When using module-init-tools with USE=no-old-linux, emerging some ebuilds create a huge amount of processes, e.g. ppp. This happens at the following point: >>> Original instance of package unmerged safely. * Determining the location of the kernel source code * Found kernel source directory: * /usr/src/linux * Found sources for kernel version: * 2.6.17-hardened-r1 * If the following test report contains a missing kernel configuration option that you need, * you should reconfigure and rebuild your kernel before running pppd. * Checking for suitable kernel configuration options... * CONFIG_PPP_ASYNC: missing asynchronous serial line discipline (optional, but highly recommended) * CONFIG_PPP_SYNC_TTY: missing synchronous serial line discipline (optional; used by 'sync' pppd option) * CONFIG_PPP_DEFLATE: missing Deflate compression (optional, but highly recommended) * CONFIG_PPP_BSDCOMP: missing BSD-Compress compression (optional, but highly recommended) * CONFIG_PPP_MPPE: missing MPPE encryption (optional, mostly used by PPTP links) * Please check to make sure these options are set correctly. * Failure to do so may cause unexpected problems. * Updating /etc/modprobe.conf by hand ...

what files do you guys have in /etc/mod*.d/
(In reply to comment #4) > what files do you guys have in /etc/mod*.d/ In modules.autoload.d: kernel-2.4 + kernel-2.6 In modules.d: aliases + alsa + i386 + nvidia + ppp These are the default files, except for nvidia, where I added the line "options nvidia NVreg_EnableAGPFW=1".

comment http://bugs.gentoo.org/show_bug.cgi?id=142397#c4 lead me to the correct solution. I removed the compatibility entries for nvidia devices in /etc/modules.d/aliases and modules-update works again.
Seems to happen with every external kernel module installation nowadays. I am using sys-apps/baselayout-1.13.0_alpha7-r1 so it might be triggered by that.

I am > using sys-apps/baselayout-1.13.0_alpha7-r1 so it might be triggered by that. > Ok this was just caused by a recent upgrade of nvidia-drivers. Could baselayout be updated so that the entries would only be installed once so that we can at least prevent our users from hitting this problem?
the real fix would be to find out why the thing is fork bombing and stop it from doing so munging drivers isnt a real fix since /etc/modules.d/ is for old things

Created attachment 103671 [details, diff] Fix endless recursion and wrong handling of newline I had analized the problem, and it turns out that these are actually *two* bugs in /sbin/generate-modprobe: 1. If the same alias occurs twice, the grep-commmand in the resolve_alias function returns both matches separated by return. resolve_alias then stumbles over this return due to missing quotes. The clean solution is to die when there are more than one match. 2. There is no test about endless recursion at all in resolve_alias. So the lines alias a b alias b a will also lead to an endless loop. I add a patch which fixes both bugs.
I can confirm that this fixed my forkbombing issue, nice work.

The patch from #12 also fixed this for me.
thanks, fixed in module-init-tools-3.2.2-r2

May I ask that the patch gets backported to -r1? It's a major bug, that the latest 'stable' is suffering from, and adding -r2 to portage.keywords screws things up because it depends on an unstable baselayout, which has other unstable dependancies as well (eg virtual/init)
no
