomp pidns testcases

The pid ns cannot be unshare()d as an unprivileged user without owning the
userns as well. Let's unshare the userns so that we can subsequently
unshare the pidns.

This also means that we don't need to set the no new privs bit as in the
other test cases, since we're unsharing the userns.

Date: Wed, 13 Feb 2019 11:53:41 -0800
Subject: selftests: bpf: add test_lwt_ip_encap selftest

This patch adds a bpf self-test to cover BPF_LWT_ENCAP_IP mode
in bpf_lwt_push_encap.

Covered:
- encapping in LWT_IN and LWT_XMIT
- IPv4 and IPv6

A follow-up patch will add GSO and VRF-enabled tests.

Subject: selftests: fix timestamping Makefile

The clean target in the makefile conflicts with the generic
kselftests lib.mk, and fails to properly remove the compiled
test programs.

Remove the redundant rule, the TEST_GEN_FILES will be already
removed by the CLEAN macro in lib.mk.

Subject: selftests: forwarding: Add some missing configuration symbols

For the forwarding selftests to work, we need network namespaces when
using veth/vrf otherwise ping/ping6 commands like these:

ip vrf exec vveth0 /bin/ping 192.0.2.2 -c 10 -i 0.1 -w 5

will fail because network namespaces may not be enabled.

Subject: selftests: bpf: test_lwt_ip_encap: add negative tests.

As requested by David Ahern:

- add negative tests (no routes, explicitly unreachable destinations)
  to exercize error handling code paths;
- do not exit on test failures, but instead print a summary of
  passed/failed tests at the end.

Future patches will add TSO and VRF tests.

Subject: bpf, lpm: fix lookup bug in map_delete_elem

trie_delete_elem() was deleting an entry even though it was not matching
if the prefixlen was correct. This patch adds a check on matchlen.

Reproducer:

$ sudo bpftool map create /sys/fs/bpf/mylpm type lpm_trie key 8 value 1 entries 128 name mylpm flags 1
$ sudo bpftool map update pinned /sys/fs/bpf/mylpm key hex 10 00 00 00 aa bb cc dd value hex 01
$ sudo bpftool map dump pinned /sys/fs/bpf/mylpm
key: 10 00 00 00 aa bb cc dd  value: 01
Found 1 element
$ sudo bpftool map delete pinned /sys/fs/bpf/mylpm key hex 10 00 00 00 ff ff ff ff
$ echo $?
0
$ sudo bpftool map dump pinned /sys/fs/bpf/mylpm
Found 0 elements

A similar reproducer is added in the selftests.

Without the patch:

$ sudo ./tools/testing/selftests/bpf/test_lpm_map
test_lpm_map: test_lpm_map.c:485: test_lpm_delete: Assertion `bpf_map_delete_elem(map_fd, key) == -1 && errno == ENOENT' failed.
Aborted

With the patch: test_lpm_map runs without errors.

Subject: selftests: fib_tests: sleep after changing carrier. again.

Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.

There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.

Sleeping on the second set of tests make the failures go away.

Subject: selftests: tdc_batch.py: add options needed for concurrency tests

Extend tdc_batch.py with several optional CLI arguments that are used for
implementation of concurrency tests in following patches in this set:

- Add optional argument to specify range of filter handles used in batch
  file [fitler_handle, filter_handle+number). This is needed for testing
  filter deletion where it is necessary to know exact handles of configured
  filters.

- Add optional argument to specify filter operation type (possible values
  are ['add', 'del', 'replace']) instead of hardcoded "add" value. This
  allows generation of batches for filter addition, deletion and
  replacement.

- Add optional argument to allow user to change mac address prefix that is
  used for all filters in batch. This is necessary to allow generating
  multiple batches with unique flower classifier keys.

Subject: selftests: concurrency: add test to verify parallel rules insertion

Implement test that verifies parallel rules insertion by adding 1 million
flower filters with 10 concurrent tc instances. Put it to standalone
'concurrency' category.

Implement tdc_multibatch.py helper script that is used to generate multiple
batch files for concurrent tc execution. Extend config with new 'BATCH_DIR'
variable to specify temporary output directory that is used to store batch
files generated by tdc_multibatch.py.

