The issue is actually caused by skb trimming via sk_filter() in sctp_rcv().
In the reproducer, skb->len becomes 1 after sk_filter(), which bypassed the

if (skb->len < sizeof(struct sctphdr) + sizeof(struct sctp_chunkhdr) +

net: devmem: refresh devmem TX dst in case of route invalidation
The zero-copy Device Memory (Devmem) transmit path
relies on the socket's route cache (`dst_entry`) to
validate that the packet is being sent via the network
device to which the DMA buffer was bound.
However, this check incorrectly fails and returns `-ENODEV`
if the socket's route cache entry (`dst`) is merely missing
or expired (`dst == NULL`). This scenario is observed during
network events, such as when flow steering rules are deleted,
leading to a temporary route cache invalidation.
This patch fixes -ENODEV error for `net_devmem_get_binding()`
by doing the following:
1. It attempts to rebuild the route via `rebuild_header()`
if the route is initially missing (`dst == NULL`). This
allows the TCP/IP stack to recover from transient route
cache misses.
2. It uses `rcu_read_lock()` and `dst_dev_rcu()` to safely
access the network device pointer (`dst_dev`) from the
route, preventing use-after-free conditions if the
device is concurrently removed.
3. It maintains the critical safety check by validating
that the retrieved destination device (`dst_dev`) is
exactly the device registered in the Devmem binding
(`binding->dev`).
These changes prevent unnecessary ENODEV failures while
maintaining the critical safety requirement that the
Devmem resources are only used on the bound network device.

The DWMAC IP's VLAN tag insertion offload does not support inserting
STAG (802.1AD) and CTAG (802.1Q) types in bytes 13 and 14 using the
same MAC_VLAN_Incl and MAC_VLAN_Inner_Incl register configurations.
Currently, MAC_VLAN_Incl is configured to offload only STAG type
insertion. However, the DWMAC IP inserts a CTAG type when the inner
VLAN ID field of the descriptor is not configured, and a STAG type
when it is configured. This behavior is not documented and leads to
inconsistent double VLAN tagging.
Additionally, an unexpected CTAG with VLAN ID 0 is inserted, resulting
in frames like:

To avoid this undocumented and incorrect behavior, disable 802.1AD tag
insertion offload. Also, don't set CSVL bit. As per the data book,
when this bit is set, S-VLAN type (0x88A8) is inserted in the 13th and

====================
tls: Introduce and use RX async resync request cancel function
This series by Shahar introduces RX async resync request cancel function
in tls module, and uses it in mlx5e driver.
For a device-offloaded TLS RX connection, the TLS module increments
rcd_delta each time a new TLS record is received, tracking the distance
from the original resync request. In the meanwhile, the device is
queried and is expected to respond, asynchronously.
However, if the device response is delayed or fails (e.g due to unstable
connection and device getting out of tracking, hardware errors, resource
exhaustion etc.), the TLS module keeps logging and incrementing
rcd_delta, which can lead to a WARN() when rcd_delta exceeds the
threshold.
This series improves this code area by canceling the resync request when
spotting an issue with the device response.

net/mlx5e: kTLS, Cancel RX async resync request in error flows
When device loses track of TLS records, it attempts to resync by
monitoring records and requests an asynchronous resynchronization
from software for this TLS connection.
The TLS module handles such device RX resync requests by logging record
headers and comparing them with the record tcp_sn when provided by the
device. It also increments rcd_delta to track how far the current
record tcp_sn is from the tcp_sn of the original resync request.
If the device later responds with a matching tcp_sn, the TLS module
approves the tcp_sn for resync.
However, the device response may be delayed or never arrive,
particularly due to traffic-related issues such as packet drops or
reordering. In such cases, the TLS module remains unaware that resync
will not complete, and continues performing unnecessary work by logging
headers and incrementing rcd_delta, which can eventually exceed the
threshold and trigger a WARN(). For example, this was observed when the
device got out of tracking, causing
mlx5e_ktls_handle_get_psv_completion() to fail and ultimately leading
to the rcd_delta warning.
To address this, call tls_offload_rx_resync_async_request_cancel()
to cancel the resync request and stop resync tracking in such error
cases. Also, increment the tls_resync_req_skip counter to track these
cancellations.

