openbsd/src/lib/libc/include, branch libressl-v2.9.2 A mirror of https://github.com/libressl/openbsd.git https://git.lua4.win/openbsd/atom?h=libressl-v2.9.2 2019-02-13T13:22:14+00:00 New futex(2) based rwlock implementation based on the mutex code. 2019-02-13T13:22:14+00:00 mpi 2019-02-13T13:22:14+00:00 urn:sha1:1cc08e9dfa205222edf7fcc2dfc13ff00f572c84 This implementation reduces contention because threads no longer need to spin calling sched_yield(2) before going to sleep. Tested by many, thanks! ok visa@, pirofti@ Make the "not my pool" searching loop a tiny bit smarter, while 2019-01-10T18:45:33+00:00 otto 2019-01-10T18:45:33+00:00 urn:sha1:93282eac7fa28695cb6880305f3757cbff94eca0 making the number of pools variable. Do not document the malloc conf settings atm, don't know yet if they will stay. Thanks to all the testers. ok deraadt@ Instead of trying to handle ffs() with the normal rename-mark-hidden-and-alias 2018-01-18T08:23:44+00:00 guenther 2018-01-18T08:23:44+00:00 urn:sha1:35352e830aefedf0f54a965ee2aaf8a6ff643231 dance, mark it protected. This works better for both gcc and clang: gcc blocks overriding of internal calls, while clang permits inlining again. ok otto@ Implement __cxa_thread_atexit to support C++11 thread_local scope.

So, when building with clang, instead mark those as protected visibility to get rid of the PLT relocations. We can't take the address of them then, but that's ok: it's a build-time error not a run-time error. ok kettenis@ Revert recent changes to unbreak ports/net/samba 2017-11-04T22:53:57+00:00 jca 2017-11-04T22:53:57+00:00 urn:sha1:b30105a553258a2086424ddb4c40ae559cf8dc7c While it is not clear (to me) why that ports ends up with corrupted shared libs, reverting those changes fixes the issue and should allow us to close p2k17 more smoothly. Discussed with a bunch, ok ajacoutot@ guenther@ Change pthread_cleanup_{push,pop} to macros that store the cleanup info 2017-10-28T21:23:14+00:00 guenther 2017-10-28T21:23:14+00:00 urn:sha1:9990829d38e8d6b09ca6313b53ebc24368889ae0 on the stack instead of mallocing the list and move the APIs from libpthread to libc so that they can be used inside libc. Note: the standard was explicitly written to permit/support this "macro with unmatched brace" style and it's what basically everyone else already does. We xor the info with random cookies with a random magic to detect/trip-up overwrites. Major bump to both libc and libpthread due to the API move. ok mpi@ Move mutex, condvar, and thread-specific data routes, pthread_once, and 2017-09-05T02:40:54+00:00 guenther 2017-09-05T02:40:54+00:00 urn:sha1:03cdb5baba30326ba37cf707fc3767747ee4173e pthread_exit from libpthread to libc, along with low-level bits to support them. Major bump to both libc and libpthread. Requested by libressl team. Ports testing by naddy@ ok kettenis@ Fix previous. 2017-04-20T17:16:32+00:00 visa 2017-04-20T17:16:32+00:00 urn:sha1:818828f96a0a6686b27756ca3019ad13445d6c1a Get TCB address using the RDHWR instruction instead of __get_tcb(). 2017-04-20T16:07:52+00:00 visa 2017-04-20T16:07:52+00:00 urn:sha1:30d54f666e57ad1b211e2356d46da195a9935c29 This gives fast access to the address on systems that implement the UserLocal register. TCB caching is still used when running in the single-threaded mode in order not to penalize old systems. The kernel counterpart of this change must be in place before using this diff! With guenther@