Subject: selftests: concurrency: add test to verify concurrent delete

Implement test that verifies concurrent deletion of rules by executing 10
tc instances that delete flower filters in same handle range. In this case
only one tc instance succeeds in deleting a filter with particular handle.
To mitigate expected failures of all other instances, run tc with 'force'
option to continue processing batch file in case of errors and expect xargs
to return code '123' that indicates that invocation of command(s) exited
with error in range 1-125.

Subject: selftests: concurrency: add test to verify parallel add/delete

Implement test that runs 5 instances of tc add filter in parallel with 5
instances of tc del filter from same tp instance. Each instance uses its
own filter handle and key range.

Extend tdc_multibatch.py with additional options required to implement the
test: common prefix for all generated batch files, first value of filter
handle range, MAC address prefix modifier. These are necessary to allow
creating batch files with unique keys and handle ranges with multiple
invocation of tdc_multibatch.py helper script.

Subject: selftests: concurrency: add test to verify parallel replace/delete

Implement test that runs 5 instances of tc replace filter in parallel with
5 instances of tc del filter from same tp instance. Each instance uses its
own filter handle and key range.

Subject: selftests/bpf: make sure signal interrupts BPF_PROG_TEST_RUN

Simple test that I used to reproduce the issue in the previous commit:
Do BPF_PROG_TEST_RUN with max iterations, each program is 4096 simple
move instructions. File alarm in 0.1 second and check that
bpf_prog_test_run is interrupted (i.e. test doesn't hang).

Note: reposting this for bpf-next to avoid linux-next conflict. In this
version I test both BPF_PROG_TYPE_SOCKET_FILTER (which uses generic
bpf_test_run implementation) and BPF_PROG_TYPE_FLOW_DISSECTOR (which has
it own loop with preempt handling in bpf_prog_test_run_flow_dissector).

Subject: netfilter: nat: merge nf_nat_ipv4,6 into nat core

before:
   text    data     bss     dec     hex filename
  16566    1576    4136   22278    5706 nf_nat.ko
   3598	    844	      0	   4442	   115a	nf_nat_ipv6.ko
   3187	    844	      0	   4031	    fbf	nf_nat_ipv4.ko

after:
   text    data     bss     dec     hex filename
  22948    1612    4136   28696    7018 nf_nat.ko

... with ipv4/v6 nat now provided directly via nf_nat.ko.

Also changes:
       ret = nf_nat_ipv4_fn(priv, skb, state);
       if (ret != NF_DROP && ret != NF_STOLEN &&
into
	if (ret != NF_ACCEPT)
		return ret;

everywhere.

The nat hooks never should return anything other than
ACCEPT or DROP (and the latter only in rare error cases).

The original code uses multi-line ANDing including assignment-in-if:
        if (ret != NF_DROP && ret != NF_STOLEN &&
           !(IPCB(skb)->flags & IPSKB_XFRM_TRANSFORMED) &&
            (ct = nf_ct_get(skb, &ctinfo)) != NULL) {

I removed this while moving, breaking those in separate conditionals
and moving the assignments into extra lines.

checkpatch still generates some warnings:
 1. Overly long lines (of moved code).
    Breaking them is even more ugly. so I kept this as-is.
 2. use of extern function declarations in a .c file.
    This is necessary evil, we must call
    nf_nat_l3proto_register() from the nat core now.
    All l3proto related functions are removed later in this series,
    those prototypes are then removed as well.

v2: keep empty nf_nat_ipv6_csum_update stub for CONFIG_IPV6=n case.
v3: remove IS_ENABLED(NF_NAT_IPV4/6) tests, NF_NAT_IPVx toggles
    are removed here.
v4: also get rid of the assignments in conditionals.

Subject: tools/bpf: selftests: add map lookup to test_map_in_map bpf prog

The bpf_map_lookup_elem is added in the bpf program.
Without previous patch, the test change will trigger the
following error:
  $ ./test_maps
  ...
  ; value_p = bpf_map_lookup_elem(map, &key);
  20: (bf) r1 = r7
  21: (bf) r2 = r8
  22: (85) call bpf_map_lookup_elem#1
  ; if (!value_p || *value_p != 123)
  23: (15) if r0 == 0x0 goto pc+16
   R0=map_value(id=2,off=0,ks=4,vs=4,imm=0) R6=inv1 R7=map_ptr(id=0,off=0,ks=4,vs=4,imm=0)
   R8=fp-8,call_-1 R10=fp0,call_-1 fp-8=mmmmmmmm
  ; if (!value_p || *value_p != 123)
  24: (61) r1 = *(u32 *)(r0 +0)
   R0=map_value(id=2,off=0,ks=4,vs=4,imm=0) R6=inv1 R7=map_ptr(id=0,off=0,ks=4,vs=4,imm=0)
   R8=fp-8,call_-1 R10=fp0,call_-1 fp-8=mmmmmmmm
  bpf_spin_lock cannot be accessed directly by load/store

With the kernel fix in the previous commit, the error goes away.

