This fixes a few issues reported by ShellCheck:
- SC2068: Double quote array expansions to avoid re-splitting elements.
- SC2206: Quote to prevent word splitting/globbing, or split robustly
with mapfile or read -a.
- SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
- SC2155: Declare and assign separately to avoid masking return values.
- SC2162: read without -r will mangle backslashes.
- SC2219: Instead of 'let expr', prefer (( expr )) .
- SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly
with $?.
- SC2236: Use -n instead of ! -z.
- SC2004: $/${} is unnecessary on arithmetic variables.
- SC2012: Use find instead of ls to better handle non-alphanumeric
filenames.
- SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..'
instead.
SC2086 (Double quotes to prevent globbing and word splitting) is ignored
because it is controlled for the moment and there are too many to
change.
While at it, also fixed the alignment in one comment.

As explained on ShellCheck's wiki [1], it is recommended to avoid
backquotes `...` in favour of parenthesis $(...):
> Backtick command substitution `...` is legacy syntax with several
> issues.
>
> - It has a series of undefined behaviors related to quoting in POSIX.
> - It imposes a custom escaping mode with surprising results.
> - It's exceptionally hard to nest.
>
> $(...) command substitution has none of these problems, and is
> therefore strongly encouraged.

Some vars are redefined in different places. Best to avoid this
classical Bash pitfall where variables are accidentally overridden by
other functions because the proper scope has not been defined.
Most issues are with loops: typically 'i' is used in for-loops but if it
is not global, calling a function from a for-loop also doing a for-loop
with the same non local 'i' variable causes troubles because the first
'i' will be assigned to another value. To prevent such issues, the
iterator variable is now declared as local just before the loop. If it
is always done like this, issues are avoided.
To distinct between local and non local variables, all non local ones
are defined at the beginning of the script. The others are now defined
with the "local" keyword.

With ~100 tests, it helps to have this summary at the end not to scroll
to find which one has failed.
It is especially interseting when looking at the output produced by the
CI where the kernel logs from the serial are mixed together.

Running a specific test by giving the ID is often what we want: the CI
reports an issue with the Nth test, it is reproducible with:
./mptcp_join.sh N
But this might not work when there is a need to find which commit has
introduced a regression making a test unstable: failing from time to
time. Indeed, a specific test is not attached to one ID: the ID is in
fact a counter. It means the same test can have a different ID if other
tests have been added/removed before this unstable one.
Remembering the current test can also help listing failed tests at the
end.

Often, it is needed to run one specific test.
There are options to run subgroups of tests but when only one fails, no
need to run all the subgroup. So far, the solution was to edit the
script to comment the tests that are not needed but that's not ideal.
Now, it is possible to run one specific test by giving the ID of the
tests that are going to be validated, e.g.
./mptcp_join.sh 36 37
This is cleaner and saves time.
Technically, the reset* functions now return 0 if the test can be
executed. This naturally creates sections per test in the code which is
also helpful to understand what a test is exactly doing.

When adding a new tests group, it has to be defined in multiple places:
- in the all_tests() function
- in the 'usage()' function
- in the getopts: short option + what to do when the option is used
Because it is easy to forget one of them, it is useful to have to define
them only once.
Note: only using an associative array would simplify the code but the
entries are stored in a hashtable and iterating over the different items
doesn't give the same order as the one used in the declaration of this
array. Because we want to run these tests in the same order as before, a
"simple" array is used first.

In some edge scenarios, an MPTCP subflows can use a local address
mapped by a "implicit" endpoint created by the in-kernel path manager.
Such endpoints presence can be confusing, as it's creation is hard
to track and will prevent the later endpoint creation from the user-space
using the same address.
Define a new endpoint flag to mark implicit endpoints and allow the
user-space to replace implicit them with user-provided data at endpoint
creation time.

