be enough to solve it.

The test is supposed to observe that the 'clash_resolve' stat counter
incremented (i.e., the code path was covered).
This check was incorrect, 'conntrack -S' needs to be called in the
revevant namespace, not the initial netns.
The clash resolution logic in conntrack is only exercised when multiple
packets with the same udp quadruple race. Depending on kernel config,
number of CPUs, scheduling policy etc. this might not trigger even
after several retries. Thus the script eventually returns SKIP if the
retry count is exceeded.
The udpclash tool with also exit with a failure if it did not observe
the expected number of replies.
In the script, make a note of this but do not fail anymore, just check if
the clash resolution logic triggered after all.
Remove the 'single-core' test: while unlikely, with preemptible kernel it
should be possible to also trigger clash resolution logic.
With this change the test will either SKIP or pass.
Hard error could be restored later once its clear whats going on, so
also dump 'conntrack -S' when some packets went missing to see if
conntrack dropped them on insert.

bpf: Reject %p% format string in bprintf-like helpers
Initial __arena global variable support implementation in libbpf
contains a bug: it remembers struct bpf_map pointer for arena, which is
used later on to process relocations. Recording this pointer is
problematic because map pointers are not stable during ELF relocation
collection phase, as an array of struct bpf_map's can be reallocated,
invalidating all the pointers. Libbpf is dealing with similar issues by
using a stable internal map index, though for BPF arena map specifically
this approach wasn't used due to an oversight.
The resulting behavior is non-deterministic issue which depends on exact
layout of ELF object file, number of actual maps, etc. We didn't hit
this until very recently, when this bug started triggering crash in BPF
CI when validating one of sched-ext BPF programs.
The fix is rather straightforward: we just follow an established pattern
of remembering map index (just like obj->kconfig_map_idx, for example)
instead of `struct bpf_map *`, and resolving index to a pointer at the
point where map information is necessary.
While at it also add debug-level message for arena-related relocation
resolution information, which we already have for all other kinds of
maps.

More code here than I would have liked. That said, better now than
next week. Nothing particularly scary stands out. The improvement to
the OpenVPN input validation is a bit large but better get them in
before the code makes it to a final release. Some of the changes
we got from sub-trees could have been split better between the fix
and -next refactoring, IMHO, that has been communicated.
We have one known regression in a TI AM65 board not getting link.
The investigation is going a bit slow, a number of people are on
vacation. We'll try to wrap it up, but don't think it should hold
up the release.
Current release - fix to a fix:
- Bluetooth: L2CAP: fix attempting to adjust outgoing MTU, it broke
some headphones and speakers
Current release - regressions:
- wifi: ath12k: fix packets received in WBM error ring with REO LUT
enabled, fix Rx performance regression
- wifi: iwlwifi:
- fix crash due to a botched indexing conversion
- mask reserved bits in chan_state_active_bitmap, avoid FW assert()
Current release - new code bugs:
- nf_conntrack: fix crash due to removal of uninitialised entry
- eth: airoha: fix potential UaF in airoha_npu_get()
Previous releases - regressions:
- net: fix segmentation after TCP/UDP fraglist GRO
- af_packet: fix the SO_SNDTIMEO constraint not taking effect and
a potential soft lockup waiting for a completion
- rpl: fix UaF in rpl_do_srh_inline() for sneaky skb geometry
- virtio-net: fix recursive rtnl_lock() during probe()
- eth: stmmac: populate entire system_counterval_t in get_time_fn()
- eth: libwx: fix a number of crashes in the driver Rx path
- hv_netvsc: prevent IPv6 addrconf after IFF_SLAVE lost that meaning
Previous releases - always broken:
- mptcp: fix races in handling connection fallback to pure TCP
- rxrpc: assorted error handling and race fixes
- sched: another batch of "security" fixes for qdiscs (QFQ, HTB)
- tls: always refresh the queue when reading sock, avoid UaF
- phy: don't register LEDs for genphy, avoid deadlock
- Bluetooth: btintel: check if controller is ISO capable on
btintel_classify_pkt_type(), work around FW returning incorrect
capabilities
Misc:
- make OpenVPN Netlink input checking more strict before it makes it
to a final release
- wifi: cfg80211: remove scan request n_channels __counted_by, its only

