b7ac97b866 More agressive assertions. Change a number of detected conditions, which 
officially have undefined behavior, from returning an error code to raising
an assertion failure.
Also, don't bother to explicitly test for (illegal) null pointers and return
an error; they'll bomb out soon enough.

64b72cb09f A couple of READ calls in td_sync_info() were reading into a 
pthread_spin_t variable (4 bytes) but telling read that they were
reading sizeof(struct pthread_spinlock_st) (12 bytes). This led to
overwriting other things on the stack, like the return address. Oops.

Fix by changing READ call here (and elsewhere, for future safety) to:
  READ(,, &variable, sizeof(variable))
instead of
  READ(,, &variable, sizeof(type)).

b5dda3e238 From: "Jason L. Wright" <jason@thought.net> 
The man page for getaddrinfo() and RFC2553 says it should return EAI_NONAME
for the case where hostname != NULL, hostname is not a numeric string and
ai_flags has the AI_NUMERICHOST bit set.  Instead, it returns EAI_NODATA
for this case.  The diff below makes it return EAI_NONAME for this case.

This is why ntpq and ntpdc from ntp-4.1.74 can't resolve hostnames,
but work fine with numeric strings like ::1 or 127.0.0.1.

75e29ba505 some changes around mklocale: 
- clean up cpp directives.
- stop including rune.h from mklocale.
- stop using _BSD_RUNE_T macro.  instead, use int32_t directly in runetype.h.
- move _DEFAULT_INVALID_RUNE to runetype.h.
These were for historical reason on porting rune from FreeBSD,
but it seems that these are no longer reasonable but troublesome
under the current NetBSD build system.
additionally:
- runetype.h -> locale/runetype.h in mklocale, because this might conflict
  to FreeBSD's one.

f60f35f3ab Don't acquire __environ_lock around exec*() calls; nothing requires 
that these calls be thread-safe with respect to the environment, and it
causes serious problems for threaded applications which call vfork() and
exec*() (including indirectly, via popen() or system()).

Acquire and release __environ_lock in the parent in popen() and system() to
play safe and provide the child with a stable environment.

__environ_lock should also have an atfork() handler; still under development.

65ec6ba6e7 Fix lib/20558: 
A dynamically linked program invokes the rtld cleanup routine via
an atexit handler.  This rtld cleanup routine invokes _fini() for
shared libraries, which in-turn invoke __cxa_finalize() with their
DSO handle.  By luck, this happens to work okay for non-threaded
programs, but for a threaded program, this leads to deadlock (sometimes
manifested as an assertion failure, if the program didn't actually
create any threads).

Fixed by teaching __cxa_finalize() that it can be recursively invoked,
adjusting the handler list manipulation accordingly.

16c5a7dd8d Reorganise the getting of grouplists for a user so that Hesiod (and 
potentially other name services) can directly query for a user's
grouplist rather than needing to iterate over the group map.  This
is required for correct operation of Hesiod.

351f7a02f1 looks like nobody ever seriously tried the _REENTRANT version of this 
code (which, uh, seems the default for a fresh build)...  it wasn't
setting up v1 properly (the instruction to set up v1 was after the
return jump, in "reorder" code...  i.e.  after the end of the function).
That would break error returns from 64-bit syscalls (e.g. checks
in dd and who knows what else) to see if input or output are pipes.
It looks like the non-_REENTRANT version was broken (on the nathanw-sa
branch) in rev 1.9.2.1 and fixed in 1.9.2.2, but the _REENTRANT version
was never fixed, and the broken bits were merged back on to the trunk.

69367db47f Do a similar tuneup on pthread_cond_signal() and 
pthread_cond_broadcast(): use double-checked locking to avoid

on a condition variable with no waiters.

6cca91fc86 Mutex tuneup. 
* Use a double-checked locking technique to avoid taking
   the interlock in pthread_mutex_unlock().

 * In pthread_mutex_lock() and pthread_mutex_trylock(), only store the
   stack pointer, not the thread ID, in ptm_owner. Do the translation
   to a thread ID in the slow-lock, errorcheck, and recursive mutex
   cases rather than in the common path.

 * Juggle where pthread__self() is called, to move it out of the fast path.

Overall, this means that neither pthread_self() nor
pthread_spin[un]lock() are used in the course of locking and unlocking
an uncontested mutex. Speeds up the fast path by 40-50%, and
eliminates about 98% of spinlocks used by a couple of large threaded
applications.

(Still a GET_MUTEX_PRIVATE() in the fast path... perhaps the type
should be in the main body of the mutex).

  * Refer to _NSIG, not NSIG.

  * Gut pthread_sigmask(). It was handling a lot of corner cases that
    weren't legal anyway. Handle unblocked signals with a new
    pthread__kill_self() routine (also used by pthread_kill()).

  * Be more consistent with locking around pt_sigacts[].
