Subject: [PATCH 0/4] Fixes for EAGAIN/EPOLLIN storm and related issues
Date: Thu, 16 Jan 2025 21:32:46 +0100 [thread overview]
Message-ID: <20250116203250.784496-1-sbrivio@redhat.com> (raw)
Patch 3/4 is similar to the patch I sent recently addressing Lina's
report. The rest is for stuff I found while reproducing that using a
parallel HTTP downloader (aria2c) with different parameters and server
locations.
Stefano Brivio (4):
tcp: Fix ACK sequence getting out of sync on EPOLLOUT wake-up
tcp: Don't subscribe to EPOLLOUT events on STALLED
tcp: Set EPOLLET when when reading from a socket fails with EAGAIN
tcp: Mask EPOLLIN altogether if we're blocked waiting on an ACK from
the guest
