NAT helpers such as nf_nat_h323 store a raw pointer to module text in
exp->expectfn (e.g. ip_nat_q931_expect). nf_ct_helper_expectfn_unregister()
only unlinks the callback descriptor and never walks the expectation table,
so an expectation pending at module removal survives with a dangling
exp->expectfn into freed module text.
When the expected connection arrives, init_conntrack() invokes
exp->expectfn(), now a stale pointer into the unloaded module. Reproduced
on a KASAN build by loading the H.323 helpers, creating a Q.931
expectation, unloading nf_nat_h323, then connecting to the expected port:
Oops: int3: 0000 [#1] SMP KASAN NOPTI

__sys_connect (net/socket.c:2167)
Modules linked in: nf_conntrack_h323 [last unloaded: nf_nat_h323]
Reaching the dangling state requires CAP_SYS_MODULE in the initial user
namespace to remove a NAT helper that still has live expectations, so this
is a robustness fix; leaving an expectation pointing at freed text is wrong
regardless.
Add nf_ct_helper_expectfn_destroy(), which walks the expectation table and
drops every expectation whose ->expectfn matches the descriptor being torn
down. Call it from each NAT helper's exit path after the existing RCU grace
period, so no expectation outlives the code it points at and no extra
synchronize_rcu() is introduced. With the fix, the same reproducer runs to
completion without the Oops.

As we do for CRTC color mgmt properties, use color_mgmt_changed flag to
track any value changes in the color pipeline of a given plane, so that
drivers can update color blocks as soon as plane color pipeline or
individual colorop values change. Since we're here, only announce and
track changes to plane COLOR_PIPELINE prop if its value is actually
changing.

skb_is_err_queue() treats PACKET_OUTGOING as the sole marker for an skb
from sk_error_queue. That assumption is not true for AF_PACKET sockets:
outgoing packet taps are also delivered to packet sockets with
skb->pkt_type == PACKET_OUTGOING, but their skb->cb is owned by AF_PACKET
instead of struct sock_exterr_skb.
If such an skb is received with timestamping enabled, the generic
timestamp cmsg path can read AF_PACKET control-buffer state as
sock_exterr_skb::opt_stats. With SO_RXQ_OVFL enabled, the packet drop
counter overlaps opt_stats. An odd drop count makes the path emit
SCM_TIMESTAMPING_OPT_STATS with skb->len and skb->data. For non-linear
skbs this copies past the linear head and can trigger hardened usercopy or
disclose adjacent heap contents.
Keep skb_is_err_queue() local to net/socket.c, but make it verify that
the PACKET_OUTGOING marker is paired with the sock_rmem_free destructor
installed by sock_queue_err_skb(). AF_PACKET receive skbs use normal
receive ownership and no longer pass as error-queue skbs, while legitimate
sk_error_queue entries keep the PACKET_OUTGOING marker and sock_rmem_free
ownership.

Pull runtime verifier fixes from Steven Rostedt:
- Fix reset ordering on per-task destruction
Reset the task before dropping the slot instead of after, which was
causing out-of-bound memory accesses.
- Fix HA monitor synchronization and cleanup
Ensure synchronous cleanup for HA monitors by running timer callbacks
in RCU read-side critical sections and using synchronize_rcu() during
destruction.
- Avoid armed timers after tasks exit
Add automatic cleanup for per-task HA monitors to prevent timers from
firing after task exit.
- Fix memory ordering for DA/HA monitors
Fix race conditions during monitor start by using release-acquire
semantics for the monitoring flag.
- Fix initialization for DA/HA monitors
Ensure monitors are not initialized relying on potentially corrupted
state like the monitoring flag, that is not reset by all monitors
type and may have an unknown state in monitors reusing the storage
(per-task).
- Fix memory safety in per-task and per-object monitors
Prevent use-after-free and out-of-bounds access by synchronizing with
in-flight tracepoint probes using tracepoint_synchronize_unregister()
before freeing monitor storage or releasing task slots.
- Adjust monitors for preemptible tracepoints
Fix monitors that relied on tracepoints disabling preemption.
Explicitly disable task migration when per-CPU monitors handle events
to avoid accessing the wrong state and update the opid monitor logic.
- Fix incorrect __user specifier usage
Remove __user from a non-pointer variable in the extract_params()
helper.
- Fix bugs in the rv tool
Ensure strings are NUL-terminated, fix substring matching in monitor
searches, and improve cleanup and exit status handling.
- Fix several bugs in rvgen
Fix LTL literal stringification, subparsers' options handling, and
suffix stripping in dot2k.

