Merge branch 'bpf_sk_storage_via_inet_diag'
Martin KaFai Lau says:
====================
The bpf_prog can store specific info to a sk by using bpf_sk_storage.
In other words, a sk can be extended by a bpf_prog.
This series is to support providing bpf_sk_storage data during inet_diag's
dump. The primary target is the usage like iproute2's "ss".
The first two patches are refactoring works in inet_diag to make
adding bpf_sk_storage support easier. The next two patches do
the actual work.
Please see individual patch for details.
v2:
- Add commit message for u16 to u32 change in min_dump_alloc in Patch 4 (Song)
- Add comment to explain the !skb->len check in __inet_diag_dump in Patch 4.
- Do the map->map_type check earlier in Patch 3 for readability.
