net: qlcnic: validate unified ROM sections before loading
The unified ROM parser reads directory, product, and data-descriptor fields
from the firmware file. Existing validation forms table and data ends with
unchecked additions and multiplications. Malformed values can wrap before
they are compared with the firmware size. The parser also dereferences
typed pointers at firmware-controlled offsets.
Valid descriptor extents alone are insufficient for the consumers. The
loader reads a fixed-size bootloader regardless of its declared size, the
version parser assumes a 17-byte tail, and a partial final firmware word is
read as a full u64. A truncated image can therefore make the driver read
beyond the firmware allocation during validation or loading.
Replace the pointer-returning parser with bounded range helpers. Validate
table entry sizes, descriptor indices, section ranges, the fixed
bootloader load length, and the version tail before exposing any section.
Read all file fields with unaligned little-endian accessors and assemble a
partial final word from only the bytes that remain. Apply the same range
checks to the legacy image before reading its fixed fields.

bnx2x: fix double free in bnx2x_init_firmware() error path
bnx2x_init_firmware() frees bp->init_ops, bp->init_data and
bp->init_ops_offsets in its error path without setting them to NULL.
The cleanup function bnx2x_release_firmware() frees the same three
pointers unconditionally, so if init_firmware fails and
release_firmware is later called (e.g. from __bnx2x_remove or through
the function state machine), all three are freed a second time.
Set each pointer to NULL after kfree() in the error path so that the
subsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-op.

ipv6: avoid divide by zero in rt6_multipath_rebalance
rt6_multipath_rebalance() calculates the total eligible nexthop weight
in one pass and programs upper bounds in a second pass. Since
RTM_NEWROUTE is RTNL-free, a concurrent
ignore_routes_with_linkdown update can make the first pass return zero
while the second sees an eligible nexthop, causing
rt6_upper_bound_set() to divide by zero.

netdevsim: update queue NAPI association on queue reset
In netdevsim, receive queues (struct nsim_rq) embed their own struct
napi_struct. When queue reset is performed (e.g. via queue_reset
debugfs), nsim_queue_start() swaps in a newly allocated struct nsim_rq,
and nsim_queue_mem_free() later deletes and frees the old one.
However, nsim_queue_start() failed to update the queue-to-NAPI mapping
via netif_queue_set_napi(). As a result, dev->_rx[idx].napi continued to
point to the old NAPI struct. After the old queue was freed, a subsequent
queue dump via Netlink (NETDEV_CMD_QUEUE_GET) triggered a KASAN
slab-use-after-free read in nla_put_napi_id() when accessing
rxq->napi->napi_id.
Fix this by calling netif_queue_set_napi() in nsim_queue_start() to
associate the new NAPI with the RX queue, and clear the association
with netif_queue_set_napi(..., NULL) in nsim_del_napi() during teardown.

net: mctp: hold a reference to the route device in mctp_route_lookup()
mctp_route_lookup() uses rt->dev without holding a reference on it.
mctp_route_lookup_single() returns the route under RCU only, so the
route's device can be torn down concurrently: mctp_dev_put() drops the
last reference and synchronously kfree()s mdev->addrs. mctp_dev_saddr()
then reads rt->dev->addrs[0], giving a use-after-free reachable by an
unprivileged local AF_MCTP user on the receive/forwarding path (no
CAP_NET_RAW required):

This reintroduces the use-after-free class of CVE-2023-3439: the source

net: ipa: balance runtime PM reference on remove error
ipa_remove() takes a runtime PM reference before accessing IPA hardware
during teardown. If a concurrent modem start or stop keeps
ipa_modem_stop() busy across both attempts, the callback intentionally
returns without releasing the remaining resources because proceeding
with teardown could crash. That return also skips the matching
pm_runtime_put_noidle(), leaving the callback's usage-count reference
held.
Drop only this runtime PM reference before returning.
pm_runtime_put_noidle() does not request an idle transition, so the
hardware and resources retained on this exceptional path remain
untouched while the usage count stays balanced.
This issue was found by a static analysis checker and confirmed by
manual source review.

====================
forcedeth: two register-window bounds fixes
Two bounds fixes in forcedeth, both in the same shape: a loop that walks
the register window one step too far. They are independent of each other
and touch different functions.
1/2 nv_suspend() and nv_resume() save and restore the non-PCI config
space with i <= register_size/sizeof(u32). On a VER3 device that is
exactly the length of saved_config_space[], so the last iteration
reads and writes one element past the array, and on resume it
writel()s that element one dword past the length the driver mapped.
UBSAN catches it.
2/2 nv_tx_timeout() dumps the window in rows of eight dwords but only
bounds the row's starting offset, so the final row reads between 12
and 28 bytes past register_size, on every one of the three supported
window sizes.
Neither is a regression. Both are long standing, and 1/2 in particular
is not new to the list:

