jira LE-3207 feature tools_hv commit-author Shradha Gupta <shradhagupta@linux.microsoft.com> commit a9c0b33 Allow the KVP daemon to log the KVP updates triggered in the VM with a new debug flag(-d). When the daemon is started with this flag, it logs updates and debug information in syslog with loglevel LOG_DEBUG. This information comes in handy for debugging issues where the key-value pairs for certain pools show mismatch/incorrect values. The distro-vendors can further consume these changes and modify the respective service files to redirect the logs to specific files as needed.

jira SECO-478 RFBugFix: FUSE commit-author Miklos Szeredi <mszeredi@redhat.com> commit b4c173d Fuse allows the value of a symlink to change and this property is exploited by some filesystems (e.g. CVMFS). It has been observed, that sometimes after changing the symlink contents, the value is truncated to the old size. This is caused by fuse_getattr() racing with fuse_reverse_inval_inode(). fuse_reverse_inval_inode() updates the fuse_inode's attr_version, which results in fuse_change_attributes() exiting before updating the cached attributes This is okay, as the cached attributes remain invalid and the next call to fuse_change_attributes() will likely update the inode with the correct values. The reason this causes problems is that cached symlinks will be returned through page_get_link(), which truncates the symlink to inode->i_size. This is correct for filesystems that don't mutate symlinks, but in this case it causes bad behavior. The solution is to just remove this truncation. This can cause a regression in a filesystem that relies on supplying a symlink larger than the file size, but this is unlikely. If that happens we'd need to make this behavior conditional.

jira SECO-478 RFBugFix: FUSE commit-author Luis Henriques <luis@igalia.com> commit 2396356 upstream-diff | conflict in fs/fuse/dir.c due to missing this piece: d701902 - fuse: return correct dentry for ->mkdir Which is a part of a larger changeset here that we're not going to take: https://lore.kernel.org/all/20250227013949.536172-1-neilb@suse.de/ | Additionally this bumps the Kernel FUSE API minor version from 41 to 44. The interface into via fuse3 currently in Rocky 10.1 is limited to API 38 anyways at 3.16.2. | There is a build conflict due to a major rewrite of the d_revalidate calls which now includes the parent directory being passed. 5be1fa8 Pass parent directory inode and expected name to ->d_revalidate() In this case we can use the dentry->i_sb because we only need the superblock for get_fuse_conn_super(). Currently userspace is able to notify the kernel to invalidate the cache for an inode. This means that, if all the inodes in a filesystem need to be invalidated, then userspace needs to iterate through all of them and do this kernel notification separately. This patch adds the concept of 'epoch': each fuse connection will have the current epoch initialized and every new dentry will have it's d_time set to the current epoch value. A new operation will then allow userspace to increment the epoch value. Every time a dentry is d_revalidate()'ed, it's epoch is compared with the current connection epoch and invalidated if it's value is different.

jira KERNEL-1217 commit-author Jordan Rhee <jordanrhee@google.com> commit 6bf1457 upstream-diff RLC 10 predates the page-pool conversion and has no gve_free_buffer(); the freed buffer goes through gve_enqueue_buf_state(rx, &rx->dqo.recycled_buf_states, buf_state), the same form this tree's rx error path uses, which is what upstream's helper reduces to on non-page-pool queues. When header split is enabled and a header-only packet is received such as a pure TCP ACK, GVE will indicate an RX SKB with a zero-length fragment. If this SKB is then hairpinned and sent back out, the GVE TX path will emit a zero-length descriptor. Hardware considers this an illegal descriptor and stops the queue, causing a TX timeout and interface reset. Fix it by not adding the zero-length skb frag.

cve CVE-2026-68376 commit-author Xin Long <lucien.xin@gmail.com> commit e0b5252 The auth_hmacs array in struct sctp_cookie is supposed to store a complete SCTP_AUTH_HMAC_ALGO parameter, which consists of a struct sctp_paramhdr followed by N HMAC identifiers. However, the array size was calculated using an extra 2 bytes instead of sizeof(struct sctp_paramhdr), which is 4 bytes. When four HMAC identifiers are configured, the HMAC-ALGO parameter stored in the endpoint is larger than the auth_hmacs buffer in the cookie. As a result, sctp_association_init() copies beyond the end of auth_hmacs when initializing the association, corrupting the adjacent auth_chunks field. This can lead to an invalid HMAC identifier being accepted and later cause an out-of-bounds read in sctp_auth_get_hmac().

