4a621e2910 A couple of fixes for tracing:
- Prevent a NULL pointer dereference in the error path of RTLA tool
 
 - Fix an infinite loop bug when reading from the ring buffer when closed.
   If there's a thread trying to read the ring buffer and it gets closed
   by another thread, the one reading will go into an infinite loop
   when the buffer is empty instead of exiting back to user space.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Ignores ifindex for types other than mcast/linklocal in ipv6 frag
   reasm, from Tom Hughes.

2) Initialize extack for begin/end netlink message marker in batch,
   from Donald Hunter.

3) Initialize extack for flowtable offload support, also from Donald.

4) Dropped packets with cloned unconfirmed conntracks in nfqueue,
   later it should be possible to explore lookup after reinject but
   Florian prefers this approach at this stage. From Florian Westphal.

5) Add selftest for cloned unconfirmed conntracks in nfqueue for
   previous update.

6) Audit after filling netlink header successfully in object dump,
   from Phil Sutter.

7-8) Fix concurrent dump and reset which could result in underflow
     counter / quota objects.

7965a7f32a selftests: net: lib: kill PIDs before del netns
When deleting netns, it is possible to still have some tasks running,
e.g. background tasks like tcpdump running in the background, not
stopped because the test has been interrupted.

Before deleting the netns, it is then safer to kill all attached PIDs,
if any. That should reduce some noises after the end of some tests, and
help with the debugging of some issues. That's why this modification is
seen as a "fix".

Add a test to verify that userspace can't change a vCPU's x2APIC ID by
abusing KVM_SET_LAPIC.  KVM models the x2APIC ID (and x2APIC LDR) as
readonly, and silently ignores userspace attempts to change the x2APIC ID
for backwards compatibility.

662c3e2db0 selftests/bpf: Add a test to verify previous stacksafe() fix
A selftest is added such that without the previous patch,
a crash can happen. With the previous patch, the test can
run successfully. The new test is written in a way which
mimics original crash case:
  main_prog
    static_prog_1
      static_prog_2
where static_prog_1 has different paths to static_prog_2
and some path has stack allocated and some other path
does not. A stacksafe() checking in static_prog_2()
triggered the crash.

1d2c46c1bc selftests/net: Add coverage for UDP GSO with IPv6 extension headers
After enabling UDP GSO for devices not offering checksum offload, we have
hit a regression where a bad offload warning can be triggered when sending
a datagram with IPv6 extension headers.

Extend the UDP GSO IPv6 tests to cover this scenario.

90574d2a67 rtla/osnoise: Prevent NULL dereference in error handling
If the "tool->data" allocation fails then there is no need to call
osnoise_free_top() and, in fact, doing so will lead to a NULL dereference.

30b651c8bc selftests: mm: add s390 to ARCH check
commit 0518dbe97f ("selftests/mm: fix cross compilation with LLVM")
changed the env variable for the architecture from MACHINE to ARCH.

This is preventing 3 required TEST_GEN_FILES from being included when
cross compiling s390x and errors when trying to run the test suite.  This
is due to the ARCH variable already being set and the arch folder name
being s390.

Add "s390" to the filtered list to cover this case and have the 3 files
included in the build.

9a2fa14720 fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first
count/BITS_PER_LONG bits from old->full_fds_bits[] and fill
the rest with zeroes.  What it does is copying enough words
(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.
That works fine, *if* all bits past the cutoff point are
clear.  Otherwise we are risking garbage from the last word
we'd copied.

For most of the callers that is true - expand_fdtable() has
count equal to old->max_fds, so there's no open descriptors
past count, let alone fully occupied words in ->open_fds[],
which is what bits in ->full_fds_bits[] correspond to.

The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),
which is the smallest multiple of BITS_PER_LONG that covers all
opened descriptors below max_fds.  In the common case (copying on
fork()) max_fds is ~0U, so all opened descriptors will be below
it and we are fine, by the same reasons why the call in expand_fdtable()
is safe.

Unfortunately, there is a case where max_fds is less than that
and where we might, indeed, end up with junk in ->full_fds_bits[] -
close_range(from, to, CLOSE_RANGE_UNSHARE) with
	* descriptor table being currently shared
	* 'to' being above the current capacity of descriptor table
	* 'from' being just under some chunk of opened descriptors.
In that case we end up with observably wrong behaviour - e.g. spawn
a child with CLONE_FILES, get all descriptors in range 0..127 open,
then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending
up with descriptor #128, despite #64 being observably not open.

The minimally invasive fix would be to deal with that in dup_fd().
If this proves to add measurable overhead, we can go that way, but
let's try to fix copy_fd_bitmaps() first.

* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
* make copy_fd_bitmaps() take the bitmap size in words, rather than
bits; it's 'count' argument is always a multiple of BITS_PER_LONG,
so we are not losing any information, and that way we can use the
same helper for all three bitmaps - compiler will see that count
is a multiple of BITS_PER_LONG for the large ones, so it'll generate
plain memcpy()+memset().

