2c08ac2b38 - do validation check and IPv4-mapped IPv6 address handling before
any query.
- don't query against IPv6 link-local address.
- use IN6_IS_ADDR_V4{MAPPED,COMPAT} macros.
- use memcpy() instead of bcopy().

1cc11684ac MFdragonfly: resolver fix for timeouts on unqualified hostnames
res_search only incremented got_servfail for h_errno == TRY_AGAIN *AND*
  hp->rcode == SERVFAIL.  However, there are cases such as timeouts where
  rcode is not always set to SERVFAIL.  This leads to inconsistent nameserver
  operation during multi-domain and truncated dot searches, especially during
  booting when portions of the network are being brought up simultanious with
  dns lookups.

  This patch attempts to correct the problem by unconditionally terminating
  the search if TRY_AGAIN is returned (after res_query has gone through all
  retries and name servers) instead of trying other domain elements in the
  domain seach path.

  This patch should fix reported problems (which I can reproduce) with some
  NFS mounts failing during boot.  This occured because mount_nfs thought the
  host name lookup returned a definitive failure using a non-dotted host name
  when, in fact, it timed out on the first part (host.search.domain.name) and
  got a definitive host-not-found response on the second part (host.).

  Generally speaking, search path name server timeouts can exceed 60 seconds
  per element and most machines which consistently timeout on earlier portions
  of a search path are effectively non-operational due to the imposed delays.
  It is more important for DNS lookups to return the proper error code then
  to be able to recover a valid lookup in later portions of the search path
  in these situations.

8074e24dce 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.

a03fd3b656 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.

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a

33dee81933 Make the resolver(3) and many associated interfaces much more reentrant.
The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now
with what should be totally reentrant, and h_errno values will now
be preserved correctly, but this does not affect interfaces such as
gethostbyname(3) which are still mostly non-reentrant.

In all of these relevant functions, the thread-safety has been pushed
down as far as it seems possible right now.  This means that operations
that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected
still under global locks that getaddrinfo(3) defines, but where possible
the locking is greatly reduced.  The most noticeable improvement is
that multiple DNS lookups can now be run at the same time, and this
shows major improvement in performance of DNS-lookup threaded programs,
and solves the "Mozilla tab serialization" problem.

No single-threaded applications need to be recompiled.  Multi-threaded
applications that reference "_res" to change resolver(3) options will
need to be recompiled, and ones which reference "h_errno" will also
if they desire the correct h_errno values.  If the applications already
understood that _res and h_errno were not thread-safe and had their own
locking, they will see no performance improvement but will not
actually break in any way.

Please note that when NSS modules are used, or when nsdispatch(3)
defaults to adding any lookups of its own to the individual libc
_nsdispatch() calls, those MUST be reentrant as well.

notices (correct).

c849849d06 It was reported that when using nss_ldap, getgrent(3) would behave
incorrectly when encountering `large' groups (many members and/or many
long member names).  The reporter tracked this down to the glibc NSS
module compatibility code (nss_compat.c): it would prematurely record
that a NSS module was finished iterating through its database in some
cases.

Two aspects are corrected:

1. nss_compat.c recorded that a NSS module was finished iterating
   whenever the module reported something other than SUCCESS.  The
   correct logic is to continue iteration when the module reports
   either SUCCESS or RETURN.  The __nss_compat_getgrent_r and
   __nss_compat_getpwent_r routines are updated to reflect this.

2. An internal helper macro __nss_compat_result is used to map glibc
   NSS status codes to BSD NSS status codes (e.g. NSS_STATUS_SUCCESS ->
   NS_SUCCESS).  It provided the obvious mapping.

   When a NSS routine is called with a too-small buffer, the
   convention in the BSD NSS code is to report RETURN.  (This is used
   to implement reentrant APIs such as getpwnam_r(3).)  However, the
   convention in glibc for this case is to set errno = ERANGE and
   overload TRYAGAIN.  __nss_compat_result is updated to handle this
   case.