cve CVE-2026-46165 commit-author Ilya Maximets <i.maximets@ovn.org> commit aa69918 vports are used concurrently and protected by RCU, so netdev_put() must happen after the RCU grace period. So, either in an RCU call or after the synchronize_net(). The rtnl_delete_link() must happen under RTNL and so can't be executed in RCU context. Calling synchronize_net() while holding RTNL is not a good idea for performance and system stability under load in general, so calling netdev_put() in RCU call is the right solution here. However, when the device is deleted, rtnl_unlock() will call netdev_run_todo() and block until all the references are gone. In the current code this means that we never reach the call_rcu() and the vport is never freed and the reference is never released, causing a self-deadlock on device removal. Fix that by moving the rcu_call() before the rtnl_unlock(), so the scheduled RCU callback will be executed when synchronize_net() is called from the rtnl_unlock()->netdev_run_todo() while the RTNL itself is already released.

A malformed inner destination-options header can then make the HAO lookup and address swap run past the end of the quoted packet and corrupt skb_shared_info.

Op codes that have neither payload nor op code headers are not modified either (FUSE_READLINK and FUSE_DESTROY). FUSE_BATCH_FORGET already has the header in the right place, but is not using fuse_copy_args - as -over-uring is currently not handling forgets it does not matter for now, but header separation will later need special attention for that op code.

jira SECO-478 RFE: FUSE_IO_URING commit-author Bernd Schubert <bschubert@ddn.com> commit 4a9bfb9 On teardown struct file_operations::uring_cmd requests need to be completed by calling io_uring_cmd_done(). Not completing all ring entries would result in busy io-uring tasks giving warning messages in intervals and unreleased struct file. Additionally the fuse connection and with that the ring can only get released when all io-uring commands are completed. Completion is done with ring entries that are a) in waiting state for new fuse requests - io_uring_cmd_done is needed b) already in userspace - io_uring_cmd_done through teardown is not needed, the request can just get released. If fuse server is still active and commits such a ring entry, fuse_uring_cmd() already checks if the connection is active and then complete the io-uring itself with -ENOTCONN. I.e. special handling is not needed. This scheme is basically represented by the ring entry state FRRS_WAIT and FRRS_USERSPACE. Entries in state: - FRRS_INIT: No action needed, do not contribute to ring->queue_refs yet - All other states: Are currently processed by other tasks, async teardown is needed and it has to wait for the two states above. It could be also solved without an async teardown task, but would require additional if conditions in hot code paths. Also in my personal opinion the code looks cleaner with async teardown.

When the kernel is booted with fips=1, the RNG exposed to userspace is hijacked away from the CRNG and redirects to crypto_devrandom_read_iter(), which utilizes the DRBG. Notably, crypto_devrandom_read_iter() maintains just two global DRBG instances _for the entire system_, and the two instances serve separate request types: one instance for GRND_RANDOM requests (crypto_reseed_rng), and one instance for non-GRND_RANDOM requests (crypto_default_rng). So in essence, for requests of a single type, there is just one global RNG for all CPUs in the entire system, which scales _very_ poorly. To make matters worse, the temporary buffer used to ferry data between the DRBG and userspace is woefully small at only 256 bytes, which doesn't do a good job of maximizing throughput from the DRBG. This results in lost performance when userspace requests >256 bytes; it is observed that DRBG throughput improves by 70% on an i9-13900H when the buffer size is increased to 4096 bytes (one page). Going beyond the size of one page up to the DRBG maximum request limit of 65536 bytes produces diminishing returns of only 3% improved throughput in comparison. And going below the size of one page produces progressively less throughput at each power of 2: there's a 5% loss going from 4096 bytes to 2048 bytes and a 9% loss going from 2048 bytes to 1024 bytes. Thus, this implements per-CPU DRBG instances utilizing a page-sized buffer for each CPU to utilize the DRBG itself more effectively. On top of that, for non-GRND_RANDOM requests, the DRBG's operations now occur under a local lock that disables preemption on non-PREEMPT_RT kernels, which not only keeps each CPU's DRBG instance isolated from another, but also improves temporal cache locality while the DRBG actively generates a new string of random bytes. Prefaulting one user destination page at a time is also employed to prevent a DRBG instance from getting blocked on page faults, thereby maximizing the use of the DRBG so that the only bottleneck is the DRBG itself.

