per-domain. Also, use the file for the domain we're servicing instead
of always the file for the default domain.
Partly from Wolfgang Stukenbrock's patch in PR 43900.
is used the messages are sent via printf instead of syslog(3).
Also, make sure that none of the calls include a trailing newline and
issue a trailing newline in the -d case so they actually print properly.
(This was noted by Wolfgang Stukenbrock in PR 43900.)
And finally, fix some cases that could in some circumstances print
uninitialized errnos.
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...)
to a 2-clause licence (retaining UCB clauses (1) and (2)), per PR
22409 from Joel Baker, approved by Theo de Raadt, and ratified by
myself - the only discrepancy being the handling of the original
clause 3 in src/usr.sbin/yppoll/yppoll.c.
Remove dom_server_port from struct _dom_binding. It's never initialised
and used in only one place, where dom_server_addr.sin_port was probably
intended.
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that. It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.
Messages will still be printed to stderr if ypbind is started in debug mode.
- Don't exist if none of the servers listed in
/var/yp/binding/<domainname>.ypservers are reacheable. It's a temporary
failure that can be recovered from.
