36eae0956f netfilter: nft_ct: drop pending enqueued packets on removal
Packets sitting in nfqueue might hold a reference to:

- templates that specify the conntrack zone, because a percpu area is
  used and module removal is possible.
- conntrack timeout policies and helper, where object removal leave
  a stale reference.

Since these objects can just go away, drop enqueued packets to avoid
stale reference to them.

If there is a need for finer grain removal, this logic can be revisited
to make selective packet drop upon dependencies.

1e3a359316 netfilter: nf_conntrack_h323: fix OOB read in decode_int() CONS case
In decode_int(), the CONS case calls get_bits(bs, 2) to read a length
value, then calls get_uint(bs, len) without checking that len bytes
remain in the buffer. The existing boundary check only validates the
2 bits for get_bits(), not the subsequent 1-4 bytes that get_uint()
reads. This allows a malformed H.323/RAS packet to cause a 1-4 byte
slab-out-of-bounds read.

Add a boundary check for len bytes after get_bits() and before
get_uint().

598adea720 netfilter: revert nft_set_rbtree: validate open interval overlap
This reverts commit 648946966a ("netfilter: nft_set_rbtree: validate
open interval overlap").

There have been reports of nft failing to laod valid rulesets after this
patch was merged into -stable.

I can reproduce several such problem with recent nft versions, including
nft 1.1.6 which is widely shipped by distributions.

We currently have little choice here.
This commit can be resurrected at some point once the nftables fix that
triggers the false overlap positive has appeared in common distros
(see e83e32c8d1cd ("mnl: restore create element command with large batches" in
 nftables.git).

fbce58e719 netfilter: nf_conntrack_sip: fix Content-Length u32 truncation in sip_help_tcp()
sip_help_tcp() parses the SIP Content-Length header with
simple_strtoul(), which returns unsigned long, but stores the result in
unsigned int clen.  On 64-bit systems, values exceeding UINT_MAX are
silently truncated before computing the SIP message boundary.

For example, Content-Length 4294967328 (2^32 + 32) is truncated to 32,
causing the parser to miscalculate where the current message ends.  The
loop then treats trailing data in the TCP segment as a second SIP
message and processes it through the SDP parser.

Fix this by changing clen to unsigned long to match the return type of
simple_strtoul(), and reject Content-Length values that exceed the
remaining TCP payload length.

f900e1d77e netfilter: conntrack: add missing netlink policy validations
Hyunwoo Kim reports out-of-bounds access in sctp and ctnetlink.

These attributes are used by the kernel without any validation.
Extend the netlink policies accordingly.

Quoting the reporter:
  nlattr_to_sctp() assigns the user-supplied CTA_PROTOINFO_SCTP_STATE
  value directly to ct->proto.sctp.state without checking that it is
  within the valid range. [..]

  and: ... with exp->dir = 100, the access at
  ct->master->tuplehash[100] reads 5600 bytes past the start of a
  320-byte nf_conn object, causing a slab-out-of-bounds read confirmed by
  UBSAN.

5cb81eeda9 netfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct()
ctnetlink_dump_exp_ct() stores a conntrack pointer in cb->data for the
netlink dump callback ctnetlink_exp_ct_dump_table(), but drops the
conntrack reference immediately after netlink_dump_start().  When the
dump spans multiple rounds, the second recvmsg() triggers the dump
callback which dereferences the now-freed conntrack via nfct_help(ct),
leading to a use-after-free on ct->ext.

The bug is that the netlink_dump_control has no .start or .done
callbacks to manage the conntrack reference across dump rounds.  Other
dump functions in the same file (e.g. ctnetlink_get_conntrack) properly
use .start/.done callbacks for this purpose.

Fix this by adding .start and .done callbacks that hold and release the
conntrack reference for the duration of the dump, and move the
nfct_help() call after the cb->args[0] early-return check in the dump
callback to avoid dereferencing ct->ext unnecessarily.

Code allocates standard kernel memory to pass to the MPAM, which expects

c1376f1ff3 arm_mpam: Disable preemption when making accesses to fake MSC in kunit test
Accesses to MSC must be made from a cpu that is affine to that MSC and the
driver checks this in __mpam_write_reg() using smp_processor_id(). A fake
in-memory MSC is used for testing. When using that, it doesn't matter which
cpu we access it from but calling smp_processor_id() from a preemptible
context gives warnings when running with CONFIG_DEBUG_PREEMPT.

Add a test helper that wraps mpam_reset_msc_bitmap() with preemption
disabled to ensure all (fake) MSC accesses are made with preemption
disabled.

4ad79c874e arm_mpam: Fix null pointer dereference when restoring bandwidth counters
When an MSC supporting memory bandwidth monitoring is brought offline and
then online, mpam_restore_mbwu_state() calls __ris_msmon_read() via ipi to
restore the configuration of the bandwidth counters. It doesn't care about
the value read, mbwu_arg.val, and doesn't set it leading to a null pointer
dereference when __ris_msmon_read() adds to it. This results in a kernel
oops with a call trace such as:

Call trace:
__ris_msmon_read+0x19c/0x64c (P)

any side effects occur, to ensure the operation is only allowed for
actual TDLS peers.

95acbb0746 drm/i915/dp: Simplify forcing a link retraining
Since both the DP SST and MST HPD IRQ handlers call
intel_dp_handle_link_service_irq() with LINK_STATUS_CHANGED set in
irq_mask if intel_dp->link.force_retrain is set, checking for the former
flag is sufficient to determine if the link status needs to be checked
(which includes retraining the link if this is forced); remove checking
for the latter flag.