Subject: selftests: pmtu: disable DAD in all namespaces

Otherwise, the configured IPv6 address could be still "tentative"
at test time, possibly causing tests failures.
We can also drop some sleep along the code and decrease the
timeout for most commands so that the test runtime decreases.

v1 -> v2:
 - fix comment (Stefano)

From: Paolo Abeni <pabeni@redhat.com>
Date: Mon, 25 Feb 2019 16:08:37 +0100
Subject: selftests: pmtu: add explicit tests for PMTU exceptions cleanup

Add a couple of new tests, explicitly checking that the kernel
timely releases PMTU exceptions on related device removal.
This is mostly a regression test vs the issue fixed by
commit f5b51fe804ec ("ipv6: route: purge exception on removal")

Only 2 new test cases have been added, instead of extending all
the existing ones, because the reproducer requires executing
several commands and would slow down too much the tests otherwise.

v2 -> v3:
 - more cleanup, still from Stefano

v1 -> v2:
 - several script cleanups, as suggested by Stefano

Subject: selftests: rtnetlink: use internal netns switch for ip commands

'ip' can switch network namespaces internally and then run a given
command relative to that namespace without the need to fork and exec
another ip instance. Update all references of the form:
    ip netns exec "$testns" ip ...
to
    ip -netns "$testns" ...

Subject: selftests/bpf: use __bpf_constant_htons in test_prog.c for flow
 dissector

Older GCC (<4.8) isn't smart enough to optimize !__builtin_constant_p()
branch in bpf_htons.

I recently fixed it for pkt_v4 and pkt_v6 in commit a0517a0f7ef23
("selftests/bpf: use __bpf_constant_htons in test_prog.c"), but
later added another bunch of bpf_htons in commit bf0f0fd939451
("selftests/bpf: add simple BPF_PROG_TEST_RUN examples for flow
dissector").

Fixes: bf0f0fd939451 ("selftests/bpf: add simple BPF_PROG_TEST_RUN examples for flow dissector")

Subject: tools: libbpf: add a correctly named define for map iteration

For historical reasons the helper to loop over maps in an object
is called bpf_map__for_each while it really should be called
bpf_object__for_each_map.  Rename and add a correctly named
define for backward compatibility.

Switch all in-tree users to the correct name (Quentin).

Subject: selftests/bpf: add btf_dedup test of FWD/STRUCT resolution

This patch adds a btf_dedup test exercising logic of STRUCT<->FWD
resolution and validating that STRUCT is not resolved to a FWD. It also
forces hash collisions, forcing both FWD and STRUCT to be candidates for
each other. Previously this condition caused infinite loop due to FWD
pointing to STRUCT and STRUCT pointing to its FWD.

Subject: selftests: fixes for UDP GRO

The current implementation for UDP GRO tests is racy: the receiver
may flush the RX queue while the sending is still transmitting and
incorrectly report RX errors, with a wrong number of packet received.

Add explicit timeouts to the receiver for both connection activation
(first packet received for UDP) and reception completion, so that
in the above critical scenario the receiver will wait for the
transfer completion.

Subject: tc-testing: Allow test cases to be skipped

By adding a check for an optional key/value pair to the test case
data, individual test cases may be skipped to prevent tdc from
aborting a test run due to setup or teardown failure.

If a test case is skipped, it will still appear in the results
output to allow for a consistent number of executed tests in each
run. However, the test will be marked as skipped.

This support for skipping extends to any plugins that may generate
additional results for each executed test.

Date: Fri, 1 Mar 2019 19:42:13 -0800
Subject: selftests: bpf: break up test_progs - preparations

Add new prog_tests directory where tests are supposed to land.
Each prog_tests/<filename>.c is expected to have a global function
with signature 'void test_<filename>(void)'. Makefile automatically
generates prog_tests/tests.h file with entry for each prog_tests file:

	#ifdef DECLARE
	extern void test_<filename>(void);
	...
	#endif

	#ifdef CALL
	test_<filename>();
	...
	#endif

prog_tests/tests.h is included in test_progs.c in two places with
appropriate defines. This scheme allows us to move each function with
a separate patch without breaking anything.

