wpaul 95/03/26 15:36:39 Modified: sbin/mountd mountd.c Log: Fixed stupid bug in mountd: it would seem that the kernel doesn't allow you to push the same host into its NFS export lists twice, but mountd tries to do it anyway. This means that putting: /some_file_system -ro host1 host1 in your /etc/exports file causes an error. This is bogus: mountd should be smart enough to ignore the second instance of host1. This can be a problem in some configurations that use netgroups. For example, each host in my netgroups database is has two entries: startide (startide,-,) (startide.ctr.columbia.edu,-,) When mountd sees this, it tries to put startide.ctr.columbia.edu into the export list *twice*. Just listing 'startide' /etc/exports list will also screw up because mountd will try to resolve the netgroup 'startide' instead of the hostname 'startide.' My solution is watch for duplicate entries in get_host() and mark them as grouptype GT_IGNORE, which do_mount() will now cheefully throw away. This is a bit of a kludge, but it was the least obtrusive fix I could come up with. Also silenced a compiler warning: arguments passwd to xdr_long() should be u_long, not int. :)
