CVS commit: [netbsd-5] src/usr.sbin/ypbind

Module Name:    src
Committed By:   bouyer

Modified Files:
        src/usr.sbin/ypbind [netbsd-5]: ypbind.c

Log Message:
Pull up following revision(s) (requested by chuck in ticket #1549):
        usr.sbin/ypbind/ypbind.c: revision 1.58 - 1.61
in the case where ypbind is serving more than one domain (i.e.
not just the yp_get_default_domain() domain), we must remove
any old binding files from /var/yp/binding (BINDINGDIR) from
previous runs, or the non-yp_get_default_domain()'s will not
bind properly.   add a purge_bindingdir() function that basically
does "rm BINDINGDIR/*.[0-9]" at ypbind startup time.
example case of where this is an issue: bind a second (non-default)
domain.   ypbind will create and flock a /var/yp/binding/xxx.2
file for it.  stop and restart ypbind.  the old /var/yp/binding/xxx.2
file will remain from the previous run.   since it is not flock()'d
by the new instance of ypbind, libc functions like yp_master() will
fail without even bothering to talk to ypbind itself.   (and ypbind
is totally unaware of the old file...)
