This series enables BPF programs to fetch sockets from SOCKMAP/SOCKHASH by doing a map lookup, as proposed during virtual BPF conference. Patch 1 description covers changes on verifier side needed to make it work. Fetched socket can be inspected or passed to helpers such as bpf_sk_assign, which is demonstrated by the test updated in patch 3.

Applied, thanks!
