This patch adds C11 threads support (ISO/IEC 9899:2011) based on the
public available n1570 [1].  Since I do not have access to the official
ISO documentation I would ask if there any deviation from the draft
to final doc regarding threads.h please let me know.  However based on
Joseph's comments on a old thread [2] I would expect to N1570 and final
standart to not have any technical differences.

Mostly of the definition required are defined based on POSIX counterparts,
such as thrd_t (pthread_t), once_flag (pthread_once_t), tss_t (pthread_key_t).
The mut_t and cnd_t is also based on internal pthreads fields, but with a
distinct internal layout to avoid possible issues with code interchange
(such as trying to pass POSIX structure on C11 functions and to avoid inclusion
of pthread.h).  The idea is to make it possible to share POSIX internal
implementation for mostly of the code making adjust where only required.

For mostly symbol implementations, direct POSIX pthread internal calls
are used with some exceptions:

  1. thrd_start uses pthread_create internal implementation, but changes
     how to actually calls the start routine.  This is due the difference
     in signature between POSIX and C11, where former return a 'void *'
     and latter 'int'.
     To avoid calling convention issues due 'void *' to int cast, routines
     from C11 threads are started slight different than default pthread one.
     Explicit cast to expected return are used internally on pthread_create
     and the result is stored back to void also with an explicit cast.

  2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering
     errno and to handle expected standard return codes.

  3. thrd_yield also uses internal direct syscall to avoid errno clobbering.

Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu,
powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu,
tile{pro,gx}-linux-gnu, and x86_64-linux-gnu).

Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
arm-linux-gnueabhf, and powerpc64le-linux-gnu.

  To: libc-alpha

This patch adds to testsuite new test cases to test all new introduced
C11 threads functions, types and macros are tested.

Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu,
powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu,
tile{pro,gx}-linux-gnu, and x86_64-linux-gnu).

Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
arm-linux-gnueabhf, and powerpc64le-linux-gnu.

	Adhemerval Zanella  <adhemerval.zanella@linaro.org>
	Juan Manuel Torres Palma  <jmtorrespalma@gmail.com>

	* nptl/Makefile (tests): Add new test files.
	* nptl/tst-call-once.c : New file. Tests C11 functions and types.
	* nptl/tst-cnd-basic.c: Likewise.
	* nptl/tst-cnd-broadcast.c: Likewise.
	* nptl/tst-cnd-timedwait.c: Likewise.