Compared to the recent verifier split, each separate file here is
a compilation unit and test_progs.[ch] is now used as a place to put
some common routines that might be used by multiple tests.

Subject: selftests: add tests for pidfd_send_signal()

As suggested by Andrew Morton in [1] add selftests for the new
sys_pidfd_send_signal() syscall:

/* test_pidfd_send_signal_syscall_support */
Test whether the pidfd_send_signal() syscall is supported and the tests can
be run or need to be skipped.

/* test_pidfd_send_signal_simple_success */
Test whether sending a signal via a pidfd works.

/* test_pidfd_send_signal_exited_fail */
Verify that sending a signal to an already exited process fails with ESRCH.

/* test_pidfd_send_signal_recycled_pid_fail */
Verify that a recycled pid cannot be signaled via a pidfd referring to an
already exited process that had the same pid (cf. [2], [3]).

Subject: selftests/vm: add script helper for CONFIG_TEST_VMALLOC_MODULE

Add the test script for the kernel test driver to analyse vmalloc
allocator for benchmarking and stressing purposes.  It is just a kernel
module loader.  You can specify and pass different parameters in order
to investigate allocations behaviour.  See "usage" output for more
details.

Also add basic vmalloc smoke test to the "run_vmtests" suite.

Subject: proc: test /proc/*/maps, smaps, smaps_rollup, statm

Start testing VM related fiels found in per-process files.

Do it by jiting small executable which brings its address space to
precisely known state, then comparing /proc/*/maps, smaps, smaps_rollup,
and statm files to expected values.

Currently only x86_64 is supported.

[adobriyan@gmail.com: exit correctly in /proc/*/maps test]

Subject: selftests/bpf: test that GSO works in lwt_ip_encap

Add a test on egress that a large TCP packet successfully goes through
the lwt+bpf encap tunnel.

Although there is no direct evidence that GSO worked, as opposed to
e.g. TCP segmentation or IP fragmentation (maybe a kernel stats counter
should be added to track the number of failed GSO attempts?), without
the previous patch in the patchset this test fails, and printk-debugging
showed that software-based GSO succeeded here (veth is not compatible with
SKB_GSO_DODGY, so GSO happens in the software stack).

Also removed an unnecessary nodad and added a missed failed flag.

Subject: selftests: bpf: fix compilation with out-of-tree $(OUTPUT)

A bunch of related changes lumped together:
* Create prog_tests and verifier output directories; these don't exist with
  out-of-tree $(OUTPUT)
* Add missing -I (via separate TEST_{PROGS,VERIFIER}_CFLAGS) for the main tree
  ($(PWD) != $(OUTPUT) for out-of-tree)
* Add libbpf.a dependency for test_progs_32 (parallel make fails otherwise)
* Add missing "; \" after "cd" when generating test.h headers

Tested by:
$ alias m="make -s -j$(nproc)"
$ m -C tools/testing/selftests/bpf/ clean
$ m -C tools/lib/bpf/ clean
$ rm -rf xxx; mkdir xxx; m -C tools/testing/selftests/bpf/ OUTPUT=$PWD/xxx
$ m -C tools/testing/selftests/bpf/

CHECK macro implicitly uses duration. We call CHECK() a couple of times
before duration is initialized from bpf_prog_test_run().
Explicitly set duration to 0 to avoid compiler warnings.

Subject: bpf: fix replace_map_fd_with_map_ptr's ldimm64 second imm field

Non-zero imm value in the second part of the ldimm64 instruction for
BPF_PSEUDO_MAP_FD is invalid, and thus must be rejected. The map fd
only ever sits in the first instructions' imm field. None of the BPF
loaders known to us are using it, so risk of regression is minimal.
For clarity and consistency, the few insn->{src_reg,imm} occurrences
are rewritten into insn[0].{src_reg,imm}. Add a test case to the BPF
selftest suite as well.

