|
I. Background
|
|
|
|
The ciss driver supports HP Smart Array line of hardware RAID controllers.
|
|
|
|
II. Problem Description
|
|
|
|
There is a programming error discovered in the ciss(4) driver, where a missing
|
|
lock can trigger a failed assertion when the volume state changes, such as
|
|
disk failure or a disk rebuild.
|
|
|
|
III. Impact
|
|
|
|
Systems using the ciss(4) driver may experience system crashes or data
|
|
corruption when the volume state change.
|
|
|
|
IV. Workaround
|
|
|
|
No workaround is available, but systems that do not use ciss(4) devices are
|
|
not affected.
|
|
|
|
V. Solution
|
|
|
|
Perform one of the following:
|
|
|
|
1) Upgrade your system to a supported FreeBSD stable or release / security
|
|
branch (releng) dated after the correction date.
|
|
|
|
2) To update your present system via a source code patch:
|
|
|
|
The following patches have been verified to apply to the applicable
|
|
FreeBSD release branches.
|
|
|
|
a) Download the relevant patch from the location below, and verify the
|
|
detached PGP signature using your PGP utility.
|
|
|
|
# fetch http://security.FreeBSD.org/patches/EN-14:05/ciss.patch
|
|
# fetch http://security.FreeBSD.org/patches/EN-14:05/ciss.patch.asc
|
|
# gpg --verify ciss-10.patch.asc
|
|
|
|
b) Apply the patch.
|
|
|
|
# cd /usr/src
|
|
# patch < /path/to/patch
|
|
|
|
c) Recompile your kernel as described in
|
|
<URL:http://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the
|
|
system.
|
|
|
|
3) To update your system via a binary patch:
|
|
|
|
Systems running a RELEASE version of FreeBSD on the i386 or amd64
|
|
platforms can be updated via the freebsd-update(8) utility:
|
|
|
|
# freebsd-update fetch
|
|
# freebsd-update install
|
|