If IB_MR_REREG_ACCESS changes from RO to RW then the umem has to be
re-evaluated to ensure it is properly pinned as RW. Since the umem is
hidden inside each driver's mr struct add a ib_umem_check_rereg() function
that each driver has to call before processing IB_MR_REREG_ACCESS.
mlx4 has to retain its duplicate ib_access_writable check because it
implements IB_MR_REREG_ACCESS | IB_MR_REREG_TRANS by changing both items
in place sequentially while the MR is live, so it will continue to not
support this combination.

Pull tracing fix from Steven Rostedt:
- Fix CFI violation in probestub function
The probestub is a function to allow tprobes to hook to a tracepoint
to gain access to its parameters.
The function itself is only referenced by the tracepoint structure
which lives in the __tracepoint section. objtool explicitly ignores
that section and when processing functions in the kernel, if it
detects one that has no references it will seal it to have its ENDBR
stripped on boot up.
This means the probstub function will have its ENDBR stripped and if
a tprobe is attached to it with IBT enabled, it will go *boom*.

tcf_pedit_act() computes the COW range for skb_ensure_writable()
once before the key loop using tcfp_off_max_hint, but the hint does
not account for the runtime header offset added by typed keys. This
can leave part of the write region un-COW'd.
Fix by moving skb_ensure_writable() inside the per-key loop where
the actual write offset is known, and add overflow checking on the
offset arithmetic. For negative offsets (e.g. Ethernet header edits
at ingress), use skb_cow() to COW the headroom instead. Guard
offset_valid() against INT_MIN, where negation is undefined.

The probestub is a function to allow tprobes to hook to a tracepoint to
gain access to its parameters. The function itself is only referenced by
the tracepoint structure which lives in the __tracepoint section. objtool
explicitly ignores that section and when processing functions in the
kernel, if it detects one that has no references it will seal it to have
its ENDBR stripped on boot up.
This means when a tprobe is attached to the sched_wakeup tracepoint, when it
is triggered it will call __probestub_sched_wakeup and due to the missing
ENDBR on a CFI-enabled machine it will take a #CP exception.
Fix this by adding CFI_NOSEAL annotation to probestub declaration.

net/bluetooth/l2cap_core.c:l2cap_sig_channel() accepts BR/EDR
signaling packets up to the channel MTU and dispatches each command
without enforcing the signaling MTU (MTUsig). A Bluetooth BR/EDR peer
within radio range can send a fixed-channel CID 0x0001 packet that is
larger than MTUsig and contains many L2CAP_ECHO_REQ commands before
pairing. In a real-radio stock-kernel run, one 681-byte signaling
packet containing 168 zero-length ECHO_REQ commands made the target
transmit 168 ECHO_RSP frames over about 220 ms.
Impact: a Bluetooth BR/EDR peer within radio range, before pairing, can
force 168 ECHO_RSP frames from one 681-byte fixed-channel signaling
packet containing packed ECHO_REQ commands.
Define Linux's BR/EDR signaling MTU as the spec minimum of 48 bytes and
reject any larger signaling packet with one L2CAP_COMMAND_REJECT_RSP
carrying L2CAP_REJ_MTU_EXCEEDED before any command is dispatched.
The Bluetooth Core spec wording for MTUExceeded says the reject
identifier shall match the first request command in the packet, and
that packets containing only responses shall be silently discarded.
Linux intentionally deviates from that prescription: silently
discarding desynchronizes the peer because the remote stack never
learns its responses were dropped, and locating the first request
command requires walking command headers past MTUsig, i.e. processing
bytes from a packet we have already decided is too large to process.
We therefore always emit one reject and use the identifier from the
first command header, a single fixed-offset byte read.
The unrestricted BR/EDR signaling parser and ECHO_REQ response path both
trace to the initial git import; no later introducing commit is
available for a Fixes tag.

Tracepoint handlers are fully preemptible after a46023d5616 ("tracing:
Guard __DECLARE_TRACE() use of __DO_TRACE_CALL() with SRCU-fast"). When
a per-CPU monitor handles an event, it retrieves the monitor state using
a per-CPU pointer. If the event itself doesn't disable preemption, the
task can migrate to a different CPU and we risk updating the wrong
monitor.
Mitigate this by explicitly disabling task migration before acquiring
the monitor pointer. This cannot guarantee the monitor runs on the
correct CPU but reduces the race condition window and prevents warnings.