Subject: tools: mark 'test_vmalloc.sh' executable

Several of these scripts have come in as old-fashioned patches, and in
the process lost the executable bit.  In most cases it doesn't matter,
since the test infrastructure will explicitly execute them using the
proper shell interpreter, but at least in the case of the new vmalloc
test, the lack of execurable bit caused the test to fail with

    ./run_vmtests: line 217: ./test_vmalloc.sh: Permission denied

because of the lacking exectuable permissions bit.

This patch fixes that up.

NOTE! A simple script to look for non-executable scripts in the kernel,
something like

    git ls-files --stage -- '*.sh' |
        grep 100644 |
        cut -f2 |
        xargs grep -l '#!'

will show that there's a lot of other files that _look_ like executable
shell scripts, but don't have the executable bit set.  I considered just
scripting them all to be executable, but since it looks like the common
pattern is to not really require it, I'm just doing the minimal fix as
pointed out by the kernel test robot.

Subject: tools/testing/selftests/sysctl/sysctl.sh: add tests for >32-bit
 values written to 32-bit integers

Patch series "sysctl: fix range-checking in do_proc_dointvec_minmax_conv()", v2.

After being left with an unusable system after a typo executing
something like 'echo $((1<<24)) > /proc/sys/vm/max_map_count', I found
that do_proc_dointvec_minmax_conv() was missing a check to ensure that
the converted value actually fits in an int.

The first of the following patches enhances the sysctl selftest such
that it detects this problem; the second provides a minimal fix
(suitable for -stable) such that the selftest passes.  The third patch
then performs a more thorough refactoring to eliminate the code
duplication that led to the bug in the first place (maintaining the
passing status of the selftest).

This patch (of 3):

At present this exposes a bug in do_proc_dointvec_minmax_conv() (it
fails to check for values that are too wide to fit in an int).

Subject: selftests/bpf: fix segfault of test_progs when prog loading failed

The test_progs subtests, test_spin_lock() and test_map_lock(),
requires BTF present to run successfully.
Currently, when BTF failed to load, test_progs will segfault,
  $ ./test_progs
  ...
  12: (bf) r1 = r8
  13: (85) call bpf_spin_lock#93
  map 'hash_map' has to have BTF in order to use bpf_spin_lock

  libbpf: -- END LOG --
  libbpf: failed to load program 'map_lock_demo'
  libbpf: failed to load object './test_map_lock.o'
  test_map_lock:bpf_prog_load errno 13
  Segmentation fault

The segfault is caused by uninitialized variable "obj", which
is used in bpf_object__close(obj), when bpf prog failed to load.

Initializing variable "obj" to NULL in two occasions fixed the problem.
  $ ./test_progs
  ...
  Summary: 219 PASSED, 2 FAILED

Fixes: b4d4556c3266 ("selftests/bpf: add bpf_spin_lock verifier tests")
Fixes: ba72a7b4badb ("selftests/bpf: test for BPF_F_LOCK")

Subject: bpf: Test ref release issue in bpf_tcp_sock and bpf_sk_fullsock

Adding verifier tests to ensure the ptr returned from bpf_tcp_sock() and
bpf_sk_fullsock() cannot be accessed after bpf_sk_release() is called.
A few of the tests are derived from a reproducer test by Lorenz Bauer.

the following script:

 # tc actions replace action bpf \
 > bytecode '1,6 0 0 4294967295' goto chain 42 index 90 cookie c1a0c1a0

Subject: net/sched: act_ife: validate the control action inside init()

the following script:

 # tc qdisc add dev crash0 clsact
 # tc filter add dev crash0 egress matchall \
 > action ife encode allow mark pass index 90
 # tc actions replace action ife \
 > encode allow mark goto chain 42 index 90 cookie c1a0c1a0
 # tc action show action ife

had the following output:

 IFE type 0xED3E
 IFE type 0xED3E
 Error: Failed to init TC action chain.

         cookie c1a0c1a0

Then, the first packet transmitted by crash0 made the kernel crash:

Validating the control action within tcf_mirred_init() proved to fix the
above issue. For the same reason, postpone the assignment of tcfa_action
and tcfm_eaction to avoid partial reconfiguration of a mirred rule when
it's replaced by another one that mirrors to a device that does not
exist. A TDC selftest is added to verify the correct behavior.

