btf_parse_struct_metas() walks user-supplied BTF during BPF_BTF_LOAD,
and btf_repeat_fields() expands repeatable fields from array elements
into the fixed BTF_FIELDS_MAX scratch array used by btf_parse_fields().
The remaining-capacity check performs the expanded field count calculation
in u32. A malformed BTF can wrap that calculation, causing the check to
pass even when the expanded field count exceeds the scratch array
capacity. The following memcpy() can then write past the end of the
array.
Use checked addition and multiplication before copying repeated fields
and reject impossible counts.

should then add or subtract task runnable_avg, but the arithmetic below

When building the kernel using the llvm-22.1.0-rust-1.93.1-x86_64
toolchain provided by kernel.org with ARCH=x86_64, the following symbols

ffffffff81827950 T <kernel::sync::completion::Completion>::wait_for_completion
These Rust methods are thin wrappers around the C completion helpers
`complete_all` and `wait_for_completion`. Mark them `#[inline]` to keep
the wrapper pattern consistent with other small Rust helper methods.

We have two pull requests on Rust synchronization primitives with 10+
patches in a row for recent cycles, so it makes sense to start the
effort of handling this area as a group.
Luckily for me, Gary Guo and Alice Ryhl agreed to help as
co-maintainers, and we also have a talented group of reviewers:
Lyude Paul started the SpinLockIrq work [1] and did an amazing job at
improving the design and implementation.
Daniel Almeida resolved the Lock<T: !Unpin> issue [2] and he did a fair
amount of reviews in areas related to synchronization primitives
already.
Onur Özkan started the ww_mutex work [3] and did an amazing job at
consolidating various design requirements and decisions.
Of course, this only reflects my own knowledge, and I believe they did
way more outside what I'm aware of ;-)
Note that having this MAINTAINERS entry is meant to bring more people
to help on the synchronization primitives in Rust, which means for patch
submissions and design discussion, please still involve the
corresponding maintainers (e.g. LOCKING and ATOMIC),
scripts/get_maintainers.pl should have this covered.

The LPI2C driver requests DMA channels using dma_request_chan(), but
never releases them in lpi2c_imx_remove(), resulting in DMA channel
leaks every time the driver is unloaded.
Additionally, when lpi2c_dma_init() successfully requests the TX DMA
channel but fails to request the RX DMA channel, the probe falls back
to PIO mode and completes successfully. Since probe succeeds, the devres
framework will not trigger any cleanup, leaving the TX DMA channel and
the memory allocated for the dma structure held for the lifetime of the
device even though DMA is never used.
Switch to devm_dma_request_chan() to let the device core manage DMA
channel lifetime automatically. Wrap all allocations within a devres
group so that devres_release_group() can release all partially acquired
resources when DMA init fails and probe continues in PIO mode.

A crafted NTFS3 disk image triggers an in-kernel infinite loop at
mount time, hanging the mounting thread and firing the soft-lockup
watchdog within ~22s on multi-CPU hosts (panic with
kernel.softlockup_panic=1). The bug is reachable from desktop USB
auto-mount on distributions where udisks2 routes the NTFS signature
to the in-tree ntfs3 driver (Arch family and an increasing fraction
of Fedora / openSUSE / RHEL deployments); CAP_SYS_ADMIN-class manual
mount elsewhere.
check_rstbl()'s second walker iterates the free-entry singly-linked
list headed by rt->first_free with no upper bound on iteration count:
for (off = ff; off;) {
if (off == RESTART_ENTRY_ALLOCATED)
return false;
off = le32_to_cpu(*(__le32 *)Add2Ptr(rt, off));
if (off > ts - sizeof(__le32))
return false;
}
The existing guards cover three exits: end-of-list (off == 0), the
in-use marker (off == RESTART_ENTRY_ALLOCATED), and out-of-bounds
(off > ts - sizeof(__le32)). None of the three prevents an
in-bounds cycle.
A crafted on-disk RESTART_TABLE whose free chain contains a
self-loop or A->B->A cycle whose offsets satisfy:
- in range [sizeof(struct RESTART_TABLE), ts - sizeof(__le32)]
- (off - sizeof(struct RESTART_TABLE)) % rsize == 0
passes all existing guards and spins the mount-time thread forever.
Reproduced in UML by hand-forging a 2 MB NTFS3 image whose journal
RESTART_TABLE first_free = 0x18 and whose entry at offset 0x18
stores 0x18 as its next pointer; mount of the forged image with
the in-tree ntfs3 driver never returns.
Bound the walker by rt->used. Each entry on a legitimate free
chain is unique, and the total slot count is ne = le16_to_cpu
(rt->used). A traversal that visits more than ne slots is by
construction malformed; reject it as a corrupt RESTART_TABLE.
After this patch, mount of the forged image returns with -EINVAL
and a log_replay failure message, and mkntfs-produced legitimate
images mount cleanly (verified in the same UML harness).