net: phy: dp83869: fix STRAP_OPMODE bitmask
According to the TI DP83869HM datasheet Revision D (June 2025), section
7.6.1.41 STRAP_STS Register, the STRAP_OPMODE bitmask is bit [11:9].
Fix this.
In case the PHY is auto-detected via PHY ID registers, or not described
in DT, or, in case the PHY is described in DT but the optional DT property
"ti,op-mode" is not present, then the driver reads out the PHY functional
mode (RGMII, SGMII, ...) from hardware straps.
Currently, all upstream users of this PHY specify both DT compatible string
"ethernet-phy-id2000.a0f1" and ti,op-mode = <DP83869_RGMII_COPPER_ETHERNET>
property, therefore it seems no upstream users are affected by this bug.
The driver currently interprets bits [2:0] of STRAP_STS register as PHY
functional mode. Those bits are controlled by ANEG_DIS, ANEGSEL_0 straps
and an always-zero reserved bit. Systems that use RGMII-to-Copper functional
mode are unlikely to disable auto-negotiation via ANEG_DIS strap, or change
auto-negotiation behavior via ANEGSEL_0 strap. Therefore, even with this bug
in place, the STRAP_STS register content is likely going to be interpreted
by the driver as RGMII-to-Copper mode.
However, for a system with PHY functional mode strapping set to other mode
than RGMII-to-Copper, the driver is likely to misinterpret the strapping
as RGMII-to-Copper and misconfigure the PHY.
For example, on a system with SGMII-to-Copper strapping, the STRAP_STS
register reads as 0x0c20, but the PHY ends up being configured for
incompatible RGMII-to-Copper mode.

mptcp: various rare sending issues
Here are various fixes from Paolo, addressing very occasional issues on
the sending side:
- Patch 1: drop an optimisation that could lead to timeout in case of
race conditions. A fix for up to v5.11.
- Patch 2: fix stream corruption under very specific conditions.
A fix for up to v5.13.
- Patch 3: restore MPTCP-level zero window probe after a recent fix.
A fix for up to v5.16.
- Patch 4: new MIB counter to track MPTCP-level zero windows probe to
help catching issues similar to the one fixed by the previous patch.

mptcp: restore window probe
Since commit
72377ab2d671 ("mptcp: more conservative check for zero
probes") the MPTCP-level zero window probe check is always disabled, as
the TCP-level write queue always contains at least the newly allocated
skb.
Refine the relevant check tacking in account that the above condition
and that such skb can have zero length.

If a MSG_PEEK | MSG_WAITALL read operation consumes all the bytes in the

mptcp: drop bogus optimization in __mptcp_check_push()
Accessing the transmit queue without owning the msk socket lock is
inherently racy, hence __mptcp_check_push() could actually quit early
even when there is pending data.
That in turn could cause unexpected tx lock and timeout.
Dropping the early check avoids the race, implicitly relaying on later
tests under the relevant lock. With such change, all the other
mptcp_send_head() call sites are now under the msk socket lock and we
can additionally drop the now unneeded annotation on the transmit head
pointer accesses.

netconsole: Fix race condition in between reader and writer of userdata
The update_userdata() function constructs the complete userdata string
in nt->extradata_complete and updates nt->userdata_length. This data
is then read by write_msg() and write_ext_msg() when sending netconsole
messages. However, update_userdata() was not holding target_list_lock
during this process, allowing concurrent message transmission to read
partially updated userdata.
This race condition could result in netconsole messages containing
incomplete or inconsistent userdata - for example, reading the old
userdata_length with new extradata_complete content, or vice versa,
leading to truncated or corrupted output.
Fix this by acquiring target_list_lock with spin_lock_irqsave() before
updating extradata_complete and userdata_length, and releasing it after
both fields are fully updated. This ensures that readers see a
consistent view of the userdata, preventing corruption during concurrent
access.
The fix aligns with the existing locking pattern used throughout the
netconsole code, where target_list_lock protects access to target
fields including buf[] and msgcounter that are accessed during message
transmission.
Also get rid of the unnecessary variable complete_idx, which makes it
easier to bail out of update_userdata().

tcp: fix receive autotune again
Neal Cardwell found that recent kernels were having RWIN limited
issues, even when net.ipv4.tcp_rmem[2] was set to a very big value like
512MB.
He suspected that tcp_stream default buffer size (64KB) was triggering
heuristic added in
ea33537d8292 ("tcp: add receive queue awareness
in tcp_rcv_space_adjust()").
After more testing, it turns out the bug was added earlier
with commit
65c5287892e9 ("tcp: fix sk_rcvbuf overshoot").
I forgot once again that DRS has one RTT latency.
MPTCP also got the same issue.
This series :
- Prevents calling tcp_rcvbuf_grow() on some MPTCP subflows.
- adds rcv_ssthresh, window_clamp and rcv_wnd to trace_tcp_rcvbuf_grow().
- Refactors code in a patch with no functional changes.
- Fixes the issue in the final patch.

