Description Thorsten Leemhuis 2007-10-11 13:17:40 EDT
Description of problem:
Kmods need a sane way to get exactly the kernel they were compiled for; that
worked fine in F7 and is broken in rawhide.

E.g in F7 a kmod for the stock kernel had a line like this...
Requires: kernel-i686 = 2.6.21-1.3194.fc7
That dep is provided by the matching kernel package:
$ rpm -qp kernel-2.6.21-1.3194.fc7.i686.rpm --provides
kernel-i686 = 2.6.21-1.3194.fc7

For a PAE is was similar. Kmod had...
Requires: kernel-i686 = 2.6.21-1.3194.fc7PAE
That dep is provided by the matching kernel package:
$ rpm -qp --provides kernel-PAE-2.6.21-1.3194.fc7.i686.rpm 
kernel-i686 = 2.6.21-1.3194.fc7PAE

In rawhide the stock and the PAE kernel provide the same version:

$ rpm -qp kernel-2.6.23-5.fc8.i686.rpm --provides 
kernel-i686 = 2.6.23-5.fc8
$ rpm -qp kernel-PAE-2.6.23-5.fc8.i686.rpm --provides 
kernel-i686 = 2.6.23-5.fc8

That lead to reports from users that a kmod for the stock kernel pulled in the
PAE kernel.

Additional info:
Would be nice to see this fixed before F8 gets shipped as this regression would
create major trouble for 3rd party repos that ship kernel module packages.

Build-testing theoretical fix now...
Comment 2 Jarod Wilson 2007-10-12 12:52:43 EDT
Theoretical fix confirmed as an actual fix, and committed to cvs. Next kernel
build should have fixed-up Provides.
