Description MickKi 2008-01-26 00:03:37 UTC
Since gentoo-sources-2.6.20-r8 I have been unable to emerge kernel modules like:

emerge -Dv media-libs/svgalib sys-fs/fuse x11-base/x11-drm net-wireless/ndiswrapper net-dialup/ltmodem

They all fail with:

==============================================

I noticed the same error with gentoo-sources-2.6.23-r3, but after a while newer module ebuilds came out that would compile and build without errors, at least for some/most of the list of modules shown above (x11-base/x11-drm never managed to emerge).  If this report is not appropriate, please let me know if I need to submit separate bugs for each module.

Reproducible: Always

Steps to Reproduce:
1.module-rebuild rebuild
2.
3.

Uhm... maybe, don't mess with default umask?

Oops!  It seems that I have set up umask as 077 for root:
===========================================
# /etc/skel/.bashrc:
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/skel/.bashrc,v 1.8 2003/02/28 15:45:35 azarah Exp $

# 077 would be more secure, but 022 is generally quite realistic
umask 077
===========================================

The thing is I can't even recall doing this . . . which means that it must be year(s) ago.  I have only started having problems emerging kernel modules with the 2.6.23-rXX series.  Has anything else changed?

Sorry for the noise.

Nah, unless you had KBUILD_OUTPUT set to a directory with more appropriate permissions and now have unset it - and as you noticed in Comment #0, this isn't 2.6.23+ specific for sure :)

Anyway, closing.
