PROBLEM: Corrupt files with kernel 2.6.0_test11 and smb mounts
From: Daniel Flinkmann
Date: Mon Dec 01 2003 - 05:39:50 EST
Just resending the file, because the subject wasn't correct.
[1.] One line summary of the problem:
2.6.0test11 overwriting file on mounted smb volume causes corrupted files!
[2.] Full description of the problem/report:
When I log into a smb mounted directory and I overwrite a file with
a file which has smaller amount of bytes its corrupting the data.
Easy way to show this is following:
cd onto a smbfs mounted dir.
># echo test1234567890 >test.txt
># cat test.txt
test1234567890
># echo hi! >test.txt
># cat test.txt
hi!
1234567890
>#
As you can see the file is not overwritten as it should be.
[3.] Keywords (i.e., modules, networking, kernel):
2.6test11, smb filesystem
[4.] Kernel version (from /proc/version):
Linux version 2.6.0-test11 (root@tower) (gcc version 3.3.1 (Mandrake Linux
9.2 3.3.1-2mdk)) #1 Sat Nov 29 00:18:20 CET 2003
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
n.a.
[6.] A small shell script or example program which triggers the
problem (if possible)
mounting a smb volume e.g. /mnt/smb type smbfs
># echo test1234567890 >test.txt
># cat test.txt
test1234567890
># echo hi! >test.txt
># cat test.txt
hi!
1234567890
