wireguard-openbsd/lib/libc/include, branch master WireGuard implementation for the OpenBSD kernel https://git.zx2c4.com/wireguard-openbsd/atom/lib/libc/include?h=master 2021-01-06T19:54:17Z Fix two issues related to thread private data in asr. 2021-01-06T19:54:17Z otto otto@openbsd.org 2021-01-06T19:54:17Z urn:sha1:a7244e9f7440612fd0e5c6899defce35f5a4c4ee - setting up asr in single thread mode and then starting threads using asr would lead to multiple threads sharing the same resolver. - destruction of a thread that has been using asr would leak data. Problem originally reported by Alexey Sokolov and Uli Schlachter. ok kettenis@ gcc3, like clang and unlike our gcc4, doesn't support redirecting builtins 2019-11-25T22:57:28Z guenther guenther@openbsd.org 2019-11-25T22:57:28Z urn:sha1:fb832af54254ed0e740de530dacbdf58442b4a55 like mem{set,cpy,move} or __stack_smash_handler using asm() renaming. So treat gcc3 like clang and mark such functions as protected instead. ok ayoma@ Complete the ld.so boot cleanup: move most libc initialization from 2019-06-02T01:03:01Z guenther guenther@openbsd.org 2019-06-02T01:03:01Z urn:sha1:5c7d06e56e289f4145af6fe3394d5d581f2679bd _csu_finish() to _libc_preinit(), which is an .init_array function in shared libc (and mark it INITFIRST) or a .preinit_array function in static libc, grabbing the _dl_cb callback there from ld.so. Then in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's startup bits before main() gets control. Other cleanups this permits: - move various startup structures into .data.rel.ro - the dl* stubs in libc can be strong and call the callbacks provided via _dl_cb - no longer need to conditionalize dlctl() calls on presence of _DYNAMIC original concept and full diff ok kettenis@ ok deraadt@ Move 'how this works' details from namespace.h to DETAILS 2019-05-13T20:00:32Z guenther guenther@openbsd.org 2019-05-13T20:00:32Z urn:sha1:cfc1d11d2d2b66cc2b843a6a8140179f5ad89413 New futex(2) based rwlock implementation based on the mutex code. 2019-02-13T13:22:14Z mpi mpi@openbsd.org 2019-02-13T13:22:14Z urn:sha1:5ecdd0566b441ae0b99e73f410875e05dc0fa5b7 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 2019-01-10T18:45:33Z otto otto@openbsd.org 2019-01-10T18:45:33Z urn:sha1:fa2b64111b6ceb302725eb7311a0f7b9fbddf988 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 2018-01-18T08:23:44Z guenther guenther@openbsd.org 2018-01-18T08:23:44Z urn:sha1:ae3cb403620ab940fbaabb3055fac045a63d56b7 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 2017-11-04T22:53:57Z jca jca@openbsd.org 2017-11-04T22:53:57Z urn:sha1:a318b99d5fc4aa6b07d4c22670471e27e4e35499 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@
