Description Matt Seitz 2004-01-25 08:11:35 UTC
When nmbd is loaded it will report an error if the netbios name is 15 characters
long. The problem appears to be in the send_announcement function in
src/ext/samba/source/nmbd/nmbd_sendannounce.c.  Line 106 reads:
    push_string(NULL, p+5, server_name, 15, STR_ASCII|STR_UPPER|STR_TERMINATE);

The STR_TERMINATE flag adds one to the server_name length, making it greater
than maximum destination length of 15.

I am using Samba 3.0.0rc1, but I checked the latest revisions on cvsweb.  They
appear to have the same problem.

I am attaching the "conf" file I use when I see the error.  Here is the error

nmbd -i -s seitz2003s2.conf
Netbios nameserver version 3.0.0rc1 started.

standard input is not a socket, assuming -D option
convert_string: Required 16, available 15
Comment 2 Matt Seitz 2004-02-06 08:27:21 UTC
The error message does not appear in the 3.0.2rc2 version of nmbd, because the
behavior of convert_string has changed.  If all of the following are true, then
the 3.0.2rc2 version of convert_string will not print an error message when the
source string is longer than the maximum destination length:
1.  The source format is not UCS2.
2.  The destination format is not UCS2
3.  The source string is all ASCII 

I would like to change this bug's resolution to "fixed", but Bugzilla says I
don't have permission to change the status field.

Matt says fixed.

originally reported against one of the 3.0.0rc[1-4] releases.
Cleaning up non-production versions.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