It is technically a risk to permit extrng registration by modules after kernel init completes. Since there is only one user of the extrng interface and it is imperative that it is the _only_ registered extrng for FIPS compliance, restrict the extrng registration interface to only permit registration during kernel init and only from built-in drivers. This also eliminates the risks associated with the extrng interface itself being designed to solely accommodate a single registration, which would therefore permit the registered extrng to be overridden or even removed by an unrelated module.

In FIPS mode, the DRBG must take precedence over all stdrng algorithms. The only problem standing in the way of this is that a different stdrng algorithm could get registered and utilized before the DRBG is registered, and since crypto_alloc_rng() only allocates an stdrng algorithm when there's no existing allocation, this means that it's possible for the wrong stdrng algorithm to remain in use indefinitely. This issue is also often impossible to observe from userspace; an RNG other than the DRBG could be used somewhere in the kernel and userspace would be none the wiser. To ensure this can never happen, only allow stdrng instances from the DRBG to be registered when running in FIPS mode. This works since the previous commit forces the DRBG to be built into the kernel when CONFIG_CRYPTO_FIPS is enabled, so the DRBG's presence is guaranteed when fips_enabled is true.

The 6.18.y version of "crypto: rng - Implement fast per-CPU DRBG instances" picked up a few spots that use spaces where the ciqlts9_6 tree's version [1] uses tabs: the lock_default_rng() comment's numbered list, the line continuations in the unlock_local_rng() macro, and a brace in crypto_devrandom_read_iter(). A nearby block comment was also missing the space before its '*'. Fix them up. [1] b0c560a Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Sultan Alsawaf <sultan@ciq.com>
The per-CPU DRBG instances used to be torn down by crypto_del_default_rng() under del_pcpu_rwsem, and the read path took that rwsem as a reader to keep an instance from being freed out from under it. That machinery only made sense back when the extrng override could be unregistered and the DRBG could be built as a module. That's no longer the case. extrng registration is now restricted to init time from built-in drivers, and FIPS mode requires the DRBG to be built-in, so the registered DRBG can't be unregistered or swapped out. As such, the per-CPU instances are never torn down, and the deletion rwsem just adds a lock to the hot read path for no reason. Drop the deletion rwsem and crypto_del_pcpu_rng(), and stop freeing the per-CPU instances in crypto_del_default_rng(). Since the instances are permanent now, allocate their pages once at init time with __GFP_NOFAIL and ditch free_pcpu_inst() along with the failure paths in crypto_rng_init(); failing to install the RNG override in FIPS mode would be catastrophic, so the setup isn't allowed to fail anyway. This brings the per-CPU DRBG implementation in line with the ciqlts9_6 tree's version of "crypto: rng - Implement fast per-CPU DRBG instances" [1].

The fast per-CPU DRBG path computes its initial user destination address
straight from the iov_iter. For an ITER_IOVEC iter it reads iter_iov_addr()
and iter_iov_len() of the current segment, but when the iovec leads with
one or more zero-length segments, the current segment is one of those empty
entries. iter_iov_addr() then hands back the base of an empty segment,
which is whatever userspace put there: its base can be NULL or some other
unwritable address, since a zero-length segment is never actually touched.
Right after the setup, that address is prefaulted, and on a bogus base it
fails. A failed prefault on the very first address is treated as fatal, so
the whole read bails out to -EFAULT even though there are perfectly good
non-empty segments later in the iovec. This is reachable with something as
simple as readv() on /dev/urandom where the first iovec entry is {NULL, 0}.
Fix it by advancing the iterator by zero before reading the first address.
The iovec advance loop walks past every leading empty segment and stops at
the first non-empty one, and there's guaranteed to be such a segment
because iov_iter_count() is nonzero at this point. Empty segments that crop
up mid-stream are already skipped by the per-copy advance, so this only
needs to run once during setup.

