[PATCH] mount: segmentation faults on UDP mounts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This came in over the weekend... when a server only supports 
UDP mounts, mount seg faults... this patch fixes the problem...

steved.

commit 52ec1b5fceece8f63b97afc6d6b78bfabff12669
Author: Steve Dickson <steved@xxxxxxxxxx>
Date:   Tue Feb 17 15:33:58 2009 -0500

    The mount sockaddr len (mnt_salen) is not be set in
    nfs_extract_server_addresses() which causes the mount.nfs
    command to segmentation fault when a NFS server only
    supports UDP mounts.
