This regression was introduced by execshield change: * Mon Jan 19 2009 Kyle McMartin <kyle> - execshield fixes: should no longer generate spurious handled GPFs, fixes randomization of executables. also some clean ups. This may be caused by the fix for bug 473254. Uh? Execshield is i386 only... I'm curious how this could be breaking on x86_64? Created attachment 334715 [details]
The diff between working and non-working kernels
Here is the diff between working and non-working kernels.
Is there anything which doesn't belong to x86-64 kernel?
My guess is the shlib randomization bits of execshield are horking up glibc... Those /would/ get applied on x86_64... I'm doing a build commenting those out now, and I'll post the URL when they're ready. cheers, Kyle Build is here: http://koji.fedoraproject.org/koji/taskinfo?taskID=1235716 Hopefully it will succeed... It will at least narrow the failure down. I applied this patch:

and kernel works fine on Linux/x86-64. Since arch_get_unmapped_exec_area
only works for 32bit address space, I don't think arch_pick_mmap_layout in
arch/x86/mm/mmap.c should do
mm->get_unmapped_exec_area = arch_get_unmapped_exec_area;
for 64bit processes. It should fix the problem and shorten 64bit programs
load time.
Yeah, I agree, I'll take a closer look at the changes. The build I posted above has the assignment stubbed out on x86_64, so it should resolve the issue as well. Created attachment 334733 [details]
A patch
I am testing this patch against kernel-2_6_27_19-170_2_44_fc10.
(In reply to comment #13) > Created an attachment (id=334733) [details] > A patch > > I am testing this patch against kernel-2_6_27_19-170_2_44_fc10. This patch works for me. kernel-2.6.27.19-78.2.31.fc9.x86_64 has the same bug. My patch for Fedora 10 kernel works on Fedora 9 kernel. This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