tcp: fix too slow tcp_rcvbuf_grow() action
While the blamed commits apparently avoided an overshoot,
they also limited how fast a sender can increase BDP at each RTT.
This is not exactly a revert, we do not add the 16 * tp->advmss
cushion we had, and we are keeping the out_of_order_queue
contribution.
Do the same in mptcp_rcvbuf_grow().
Tested:
emulated 50ms rtt (tcp_stream --tcp-tx-delay 50000), cubic 20 second flow.
net.ipv4.tcp_rmem set to "4096 131072
67000000"
perf record -a -e tcp:tcp_rcvbuf_grow sleep 20
perf script
Before:
We can see we fail to roughly double RWIN at each RTT.
Sender is RWIN limited while CWND is ramping up (before getting tcp_wmem
limited).

netfilter: nft_ct: add seqadj extension for natted connections
Sequence adjustment may be required for FTP traffic with PASV/EPSV modes.
due to need to re-write packet payload (IP, port) on the ftp control
connection. This can require changes to the TCP length and expected
seq / ack_seq.
The easiest way to reproduce this issue is with PASV mode.
Example ruleset:
table inet ftp_nat {
ct helper ftp_helper {
type "ftp" protocol tcp
l3proto inet
}
chain prerouting {
type filter hook prerouting priority 0; policy accept;
tcp dport 21 ct state new ct helper set "ftp_helper"
}
}
table ip nat {
chain prerouting {
type nat hook prerouting priority -100; policy accept;
tcp dport 21 dnat ip prefix to ip daddr map {
192.168.100.1 : 192.168.13.2/32 }
}
chain postrouting {
type nat hook postrouting priority 100 ; policy accept;
tcp sport 21 snat ip prefix to ip saddr map {
192.168.13.2 : 192.168.100.1/32 }
}
}
Note that the ftp helper gets assigned *after* the dnat setup.
The inverse (nat after helper assign) is handled by an existing
check in nf_nat_setup_info() and will not show the problem.

netfilter: nft_ct: enable labels for get case too
conntrack labels can only be set when the conntrack has been created

For older iptables (connlabel match), adding an "-m connlabel" rule
turns on the ctlabel extension allocation for all future conntrack
entries.
For nftables, its only enabled for 'ct label set foo', but not for
'ct label foo' (i.e. check).
But users could have a ruleset that only checks for presence, and rely
on userspace to set a label bit via ctnetlink infrastructure.
This doesn't work without adding a dummy 'ct label set' rule.
We could also enable extension infra for the first (failing) ctnetlink
request, but unlike ruleset we would not be able to disable the
extension again.
Therefore turn on ctlabel extension allocation if an nftables ruleset
checks for a connlabel too.

drivers/pci/pcie/err.c/report_error_detected() says:
If any device in the subtree does not have an error_detected

error callbacks of any device in the subtree, and will
exit in the disconnected error state.
Therefore, when the hibmcge device and other devices that do not
support the error_detected callback are under the same subtree,
hibmcge will be unable to do slot_reset even for non-fatal errors.