Subject: net/sched: act_pedit: validate the control action inside init()

the following script:

 # tc filter add dev crash0 egress matchall \
 > action pedit ex munge ip ttl set 10 pass index 90
 # tc actions replace action pedit \
 > ex munge ip ttl set 10 goto chain 42 index 90 cookie c1a0c1a0
 # tc actions show action pedit

had the following output:

 Error: Failed to init TC action chain.
 We have an error talking to the kernel
 total acts 1

         action order 0:  pedit action goto chain 42 keys 1
          index 90 ref 2 bind 1
          key #0  at ipv4+8: val 0a000000 mask 00ffffff
         cookie c1a0c1a0

Then, the first packet transmitted by crash0 made the kernel crash:

Subject: net/sched: act_sample: validate the control action inside init()

the following script:

 # tc qdisc add dev crash0 clsact
 # tc filter add dev crash0 egress matchall \
 > action sample rate 1024 group 4 pass index 90
 # tc actions replace action sample \
 > rate 1024 group 4 goto chain 42 index 90 cookie c1a0c1a0
 # tc actions show action sample

had the following output:

Then, the first packet transmitted by crash0 made the kernel crash:

Subject: net/sched: act_tunnel_key: validate the control action inside init()

the following script:

 # tc qdisc add dev crash0 clsact
 # tc filter add dev crash0 egress matchall \
 > action tunnel_key set src_ip 10.10.10.1 dst_ip 20.20.2 dst_port 3128 \
 > nocsum id 1 pass index 90
 # tc actions replace action tunnel_key \
 > set src_ip 10.10.10.1 dst_ip 20.20.2 dst_port 3128 nocsum id 1 \
 > goto chain 42 index 90 cookie c1a0c1a0
 # tc actions show action tunnel_key

had the following output:

 Error: Failed to init TC action chain.
 We have an error talking to the kernel
 total acts 1

         action order 0: tunnel_key  set
         src_ip 10.10.10.1
         dst_ip 20.20.2.0
         key_id 1
         dst_port 3128
         nocsum goto chain 42
          index 90 ref 2 bind 1
         cookie c1a0c1a0

then, the first packet transmitted by crash0 made the kernel crash:

Subject: net/sched: act_vlan: validate the control action inside init()

the following script:

 # tc qdisc add dev crash0 clsact
 # tc filter add dev crash0 egress matchall \
 > action vlan pop pass index 90
 # tc actions replace action vlan \
 > pop goto chain 42 index 90 cookie c1a0c1a0
 # tc actions show action vlan

had the following output:

 Error: Failed to init TC action chain.
 We have an error talking to the kernel

Subject: bpf: verifier: propagate liveness on all frames

Commit 7640ead93924 ("bpf: verifier: make sure callees don't prune
with caller differences") connected up parentage chains of all
frames of the stack.  It didn't, however, ensure propagate_liveness()
propagates all liveness information along those chains.

This means pruning happening in the callee may generate explored
states with incomplete liveness for the chains in lower frames
of the stack.

The included selftest is similar to the prior one from commit
7640ead93924 ("bpf: verifier: make sure callees don't prune with
caller differences"), where callee would prune regardless of the
difference in r8 state.

Now we also initialize r9 to 0 or 1 based on a result from get_random().
r9 is never read so the walk with r9 = 0 gets pruned (correctly) after
the walk with r9 = 1 completes.

The selftest is so arranged that the pruning will happen in the
callee.  Since callee does not propagate read marks of r8, the
explored state at the pruning point prior to the callee will
now ignore r8.

Propagate liveness on all frames of the stack when pruning.

This patch adds specific test exposing bug in btf_dedup_is_equiv() when
comparing candidate VOID type to a non-VOID canonical type. It's
important for canonical type to be anonymous, otherwise name equality
check will do the right thing and will exit early.

Subject: KVM: selftests: assert on exit reason in CR4/cpuid sync test

...so that the test doesn't end up in an infinite loop if it fails for
whatever reason, e.g. SHUTDOWN due to gcc inserting stack canary code
into ucall() and attempting to derefence a null segment.

Subject: KVM: selftests: explicitly disable PIE for tests

KVM selftests embed the guest "image" as a function in the test itself
and extract the guest code at runtime by manually parsing the elf
headers.  The parsing is very simple and doesn't supporting fancy things
like position independent executables.  Recent versions of gcc enable
pie by default, which results in triple fault shutdowns in the guest due
to the virtual address in the headers not matching up with the virtual
address retrieved from the function pointer.

