Linus Torvalds f291209eca Including fixes from Bluetooth, netfilter, BPF and WiFi.
I didn't collect precise data but feels like we've got a lot
 of 6.5 fixes here. WiFi fixes are most user-awaited.
 
 Current release - regressions:
 
  - Bluetooth: fix hci_link_tx_to RCU lock usage
 
 Current release - new code bugs:
 
  - bpf: mprog: fix maximum program check on mprog attachment
 
  - eth: ti: icssg-prueth: fix signedness bug in prueth_init_tx_chns()

====================
netfilter patches for net

First patch resolves a regression with vlan header matching, this was
broken since 6.5 release.  From myself.

Second patch fixes an ancient problem with sctp connection tracking in
case INIT_ACK packets are delayed.  This comes with a selftest, both
patches from Xin Long.

Patch 4 extends the existing nftables audit selftest, from
Phil Sutter.

Patch 5, also from Phil, avoids a situation where nftables
would emit an audit record twice. This was broken since 5.13 days.

Patch 6, from myself, avoids spurious insertion failure if we encounter an
overlapping but expired range during element insertion with the
'nft_set_rbtree' backend. This problem exists since 6.2.

Florian Westphal says:

====================
netfilter updates for net-next

First patch, from myself, is a bug fix. The issue (connect timeout) is
ancient, so I think its safe to give this more soak time given the esoteric
conditions needed to trigger this.
Also updates the existing selftest to cover this.

Add netlink extacks when an update references a non-existent
table/chain/set.  This allows userspace to provide much better
errors to the user, from Pablo Neira Ayuso.

Last patch adds more policy checks to nf_tables as a better
alternative to the existing runtime checks, from Phil Sutter.

Phil Sutter 0d880dc6f0 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.

Xin Long cf791b22be 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.

Juntong Deng bbe246f875 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

Pedro Tammela ac9b829309 selftests/tc-testing: implement tdc parallel test run
Use a Python process pool to run the tests in parallel.
Not all tests can run in parallel, for instance tests that are not
namespaced and tests that use netdevsim, as they can conflict with one
another.

The code logic will split the tests into serial and parallel.
For the parallel tests, we build batches of 32 tests and queue each
batch on the process pool. For the serial tests, they are queued as a
whole into the process pool, which in turn executes them concurrently
with the parallel tests.

Even though the tests serialize on rtnl_lock in the kernel, this feature
showed results with a ~3x speedup on the wall time for the entire test suite
running in a VM:
   Before - 4m32.502s
   After - 1m19.202s

Examples:
   In order to run tdc using 4 processes:
      ./tdc.py -J4 <...>
   In order to run tdc using 1 process:
      ./tdc.py -J1 <...> || ./tdc.py <...>

Note that the kernel configuration will affect the speed of the tests,
especially if such configuration slows down process creation and/or
fork().

Pedro Tammela 98cfbe4234 selftests/tc-testing: localize test resources
As of today, the current tdc architecture creates one netns and uses it
to run all tests. This assumption was embedded into the nsPlugin which
carried over as how the tests were written.

The tdc tests are by definition self contained and can,
theoretically, run in parallel. Even though in the kernel they will
serialize over the rtnl lock, we should expect a significant speedup of the
total wall time for the entire test suite, which is hitting close to
1100 tests at this point.

A first step to achieve this goal is to remove sharing of global resources like
veth/dummy interfaces and the netns. In this patch we 'localize' these
resources on a per test basis. Each test gets it's own netns, VETH/dummy interfaces.
The resources are spawned in the pre_suite phase, where tdc will prepare
all netns and interfaces for all tests. This is done in order to avoid
concurrency issues with netns / interfaces spawning and commands using
them. As tdc progresses, the resources are deleted after each test finishes
executing.

Tests that don't use the nsPlugin still run under the root namespace,
but are now required to manage any external resources like interfaces.
These cannot be parallelized as their definition doesn't allow it.
On the other hand, when using the nsPlugin, tests don't need to create
dummy/veth interfaces as these are handled already.

Michael Ellerman 58b33e78a3 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 d4e59a536f ("selftests: Use runner.sh
for emit targets"). Although prior to that commit a548de0fe8
("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

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

Ryan Roberts c652df8a4a selftests: link libasan statically for tests with -fsanitize=address
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 58e2847ad2 ("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

Modifications to kci_test_addrlft() and kci_test_ipsec_offload()

failure. This allows end_test to really easily implement pause on fail

Uses a run_cmd helper function similar to other selftests to add
verbose functionality i.e. print executed commands and their outputs

Many commands silence or redirect output. This can be removed since
the verbose helper function captures output anyway and only outputs it
if VERBOSE is true. Similarly, the helper command for pipes to grep
searches stderr and stdout. This makes output redirection unnecessary
in those cases.
