Re: A system for rebootless kernel security updates

I just wanted to test on my Gentoo system with kernel 2.6.25. The tarball creation works, but applying the change brings an error to syslog

Sorry. (In 2.6.25, init_mm is marked as an unused symbol, and so whether it is exported depends on whether CONFIG_UNUSED_SYMBOLS is enabled).

I've committed a change which should fix this problem. You can get get the new version (0.8.1) from http://web.mit.edu/ksplice/dist/ or from Git. (I haven't yet made the new version the default, so you won't receive it from the main Ksplice page).

This sounds really interesting. I just wanted to test on my Gentoo system with
kernel 2.6.25. The tarball creation works, but applying the change brings an
error to syslog:

ksplice_242e9pfc_helper: Unknown symbol init_mm

Any chance to get a fix for that?