dpll: fix device-id-get and pin-id-get to return errors properly
The device-id-get and pin-id-get handlers were ignoring errors from
the find functions and sending empty replies instead of returning
error codes to userspace.
When dpll_device_find_from_nlattr() or dpll_pin_find_from_nlattr()
returned an error (e.g., -EINVAL for "multiple matches" or -ENODEV
for "not found"), the handlers checked `if (!IS_ERR(ptr))` and
skipped adding the device/pin handle to the message, but then still
sent the empty message as a successful reply.
This caused userspace tools to receive empty responses with id=0
instead of proper netlink errors with extack messages like
"multiple matches".
The bug is visible via strace, which shows the kernel sending TWO
netlink messages in response to a single request:
1. Empty reply (20 bytes, just header, no attributes):
recvfrom(3, [{nlmsg_len=20, nlmsg_type=dpll, nlmsg_flags=0, ...},
{cmd=0x7, version=1}], ...)
2. NLMSG_ERROR ACK with extack (because of NLM_F_ACK flag):
recvfrom(3, [{nlmsg_len=60, nlmsg_type=NLMSG_ERROR,
nlmsg_flags=NLM_F_CAPPED|NLM_F_ACK_TLVS, ...},
[{error=0, msg={...}},
[{nla_type=NLMSGERR_ATTR_MSG}, "multiple matches"]]], ...)
The C YNL library parses the first message, sees an empty response,
and creates a result object with calloc() which zero-initializes all
fields, resulting in id=0.
The Python YNL library parses both messages and displays the extack
from the second NLMSG_ERROR message.
Fix by checking `if (IS_ERR(ptr))` first and returning the error
code immediately, so that netlink properly sends only NLMSG_ERROR with
the extack message to userspace. After this fix, both C and Python
YNL tools receive only the NLMSG_ERROR and behave consistently.
This affects:
- DPLL_CMD_DEVICE_ID_GET: now properly returns error when multiple
devices match the criteria (e.g., same module-name + clock-id)
- DPLL_CMD_PIN_ID_GET: now properly returns error when multiple pins
match the criteria (e.g., same module-name)
Before fix:
$ dpll pin id-get module-name ice
0 (wrong - should be error, there are 17 pins with module-name "ice")
After fix:
$ dpll pin id-get module-name ice
Error: multiple matches
(correct - kernel reports the ambiguity via extack)

igc: power up the PHY before the link test
The current implementation of the igc driver doesn't power up the PHY
before the link test in igc_ethtool_diag_test(), causing the link test
to always report FAIL when admin state is down and the PHY is
consequently powered down.
To test the link state regardless of admin state, power up the PHY
before the link test in the offline test path. After the link test, the
original PHY state is restored by igc_reset(), so additional code which
explicitly restores the original state is not necessary.
Note that this change is applied only for the offline test path. This is
because in the online path we shouldn't interrupt normal networking
operation and powering up the PHY and restoring the original state would
interrupt that.
This implementation also uses igc_power_up_phy_copper() without checking
the media type, since igc devices are currently only copper devices and
the function is called in other places without checking the media type.
Furthermore, the powering up is on a best-effort basis, that is, we
don't handle failures of powering up (e.g. bus error) and just let the
test report FAIL.
Tested on Intel Corporation Ethernet Controller I226-V (rev 04) with
cable connected and link available.

ixgbe: fix memory leak and use-after-free in ixgbe_recovery_probe()
The error path of ixgbe_recovery_probe() has two memory bugs.
For non-E610 adapters, the function jumps to clean_up_probe without
calling devlink_free(), leaking the devlink instance and its embedded
adapter structure.
For E610 adapters, devlink_free() is called at shutdown_aci, but
clean_up_probe then accesses adapter->state, sometimes triggering
use-after-free because adapter is embedded in devlink. This UAF is
similar to the one recently reported in ixgbe_remove(). (Link)
Fix both issues by moving devlink_free() after adapter->state access,
aligning with the cleanup order in ixgbe_probe().

ice: fix usage of logical PF id
In some devices, the function numbers used are non-contiguous. For
example, here is such configuration for E825 device:
root@/home/root# lspci -v | grep Eth
0a:00.0 Ethernet controller: Intel Corporation Ethernet Connection
E825-C for backplane (rev 04)
0a:00.1 Ethernet controller: Intel Corporation Ethernet Connection

E825-C 10GbE (rev 04)
0a:00.5 Ethernet controller: Intel Corporation Ethernet Connection
E825-C 10GbE (rev 04)
When distributing RSS and FDIR masks, which are global resources across
the active devices, it is required to have a contiguous PF id, which can
be described as a logical PF id. In the case above, function 0 would
have a logical PF id of 0, function 1 would have a logical PF id
of 1, and functions 4 and 5 would have a logical PF ids 2 and 3
respectively.
Using logical PF id can properly describe which slice of resources can
be used by a particular PF.
The 'function id' to 'logical id' mapping has been introduced with the
commit
015307754a19 ("ice: Support VF queue rate limit and quanta size
configuration"). However, the usage of 'logical_pf_id' field was
unintentionally skipped for profile mask configuration.
Fix it by using 'logical_pf_id' instead of 'pf_id' value when configuring
masks.
Without that patch, wrong indexes, i.e. out of range for given PF, can
be used while configuring resources masks, which might lead to memory
corruption and undefined driver behavior.