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.

hardcoded. With the change in place to make ring sysfs node actually
reflect the size of underlying ring buffer, it is safe to get the size

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)

Add a dedicated test to exercise conntrack clash resolution path.
Test program emits 128 identical udp packets in parallel, then reads
back replies from socat echo server.
Also check (via conntrack -S) that the clash path was hit at least once.
Due to the racy nature of the test its possible that despite the
threaded program all packets were processed in-order or on same cpu,
emit a SKIP warning in this case.
Two tests are added:
- one to test the simpler, non-nat case
- one to exercise clash resolution where packets
might have different nat transformations attached to them.

Extend the resize test:
- continuously dump table both via /proc and ctnetlink interfaces while
table is resized in a loop.
- if socat is available, send udp packets in additon to ping requests.
- increase/decrease the icmp and udp timeouts while resizes are happening.
This makes sure we also exercise the 'ct has expired' check that happens
on conntrack lookup.

/net/tools/testing/selftests/net/forwarding/../lib.sh: line 315: shift: shift count out of range
This happens because an extra shift is executed even after all arguments
have been consumed. Remove the last shift in log_test_result() to avoid
this warning.

The previous patch fixes a bug that prevented the creation of the
default IPv6 multicast route (ff00::/8) for some GRE devices. Now let's
extend the GRE IPv6 selftests to cover this case.
Also, rename check_ipv6_ll_addr() to check_ipv6_device_config() and
adapt comments and script output to take into account the fact that
we're not limited to link-local address generation.

The hv_fcopy_uio_daemon fails to correctly handle file copy requests
from Windows hosts (e.g. via Copy-VMFile) due to wchar_t size
differences between Windows and Linux. On Linux, wchar_t is 32 bit,
whereas Windows uses 16 bit wide characters.
Fix this by ensuring that file transfers from host to Linux guest
succeed with correctly decoded file names and paths.
- Treats file name and path as __u16 arrays, not wchar_t*.
- Allocates fixed-size buffers (W_MAX_PATH) for converted strings
instead of using malloc.
- Adds a check for target path length to prevent snprintf() buffer
overflow.

BITS_PER_LONG does not exist in UAPI headers, so can't be used by the UAPI
__GENMASK(). Instead __BITS_PER_LONG needs to be used.
When __GENMASK() was introduced in commit 3c7a8e190b ("uapi: introduce uapi-friendly macros for GENMASK"),
the code was fine. A broken revert in 1e7933a575 ("uapi: Revert "bitops: avoid integer overflow in GENMASK(_ULL)"")
introduced the incorrect usage of BITS_PER_LONG.
That was fixed in commit 11fcf36850 ("uapi: bitops: use UAPI-safe variant of BITS_PER_LONG again").
But a broken sync of the kernel headers with the tools/ headers in
commit fc92099902 ("tools headers: Synchronize linux/bits.h with the kernel sources")
undid the fix.
Reapply the fix and while at it also fix the tools header.

sys_futex_wait() expects a struct __kernel_timespec pointer for the

old_timespec32 when compiled for 32-bit architectures, unless they use
64-bit timespecs already.
Make it work for all variants by converting the provided timespec value
into a local struct __kernel_timespec and provide a pointer to it to the
syscall. This is a pointless operation for 64-bit, but this is not a
hotpath operation, so keep it simple.

Trying to compile an x86 kernel on big endian results in this error:
net/ipv4/netfilter/iptable_nat.o: warning: objtool: iptable_nat_table_init+0x150: Unknown annotation type: 50331648
make[5]: *** [scripts/Makefile.build:287: net/ipv4/netfilter/iptable_nat.o] Error 255
Reason is a missing endian conversion in read_annotate().
Add the missing conversion to fix this.
Fixes: 2116b349e2 ("objtool: Generic annotation infrastructure")
