Hello all,

This might be a bit of a silly question but hopefully someone will be kind enough to help.

I've begun to use Gentoo on several SPARCs and I use two as redundant gateways in a production network. They run like a dream.

The only downtime we have is booting for kernel upgrades.

I've read the de facto docs which state you should upgrade immediately if there's a vulnerability announced or otherwise from time to time.

Is there a place I can reliably get mails from or view daily for when a specific kernel version on SPARC is known to have an exploit ?

How often roughly do you think I should upgrade if there aren't security problems ?

Many thanks,

JR :)

I think you can do want you want when there is no threat.

But personnally, if it's for your job do theses upgrades also if there are vulnerability go for a update...not question about that.

Ultimately if everything is working for you and there are no security issues, then I don't see a real reason to upgrade. Also, you'll need to decide for your situation (based on whatever risk policy your place of deployment may use) if a local exploit is worth upgrading for or not.

The kernel source package you are using in Gentoo may help influence your decision as well. Typically sparc-sources (although 2.4 based) is only upgraded for bug fixes or security issues. This also applies to the gentoo-sources 2.6 kernels or the vanilla-sources ebuilds, but those include fixes for all platforms as opposed to just sparc (which makes the volume of version and/or revision bumps higher).

Normally for security announcements, the gentoo-announce mailing list is a good one to subscribe to. Note however that this will have announcements for all packages that have security issues, not just kernel packages.

Thanks for your time, Jason.

That's really appreciated. :)

I'll join the announce list for a while and keep using GLSA too.

Subscribing to the sparclinux maling list would be a nice idea too.
