When requesting ownership of the NIC (MAC/PHY control), we set up
the heartbeat to look stale:
/* Initialize heartbeat, set last response to 1 second in the past
* so that we will trigger a timeout if the firmware doesn't respond
*/
fbd->last_heartbeat_response = req_time - HZ;
fbd->last_heartbeat_request = req_time;
The response handler then sets:
fbd->last_heartbeat_response = jiffies;
for which we wait via:
fbnic_fw_init_heartbeat() -> fbnic_fw_heartbeat_current()
The scheme is a bit odd, but it should work in principle.
Fix the ordering of operations. We have to set up the stale heartbeat
before we send the message. Otherwise if the response is very fast
we will override it. This triggers on QEMU if we run on the core
that handles the IRQ, and results in ndo_open failing with ETIMEDOUT.
The change in ordering doesn't impact releasing the ownership.
Both ndo_stop and heartbeat check are under rtnl_lock.

====================
ipv6: fix error handling in disable_ipv6 sysctl
While working on a different IPv6 patch series I have spotted multiple
minor bugs around sysctl error handling and notifications. In general,
they are not serious issues.
In addition, there is one more issue in forwarding sysctl as it does not
check for CAP_NET_ADMIN for the namespace. I am keeping that patch out
of this series and I am aiming it at the net-next tree once it re-opens.
During v3, Ido's pointed out that it is unnecessary to reset the
position pointer when the return value is negative as at
new_sync_write() the ppos is only advanced when ret return value is
positive. That means we can get rid of that operation in ipv4/ipv6
sysctls. That is going to be sent to net-next too.

When changing the ignore_routes_with_linkdown sysctl for a specific
interface, the RTM_NEWNETCONF netlink notification was not being emitted
to userspace. Fix this by emitting the notification when needed.
In addition, fix bogus return value for successful "all" and specific
interface write operation leading to a wrong reset of the position
pointer.

When handling proxy_ndp, if rtnl_net_trylock() fails, the operation is
retried but as the value was already modified by the initial
proc_dointvec() call, the restarted syscall will read the newly modified
value as the 'old' state.
Fix this by taking the RTNL lock before parsing the input value if the
operation is a write.

au1000_close() calls free_irq() while aup->lock is still held with
spin_lock_irqsave(). free_irq() can sleep because it takes the IRQ
descriptor request mutex, so it does not belong inside the close-time
spinlocked section.
This was found by our static analysis tool and then confirmed by manual
review of the in-tree au1000_close() .ndo_stop path. The reviewed path
keeps aup->lock held across the MAC reset, queue stop and
free_irq(dev->irq, dev).
A directed runtime validation kept that ndo_stop carrier and the same
free_irq(dev->irq, dev) operation under the driver lock. Lockdep reported
"BUG: sleeping function called from invalid context" and "Invalid wait
context" while free_irq() was taking desc->request_mutex, with
au1000_close() and free_irq() on the stack.
Drop aup->lock before freeing the IRQ. The protected close-time work still
stops the device and queue before IRQ teardown, but the sleepable IRQ core
path now runs outside the spinlocked section.

When sctp_verify_init() encounters unrecognized parameters, it allocates an
err_chunk to report them. However, this chunk is leaked in several code
paths:
1. In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after
sctp_verify_init() has populated err_chunk, the function returns
immediately without freeing it.
2. In sctp_sf_do_unexpected_init(), the same leak occurs on the
security_sctp_assoc_request() failure path.
3. In sctp_sf_do_unexpected_init(), on the success path after copying
unrecognized parameters to the INIT-ACK, the function returns without
freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees
it.
Fix all three leaks by adding sctp_chunk_free(err_chunk) calls before
returning in the error paths and on the success path in
sctp_sf_do_unexpected_init().

tcf_classify() can return TC_ACT_CONSUMED while the skb is held by the
defragmentation engine (e.g. act_ct on out-of-order fragments). When
that happens the skb is no longer owned by the caller and must not be
touched again.
tcf_qevent_handle() did not handle TC_ACT_CONSUMED: it fell through the
switch and returned the skb to the caller as if classification had
passed. The only qdisc that wires up qevents today is RED, via three call sites
(qe_mark on RED_PROB_MARK/HARD_MARK, qe_early_drop on congestion_drop)
red_enqueue() was continuing to operate on an skb it no longer owns in this
case -- enqueueing it, dropping it, or updating statistics. Resulting in a UAF.
tc qdisc add dev eth0 root handle 1: red ... qevent early_drop block 10
tc filter add block 10 ... action ct
(with ct defrag enabled and traffic that produces out-of-order
fragments, e.g. a fragmented UDP stream)
Handle TC_ACT_CONSUMED in tcf_qevent_handle() the same way the ingress
and egress fast paths do: treat it as stolen and return NULL without
touching the skb. Unlike the TC_ACT_STOLEN case, the skb must not be
dropped/freed here, as it is no longer owned by us.

