lib: remove CONSTCOND comment

Since 2021-01-31, lint doesn't need it anymore for the common pattern of
'do ... while (0)'.

libpthread: Move namespacing include to top of .c files.

Stuff like libc's namespace.h, or atomic_op_namespace.h, which does
namespacing tricks like `#define atomic_cas_uint _atomic_cas_uint',
has to go at the top of each .c file.  If it goes in the middle, it
might be too late to affect the declarations, and result in compile
errors.

I tripped over this by including <sys/atomic.h> in mips
<machine/lock.h>.

(Maybe we should create a new pthread_namespace.h file for the
purpose, but this'll do for now.)

- Make pthread_condvar and pthread_mutex work on the stack rather than in
  pthread_t, so there's less chance of bad things happening if someone calls
  (for example) pthread_cond_broadcast() from a signal handler.

- Remove all the deferred waiter handling except for the one case that really
  matters which is transferring waiters from condvar -> mutex on wakeup, and
  do that by splicing the condvar's waiters onto the mutex.

- Remove the mutex waiters bit as it's another complication that's not
  strictly needed.

- Try to eliminate a hang in "parked" I've been seeing while stress testing.
  Centralise wakeup of deferred waiters in pthread__clear_waiters() and use
  throughout libpthread.  Make fewer assumptions.  Be more conservative in
  pthread_mutex when dealing with pending waiters.

- Remove the "hint" argument everywhere since the kernel doesn't use it any
  more.

Enhance the pthread(3) + malloc(3) init model

Separate the pthread_atfork(3) call from pthread_tsd_init()
and move it into a distinct function.

Call inside pthread__init() late TSD initialization route, just after
"pthread_atfork(NULL, NULL, pthread__fork_callback);".

Document that malloc(3) initialization is now controlled again and called
during the first pthread_atfork(3) call.

Remove #if 0 code from pthread_mutex.c as we no longer initialize malloc
prematurely.

G/c unused rwlock owner macros copy-pasted from the kernel.

They were brought along with the rwlock flags but never used and never
even adapted to the new home (the struct member name is different
here).  I looked at adapting and using them, but they don't really
help readability that much and there are cases where we need to deal
with "fused" owner values anyway and so can't use them.

Transfer all the keys that were created in the libc stub implementation
to the pthread tsd implementation when the main thread is created.
This corrects a problem where a process created keys before libpthread
was loaded (either from the libc constructor or because libpthread
was dlopened later). This fixes a problem with jemalloc which creates
keys in the constructor.

libpthread_dbg(3) deletion from the base distribution

libpthread_dbg(3) is a remnant library from the M:N thread model
(pre-NetBSD-5.0) API to introspect threads within a process and for use
of debuggers.

Currently in the 1:1 model it's not used in GDB neither in LLDB and it's
not either planned to be used. It's current function to read pthread_t
structures is realizable within a regular debugger capable to
instrospect objects within a tracee (GDB, LLDB...).

Remaining users of this API can still use this library from
pkgsrc/devel/libpthread_dbg.

libpthread:

Make PTHREAD_KEYS_MAX dynamically adjustable
NetBSD's PTHREAD_KEYS_MAX is set to 256, which is low compared to
other systems like Linux (1024) or MacOS X (512). As a result some
setups tested on Linux will exhibit problems on NetBSD because of
pthread_keys usage beyond the limit. This happens for instance on
Apache with various module loaded, and in this case no particular
developper can be blamed for going beyond the limit, since several
modules from different sources contribute to the problem.
This patch makes the limit conigurable through the PTHREAD_KEYS_MAX
environement variable. If undefined, the default remains unchanged
(256). In any case, the value cannot be lowered below POSIX-mandated
_POSIX_THREAD_KEYS_MAX (128).

While there:
- use EXIT_FAILURE instead of 1 when calling err(3) in libpthread.
- Reset _POSIX_THREAD_KEYS_MAX to POSIX mandated 128, instead of 256.

Fix previous: Can't use calloc/malloc before we complete initialization
of the thread library, because malloc uses pthread_foo_specific, and it will
end up initializing itself incorrectly.

Thanks rump for not letting us use even mmap during initialization.

libc/jemalloc:

Fix non _REENTRANT build.
Defer using pthread keys until we are threaded.
From Christos, fixes PR port-arm/50087 by allowing malloc calls prior
to libpthread initialization.

