Merge tag 'net-6.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Including fixes from BPF and netfilter.
Current release - regressions:
- core: fix undefined behavior in netdev name allocation
- bpf: do not allocate percpu memory at init stage
- netfilter: nf_tables: split async and sync catchall in two
functions
- mptcp: fix possible NULL pointer dereference on close
Current release - new code bugs:
- eth: ice: dpll: fix initial lock status of dpll
Previous releases - regressions:
- bpf: fix precision backtracking instruction iteration
- af_unix: fix use-after-free in unix_stream_read_actor()
- tipc: fix kernel-infoleak due to uninitialized TLV value
- eth: bonding: stop the device in bond_setup_by_slave()
- eth: mlx5:
- fix double free of encap_header
- avoid referencing skb after free-ing in drop path
- eth: hns3: fix VF reset
- eth: mvneta: fix calls to page_pool_get_stats
Previous releases - always broken:
- core: set SOCK_RCU_FREE before inserting socket into hashtable
- bpf: fix control-flow graph checking in privileged mode
- eth: ppp: limit MRU to 64K
- eth: stmmac: avoid rx queue overrun
- eth: icssg-prueth: fix error cleanup on failing initialization
- eth: hns3: fix out-of-bounds access may occur when coalesce info is
read via debugfs
- eth: cortina: handle large frames
Misc:
- selftests: gso: support CONFIG_MAX_SKB_FRAGS up to 45"
