| * | New POSIX xlocale implementation written from scratch.libressl-v2.6.1 | schwarze | 2017-09-05 | 11 | -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. | |||||
| * | Move mutex, condvar, and thread-specific data routes, pthread_once, and | guenther | 2017-09-05 | 2 | -11/+182 | |
| | | | | | | | | | 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@ | |||||

| * | Mention strtok_r in STANDARDS | jca | 2017-08-31 | 1 | -2/+6 | |
| | | | | | POSIX 2001 instead of POSIX.1c suggested by millert@ and jmc@, ok jmc@ | |||||
| * | two MALLOC_STATS only tweaks; one from David CARLIER, the other found by clang | otto | 2017-08-20 | 1 | -8/+4 | |

| * | Use sendsyslog() directly instead of syslog_r() for the "backwards memcpy" | guenther | 2017-08-14 | 1 | -3/+12 | |
| | | | | | | | | messages, to avoid pulling in piles of other machinery unnecessarily problem observed by schwarze@ ok deraadt@ millert@ | |||||

| * | update the little endian processor list to give it a chance of matching | tedu | 2017-07-08 | 2 | -6/+6 | |

| * | Only access offset if canaries are enabled *and* size > 0, otherwise offset | otto | 2017-07-07 | 1 | -2/+2 | |
| | | | | | is not initialized. Problem spotted by Carlin Bingham; ok phessler@ tedu@ | |||||
| * | The 0x (or 0X) prefix in base 16 is optional so only skip over the | millert | 2017-07-06 | 6 | -18/+18 | |
| | | | | | | | prefix if the character following it is a valid hex char. The C99 standard is clear that given the string "0xy" zero should be returned and endptr set to point to the "x". OK deraadt@ espie@ | |||||
| * | void functions don't return 0 | tb | 2017-07-05 | 1 | -6/+2 | |
| | | | | | From Klemens Nanni | |||||
| * | port the RBT code to userland by making it part of libc. | dlg | 2017-06-19 | 1 | -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@ | |||||
| * | Don't fall back to heapsort() if we would otherwise switch to | millert | 2017-05-30 | 1 | -7/+7 | |
| | | | | | insertion sort (when the number of elements is < 7). | |||||
| * | Support swapping 32-bit aligned elements on 64-bit platforms. | millert | 2017-05-24 | 1 | -22/+63 | |
| | | | | | | Previously they would be swapped a byte at a time when sizeof(int) != sizeof(long). Idea from FreeBSD. | |||||
| * | Document that qsort falls back to heapsort() if the recursion depth | millert | 2017-05-20 | 1 | -3/+13 | |
| | | | | | exceeds 2 lg N and add a reference to the introsort paper. | |||||
| * | Use David Musser's introsort algorithm to fall back to heapsort(3) | millert | 2017-05-20 | 2 | -14/+45 | |
| | | | | | | | when the recursion depth reaches 2*lg(n + 1). This avoids quicksort's quadratic behavior for pathological input without appreciably changing the average run time. | |||||
| * | The BSD qsort() performs tail recursion elimination on the second | millert | 2017-05-17 | 1 | -10/+25 | |
| | | | | | | | | | side of the array being partitioned to save on stack space. Greater savings can be gained by choosing recursion for the smaller side of the partition and eliminating recursion for the larger side. This also results in a small but measurable performance gain. OK otto@ schwarze@ | |||||

| * | - fix bug wrt posix_memalign(3) of blocks between half a page and a page | otto | 2017-05-13 | 2 | -8/+18 | |
| | | | | | | - document posix_memalign() does not play nice with reacallocarray(3) and freezero(3) | |||||

| * | Remove "len < 0" check; len is socklen_t (uint32_t) so can't be | millert | 2017-04-27 | 1 | -2/+2 | |

| * | For small allocations (chunk) freezero only validates the given | otto | 2017-04-22 | 1 | -5/+10 | |
| | | | | | | | | | size if canaries are enabled. In that case we have the exact requested size of the allocation. But we can at least check the given size against the chunk size if C is not enabled. Plus add some braces so my brain doesn't have to scan for dangling else problems when I see this code. | |||||
| * | Fix previous. | visa | 2017-04-20 | 1 | -2/+2 | |
| | | ||||||
| * | Get TCB address using the RDHWR instruction instead of __get_tcb(). | visa | 2017-04-20 | 1 | -4/+5 | |
| | | | | | | | | | | | | 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@ | |||||

| * | New strstr() implementation from musl libc by Rich Felker. This | millert | 2017-04-12 | 1 | -44/+180 | |
| | | | | | | | | | 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@ | |||||

| | | | | | | | no longer has access to the content of a memmory object. It does this by either clearing (if the object memory remains cached) or by calling munmap(2). ok millert@, deraadt@, guenther@ | |||||
