* Instead of trying to handle ffs() with the normal rename-mark-hidden-and-aliasguenther2018-01-181-2/+1
| | | | | | | 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@
* clang doesn't propagate attributes like "asm labels" and "visibility(hidden)"guenther2017-11-293-6/+6
| | | | | | | | | 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@
* GNU ld has prefixed the contents of .gnu.warning.SYMBOL sectionstb2017-11-285-10/+10

* 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.

| | | | | | | | version uses the two-way string matching algorithm and is faster than the old implementation. With this change, ports that check for strstr having linear complexity time strstr will no longer replace the libc strstr with a private version. OK deraadt@ espie@

* Roll back uintptr_t cast changes after discussions with tedu, otto anddtucker2016-10-163-24/+7
| | | | | | | | | | | | | others. C11 6.5.6.9 says: When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. In these cases the objects are arrays of char so the result is defined, and we believe that the report is based on a compiler incorrectly trapping on defined behaviour.
* Cast pointers to uintptr_t to avoid potential signedness errors.dtucker2016-10-143-7/+24

* The only thing that was translated into multiple languages in OpenBSDbluhm2015-10-251-23/+1
| | | | | | | | | are the errno messages and signal names. Everything else is in English. We are not planning to translate more text. Running a mixed system with less than 1% of the text in native language makes no sense. So remove the NLS support from libc messages. The catopen(3) functions stay as they are. OK stsp@ mpi@

Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h.

| | | | | | | | | | | | | | | | (potentially) MD versions (function dependent, not filename dependent) split out memcpy/memmove/bcopy and strchr/index/strrchr/rindex Bring back amd64 .S versions And the final touch: switch all architectures temporarily to MI memcpy.c, which contains syslog + abort for overlapping copies. A nice harsh undefined behaviour. We will clean the entire userland of the remaining issues in this catagory, then switch to the optimised memcpy which skips the memmove check. I tried to cut this change into pieces, but testing each sub-step on every architecture is too time consuming and mindnumbing. ok miod

* Protect explicit_bzero() from link-time optimizationmatthew2014-06-211-7/+10
| | | | | | | | | | | | | | | | | | | | Modern compiler toolchains are capable of optimizing even across translation unit boundaries, so simply moving the memory clearing into a separate function is not guaranteed to clear memory. To avoid this, we take advantage of ELF weak symbol semantics, and insert a call to an empty, weakly named function. The semantics of calling this function aren't determinable until load time, so the compiler and linker need to keep the memset() call. There are still ways a toolchain might defeat this trick (e.g., optimistically expecting the weak symbol to not be overloaded, and only calling memset() if it is; promoting weak symbols to strong symbols at link-time when emitting a static binary because they won't be interposed; implementing load-time optimizations). But at least for the foreseeable future, these seem unlikely. ok deraadt
