Description of problem:
/sbin/mount.cifs //WIN98/DATA$ /mnt/mount_samba/ -o servernetbiosname=WIN98,nocase,noserverino

worked fine using kernel-2.6.35.12-88, now fails using kernel-2.6.35.13-91 with mount error(22): Invalid argument.

How reproducible:
Always reproducible


Steps to Reproduce:
/sbin/mount.cifs //WIN98/DATA$ /mnt/mount_samba/ -o servernetbiosname=WIN98,nocase,noserverino

  
Actual results:

What does the corresponding trace look like when it works in the older kernel?

Comment 3 Hans Ecke 2011-05-13 17:57:25 UTC 
Same symptoms here. 2.6.35.12-90.fc14.i686 works fine, while 2.6.35.13-91.fc14.i686 produces the error. Happy to provide additional debug output, but surface symptoms are identical to Sandro's.

My mount command line:

mount -t cifs -o domain=mesoscopic,sec=lanman,servern=ABMM,password=,file_mode=0644,dir_mode=0755 //10.11.12.13/VNA_MS98_D /mnt/abmm_d
Comment 4 Chuck Ebbert 2011-05-16 14:02:44 UTC 
Only one cifs patch went in 2.6.35.13:

Yes, the patch seems to fix the issue for me. The share seems to be mounted correctly, without any error message.
Comment 7 Jeff Layton 2011-05-17 10:51:59 UTC 
Patch sent upstream and I cc'ed stable. It should make the stable series in the near future.
Comment 8 Sandro Bonazzola 2011-05-17 11:26:18 UTC 
Thanks
Comment 9 Sandro Bonazzola 2011-05-17 13:35:48 UTC 
Win98 PC died with a blue screen of death on TCPIP.
On linux side the mount command said:

It seems it doesn't work very well after all.
Comment 10 Jeff Layton 2011-05-17 13:43:52 UTC 
This patch should fix the original problem. If Win98 is crashing, then there's not much we can do about it unless you can diagnose what's causing it.

I'll do more testing tomorrow in order to ensure it's a win98 problem and nothing related to the original problem.
Comment 12 Sandro Bonazzola 2011-05-18 07:39:25 UTC 
I can confirm it's a win98 problem and nothing related to the original problem. The patch works fine. 
Could you please add the patch to f14 stable kernel while we are waiting for a new upstream kernel stable release?
Comment 13 Chuck Ebbert 2011-05-18 17:58:40 UTC 
The fix will be in 2.6.35.13-92
