Pull pidfs updates from Christian Brauner:
- persistent info
Persist exit and coredump information independent of whether anyone
currently holds a pidfd for the struct pid.
The current scheme allocated pidfs dentries on-demand repeatedly.
This scheme is reaching it's limits as it makes it impossible to pin
information that needs to be available after the task has exited or
coredumped and that should not be lost simply because the pidfd got
closed temporarily. The next opener should still see the stashed
information.
This is also a prerequisite for supporting extended attributes on
pidfds to allow attaching meta information to them.
If someone opens a pidfd for a struct pid a pidfs dentry is allocated
and stashed in pid->stashed. Once the last pidfd for the struct pid
is closed the pidfs dentry is released and removed from pid->stashed.
So if 10 callers create a pidfs dentry for the same struct pid
sequentially, i.e., each closing the pidfd before the other creates a
new one then a new pidfs dentry is allocated every time.
Because multiple tasks acquiring and releasing a pidfd for the same
struct pid can race with each another a task may still find a valid
pidfs entry from the previous task in pid->stashed and reuse it. Or
it might find a dead dentry in there and fail to reuse it and so
stashes a new pidfs dentry. Multiple tasks may race to stash a new
pidfs dentry but only one will succeed, the other ones will put their
dentry.
The current scheme aims to ensure that a pidfs dentry for a struct
pid can only be created if the task is still alive or if a pidfs
dentry already existed before the task was reaped and so exit
information has been was stashed in the pidfs inode.
That's great except that it's buggy. If a pidfs dentry is stashed in
pid->stashed after pidfs_exit() but before __unhash_process() is
called we will return a pidfd for a reaped task without exit
information being available.
The pidfds_pid_valid() check does not guard against this race as it
doens't sync at all with pidfs_exit(). The pid_has_task() check might
be successful simply because we're before __unhash_process() but
after pidfs_exit().
Introduce a new scheme where the lifetime of information associated
with a pidfs entry (coredump and exit information) isn't bound to the
lifetime of the pidfs inode but the struct pid itself.
The first time a pidfs dentry is allocated for a struct pid a struct
pidfs_attr will be allocated which will be used to store exit and
coredump information.
If all pidfs for the pidfs dentry are closed the dentry and inode can
be cleaned up but the struct pidfs_attr will stick until the struct
pid itself is freed. This will ensure minimal memory usage while
persisting relevant information.
The new scheme has various advantages. First, it allows to close the
race where we end up handing out a pidfd for a reaped task for which
no exit information is available. Second, it minimizes memory usage.
Third, it allows to remove complex lifetime tracking via dentries
when registering a struct pid with pidfs. There's no need to get or
put a reference. Instead, the lifetime of exit and coredump
information associated with a struct pid is bound to the lifetime of
struct pid itself.
- extended attributes
Now that we have a way to persist information for pidfs dentries we
can start supporting extended attributes on pidfds. This will allow
userspace to attach meta information to tasks.
One natural extension would be to introduce a custom pidfs.* extended
attribute space and allow for the inheritance of extended attributes
across fork() and exec().
The first simple scheme will allow privileged userspace to set
trusted extended attributes on pidfs inodes.
- Allow autonomous pidfs file handles
Various filesystems such as pidfs and drm support opening file
handles without having to require a file descriptor to identify the
filesystem. The filesystem are global single instances and can be
trivially identified solely on the information encoded in the file
handle.
This makes it possible to not have to keep or acquire a sentinal file
descriptor just to pass it to open_by_handle_at() to identify the
filesystem. That's especially useful when such sentinel file
descriptor cannot or should not be acquired.
For pidfs this means a file handle can function as full replacement
for storing a pid in a file. Instead a file handle can be stored and
reopened purely based on the file handle.
Such autonomous file handles can be opened with or without specifying
a a file descriptor. If no proper file descriptor is used the
FD_PIDFS_ROOT sentinel must be passed. This allows us to define
further special negative fd sentinels in the future.
Userspace can trivially test for support by trying to open the file
handle with an invalid file descriptor.
- Allow pidfds for reaped tasks with SCM_PIDFD messages
This is a logical continuation of the earlier work to create pidfds
for reaped tasks through the SO_PEERPIDFD socket option merged in
923ea4d4482b ("Merge patch series "net, pidfs: enable handing out
pidfds for reaped sk->sk_peer_pid"").

