Re: [PATCH v2] tcp: relookup sock for RST+ACK packets handled by obsolete req sock

Hello:

This patch was applied to netdev/net.git (refs/heads/master):

On Mon, 15 Mar 2021 14:05:45 +0300 you wrote:

Currently tcp_check_req can be called with obsolete req socket for which big
socket have been already created (because of CPU race or early demux
assigning req socket to multiple packets in gro batch).

Commit e0f9759f530bf789e984 ("tcp: try to keep packet if SYN_RCV race
is lost") added retry in case when tcp_check_req is called for PSH|ACK packet.
But if client sends RST+ACK immediatly after connection being
established (it is performing healthcheck, for example) retry does not
occur. In that case tcp_check_req tries to close req socket,
leaving big socket active.
