680acde13f selftests/bpf: add a new test to check the consumer update case
The subtest sends 33 packets at one time on purpose to see if xsk
exitting __xsk_generic_xmit() updates the global consumer of tx queue
when reaching the max loop (max_tx_budget, 32 by default). The number 33
can avoid xskq_cons_peek_desc() updates the consumer when it's about to
quit sending, to accurately check if the issue that the first patch
resolves remains. The new case will not check this issue in zero copy
mode.

e0f60ba041 selftest: af_unix: Add test for SO_INQ.
Let's add a simple test to check the basic functionality of SO_INQ.

The test does the following:

  1. Create socketpair in self->fd[]
  2. Enable SO_INQ
  3. Send data via self->fd[0]
  4. Receive data from self->fd[1]
  5. Compare the SCM_INQ cmsg with ioctl(SIOCINQ)

3dc6c76391 selftests: net: Add IPv6 support to netconsole basic tests
Add IPv6 support to the netconsole basic functionality tests by:

- Introducing separate IPv4 and IPv6 address variables (SRCIP4/SRCIP6,
  DSTIP4/DSTIP6) to replace the single SRCIP/DSTIP variables
- Adding select_ipv4_or_ipv6() function to choose protocol version
- Updating socat configuration to use UDP6-LISTEN for IPv6 tests
- Adding wait_for_port() wrapper to handle protocol-specific port waiting
- Expanding test matrix to run both basic and extended formats against
  both IPv4 and IPv6 protocols
- Improving cleanup to kill any remaining socat processes
- Adding sleep delays for better IPv6 packet handling reliability

The test now validates netconsole functionality across both IP versions,
improving test coverage for dual-stack network environments.

This test would avoid the regression fixed by commit f599020702 ("net:
netpoll: Initialize UDP checksum field before checksumming")

23ca32e4ea selftests: drv-net: Add test for devlink-rate traffic class bandwidth distribution
This test suite validates the functionality of the devlink-rate API for
traffic class (TC) bandwidth allocation. It ensures that bandwidth can
be distributed between different traffic classes as configured, and
verifies that explicit TC-to-queue mapping is required for the
allocation to be effective.

The first test (test_no_tc_mapping_bandwidth) is marked as expected
failure on mlx5, since the hardware automatically enforces traffic
class separation by dynamically moving queues to the correct TC
scheduler, even without explicit TC-to-queue mapping configuration.

Test output on mlx5:

81d572a551 selftest: net: extend msg_zerocopy test with forwarding
Zerocopy skbs are converted to regular copy skbs when data is queued
to a local socket. This happens in the existing test with a sender and
receiver communicating over a veth device.

Zerocopy skbs are sent without copying if egressing a device. Verify
that this behavior is maintained even in the common container setup
where data is forwarded over a veth to the physical device.

Update msg_zerocopy.sh to

1. Have a dummy network device to simulate a physical device.
2. Have forwarding enabled between veth and dummy.
3. Add a tx-only test that sends out dummy via the forwarding path.
4. Verify the exitcode of the sender, which signals zerocopy success.

As dummy drops all packets, this cannot be a TCP connection. Test
the new case with unconnected UDP only.

Update msg_zerocopy.c to
- Accept an argument whether send with zerocopy is expected.
- Return an exitcode whether behavior matched that expectation.

3a764d9338 vsock/test: Add test for null ptr deref when transport changes
Add a new test to ensure that when the transport changes a null pointer
dereference does not occur. The bug was reported upstream [1] and fixed
with commit 2cb7c756f6 ("vsock/virtio: discard packets if the
transport changes").