forcedeth: stop the tx_timeout register dump past the requested window
nv_tx_timeout() dumps the register window in rows of eight dwords:
for (i = 0; i <= np->register_size; i += 32) {
netdev_info(dev, "%3x: %08x ... %08x\n", i,
readl(base + i + 0), ..., readl(base + i + 28));
The loop bound only checks the row's starting offset, so the final row
reads a full 32 bytes from a position that is below the end of the window
but too close to it. base is mapped with exactly that length:
np->base = ioremap(addr, np->register_size);
so the tail of that row is read from beyond the length the driver asked
for. Per variant, the last iteration reads past register_size by:
NV_PCI_REGSZ_VER1 (0x270): row 0x260 reads to 0x27f, 16 bytes over
NV_PCI_REGSZ_VER2 (0x2d4): row 0x2c0 reads to 0x2df, 12 bytes over
NV_PCI_REGSZ_VER3 (0x604): row 0x600 reads to 0x61f, 28 bytes over
This happens on every supported device, not just one of them. Note that
it is not a consequence of the sizes being odd: with i <= register_size
the offending row is reached whatever the size, and a size that were a
multiple of 32 would overrun by a full row rather than by a remainder.
To be precise about the severity: the reads stay inside the BAR. Memory
BAR sizes are powers of two, the driver only accepts a region with
pci_resource_len() >= register_size (forcedeth.c:5757-5762), and the
next power of two at or above each register_size already covers the
offending row: 0x400 for 0x270 and 0x2d4, 0x800 for 0x604. ioremap()
also rounds the mapped length up to page granularity, so the reads land
inside the mapping the CPU has as well. What they leave is the window
the driver asked for, not the BAR and not the mapping. That is still a
driver reading registers it did not ask for, and it is trivial to
avoid, but nobody should expect a fault from it.
Changing <= to < is not enough: register_size is a length and every size
above is larger than its last row start, so i still reaches the offending
row. Check that the whole row fits instead.
The trade-off is that a partial trailing row is no longer dumped: 16 bytes
for VER1, 20 for VER2, 4 for VER3. That seemed preferable to reading
outside the requested window, and to open-coding a second, narrower dump
for the remainder in what is a debug-only path. Extending the dump to
cover the tail can be done on top if anyone misses those registers.
Only reachable with the debug_tx_timeout module parameter, which defaults
to false. It has not been observed at runtime: forcing a genuine TX
timeout on the reference machine is not something I can do safely, so this
rests on the arithmetic above and on a build test, not on a reproduction.
UBSAN does not catch it either, since these are MMIO reads rather than an
array access. It was found by reading the function while fixing the
saved_config_space off-by-one in nv_suspend() and nv_resume().
The dump was introduced with a fixed 0x400 bound while ioremap() mapped
only NV_PCI_REGSZ (0x270), so it read about 0x190 bytes too far from the
start. Commit

forcedeth: fix off-by-one when saving/restoring non-PCI config space
nv_suspend() and nv_resume() walk the non-PCI configuration space with for (i = 0; i <= np->register_size/sizeof(u32); i++) which runs one iteration too many. saved_config_space is declared as u32 saved_config_space[NV_PCI_REGSZ_MAX/4]; and NV_PCI_REGSZ_VER3 is equal to NV_PCI_REGSZ_MAX (0x604), so on a VER3 device register_size/sizeof(u32) is exactly the array length and the last iteration addresses one element past the end. The element it lands on is np->name_rx[0..3]: saved_config_space[] is followed immediately by char name_rx[IFNAMSIZ + 3], and char needs no padding. Nothing observable is corrupted by that, because nv_request_irq() rewrites name_rx with sprintf() before it is ever passed to request_irq(). The bug is the out-of-bounds access itself, which UBSAN reports and which CONFIG_UBSAN_TRAP=y turns into a trap that aborts the running kernel code, plus an MMIO read and, on resume, an MMIO writel() to base + 0x604, one dword past the range the driver mapped: np->base = ioremap(addr, np->register_size); VER1 and VER2 devices stay inside the array, but they too get the stray read and the stray write one dword past their own window. Caught by UBSAN on an Apple Macmini3,1 (MCP79) during a deep S3 cycle. The splat below is trimmed: the build path in the file name, the CPU and taint lines, the Workqueue line, the "?" hint frames, and the frames below device_suspend are all cut. The kernel was tainted, with an out-of-tree nouveau and CPU_OUT_OF_SPEC; forcedeth itself was the stock module. UBSAN: array-index-out-of-bounds in drivers/net/ethernet/nvidia/forcedeth.c:6225:25 index 385 is out of range for type 'u32 [385]' Call Trace: dump_stack_lvl+0x5d/0x80 ubsan_epilogue+0x5/0x2b __ubsan_handle_out_of_bounds.cold+0x54/0x59 __this_module+0xe398c/0xe9010 [forcedeth] pci_pm_suspend+0x80/0x170 dpm_run_callback+0x51/0x160 device_suspend+0x1a2/0x4a0 ... Both loops are hit. UBSAN reports each source location only once per module load (__ubsan_handle_out_of_bounds() calls suppress_report(), which does test_and_set_bit(REPORTED_BIT, ...) on the struct source_location), so the two splats land in the first S3 cycle after the module is loaded and later cycles are silent even though the access still runs off the end every time. In that first cycle line 6225 is reported from pci_pm_suspend and line 6240 from pci_pm_resume. The same off-by-one was fixed in nv_get_regs() by commit |

Merge branch 'net-mlx5-preserve-speed-and-state-across-vport-modify-commands'
Tariq Toukan says: ==================== net/mlx5: Preserve speed and state across vport modify commands The firmware vport modify command bundles both admin state and max tx speed in a single operation, which requires each side to preserve the other field when it only intends to change one. When modifying max tx speed, the driver already queries the current admin state and passes it back to avoid overwriting it. However, this query and the subsequent modify were not atomic, a state change between the two could cause the modify to overwrite the new state with a stale value. The fix holds esw->state_lock across the query-modify sequence. When support for setting max tx speed via the vport modify command was introduced, the existing admin state modify path was not updated to preserve the current speed. As a result, the firmware interprets the zero speed field as an intentional reset. The fix adds a speed query before the state modify and passes the result back in the command. To support that, mlx5_query_vport_max_tx_speed() had to be fixed first: it was returning zero whenever the vport was DOWN, which was correct for the query_port_speed verb but would defeat the purpose of querying before a state modify. The DOWN-to-zero logic is moved to the verb-layer caller so the function returns the raw firmware value. Patch #1 holds esw->state_lock across the state query and modify in the speed modify path Patch #2 moves the vport DOWN zero mapping to the verb-layer caller so the query returns the raw firmware value Patch #3 queries current max tx speed before modifying vport state to preserve it ==================== Link: https://patch.msgid.link/20260816065015.3280733-1-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net/mlx5: E-Switch, preserve max tx speed on vport state modification
When modifying vport state, the firmware interprets a zero in the max tx
speed field as an intentional reset, which can overwrite previously set
values. This patch attempts to fix this by querying the current max tx
speed from firmware before modifying the vport state and passing it back
in the modification command. If the query fails, fall back to the cached
agg_max_tx_speed value to avoid inadvertently resetting the speed.