Subject: KVM: selftests: disable stack protector for all KVM tests

Since 4.8.3, gcc has enabled -fstack-protector by default.  This is
problematic for the KVM selftests as they do not configure fs or gs
segments (the stack canary is pulled from fs:0x28).  With the default
behavior, gcc will insert a stack canary on any function that creates
buffers of 8 bytes or more.  As a result, ucall() will hit a triple
fault shutdown due to reading a bad fs segment when inserting its
stack canary, i.e. every test fails with an unexpected SHUTDOWN.

Subject: KVM: selftests: complete IO before migrating guest state

Documentation/virtual/kvm/api.txt states:

  NOTE: For KVM_EXIT_IO, KVM_EXIT_MMIO, KVM_EXIT_OSI, KVM_EXIT_PAPR and
        KVM_EXIT_EPR the corresponding operations are complete (and guest
        state is consistent) only after userspace has re-entered the
        kernel with KVM_RUN.  The kernel side will first finish incomplete
        operations and then check for pending signals.  Userspace can
        re-enter the guest with an unmasked signal pending to complete
        pending operations.

Because guest state may be inconsistent, starting state migration after
an IO exit without first completing IO may result in test failures, e.g.
a proposed change to KVM's handling of %rip in its fast PIO handling[1]
will cause the new VM, i.e. the post-migration VM, to have its %rip set
to the IN instruction that triggered KVM_EXIT_IO, leading to a test
assertion due to a stage mismatch.

For simplicitly, require KVM_CAP_IMMEDIATE_EXIT to complete IO and skip
the test if it's not available.  The addition of KVM_CAP_IMMEDIATE_EXIT
predates the state selftest by more than a year.

Subject: libnvdimm/security: provide fix for secure-erase to use zero-key

Add a zero key in order to standardize hardware that want a key of 0's to
be passed. Some platforms defaults to a zero-key with security enabled
rather than allow the OS to enable the security. The zero key would allow
us to manage those platform as well. This also adds a fix to secure erase
so it can use the zero key to do crypto erase. Some other security commands
already use zero keys. This introduces a standard zero-key to allow
unification of semantics cross nvdimm security commands.

Subject: selftests/bpf: fix vlan handling in flow dissector program

When we tail call PROG(VLAN) from parse_eth_proto we don't need to peek
back to handle vlan proto because we didn't adjust nhoff/thoff yet. Use
flow_keys->n_proto, that we set in parse_eth_proto instead and
properly increment nhoff as well.

Also, always use skb->protocol and don't look at skb->vlan_present.
skb->vlan_present indicates that vlan information is stored out-of-band
in skb->vlan_{tci,proto} and vlan header is already pulled from skb.
That means, skb->vlan_present == true is not relevant for BPF flow
dissector.

Add simple test cases with VLAN tagged frames:
  * single vlan for ipv4
  * double vlan for ipv6

Subject: net/flow_dissector: pass flow_keys->n_proto to BPF programs

This is a preparation for the next commit that would prohibit access to
the most fields of __sk_buff from the BPF programs.

Instead of requiring BPF flow dissector programs to look into skb,
pass all input data in the flow_keys.

Subject: net/sched: act_sample: fix divide by zero in the traffic path

the control path of 'sample' action does not validate the value of 'rate'
provided by the user, but then it uses it as divisor in the traffic path.
Validate it in tcf_sample_init(), and return -EINVAL with a proper extack
message in case that value is zero, to fix a splat with the script below:

 # tc f a dev test0 egress matchall action sample rate 0 group 1 index 2
 # tc -s a s action sample
 total acts 1

         action order 0: sample rate 1/0 group 1 pipe
          index 2 ref 1 bind 1 installed 19 sec used 19 sec
         Action statistics:
         Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
         backlog 0b 0p requeues 0

Subject: selftests: fib_tests: Fix 'Command line is not complete' errors

A couple of tests are verifying a route has been removed. The helper
expects the prefix as the first part of the expected output. When
checking that a route has been deleted the prefix is empty leading
to an invalid ip command:

  $ ip ro ls match
  Command line is not complete. Try option "help"

Fix by moving the comparison of expected output and output to a new
function that is used by both check_route and check_route6. Use the
new helper for the 2 checks on route removal.

Also, remove the reset of 'set -x' in route_setup which overrides the
user managed setting.

