Pull networking fixes from Jakub Kicinski: "One more set of fixes from the networking tree: - add missing input validation in nl80211_del_key(), preventing out-of-bounds access - last minute fix / improvement of a MRP netlink (uAPI) interface introduced in 5.9 (current) release - fix "unresolved symbol" build error under CONFIG_NET w/o CONFIG_INET due to missing tcp_timewait_sock and inet_timewait_sock BTF. - fix 32 bit sub-register bounds tracking in the bpf verifier for OR case - tcp: fix receive window update in tcp_add_backlog() - openvswitch: handle DNAT tuple collision in conntrack-related code - r8169: wait for potential PHY reset to finish after applying a FW file, avoiding unexpected PHY behaviour and failures later on - mscc: fix tail dropping watermarks for Ocelot switches - avoid use-after-free in macsec code after a call to the GRO layer - avoid use-after-free in sctp error paths - add a device id for Cellient MPL200 WWAN card - rxrpc fixes: - fix the xdr encoding of the contents read from an rxrpc key - fix a BUG() for a unsupported encoding type. - fix missing _bh lock annotations. - fix acceptance handling for an incoming call where the incoming call is encrypted. - the server token keyring isn't network namespaced - it belongs to the server, so there's no need. Namespacing it means that request_key() fails to find it. - fix a leak of the server keyring" * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (21 commits) net: usb: qmi_wwan: add Cellient MPL200 card macsec: avoid use-after-free in macsec_handle_frame() r8169: consider that PHY reset may still be in progress after applying firmware openvswitch: handle DNAT tuple collision sctp: fix sctp_auth_init_hmacs() error path bridge: Netlink interface fix. net: wireless: nl80211: fix out-of-bounds access in nl80211_del_key() bpf: Fix scalar32_min_max_or bounds tracking tcp: fix receive window update in tcp_add_backlog() net: usb: rtl8150: set random MAC address when set_ethernet_addr() fails mptcp: more DATA FIN fixes net: mscc: ocelot: warn when encoding an out-of-bounds watermark value net: mscc: ocelot: divide watermark value by 60 when writing to SYS_ATOP net: qrtr: ns: Fix the incorrect usage of rcu_read_lock() rxrpc: Fix server keyring leak rxrpc: The server keyring isn't network-namespaced rxrpc: Fix accept on a connection that need securing rxrpc: Fix some missing _bh annotations on locking conn->state_lock rxrpc: Downgrade the BUG() for unsupported token type in rxrpc_read() rxrpc: Fix rxkad token xdr encoding ...
