Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following batch contains Netfilter fixes for net:
1) Three patches to enhance conntrack selftests for resize and clash
resolution, from Florian Westphal.
2) Expand nft_concat_range.sh selftest to improve coverage from error
path, from Florian Westphal.
3) Hide clash bit to userspace from netlink dumps until there is a
good reason to expose, from Florian Westphal.
4) Revert notification for device registration/unregistration for
nftables basechains and flowtables, we decided to go for a better
way to handle this through the nfnetlink_hook infrastructure which
will come via nf-next, patch from Phil Sutter.
5) Fix crash in conntrack due to race related to SLAB_TYPESAFE_BY_RCU
that results in removing a recycled object that is not yet in the
hashes. Move IPS_CONFIRM setting after the object is in the hashes.
From Florian Westphal.

Some build environments for the selftests are not picking up the newly
added AT_HWCAP3 when using the libc headers, even with headers_install
(which we require already for the arm64 selftests). As a quick fix add
local definitions of the constant to tools use it, while auxvec.h is
installed with some toolchains it needs some persuasion to get picked up.

As BPF doesn't include any barrier instructions, smp_mb() is implemented
by doing a dummy value returning atomic operation. Such an operation
acts a full barrier as enforced by LKMM and also by the work in progress
BPF memory model.
If the returned value is not used, clang[1] can optimize the value
returning atomic instruction in to a normal atomic instruction which
provides no ordering guarantees.
Mark the variable as volatile so the above optimization is never
performed and smp_mb() works as expected.

The 'commit 35f96de04127 ("bpf: Introduce BPF token object")' added
BPF token as a new kind of BPF kernel object. And BPF_OBJ_GET_INFO_BY_FD
already used to get BPF object info, so we can also get token info with
this cmd.
One usage scenario, when program runs failed with token, because of
the permission failure, we can report what BPF token is allowing with

Add a basic selftest for the netpoll polling mechanism, specifically
targeting the netpoll poll() side.
The test creates a scenario where network transmission is running at
maximum speed, and netpoll needs to poll the NIC. This is achieved by:
1. Configuring a single RX/TX queue to create contention
2. Generating background traffic to saturate the interface
3. Sending netconsole messages to trigger netpoll polling
4. Using dynamic netconsole targets via configfs
5. Delete and create new netconsole targets after some messages
6. Start a bpftrace in parallel to make sure netpoll_poll_dev() is
called
7. If bpftrace exists and netpoll_poll_dev() was called, stop.
The test validates a critical netpoll code path by monitoring traffic
flow and ensuring netpoll_poll_dev() is called when the normal TX path
is blocked.
This addresses a gap in netpoll test coverage for a path that is
tricky for the network stack.

bpftrace is very useful for low level driver testing. perf or trace-cmd
would also do for collecting data from tracepoints, but they require
much more post-processing.
Add a wrapper for running bpftrace and sanitizing its output.
bpftrace has JSON output, which is great, but it prints loose objects
and in a slightly inconvenient format. We have to read the objects
line by line, and while at it return them indexed by the map name.

`vsock_do_ioctl` returns -ENOIOCTLCMD if an ioctl support is not
implemented, like for SIOCINQ before commit f7c722659275 ("vsock: Add
support for SIOCINQ ioctl"). In net/socket.c, -ENOIOCTLCMD is re-mapped
to -ENOTTY for the user space. So, our test suite, without that commit
applied, is failing in this way:
34 - SOCK_STREAM ioctl(SIOCINQ) functionality...ioctl(21531): Inappropriate ioctl for device
Return false in vsock_ioctl_int() to skip the test in this case as well,
instead of failing.

Jakub reported that the rtnetlink test for the preferred lifetime of an
address has become quite flaky. The issue started appearing around the 6.16
merge window in May, and the test fails with:
FAIL: preferred_lft addresses remaining
The flakiness might be related to power-saving behavior, as address
expiration is handled by a "power-efficient" workqueue.
To address this, use slowwait to check more frequently whether the address
still exists. This reduces the likelihood of the system entering a low-power
state during the test, improving reliability.

This commit prepares for the removal of SRCU-Lite by removing the SRCU-L
rcutorture scenario that tests it.
Both SRCU-lite and SRCU-fast provide faster readers by dropping the
smp_mb() call from their lock and unlock primitives, but incur a pair
of added RCU grace periods during the SRCU grace period. There is a
trivial mapping from the SRCU-lite API to that of SRCU-fast, so there
should be no transition issues.

The kvm.sh script places a testid.txt file in the top-level results
directory in order to identify the tree and commit that was tested.
This works well, but there are scripts other than kvm.sh that also create
results directories, and it would be good for them to also identify
exactly what was tested.
This commit therefore extracts the testid.txt generation to a new
mktestid.sh script so that it can be easily used elsewhere.

'struct thread' is task local structure, and the related code will become

Meantime pass 'ublk_thread *' to ublk_io_alloc_sqes(), and this way is

More importantly it helps much for removing the current ubq_daemon or

parents
As described in a previous commit [1], Lion's patch [2] revealed an ancient
bug in the qdisc API. Whenever a user tries to add a qdisc to an
invalid parent (not a class, root, or ingress qdisc), the qdisc API will
detect this after qdisc_create is called. Some qdiscs (like fq_codel, pie,
and sfq) call functions (on their init callback) which assume the parent is
valid, so qdisc_create itself may have caused a NULL pointer dereference in
such cases.
This commit creates 3 TDC tests that attempt to add fq_codel, pie and sfq
qdiscs to invalid parents
- Attempts to add an fq_codel qdisc to an hhf qdisc parent
- Attempts to add a pie qdisc to a drr qdisc parent
- Attempts to add an sfq qdisc to an inexistent hfsc classid (which would
belong to a valid hfsc qdisc)

I missed adding rss_api.py to the Makefile. The NIPA Makefile
checking script was scanning for shell scripts only, so it
didn't flag it either.

Prepare for bucket resume tests for established TCP sockets by creating
a program to immediately destroy and remove sockets from the TCP ehash
table, since close() is not deterministic.

Prepare for bucket resume tests for established TCP sockets by creating
established sockets. Collect socket fds from connect() and accept()
sides and pass them to test cases.

Prepare for bucket resume tests for established TCP sockets by making
the number of ehash buckets configurable. Subsequent patches force all
established sockets into the same bucket by setting ehash_buckets to
one.

Starting with Rust 1.89.0 (expected 2025-08-07), under
`CONFIG_RUST_DEBUG_ASSERTIONS=y`, `objtool` may report:
rust/kernel.o: warning: objtool: _R..._6kernel4pageNtB5_4Page8read_raw()
falls through to next function _R..._6kernel4pageNtB5_4Page9write_raw()
(and many others) due to calls to the `noreturn` symbol:
core::panicking::panic_nounwind_fmt
Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.
See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions")
for more details.
Cc: stable@vger.kernel.org # Needed in 6.12.y and later (Rust is pinned in older LTSs).

Add parentheses around loopback address check to fix up logic and make
the socket state filter configurable for the TCP socket iterators.
Iterators can skip the socket state check by setting ss to 0.