Test that an LWT encapsulation does not silently corrupt XDP metadata
sitting in the skb headroom. Exercise all three LWT dispatch paths:
- BPF LWT xmit prog reserves headroom on the LWT .xmit redirect,
- mpls pushes an MPLS label on the LWT .xmit redirect,
- seg6 in encap mode runs on the LWT .input redirect,
- ioam6 encap inserts an IOAM Hop-by-Hop option on LWT .output redirect.

skb metadata is meant for passing information between XDP and TC. It lives
in the skb headroom, immediately before skb->data. LWT programs cannot
access the __sk_buff->data_meta pseudo-pointer to metadata.
However, LWT encapsulation prepends outer headers, moving skb->data back
over the headroom where the metadata sits. On an RX-originated (forwarded)
packet that still carries XDP metadata this goes wrong in two different
ways, depending on the encap type:
1. Non-BPF LWT encaps (mpls, seg6, ioam6 ...) call skb_push()/skb_pull()
and silently overwrite the metadata that sits in the headroom.
2) BPF LWT xmit calls bpf_skb_change_head(), which uses skb_data_move().
That helper expects metadata immediately before skb->data. But since
the IP output path runs LWT xmit before neighbour output has built
the outgoing L2 header, for forwarded packets skb->data points at the
L3 header while skb_mac_header() still points at the old L2 header.
skb_data_move() sees metadata ending at skb_mac_header(), not before
skb->data, warns and clears metadata:
WARNING: CPU: 21 PID: 454557 at include/linux/skbuff.h:4609 skb_data_move+0x47/0x90

That is what happens, as for how to fix it - a received packet that
carries metadata can reach an encap through any of the three LWT
redirect modes:
LWTUNNEL_STATE_INPUT_REDIRECT
ip6_rcv_finish
dst_input
lwtunnel_input
LWTUNNEL_STATE_OUTPUT_REDIRECT
ip6_rcv_finish
dst_input
ip6_forward

ip6_rcv_finish
dst_input
ip6_forward
ip6_forward_finish
dst_output
ip6_output
ip6_finish_output
ip6_finish_output2
lwtunnel_xmit
Every encap funnels through the three LWT dispatch helpers, so drop the
metadata there, right before handing the skb to the encap op. This
single chokepoint covers all encap types and all three redirect modes:
- lwtunnel_input(): seg6, rpl, ila, seg6_local
- lwtunnel_output(): ioam6
- lwtunnel_xmit(): mpls, LWT BPF xmit
Alternatively, we could clear the metadata right after TC ingress hook.
That would require a compromise, however. Metadata would become
inaccessible from TC egress (in setups where it actually reaches the
hook it tact, that is without any L2 tunnels on path).

Steffen Klassert says:
====================
pull request (net): ipsec 2026-06-22
1) xfrm: use compat translator only for u64 alignment mismatch
Gate the XFRM_USER_COMPAT translator on COMPAT_FOR_U64_ALIGNMENT
so 32-bit compat tasks on arches whose 32-bit ABI already matches
the native 64-bit layout are no longer rejected with -EOPNOTSUPP.
From Sanman Pradhan.
2) net: af_key: initialize alg_key_len for IPComp states
Initialize the alg_key_len to 0 in the IPComp branch of
pfkey_msg2xfrm_state() so an uninitialized value cannot drive
xfrm_alg_len() into a slab-out-of-bounds kmemdup during
XFRM_MSG_MIGRATE. From Zijing Yin.
3) xfrm: Fix dev use-after-free in xfrm async resumption
Stash the original skb->dev and extend the RCU critical section
across xfrm_rcv_cb() and transport_finish() to prevent a
tunnel-device UAF and original-device refcount leak when a
callback replaces skb->dev. From Dong Chenchen.
4) xfrm: Fix xfrm state cache insertion race
Move the state-validity check inside xfrm_state_lock in the
input state cache insertion path so a state cannot be killed
between the check and the insert. From Herbert Xu.
5) xfrm: annotate data-races around xfrm_policy_count[] and xfrm_policy_default[]
Add READ_ONCE()/WRITE_ONCE() annotations on xfrm_policy_count
and xfrm_policy_default to silence the KCSAN data race reported
on net->xfrm.policy_count. From Eric Dumazet.
6) espintcp: use sk_msg_free_partial to fix partial send
Replace the manual skmsg accounting in espintcp with
sk_msg_free_partial() so the skmsg stays consistent on every
iteration and the partial-send accounting bugs go away.
From Sabrina Dubroca.
7) xfrm: validate selector family and prefixlen during match
Reject mismatched address families in xfrm_selector_match() and
bound prefixlen in addr4_match()/addr_match() to prevent the
shift-out-of-bounds syzbot reported when an AF_UNSPEC selector
with a large prefixlen is matched against an IPv4 flow.
From Eric Dumazet.

ksmbd_auth_ntlmv2() derives the NTLMv2 session key into
sess->sess_key before it verifies the NTLMv2 response.
ksmbd_decode_ntlmssp_auth_blob() then continues into KEY_XCH even
when ksmbd_auth_ntlmv2() failed.
With SMB3 multichannel binding, the failed authentication operates on
an existing session and the session setup error path does not expire
binding sessions. A client can send a binding session setup with a
bad NT proof and KEY_XCH and still modify sess->sess_key before
STATUS_LOGON_FAILURE is returned.
Relevant path:
smb2_sess_setup()
-> conn->binding = true
-> ntlm_authenticate()
-> session_user()
-> ksmbd_decode_ntlmssp_auth_blob()
-> ksmbd_auth_ntlmv2()
-> calc_ntlmv2_hash()
-> hmac_md5_usingrawkey(..., sess->sess_key)
-> crypto_memneq() returns mismatch
-> KEY_XCH arc4_crypt(..., sess->sess_key, ...)
-> out_err without expiring the binding session
Derive the base session key into a local buffer and copy it to
sess->sess_key only after the proof matches. Return immediately on
authentication failure so KEY_XCH is only processed after successful
authentication.
