---+ Kernel Updates A sketch of how Birmingham has dealt with the Kernel Security incident. Based on [[http://freshmeat.net/articles/red-hat-updated-kernel-packages-fix-two-security-issues-4][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* | | 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. | Confirmed :-) | | Submit test job | ATLAS job should complete sucessfully. | Confirmed :-) | 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. Grub entries were missing for =kernel-2.6.9-89.0.9=, so they were added manually. Reboot appeared to work. ---++ Full Deployment Rolled out to all Grid resources. =epgd06= did not reboot. =epgse1= and =sr1= booted into the old version. Fixed by another reboot (manual in the case of =epgd06=). -- Main.ChristopherCurtis - 27 Aug 2009
