src-test/lib/libc/net/nsdispatch.c, branch stable/6

The previous commit changed the behavior of nsdispatch() in the

case where an /etc/nsswitch.conf file was present, but could not be opened (e.g. due to permissions). Previously, the open failure condition was suppressed, and the built-in defaults were used. In revision 1.11, however, propagated the open failure causing all nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs including getpwnam and gethostbyname unconditionally failed. This commit restores the previous behavior. Pointy hat: nectar (+1 for obstinance; ache had to use clue bat) Reported by: ache

When a dynamic NSS module is built and linked against a thread

library, it may pull in that thread library at run time. If the process started out single-threaded, this could cause attempts to release locks that do not exist. Guard against this possibility by checking __isthreaded before invoking thread primitives. A similar problem remains if the process is linked against one thread library, but the NSS module is linked against another. This can only be avoided by careful design of the NSS module.

Make this compile with -O2. A proper fix would use a struct to represent

vectors, instead of requiring the caller to keep track of element size and count and pass them in by reference.

Whitespace nits.

may be built into libc (`static NSS modules') or dynamically loaded via dlopen (`dynamic NSS modules'). Modules are loaded/initialized at configuration time (i.e. when nsdispatch is called and nsswitch.conf is read or re-read). = Make the nsdispatch(3) core thread-safe. = New status code for nsdispatch(3) `NS_RETURN', currently used to signal ERANGE-type issues. = syslog(3) problems, don't warn/err/abort. = Try harder to avoid namespace pollution. = Implement some shims to assist in porting NSS modules written for the GNU C Library nsswitch interface.

I believe have made all of libc .c's as consistent as possible.

Remove __P() usage.