While GUP pinning makes it possible to pin the page _backing_ a user address, it *doesn't* pin the page table entry (PTE) for that mapping. This means the pinned physical page can be separated from the user address it was backing, and even back a _different_ user address within the same process. PTE zapping naturally happens during memory reclaim when memory pressure is elevated, and can even be done directly by userspace via madvise(MADV_DONTNEED). Since the optimized per-CPU DRBG loop assumes copy_to_user_nofault() will always succeed on a GUP-pinned page, it immediately bails out when the nofault copy actually *does* fail for the reasons described above. This results in either fewer than requested random bytes copied or, more seriously, a spurious EFAULT returned to userspace when no random bytes were copied. As it turns out, there's no way to pin a PTE. That means it's not possible to guarantee a 100% success rate for the copy_to_user_nofault() attempt. Fix this by handling copy_to_user_nofault() errors correctly with a fall back to a faultable copy attempt outside of the RNG lock. In order to guarantee forward progress for the caller, an on-stack bounce buffer is used to copy up to 256 bytes of the generated random bytes whenever this happens rather than discarding the whole thing. There's no need to use GUP pinning anymore since there's no use for having a page pinned without pinning a PTE to go along with that page, hence the page pinning is eliminated which saves a software page table walk that was performed for _at least_ every destination page.

local_unlock() is supposed to take a percpu pointer, which it then offsets for the current CPU. The problem is that the per-CPU DRBG code passes local_unlock() a pointer that has *already been offset for the current CPU*, so the percpu offset gets added twice. `pcri` is the percpu pointer and `cri` is the offset `pcri` pointer for the current CPU; passing `cri` to local_unlock() results in the current CPU's offset getting added again and thus the resulting pointer is garbage. This went unnoticed at runtime because local_unlock() only dereferences that pointer on PREEMPT_RT or CONFIG_DEBUG_LOCK_ALLOC=y kernels. The pointer is never actually used otherwise. This also went unnoticed at compile time because, for x86_64, __percpu only expands to something on GCC 14+; __percpu is otherwise an empty macro. So there's no pointer type mismatch detected at compile time on older GCC versions. On GCC 14+, the following compile error occurs: ../crypto/rng.c: In function 'lock_default_rng': ../include/linux/percpu-defs.h:221:45: error: initialization from pointer to non-enclosed address space Fix it by using __local_unlock() instead, which eliminates the duplicate per-CPU offset addition. While using local_unlock() with `pcri` also works, using `cri` with __local_unlock() is leaner because it doesn't need to redo the offset addition, saving an instruction on kernels that actually use the pointer.

A per-thread CPU timer holds a reference to the PID of the thread it is attached to and, while it is armed, its node is queued in that thread's posix_cputimers. The task is looked up by that PID. When a non-leader thread exec()s, de_thread() changes which task owns that PID. pid_task(timer->it.cpu.pid, PIDTYPE_PID) then returns NULL, but the node is still queued on tsk, which is alive. timer_lock_sighand() takes a failed lookup to mean that the node is already dequeued, so it has nothing to undo. begin_new_exec() calls posix_cpu_timers_exit(me) right after exec_task_namespaces() and that removes the leftover node, so the state normally stays invisible. But bprm->point_of_no_return is set before de_thread(), so if unshare_files(), set_mm_exe_file(), exec_mmap() or exec_task_namespaces() fails, the task dies before it gets there. exit_itimers() then frees the k_itimer while its node is still queued, and reaping tsk later erases that freed node from the rbtree.