HA monitors may start timers, all cleanup functions currently stop the
timers asynchronously to avoid sleeping in the wrong context.
Nothing makes sure running callbacks terminate on cleanup.
Run the entire HA timer callback in an RCU read-side critical section,
this way we can simply synchronize_rcu() with any pending timer and are
sure any cleanup using kfree_rcu() runs after callbacks terminated.
Additionally make sure any unlikely callback running late won't run any
code if the monitor is marked as disabled or if destruction started.
Use memory barriers to serialise with racing resets.

Hybrid automata monitors may start timers, depending on the model, these
may remain active on an exiting task and cause false positives or even
access freed memory.
Add an enable/disable hook in the HA code, currently only populated by
the per-task handler for registration and deregistration.
This hooks to the sched_process_exit event and ensures the timer is
stopped for every exiting task. The handler is enabled automatically but
may be disabled, for instance if the monitor uses the event for another
purpose (but should still manually ensure timers are stopped).

Hybrid Automata monitors hook into the DA implementation when doing
da_monitor_reset(). This function is called both on initialisation and
teardown, HA monitors try to cancel a timer only when it's initialised
relying on the da_mon->monitoring flag. This flag could however be
corrupted during initialisation. This happens for instance on per-task
monitors that share the same storage with different type of monitors
like LTL or in case of races during a previous teardown.
Stop relying on the monitoring flag during initialisation, assume that
can have any value, so use a separate da_reset_state() skiping timer
cancellation.
New monitors (e.g. new tasks) are always zero-initialised so it is safe
to rely on the monitoring flag for those.

da_monitor_start() set monitoring=1 before calling da_monitor_init_hook(),
may racing with the sched_switch handler:

ha_start_timer_ns(...);
/* hrtimer->base == NULL, crash */
da_monitor_init_hook(da_mon);

Fix the ordering and pair with release/acquire semantics:
da_monitor_init_hook(da_mon);
smp_store_release(&da_mon->monitoring, 1); /* da_monitor_start() */
return smp_load_acquire(&da_mon->monitoring); /* da_monitoring() */
On ARM64 a plain STR + LDR does not form a release-acquire pair, so
the load can observe monitoring=1 while hrtimer->base is still NULL.
The plain accesses are also data races under KCSAN.
Use WRITE_ONCE for the monitoring=0 store in da_monitor_reset() to
cover the reset path.

Per-task monitors use task_mon_slot to determine which slot in the array
to use for the monitor. During destruction, this slot is returned but
this is done before resetting the monitor. As a result, the monitor's
reset is in fact resetting a slot that is outside of the array
(RV_PER_TASK_MONITOR_INIT).
Release the slot only after the reset to avoid out-of-bound memory
access.

struct rseq_ids ids = {
.cpu_id = task_cpu(t),
.mm_cid = task_mm_cid(t),
.node_id = cpu_to_node(ids.cpu_id),
};
According to the C standard, the evaluation order of expressions in an
initializer list is indeterminately sequenced. The compiler (Clang, in
this KMSAN build) evaluates `cpu_to_node(ids.cpu_id)` *before*
`ids.cpu_id` is initialized with `task_cpu(t)`.
This is fixed by moving the assignment of ids.node_id outside the
structure initialization.

When NEWTFILTER and DELFILTER are run concurrently it is possible to create a
race with an associated action.
Let's illustrate with CPU0 running NEWTFILTER and CPU1 running DELFILTER:
0: mutex_lock() <-- holds the idr lock
0: rcu_read_lock()
0: p = idr_find(idr, index) <-- action p is valid (RCU protects IDR)
0: mutex_unlock() <-- releases the idr lock
1: refcount_dec_and_mutex_lock() <-- refcnt 1->0, mutex held
1: idr_remove(idr, index) <-- Action removed from IDR
1: mutex_unlock() <-- mutex released allowing us to delete the action
1: tcf_action_cleanup(p); kfree(p) <-- Kfrees p immediately, no deferral
0: refcount_inc_not_zero(&p->tcfa_refcnt) <-- ouch, UAF p points to freed memory
This patch fixes the race condition between NEWTFILTER and DELFILTER by
adding struct rcu_head to tc_action used in the deferral and introducing a
call_rcu() in the delete path to defer the final kfree().
Note: this is a revert of commit d7fb60b9cafb ("net_sched: get rid of tcfa_rcu")
but also modernization/simplification to directly use kfree_rcu().
Let's illustrate the new restored code path:
0: rcu_read_lock()
1: refcount_dec_and_mutex_lock() <-- refcnt 1->0, mutex held
1: idr_remove(idr, index)
1: mutex_unlock()
1: call_rcu(&p->tcfa_rcu, tcf_action_rcu_free) <-- defer kfree after grace period
0: p = idr_find(idr, index)
0: refcount_inc_not_zero(&p->tcfa_refcnt) <-- fails, refcnt already 0
1: rcu_read_unlock() <-- release so freeing can run after grace period
After CPU1 calls idr_remove(), the object is no longer reachable through the IDR.
CPU0's subsequent idr_find() will return NULL, and even if it still held a
stale pointer, the immediate kfree() is now deferred until after the RCU grace
period, so no UAF can occur.