KASAN: null-ptr-deref in range [0x0000000000000060-0x0000000000000067]
CPU: 2 UID: 0 PID: 463 Comm: kworker/2:3 Not tainted
Workqueue: vsock-loopback vsock_loopback_work
RIP: 0010:vsock_stream_has_data+0x44/0x70
Call Trace:
 virtio_transport_do_close+0x68/0x1a0
 virtio_transport_recv_pkt+0x1045/0x2ae4
 vsock_loopback_work+0x27d/0x3f0
 process_one_work+0x846/0x1420
 worker_thread+0x5b3/0xf80
 kthread+0x35a/0x700
 ret_from_fork+0x2d/0x70
 ret_from_fork_asm+0x1a/0x30

Note that this test may not fail in a kernel without the fix, but it may
hang on the client side if it triggers a kernel oops.

This works by creating a socket, trying to connect to a server, and then
executing a second connect operation on the same socket but to a
different CID (0). This triggers a transport change. If the connect
operation is interrupted by a signal, this could cause a null-ptr-deref.

Since this bug is non-deterministic, we need to try several times. It
is reasonable to assume that the bug will show up within the timeout
period.

If there is a G2H transport loaded in the system, the bug is not
triggered and this test will always pass. This is because
`vsock_assign_transport`, when using CID 0, like in this case, sets
vsk->transport to `transport_g2h` that is not NULL if a G2H transport is
available.

b7863babce selftests: forwarding: lib: Split setup_wait()
setup_wait() takes an optional argument and then is called from the top
level of the test script. That confuses shellcheck, which thinks that maybe
the intention is to pass $1 of the script to the function, which is never
the case. To avoid having to annotate every single new test with a SC
disable, split the function in two: one that takes a mandatory argument,
and one that takes no argument at all.

Convert the two existing users of that optional argument, both in Spectrum
resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh
to not pass a now-unused argument.

We've added 6 non-merge commits during the last 8 day(s) which contain
a total of 6 files changed, 120 insertions(+), 20 deletions(-).

The main changes are:

1) Fix RCU usage in task_cls_state() for BPF programs using helpers like
   bpf_get_cgroup_classid_curr() outside of networking, from Charalampos
   Mitrodimas.

2) Fix a sockmap race between map_update and a pending workqueue from
   an earlier map_delete freeing the old psock where both pointed to the
   same psock->sk, from Jiayuan Chen.

3) Fix a data corruption issue when using bpf_msg_pop_data() in kTLS which
   failed to recalculate the ciphertext length, also from Jiayuan Chen.

4) Remove xdp_redirect_map{,_err} trace events since they are unused and
   also hide XDP trace events under CONFIG_BPF_SYSCALL, from Steven Rostedt.

validate_addr() checks whether the address returned by mmap() lies in the
low or high VA space, according to whether a high addr hint was passed or
not.  The fix commit mentioned below changed the code in such a way that
this function will always return failure when passed high_addr == 1; addr
will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr >
HIGH_ADDR_MARK)" and return failure.  Fix this.

also updated tools/testing/selftests/bpf/test_lru_map to match.

But that missed one case that passes with 4 cores, but fails at

Update test_lru_sanity3 to also adjust its expectation of target_free.

This time tested with 1, 4, 16, 64 and 384 cpu count.

fa6f092cc0 libbpf: Fix possible use-after-free for externs
The `name` field in `obj->externs` points into the BTF data at initial
open time. However, some functions may invalidate this after opening and
before loading (e.g. `bpf_map__set_value_size`), which results in
pointers into freed memory and undefined behavior.

The simplest solution is to simply `strdup` these strings, similar to
the `essent_name`, and free them at the same time.

In order to test this path, the `global_map_resize` BPF selftest is
modified slightly to ensure the presence of an extern, which causes this
test to fail prior to the fix. Given there isn't an obvious API or error
to test against, I opted to add this to the existing test as an aspect
of the resizing feature rather than duplicate the test.

9a96876e3c iommufd/selftest: Fix build warnings due to uninitialized mfd
Commit 869c788909 ("selftests: harness: Stop using setjmp()/longjmp()")
changed the harness structure. For some unknown reason, two build warnings
occur to the iommufd selftest:

iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns’:
iommufd.c:1807:17: warning: ‘mfd’ may be used uninitialized in this function
 1807 |                 close(mfd);
      |                 ^~~~~~~~~~
iommufd.c:1767:13: note: ‘mfd’ was declared here

iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns_copy’:
iommufd.c:1870:17: warning: ‘mfd’ may be used uninitialized in this function
 1870 |                 close(mfd);
      |                 ^~~~~~~~~~
iommufd.c:1819:13: note: ‘mfd’ was declared here
 1819 |         int mfd;
      |             ^~~

All the mfd have been used in the variant->file path only, so it's likely
a false alarm.

