Pull scheduler fixes from Ingo Molnar:

 - Fix spurious failures in rseq self-tests (Mark Brown)

 - Fix rseq rseq::cpu_id_start ABI regression due to TCMalloc's creative
   use of the supposedly read-only field

   The fix is to introduce a new ABI variant based on a new (larger)
   rseq area registration size, to keep the TCMalloc use of rseq
   backwards compatible on new kernels (Thomas Gleixner)

 "Including fixes from Netfilter, IPsec, Bluetooth and WiFi.

  Current release - fix to a fix:

   - ipmr: add __rcu to netns_ipv4.mrt, make sure we hold the RCU lock
     in all relevant places

  Current release - new code bugs:

   - fixes for the recently added resizable hash tables

   - ipv6: make sure we default IPv6 tunnel drivers to =m now that IPv6
     itself is built in

   - drv: octeontx2-af: fixes for parser/CAM fixes

  Previous releases - regressions:

   - phy: micrel: fix LAN8814 QSGMII soft reset

   - wifi:
       - cw1200: revert "Fix locking in error paths"
       - ath12k: fix crash on WCN7850, due to adding the same queue
         buffer to a list multiple times

  Previous releases - always broken:

   - number of info leak fixes

   - ipv6: implement limits on extension header parsing

   - wifi: number of fixes for missing bound checks in the drivers

   - Bluetooth: fixes for races and locking issues

   - af_unix:
       - fix an issue between garbage collection and PEEK
       - fix yet another issue with OOB data

   - xfrm: esp: avoid in-place decrypt on shared skb frags

   - netfilter: replace skb_try_make_writable() by skb_ensure_writable()

   - openvswitch: vport: fix race between tunnel creation and linking
     leading to invalid memory accesses (type confusion)

   - drv: amd-xgbe: fix PTP addend overflow causing frozen clock

  Misc:

   - sched/isolation: make HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN
     (for relevant IPVS change)"

When pm_netlink.sh is executed with '-i', 'ip mptcp' is used instead of
'pm_nl_ctl'. IPRoute2 doesn't support the 'unknown' flag, which has only
been added to 'pm_nl_ctl' for this specific check: to ensure that the
kernel ignores such unsupported flag.

No reason to add this flag to 'ip mptcp'. Then, this check should be
skipped when 'ip mptcp' is used.

Using '${?}' inside the if-statement to check the returned value from
the command that was evaluated as part of the if-statement is not
correct: here, '${?}' will be linked to the previous instruction, not
the one that is expected here (${cmd}).

Instead, simply mark the error, except if an error is expected. If
that's the case, 1 can be passed as the 4th argument of this helper.
Three checks from pm_netlink.sh expect an error.

While at it, improve the error message when the command unexpectedly
fails or succeeds.

Note that we could expect a specific returned value, but the checks
currently expecting an error can be used with 'ip mptcp' or 'pm_nl_ctl',
and these two tools don't return the same error code.

pull request (net): ipsec 2026-05-05

1. Fix an IPv6 encapsulation error path that leaked route references
   when UDPv6 ESP decapsulation resolved to an error route.
   From Yilin Zhu.

2. Fix AH with ESN on async crypto paths by accounting for the extra
   high-order sequence number when reconstructing the temporary
   authentication layout in the completion callbacks.
   From Michael Bomarito.

3. Fix XFRM output so it does not overwrite already-correct inner header
   pointers when a tunnel layer such as VXLAN has already saved them.
   The fix comes with new selftests. From Cosmin Ratiu.

4. Add the missing native payload size entry for XFRM_MSG_MAPPING in the
   compat translation path. From Ruijie Li.

5. Harden __xfrm_state_delete() against repeated or inconsistent unhashing
   of state list nodes by keying the removal on actual list membership and
   using delete-and-init helpers. From Michal Kosiorek.

6. Prevent ESP from decrypting shared splice-backed skb fragments in place
   by marking UDP splice frags as shared and forcing copy-on-write in ESP
   input when needed. From Kuan-Ting Chen.
