There's a gap between when the buffer was grabbed and when it
potentially gets recycled, where if the list is empty, someone could've
upgraded it to a ring provided type. This can happen if the request
is forced via io-wq. The legacy recycling is missing checking if the

The NIX RAS health report path uses nix_af_rvu_err when handling the
NIX_AF_RVU_RAS case, so the report prints the ERR interrupt status rather
than the RAS interrupt status.

The NIX RAS health reporter recovery routine checks nix_af_rvu_int to
decide whether to re-enable NIX_AF_RAS interrupts. This is the RVU
interrupt status field and is unrelated to RAS events, so the recovery
flow may incorrectly skip re-enabling NIX_AF_RAS interrupts.
Check nix_af_rvu_ras instead before writing NIX_AF_RAS_ENA_W1S.

netfilter: updates for net
Due to large volume of backlogged patches its unlikely I will make the
2nd planned PR this week, so several legit fixes will be pushed back
to next week. Sorry for the inconvenience but I am out of ideas and
alternatives.
1) syzbot managed to add/remove devices to a flowtable, due to a bug in
the flowtable netdevice notifier this gets us a double-add and
eventually UaF when device is removed again (we only expect one
entry, duplicate remains past net_device end-of-life).
From Phil Sutter, bug added in 6.16.
2) Yiming Qian reports another nf_tables transaction handling bug:
in some cases error unwind misses to undo certain set elements,
resulting in refcount underflow and use-after-free, bug added in 6.4.
3) Jenny Guanni Qu found out-of-bounds read in pipapo set type.
While the value is never used, it still rightfully triggers KASAN
splats. Bug exists since this set type was added in 5.6.
4) a few x_tables modules contain copypastry tcp option parsing code which
can read 1 byte past the option area. This bug is ancient, fix from
David Dull.
5) nfnetlink_queue leaks kernel memory if userspace provides bad
NFQA_VLAN/NFQA_L2HDR attributes. From Hyunwoo Kim, bug stems from
from 4.7 days.
6) nfnetlink_cthelper has incorrect loop restart logic which may result
in reading one pointer past end of array. From 3.6 days, fix also from
Hyunwoo Kim.
7) xt_IDLETIMER v0 extension must reject working with timers added
by revision v1, else we get list corruption. Bug added in v5.7.
From Yifan Wu, Juefei Pu and Yuan Tan via Xin Lu.

neighbour: fix update of proxy neighbour
While re-reading some "old" patches I ran into a small change of
behavior in commit dc2a27e524 ("neighbour: Update pneigh_entry in
pneigh_create().").
The old behavior was not consistent between ->protocol and ->flags,
and didn't offer a way to clear protocol, so maybe it's better to
change that (7-years-old [1]) behavior. But then we should change
non-proxy neighbours as well to keep neigh/pneigh consistent.

Prior to commit dc2a27e524 ("neighbour: Update pneigh_entry in

that check was removed. This is a small change of user-visible

A user can set conn_timeout to any value via
setsockopt(TIPC_CONN_TIMEOUT), including values less than 4. When a
SYN is rejected with TIPC_ERR_OVERLOAD and the retry path in
tipc_sk_filter_connect() executes:
delay %= (tsk->conn_timeout / 4);
If conn_timeout is in the range [0, 3], the integer division yields 0,
and the modulo operation triggers a divide-by-zero exception, causing a
kernel oops/panic.
Fix this by clamping conn_timeout to a minimum of 4 at the point of use
in tipc_sk_filter_connect().

