Bug 253440 – [2.6.27 regression] Can't modify file on cifs share

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description stano170 2009-01-02 11:44:13 UTC]

After updating to sys-kernel/gentoo-sources-2.6.27-r7 I don't modify any text file on cifs shares. I can add,rename,delete file but don,t modify in openoffice,kwrite,kedit ... 
Kernel 2.6.26 hasn't any problem

Reproducible: Always

Steps to Reproduce:
1.create samba share on server and create some text file
2.mount samba share using mount.cifs on gentoo-sources-2.6.27-r7 (stable kernel)
3.open the file in openoffice or kwrite, edit and save changes in file
4.read error messages :-)

Please provide the mount info about that share (output from the `mount' command), your `emerge --info' and the permissions listed for the file in question (output from the `stat' command). dmesg output may also be of interest.

OUTPUT MOUNT COMMAND
//192.168.1.1/install on /mnt/I_install type cifs (rw,mand)

permission of the file is now 777

I must use kernel 2.6.26-gentoo-r4 and on this kernel is no problem

PS. I'm from slovakia, my english is bad.

What is the error message?
Does it also occur with a more simplistic edit, e.g. nano or even touch?

Can you reproduce this in gentoo-sources-2.6.28?

[Comment 4 Sergey Ovcharenko 2009-01-06 22:31:17 UTC]

Could you provide some information on the version of samba-server you're connecting to? It can be found in /proc/fs/cifs/DebugData.

[Comment 5 Daniel Drake (RETIRED) 2009-01-20 20:49:23 UTC]

stano, what was the resolution here?