FWIW, the commit mentioned above does not cause this, yet it might affect
gcc in a certain way that resulted in the warnings. It is also found that
ading a dummy setjmp (which doesn't make sense) could mute the warnings:
https://lore.kernel.org/all/aEi8DV+ReF3v3Rlf@nvidia.com/

The job of this selftest is to catch kernel bug, while such warnings will
unlikely disrupt its role. Mute the warning by force initializing the mfd
and add an ASSERT_GT().

8186255705 iommufd/selftest: Fix iommufd_dirty_tracking with large hugepage sizes
The hugepage test cases of iommufd_dirty_tracking have the 64MB and 128MB
coverages. Both of them are smaller than the default hugepage size 512MB,
when CONFIG_PAGE_SIZE_64KB=y. However, these test cases have a variant of
using huge pages, which would mmap(MAP_HUGETLB) using these smaller sizes
than the system hugepag size. This results in the kernel aligning up the
smaller size to 512MB. If a memory was located between the upper 64/128MB
size boundary and the hugepage 512MB boundary, it would get wiped out:
https://lore.kernel.org/all/aEoUhPYIAizTLADq@nvidia.com/

Given that this aligning up behavior is well documented, we have no choice
but to allocate a hugepage aligned size to avoid this unintended wipe out.
Instead of relying on the kernel's internal force alignment, pass the same
size to posix_memalign() and map().

Also, fix the FIXTURE_TEARDOWN() misusing munmap() to free the memory from
posix_memalign(), as munmap() doesn't destroy the allocator meta data. So,
call free() instead.

632f55fa60 selftest: af_unix: Add tests for -ECONNRESET.
A new function resetpair() calls close() for the receiver and checks
the return value from recv() on the initial sender side.

not to touch TCP MSG_OOB code in the past.

e1ca44e85f af_unix: Add test for consecutive consumed OOB.
Let's add a test case where consecutive concumed OOB skbs stay

  #          FAIL  msg_oob.no_peek.ex_oob_ex_oob_oob
  not ok 12 msg_oob.no_peek.ex_oob_ex_oob_oob

After:

  #  RUN           msg_oob.no_peek.ex_oob_ex_oob_oob ...
  #            OK  msg_oob.no_peek.ex_oob_ex_oob_oob

cccfe09822 page_pool: import Jesper's page_pool benchmark
We frequently consult with Jesper's out-of-tree page_pool benchmark to
evaluate page_pool changes.

Import the benchmark into the upstream linux kernel tree so that (a)
we're all running the same version, (b) pave the way for shared
improvements, and (c) maybe one day integrate it with nipa, if possible.

Import bench_page_pool_simple from commit 35b1716d0c30 ("Add
page_bench06_walk_all"), from this repository:
https://github.com/netoptimizer/prototype-kernel.git

Changes done during upstreaming:
- Fix checkpatch issues.
- Remove the tasklet logic not needed.
- Move under tools/testing
- Create ksft for the benchmark.
- Changed slightly how the benchmark gets build. Out of tree, time_bench
  is built as an independent .ko. Here it is included in
  bench_page_pool.ko

Steps to run:

```
mkdir -p /tmp/run-pp-bench
make -C ./tools/testing/selftests/net/bench
make -C ./tools/testing/selftests/net/bench install INSTALL_PATH=/tmp/run-pp-bench
rsync --delete -avz --progress /tmp/run-pp-bench mina@$SERVER:~/
ssh mina@$SERVER << EOF
  cd ~/run-pp-bench && sudo ./test_bench_page_pool.sh
EOF
```