ip_vs_edit_service() while unbinding the old scheduler clears
the svc->scheduler ptr after the scheduler module initiates
RCU callbacks. This can cause packets to use the old
scheduler at the time when svc->sched_data is already freed
after RCU grace period.
Fix it by clearing the ptr early in ip_vs_unbind_scheduler(),
before the done_service method schedules any RCU callbacks.
Also, if the new scheduler fails to initialize when replacing
the old scheduler, try to restore the old scheduler while still
returning the error code.

1) xfrm: route MIGRATE notifications to caller's netns
Thread the caller's netns through km_migrate() so that
MIGRATE notifications go to the issuing netns, fixing both the
init_net listener leak and MOBIKE notifications inside
non-init netns. From Maoyi Xie.
2) xfrm: ipcomp: Free destination pages on acomp errors
Move the out_free_req label up so that allocated destination
pages are released on decompression errors, not only on success.
From Herbert Xu.
3) xfrm: Check for underflow in xfrm_state_mtu
Reject configurations that cause xfrm_state_mtu() to underflow,
preventing a negative TFCPAD value from becoming a memset size
that triggers an out-of-bounds write of several terabytes.
From David Ahern.
4) xfrm: ah: use skb_to_full_sk in async output callbacks
Convert the possibly-incomplete skb->sk to a full socket pointer
in async AH callbacks so that a request_sock or timewait_sock
never reaches xfrm_output_resume() downstream consumers.
From Michael Bommarito.
5) Add and revert: esp: fix page frag reference leak on skb_to_sgvec failure
The patch does not fix te issue completely.
6) xfrm: esp: restore combined single-frag length gate
Check the aligned post-trailer combined length against a page limit
in the fast path, preventing skb_page_frag_refill() from falling
back to a page too small for the destination scatterlist.
From Jingguo Tan.
7) xfrm: iptfs: reset runtime state when cloning SAs
Reinitialise the clone's mode_data runtime objects before
publishing it, preventing queued skbs from being freed with
list state copied from the original SA when migration fails.
From Shaomin Chen.
8) xfrm: move policy_bydst RCU sync from per-netns .exit to .pre_exit
Flush policy tables and drain the workqueue in a .pre_exit handler
so that cleanup_net() pays one RCU grace period per batch instead
of one per namespace, fixing stalls at high CLONE_NEWNET rates.
From Usama Arif.
9) xfrm: input: hold netns during deferred transport reinjection
Take a netns reference when queueing deferred transport reinjection
work and drop it after the callback completes, keeping the skb->cb
net pointer valid until the deferred work runs.

Two concurrent madvise(MADV_HWPOISON) calls on the same hugetlb page can
trigger a recursive spinlock self-deadlock (AA deadlock) on hugetlb_lock
when racing with a concurrent unmap:
thread#0 thread#1
-------- --------
madvise(folio, MADV_HWPOISON)
-> poisons the folio successfully
madvise(folio, MADV_HWPOISON) unmap(folio)
try_memory_failure_hugetlb
get_huge_page_for_hwpoison
spin_lock_irq(&hugetlb_lock) <- held
__get_huge_page_for_hwpoison
hugetlb_update_hwpoison()
-> MF_HUGETLB_FOLIO_PRE_POISONED
goto out:
folio_put()
refcount: 1 -> 0
free_huge_folio()
spin_lock_irqsave(&hugetlb_lock)
-> AA DEADLOCK!
The out: path in __get_huge_page_for_hwpoison() calls folio_put() to drop
the GUP reference while the hugetlb_lock is still held by the hugetlb.c
wrapper get_huge_page_for_hwpoison(). If concurrent unmap has released
the page table mapping reference, folio_put() drops the folio refcount to
zero, triggering free_huge_folio() which attempts to re-acquire the
non-recursive hugetlb_lock.
Fix this by moving hugetlb_lock acquisition from the hugetlb.c wrapper
into get_huge_page_for_hwpoison(). Place spin_unlock_irq() before the
folio_put() at the out: label so the folio is always released outside the
lock.
