Subject: [PATCH 0/5] Fix assorted errors in the Qemu socket tap receive handler
Date: Fri, 26 Jul 2024 17:20:26 +1000	[thread overview]
Message-ID: <20240726072031.3941305-1-david@gibson.dropbear.id.au> (raw)

A long time ago Matej Hrica pointed out a possible buffer overrun when
receiving data from the qemu socket.  Stefano recently proposed a fix
for this, but I don't think it's quite right.  This series is a
different approach to fixing that problem and a few adjacent ones.

David Gibson (5):
  tap: Better report errors receiving from QEMU socket
  tap: Don't attempt to carry on if we get a bad frame length from qemu
  tap: Don't use EPOLLET on Qemu sockets
  tap: Correctly handle frames of odd length
  tap: Improve handling of partially received frames on qemu socket
