Merge tag 'net-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.13-rc1, including fixes from bpf, can and
netfilter trees. Self-contained fixes, nothing risky.

Current release - new code bugs:

- dsa: ksz: fix a few bugs found by static-checker in the new driver

- stmmac: fix frame preemption handshake not triggering after
interface restart

Previous releases - regressions:

- make nla_strcmp handle more then one trailing null character

- fix stack OOB reads while fragmenting IPv4 packets in openvswitch
and net/sched

- sctp: do asoc update earlier in sctp_sf_do_dupcook_a

- sctp: delay auto_asconf init until binding the first addr

- stmmac: clear receive all(RA) bit when promiscuous mode is off

- can: mcp251x: fix resume from sleep before interface was brought up

Previous releases - always broken:

- bpf: fix leakage of uninitialized bpf stack under speculation

- bpf: fix masking negation logic upon negative dst register

- netfilter: don't assume that skb_header_pointer() will never fail

- only allow init netns to set default tcp cong to a restricted algo

- xsk: fix xp_aligned_validate_desc() when len == chunk_size to avoid
false positive errors

- ethtool: fix missing NLM_F_MULTI flag when dumping

- can: m_can: m_can_tx_work_queue(): fix tx_skb race condition

- sctp: fix a SCTP_MIB_CURRESTAB leak in sctp_sf_do_dupcook_b

- bridge: fix NULL-deref caused by a races between assigning
rx_handler_data and setting the IFF_BRIDGE_PORT bit

Latecomer:

- seg6: add counters support for SRv6 Behaviors"

for IPv4 packets, sch_fragment() uses a temporary struct dst_entry. Then,
in the following call graph:

ip_do_fragment()
ip_skb_dst_mtu()
ip_dst_mtu_maybe_forward()
ip_mtu_locked()

the pointer to struct dst_entry is used as pointer to struct rtable: this
turns the access to struct members like rt_mtu_locked into an OOB read in
the stack. Fix this changing the temporary variable used for IPv4 packets
in sch_fragment(), similarly to what is done for IPv6 few lines below.