+@chapter ISO C11 threads
+
+This chapter describes @theglibc{} ISO C11 threads implementation.
+To have a deeper understanding of this API, is strongly recomended
+to read ISO/IEC 9899:2011, section 7.26 where ISO C11 threads
+are specified.
+All types and function prototypes are declared in
+@file{threads.h} header.
+@pindex threads.h
+
+@menu
+* Thread Creation and Control:: Support for basic threading.
+* Call Once:: Single call macros and functions.
+* Mutex:: Low level mechanism for mutual exclusion.
+* Condition variable:: High level objects for thread synchronization.
+* Thread-local storage:: Functions to support thread-local storage.
+* C11 error types:: Symbolic constants that represent functions return value.
+@end menu
+
+@node Thread Creation and Control, Call Once, , ISO Threads
+@section Thread Creation and Control
+
+@Theglibc{} implements a set of functions that allow the user to easily
+create and use threads. Many extra functionalities are provided to control
+the behaviour of threads.  The following functions and types are defined:
+
+@deftp {Data Type} {thrd_t}
+Unique object that identifies a thread unequivocally.
+@end deftp
+
+@deftp {Data Type} {thrd_start_t}
+It is a (@code{int (*)(void *)}) typedef that is passed to @code{thrd_create}
+when creating a new thread.  Should point to the first function that thread
+will run.
+@end deftp
+
+@deftypefun int thrd_create (thrd_t *@var{thr}, thrd_start_t @var{func}, void *@var{arg})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Create a new thread executing the function @var{func}.  The object pointed
+by @var{arg} will be taken as @var{func} arguments.  If successful,
+@var{thr} is set to the new thread identifier.
+@end deftypefun
+
+@deftypefun int thrd_equal (thrd_t @var{lhs}, thrd_t @var{rhs})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Checks whether @var{lhs} and @var{rhs} refer to the same thread.
+@end deftypefun
+
+@deftypefun thrd_t thrd_current (void)
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Returns the identifier of the calling thread.
+@end deftypefun
+
+@deftypefun int thrd_sleep (const struct timespec *@var{time_point}, struct timespec *@var{remaining})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Blocks the execution of the current thread for at least until the wall-clock
+time point pointed to by @var{time_point} has been reached.  This function
+does not take an absolute time, but a duration that the thread is required
+to be blocked.
+
+The sleep may resume earlier if a signal that is not ignored is received.
+In such case, if remaining is not NULL, the remaining time duration is stored
+into the object pointed to by @var{remaining}
+@end deftypefun
+
+@deftypefun void thrd_yield (void)
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Provides a hint to the implementation to reschedule the execution of threads,
+allowing other threads to run.
+@end deftypefun
+
+@deftypefun _Noreturn void thrd_exit (int @var{res})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Terminates execution of the calling thread and sets its result code to
+@var{res}.
+If this function is called from a single thread process, the call to this
+function is equivalent to @code{exit(0)}.  Returning from a thread-start
+function is equivalent to calling @code{thrd_exit}.
+@end deftypefun
+
+@deftypefun int thrd_detach (thrd_t @var{thr})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Detaches the thread identified by @var{thr} from the current control thread.
+The resources held by the thread will be freed automatically once the thread
+exits.  The parent thread will never be notified by any @var{thr} signal.
+@end deftypefun
+
+@deftypefun int thrd_join (thrd_t @var{thr}, int *@var{res})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Blocks the current thread until the thread identified by @var{thr} finishes
+execution.  If @var{res} is not a null pointer, the result code of the thread
+is put to the location pointed to by @var{res}.  The termination of the thread
+synchronizes-with the completion of this function.
+The behavior is undefined if the thread was previously detached or joined by
+another thread.
+@end deftypefun
+
+@node Call Once, Mutex, Thread Creation and Control, ISO Threads
+@section Call Once
+
+In order to guarantee single access to a function, @theglibc implements a call
+once function to allow unique access in case a function is required to be
+called only once in presence of several threads.
+
+@deftp {Data Type} {once_flag}
+Complete object type capable of holding a flag used by @code{call_once}
+@end deftp
+
+@deftypevr Macro {} ONCE_FLAG_INIT
+Value established to initialize an object of type @code{once_flag}.
+@end deftypevr
+
+@deftypefun void call_once (once_flag *@var{flag}, void (*@var{func})(void))
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Calls function @var{func} exactly once, even if invoked from several threads.
+The completion of the function @var{func} synchronizes with all previous or
+subsequent calls to @code{call_once} with the same @var{flag} variable.
+@end deftypefun
+
+@node Mutex, Condition variable, Call Once, ISO Threads
+@section Mutex
+
+To have a better control of resources and how threads access them, @theglibc{}
+also implements a mutex object, that allows to avoid race conditions and some
+other concurrency issues.
+
+@deftp {Data Type} {mtx_t}
+Mutex object identifier.
+@end deftp
+
+@deftypefun int mtx_init (mtx_t *@var{mutex}, int @var{type})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Creates a new mutex object with type @var{type}. The object pointed to by
+@var{mutex} is set to an identifier of the newly created mutex.
+@end deftypefun
+
+@deftypefun int mtx_lock (mtx_t *@var{mutex})
+@safety{@prelim{}@mtsafe{}@asunsafe{@asulock{}}@acunsafe{@aculock{}}} Blocks
+the current thread until the mutex pointed to by @var{mutex} is locked.
+The behavior is undefined if the current thread has already locked the mutex
+and the mutex is not recursive.
+Prior calls to @code{mtx_unlock} on the same mutex synchronize-with this
+operation, and all lock/unlock operations on any given mutex form a single
+total order (similar to the modification order of an atomic).
+@end deftypefun
+
+@deftypefun int mtx_timedlock (mtx_t *restrict @var{mutex}, const struct timespec *restrict @var{time_point})
+@safety{@prelim{}@mtsafe{}@asunsafe{@asulock{}}@acunsafe{@aculock{}}}
+Blocks the current thread until the mutex pointed to by @var{mutex} is locked
+or until the wall-clock time pointed to by @var{time_point} has been reached.
+This function takes an absolute time, so if a duration is required, must be
+calculated manually and passed to this function.
+
+The behavior is undefined if the current thread has already locked the mutex
+and the mutex is not recursive.  The behavior is undefined if the mutex does
+not support timeout.
+Prior calls to @code{mtx_unlock} on the same mutex synchronize-with this
+operation (if this operation succeeds), and all lock/unlock operations on any
+given mutex form a single total order (similar to the modification order of
+an atomic).
+@end deftypefun
+
+@deftypefun int mtx_trylock (mtx_t *@var{mutex})
+@safety{@prelim{}@mtsafe{}@asunsafe{@asulock{}}@acunsafe{@aculock{}}}
+Tries to lock the mutex pointed to by @var{mutex} without blocking.  Returns
+immediately if the mutex is already locked.
+Prior calls to @code{mtx_unlock} on the same mutex synchronize-with this
+operation (if this operation succeeds), and all lock/unlock operations on any
+given mutex form a single total order (similar to the modification order of
+an atomic).
+@end deftypefun
+
+@deftypefun int mtx_unlock (mtx_t *@var{mutex})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Unlocks the mutex pointed to by @var{mutex}. The behavior is undefined if the
+mutex is not locked by the calling thread.  This function synchronizes-with
+subsequent @code{mtx_lock}, @code{mtx_trylock}, or @code{mtx_timedlock} on
+the same mutex.  All lock/unlock operations on any given mutex form a single
+total order (similar to the modification order of an atomic).
+@end deftypefun
+
+@deftypefun void mtx_destroy (mtx_t *@var{mutex})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Destroys the mutex pointed to by @var{mutex}.  If there are threads waiting
+on mutex, the behavior is undefined.

