Description Alexandru N. Barloiu 2003-10-31 02:22:05 UTC

Using the same .config, make mrproper, menuconfig, dep, bzImage, modules with 
kernel 2.4.22-xfs I noticed that if i try to create a directory from anywhere 
( like bash/perl/phyton/whatever ) fails with file exists ... althou it created 
the directory. The old 2.4.20-xfs-r3 doesn't do that. Also tar xf with pipes 
loads 99% of cpu and can't create directorys. ( emerge like unarch ) 

Reproducible: Always
Steps to Reproduce:
1.Emerge xfs-sources-2.4.22-xfs 
Actual Results:  
1. mkdir fails 

Expected Results:  
1. should not fail

Comment 1 Rumi Szabolcs 2003-11-05 23:18:58 UTC

I have also hit the very same problem. "File exists" errors everywhere,
directories exist when they should not be and this breaks all Makefiles,
emerges, everything. There is also a severe slowdown when doing an
'emerge sync' for example. When doing xfs_check against a filesystem
previously hit by this, it does not show any corruption.

I have tested the following kernels:

gentoo xfs-sources-2.4.22                affected
gentoo xfs-sources-2.4.20-r3             not affected
vanilla 2.4.21 + xfs release 1.3.1       not affected
sgi xfs-cvs from 2003.11.04 (2.4.22)     not affected

I hope this helps to narrow it down.

Do you ahve grsecurity enable, and could you forward 
your .config to livewire@gentoo.org

Comment 4 Andrea Luzzardi 2004-01-07 10:26:19 UTC

Fixed on xfs-sources-2.4.23-r1

Comment 5 Paul Slinski 2004-02-13 10:46:31 UTC

This appears to be an issue with xfs-2.4.24-r1 now.