Allow for arbitrary MI scheduler implementations.

A concrete result is enabling unpatched libpthread to run on the
rumprun stacks (e.g. Xen and bare metal) with a non-NetBSD scheduler.
Those schedulers hook into the existing _lwp_frobnitz() NetBSD syscall
interfaces (well, "syscall" interfaces in that scenario ;)

More specifically about the change itself:

1) instead of calling _lwp_makecontext() followed by _lwp_create()
   and passing the entry point in ucontext_t (MD) through the calls, roll
   the calls into pthread__makelwp() and allow alternate implementations
   for that MI interface.

2) allow compile-time overriding of __lwp_gettcb_fast() or
   __lwp_getprivate_fast, which are inline and leak MD scheduler/thread
   details into libpthread


Additionally, two small nits:

I)  define LIB=pthread before including mk.conf so that it's possible
    to test for LIB==pthread in mk.conf

II) make it possible to leave out pthread_cancelstub.c.  This is required
    by the current implementation of rumprun-posix (i.e. rumprun on
    POSIX hosts) due to symbol collisions.  It needs to be fixed properly
    some day, but for now allows an almost-correct libpthread to run.
    I am sure @justin will be happy to explain the details ;)

Replace the simple implementation of pthread_key_{create,destroy}
and pthread_{g,s}etspecific functions, to one that invalidates
values of keys in other threads when pthread_key_delete() is called.
This fixes chromium, which expects pthread_key_delete() to do
cleanup in all threads.
Don't call the destructor in pthread_key_delete() following the standard.

If TLS support is present, use it for pthread__self(). The
initialisation order is correct in this case as _lwp_setprivate has been
called already by ld.elf_so for dynamic programs or _libc_init for
statically linked ones.

Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Back out using the thread register (if present) for now.

libgcc_s's __register_frame_info gets called from libc's CSU code before
the libc constructors are run. __register_frame_info in turn calls
pthread_mutex_lock. libpthread is not initialised at this point and
therefore pthread__self() traps when deferencing the thread register.
This worked before because the garbage from pthread__self() is
effectively ignored.

Allow storing and receiving the LWP private pointer via ucontext_t
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.

Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.

I've had this patch in my tree for a while and since it only improves
the situation, I decided to commit it. There is an inherent problem
with ASLR and the way the pthread library is using the thread stack.

Our pthread library chooses that stack for each thread strategically
so that it can locate the location of the pthread struct for each
thread by masking the stack pointer and looking just below the red
zone it creates. Unfortunately with ASLR you get many random values
for the initial stack, and there are situations where the masked
stack base ends up below the base of the stack. (this happens on
x86 when the stack base happens to be 0x???02000 for example and
your mask is stackmask is 0xffe00000). To fix this, we detect the
pathological cases (this happens only in the main thread), allocate
more stack, and mprotect it appropriately. Then we stash the main
base and the main struct, so that when we look for the pthread
struct in pthread__id, we can special case the main thread.

Another way to work around the problem is unlimiting stacksize,
but the proper way is to use TLS to find the thread structure and
not to play games with the thread stacks.

- Convert from makecontext() -> _lwp_makecontext().

- Rely on _lwp_makecontext() to set up the thread identity register.
  This is not currently done (a bug), nor does libpthread use the
  threadreg yet. I'm doing this so it the code can be used by the
  person working on TLS to verify that their threadreg code is working.

PR lib/38741 priority inversion in libpthread breaks apps that use
SCHED_FIFO threads

- Change condvar sync so that we never take the condvar's spinlock without
  first holding the caller-provided mutex. Previously, the spinlock was only
  taken without the mutex in an error path, but it was enough to trigger the
  problem described in the PR.

- Even with this change, applications calling pthread_cond_signal/broadcast
  without holding the interlocking mutex are still subject to the problem
  described in the PR. POSIX discourages this saying that it leads to
  undefined scheduling behaviour, which seems good enough for the time being.

- Elsewhere, use a hash of mutexes instead of per-object spinlocks to
  synchronize entry/exit from sleep queues.

- Simplify how sleep queues are maintained.

- Fix pthread_rwlock_trywrlock() which was broken.

