I'm using rsnapshot (from pkgsrc) to do rsync backups (to a netbsd 
machine) of files on a Windows XP box, mounted on the netbsd machine via 
smbfs.  When I first started doing this, I kept getting "Bad file 
descriptor" errors for certain directories, and eventually tracked down 
this: 
http://lists.samba.org/archive/samba-technical/2005-November/043823.html.  
I contacted the person who posted that message (as shown below) and they 
replied with a patch to smbfs_smb.c that fixes the problem, and a link 
to: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/78953 which 
describes the problem (and the fix) in detail. 

I've applied the patch to my machine and it fixes my problem.  My 
question is: how do I get this patch integrated into NetBSD? 

Thanks,

Nathan

Hi Nathan,

Yes, I was able to finally trace the problem down and posted a path (plus
full description of the problem) to the FreeBSD PR system

http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/78953

Bottom line, apply this patch against smbfs_smb.c

I hope this helps.
