[ Upstream commit 2745aea6750ff0d2c48285d25bdb00e5b636ec8b ]
Some versions of iproute2 will output more than one line per entry, which
will cause the test to fail, like:
TEST: ipv6: list and flush cached exceptions [FAIL]
can't list cached exceptions
That happens, for example, with iproute2 4.15.0. When using the -oneline
option, this will work just fine:
TEST: ipv6: list and flush cached exceptions [ OK ]
This also works just fine with a more recent version of iproute2, like
5.4.0.
For some reason, two lines are printed for the IPv4 test no matter what
version of iproute2 is used. Use the same -oneline parameter there instead
of counting the lines twice.
Fixes: b964641e9925 ("selftests: pmtu: Make list_flush_ipv6_exception test more demanding")

[ Upstream commit 64801d19eba156170340c76f70ade743defcb8ce ]
The MAP_HUGETLB ("-H" option) of gup_benchmark fails:
$ sudo ./gup_benchmark -H
mmap: Invalid argument
This is because gup_benchmark.c is passing in a file descriptor to
mmap(), but the fd came from opening up the /dev/zero file. This
confuses the mmap syscall implementation, which thinks that, if the
caller did not specify MAP_ANONYMOUS, then the file must be a huge page
file. So it attempts to verify that the file really is a huge page
file, as you can see here:
ksys_mmap_pgoff()
{
if (!(flags & MAP_ANONYMOUS)) {
retval = -EINVAL;
if (unlikely(flags & MAP_HUGETLB && !is_file_hugepages(file)))
goto out_fput; /* THIS IS WHERE WE END UP */
else if (flags & MAP_HUGETLB) {
...proceed normally, /dev/zero is ok here...
...and of course is_file_hugepages() returns "false" for the /dev/zero
file.
The problem is that the user space program, gup_benchmark.c, really just
wants anonymous memory here. The simplest way to get that is to pass
MAP_ANONYMOUS whenever MAP_HUGETLB is specified, so that's what this
patch does.

[ Upstream commit 7541c87c9b7a7e07c84481f37f2c19063b44469b ]
"ctx:file_pos sysctl:read read ok narrow" works on s390 by accident: it
reads the wrong byte, which happens to have the expected value of 0.
Improve the test by seeking to the 4th byte and expecting 4 instead of
0.
This makes the latent problem apparent: the test attempts to read the
first byte of bpf_sysctl.file_pos, assuming this is the least-significant
byte, which is not the case on big-endian machines: a non-zero offset is
needed.
The point of the test is to verify narrow loads, so we cannot cheat our
way out by simply using BPF_W. The existence of the test means that such
loads have to be supported, most likely because llvm can generate them.
Fix the test by adding a big-endian variant, which uses an offset to
access the least-significant byte of bpf_sysctl.file_pos.
This reveals the final problem: verifier rejects accesses to bpf_sysctl
fields with offset > 0. Such accesses are already allowed for a wide
range of structs: __sk_buff, bpf_sock_addr and sk_msg_md to name a few.
Extend this support to bpf_sysctl by using bpf_ctx_range instead of
offsetof when matching field offsets.

commit 4d2fa82d98d2d296043a04eb517d7dbade5b13b8 upstream.
If the kernel accidentally uses DS or ES while the user values are
loaded, it will work fine for sane userspace. In the interest of
simulating maximally insane userspace, make sigreturn_32 zero out DS
and ES for the nasty parts so that inadvertent use of these segments
will crash.

commit 8caa016bfc129f2c925d52da43022171d1d1de91 upstream.
For reasons that I haven't quite fully diagnosed, running
mov_ss_trap_32 on a 32-bit kernel results in an infinite loop in
userspace. This appears to be because the hacky SYSENTER test
doesn't segfault as desired; instead it corrupts the program state
such that it infinite loops.
Fix it by explicitly clearing EBP before doing SYSENTER. This will
give a more reliable segfault.

commit 5b216ea1c40cf06eead15054c70e238c9bd4729e upstream.
Newer versions of GCC (>= 9) demand that the size of the string to be
copied must be explicitly smaller than the size of the destination.
Thus, the NULL char has to be taken into account on strncpy.
This will avoid the following compiling error:

