Subject: [PATCH bpf-next v2 0/2] net: xdp: Two XSKMAP improvements
Date: Wed, 22 May 2019 15:37:40 +0200
Message-ID: <20190522133742.7654-1-bjorn.topel@gmail.com> (raw)

This series add two improvements for the XSKMAP, used by AF_XDP
sockets.

1. Automatic cleanup when an AF_XDP socket goes out of scope. Instead
   of manually cleaning out the "released" state socket from the map,
   this is done automatically. This mimics the SOCKMAP behavior; Each
   socket tracks which maps it resides in, and remove itself from
   those maps at relase.

2. The XSKMAP did not honor the BPF_EXIST/BPF_NOEXIST flag on insert,
   which this patch addresses.


Thanks,
Björn

v1->v2: Fixed deadlock and broken cleanup. (Daniel)
