Merge tag 'net-7.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
"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)"

Merge branch 'ipv6-fix-ecmp-route-failover-on-carrier-loss'

Sagarika Sharma says:

====================
ipv6: fix ECMP route failover on carrier loss

This patchset resolves an issue where established IPv6 connections are
unable to transition to alternative ECMP nexthops upon carrier loss.

Unlike IPv4, the IPv6 routing subsystem does not actively invalidate
cached destinations during a NETDEV_CHANGE event. Sockets persist
with dead routes, leading to stalled traffic or connection drops.

This series introduces a fix to trigger route invalidation by
updating the route serial number on link carrier loss and provides
a corresponding selftest to validate the failover behavior for IPv4
and IPv6.

selftest: net: Add test for TCP flow failover with ECMP routes.

Without the previous commit, TCP failed to switch to alternative
IPv6 routes immediately upon carrier loss.

It would persist with the dead route until reaching the threshold
net.ipv4.tcp_retries1, leading to unnecessary delays in failover.

Let's add a selftest for this scenario to ensure TCP fails over
immediately upon a carrier loss event.

Before:
TEST: TCP IPv4 failover [ OK ]
TEST: TCP IPv6 failover [FAIL]

After:
TEST: TCP IPv4 failover [ OK ]
TEST: TCP IPv6 failover [ OK ]