Subject: selftests: netfilter: check icmp pkttoobig errors are set as related

When an icmp error such as pkttoobig is received, conntrack checks
if the "inner" header (header of packet that did not fit link mtu)
is matches an existing connection, and, if so, sets that packet as
being related to the conntrack entry it found.

It was recently reported that this "related" setting also works
if the inner header is from another, different connection (i.e.,
artificial/forged icmp error).

Add a test, followup patch will add additional "inner dst matches
outer dst in reverse direction" check before setting related state.

Subject: netfilter: nat: fix icmp id randomization

Sven Auhagen reported that a 2nd ping request will fail if 'fully-random'
mode is used.

Reason is that if no proto information is given, min/max are both 0,
so we set the icmp id to 0 instead of chosing a random value between
0 and 65535.

Update test case as well to catch this, without fix this yields:
[..]
ERROR: cannot ping ns1 from ns2 with ip masquerade fully-random (attempt 2)
ERROR: cannot ping ns1 from ns2 with ipv6 masquerade fully-random (attempt 2)

... becaus 2nd ping clashes with existing 'id 0' icmp conntrack and gets
dropped.

Subject: selftests: kvm/evmcs_test: complete I/O before migrating guest state

Starting state migration after an IO exit without first completing IO
may result in test failures.  We already have two tests that need this
(this patch in fact fixes evmcs_test, similar to what was fixed for
state_test in commit 0f73bbc851ed, "KVM: selftests: complete IO before
migrating guest state", 2019-03-13) and a third is coming.  So, move the
code to vcpu_save_state, and while at it do not access register state
until after I/O is complete.

Subject: selftests: kvm: add a selftest for SMM

Add a simple test for SMM, based on VMX.  The test implements its own
sync between the guest and the host as using our ucall library seems to
be too cumbersome: SMI handler is happening in real-address mode.

This patch also fixes KVM_SET_NESTED_STATE to happen after
KVM_SET_VCPU_EVENTS, in fact it places it last.  This is because
KVM needs to know whether the processor is in SMM or not.

Subject: proc: fix map_files test on F29

F29 bans mapping first 64KB even for root making test fail.  Iterate
from address 0 until mmap() works.

Gentoo (root):

	openat(AT_FDCWD, "/dev/zero", O_RDONLY) = 3
	mmap(NULL, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = 0

Gentoo (non-root):

	openat(AT_FDCWD, "/dev/zero", O_RDONLY) = 3
	mmap(NULL, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EPERM (Operation not permitted)
	mmap(0x1000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = 0x1000

F29 (root):

	openat(AT_FDCWD, "/dev/zero", O_RDONLY) = 3
	mmap(NULL, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x1000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)

	mmap(0x3000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x4000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x5000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x6000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x7000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x8000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)

	mmap(0xc000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0xd000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0xe000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0xf000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = -1 EACCES (Permission denied)
	mmap(0x10000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED, 3, 0) = 0x10000

Now all proc tests succeed on F29 if run as root, at last!

This is because the test script itself has been successfully executed.

Subject: selftests/bpf: test cases for pkt/null checks in subprogs

The first test case, for pointer null checks, is equivalent to the
following pseudo-code.  It checks that the verifier does not complain on
line 6 and recognizes that ptr isn't null.

1: ptr = bpf_map_lookup_elem(map, &key);
2: ret = subprog(ptr) {
3:   return ptr != NULL;
4: }
5: if (ret)
6:   value = *ptr;

The second test case, for packet bound checks, is equivalent to the
following pseudo-code.  It checks that the verifier does not complain on
line 7 and recognizes that the packet is at least 1 byte long.

1: pkt_end = ctx.pkt_end;
2: ptr = ctx.pkt + 8;
3: ret = subprog(ptr, pkt_end) {
4:   return ptr <= pkt_end;
5: }
6: if (ret)
7:   value = *(u8 *)ctx.pkt;

Subject: KVM: fix KVM_CLEAR_DIRTY_LOG for memory slots of unaligned size

If a memory slot's size is not a multiple of 64 pages (256K), then
the KVM_CLEAR_DIRTY_LOG API is unusable: clearing the final 64 pages
either requires the requested page range to go beyond memslot->npages,
or requires log->num_pages to be unaligned, and kvm_clear_dirty_log_protect
requires log->num_pages to be both in range and aligned.

To allow this case, allow log->num_pages not to be a multiple of 64 if
it ends exactly on the last page of the slot.
