2016-12-31New condvar implementation that provides stronger ordering guarantees.Torvald Riegel
This is a new implementation for condition variables, required after http://austingroupbugs.net/view.php?id=609 to fix bug 13165. In essence, we need to be stricter in which waiters a signal or broadcast is required to wake up; this couldn't be solved using the old algorithm. ISO C++ made a similar clarification, so this also fixes a bug in current libstdc++, for example. We can't use the old algorithm anymore because futexes do not guarantee to wake in FIFO order. Thus, when we wake, we can't simply let any waiter grab a signal, but we need to ensure that one of the waiters happening before the signal is woken up. This is something the previous algorithm violated (see bug 13165). There's another issue specific to condvars: ABA issues on the underlying futexes. Unlike mutexes that have just three states, or semaphores that have no tokens or a limited number of them, the state of a condvar is the *order* of the waiters. A waiter on a semaphore can grab a token whenever one is available; a condvar waiter must only consume a signal if it is eligible to do so as determined by the relative order of the waiter and the signal. Therefore, this new algorithm maintains two groups of waiters: Those eligible to consume signals (G1), and those that have to wait until previous waiters have consumed signals (G2). Once G1 is empty, G2 becomes the new G1. 64b counters are used to avoid ABA issues. This condvar doesn't yet use a requeue optimization (ie, on a broadcast, waking just one thread and requeueing all others on the futex of the mutex supplied by the program). I don't think doing the requeue is necessarily the right approach (but I haven't done real measurements yet): * If a program expects to wake many threads at the same time and make that scalable, a condvar isn't great anyway because of how it requires waiters to operate mutually exclusive (due to the mutex usage). Thus, a thundering herd problem is a scalability problem with or without the optimization. Using something like a semaphore might be more appropriate in such a case. * The scalability problem is actually at the mutex side; the condvar could help (and it tries to with the requeue optimization), but it should be the mutex who decides how that is done, and whether it is done at all. * Forcing all but one waiter into the kernel-side wait queue of the mutex prevents/avoids the use of lock elision on the mutex. Thus, it prevents the only cure against the underlying scalability problem inherent to condvars. * If condvars use short critical sections (ie, hold the mutex just to check a binary flag or such), which they should do ideally, then forcing all those waiter to proceed serially with kernel-based hand-off (ie, futex ops in the mutex' contended state, via the futex wait queues) will be less efficient than just letting a scalable mutex implementation take care of it. Our current mutex impl doesn't employ spinning at all, but if critical sections are short, spinning can be much better. * Doing the requeue stuff requires all waiters to always drive the mutex into the contended state. This leads to each waiter having to call futex_wake after lock release, even if this wouldn't be necessary.

2015-10-16Convert 703 function definitions to prototype style.Joseph Myers
This automatically-generated patch converts 703 function definitions in glibc from old-style K&R to prototype-style. This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

2013-10-01Fix PI mutex check in pthread_cond_broadcast and pthread_cond_signalSiddhesh Poyarekar
Fixes BZ #15988. The check had a typo - it checked for PTHREAD_MUTEX_ROBUST_NP instead of PTHREAD_MUTEX_ROBUST_NORMAL_NP. It has now been replaced by the already existing convenience macro USE_REQUEUE_PI.
2013-02-18FUTEX_*_REQUEUE_PI support for non-x86 codeSiddhesh Poyarekar
Add FUTEX_*_REQUEUE_PI support for the default C code and also add implementations for s-390 and ppc.