cve-pre CVE-2026-98256 commit-author Frederic Weisbecker <frederic@kernel.org> commit 63dffec A sigqueue belonging to a posix timer, which target is not a specific thread but a whole thread group, is preferrably targeted to the current task if it is part of that thread group. However nothing prevents a posix timer event from queueing such a sigqueue from a reaped yet running task. The interruptible code space between exit_notify() and the final call to schedule() is enough for posix_timer_fn() hrtimer to fire. If that happens while the current task is part of the thread group target, it is proposed to handle it but since its sighand pointer may have been cleared already, the sigqueue is dropped even if there are other tasks running within the group that could handle it. As a result posix timers with thread group wide target may miss signals when some of their threads are exiting. Fix this with verifying that the current task hasn't been through exit_notify() before proposing it as a preferred target so as to ensure that its sighand is still here and stable. complete_signal() might still reconsider the choice and find a better target within the group if current has passed retarget_shared_pending() already.

If the timer signal is blocked, its sigqueue stays queued on the leader's task::pending. The next expiry of that timer can then run while release_task() flushes the queue. posixtimer_send_sigqueue() checks whether the sigqueue is already queued with a plain list_empty(), which only reads list_head::next. list_del_init() is not atomic and INIT_LIST_HEAD() stores list_head::next before list_head::prev, so the check can pass in between. list_add_tail() queues the entry on the task::pending of the live thread, and the list_head::prev store from the flush then overwrites the list_head::prev link that list_add_tail() has just set. __flush_itimer_signals() does not undo that either. With list_head::prev pointing at the entry itself, its list_del_init() only stores the same values again, so the entry is not removed from the list. It is still there after the last reference is dropped and the timer is freed by RCU, and the list_add_tail() of a later tgkill() follows that list_head::prev into the freed timer. This problem surfaced with the recent commit which moved the sigqueue flush out of the sighand lock held region. Hyonwoo proposed to fix this by using list_del_init_careful(), but that just papers over the problem. After some disucssions and various attempts to solve it, Eric pointed out that there is no reason to flush task::pending late in release_task() and it should be done in exit_signals() already. As nothing can collect and deliver signals which are queued in a dying task's pending queue, there is no reason to delay it further. But it has to be ensured that no signals can be queued into it after that point. exit_signals() sets PF_EXITING in task::flags, which can be used as an indicator for this. Cure it by: - Preventing signal queueing for task private signals (PIDTYPE_PID) when the task has PF_EXITING set in __send_signal_locked() and in posixtimer_send_sigqueue(). - Protecting the unlocked setting of PF_EXITING in exit_signals() for the task group empty and the group exit case with sighand lock - Flushing task::pending signals right there. Optimize that by moving the whole pending list to an on-stack list head under sighand lock and free the signals without the lock held. There has been quite some discussion about the lockless flush and the non-leader exec case on weakly ordered systems. The problem is that a third party which tries to send a posix timer signal relies on the PID lookup to find the target task and that lookup might result in the new leader when the signal was originaly directed to the old leader. In case that the signal was queued on the old leader then the lockless flush raised a concern over the following situation: old_leader new_leader third party A: flush_list() // list_del_init() stores to sigqueue LOCK (tasklist) old_leader->exit_state = EXIT_ZOMBIE; B: UNLOCK (tasklist) C: LOCK (tasklist) if (old_leader->exit_state) transfer_tids() D: store PID posix_timer_send_sigqueue() // Observes #D so t = new_leader E: t = get_target() F: LOCK (sighand) G: if (list_empty(sigqueue)) list_add(sigqueue) The concern was that the third party might observe #D but not observe #A and therefore would proceed to #G while the list_del() stores (#A) in flush_list() are not visible yet, which could result in list corruption. That would be possible if looking at it solely from a RELEASE+ACQUIRE ordering point of view, but B-C is a UNLOCK+LOCK hand-over, which is not the same as RELEASE+ACQUIRE: RELEASE+ACQUIRE: RCpc, only the CPUs involved agree on the ordering UNLOCK+LOCK: RCtso, the hand-over is store-ordering As B-C is UNLOCK+LOCK, which is RCtso and that does impose store order, A stores must happen before the D store. Combine with E-F, which has a data dependency from the LOAD to the LOCK and thereby constraints later LOADs, those sigqueue loads in G that come after F must in fact observe the A stores.
