It's no longer user-selectable (and the default was already "y"), so
let's just drop it.
It was never really relevant to the wireguard selftests either way.

While at it, also run it under timeout(1) and fix the resize script

Jakub says:
nft_flowtable.sh is one of the most flake-atious test for netdev CI currently :(
The root cause is two-fold:
1. the failing part of the test is supposed to make sure that ip
fragments are forwarded for offloaded flows.
(flowtable has to pass them to classic forward path).
path mtu discovery for these subtests is disabled.
2. nft_flowtable.sh has two passes. One with fixed mtus/file size and
one where link mtus and file sizes are random.
The CI failures all have same pattern:
re-run with random mtus and file size: -o 27663 -l 4117 -r 10089 -s 54384840
[..]
PASS: dscp_egress: dscp packet counters match
FAIL: file mismatch for ns1 -> ns2
In some cases this error triggers a bit ealier, sometimes in a later
subtest:
re-run with random mtus and file size: -o 20201 -l 4555 -r 12657 -s 9405856
[..]
PASS: dscp_egress: dscp packet counters match
PASS: dscp_fwd: dscp packet counters match
2025/08/17 20:37:52 socat[18954] E write(7, 0x560716b96000, 8192): Broken pipe
FAIL: file mismatch for ns1 -> ns2
-rw------- 1 root root 9405856 Aug 17 20:36 /tmp/tmp.2n63vlTrQe
But all logs I saw show same scenario:
1. Failing tests have pmtu discovery off (i.e., ip fragmentation)
2. The test file is much larger than first-pass default (2M Byte)
3. peers have much larger MTUs compared to the 'network'.
These errors are very reproducible when re-running the test with
the same commandline arguments.
The timeout became much more prominent with
1d2fbaad7cd8 ("tcp: stronger sk_rcvbuf checks"): reassembled packets
typically have a skb->truesize more than double the skb length.
As that commit is intentional and pmtud-off with
large-tcp-packets-as-fragments is not normal adjust the test to use a
smaller file for the pmtu-off subtests.
While at it, add more information to pass/fail messages and
also run the dscp alteration subtest with pmtu discovery enabled.

- Ensure that page table destruction when a VM is destroyed gives an

- Fix AT S12 emulation to actually perform stage-2 translation when
necessary
- Avoid attempting vLPI irqbypass when GICv4 has been explicitly

RISC-V:
- Fix pte settings within kvm_riscv_gstage_ioremap()
- Fix comments in kvm_riscv_check_vcpu_requests()

Add a new command line option --no_ublk_fixed_fd that excludes the ublk
control device (/dev/ublkcN) from io_uring's registered files array.
When this option is used, only backing files are registered starting
from index 1, while the ublk control device is accessed using its raw
file descriptor.
Add ublk_get_registered_fd() helper function that returns the appropriate
file descriptor for use with io_uring operations.
Key optimizations implemented:
- Cache UBLKS_Q_NO_UBLK_FIXED_FD flag in ublk_queue.flags to avoid
reading dev->no_ublk_fixed_fd in fast path
- Cache ublk char device fd in ublk_queue.ublk_fd for fast access
- Update ublk_get_registered_fd() to use ublk_queue * parameter
- Update io_uring_prep_buf_register/unregister() to use ublk_queue *
- Replace ublk_device * access with ublk_queue * access in fast paths
Also pass --no_ublk_fixed_fd to test_stress_04.sh for covering
plain ublk char device mode.

FORCE_READ() converts input value x to its pointer type then reads from
address x. This is wrong. If x is a non-pointer, it would be caught it
easily. But all FORCE_READ() callers are trying to read from a pointer
and FORCE_READ() basically reads a pointer to a pointer instead of the
original typed pointer. Almost no access violation was found, except the
one from split_huge_page_test.
Fix it by implementing a simplified READ_ONCE() instead.

regression. New user tools releases will not use such a mode,
the old release with a new kernel now will have warning about
deprecated behavior, and we prepare to remove this legacy mode
after about a year later
- The rename in kernel causing user tools build failure, revert
the rename in mdp_superblock_s
- Fix a regression that interrupted resync can be shown as
recover from mdstat or sysfs
- Improve file size detection for loop, particularly for networked
file systems, by using getattr to get the size rather than the
cached inode size.
- Hotplug CPU lock vs queue freeze fix
- Lockdep fix while updating the number of hardware queues
- Fix stacking for PI devices

Test various combinations of zero-length records.
Unfortunately, kernel cannot be coerced into producing those,
so hardcode the ciphertext messages in the test.

Add a selftest to verify bonding behavior when `lacp_active` is set to `off`.
The test checks the following:
- The passive LACP bond should not send LACPDUs before receiving a partner's
LACPDU.
- The transmitted LACPDUs must not include the active flag.
- After transitioning to EXPIRED and DEFAULTED states, the passive side should
still not initiate LACPDUs.

We can use UFFD to easily assert invalid multi VMA moves, so do so,
asserting expected behaviour when VMAs invalid for a multi VMA operation
are encountered.
We assert both that such operations are not permitted, and that we do not
even attempt to move the first VMA under these circumstances.
We also assert that we can still move a single VMA regardless.
We then assert that a partial failure can occur if the invalid VMA appears
later in the range of multiple VMAs, both at the very next VMA, and also at
the end of the range.
As part of this change, we are using the is_range_valid() helper more
aggressively. Therefore, fix a bug where stale buffered data would hang
around on success, causing subsequent calls to is_range_valid() to
potentially give invalid results.
We simply have to fflush() the stream on success to resolve this issue.

To validate that, the test is now flushing endpoints after having set
new limits, and before checking them.

The CI has hit a couple of cases of:
RUN global.data_steal ...
tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1)
data_steal: Test terminated by timeout
FAIL global.data_steal
Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
to be causing issues in manual testing as well.

The test is implicitly assuming the device only has 2 queues.
A real device will likely have more. The exact problem is that
because NAPIs get added to the list from the head, the netlink
dump reports them in reverse order. So the naive napis[0] will
actually likely give us the _last_ NAPI, not the first one.
Re-enable all the NAPIs instead of hard-coding 2 in the test.
This way the NAPIs we operated on will always reappear,
doesn't matter where they were in the registration order.

Previous releases - always broken:
- packet: fix a race in packet_set_ring() and packet_notifier()
- ipv6: reject malicious packets in ipv6_gso_segment()
- sched: mqprio: fix stack out-of-bounds write in tc entry parsing
- net: drop UFO packets (injected via virtio) in udp_rcv_segment()
- eth: mlx5: correctly set gso_segs when LRO is used, avoid false
positive checksum validation errors
- netpoll: prevent hanging NAPI when netcons gets enabled
- phy: mscc: fix parsing of unicast frames for PTP timestamping
- a number of device tree / OF reference leak fixes"

Pull perf fixes from Thomas Gleixner:
"Perf fixes for perf_mmap() reference counting to prevent potential
reference count leaks which are caused by:
- VMA splits, which change the offset or size of a mapping, which
causes perf_mmap_close() to ignore the unmap or unmap the wrong
buffer.
- Several internal issues of perf_mmap(), which can cause reference
count leaks in the perf mmap, corrupt accounting or cause leaks in
perf drivers.
The main fix is to prevent VMA splits by implementing the
[may_]split() callback for vm operations.
The other issues are addressed by rearranging code, early returns on
failure and invocation of cleanups.
Also provide a selftest to validate the fixes.
The reference counting should be converted to refcount_t, but that
requires larger refactoring of the code and will be done once these
fixes are upstream"