net/mlx5: Move vport DOWN state check out of mlx5_query_vport_max_tx_speed()
mlx5_query_vport_max_tx_speed() was introduced to serve the
query_port_speed path, which uses max_tx_speed == 0 when port is down.
This is incorrect for callers that need the actual configured speed
regardless of vport state, such as modify-vport-state helpers
that must preserve the speed across state transitions.
Move this logic to the caller function in the verb flow and let
mlx5_query_vport_max_tx_speed() return the raw firmware value
unconditionally.

net: thunderbolt: Count delivered packets in rx_packets and rx_bytes
tbnet_poll() increments rx_packets once per received frame because that is
the NAPI work unit, and then adds the same number to stats.rx_packets. An
skb is handed to the stack only when the last frame of a packet arrives,
so once the MTU exceeds TBNET_MAX_PAYLOAD_SIZE the statistic reports
frames. tx_packets is bumped once per skb, so the two ends of a link
disagree: at MTU 65330 the receiver reports 16 times the packets its
sender sent.
rx_bytes has the matching problem: frames of a packet that is later
dropped mid-assembly are already accounted, so it does not correspond to
rx_packets as documented. Account for both where the packet is completed,
and leave the NAPI work counter alone.

ipv6: rpl: fix NULL dereference of idev in ipv6_rpl_srh_rcv()
ipv6_rpl_srh_rcv() dereferences idev from __in6_dev_get() without a NULL
check when reading idev->cnf.rpl_seg_enabled.
When the device's MTU drops below IPV6_MIN_MTU, addrconf_ifdown() clears
dev->ip6_ptr through RCU_INIT_POINTER(). A packet that passed the idev
check in ip6_rcv_core() can then reach ipv6_rpl_srh_rcv() with
dev->ip6_ptr already NULL.
Reproduced by flooding the receiving interface with ping6 traffic while

net/tcp-ao: fix use-after-free of current_key on reconnect to another peer
tcp_inbound_ao_hash() is called before bh_lock_sock_nested() is taken,
with only rcu_read_lock() held. On the fast path for established
sockets, if the rnext_keyid sent by the peer differs from
current_key->sndid, the key the peer asked for is looked up and stored
in current_key. The lookup is inside the RCU read side, but current_key
outlives it.
When the socket is disconnected and connect() is called again for
another peer, tcp_ao_connect_init() unlinks every key that does not
match the new peer and frees it with call_rcu(). If current_key points
at such a key, it is cleared to NULL.
The fast path reads sk_state only once on entry, so a softirq that got
into it while the socket was still established can update current_key
after that loop has already run. The update is inside the RCU read side,
so it comes before the call_rcu() callback, and once the callback frees
the key, current_key is left pointing at freed memory.
The next transmission picks that pointer up in tcp_get_current_key().
tcp_ao_transmit_skb() then reads the traffic key from the freed object,
which is the use-after-free.
Wait for one grace period before unlinking, and only if a key is going
to be removed. By the time tcp_connect() runs the socket is already in
TCP_SYN_SENT, and TCP_AO_ESTABLISHED does not contain TCPF_SYN_SENT, so
a softirq entering after the wait cannot reach the fast path, and the
ones already in it have finished. The existing NULL handling in the loop
is then enough.

net/sched: add get_fill_size callbacks for actions missing them
Several tc actions - act_police, act_bpf, act_pedit, act_ife, act_sample,
act_ct, act_ctinfo and act_tunnel_key among them - provide no
get_fill_size() callback, so tcf_action_fill_size() falls back to
tcf_action_shared_attrs_size() which does not account for the
action-specific netlink attributes emitted inside TCA_ACT_OPTIONS by
their dump functions.
When an RTM_NEWACTION request with NLM_F_ECHO (or an RTNLGRP_TC
listener) creates several actions, tcf_add_notify_msg() allocates the
echo skb from this underestimated size. When this happens, the act_api
code fails to add all of the fields to the netlink message and, thus,
fails to send it. Issue is that, when that happens, this failure doesn't
stop the action instances from being added. So any user watching these
events will be under the false impression that no actions were created at
all.
For example, act_pedit overruns with 32 actions of four munge keys each,
act_police with 32 policers once the optional rate/peakrate/result/avrate
attributes are present.
To fix this, add the missing get_fill_size callbacks returning the
worst-case size of each action's dump attributes, following the pattern
used by act_gact/act_skbedit/act_vlan. Also widen the TCA_GACT_TM
accounting in tcf_action_shared_attrs_size() to nla_total_size_64bit(),
since actions dump their tcf_t with nla_put_64bit(), which may be
preceded by an NLA_PAD attribute.
Note: We only provided fixes for the actions we reproduced this bug with
as of today. We can send a separate hardening patch for the remaining
actions to net-next later. The other pre-existing issues, pointed out by
Clashiko [1], will be fixed in upcoming patches.

