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" * tag 'net-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (59 commits) selftests: forwarding: Fix ping failure due to short timeout MAINTAINERS: step down as netfilter maintainer netfilter: nf_tables: Fix a memory leak in nf_tables_updchain net: dsa: mt7530: fix handling of all link-local frames net: dsa: mt7530: fix link-local frames that ingress vlan filtering ports bpf: report RCU QS in cpumap kthread net: report RCU QS on threaded NAPI repolling rcu: add a helper to report consolidated flavor QS ionic: update documentation for XDP support lib/bitmap: Fix bitmap_scatter() and bitmap_gather() kernel doc netfilter: nf_tables: do not compare internal table flags on updates netfilter: nft_set_pipapo: release elements in clone only from destroy path octeontx2-af: Use separate handlers for interrupts octeontx2-pf: Send UP messages to VF only when VF is up. octeontx2-pf: Use default max_active works instead of one octeontx2-pf: Wait till detach_resources msg is complete octeontx2: Detect the mbox up or down message via register devlink: fix port new reply cmd type tcp: Clear req->syncookie in reqsk_alloc(). net/bnx2x: Prevent access to a freed page in page_pool ...
