Bad file descriptors with samba-2.2.x -- more details.

[wolfgang.glas at ev-i.at]

Dear samba team,

  Here is an exact description on how to reproduce the bad file decsriptor 
error using a trivial smb.conf.

My configuration is smaba-2.2.5 under Linux (SuSE-80; kernel 2.4.18)

One host has all filesystems on reiserfs on top of LVM.

The other host is ext3-based with /usr and the root filesystem running 
reiserfs.
(/ext and /home are on ext3)

The smb.conf file follows:
----------------------------------------
# Samba config file created using SWAT
# from localhost (127.0.0.1)
# Date: 2002/06/28 10:19:30

# Global parameters
[global]
        workgroup = abc
        server string = Samba %v on my_host
        encrypt passwords = Yes
        map to guest = Bad Password
        socket options = SO_KEEPALIVE IPTOS_LOWDELAY TCP_NODELAY
        character set = ISO8859-15
        os level = 2
        printing = lprng

[homes]
        comment = Home Directories
        read only = No
        create mask = 0640
        directory mask = 0750
        browseable = No

[printers]
        comment = All Printers
        path = /var/tmp
        create mask = 0600
        printable = Yes
        browseable = No

[incoming]
        comment = Put incoming for me here.
        path = /home/me/incoming
        read only = No
        guest ok = Yes

[testpr]
        comment = Testprinter on ev-i02
        guest ok = Yes
        printable = Yes
        print command = mv %s %U-%s
        lpq command =
        lprm command = 
----------------------------------------

With this configuration file I put a word doc-file into the share 
incoming, open the file using MS word 2000 or XP.
Then I print to printer testpr on the host (using some postscript printer 
setting...)

After printing I change and save the file.

After three or four rounds doing printing, changing, saving either word is 
unable to save the file or the spooling service of Win XP hangs.

On the server, the the bad file descriptor errors occur or contents of the 
log file are appended to the catched print jobs etc...
(Sometime the print job is appended to log.smbd...)

Changing to

lpq command = /bin/echo

solves the problem and everything works fine.

I hope this will help to solve the described bug in samb-2.2.5.

Please feel free to contact me, if some needs mre information on this.

Best regards,
 
  Wolfgang
