due to the semantics of btrfs_search_slot the path can point to an
invalid slot when ret > 0. This condition went unnoticed, which in
turn could have led to an incomplete scrubbing.

I see the same warnings with Debian's gcc-4.6 (here: next-20110603),
plus some more:

Hi,
If no one is already working on it, I'd like to take the Quota lock and
see how far I come.
Let me sketch out in short what I'm planning to do:
- Quota will be subvolume based. Only the FS-trees and data extents
will be accounted.
- Quota Groups can be defined. Every quota group can com

btrfs overwrites memory for too long device paramater
try
btrfs device scan $(awk 'BEGIN{$5090=OFS="x";print}')
...
** buffer overflow detected ***: btrfs terminated
=== Backtrace: =
/lib64/libc.so.6(__fortify_fail+0x37)[0x7f0ef2ea0607]
/lib64/libc.so.6(+0xf6580)[0x7f0ef2e9e580]
btrfs
btrfs_scan_one_device() directly uses vol->name
without additional checks so in the case of unterminated
string in ioctl it can access memory outside
of btrfs_ioctl_vol_args struct.
Always terminate name string (as the same as other users
do already).

Hi,
I'm using SL 6 (RHEL 6) and I've been playing around with running
PostgreSQL on btrfs. Snapshotting works ok, but the computer keeps
rebooting without warning (can be 5 mins or 1.5 hours), finally I
actually managed to get a Kernel Crash instead of just a reboot.
I took a picture of the scree
