2017-12-12pledge()'s 2nd argument becomes char *execpromises, which becomes theTheo de Raadt
pledge for a new execve image immediately upon start. Also introduces "error" which makes violations return -1 ENOSYS instead of killing the program ("error" may not be handed to a setuid/setgid program, which may be missing/ignoring syscall return values and would continue with inconsistant state) Discussion with many florian has used this to improve the strictness of a daemon
2017-11-28Add a member to be used by __cxa_thread_atexit(). Remove padding which wouldMark Kettenis
now misalign things. ok guenther@
2017-11-28Implement a DL_REFERENCE dlctl. To be used by the upcomingMark Kettenis
__cxa_thread_atexit() implementation. ok guenther@
2017-11-04Revert recent changes to unbreak ports/net/sambaJeremie Courreges-Anglas
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@
2017-10-28Change pthread_cleanup_{push,pop} to macros that store the cleanup infoPhilip Guenther
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@
2017-10-17<elf.h> should make it easier to port our ELF-related tools to other Unices.Martin Pieuchot
For the moment it only includes <sys/exec_elf.h> but the goal is to stop pulling it directly and also replace <elf_abi.h> at least for base applications. ok deraadt@, jasper@, naddy@
2017-10-15Move the thread-related .h files to /usr/src/include/, since thePhilip Guenther
implementation is now spread between libc and librthread. No changes to the content ok mpi@
2017-10-06Use the modern POSIX idiom "-exec ... {} +" instead of find|xargs andChristian Weisgerber
combine the two find(1) invocations into one. From Klemens Nanni; ok tb@
2017-09-10str[n]casecmp_l(3) appeared in POSIX 2008, not in XPG 4;Ingo Schwarze
phessler@ reported that this oversight broke an armv7 bulk build; OK guenther@
2017-09-05New POSIX xlocale implementation written from scratch.Ingo Schwarze
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.

2017-04-20Get TCB address using the RDHWR instruction instead of __get_tcb().Visa Hankala
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@
2017-04-17Change build infrastructure to allow building both gcc and clang. ThisMark Kettenis
doesn't actually flip the switch yet, so aarch64 continues to be the only architecture for which we build clang. ok jsg@, deraadt@

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@

2016-11-12Kill the /usr/include/ssl symlinkJeremie Courreges-Anglas
Proposed some time ago by tedu@, builk build by ajacoutot@
2016-11-08Set owners and permissions only after all headers are installed. Add the -PTheo Buehler
flag to chown to change the symlinks themselves instead of their targets. Also change permissions of all symlinks, so they don't depend on the umask during make build. ok millert
2016-10-16Move libcrypto, librpcsvc and gnu/usr.bin/cc/include from RDIRS to PRDIRS,Theo Buehler
and add prereq targets, so some header files are generated by BUILDUSER during 'make prereq' instead of by root during 'make includes'. Switch the order of 'make cleandir' and 'make includes' during 'make build' so we don't generate many files twice. Except for some machine@ symlinks from ${MACHINE}/stand, /usr/obj is now clean from files generated by root during 'make build'. Those will be cleaned up in a second step. help, testing & ok deraadt, input from natano, further testing rpe

2016-05-07remove dbm.hTed Unangst
2016-05-07Use a Thread Information Block in both single and multi-threaded programs.Philip Guenther
This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@
2016-03-20Prepare for future ld.so/libc bump: update <tib.h> with the definitionsPhilip Guenther
that will be needed and make libpthread work when ld.so/libc.a provide an initial TIB.

2016-03-14Expose snprintf() and vsnprintf() for XPG 5. It predates C99 butTodd C. Miller
