Kernel Updates
A sketch of how Birmingham has dealt with the Kernel Security incident. Based on
this article, it looks like kernel-2.6.9-89.0.9 contains the relevant fixes.
WN test
Tested update on epgd01.
uname -a
returns a kernel version of
2.6.9-78.0.13.ELsmp
.
Test plan:
Step |
Expectation |
Result |
Submit test job |
ATLAS job should complete sucessfully. |
Update kernel using yum |
kernel-2.6.9-89.0.9.EL.i686 should be installed. |
Confirmed |
Reboot |
Should come back up using new kernel. |
Reboot was initially unsuccessful for epgd01. Updated kernel did not appear in the grub menu, and returning to
2.6.9-78.0.13
caused a kernel panic as
/
fs label had changed. This was fixed by guess work - edited grub menu entry for
kernel /vmlinuz-2.6.9-78.0.13.EL ro root=LABEL=/1
, replacing
LABEL=/1
with
LABEL=/
. This at least allowed the system to boot.
