Could someone give me a pointer on a kernel update please ?
We have installed SLES 10 SP3, 64 bit (6 core CPU). The customer is
requesting we install kernel patch 7568 due to security improvements.
(Kernel is ‘here’
a) Is that patch definitely OK for 64 bit ? It mentions i586/x86 only,
no mention of x86_64.
b) Am I right in thinking I need to install only the one rpm, the smp
kernel “kernel-smp-220.127.116.11-0.79.1.i586.rpm” ? Output from uname is
Kernel 18.104.22.168-0.54.5-smp. So I don’t want the default kernel ? Or
any of the other rpm’s available under that patch ?
Thanks for your help in avoiding any midnight disasters.
Does the customer not have an update subscription for this SLES server?
That is the recommended way to get the fixes on the server (using YOU,
the YaST Online Update tool or rug).
Also, the rpm’s you are pointing to are for 32bit systems (hence the
i568 in the name indicating 32bit arch, 64bit is indicated by x86_64).
An added consideration is that along with the kernel there are also
modules and sources that need to match the running kernel. So there
could be bits that brake if you only patch this bit but don’t also
update other packages. Normally the packaging mechanism will warn
against updating a package that might brake others, but that only takes
packages in account that have been added as rpm package, an not those
pieces that have been manually added/compiled.
In all this, my advise would be to update using the YOU tool and via
the official SLES update channel. It should contain the fix in patch
7568 plus more that have been included there after (as this particular
patch was released on 2011-06-29).
Hope that helps,