The in-kernel MPTCP path manager, when processing the MPTCP_PM_CMD_FLUSH_ADDR
command, generates RM_ADDR events for each known local address. While that
is allowed by the RFC, it makes unpredictable the exact number of RM_ADDR
generated when both ends flush the PM addresses.
This change restricts the RM_ADDR generation to previously explicitly
announced addresses, and adjust the expected results in a bunch of related
self-tests.

The "selftests: mptcp: improve 'fair usage on close' stability" commit
changed that self test to check the TcpAttemptFails MIB instead of
looking for TW sockets. The associated bash function wasn't renamed in
that commit because of the merge conflicts it would cause, so this
commit updates the function name as Paolo originally intended.

Without this patch, no tests would be ran when launching:
mptcp_join.sh -cCi
In any order or a combination with 2 of these letters.
The recommended way with getopt is first parse all options and then act.
This allows to do some actions in priority, e.g. display the help menu
and stop.
But also some global variables changing the behaviour of this selftests
-- like the ones behind -cCi options -- can be set before running the
different tests. By doing that, we can also avoid long and unreadable
regex.

This patch added five more arguments for chk_join_nr(). The default
values of them are all zero.
The first two, csum_ns1 and csum_ns1, are passed to chk_csum_nr(), to
check the mib counters of the checksum errors in ns1 and ns2. A '+'
can be added into this two arguments to represent that multiple
checksum errors are allowed when doing this check. For example,
chk_csum_nr "" +2 +2
indicates that two or more checksum errors are allowed in both ns1 and
ns2.
The remaining two, fail_nr and rst_nr, are passed to chk_fail_nr() and
chk_rst_nr() respectively, to check the sending and receiving mib
counters of MP_FAIL and MP_RST.
Also did some cleanups in chk_fail_nr(), renamed two local variables
and updated the output message.

This patch added the self test for MP_FASTCLOSE. Reused the argument
addr_nr_ns2 of do_transfer() to pass the extra arguments '-I 2' to
mptcp_connect commands. Then mptcp_connect disconnected the
connections to trigger the MP_FASTCLOSE sending and receiving. Used
chk_fclose_nr to check the MP_FASTCLOSE mibs and used chk_rst_nr to
check the MP_RST mibs. This test used the test_linkfail value to make
1024KB test files.
The output looks like this:
Created /tmp/tmp.XB8sfv1hJ0 (size 1024 KB) containing data sent by client
Created /tmp/tmp.RtTDbzqrXI (size 1024 KB) containing data sent by server

We've added 32 non-merge commits during the last 14 day(s) which contain
a total of 59 files changed, 1038 insertions(+), 473 deletions(-).
The main changes are:
1) Optimize BPF stackmap's build_id retrieval by caching last valid build_id,
as consecutive stack frames are likely to be in the same VMA and therefore
have the same build id, from Hao Luo.
2) Several improvements to arm64 BPF JIT, that is, support for JITing
the atomic[64]_fetch_add, atomic[64]_[fetch_]{and,or,xor} and lastly
atomic[64]_{xchg|cmpxchg}. Also fix the BTF line info dump for JITed
programs, from Hou Tao.
3) Optimize generic BPF map batch deletion by only enforcing synchronize_rcu()
barrier once upon return to user space, from Eric Dumazet.
4) For kernel build parse DWARF and generate BTF through pahole with enabled
multithreading, from Kui-Feng Lee.
5) BPF verifier usability improvements by making log info more concise and
replacing inv with scalar type name, from Mykola Lysenko.
6) Two follow-up fixes for BPF prog JIT pack allocator, from Song Liu.
7) Add a new Kconfig to allow for loading kernel modules with non-matching
BTF type info; their BTF info is then removed on load, from Connor O'Brien.
8) Remove reallocarray() usage from bpftool and switch to libbpf_reallocarray()
in order to fix compilation errors for older glibc, from Mauricio Vásquez.
9) Fix libbpf to error on conflicting name in BTF when type declaration
appears before the definition, from Xu Kuohai.
10) Fix issue in BPF preload for in-kernel light skeleton where loaded BPF
program fds prevent init process from setting up fd 0-2, from Yucong Sun.
11) Fix libbpf reuse of pinned perf RB map when max_entries is auto-determined
by libbpf, from Stijn Tintel.
12) Several cleanups for libbpf and a fix to enforce perf RB map #pages to be
non-zero, from Yuntao Wang.

