+Systemtap is a dynamic tracing/instrumenting tool available on Linux. Probes
+that are not fired at run time have close to zero overhead.
+
+The following probes are available for NPTL:
+
+Thread creation & Join Probes
+=============================
+pthread_create - probe for pthread_create
+               arg1 = pointer (pthread_t*) to thread
+               arg2 = pointer (pthread_attr_t*) to attr
+               arg3 = pointer (void *) to start_routine
+               arg4 = arguments to start_routine
+pthread_start - probe for actual thread creation
+              arg1 = struct pthread (members include thread ID, process ID)
+              arg2 = address of start_routine
+              arg3 = pointer to the list of arguments
+pthread_join - probe for pthread_join
+             arg1 = thread ID
+pthread_join_ret - probe for pthread_join return
+                 arg1 = thread ID
+                 arg2 = return value
+
+Lock-related Probes
+===================
+mutex_init    - probe for pthread_mutex_init
+              arg1 = address of mutex lock
+mutex_acquired - probe for succ. return of pthread_mutex_lock
+               arg1 = address of mutex lock
+mutex_timedlock_acquired - probe for succ. return of pthread_mutex_timedlock
+                         arg1 = address of mutex lock
+mutex_entry   - probe for entry to the pthread_mutex_lock function
+              arg1 = address of mutex lock
+mutex_timedlock_entry - probe for entry to the pthread_mutex_timedlock function
+                      arg1 = address of mutex lock, arg2 = address of timespec
+mutex_release - probe for pthread_mutex_unlock after the successful release of a
+                mutex lock
+              arg1 = address of mutex lock
+mutex_destroy - probe for pthread_mutex_destroy
+              arg1 = address of mutex lock
+
+wrlock_entry - probe for entry to the pthread_rwlock_wrlock function
+             arg1 = address of rw lock
+rdlock_entry - probe for entry to the pthread_rwlock_rdlock function
+             arg1 = address of rw lock
+
+rwlock_destroy - probe for pthread_rwlock_destroy
+               arg1 = address of rw lock
+wrlock_acquire_write - probe for pthread_rwlock_wrlock (after getting the lock)
+                     arg1 = address of rw lock
+rdlock_acquire_read - probe for pthread_rwlock_rdlock after successfully getting
+                      the lock
+                    arg1 = address of rw lock
+rwlock_unlock - probe for pthread_rwlock_unlock
+              arg1 = address of rw lock
+
+Condition variable Probes
+=========================
+cond_init - probe for pthread_cond_init
+          arg1 = condition
+          arg2 = attr

+             arg1 = cond
+cond_wait - probe for pthread_cond_wait
+          arg1 = condition
+          arg2 = mutex lock
+cond_timedwait - probe for pthread_cond_timedwait
+               arg1 = condition
+               arg2 = mutex lock
+               arg3 = timespec
+cond_signal - probe for pthread_cond_signal
+            arg1 = condition
+cond_broadcast - probe for pthread_cond_broadcast
+               arg1 = condition

+- we should probably extend pthread_mutexattr_t with a field to create a

+- a new attribute for mutexes: number of times we spin before calling
+sys_futex
+
+- for adaptive mutexes: when releasing, determine whether somebody spins.
+If yes, for a short time release lock.  If someone else locks no wakeup

+- test with threaded process terminating and semadj (?) being applied
+  only after all threads are gone
+
+
+
+- semaphore changes:
+
+  - sem_post should only wake one thread and only when the state of
+    the semaphore changed from 0 to 1
+
+    this also requires that sem_wait and sem_timedwait don't drop the
+    post if they get canceled.
+
+  - possibly add counter field.  This requires reviving the
+    differences between old and new semaphose funtions.  The old ones
+    stay as they are now.  The new once can use an additional field
+    wich is the counter for the number of waiters

