Subject: [PATCH net v2 0/3] xen-netback: fix rx slot estimation
Date: Thu, 27 Mar 2014 12:56:10 +0000 [thread overview]
Message-ID: <1395924973-42904-1-git-send-email-paul.durrant@citrix.com> (raw)
Sander Eikelenboom reported an issue with ring overflow in netback in
3.14-rc3. This turns outo be be because of a bug in the ring slot estimation
code. This patch series fixes the slot estimation, fixes the BUG_ON() that
was supposed to catch the issue that Sander ran into and also makes a small
fix to start_new_rx_buffer().
v2:
- Added BUG_ON() to patch #1
- Added more explanation to patch #3