When IORING_SETUP_SQE_MIXED is used without IORING_SETUP_NO_SQARRAY,
the boundary check for 128-byte SQE operations in io_init_req()
validated the logical SQ head position rather than the physical SQE
index.
The existing check:
!(ctx->cached_sq_head & (ctx->sq_entries - 1))
ensures the logical position isn't at the end of the ring, which is
correct for NO_SQARRAY rings where physical == logical. However, when
sq_array is present, an unprivileged user can remap any logical
position to an arbitrary physical index via sq_array. Setting
sq_array[N] = sq_entries - 1 places a 128-byte operation at the last
physical SQE slot, causing the 128-byte memcpy in
io_uring_cmd_sqe_copy() to read 64 bytes past the end of the SQE
array.
Replace the cached_sq_head alignment check with a direct validation
of the physical SQE index, which correctly handles both sq_array and
NO_SQARRAY cases.

new rings and the old rings being freed.
Prevent this by adding a 2nd ->rings pointer, ->rings_rcu, which is
protected by RCU. The task work flags manipulation is inside RCU
already, and if the resize ring freeing is done post an RCU synchronize,
then there's no need to add locking to the fast path of task work
additions.
Note: this is only done for DEFER_TASKRUN, as that's the only setup mode
that supports ring resizing. If this ever changes, then they too need to
use the io_ctx_mark_taskrun() helper.

The acp_card_rt5682_init() and acp_card_rt5682s_init() functions did not
check the return values of clk_get(). This could lead to a kernel crash
when the invalid pointers are later dereferenced by clock core
functions.
Fix this by:
1. Changing clk_get() to the device-managed devm_clk_get().
2. Adding IS_ERR() checks immediately after each clock acquisition.

When refill_sheaf() partially fills one sheaf (e.g., fills 5 objects
but need to fill 10), it will update sheaf->size and return -ENOMEM.
However, the callers (alloc_full_sheaf() and __pcs_replace_empty_main())
directly call free_empty_sheaf() on failure, which only does kfree(sheaf),
causing the partially allocated objects memory in sheaf->objects[] leaked.
Fix this by calling sheaf_flush_unused() before free_empty_sheaf() to
free objects of sheaf->objects[]. And also add a WARN_ON() in
free_empty_sheaf() to catch any future cases where a non-empty sheaf is
being freed.

The bcmgenet EEE implementation is broken in several ways.
phy_support_eee() is never called, so the PHY never advertises EEE
and phylib never sets phydev->enable_tx_lpi. bcmgenet_mac_config()
checks priv->eee.eee_enabled to decide whether to enable the MAC
LPI logic, but that field is never initialised to true, so the MAC
never enters Low Power Idle even when EEE is negotiated - wasting
the power savings EEE is designed to provide. The only way to get
EEE working at all is a manual 'ethtool --set-eee eth0 eee on' after
every link-up, and even then bcmgenet_get_eee() immediately clobbers
the reported state because phy_ethtool_get_eee() overwrites
eee_enabled and tx_lpi_enabled with the uninitialised PHY eee_cfg
values. Finally, bcmgenet_mac_config() is only called on link-up,
so EEE is never disabled in hardware on link-down.
Fix all of this by removing the MAC-side EEE state tracking
(priv->eee) and aligning with the pattern used by other non-phylink
MAC drivers such as FEC.
Call phy_support_eee() in bcmgenet_mii_probe() so the PHY advertises
EEE link modes and phylib tracks negotiation state. Move the EEE
hardware control to bcmgenet_mii_setup(), which is called on every
link event, and drive it directly from phydev->enable_tx_lpi - the
flag phylib sets when EEE is negotiated and the user has not disabled
it. This enables EEE automatically once the link partner agrees and
disables it cleanly on link-down.
Make bcmgenet_get_eee() and bcmgenet_set_eee() pure passthroughs to
phy_ethtool_get_eee() and phy_ethtool_set_eee(), with the MAC
hardware register read/written for tx_lpi_timer. Drop struct
ethtool_keee eee from struct bcmgenet_priv.

genlmsg_reply() hands the reply skb to netlink, and
netlink_unicast() consumes it on all return paths, whether the
skb is queued successfully or freed on an error path.
net_shaper_nl_get_doit() and net_shaper_nl_cap_get_doit()
currently jump to free_msg after genlmsg_reply() fails and call
nlmsg_free(msg), which can hit the same skb twice.
Return the genlmsg_reply() error directly and keep free_msg
only for pre-reply failures.