net: advertise TCP MSS from the configured MTU, not the learned PMTU
The MSS a host puts in its SYN tells the peer how big a segment it may send us. Right now we can shrink it with a PMTU we learned on our own send path, which is the wrong direction entirely. On asymmetric paths this bites - think DSR load balancers, where the request side goes through a smaller-MTU overlay. We learn a small PMTU going out, then advertise a small MSS, and the peer stays capped for the whole connection even though its path back to us is wide. MSS only shows up in the SYN and never grows back. On symmetric paths we lose nothing by dropping it either: the peer runs its own PMTU discovery and usually already knows the real path MTU. So work out the advertised MSS from the configured route or device MTU and ignore the learned PMTU. Our send side is unchanged, still clamped by tcp_current_mss(). Add ip_dst_mtu_configured()/ip6_dst_mtu_configured() and use them from the two default_advmss() paths. Fixes: |

Error got introduced because functions are mistakenly declared in a

avoid any future mistake and drop the block entirely.
Change the module content slightly on CONFIG_OF=n. Previously match
tables were ignored. Now they appear in the resulting build. This is
considered trivial in size by most and is the common case:

254

Tangent: no, of_match_ptr() does not imply that the compiler can
optimize out match tables, because MODULE_DEVICE_TABLE(of, ...)
unconditionally puts the match tables in the binary. It is only meant
to avoid undefined declaration issues when match tables are hidden
behind a #ifdef, as was done before. We therefore drop the macro call.

This patch has some issues that are fixed with a followup patch. 6) xfrm: Fix skb double-free in xfrm_dev_direct_output() Stop freeing the skb unconditionally in xfrm_dev_direct_output(), letting local_out()'s result indicate when ownership has moved on. 7) xfrm: ah6: validate routing header segments_left Validate the segments_left/hdrlen invariant before rearranging the routing-header addresses, avoiding an OOB memmove on malformed HDRINCL packets. 8) xfrm: fix xfrm_state_construct() auth-trunc leak Detect an already-attached auth-trunc allocation by the pointer rather than inferring it from the algorithm id, so a prior attach isn't overwritten and lost. 9) xfrm: bound nat keepalive state collection Replace the per-state allocation in the NAT keepalive walk with a fixed-size batch that drains under BH-disabled locking and resumes from the cursor, bounding the worker's memory. * tag 'ipsec-2026-08-18' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec: xfrm: bound nat keepalive state collection Revert "esp: do not unref managed frag pages in esp_ssg_unref()" xfrm: fix xfrm_state_construct() auth-trunc leak xfrm: ah6: validate routing header segments_left xfrm: Fix skb double-free in xfrm_dev_direct_output() xfrm: avoid lock inversion in nat keepalive work xfrm: drop ESP-in-TCP packets with no ingress device xfrm: espintcp: fix UAF during close esp: do not unref managed frag pages in esp_ssg_unref() xfrm6: fix out-of-bounds write in xfrm6_input_addr() when secpath is full ==================== Link: https://patch.msgid.link/20260818092920.653034-1-steffen.klassert@secunet.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

ipv6: use RCU iterator to dump route exceptions
rt6_nh_dump_exceptions() uses hlist_for_each_entry() to iterate over
RCU-protected exception lists. The caller holds rcu_read_lock(), but does
not hold rt6_exception_lock, so rt6_insert_exception() can concurrently
add an entry with hlist_add_head_rcu().

net: ipa: fix stalled modem TX queue after runtime resume
ipa_start_xmit() unconditionally stops the TX queue before calling
pm_runtime_get(), relying on the wake scheduled by runtime resume
(ipa_modem_wake_queue_work()) to restart it once power is ACTIVE.
But that work is queued from within the runtime resume callback,
before the device's power state reaches RPM_ACTIVE, so it can run
while the device is still RPM_RESUMING. The wake is then consumed
too early: the transmit it restarts stops the queue again,
pm_runtime_get() returns -EINPROGRESS without arranging any future
wake (deferred_resume exists only for RPM_SUSPENDING), and after the
resume completes nothing is left to wake the queue. Transmit stalls
permanently: packets pile up in the qdisc behind the stopped queue,
the device runtime-suspends, and since the netdev registers no
ndo_tx_timeout the watchdog never fires. Observed on SM7635
(Fairphone 6) as the cellular data path going permanently deaf
within hours, RX included, since nothing resumes the suspended
endpoints.
Close the window by making the wake work wait for the resume to
complete (pm_runtime_get_sync()) before waking the queue. Every
queue stop is then guaranteed a later wake that happens while power
is ACTIVE; a transmit racing a new suspend/resume cycle re-schedules
the work. If the device could not be resumed, wake the queue anyway
so pending packets are dropped by the transmit path rather than
stranded.
The STARTED power flag used to narrow this window: a wake running
before the transmit path's stop suppressed that stop, but only once,
as the flag was cleared by the first stop it absorbed. Removing the
flag made a single transmit during an in-flight resume sufficient to
strand the queue, which is the form observed.
With an accelerated reproducer (autosuspend delay shortened to 5 ms,
~20 packets/s of TX), an unpatched kernel stalled three times in
230 s / 4380 packets; with this patch the same test ran 3601 s /
70298 packets without a stall.

net: bridge: Reject descending VLAN tunnel ranges
A pair of descending VLAN and tunnel IDs can pass the tunnel range span
check. The VLAN subtraction produces a negative int, which is converted
to unsigned when compared with the u32 tunnel ID subtraction. It can
therefore equal the wrapped tunnel ID delta.
The range loop then performs no iterations. Since the batched
notification handling added a post-loop error check, this leaves err
uninitialized and makes the request's return value unpredictable.
Reject descending VLAN ranges before comparing the spans. Valid
ascending and single-entry ranges remain unchanged, while malformed
descending ranges consistently return -EINVAL.
This issue was found by a static analysis checker and confirmed by
manual source review.