+/* Wait on the barrier.
+
+   In each round, we wait for a fixed number of threads to enter the barrier
+   (COUNT).  Once that has happened, exactly these threads are allowed to
+   leave the barrier.  Note that POSIX does not require that only COUNT
+   threads can attempt to block using the barrier concurrently.
+
+   We count the number of threads that have entered (IN).  Each thread
+   increments IN when entering, thus getting a position in the sequence of
+   threads that are or have been waiting (starting with 1, so the position
+   is the number of threads that have entered so far including the current
+   thread).
+   CURRENT_ROUND designates the most recent thread whose round has been
+   detected as complete.  When a thread detects that enough threads have
+   entered to make a round complete, it finishes this round by effectively
+   adding COUNT to CURRENT_ROUND atomically.  Threads that believe that their
+   round is not complete yet wait until CURRENT_ROUND is not smaller than
+   their position anymore.
+
+   A barrier can be destroyed as soon as no threads are blocked on the
+   barrier.  This is already the case if just one thread from the last round
+   has stopped waiting and returned to the caller; the assumption is that
+   all threads from the round are unblocked atomically, even though they may
+   return at different times from the respective calls to
+   pthread_barrier_wait).  Thus, a valid call to pthread_barrier_destroy can
+   be concurrent with other threads still figuring out that their round has
+   been completed.  Therefore, threads need to confirm that they have left
+   the barrier by incrementing OUT, and pthread_barrier_destroy needs to wait
+   until OUT equals IN.
+
+   To avoid an ABA issue for futex_wait on CURRENT_ROUND and for archs with
+   32b-only atomics, we additionally reset the barrier when IN reaches
+   a threshold to avoid overflow.  We assume that the total number of threads
+   is less than UINT_MAX/2, and set the threshold accordingly so that we can
+   use a simple atomic_fetch_add on IN instead of a CAS when entering.  The
+   threshold is always set to the end of a round, so all threads that have
+   entered are either pre-reset threads or post-reset threads (i.e., have a
+   position larger than the threshold).
+   Pre-reset threads just run the algorithm explained above.  Post-reset
+   threads wait until IN is reset to a pre-threshold value.
+   When the last pre-reset thread leaves the barrier (i.e., OUT equals the
+   threshold), it resets the barrier to its initial state.  Other (post-reset)
+   threads wait for the reset to have finished by waiting until IN is less
+   than the threshold and then restart by trying to enter the barrier again.
+
+   We reuse the reset mechanism in pthread_barrier_destroy to get notified
+   when all threads have left the barrier: We trigger an artificial reset and
+   wait for the last pre-reset thread to finish reset, thus notifying the
+   thread that is about to destroy the barrier.
+
+   Blocking using futexes is straightforward: pre-reset threads wait for
+   completion of their round using CURRENT_ROUND as futex word, and post-reset
+   threads and pthread_barrier_destroy use IN as futex word.
+
+   Further notes:
+   * It is not simple to let some of the post-reset threads help with the
+     reset because of the ABA issues that arise; therefore, we simply make
+     the last thread to leave responsible for the reset.
+   * POSIX leaves it unspecified whether a signal handler running in a thread
+     that has been unblocked (because its round is complete) can stall all
+     other threads and prevent them from returning from the barrier.  In this
+     implementation, other threads will return.  However,
+     pthread_barrier_destroy will of course wait for the signal handler thread
+     to confirm that it left the barrier.
+
+   TODO We should add spinning with back-off.  Once we do that, we could also
+   try to avoid the futex_wake syscall when a round is detected as finished.
+   If we do not spin, it is quite likely that at least some other threads will
+   have called futex_wait already.  */

+/* The semaphore provides two main operations: sem_post adds a token to the

+   Conceptually, available tokens can simply be counted; let's call that the

+   be a sem_wait that is blocked on the value because it was zero (using a
+   futex with the value being the futex variable); if there is no blocked
+   sem_wait, sem_post does not need to execute a futex_wake call.  Therefore,
+   we also need to count the number of potentially blocked sem_wait calls
+   (which we call nwaiters).
+
+   What makes this tricky is that POSIX requires that a semaphore can be
+   destroyed as soon as the last remaining sem_wait has returned, and no
+   other sem_wait or sem_post calls are executing concurrently.  However, the
+   sem_post call whose token was consumed by the last sem_wait is considered
+   to have finished once it provided the token to the sem_wait.
+   Thus, sem_post must not access the semaphore struct anymore after it has
+   made a token available; IOW, it needs to be able to atomically provide
+   a token and check whether any blocked sem_wait calls might exist.
+
+   This is straightforward to do if the architecture provides 64b atomics
+   because we can just put both the value and nwaiters into one variable that
+   we access atomically: This is the data field, the value is in the
+   least-significant 32 bits, and nwaiters in the other bits.  When sem_post
+   makes a value available, it can atomically check nwaiters.
+
+   If we have only 32b atomics available, we cannot put both nwaiters and
+   value into one 32b value because then we might have too few bits for both
+   of those counters.  Therefore, we need to use two distinct fields.
+
+   To allow sem_post to atomically make a token available and check for
+   blocked sem_wait calls, we use one bit in value to indicate whether
+   nwaiters is nonzero.  That allows sem_post to use basically the same
+   algorithm as with 64b atomics, but requires sem_wait to update the bit; it
+   can't do this atomically with another access to nwaiters, but it can compute
+   a conservative value for the bit because it's benign if the bit is set
+   even if nwaiters is zero (all we get is an unnecessary futex wake call by
+   sem_post).
+   Specifically, sem_wait will unset the bit speculatively if it believes that
+   there is no other concurrently executing sem_wait.  If it misspeculated,
+   it will have to clean up by waking any other sem_wait call (i.e., what
+   sem_post would do otherwise).  This does not conflict with the destruction
+   requirement because the semaphore must not be destructed while any sem_wait
+   is still executing.  */

+/* The WRITE_BUFFER_SIZE value needs to be chosen such that if we set
+   the socket send buffer size to '1', a write of this size on that
+   socket will block.
+
+   The Linux kernel imposes a minimum send socket buffer size which
+   has changed over the years.  As of Linux 3.10 the value is:
+
+     2 * (2048 + SKB_DATA_ALIGN(sizeof(struct sk_buff)))
+
+   which is attempting to make sure that with standard MTUs,
+   TCP can always queue up at least 2 full sized packets.
+
+   Furthermore, there is logic in the socket send paths that
+   will allow one more packet (of any size) to be queued up as
+   long as some socket buffer space remains.   Blocking only
+   occurs when we try to queue up a new packet and the send
+   buffer space has already been fully consumed.
+
+   Therefore we must set this value to the largest possible value of
+   the formula above (and since it depends upon the size of "struct
+   sk_buff", it is dependent upon machine word size etc.) plus some
+   slack space.  */
