Subject: selftests/user_events: Fix to unmount tracefs when test created mount

Fix to unmount tracefs if the self-test mounted it to allow testing.
If tracefs was already mounted, this does nothing.

Subject: selftests/bpf: Check bpf_cubic_acked() is called via struct_ops

Test bpf_tcp_ca (in test_progs) checks multiple tcp_congestion_ops.
However, there isn't a test that verifies functions in the
tcp_congestion_ops is actually called. Add a check to verify that
bpf_cubic_acked is actually called during the test.

Subject: selftests: link libasan statically for tests with -fsanitize=address
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When dynamically linking, Address Sanitizer requires its library to be the
first one to be loaded; this is apparently to ensure that every call to
malloc is intercepted.  If using LD_PRELOAD, those listed libraries will
be loaded before the libraries listed in the program's ELF and will
therefore violate this requirement, leading to the below failure and
output from ASan.

commit 58e2847ad2e6 ("selftests: line buffer test program's stdout")
modified the kselftest runner to force line buffering by forcing the test
programs to run through `stdbuf`.  It turns out that stdbuf implements
line buffering by injecting a library via LD_PRELOAD.  Therefore selftests
that use ASan started failing.

Fix this by statically linking libasan in the affected test programs,
using the `-static-libasan` option.  Note this is already the default for
Clang, but not got GCC.

Test output sample for failing case:

  TAP version 13
  1..3
  # timeout set to 300
  # selftests: openat2: openat2_test
  # ==4052==ASan runtime does not come first in initial library list;
  you should either link runtime to your application or manually preload
  it with LD_PRELOAD.
  not ok 1 selftests: openat2: openat2_test # exit=1
  # timeout set to 300
  # selftests: openat2: resolve_test
  # ==4070==ASan runtime does not come first in initial library list;
  you should either link runtime to your application or manually preload
  it with LD_PRELOAD.
  not ok 2 selftests: openat2: resolve_test # exit=1

Subject: KVM: selftests: Assert that vasprintf() is successful
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Assert that vasprintf() succeeds as the "returned" string is undefined
on failure.  Checking the result also eliminates the only warning with
default options in KVM selftests, i.e. is the only thing getting in the
way of compile with -Werror.

  lib/test_util.c: In function ‘strdup_printf’:
  lib/test_util.c:390:9: error: ignoring return value of ‘vasprintf’
  declared with attribute ‘warn_unused_result’ [-Werror=unused-result]
  390 |         vasprintf(&str, fmt, ap);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~

Don't bother capturing the return value, allegedly vasprintf() can only
fail due to a memory allocation failure.

Subject: KVM: riscv: selftests: Fix ISA_EXT register handling in get-reg-list

Same set of ISA_EXT registers are not present on all host because
ISA_EXT registers are visible to the KVM user space based on the
ISA extensions available on the host. Also, disabling an ISA
extension using corresponding ISA_EXT register does not affect
the visibility of the ISA_EXT register itself.

Based on the above, we should filter-out all ISA_EXT registers.

Subject: KVM: riscv: selftests: Selectively filter-out AIA registers

Currently the AIA ONE_REG registers are reported by get-reg-list
as new registers for various vcpu_reg_list configs whenever Ssaia
is available on the host because Ssaia extension can only be
disabled by Smstateen extension which is not always available.

To tackle this, we should filter-out AIA ONE_REG registers only
when Ssaia can't be disabled for a VCPU.

Subject: selftests/powerpc: Fix emit_tests to work with run_kselftest.sh

In order to use run_kselftest.sh the list of tests must be emitted to
populate kselftest-list.txt.

The powerpc Makefile is written to use EMIT_TESTS. But support for
EMIT_TESTS was dropped in commit d4e59a536f50 ("selftests: Use runner.sh
for emit targets"). Although prior to that commit a548de0fe8e1
("selftests: lib.mk: add test execute bit check to EMIT_TESTS") had
already broken run_kselftest.sh for powerpc due to the executable check
using the wrong path.

It can be fixed by replacing the EMIT_TESTS definitions with actual
emit_tests rules in the powerpc Makefiles. This makes run_kselftest.sh
able to run powerpc tests:

  $ cd linux
  $ export ARCH=powerpc
  $ export CROSS_COMPILE=powerpc64le-linux-gnu-
  $ make headers
  $ make -j -C tools/testing/selftests install
  $ grep -c "^powerpc" tools/testing/selftests/kselftest_install/kselftest-list.txt

Subject: bpf, sockmap: Add tests for MSG_F_PEEK

Test that we can read with MSG_F_PEEK and then still get correct number
of available bytes through FIONREAD. The recv() (without PEEK) then
returns the bytes as expected. The recv() always worked though because
it was just the available byte reporting that was broke before latest
fixes.

Subject: selftests/mm: fix awk usage in charge_reserved_hugetlb.sh and
 hugetlb_reparenting_test.sh that may cause error

According to the awk manual, the -e option does not need to be specified
in front of 'program' (unless you need to mix program-file).

The redundant -e option can cause error when users use awk tools other
than gawk (for example, mawk does not support the -e option).

Error Example:
awk: not an option: -e

Subject: selftests: netfilter: test for sctp collision processing in
 nf_conntrack

This patch adds a test case to reproduce the SCTP DATA chunk retransmission
timeout issue caused by the improper SCTP collision processing in netfilter
nf_conntrack_proto_sctp.

In this test, client sends a INIT chunk, but the INIT_ACK replied from
server is delayed until the server sends a INIT chunk to start a new
connection from its side. After the connection is complete from server
side, the delayed INIT_ACK arrives in nf_conntrack_proto_sctp.

The delayed INIT_ACK should be dropped in nf_conntrack_proto_sctp instead
of updating the vtag with the out-of-date init_tag, otherwise, the vtag
in DATA chunks later sent by client don't match the vtag in the conntrack
entry and the DATA chunks get dropped.

Subject: selftests: netfilter: Extend nft_audit.sh

Add tests for sets and elements and deletion of all kinds. Also
reorder rule reset tests: By moving the bulk rule add command up, the
two 'reset rules' tests become identical.

While at it, fix for a failing bulk rule add test's error status getting
lost due to its use in a pipe. Avoid this by using a temporary file.

Headings in diff output for failing tests contain no useful data, strip
them.

Subject: netfilter: nf_tables: Deduplicate nft_register_obj audit logs

When adding/updating an object, the transaction handler emits suitable
audit log entries already, the one in nft_obj_notify() is redundant. To
fix that (and retain the audit logging from objects' 'update' callback),
Introduce an "audit log free" variant for internal use.

Fixes: c520292f29b8 ("audit: log nftables configuration change events once per table")