xsk: fix NULL pointer dereference in __xsk_rcv()
In the __xsk_rcv() multi-buffer path, xsk_buff_alloc() is called in a
loop without checking its return value. xsk_buff_can_alloc() only
counts fill queue entries without validating their addresses, so it
can succeed while xsk_buff_alloc() rejects all remaining entries and
returns NULL.
Oops: general protection fault, probably for non-canonical address
0xdffffc0000000000
KASAN: null-ptr-deref in range
[0x0000000000000000-0x0000000000000007]
RIP: 0010:__xsk_rcv+0x426/0xc20 (net/xdp/xsk.c:350)

do_xdp_generic+0x92f/0xe70
__netif_receive_skb_core.constprop.0+0xf7e/0x2b30
Fix this with a two-stage transaction. First allocate and stage all
buffers required for the packet, recycling all staged buffers with
xsk_buff_free() if any allocation fails. Only after this stage
succeeds, copy the data, reserve the RX descriptors, and release the
buffers in an error-free loop.

Pull networking updates from Jakub Kicinski:
"One of the 'small improvements all over the place' releases for us.
It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.
Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.
We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.
The sad truth is that our APIs (especially for rare events like PCIe
errors, timeouts etc) have always been racy, and now LLMs don't let us
ignore that. I expect our direction for the next release will be to
tweak the reviews a little bit more, but start shifting focus to
letting the LLMs take care of the busy work - managing patchwork,
automating common process complaints, editing commit messages, and
maybe applying patches which already got "reviewed-by" tags from
people we trust...
Core & protocols:
- A few steps lowering rtnl_lock dependence:
- per-netns netdev unregistration for select SW drivers (e.g.

__arena and __arena__nullable suffixes (Tejun Heo, Puranjay Mohan,
Kumar Kartikeya Dwivedi, Ihor Solodrai)
- Signed BPF program loader rework to accommodate both BPF and
security community needs where the kernel runs the signature
verification at BPF_PROG_LOAD time before the LSM admission hook
(Daniel Borkmann)
- Add a set of ksock kfuncs which let BPF LSM and syscall programs
create, connect and send on UDP sockets in order to emit telemetry
data (Mahe Tardy)

loops no longer pay a kfunc call on every iteration (Puranjay
Mohan)
- Add an arena-based bitmap data structure to libarena along with
serial and parallel selftests (Emil Tsalapatis)
- Teach resolve_btfids to discover kfuncs from the kernel's BTF ID
sets and to emit kfunc BTF decl tags, reducing the kernel build's
dependency on pahole features (Ihor Solodrai)
- Add BPF_F_ADJ_ROOM_DECAP_* flags to bpf_skb_adjust_room() so that
tunnel decapsulation can update the GSO and encapsulation state of
the skb (Nick Hudson)

accounting on 32-bit position wrap (Israel Téllez García)
- Add memory usage accounting for arena maps and fix an mmap_lock
deadlock on arena lock failure (Jiayuan Chen)

(Jiri Olsa)
- Support BPF_F_EGRESS in bpf_redirect_peer() to emit the skb in the
egress direction of the target's peer device (Jordan Rife)

modules, can declare kfuncs safe to call under bpf_spin_lock
instead of relying on the verifier's hard-coded allowlist (Kaitao
Cheng)
- Introduce global percpu data for BPF programs with libbpf probing
and bpftool skeleton support, and stop exposing uninitialized
kernel heap memory when copying per-CPU map values (Leon Hwang)

- Invalidate RCU pointers only after the final spin unlock and
account for preempt and IRQ disabled regions as overlapping RCU
protection (Ning Ding)
- Support mixing bpf2bpf calls and tail calls on RV64, add signed
operations and 32-bit atomics to the RV32 JIT, and add timed
may_goto support (Pu Lehui, Kuan-Wei Chiu, Feng Jiang)
- Fix a use-after-free on mm_struct in bpf_find_vma() for foreign
tasks and an mmap_lock leak in the irq_work path (Sanghyun Park)
- Populate mmap-able BPF array map memory lazily which makes mmap()
O(1) instead of proportional to the map size (Song Liu)
- Introduce a jit_required flag and reject programs with inlined
helpers when no JIT is available, where the interpreter would
otherwise jump into an invalid address (Tiezhu Yang)
- Fix the x86 JIT per-CPU address resolution into an extended
register where the REX prefix dropped the high destination register
bit (Vineet Gupta)
- Reject MEM_ALLOC BTF accesses past object bounds, arena frees below
the arena base, and mixed arena and ordinary atomic paths (Yiyang
Chen)
- Fix the trampoline handling of 128-bit arguments and of return
values larger than 8 bytes (Yonghong Song)
- Ensure that any fault prone load is rewritten with exception table
handling, and fix the arena load-acquire and atomic fetch handling
in the x86, arm64, riscv and s390 JITs (Daniel Borkmann)

