Merge tag 'net-5.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.11-rc5, including fixes from bpf, wireless, and
can trees.
Current release - regressions:
- nfc: nci: fix the wrong NCI_CORE_INIT parameters
Current release - new code bugs:
- bpf: allow empty module BTFs
Previous releases - regressions:
- bpf: fix signed_{sub,add32}_overflows type handling
- tcp: do not mess with cloned skbs in tcp_add_backlog()
- bpf: prevent double bpf_prog_put call from bpf_tracing_prog_attach
- bpf: don't leak memory in bpf getsockopt when optlen == 0
- tcp: fix potential use-after-free due to double kfree()
- mac80211: fix encryption issues with WEP
- devlink: use right genl user_ptr when handling port param get/set
- ipv6: set multicast flag on the multicast route
- tcp: fix TCP_USER_TIMEOUT with zero window
Previous releases - always broken:
- bpf: local storage helpers should check nullness of owner ptr passed
- mac80211: fix incorrect strlen of .write in debugfs
- cls_flower: call nla_ok() before nla_next()
- skbuff: back tiny skbs with kmalloc() in __netdev_alloc_skb() too"
