Bug 250301 – linux-mod.eclass: kernel sources accessed through /lib/modules/`uname -r`

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

[Description Diego Elio Pettenò (RETIRED) 2008-12-08 16:32:42 UTC]

This bug is being reported because this ebuild is currently trying to build against the kernel tree by accessing it through /lib/modules/`uname -r` instead than through /usr/src/linux like it should.

This is bad in many situations, like:

- livecd installs: the running kernel is the one from the livecd and is most
likely not the same the user is installing to;
- livecd chroot fixes: as above;
- generic chroot: running kernel comes from outside, as above;
- kernel updates: users most likely would want their system to have all the
modules ready _before_ restarting.

Please fix your ebuild to use /usr/src/linux.

Thanks,
Diego

All this logic seems to be handled by the linux-mod and linux-info eclasses.

The ebuild doesn't actually do anything besides calling eclass functions.

Thanks

workaround

This is a patch against the ebuild to show what is wrong.

Unless you have the param KDIR set the ${S}/module/Makefile then does by default the faulty behaviour that this bugreport is about.

This patch is wrong in so many ways, only a proof of concept. But I do not think KDIR is one of the "standard" variables, and thus it falls on the ebuild to set it.

>=sysprof-1.1 does not install a kernel module, so sysprof is no longer connected with this bug.

Diego, is this bug report is still relevant with the current state of the linux-info.eclass?

any news for this bug ?

[Comment 9 Mike Pagano 2018-07-23 15:59:32 UTC]

I don't see any call to uname in linux-mod.eclass . If I'm missing anything here, please re-open.