ice: fix destination CGU for dual complex E825
On dual complex E825, only complex 0 has functional CGU (Clock
Generation Unit), powering all the PHYs.
SBQ (Side Band Queue) destination device 'cgu' in current implementation
points to CGU on current complex and, in order to access primary CGU
from the secondary complex, the driver should use 'cgu_peer' as
a destination device in read/write CGU registers operations.
Define new 'cgu_peer' (15) as RDA (Remote Device Access) client over
SB-IOSF interface and use it as device target when accessing CGU from
secondary complex.
This problem has been identified when working on recovery clock
enablement [1]. In existing implementation for E825 devices, only PF0,
which is clock owner, is involved in CGU configuration, thus the
problem was not exposed to the user.

tools: ynl: fix string attribute length to include null terminator
The ynl_attr_put_str() function was not including the null terminator
in the attribute length calculation. This caused kernel to reject
CTRL_CMD_GETFAMILY requests with EINVAL:
"Attribute failed policy validation".
For a 4-character family name like "dpll":
- Sent: nla_len=8 (4 byte header + 4 byte string without null)
- Expected: nla_len=9 (4 byte header + 5 byte string with null)
The bug was introduced in commit
15d2540e0d62 ("tools: ynl: check for
overflow of constructed messages") when refactoring from stpcpy() to
strlen(). The original code correctly included the null terminator:
end = stpcpy(ynl_attr_data(attr), str);
attr->nla_len = NLA_HDRLEN + NLA_ALIGN(end -
(char *)ynl_attr_data(attr));
Since stpcpy() returns a pointer past the null terminator, the length
included it. The refactored version using strlen() omitted the +1.
The fix also removes NLA_ALIGN() from nla_len calculation, since
nla_len should contain actual attribute length, not aligned length.
Alignment is only for calculating next attribute position. This makes
the code consistent with ynl_attr_put().
CTRL_ATTR_FAMILY_NAME uses NLA_NUL_STRING policy which requires
null terminator. Kernel validates with memchr() and rejects if not
found.

smb: server: call smb_direct_post_recv_credits() when the negotiation is done
We now activate sc->recv_io.posted.refill_work and sc->idle.immediate_work
only after a successful negotiation, before sending the negotiation
response.
It means the queue_work(sc->workqueue, &sc->recv_io.posted.refill_work)
in put_recvmsg() of the negotiate request, is a no-op now.
It also means our explicit smb_direct_post_recv_credits() will
have queue_work(sc->workqueue, &sc->idle.immediate_work) as no-op.
This should make sure we don't have races and post any immediate
data_transfer message that tries to grant credits to the peer,
before we send the negotiation response, as that will grant
the initial credits to the peer.

handle_response() dereferences the payload as a 4-byte handle without
verifying that the declared payload size is at least 4 bytes. A malformed

net: phy: dp83867: Disable EEE support as not implemented
While the DP83867 PHYs report EEE capability through their feature
registers, the actual hardware does not support EEE (see Links).
When the connected MAC enables EEE, it causes link instability and
communication failures.
The issue is reproducible with a iMX8MP and relevant stmmac ethernet port.
Since the introduction of phylink-managed EEE support in the stmmac driver,
EEE is now enabled by default, leading to issues on systems using the
DP83867 PHY.
Call phy_disable_eee during phy initialization to prevent EEE from being
enabled on DP83867 PHYs.

Bluetooth: rfcomm: fix modem control handling
The RFCOMM driver confuses the local and remote modem control signals,
which specifically means that the reported DTR and RTS state will
instead reflect the remote end (i.e. DSR and CTS).
This issue dates back to the original driver (and a follow-on update)
merged in 2002, which resulted in a non-standard implementation of
TIOCMSET that allowed controlling also the TS07.10 IC and DV signals by
mapping them to the RI and DCD input flags, while TIOCMGET failed to
return the actual state of DTR and RTS.
Note that the bogus control of input signals in tiocmset() is just
dead code as those flags will have been masked out by the tty layer
since 2003.

Bluetooth: fix corruption in h4_recv_buf() after cleanup
A different structure is stored in drvdata for the drivers which used
that duplicate function, but h4_recv_buf() assumes drvdata is always an
hci_uart structure.
Consequently, alignment and padding are now randomly corrupted for
btmtkuart, btnxpuart, and bpa10x in h4_recv_buf(), causing erratic
breakage.
Fix this by making the hci_uart structure the explicit argument to
h4_recv_buf(). Every caller already has a reference to hci_uart, and
already obtains the hci_hdev reference through it, so this actually
eliminates a redundant pointer indirection for all existing callers.
