Subject: [PATCH 0/2] More nritems range checking
Date: Fri,  2 Jun 2017 12:08:12 +0200	[thread overview]
Message-ID: <cover.1496397503.git.hahn@univention.de> (raw)
In-Reply-To: <20170529181900.GV14523@twin.jikos.cz>

Hi,

thank you for applying my last patch, but regarding my corrputed file system I
found two other cases were btrfs crashes:
- btrfs_del_items() was overlooked by me
- deleting from an empty node

Find attached two patches to improve that.
Please check the second patch hunk 2, as I'm unsure if "mid == nritems" is valid.

(If someone can give me a hand on how to get my FS fixed again, I would
appreciate that.)

Philipp Hahn (2):
  btrfs-progs: Check slot + nr >= nritems overflow
  btrfs-progs: Check nritems under-/overflow