In do_action()'s UpdateRecordDataRoot (fslog.c:3489) and
UpdateRecordDataAllocation (fslog.c:3697) cases, the memmove
destination is `Add2Ptr(e, le16_to_cpu(e->view.data_off))`,
where e->view.data_off comes from an on-disk NTFS_DE inside
an INDEX_ROOT or INDEX_BUFFER. Neither case validates
view.data_off + dlen against e->size; the existing
check_if_index_root / check_if_alloc_index helpers walk the
entry chain and validate the entry's offset, but not its
internal view fields.
The neighbouring read sites (e.g., fs/ntfs3/index.c when
iterating view entries) check view.data_off + view.data_size
<= e->size. Apply the same bound at the two memmove sites.
Reproduced under UML+KASAN on mainline 8d90b09e6741 via
pr_warn-only probe instrumentation: with view.data_off forced
to 0xFFFC, the memmove writes 32 bytes past the end of the

convert_ltr_scale() emits an unconditional pr_warn() whenever an LTR row
encoded by hardware has a scale-factor field of 6 or 7 (reserved values
per the PCIe LTR ECN). The function is called twice per LTR row (snoop
+ non-snoop) by pmc_core_ltr_show(), which is invoked on every read of
/sys/kernel/debug/pmc_core/ltr_show as well as during certain platform
driver activity.
On a Meteor Lake laptop with an Intel AX210 Wi-Fi card, this produces
4-12 "Invalid LTR scale factor." lines per second in dmesg, with no
context to help identify which PMC IP / row carries the bad value.
Switch to pr_warn_once() so the warning still flags the spec violation
once per boot, and include the offending scale value in the message.
Identifying the originating LTR row would require restructuring the
caller's loop to perform the validity check itself; that is left as a
separate change.

The xfs_imap structure is embedded into the xfs_inode, which means the

As a side-effect the debugging check in xfs_imap() naturally now

The computed value is stored back in req->resblks and later passed

After the patch in the "Fixes" tag, the allocation of the "reply" skb
can happen either before or after locking the ovs_mutex.
However, error cleanups still follow the classical reversed order,
assuming "reply" is allocated before locking: it is freed after unlocking.
If "reply" allocation happens after locking the mutex and it fails,
"reply" is left with an ERR_PTR, and execution jumps to the correspondent
cleanup stage which will try to free an invalid pointer.
Fix this by setting the pointer to NULL after having saved its error
value.

Chuck Lever says:
====================
tls: receive-path fixes and clean-ups
I'd like to encourage in-kernel kTLS consumers (NFSD, NVMe/TCP) to
coalesce on the use of read_sock. While auditing read_sock for that
purpose, Hannes and Sabrina flagged a few rough edges in the receive
paths.
This series is a set of clean-ups, not a performance series. Async
batch decryption and its submit/deliver scaffolding were dropped
during previous review: async_capable is always false for TLS 1.3,
the version NFSD and NVMe/TCP both require, so async-related
improvements were unreachable for the in-kernel consumers this
work targets.
A subsequent series will introduce infrastructure to support
KeyUpdate for in-kernel kTLS consumers, which need to handle TLS
Alert messages that trigger a tlshd upcall.

