Merge tag 'net-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from CAN, netfilter, wireguard and IPsec.
I'd like to highlight [ lowlight? - Linus ] Florian W stepping down as
a netfilter maintainer due to constant stream of bug reports. Not sure
what we can do but IIUC this is not the first such case.
Current release - regressions:
- rxrpc: fix use of page_frag_alloc_align(), it changed semantics and
we added a new caller in a different subtree
- xfrm: allow UDP encapsulation only in offload modes
Current release - new code bugs:
- tcp: fix refcnt handling in __inet_hash_connect()
- Revert "net: Re-use and set mono_delivery_time bit for userspace
tstamp packets", conflicted with some expectations in BPF uAPI
Previous releases - regressions:
- ipv4: raw: fix sending packets from raw sockets via IPsec tunnels
- devlink: fix devlink's parallel command processing
- veth: do not manipulate GRO when using XDP
- esp: fix bad handling of pages from page_pool
Previous releases - always broken:
- report RCU QS for busy network kthreads (with Paul McK's blessing)
- tcp/rds: fix use-after-free on netns with kernel TCP reqsk
- virt: vmxnet3: fix missing reserved tailroom with XDP
Misc:
- couple of build fixes for Documentation"
