BUG: TIFF files created by libtiff on NFS4 filesystem are corrupted
Subsystems (2)
Hello!
I have found the following problem with NFS v4 filesystem:
TIFF files written by libtiff are corrupted.
% mount
/home1/ilya/nfs on /home1/nfs4/ilya type none (rw,bind) localhost:/ilya on /home/ilya/nfs type nfs4 (rw,addr=127.0.0.1)
% cd /home1/nfs4/ilya
% tifftopnm 1.tif | pnmtotiff > 1a.tif
% cd /home/ilya/nfs
% tifftopnm 1.tif | pnmtotiff > 1n.tif
% cmp 1.tif 1a.tif
% cmp 1.tif 1n.tif
15315 10 ^H 0 ^@ 15317 10 ^H 0 ^@ 15319 10 ^H 0 ^@
NFS v3 does not have this problem.
Software versions:
Linux 2.6.23.1 #1 SMP Sun Nov 4 01:18:12 MSK 2007 i686 GNU/Linux or
Linux 2.6.23 #1 SMP Fri Oct 12 16:36:16 MSD 2007 x86_64 GNU/Linux
libc6 2.3.6 or 2.6.1 (Debian etch or sid)
libtiff 3.8.2-7 (Debian etch)
netpbm 2:10.0-11 (Debiam etch)