The test runs several test cases and is supposed to return an error in
case at least one of them failed.
Currently, the check of the return value of each test case is in the
wrong place, which can result in the wrong return value. For example:
# TESTS='tc_police' ./resource_scale.sh
TEST: 'tc_police' [default] 968 [FAIL]
tc police offload count failed
Error: mlxsw_spectrum: Failed to allocate policer index.
We have an error talking to the kernel
Command failed /tmp/tmp.i7Oc5HwmXY:969
TEST: 'tc_police' [default] overflow 969 [ OK ]
...
TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ]
$ echo $?
0
Fix this by moving the check to be done after each test case.

resulting in incorrect results.
Fix that by using JSON output instead.

Netfilter fixes for net
1) Use kfree_rcu(ptr, rcu) variant, using kfree_rcu(ptr) was not
intentional. From Eric Dumazet.
2) Use-after-free in netfilter hook core, from Eric Dumazet.
3) Missing rcu read lock side for netfilter egress hook,
from Florian Westphal.
4) nf_queue assume state->sk is full socket while it might not be.
Invoke sock_gen_put(), from Florian Westphal.
5) Add selftest to exercise the reported KASAN splat in 4)
6) Fix possible use-after-free in nf_queue in case sk_refcnt is 0.
Also from Florian.
7) Use input interface index only for hardware offload, not for
the software plane. This breaks tc ct action. Patch from Paul Blakey.

Running the memfd script ./run_hugetlbfs_test.sh will often end in error
as follows:
memfd-hugetlb: CREATE

memfd-hugetlb: SEAL-WRITE
memfd-hugetlb: SEAL-FUTURE-WRITE
memfd-hugetlb: SEAL-SHRINK
fallocate(ALLOC) failed: No space left on device
./run_hugetlbfs_test.sh: line 60: 166855 Aborted (core dumped) ./memfd_test hugetlbfs
opening: ./mnt/memfd
fuse: DONE
If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will
allocate 'just enough' pages to run the test. In the SEAL-FUTURE-WRITE
test the mfd_fail_write routine maps the file, but does not unmap. As a
result, two hugetlb pages remain reserved for the mapping. When the
fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb
pages, it is short by the two reserved pages.
Fix by making sure to unmap in mfd_fail_write.

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 5.17, take #4
- Correctly synchronise PMR and co on PSCI CPU_SUSPEND
- Skip tests that depend on GICv3 when the HW isn't available
|
|
The arch_timer and vgic_irq kselftests assume that they can create a
vgic-v3, using the library function vgic_v3_setup() which aborts with a
test failure if it is not possible to do so. Since vgic-v3 can only be
instantiated on systems where the host has GICv3 this leads to false
positives on older systems where that is not the case.
Fix this by changing vgic_v3_setup() to return an error if the vgic can't
be instantiated and have the callers skip if this happens. We could also
exit flagging a skip in vgic_v3_setup() but this would prevent future test
cases conditionally deciding which GIC to use or generally doing more
complex output.

Add option to shift the clock by a specified number of nanoseconds.
The new argument -n will specify the number of nanoseconds to add to the

This test tries to pass a PTR_TO_BTF_ID_OR_NULL to the release function,
which would trigger a out of bounds access without the fix in commit
45ce4b4f9009 ("bpf: Fix crash due to out of bounds access into reg2btf_ids.")
but after the fix, it should only index using base_type(reg->type),
which should be less than __BPF_REG_TYPE_MAX, and also not permit any
type flags to be set for the reg->type.
