Bug 339765 – sys-apps/attr segfault on file copy during dev-dotnet/xsp merge

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Radoslaw Szkodzinski 2010-10-04 22:05:22 UTC]

Hello,
I've hit a segfault in libattr during dev-dotnet/xsp merge
with portage tmpdir on tmpfs.
Other copies don't cause this segfault, so it is something very specific to this merge. It's 100% reproducible.

The log will be attached in the next comment.

Full backtrace of the issue

[Comment 2 Radoslaw Szkodzinski 2010-10-04 22:40:12 UTC]

Sorry, forgot to mention:
sys-apps/attr-2.4.44 and sys-apps/attr-2.4.43 fail in the same way. The stacktrace is from 2.4.44
Coreutils is version 8.5-r1. Merging coreutils with USE=-xattr works around the bug.

Before you ask, I've checked w/o -fprefetch-loop-arrays and that's not responsible.

[Comment 3 SpanKY 2010-10-06 15:14:19 UTC]

try with a non-hardened kernel.  at least Bug 300166 indicates this was the problem.

[Comment 4 Radoslaw Szkodzinski 2010-10-06 18:45:29 UTC]

2.6.35.7-ck1+ - does that look hardened to you? :)
Unless hardened gcc enabled something there for me...
I did get warnings about missing SSP from this kernel.
Possibly the same problem with SMACK, I have it enabled (and use it for some data).

Might be the same thing as in that bug, SMACK creating some xattrs that make libattr explode. Is there an upstream bug report? Where is coreutils upstream now?
