Pull networking fixes from David Miller:
1) Fix TTL offset calculation in mac80211 mesh code, from Peter Oh.
2) Fix races with procfs in ipt_CLUSTERIP, from Cong Wang.
3) Memory leak fix in lpm_trie BPF map code, from Yonghong Song.
4) Need to use GFP_ATOMIC in BPF cpumap allocations, from Jason Wang.
5) Fix potential deadlocks in netfilter getsockopt() code paths, from
Paolo Abeni.
6) Netfilter stackpointer size checks really are needed to validate
user input, from Florian Westphal.
7) Missing timer init in x_tables, from Paolo Abeni.
8) Don't use WQ_MEM_RECLAIM in mac80211 hwsim, from Johannes Berg.
9) When an ibmvnic device is brought down then back up again, it can be
sent queue entries from a previous session, handle this properly
instead of crashing. From Thomas Falcon.
10) Fix TCP checksum on LRO buffers in mlx5e, from Gal Pressman.
11) When we are dumping filters in cls_api, the output SKB is empty, and
the filter we are dumping is too large for the space in the SKB, we
should return -EMSGSIZE like other netlink dump operations do.
Otherwise userland has no signal that is needs to increase the size
of its read buffer. From Roman Kapl.
12) Several XDP fixes for virtio_net, from Jesper Dangaard Brouer.
13) Module refcount leak in netlink when a dump start fails, from Jason
Donenfeld.
14) Handle sub-optimal GSO sizes better in TCP BBR congestion control,
from Eric Dumazet.
15) Releasing bpf per-cpu arraymaps can take a long time, add a
condtional scheduling point. From Eric Dumazet.
16) Implement retpolines for tail calls in x64 and arm64 bpf JITs. From
Daniel Borkmann.
17) Fix page leak in gianfar driver, from Andy Spencer.
18) Missed clearing of estimator scratch buffer, from Eric Dumazet.