Pull selinux updates from Paul Moore: - Convert a __get_free_page() call into a kmalloc() call We had some very old code that called out to __get_free_page() for allocating a pathname. There is no reason this couldn't be done with a call to kmalloc() so we've done the conversion and now there is one less __get_free_page() caller in the kernel. - Limit the number of retired/unknown DCCP netlink messages While DCCP is gone from the kernel, there are still userspace tools which try to talk to the kernel about DCCP sockets which were generating SELinux related log noise (unrecognized netlink message). This pull request both limits the log messages to just the first instance and also explains to the user that DCCP support has been removed. - Convert the SELinux strlcat() calls to seq_buf_XXX() calls As part of the effort to drop the strlcat() API from the kernel, the SELinux/IMA code was converted over to using seq_buf_XXX() calls. - Only calculate the SELinux IMA configuration string length once Previously each call to generate a SELinux configuration string for IMA would have to calculate the length of the string. While the contents of the string will likely change over the lifetime of the system, the length of the string will not. Calculate the string length once at boot and reuse the length value throughout the lifetime of the system. - Further validation of the SELinux policy at policy load time Perform additional sanity checks on the policy constraints and types. - Proper cleanup and error handling for selinuxfs init failures We were not properly cleaning up some state in the case where selinuxfs fails to initialize properly. It's somewhat of an academic exercise as a failure to initialize selinuxfs will cause the system to fail on boot, but it's arguably better to make sure we do things the proper way. - Various code cleanups Convert integer flags to boolean types and drop an uncessary goto from the SELinux code. * tag 'selinux-pr-20260814' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: validate constraint expression attr and op at load time selinux: compute the IMA configuration settings string length once at boot selinux: replace strlcat() with seq_buf in selinux_ima_collect_state() selinux: suppress warning flood for retired DCCP netlink messages selinux: tighten type validation during policy load selinux: drop unnecessary goto and label from avc_alloc_node() selinux: convert int flags to bool flags in ss/services.c selinux: clean up selinuxfs resources on init failure selinux: hooks: use kmalloc() to allocate path buffer |

Pull ring-buffer updates from Steven Rostedt: - Remove unneeded semicolon A macro ended with a semicolon that wasn't needed. - Fix freeing cpu_buffer extra subbuffer with order greater than zero When the cpu_buffer was being freed, its "free" page, was using free_page() to free it when it could be more than one page. - Hold the cpu_buffer lock when resizing the subbuffer The freeing of the "free" page of the cpu_buffer was done without locking. The order of the data was being saved and then the "free" page was set to NULL. But there is a race that the "free" page could have been updated between those two operations. Add locking around it to prevent the race. - Save the order of the data along with the data in the free page The cpu_buffer would store just the data portion of the subbuffer page in its descriptor. But it did not store the order of the data pages. The order was being saved in the global buffer descriptor. But this leads to races. Have the cpu_buffer save the subbuf data along with its metadata (which includes the order of the page) to make sure when it frees it, it frees the correct order along with it. - Remove the subbuf_size and use the order directly when needed Having a size field for the size of the subbufer along with its order allowed for races to have them get out of sync. Remove the subbuf_size and use the order from the subbuf meta data directly under locks. Use the subbuf_order for other calculations in the ring buffer. - Remove the useless "cpus" field of trace_buffer The code has been restructured and the "cpus" field is no longer used. Remove it. - Remove the "mapped" field of the ring buffer and use a helper function instead. The "mapped" field has become a bit overused and made the code come complex in using a counter for what is denoted as being mapped or not. There are other fields that are set when the ring buffer is considered mapped.

Previously, a failure after directory creation wouldn't clean up eventfs_inode because the error path didn't call eventfs_remove_dir(). This eliminates the need to clean up the eventfs directories if event_define_fields() fails. - Add warning for out of bounds pos in __eventfs_iterate() Sashiko complains about the ctx->pos causing issues if it is less than 2 or greater than MAX_INT in __eventfs_iterate(). The thing is, the logic prevents that from happening.

Merge tag 'trace-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Expose btf_ids to trace events
In order to allow BPF programs to attach to system call trace events
(which are actually pseudo trace events built on top of raw_syscall
events), expose the BTF ID of the events. This will allow BPF
programs better precision in attaching to events.
- Use "u64" to assign to hist_field->type
Instead of using kstrdup("u64", GFP_KERNEL) to assign the
hist_field->type, just point it to "u64" instead. The
hist_field->type is freed via kfree_const().
- Replace kmalloc()/strcpy() with kstrdup() for trace_printk
Instead of having two calls to copy the module format string, just
use kstrdup().
- Use __free() in trace event histograms and triggres where possible
- Use seq_buf in trace event code instead of strcat()
Instead of calculating the size of the buffer to use and filling it
with strcat(), use the seq_buf infrastructure that takes care of
making sure not to overflow the string size.
- Reject invalid preemptirq_delay_test CPU affinity
The preempt_delay_test module can take an invalid CPU affinity mask
and create confusing output. Simply have the module reject invalid
affinity masks.
- Prevent division by zero in ftrace_ops sample module code
If the ftrace_ops sample module code receives the module parameter
nr_function_calls set to zero, it can cause a division by zero error.
- Warn when an event dereferences a parameter in TP_printk()
On boot up and module load, the trace event TP_printk() is scanned
for possible bugs. As the TP_printk() code is executed when the user
reads the "trace" file and processes the data written when the
trace_event executed, the data it reads can be literally days old.
The scan currently checks for dereferencing printk formats like
"%pI6". But it does not check if the parameters themselves have a
dereference like:
TP_printk("offset %08x: value %08x",
(u32)(__entry->addr - __entry->edma->membase), __entry->value)
__entry represents the pointer to the event on the ring buffer. The
__entry->edma->membase is dereferencing a pointer on the ring buffer
to find membase, but the __entry->edma may no longer be a valid
pointer.
Warn on this case too.
- Replace some strcpy() with strscpy()
- Clean up mmiotrace events to use assign_type() macro
The assign_type() macro makes sure the event type is indeed the type
that is being parsed. The mmiotrace trace was written before that
macro was created so it just simply typecasted the pointer.
Replace the typecasting with the macro.
- Have the ENUM processing to numbers only process what is added
The code that converts ENUMs to their numbers in the trace events
scanned all events to do the processing. This was true when a module
was loaded too. That is, instead of processing just the events for
the module, it processed *all* events. Even the builtin ones that
were processed at boot up.
Add a check for the event->module matching mod if it is a module
before processing it.

