Hi,
The following patchset contains Netfilter fixes for net:
Patch #1 syzbot reports that nf_reinject() could be called without
rcu_read_lock() when flushing pending packets at nfnetlink
queue removal, from Eric Dumazet.
Patch #2 flushes ipset list:set when canceling garbage collection to
reference to other lists to fix a race, from Jozsef Kadlecsik.
Patch #3 restores q-in-q matching with nft_payload by reverting
f6ae9f120dad ("netfilter: nft_payload: add C-VLAN support").
Patch #4 fixes vlan mangling in skbuff when vlan offload is present
in skbuff, without this patch nft_payload corrupts packets
in this case.
Patch #5 fixes possible nul-deref in tproxy no IP address is found in
netdevice, reported by syzbot and patch from Florian Westphal.
Patch #6 removes a superfluous restriction which prevents loose fib
lookups from input and forward hooks, from Eric Garver.
My assessment is that patches #1, #2 and #5 address possible kernel
crash, anything else in this batch fixes broken features.
Please, pull these changes from:

Thanks.
