nptl: Handle spurious EINTR when thread cancellation is disabled (BZ#29029)
Some Linux interfaces never restart after being interrupted by a signal
handler, regardless of the use of SA_RESTART [1]. It means that for
pthread cancellation, if the target thread disables cancellation with
pthread_setcancelstate and calls such interfaces (like poll or select),
it should not see spurious EINTR failures due the internal SIGCANCEL.
However recent changes made pthread_cancel to always sent the internal
signal, regardless of the target thread cancellation status or type.
To fix it, the previous semantic is restored, where the cancel signal
is only sent if the target thread has cancelation enabled in
asynchronous mode.
The cancel state and cancel type is moved back to cancelhandling
and atomic operation are used to synchronize between threads. The
patch essentially revert the following commits:
8c1c0aae20 nptl: Move cancel type out of cancelhandling
2b51742531 nptl: Move cancel state out of cancelhandling
26cfbb7162 nptl: Remove CANCELING_BITMASK
However I changed the atomic operation to follow the internal C11
semantic and removed the MACRO usage, it simplifies a bit the
resulting code (and removes another usage of the old atomic macros).
Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
and powerpc64-linux-gnu.

y2038: Add test coverage
It is enabled through a new rule, tests-y2038, which is built only
when the ABI supports the comapt 64-bit time_t (defined by the
header time64-compat.h, which also enables the creation of the
symbol Version for Linux). It means the tests are not built
for ABI which already provide default 64-bit time_t.
The new rule already adds the required LFS and 64-bit time_t
compiler flags.

Fix deadlock when pthread_atfork handler calls pthread_atfork or dlclose
In multi-threaded programs, registering via pthread_atfork,
de-registering implicitly via dlclose, or running pthread_atfork
handlers during fork was protected by an internal lock. This meant
that a pthread_atfork handler attempting to register another handler or
dlclose a dynamically loaded library would lead to a deadlock.
This commit fixes the deadlock in the following way:
During the execution of handlers at fork time, the atfork lock is
released prior to the execution of each handler and taken again upon its
return. Any handler registrations or de-registrations that occurred
during the execution of the handler are accounted for before proceeding
with further handler execution.
If a handler that hasn't been executed yet gets de-registered by another
handler during fork, it will not be executed. If a handler gets
registered by another handler during fork, it will not be executed
during that particular fork.
The possibility that handlers may now be registered or deregistered
during handler execution means that identifying the next handler to be
run after a given handler may register/de-register others requires some
bookkeeping. The fork_handler struct has an additional field, 'id',
which is assigned sequentially during registration. Thus, handlers are
executed in ascending order of 'id' during 'prepare', and descending
order of 'id' during parent/child handler execution after the fork.
Two tests are included:
* tst-atfork3: Adhemerval Zanella <adhemerval.zanella@linaro.org>
This test exercises calling dlclose from prepare, parent, and child
handlers.
* tst-atfork4: This test exercises calling pthread_atfork and dlclose
from the prepare handler.

Fix deadlock when pthread_atfork handler calls pthread_atfork or dlclose
In multi-threaded programs, registering via pthread_atfork,
de-registering implicitly via dlclose, or running pthread_atfork
handlers during fork was protected by an internal lock. This meant
that a pthread_atfork handler attempting to register another handler or
dlclose a dynamically loaded library would lead to a deadlock.
This commit fixes the deadlock in the following way:
During the execution of handlers at fork time, the atfork lock is
released prior to the execution of each handler and taken again upon its
return. Any handler registrations or de-registrations that occurred
during the execution of the handler are accounted for before proceeding
with further handler execution.
If a handler that hasn't been executed yet gets de-registered by another
handler during fork, it will not be executed. If a handler gets
registered by another handler during fork, it will not be executed
during that particular fork.
The possibility that handlers may now be registered or deregistered
during handler execution means that identifying the next handler to be
run after a given handler may register/de-register others requires some
bookkeeping. The fork_handler struct has an additional field, 'id',
which is assigned sequentially during registration. Thus, handlers are
executed in ascending order of 'id' during 'prepare', and descending
order of 'id' during parent/child handler execution after the fork.
Two tests are included:
* tst-atfork3: Adhemerval Zanella <adhemerval.zanella@linaro.org>
This test exercises calling dlclose from prepare, parent, and child
handlers.
* tst-atfork4: This test exercises calling pthread_atfork and dlclose
from the prepare handler.

[PATCH] pthread_once hangs when init routine throws an exception [BZ #18435]
This is another attempt at making pthread_once handle throwing exceptions
from the init routine callback. As the new testcases show, just switching
to the cleanup attribute based cleanup does fix the tst-once5 test, but
breaks the new tst-oncey3 test. That is because when throwing exceptions,
only the unwind info registered cleanups (i.e. C++ destructors or cleanup
attribute), when cancelling threads and there has been unwind info from the
cancellation point up to whatever needs cleanup both unwind info registered
cleanups and THREAD_SETMEM (self, cleanup, ...) registered cleanups are
invoked, but once we hit some frame with no unwind info, only the
THREAD_SETMEM (self, cleanup, ...) registered cleanups are invoked.
So, to stay fully backwards compatible (allow init routines without
unwind info which encounter cancellation points) and handle exception throwing
we actually need to register the pthread_once cleanups in both unwind info
and in the THREAD_SETMEM (self, cleanup, ...) way.
If an exception is thrown, only the former will happen and we in that case
need to also unregister the THREAD_SETMEM (self, cleanup, ...) registered
handler, because otherwise after catching the exception the user code could
call deeper into the stack some cancellation point, get cancelled and then
a stale cleanup handler would clobber stack and probably crash.
If a thread calling init routine is cancelled and unwind info ends before
the pthread_once frame, it will be cleaned up through self->cleanup as
before. And if unwind info is present, unwind_stop first calls the
self->cleanup registered handler for the frame, then it will call the
unwind info registered handler but that will already see __do_it == 0
and do nothing.