Merge tag 'ftrace-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ftrace updates from Steven Rostedt: - Deprecrate ftrace_enabled in disabling ftrace The file /proc/sys/kernel/ftrace_enabled was created when ftrace was first introduced back in 2008. It was to be a "kill switch" if something was to go wrong. It was also used as a way to turn off function tracing for the latency tracers that would have it on by default. But in 2013 (Linux 3.10) the option "function-trace" was introduced to disable function tracing for the latency tracers as the "ftrace_enabled" file was considered too big of a hammer and caused too many side effects. When live kernel patching came along, disabling ftrace via the ftrace_enabled file would put the system into an unstable state if a live kernel patch was installed. This created the need to mark some function hooks as "PERMANENT". Now there's a need for BPF usage marked as PERMANENT for the same reasons. The file "ftrace_enabled" usage is no longer viable. It doesn't do what it says it does and there is no reason to use it. Make writing '0' to it a nop and print a message saying its usage is deprecated. The return value of writing '0' is -EOPNOTSUPP so that user space will error on that write (hopefully to inform any developer that it no longer works). Eventually the file should be removed completely, but for now just making it not do anything is the path forward to that. - Update the livepatch tests to handle ftrace_enabled being disabled Because in the past, livepatch was broken by ftrace_enabled being turned off, there's a test case that checks to make sure it still doesn't break. But having the write of '0' return an error caused that test to break. Updated the test to handle the new change. * tag 'ftrace-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: selftests/livepatch: update test-ftrace.sh for deprecated ftrace_enabled ftrace: deprecate disabling via ftrace_enabled sysctl |

Pull Real-time Verifier updates from Steven Rostedt: - Switch LTL and DOT parsers to Lark in code generation tool The rvgen code generation tool originally parsed DOT files and LTL specifications using custom string parsing and Ply, which is no longer maintained. The DOT parser was fragile and prone to failure on minor format variations. Both LTL and DOT parsers have been rewritten to use the Lark parsing library. - Simplify Hybrid Automata clock variables The clock variables in hybrid automata monitors now use a single representation of the elapsed time since the clock was reset, rather than converting between invariant and guard representations. This allows simpler code generation for the newly refactored parser. - Generate cleanup hook for per-obj monitor The code generation scripts now adds a cleanup function to per-obj monitors for the user to wire to the appropriate event (e.g. sched_process_exit for tasks). - Reduce read_lock scope during per-task cleanup Take the tasklist_lock only when necessary, that is when iterating over for_each_process_thread(). - Simplify task monitor slot management Only rely on the slot array for per-task slot management to avoid inconsistency with the unused counter. - Improve rvgen code robustness and templates Use pathlib in rvgen and improve kernel path discovery. Also improve consistency across templates when generating code (e.g. author placeholder and monitor struct name). - Update rtapp sleep monitor Simplify the sleep monitor by excluding kernel threads and updating the nanosleep check to focus only on CLOCK_REALTIME. Also switch to use the sched_exit tracepoint to run in the context of the offending (wakee) task. - Add wakeup monitor Add the new rtapp/wakeup monitor to detect when lower-priority tasks wake up higher-priority ones, complementing the existing sleep monitor by running in the waker context and capturing its stack trace. - Fix tools/rv exit status on failure Ensure the rv tool returns a failure exit code when a monitor fails to start because it was already running. - Add automated selftests for tools/rv and rvgen Introduced automated bash selftests to validate rv monitor listing and execution under different configurations. Added tests for the rvgen code generator, validating generated files against expected output (golden). Tests are reachable via make check. - Add KUnit test coverage for verification monitors Added comprehensive KUnit tests to validate the functionality of deterministic, hybrid, and LTL monitors by emulating event sequences and timing in a mock environment without affecting the running kernel while expecting mock reactions to fire. Ensure real RV monitors cannot run during KUnit tests to avoid state corruption. - Mock current in rv monitors Mock the call to current in rv monitors when the KUnit tests are built to allow them to run the test on dummy tasks. No overhead is expected when KUnit tests aren't running. - Introduce rvgen kunit subcommand Added a new 'kunit' subcommand to rvgen to automatically patch an already generated monitor with KUnit integration templates by parsing its event handlers and creating the required mock structures and initializations. - Refine kernel verification selftests Added new selftests for the deadline and stall monitors and rearranged the existing wwnr_printk test to resolve flakiness. Additionally, fixed an issue in the selftests framework where negative assertion failures were not correctly propagated due to shell rules. - Fix 32-bit build of nomiss KUnit test A previous commit introduced a division between an u64 and a constant value and that doesn't build on 32-bit systems. Use div_u64() instead. - Document changes in sleep monitor The sleep monitor introduced some changes in the past like allowing epoll_wait() as a valid sleep and a task going to runnable before scheduling as a valid wakeup.