Since LINK_STATUS_CHANGED is currently set unconditionally for DP SST,
extend the related comment to note that it must be set if
intel_dp->link.force_retrain is set (in case setting LINK_STATUS_CHANGED
becomes conditional on DPCD_REV).

e41e992cb6 drm/i915/dp_mst: Fix forced link retrain handling in MST HPD IRQ handler
Handling of a forced link retraining debugfs request via the DP MST HPD
IRQ handler is incorrectly skipped, if the IRQ handler doesn't see any
HPD IRQs raised by the sink. Fix this by ensuring that the request is
always handled (in the Fixes: commit below by directly calling
intel_dp_check_link_state(), later by the same call moved to
intel_dp_handle_link_service_irq()).

9573a365ff btrfs: log new dentries when logging parent dir of a conflicting inode
If we log the parent directory of a conflicting inode, we are not logging
the new dentries of the directory, so when we finish we have the parent
directory's inode marked as logged but we did not log its new dentries.
As a consequence if the parent directory is explicitly fsynced later and
it does not have any new changes since we logged it, the fsync is a no-op
and after a power failure the new dentries are missing.

Example scenario:

  $ mkdir foo

  $ sync

  $rmdir foo

  $ mkdir dir1
  $ mkdir dir2

  # A file with the same name and parent as the directory we just deleted
  # and was persisted in a past transaction. So the deleted directory's
  # inode is a conflicting inode of this new file's inode.
  $ touch foo

  $ ln foo dir2/link

  # The fsync on dir2 will log the parent directory (".") because the
  # conflicting inode (deleted directory) does not exists anymore, but it
  # it does not log its new dentries (dir1).
  $ xfs_io -c "fsync" dir2

  # This fsync on the parent directory is no-op, since the previous fsync
  # logged it (but without logging its new dentries).
  $ xfs_io -c "fsync" .

  <power failure>

  # After log replay dir1 is missing.

Fix this by ensuring we log new dir dentries whenever we log the parent
directory of a no longer existing conflicting inode.

A test case for fstests will follow soon.

Don't hold the device_list_mutex while calling into
btrfs_get_dev_zone_info() in btrfs_get_dev_zone_info_all_devices() to
mitigate the issue. This is safe, as no other thread can touch the device

Function `btrfs_relocate_chunk()` always passes verbose=true to
`btrfs_relocate_block_group()` instead of the `verbose` parameter passed
into it by it's callers.

While user initiated rebalancing should be logged in the Kernel's log
buffer. This causes excessive log spamming from automatic rebalancing,
e.g. on zoned filesystems running low on usable space.

daf8e3b253 xfrm: Fix work re-schedule after cancel in xfrm_nat_keepalive_net_fini()
After cancel_delayed_work_sync() is called from
xfrm_nat_keepalive_net_fini(), xfrm_state_fini() flushes remaining
states via __xfrm_state_delete(), which calls
xfrm_nat_keepalive_state_updated() to re-schedule nat_keepalive_work.

The following is a simple race scenario:

           cpu0                             cpu1

cleanup_net() [Round 1]
  ops_undo_list()
    xfrm_net_exit()
      xfrm_nat_keepalive_net_fini()
        cancel_delayed_work_sync(nat_keepalive_work);
      xfrm_state_fini()
        xfrm_state_flush()
          xfrm_state_delete(x)
            __xfrm_state_delete(x)
              xfrm_nat_keepalive_state_updated(x)
                schedule_delayed_work(nat_keepalive_work);
  rcu_barrier();
  net_complete_free();
  net_passive_dec(net);
    llist_add(&net->defer_free_list, &defer_free_list);

cleanup_net() [Round 2]
  rcu_barrier();
  net_complete_free()
    kmem_cache_free(net_cachep, net);
                                     nat_keepalive_work()
                                       // on freed net

To prevent this, cancel_delayed_work_sync() is replaced with
disable_delayed_work_sync().

5ff89ef425 dt-bindings: rtc: isl12026: convert to YAML schema
Convert the ISL12026 RTC binding from text format to YAML schema.
Remove the legacy text binding.

The new schema enables dtbs_check validation.

995a418a6c auxdisplay: lcd2s: add error handling for i2c transfers
The lcd2s_print() and lcd2s_gotoxy() functions currently ignore the
return value of lcd2s_i2c_master_send(), which can fail. This can lead
to silent data loss or incorrect cursor positioning.

Add proper error checking: if the number of bytes sent does not match
the expected length, return -EIO; otherwise propagate any error code
from the I2C transfer.

057c0944e0 ARM: dts: renesas: armadillo800eva: Enable SDHI1
The Armadillo-800EVA board provides an SD card slot and an AWL13 SDIO
interface connected to the SDHI1 controller.  Routing between these two
interfaces is controlled by a mechanical DIP switch and a set of
multiplexers.

To support this, add:
  - A fixed 3.3V regulator for SDHI1 power, controlled by PORT16 (G2),
  - SDHI1 pinmux groups for data, control, and card detection,
  - A gpio-hog for PORT6 (J5) to control the SDHI1/AWLAN multiplexer.

PORT176 (N21) is already configured as output-high in this DTS (via
lcd0-mux-hog), routing the SDSLOT2_ENABLE signal to PORT6.  Since the
hardware includes an external 10k pull-up resistor (R94) on this line,
PORT6 is configured as an input to allow the physical DIP switch to
determine the routing without SoC interference.

Both configurations have been verified:
  - SD card (CON8): detected as mmcblk1, high-speed SDHC,
  - SDIO (CON14): detected as mmc1, high-speed SDIO.
