I'm not sure why >2.1.2.2 would behave differently since there haven't been any changes in the way that the postinst phase if spawned. The code path for that phase is the same whether you're running selinux or not since postinst runs with sesandox disabled. I had segfaults under Portage too. I think that was after upgrading glibc etc and was solved by booting the machine. The server in question was not running selinux but it was running hardened kernel etc. I don't think this has anything to do with portage. Please reopen if you have more info. I do not know what more info you need than from portage 2.1.2.2 emerge -1 =portage-2.1.2.7 && emerge -1 selinux-base-policy and you got the segfault, emerge -1 portage-2.1.2.2 && emerge -1 selinux-base-policy and everything works again. I do not know *at all* what changed, but something must have changed that directly or indirect handles selinux!

That code is only triggered for the fetch phase though, so it doesn't seem like it could have anything to do with a segfault during postinst. If it's really related to something that portage is doing then you'll have to provide more information about why the segfault is happening and what portage can do to prevent it. You might also try portage-2.1.2.11 or portage-2.1.3.1 to see if those make any difference. *** Bug 187468 has been marked as a duplicate of this bug. *** I had exactly the same problem. But for me it workls with portage-2.1.3.1. Thanks! portage-2.1.2.11 does not work, portage-2.1.3 works. I'm still clueless on this one. Anyway, I glad to hear that 2.1.3 seems to work. If anybody has any idea what change may have triggered this then please comment. I do not know, but it was one of the changes between 2.1.2.2 and 2.1.2.3 (I tried the "dead" ebuild from portage cvs). There are some changes picked up by portage -d in the output (exept for postinst where the only diff is the errormessage), and after some ugly testing I am pretty sure that it is before the postinst portage made something not so good. From portage-2.1.2.2 do a 'ebuild selinux-base-policy install' and from portage-2.1.2.3 doing the merge and postinst did not produce the errors as far as I could see. However I have not and therefore will not spend more time on the issue. If it comes back in newer version I may. |
