Merge branch 'soreuseport-fix-broken-so_incoming_cpu'
Kuniyuki Iwashima says:
====================
soreuseport: Fix broken SO_INCOMING_CPU.
setsockopt(SO_INCOMING_CPU) for UDP/TCP is broken since 4.5/4.6 due to
these commits:
* e32ea7e74727 ("soreuseport: fast reuseport UDP socket selection")
* c125e80b8868 ("soreuseport: fast reuseport TCP socket selection")
These commits introduced the O(1) socket selection algorithm and removed
O(n) iteration over the list, but it ignores the score calculated by
compute_score(). As a result, it caused two misbehaviours:
* Unconnected sockets receive packets sent to connected sockets
* SO_INCOMING_CPU does not work
The former is fixed by commit acdcecc61285 ("udp: correct reuseport
selection with connected sockets"). This series fixes the latter and
adds some tests for SO_INCOMING_CPU.