- Add new functions: pthread_mutex_held_np, mutex_owner_np, rwlock_held_np,
  rwlock_wrheld_np, rwlock_rdheld_np. These match the kernel's locking
  primitives and can be used when porting kernel code to userspace.

- Always create LWPs detached. Do join/exit sync mostly in userland. When
  looped on a dual core box this seems ~30% quicker than using lwp_wait().
  Reduce number of lock acquire/release ops during thread exit.

For PR bin/37347:

- Override __libc_thr_init() instead of using our own constructor.
- Add pthread__getenv() and use instead of getenv(). This is used before
  we are up and running and unfortunatley getenv() takes locks.

Other changes:

- Cache the spinlock vectors in pthread__st. Internal spinlock operations
  now take 1 function call instead of 3 (i386).
- Use pthread__self() internally, not pthread_self().
- Use __attribute__ ((visibility("hidden"))) in some places.
- Kill PTHREAD_MAIN_DEBUG.

Check in changes to locking behavior.

pthread__sched() now takes a parameter indicating if the run queue is
already locked. Useful in cases where we already hold pthread__runqueue_lock.

pthread__suspend() now requires callers explicitly lock pthread__runqueue_lock
so we avoid issues with locking order regarding pt_statelock.

Adjsut our lock hierarchy. pthread__runqueue_lock is now above
pt_statelock, triggering the above adjustments. Adjust a lot of routines
as a result. Also move pt_siglock way up in the hierarchy, making
pthread__kill() not violate locking. Add a few extra locks to the list.

Adjust a botch in how pthread_join() used pthread-spintrylock().

pthread_cancel() now correctly walks up the locks with thread->pt_sleeplock.
We can't just lock it, as it points to a lock in the top locking rung. So
try locking, and if it fails, unlock and re-lock. Add code to cope with
the target thread not being in the expected state (which was on a
blocked queue) after we get all the locks.

Add comments to describe what's going on in places that I got confused.

Now that pt_statelock is lower in the locking order than
pthread__runqueue_lock, we can explicitly lock a thread's state before
we take it off the run queue. Adjust sched_yield() accordingly and
add some locking calls that were commented out before (as they'd have
been locking violations).

pthread_next(): now that we can lock the state lock while holding the run
queue lock, do so. Set a thread's state to PT_STATE_RUNNING before we
pull it off the run queue. Since we always are going to switch to it,
set pt_vpid and pt_lastlwp while setting the state. pthread_next
callers now _don't_ set these values.

pthread__kill(): grab pthread__runqueue_lock before target->pt_statelock.
If we want to target a thread that is on a blocked queue, do the
pthread_spintrylock() dance. Unlock all three locks we're running around
with, lock target->pt_sleeplock, then re-lock them all. After we lock,
make sure that the thread's still on a blocked queue before proceeding. If
it's not, either exit (if we wanted to wake out of sigtimedwait())
or start it all over. If the thread has gone live, it may have blocked
our signal and it'd be quite weird to get a signal you'd disabled, just
because the signaller had been running before you blocked it.

Work on cleaning up lock ordering. Turns out that there's not too
much to do, other than fixing an issue in join and one I introduced.

Add volumous comment in pthread_int.h describing how I understand the
current locking to work.

pthread_join() considered pt_flaglock to be a higher-priority lock
than pt_join_lock. Life makes more sense if we flip that.

To not make a lot of routines messy, pthread__runqueue_lock has to be
lower in the lock ordering than pt_statelock. Adapt the changes I made
to sched_yield() to this ordering.

There still is a wart regarding setting the state of a thread
we are taking off of the run (or idle) queue. We can't lock
its pt_statelock as we have the runqueue lock held. For now,
go back to what the old code did which was just write over the info.
This isn't that bad as the only things that should be changing
the state of this thread should be run-queue savy. I need to check
this though....

Check in first step towards having pthread_kill() kill a thread running
on another CPU.

This change adds initial support for deferred signal handling. Just before
we go to sleep and while we hold &self->pt_statelock, check to see if we
have any deferred signals (blocked signals) pending. These are signals
that are not masked in our mask and which have been sent to us. We
were running when they came in. Further, since they are being handled
this way, there's a signal handler defined for them.

So unlock, run the signal handler(s), then carry on.

