X-Git-Tag: v2.6-dev1~76
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=683b5fc7b86567a32c3b29543813daadfb0c023f;p=thirdparty%2Fhaproxy.git

MEDIUM: quic: flag listener for local accept

QUIC connections are distributed accross threads by xprt-quic according
to their CIDs. As such disable the thread selection in listener_accept
for QUIC listeners.

This prevents connection from migrating to another threads after its
allocation which can results in unexpected side-effects.