[ Upstream commit 852c8cbf34d3b3130a05c38064dd98614f97d3a8 ]
Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per
test") solves the problem of kselftest_harness.h-using binary tests
possibly hanging forever. However, scripts and other binaries can still
hang forever. This adds a global timeout to each test script run.
To make this configurable (e.g. as needed in the "rtc" test case),
include a new per-test-directory "settings" file (similar to "config")
that can contain kselftest-specific settings. The first recognized field
is "timeout".
Additionally, this splits the reporting for timeouts into a specific
"TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

[ Upstream commit 6e06983dde969c15eb4fdab77f0eda8b18ea28e6 ]
Fix the following build error from "make TARGETS=kvm kselftest":
libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC
This error is seen when build is done from the main Makefile using
kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
are defined.
When build is invoked using:
"make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
aren't defined.
There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the
check to determine if --no-pie is necessary, which is the case when these
two aren't defined when "make -C tools/testing/selftests/kvm" runs.
Fix it by simplifying the no-pie-option logic. With this change, both
build variations work.

[ Upstream commit 4670d68b9254710fdeaf794cad54d8b2c9929e0a ]
Some recent changes in latest Clang started causing the following
warning when unrolling strobemeta test case main loop:
progs/strobemeta.h:416:2: warning: loop not unrolled: the optimizer was
unable to perform the requested transformation; the transformation might
be disabled or specified as part of an unsupported transformation
ordering [-Wpass-failed=transform-warning]
This patch simplifies loop's exit condition to depend only on constant
max iteration number (STROBE_MAX_MAP_ENTRIES), while moving early
termination logic inside the loop body. The changes are equivalent from
program logic standpoint, but fixes the warning. It also appears to
improve generated BPF code, as it fixes previously failing non-unrolled
strobemeta test cases.

enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.
With this change we only perform GSO if the # of segments is > 1 even

Some distributions (e.g., debian buster) do not install ping6. Re-use
the hook in pmtu.sh to detect this and fallback to ping.

[ Upstream commit ca7a03c4175366a92cee0ccc4fec0038c3266e26 ]
Commit 7d9e5f422150 removed references from certain dsts, but accounting
for this never translated down into the fib6 suppression code. This bug
was triggered by WireGuard users who use wg-quick(8), which uses the
"suppress-prefix" directive to ip-rule(8) for routing all of their
internet traffic without routing loops. The test case added here
causes the reference underflow by causing packets to evaluate a suppress
rule.

Add a new cgroup freezer selftest, which checks that if a cgroup is
frozen, their new child cgroups will properly inherit the frozen
state.
It creates a parent cgroup, freezes it, creates a child cgroup
and populates it with a dummy process. Then it checks that both
parent and child cgroup are frozen.

Cleanups of the tests in fib_nexthops.sh
1. Several tests noted unexpected route output, but the
discrepancy was not showing in the summary output and
overlooked in the verbose output. Add a WARNING message
to the summary output to make it clear a test is not showing
expected output.
2. Several check_* calls are missing extra data like scope and metric
causing mismatches when the nexthops or routes are correct - some of
them are a side effect of the evolving iproute2 command. Update the
data to the expected output.
3. Several check_routes are checking for the wrong nexthop data,
most likely a copy-paste-update error.
4. A couple of tests were re-using a nexthop id that already existed.
Fix those to use a new id.

test_btf_dump fails when run with O=, because it needs to access source
files and assumes they live in ./progs/, which is not the case in this
scenario.
Fix by instructing kselftest to copy btf_dump_test_case_*.c files to the
test directory. Since kselftest does not preserve directory structure,
adjust the test to look in ./progs/ and then in ./.

test_cgroup_storage fails on s390 with an assertion failure: packets are
dropped when they shouldn't. The problem is that BPF_DW packet count is
accessed as BPF_W with an offset of 0, which is not correct on
big-endian machines.
Since the point of this test is not to verify narrow loads/stores,
simply use BPF_DW when working with packet counts.

There is no reproducer, however, the warning can be reproduced
by adding rules with ever smaller prefixes.
The sanity check ("does the policy match the node") uses the prefix value
of the node before its updated to the smaller value.
To fix this, update the prefix earlier. The bug has no impact on tree
correctness, this is only to prevent a false warning.
