Description Esben Nielsen 2005-04-13 04:52:33 UTC 
Distribution: Fedora Core 2 and 3
Hardware Environment:Pentium III (Coppermine)
Software Environment:
Problem Description:

I mount a windows share from a WinXP labtop. I edit files on it with Emacs.
Once in a while emacs hangs when I try to save a file. If I am not fast enough
to kill emacs the whole machine goes dead. Machine becomes slower and slower
really fast. Soon after emacs starts to hang I can't interact with the machine
at all.

Steps to reproduce:
Mount the share. Open and save files with emacs.

Can you please try with the CIFS client?
Comment 2 Esben Nielsen 2005-04-18 05:38:32 UTC 
Tried with cifs instead of smbfs but I keep getting permissions denied. I have
enabled NTLMv2 in /proc/fs/cifs.
Comment 3 Adrian Bunk 2006-03-03 08:28:16 UTC 
AFAIR you need the latest CIFS code (IOW: 2.6.16-rc5-mm2) for working NTLMv2
support.

Since there's unfortunately noone maintaining the obsolete smbfs code, the most
promising way for you seems to be getting a recent CIFS working.
Comment 4 Steve French 2006-03-03 22:37:34 UTC 
NTLMv2 support is not quite done in the cifs client (close).  Samba (server and
their client libs - which are unrelated) also recently fixed some smaller
problems with their ntlmv2 support
Comment 5 Diego Calleja 2006-08-05 07:00:57 UTC 
NTLMv2 support is being added to 2.6.18, could you try 2.6.18-rc3?
Comment 6 Steve French 2006-10-27 09:23:13 UTC 
The missing NTLMv2 code (needed for mounts to Windows, but not Samba, which is
somewhat less picky here) - is that which would insert the server domain and
name in the ntlmv2 blob - the only difficulty is that they are variable length.
Comment 7 Steve French 2007-08-30 12:36:48 UTC 
Please confirm if this now works on cifs mounts (now that NTLMv2 support has been working for quite some time, and NTLMv2 signing support is also now working in 2.6.22 and later).
Comment 8 Roland Kletzing 2008-05-12 01:59:32 UTC 
so this is on NEEDINFO for more than 1 1/2 yrs - maybe the mail didn`t reach esben? 
found some email adress recently used on lkml - sent him a personal message since i couldn`t add that to CC list here.
Comment 9 Esben Nielsen 2008-05-16 05:24:10 UTC 
Sorry for this. I must have missed the mail.

And I am not working at the workplace where I had the problem anymore, so I can't help out with more comments.

I think it is best to close the bug - which I don't have permission to do :-(

Sorry for the trouble...

Esben
Comment 10 Roland Kletzing 2008-05-17 15:10:12 UTC 
so, with no debug output and without the system with that problem, keeping this open doesn`t make any sense.