Note that by default, the Makefile will build the benchmark for the
currently installed kernel in /lib/modules/$(shell uname -r)/build. To
build against the current tree, do:

make KDIR=$(pwd) -C ./tools/testing/selftests/net/bench

Output (from Jesper):

```
sudo ./test_bench_page_pool.sh
(benchmark dmesg logs snipped)

Fast path results:
no-softirq-page_pool01 Per elem: 23 cycles(tsc) 6.571 ns

ptr_ring results:
no-softirq-page_pool02 Per elem: 60 cycles(tsc) 16.862 ns

slow path results:
no-softirq-page_pool03 Per elem: 265 cycles(tsc) 73.739 ns
```

Output (from me):

```
sudo ./test_bench_page_pool.sh
(benchmark dmesg logs snipped)

Fast path results:
no-softirq-page_pool01 Per elem: 11 cycles(tsc) 4.177 ns

ptr_ring results:
no-softirq-page_pool02 Per elem: 51 cycles(tsc) 19.117 ns

slow path results:
no-softirq-page_pool03 Per elem: 168 cycles(tsc) 62.469 ns
```

Results of course will vary based on hardware/kernel/configs, and some
variance may be there from run to run due to some noise.

2baa45432d selftests: drv-net: stats: use skip instead of xfail for unsupported features
XFAIL is considered a form of a pass by our CI. For HW devices returning
XFAIL for unsupported features is counter-productive because our CI
knows not to expect any HW test to pass until it sees 10 passes in a row.
If we return xfail the test shows up as pass even if the device doesn't
support the feature. netdevsim supports all features necessary for
the stats test so there is no concern about running the test in SW mode.

Make the test skip rather than xfail if driver doesn't support FEC or pause.

27390db959 testptp: add option to enable external timestamping edges
Some drivers (e.g. ice) don't enable any edges by default when external
timestamping is requested by the PTP_EXTTS_REQUEST ioctl, which makes
testptp -e unusable for testing hardware supported by these drivers.

Add -E option to specify if the rising, falling, or both edges should
be enabled by the ioctl.

14966a8df7 selftest: add selftest for anycast notifications
This commit adds a new kernel selftest to verify RTNLGRP_IPV6_ACADDR
notifications. The test works by adding/removing a dummy interface,
enabling packet forwarding, and then confirming that user space can
correctly receive anycast notifications.

The test relies on the iproute2 version to be 6.13+.

Tested by the following command:
$ vng -v --user root --cpus 16 -- \
make -C tools/testing/selftests TARGETS=net
TEST_PROGS=rtnetlink_notification.sh \
TEST_GEN_PROGS="" run_tests

CONFIG_UPROBES is enabled by CONFIG_UPROBE_EVENTS, which gets enabled by
CONFIG_FTRACE. Therefore add these configs to selftests/mm/config so that
CI systems can include this config in the kernel build. To be completely
safe, add CONFIG_PROFILING too, to enable the dependency chain
PROFILING -> PERF_EVENTS -> UPROBE_EVENTS -> UPROBES.

5c8013ae2e Including fixes from wireless. The ath12k fix to avoid FW crashes
requires adding support for a number of new FW commands so
 it's quite large in terms of LoC. The rest is relatively small.
 
 Current release - fix to a fix:
 
  - ptp: fix breakage after ptp_vclock_in_use() rework
 
 Current release - regressions:
 
  - openvswitch: allocate struct ovs_pcpu_storage dynamically, static
    allocation may exhaust module loader limit on smaller systems
 
 Previous releases - regressions:
 
  - tcp: fix tcp_packet_delayed() for peers with no selective ACK support
 
 Previous releases - always broken:
 
  - wifi: ath12k: don't activate more links than firmware supports
 
  - tcp: make sure sockets open via passive TFO have valid NAPI ID
 
  - eth: bnxt_en: update MRU and RSS table of RSS contexts on queue reset,
    prevent Rx queues from silently hanging after queue reset
 
  - NFC: uart: set tty->disc_data only in success path
