* use _ALIGN() which is uhm a bit OpenBSD-specific, but it means wederaadt2018-03-061-3/+2

* - An error in the multithreaded case could print the wrong function nameotto2018-01-281-12/+23
| | | | | | | - Start with a full page of struct region_info's - Save an mprotect in the init code: allocate 3 pages with none and make the middle page r/w instead of a r/w allocation and two calls to make the guard pages none
* - do not junk pages returned by free_bytes(), all freed chunks are alreadyotto2018-01-261-19/+19
| | | | | junked - freezero(): only clear requested size
* Zap the rotor, it was a wrong idea. Cluebat applied by kshe whootto2018-01-181-6/+3
| | | | | came also up with this diff. Simple, no bias and benchmarks show the extra random calls disappear in te measurement noise.
* Move to ffs(3) for bitmask scanning. I played with this earlier,otto2018-01-181-21/+11
| | | | | | | but at that time ffs function calls were generated instead of the compiler inlining the code. Now that ffs is marked protected in libc this is handled better. Thanks to kshe who prompted me to look at this again.
* Instead of trying to handle ffs() with the normal rename-mark-hidden-and-aliasguenther2018-01-182-4/+6
| | | | | | | 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@

| | | | | _libc___cxa_thread_atexit_impl reference on gcc architectures that breaks the build.

* clang doesn't propagate attributes like "asm labels" and "visibility(hidden)"guenther2017-11-294-11/+23
| | | | | | | | | to builtins like mem{set,cpy,move} and __stack_smash_handler. 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@
* Add the missing STANDARDS section (kettenis@ noticed that these areschwarze2017-11-281-6/+14

* GNU ld has prefixed the contents of .gnu.warning.SYMBOL sectionstb2017-11-287-15/+15

* Revert recent changes to unbreak ports/net/sambajca2017-11-041-2/+8
| | | | | | | | 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 infoguenther2017-10-281-8/+2
| | | | | | | | | | | | | | 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@
* Restore a return that was inadvertently removed from freezero() in r1.234,jsing2017-10-191-1/+2

* New POSIX xlocale implementation written from scratch.libressl-v2.6.1schwarze2017-09-0511-96/+396
| | | | | | | | | | | | Complete in the sense that all POSIX *locale(3) and *_l(3) functions are included, but in OpenBSD, we of course only really care about LC_CTYPE and we only support ASCII and UTF-8. With important help from kettenis@, guenther@, and jca@. Repeated testing in ports bulk builds by naddy@. Additional testing by jca@, sebastia@, dcoppa@, and others. OK kettenis@ dcoppa@, and guenther@ on an earlier version. Riding guenther@'s libc/librthread major bump.

* port the RBT code to userland by making it part of libc.dlg2017-06-191-10/+11
| | | | | | | | | | | | | | src/lib/libc/gen/tree.c is a copy of src/sys/kern/subr_tree.c, but with annotations for symbol visibility. changes to one should be reflected in the other. the malloc debug code that uses RB code is ported to RBT. because libc provides the RBT code, procmap doesn't have to reach into the kernel and build subr_tree.c itself now. mild enthusiasm from many ok guenther@