For condition variables, we consider this a spurious wakeup, so we just
return 0, having not unlocked the mutex. We run the handler with
the mutex held. This shouldn't matter, as you aren't supposed to play
with mutexes in signal handlers. :-)

For nanosleep(), we just process signals, then go to sleep.

For all other cases, we are in a loop with some external predicate. So
we process the signal then roll around the loop to see if it still applies.

In sched_yield(), spin until all deferred signals are gone. Since we hold
self->pt_statelock and that lock has to be held before sending a deferred
signal, no new deferred signals will come in until we're asleep.

While here, be more careful about locking while changing pt_state
to PT_STATE_RUNNING. Grab pt_statelock while doing it, and also set
next->pt_vpid to self->pt_vpid holding the same lock. Will make
the test to determine how to deliver a signal work right (since
a thread's vpid will soon matter in the general case). No longer
set next->pt_vpid in pthread__next().

- Don't take the mutex's spinlock (ptr_interlock) in pthread_cond_wait().
  Instead, make the deferred wakeup list a per-thread array and pass down
  the lwpid_t's that way.

- In pthread_cond_wait(), take the mutex before dealing with early wakeup.
  In this way there should never be contention on the CV's spinlock if
  the app follows POSIX rules (there should only be contention on the
  user-provided mutex).

- Add a port of the kernel's rwlocks. The rwlock's spinlock is only taken if
  there is contention. This is enabled where atomic ops are available. Right
  now that is only i386 and amd64 because I don't have other hardware to
  test with. It's trivial to add stubs for other architectures as long as
  they have compare-and-swap. When we have proper atomic ops the old rwlock
  code can be removed.

- Add a new mutex implementation that's similar to the kernel's mutexes, but
  uses compare-and-swap to maintain the waiters list, so no spinlocks are
  involved. Same caveats apply as for the rwlocks.

- Make the number of spins controllable with the env var PTHREAD_NSPINS.
- Reduce the amount of time that libpthread internal spinlocks are held.
- Rely more on the barrier effects of park/unpark to avoid taking spinlocks.
- Simplify the locking around pthreads and the global queues.
- Align per-thread sync data on a 128 byte boundary.
- Offset thread stacks by a small amount to try and reduce cache thrash.

Mirror a fix made to the kernel's condvars:

After resuming execution, the thread must check to see if it
has been restarted as a result of pthread_cond_signal().  If it
has, but cannot take the wakeup (because of eg a pending Unix
signal or timeout) then try to ensure that another thread sees
it.  This is necessary because there may be multiple waiters,
and at least one should take the wakeup if possible.

starting the pthread library (ie. calling pthread__start()) before
any threads are created turned out to be not such a good idea.
there are stronger requirements on what has to work in a forked child
while a process is still single-threaded.  so take all that stuff
back out and fix the problems with single-threaded programs that
are linked with libpthread differently, by checking if the library
has been started and doing completely different stuff if it hasn't been:
 - for pthread_rwlock_timedrdlock(), just fail with EDEADLK immediately.
 - for sem_wait(), the only thing that can unlock the semaphore is a
   signal handler, so use sigsuspend() to wait for a signal.
 - for pthread_mutex_lock_slow(), just go into an infinite loop
   waiting for signals.

I also noticed that there's a "sem2" test that has never worked in its
single-threaded form.  the problem there is that a signal handler tries
to take a sem_t interlock which is already held when the signal is received.
fix this too, by adding a single-threaded case for sig_trywait() that
blocks signals instead of using the userland interlock.

More signal rearranging:

 - Signal handlers now simply continue executing the current thread,
   rather than trying to put themselves back on the queue that they came
   from, which was rather fragile. As a result, all callers of
   pthread__block() must be prepared to handle spurious wakeups.

 - When a signal arrives for a thread that is blocked in the kernel,
   note this in another field in pthread_st and set a flag. Process the
   signal and set up the trampoline for the handler *after* the thread
   unblocks, so that both the trampoline and the returned state from
   the kernel are preserved.

 - Factor out some code into a pthread__deliver_signal() routine;
   the signal-taking code in pthread_sigmask() should be able to use this
   soon.

This is still gross, and there are still some terrible MP issues lurking here,
but progress crawls along.

This is necessary in order to support e.g. GCC's libjava, which depends