Pull mmap_prepare updates from Christian Brauner:
"Last cycle we introduce f_op->mmap_prepare() in c84bf6dd2b83 ("mm:
introduce new .mmap_prepare() file callback").
This is preferred to the existing f_op->mmap() hook as it does require
a VMA to be established yet, thus allowing the mmap logic to invoke
this hook far, far earlier, prior to inserting a VMA into the virtual
address space, or performing any other heavy handed operations.
This allows for much simpler unwinding on error, and for there to be a
single attempt at merging a VMA rather than having to possibly
reattempt a merge based on potentially altered VMA state.
Far more importantly, it prevents inappropriate manipulation of
incompletely initialised VMA state, which is something that has been
the cause of bugs and complexity in the past.
The intent is to gradually deprecate f_op->mmap, and in that vein this
series coverts the majority of file systems to using f_op->mmap_prepare.
Prerequisite steps are taken - firstly ensuring all checks for mmap
capabilities use the file_has_valid_mmap_hooks() helper rather than
directly checking for f_op->mmap (which is now not a valid check) and
secondly updating daxdev_mapping_supported() to not require a VMA
parameter to allow ext4 and xfs to be converted.
Commit bb666b7c2707 ("mm: add mmap_prepare() compatibility layer for
nested file systems") handles the nasty edge-case of nested file
systems like overlayfs, which introduces a compatibility shim to allow
f_op->mmap_prepare() to be invoked from an f_op->mmap() callback.
This allows for nested filesystems to continue to function correctly
with all file systems regardless of which callback is used. Once we
finally convert all file systems, this shim can be removed.
As a result, ecryptfs, fuse, and overlayfs remain unaltered so they
can nest all other file systems.
We additionally do not update resctl - as this requires an update to
remap_pfn_range() (or an alternative to it) which we defer to a later
series, equally we do not update cramfs which needs a mixed mapping
insertion with the same issue, nor do we update procfs, hugetlbfs,
syfs or kernfs all of which require VMAs for internal state and hooks.
We shall return to all of these later"

Pull coredump updates from Christian Brauner:
"This contains an extension to the coredump socket and a proper rework
of the coredump code.
- This extends the coredump socket to allow the coredump server to
tell the kernel how to process individual coredumps. This allows
for fine-grained coredump management. Userspace can decide to just
let the kernel write out the coredump, or generate the coredump
itself, or just reject it.
* COREDUMP_KERNEL
The kernel will write the coredump data to the socket.
* COREDUMP_USERSPACE
The kernel will not write coredump data but will indicate to the
parent that a coredump has been generated. This is used when
userspace generates its own coredumps.
* COREDUMP_REJECT
The kernel will skip generating a coredump for this task.
* COREDUMP_WAIT
The kernel will prevent the task from exiting until the coredump
server has shutdown the socket connection.
The flexible coredump socket can be enabled by using the "@@"
prefix instead of the single "@" prefix for the regular coredump
socket:
@@/run/systemd/coredump.socket
- Cleanup the coredump code properly while we have to touch it
anyway.
Split out each coredump mode in a separate helper so it's easy to
grasp what is going on and make the code easier to follow. The core

selftests: netfilter: tone-down conntrack clash test
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.