Merge tag 'driver-core-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core
Pull driver core updates from Danilo Krummrich:
"container_of:
- Apply typeof_member(), remove the local __mptr variable to
eliminate variable shadowing warnings on nested container_of()
calls, and remove unnecessary parentheses
core:
- Add driver name to probe debug print for initcall_debug
- Avoid repeatedly printing the same 'Fixed dependency cycle' log
- Unwind device_add() on attribute creation failure in
attribute_container_add_class_device()
- Remove statistics group if encryption group creation fails in
transport_add_class_device()
debugfs:
- Fix lockdown check for mmap_prepare()
- Warn if file creation failed due to uninitialized debugfs
device property:
- Implement fw_devlink support for software nodes by adding
software_node_add_links(), which creates fwnode links from
DEV_PROP_REF properties to enable automatic probe ordering. Add
kunit-managed fwnode helpers and test coverage
- Fix infinite loop in fwnode_for_each_child_node() when the
secondary fwnode has more than one child. Add test cases
- Fix out-of-bounds access in software_node_get_reference_args() when
called with index -1 (UINT_MAX)
- Refactor to use RAII approach with __free()
- Add Bartosz Golaszewski as software node reviewer
firmware loader:
- Fix race where a sysfs fallback request can complete before being
queued as pending, leading to a use-after-free on the next fallback
request
- Reject 0-size built-in firmware and fail the build on empty
firmware files in CONFIG_EXTRA_FIRMWARE
kobject:
- Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros
and allow the constification of kobject attributes, enabling them
to reside in read-only memory
platform:
- Provide platform_device_set_of_node(), platform_device_set_fwnode(),
and platform_device_set_of_node_from_dev() helpers that encapsulate
firmware node reference counting for dynamically allocated platform
devices
Convert all in-tree users that manually assigned dev.of_node or
dev.fwnode, fixing a pre-existing refcount bug in powermac. Switch
to counting references of all firmware node types, not only OF
nodes
- Unify the release path for dynamically allocated platform devices
by removing platform_device_release_full(). Amend the fwnode setter
API contract to warn if a primary software node is overwritten. Add
KUnit tests for correct software node removal on device
unregistration
Rust:
- Auxiliary:
- Add registration_data_with() closure-based API for invariant
ForLt types
- Debugfs:
- Migrate BinaryWriter and BinaryReaderMut trait requirements
from kernel::transmute traits to zerocopy traits
- Device:
- Add BoundInternal device context and InternalBoundContext trait
for bus abstractions that need internal access to a bound
device.
- Make the lifetime on Core and CoreInternal invariant to prevent
coercion to shorter lifetimes
- Devres:
- Fix race between concurrent revokers where the losing revoker
could return before the winning revoker finished dropping the
inner data, causing use-after-free.
- Ensure revocation is complete before the device finishes
unbinding by making the synchronization bidirectional.
- Add DevresLt<F: ForLt>, a wrapper around Devres that shortens
'static back to the caller's borrow scope. Implement ForLt and
CovariantForLt for Bar, IoMem, and ExclusiveIoMem
- Driver:
- Switch from index-based to pointer-based device ID info lookup,
storing static references in driver_data. Centralize device ID
handling in device_id.rs, removing the open-coded ACPI/OF
matching logic and duplicate ID table from driver.rs
- I/O:
- Make I/O regions typed (with a dynamically-sized Region type
for the existing untyped case), create view types representing
subregions of a mapped I/O region, and add io_project!() for
safely creating subviews.
- Split Io into a base trait (IoBase) and an extension trait (Io)
with a blanket implementation, preventing implementers from
overriding provided methods that unsafe code relies on.
- Add a SysMem backend for shared system memory with volatile
access, and make Coherent implement Io via an I/O view type.
Add IoSysMap as sum type of Mmio and SysMem. Add copying
methods (memcpy_{from,to}io()) and read_val()/write_val() for
typed access.
- Replace dma_read!()/dma_write!() with io_read!()/io_write!()
for primitives and copying methods for aggregates; drop the old
macros. Convert nova-core to use I/O projection.
- Fix internal shortcut rule dispatch in the register!() macro,
remove unused rule arguments, and use path fragments for alias
destinations
- IRQ:
- Make irq::Registration compatible with lifetime-bound drivers
by removing the 'static bound on Handler/ThreadedHandler and
replacing Devres<RegistrationInner> with direct
request_irq()/free_irq() calls. Handlers can now directly own
lifetime-bound device resources
- PCI:
- Convert IrqVectorRegistration to a lifetime-annotated owning
type, giving drivers explicit control over the allocation
lifetime. IrqVector embeds a resolved IrqRequest, making the
conversion infallible. Remove the redundant
request_irq()/request_threaded_irq() wrappers from pci::Device.
- Add pci_irq_type() C helper and expose it via irq_type() on
IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX,
PCI_IRQ_MSI, or PCI_IRQ_INTX.
- Mark pci::Device refcount methods inline
- Serdev:
- Add Rust abstractions for the serial device bus, including
serdev::Driver trait, serdev::Device wrapping struct
serdev_device, and serdev::Adapter implementing
RegistrationOps. Includes a sample driver. Markus Probst takes
over as serdev maintainer for both C and Rust code
- Misc:
- Split ForLt into a base trait (providing the Of<'a> GAT) and an
unsafe CovariantForLt subtrait guaranteeing covariance,
enabling invariant types (e.g. those containing Mutex<&'bound T>)
to participate in the ForLt abstraction.
- Fix Coherent read past EOF returning -ERANGE instead of zero.
- Fix firmware example UB by avoiding null-pointer ARef
misc:
- Avoid iattr allocation in kernfs listxattr by using
kernfs_iattrs_noalloc().
- Unregister SoC bus on early device registration failure.
- Remove unused DMA_FENCE_TRACE Kconfig symbol.
- Fix /sys/module path in comment.
- Refactor ISA bus init to remove nested blocks.
- Remove redundant nodemask clears in numa_init().
- Add kernel-doc for fwnode_operations and sys_soc.h, mark
internal property data as private for kernel-doc, and add
property.h/fwnode.h to driver-api infrastructure docs.
- Add MAINTAINERS entry for sys_soc.h"