While lock_sock is held, incoming TCP segments land on
sk->sk_backlog rather than sk->sk_receive_queue.
tls_rx_rec_wait() inspects only sk_receive_queue, so backlog
data remains invisible. For non-blocking callers (read_sock,
and recvmsg or splice_read with MSG_DONTWAIT) this causes a
spurious -EAGAIN. For blocking callers it forces an
unnecessary sleep/wakeup cycle.
Flush the backlog inside tls_rx_rec_wait() before checking
sk_receive_queue so the strparser can parse newly-arrived
segments immediately. On the next loop iteration
tls_read_flush_backlog() may redundantly flush, but this
path is cold and the cost is negligible.
Backlog processing can run tcp_reset(), which calls
tcp_done_with_error() to set sk->sk_err = ECONNRESET and then
tcp_done() to set sk->sk_shutdown = SHUTDOWN_MASK. The pre-existing
top-of-loop sk_err check already ran before the flush, so the
freshly-set error would be masked by the next-line sk_shutdown test
returning 0 (EOF). Re-check sk_err immediately before the sk_shutdown
test so a connection abort surfaces as -ECONNRESET rather than a clean
EOF.
Commit f508262ae9 ("tls: Preserve sk_err across recvmsg() when
data has been copied") gave the top-of-loop sk_err check a
has_copied split. The recheck applies the same handling: when the
caller has already copied bytes, sk_err is reported but preserved
so the error surfaces on the next call; otherwise sock_error()
consumes it so the error is reported exactly once.

Each record release via tls_strp_msg_done() triggered
tls_strp_check_rcv(), which called tls_rx_msg_ready() and
fired saved_data_ready(). During a multi-record receive, the
first N-1 wakeups are pure overhead: the caller is already
running and will pick up subsequent records on the next loop
iteration. The recvmsg and splice_read paths share this waste.
Suppress per-record notifications and emit a single one on
reader exit. tls_rx_rec_done() releases the current record
and parses the next without announcing; tls_strp_check_rcv()
gains a bool announce parameter so callers can request the
quiet form. tls_rx_reader_release() fires the deferred
announce on exit through tls_rx_msg_maybe_announce(), an
idempotent helper that calls saved_data_ready() only when a
record is parsed and has not yet been announced.
To keep the final notification idempotent against records that
the BH or the worker has already announced, tls_strparser gains
a msg_announced bit. tls_rx_msg_maybe_announce() sets the bit
when firing saved_data_ready(); the bit is cleared whenever
the parsed record is wiped, by tls_strp_msg_consume() on
consumption or by tls_strp_msg_load() when the lower socket
loses bytes from under the parse. A second call for the same
parsed record -- as when recvmsg() satisfies the request from
ctx->rx_list without touching the strparser -- becomes a
no-op.
With no remaining callers, tls_strp_msg_done() is removed.

tls_strp_msg_done() conflates releasing the current record with
checking for the next one via tls_strp_check_rcv(). A subsequent
patch needs to release a record without immediately triggering
that check, so the release step is separated into
tls_strp_msg_consume(). tls_strp_msg_done() is preserved as a
wrapper for existing callers.

Three receive paths -- recvmsg, read_sock, and splice_read --
each follow tls_rx_one_record() with the same tls_err_abort()
call. Consolidate the abort into tls_rx_one_record() so the
decrypt-and-abort sequence lives in one place.
A tls_check_pending_rekey() failure after successful
decryption no longer triggers tls_err_abort(). That path
fires only when skb_copy_bits() fails on a valid skb,
which is not a realistic scenario.
