Kernel Config for 3.3.7-hardened-r1

Description Hongjiu Zhang 2012-06-03 17:57:05 UTC
I am not sure whether I should submit this bug to core system or genkernel.

There is no /usr/include/linux/ext2_fs.h in sys-kernel/linux-headers-3.4, which is required by genkernel to build busybox.

Reproducible: Always

Kernel Config for 3.3.7-hardened-r1
Comment 3 C D 2012-06-08 05:29:53 UTC
I am having what looks like the same problem.
I haven't been able to compile a kernel for over a week.
Not even older kernels that I have already compiled work.

Comment 4 Yan-Fa Li 2012-06-08 05:53:10 UTC
I had this problem. It turns out the version of busybox, 1.9, that genkernel requires is too old to build never 3.* kernels because some of the ext2 headers have been moved. Changing my busybox version to

BUSYBOX_VER="1.20.1"

and copying busybox to genkernel's cache fixed it for me

cp /usr/portage/distfiles/busybox-1.20.1.tar.bz2 /var/cache/genkernel/src/

This would probably fix genkernel too.

Yep, this works and it is the correct solution since its busybox's util-linux that's looking for linux/ext2_fs.h.

@genkernel folks.  Can we accelerate this since everyone using genkernel is going to hit it.  I'd add a blocking depend on linux-headers-3.4 for older versions of genkernel and bump BUSYBOX_VER on the next candidate for stabilization.

Everyone
- on testing,
- without a busybox cache and
- with a beeling edge kernel around, yes.

The current patches of busybox 1.19.3 do not apply against 1.20.1 as is.  Let's see what I can do.

Should be fixed.  Please try 3.4.35 and re-open as needed.
Comment 8 Stéphane BARBARAY 2012-07-03 05:18:49 UTC
kernel 3.3.8 is now amd64 stable, so the problem is now happening on stable amd64 arch...
Even if we could unmask genkernel-3.4.35, this would also require to unmask >=openrc-0.9.9 and so on

A stable genkernel with a stable openrc is now needed for being able to build a stable kernel
Comment 9 Michael Mol 2012-07-03 13:32:30 UTC
I've just synced. Stable sys-kernel/gentoo-sources (3.3.8), stable sys-apps/openrc (0.9.8.4) and stable sys-kernel/genkernel (3.4.24_p1) don't result in a working genkernel build. These are the latest stable versions of each package for amd64, from what eix tells me. (found my way over here from Bug 424759)

Which versions are you using?
Comment 10 Michael Mol 2012-07-03 13:33:00 UTC
Er. Bug 424579.
Comment 11 Rick Farina (Zero_Chaos) gentoo-dev 2012-07-03 18:28:57 UTC
This is actually a significant problem for stable users, 3.4.35 isn't marked stable, the package versions causing this bug are, hence, this is not *resolved* until genkernel 3.4.35 is also marked stable.
Comment 12 swanpoint 2012-07-08 00:09:00 UTC
With BUSYBOX_VER="1.20.1" genkernel gets through a compile of sources 3.3.8 for me. But, on reboot my initramfs can't find my ext2 root under dmraid/mdadmin/lvm. The last 4 kernel versions have been flawless.

if I am not mistaken, the stabilization of 3.4.24_p2 (using busybox 1.20.1) should solve the problem for users of Gentoo stable.  As bug #425360 is dedicated to that now, I dare closing this bug as fixed.(In reply to comment #12)

Please try with genkernel 3.4.36 and report a new bug against it, if the problem persists.