+
+The ISO C11 standard also defines several types of mutex that are also
+supported.  They are represented with symbolic constants (enumeration type
+values) and are the following:
+
+@vtable @code
+
+@item mtx_plain
+Mutex type that does not support timeout or test and return.
+
+@item mtx_recursive
+Mutex type that supports recursive locking, what means that owner thread can
+lock it twice or more without causing deadlock.
+
+@item mtx_timed
+Mutex type that supports timeout.

+@section Condition Variable
+
+Mutexes are not the only synchronization mechanisms available.  For some more
+complex tasks, @theglibc{} also implements conditional variables, that allow
+the user to think in a higher level to solve complex synchronization problems.
+They are used to synchronize threads waiting on a certain condition to happen.
+
+@deftp {Data Type} {cnd_t}
+Condition variable object identifier.
+@end deftp
+
+@deftypefun int cnd_init (cnd_t *@var{cond})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Initializes new conditional variable.  The object pointed to by @var{cond}
+will be set to value that identifies the conditional variable.
+@end deftypefun
+
+@deftypefun int cnd_signal (cnd_t *@var{cond})
+@safety{@prelim{}@mtsafe{}@assafe{}@acsafe{}}
+Unblocks one thread that currently waits on conditional variable pointed to

+@end deftypefun
+
+@deftypefun int cnd_broadcast (cnd_t *@var{cond})

+
+@deftypefun int cnd_wait (cnd_t *@var{cond}, mtx_t *@var{mutex})

+by @code{cnd_signal} or @code{cnd_broadcast}, or until the wall-clock time
+pointed to by @var{time_point} has been reached.  The mutex is locked again
+before the function returns.
+As for @code{mtx_timedlock}, this function also takes an absolute time
+rather than a duration.

+variables and are not visible by other threads.  The functions and types
+provided are:
+
+@deftp {Data Type} {tss_t}
+Thread-specific storage object.  Even if shared, every thread will have
+its own instance of that variable with different values.
+@end deftp
+
+@deftp {Data Type} {tss_dtor_t}
+Function pointer of type @code{void(*)(void*)}, used for TSS destructor.
+This function will be called when the current thread calls @code{thrd_exit},
+but never when calling @code{tss_delete} or @code{exit}
+@end deftp

+Used to mark a variable with thread storage duration, that means created

+Integer constant expression representing the maximum number of times that

+
+@deftypefun int tss_create (tss_t *@var{tss_key}, tss_dtor_t @var{destructor})

+@end deftypefun

+feature and every function in this API always returns one of the following
+error codes:
+
+@vtable @code
+
+@item thrd_timedout
+Value returned by a function to indicate that a specified time was reached
+without acquiring the requested resource, usually a mutex or conditional
+variable.
+
+@item thrd_sucess
+Value returned by a function to indicate that the requested operation
+succeded.
+
+@item thrd_busy
+Value returned by a function to indicate that the requested operation
+failed because a resource requested is already in use.
+
+@item thrd_error
+Value returned by a function to indicate that the requested operation
+failed.
+
+@item thrd_nomem

* [PATCH v4 1/4] Clean pthread functions namespaces for C11 threads

From: Adhemerval Zanella @ 2017-05-10 18:41 UTC (permalink / raw)
  To: libc-alpha

This patch adds internal definition (through {libc_}hidden_{proto,def}) and
also change some strong to weak alias for symbols that might be used by C11
threads implementations.

The patchset should not change libc/libpthread functional, although object
changes are expected (since now internal symbols are used instead) and final
exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread
usage of __mmap{64}, __munmap, __mprotect).

Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu,

* [PATCH v4 0/4] Add support for ISO C11 threads.h
@ 2017-05-10 18:41 Adhemerval Zanella
  2017-05-10 18:41 ` [PATCH v4 1/4] Clean pthread functions namespaces for C11 threads Adhemerval Zanella
                   ` (3 more replies)

From: Adhemerval Zanella @ 2017-05-10 18:41 UTC (permalink / raw)
  To: libc-alpha

This is a new update for C11 threads support based on my previous [1]
version.  As discussed in previous thread and after several inputs
the general consensus [2] regarding current C11 DRs related to thread
support [3] (currently 405, 414, 416, 424, 449, 469, 470, 479, 480, and
493) is it should not prevent a implementation based on POSIX primitives.

So I would like to stil propose it for 2.26.  I rebased my previous
version on top os master, so the patchset is simplified and should
contain only C11 threads code.

The main changes from previous version are:

  - Rebased against master to adjust for CALL_THREAD_FCT macro, pthread
    header reorganization, and mmap adjustment.

  - Fixed some wording and typos.

I tested this without regression with a full make/check on
x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu,
powerpc-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf,
sparc64-linux-gnu, and sparcv9-linux-gnu.