This kselftest fixes update consists of a single fix to the conditional
 in ksft.py script which incorrectly flags a test suite failed when there
 are skipped tests in the mix. The logic is fixed to take skipped tests
 into account and report the test as passed.

54233a4254 uretprobe: change syscall number, again
Despite multiple attempts to get the syscall number assignment right
for the newly added uretprobe syscall, we ended up with a bit of a mess:

 - The number is defined as 467 based on the assumption that the
   xattrat family of syscalls would use 463 through 466, but those
   did not make it into 6.11.

 - The include/uapi/asm-generic/unistd.h file still lists the number
   463, but the new scripts/syscall.tbl that was supposed to have the
   same data lists 467 instead as the number for arc, arm64, csky,
   hexagon, loongarch, nios2, openrisc and riscv. None of these
   architectures actually provide a uretprobe syscall.

 - All the other architectures (powerpc, arm, mips, ...) don't list
   this syscall at all.

There are two ways to make it consistent again: either list it with
the same syscall number on all architectures, or only list it on x86
but not in scripts/syscall.tbl and asm-generic/unistd.h.

Based on the most recent discussion, it seems like we won't need it
anywhere else, so just remove the inconsistent assignment and instead
move the x86 number to the next available one in the architecture
specific range, which is 335.

4d2868b5d1 selftests: mptcp: join: test both signal & subflow
It should be quite uncommon to set both the subflow and the signal
flags: the initiator of the connection is typically the one creating new
subflows, not the other peer, then no need to announce additional local
addresses, and use it to create subflows.

But some people might be confused about the flags, and set both "just to
be sure at least the right one is set". To verify the previous fix, and
avoid future regressions, this specific case is now validated: the
client announces a new address, and initiates a new subflow from the
same address.

While working on this, another bug has been noticed, where the client
reset the new subflow because an ADD_ADDR echo got received as the 3rd
ACK: this new test also explicitly checks that no RST have been sent by
the client and server.

The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

perf arch events: Fix duplicate RISC-V SBI firmware event name
Currently, the RISC-V firmware JSON file has duplicate event name
"FW_SFENCE_VMA_RECEIVED". According to the RISC-V SBI PMU extension[1],
the event name should be "FW_SFENCE_VMA_ASID_SENT".

Before this patch:
$ perf list

       [Load access trap event. Unit: cpu]
  fw_access_store
       [Store access trap event. Unit: cpu]

  fw_sfence_vma_received
       [Sent SFENCE.VMA with ASID request to other HART event. Unit: cpu]

After this patch:
$ perf list

firmware:
  fw_access_load
       [Load access trap event. Unit: cpu]
  fw_access_store
       [Store access trap event. Unit: cpu]

f833470c27 selftests: mptcp: join: check backup support in signal endp
Before the previous commit, 'signal' endpoints with the 'backup' flag
were ignored when sending the MP_JOIN.

The MPTCP Join selftest has then been modified to validate this case:
the "single address, backup" test, is now validating the MP_JOIN with a
backup flag as it is what we expect it to do with such name. The
previous version has been kept, but renamed to "single address, switch
to backup" to avoid confusions.

The "single address with port, backup" test is also now validating the
MPJ with a backup flag, which makes more sense than checking the switch
to backup with an MP_PRIO.

The "mpc backup both sides" test is now validating that the backup flag
is also set in MP_JOIN from and to the addresses used in the initial
subflow, using the special ID 0.

The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

935ff5bb8a selftests: mptcp: join: validate backup in MPJ
A peer can notify the other one that a subflow has to be treated as
"backup" by two different ways: either by sending a dedicated MP_PRIO
notification, or by setting the backup flag in the MP_JOIN handshake.

The selftests were previously monitoring the former, but not the latter.
This is what is now done here by looking at these new MIB counters when
validating the 'backup' cases:

  MPTcpExtMPJoinSynBackupRx
  MPTcpExtMPJoinSynAckBackupRx

The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it will help to validate a new fix for an issue introduced by this
commit ID.

41c24102af selftests/bpf: Filter out _GNU_SOURCE when compiling test_cpp
Jakub reports build failures when merging linux/master with net tree:

CXX      test_cpp
In file included from <built-in>:454:
<command line>:2:9: error: '_GNU_SOURCE' macro redefined [-Werror,-Wmacro-redefined]
    2 | #define _GNU_SOURCE
      |         ^
<built-in>:445:9: note: previous definition is here
  445 | #define _GNU_SOURCE 1

The culprit is commit cc937dad85 ("selftests: centralize -D_GNU_SOURCE= to
CFLAGS in lib.mk") which unconditionally added -D_GNU_SOUCE to CLFAGS.
Apparently clang++ also unconditionally adds it for the C++ targets [0]
which causes a conflict. Add small change in the selftests makefile
to filter it out for test_cpp.

Not sure which tree it should go via, targeting bpf for now, but net
might be better?
