* Make the __dns_getanswer() wrapper work right. For the newer versionswpaul1996-12-241-1/+14
| | | | | | | of BIND, we need to tweak some things to that gethostanswer() knows whether or not we're dealing with an IPv4 or IPv6 address. (This'll teach me to use a 2.1.0 system for NIS development -- but it's so nice and stable I just can't being myself to upgrade it. :)

* Fix for bug noticed by Christoph Kukulies.wpaul1996-12-201-2/+3
| | | | | | | | | | | | | | | | _yp_dobind() checks to see if a fork() happens (by checking PIDs) and invalidates all bindings if it finds itself in a newly created child process. (This avoids sharing RPC client handles and socket descriptors with the parent, which would be bad.) Unfortunately, it summarily calls clnt_destroy() on the handles, which may result in the destruction of a descriptor that isn't really a socket. This is fixed by replacing the explicit call to clnt_destroy() with a call to _yp_unbind(), which deals with potentially hosed socket descriptors an a safe manner. This is basically a one-liner. Once I confirm that it fixes Christoph's problem, I'd like permission to put it in the 2.2-RELENG branch.

| | | | | | | | | | | | | | and he said: The 3rd agrument is new; looks like it was part of the upgrade to a new BIND with some IPv6 support. The third argument here should be AF_INET. In order for it to be anything else, I'd have to add new NIS functions to support IPv6 lookups. I don't even know what those look like yet. So there ya go, add AF_INET as the 3rd argument to the call. Submitted-by: wpaul

* Add support for detecting and hopefully using the passwd.adjunct.bynamewpaul1996-12-031-13/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | NIS map which is present on SunOS NIS servers with the SunOS C2 security hack^Woption installed. I'm convinced that the C2 security option restricts access to the passwd.adjunct.byname map in the same way that I restrict access to the master.passwd.{byname,buid} maps (checking for reserved ports), which means that we should be able to handle passwd.adjunct.byname map correctly. If _havemaster() doesn't find a master.passwd.byname map, it will now test for a passwd.adjunct.byname map before defaulting back to the standard non-shadowed passwd.{byname,byuid} maps. If _pw_breakout_yp() sees that the adjunct map was found and the password from the standard maps starts with ##, it will try to grab the correct password field from the adjunct map. As with the master.passwd maps, this only happens if the caller is root, so the shadowing feature is preserved; non-root users just get back ##username as the encrypted password. Note that all we do is grab the second field from the passwd.adjunct.byname entry, which is designated to be the real encrypted password. There are other auditing fields in the entry but they aren't of much use to us. Also switched back to using yp_order() to probe for the maps (instead of yp_first()). The original problem with yp_order() was that it barfed with NIS+ servers in YP compat mode since they don't support the YPPROC_ORDER procedure. This condition is handled a bit more gracefully in yplib now: we can detect the error and just punt on the probing.

Old code assumes success if some of LC_ALL subset is successed even other fails, POSIX treats it as failure with previous locale restoring, fix it.