correctly on 64-bit kernels. sys_futex_wait() expects a struct __kernel_timespec for the timeout, but the selftest uses struct timespec, which is the original 32-bit non 2038 compliant variant. Fix it up by converting the callsite supplied timespec to a __kernel_timespec and hand that into the syscall. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmh81ykTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoaf3D/4rEvjK6jo6/YFXQF0mfArk1JgK2hje zNmF6xyvAFKmaVQmT35DB8vyeWchvIWlwxMYkAKDZfDlZfEU8mxY4HbHCyKaBlHj 52vwpvGxHPWCdiIgzee+y7asZ7OEUHXktxsbptsZ0KsvU+P+6OWZIKT3eySKmuhA FSIiiLD6SsU2UMvfIFuX7vMiI3IuhBoGlzXveJLQ3HBg90EfyzQY3ZS1yftjikDb d15TO2sWWKlHITGSWllS28JUlw5fKXKcrKwSVo5I0vETW/oD+YTKP8K1apir2mZ2 sfBlFQAWeDhcn/8r+K/6XCaGnrqguQvJJNu9K6e6T5p932hOtpou4dE297wLw2cn B08F+THgBgv9iO1gp5r97jR91aEbp6bf1K+5NljLXAY3Xk2yU1uyjJFIojdwE9Fq 7H/BBRceP7aaiEJJoIPeLCItx9uvunlxdd2R9b2E5XzoSYiO/iQCyAGyBpu5L1dm TvX4cTrlVs4orNnujDbqH2GkB3locXLtb9nZBFyj+RwCgg+gwTSSUrvxjDelE7LU /niUMwY4qZwlME6LO1gNOcG0yQYhdh0uYqXBzCfE+44IvihEjZIsgijNPCyObsTU WcbQBRphNgj6cN3ck9whz6XWerG+Oga4SpDJc7OSOL7l4uX294Rf3tm0YC0GHxA3 mDcs+p5ZStMnTA== =zIcB -----END PGP SIGNATURE----- Merge tag 'locking-urgent-2025-07-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking fix from Thomas Gleixner: "A single fix for the futex selftest code to make 32-bit user space work correctly on 64-bit kernels. sys_futex_wait() expects a struct __kernel_timespec for the timeout, but the selftest uses struct timespec, which is the original 32-bit non 2038 compliant variant.

Including fixes from Bluetooth, CAN, WiFi and Netfilter.
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
yeilding false positives

selftests/tc-testing: Create test cases for adding qdiscs to invalid qdisc 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) [1] https://lore.kernel.org/all/20250707210801.372995-1-victor@mojatatu.com/ [2] https://lore.kernel.org/netdev/d912cbd7-193b-4269-9857-525bee8bbb6a@gmail.com/ Signed-off-by: Victor Nogueira <victor@mojatatu.com> Link: https://patch.msgid.link/20250712145035.705156-1-victor@mojatatu.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

selftests: netfilter: add conntrack clash resolution test case
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.

selftests: netfilter: conntrack_resize.sh: extend resize test
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. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> |

/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

this warning.

selftests: Add IPv6 multicast route generation tests for GRE devices.
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.

selftests/futex: Convert 32-bit timespec to 64-bit version for 32-bit compatibility mode
sys_futex_wait() expects a struct __kernel_timespec pointer for the timeout, but the provided struct timespec pointer is of type struct 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.

selftests/kernfs: test xattr retrieval
Make sure that listxattr() returns zero and that getxattr() returns ENODATA when no extended attributs are set. Use /sys/kernel/warn_count as that always exists and is a read-only file.

selftests/mm: fix validate_addr() helper
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.

netlink: specs: ethtool: replace underscores with dashes in names
We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen replaces special chars in names)
but gives more uniform naming in Python.

selftests/bpf: adapt one more case in test_lru_map to the new target_free
The below commit that updated BPF_MAP_TYPE_LRU_HASH free target,
also updated tools/testing/selftests/bpf/test_lru_map to match.
But that missed one case that passes with 4 cores, but fails at
higher cpu counts.
Update test_lru_sanity3 to also adjust its expectation of target_free.
This time tested with 1, 4, 16, 64 and 384 cpu count.
