* sigsetmask() and sigblock() are no longer used by any setjmp implementationguenther2016-09-261-3/+3

* Add functions for SHA512/256. The standard says you're supposed to starttedu2016-09-031-2/+11
| | | | | | | | with different magic numbers, so we need to add some functions instead of just asking the user to truncate as desired. Sigh. SHA512 is quite a bit faster than SHA256 on 64 bit CPUs, but 256 bit hashes are usually quite sufficient. Best of both. ok deraadt tom

| | | | | | | | | | | | | | | | | 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@

* Rearrange C runtime bits: now that ld.so exports environ and __progname,guenther2016-03-201-1/+6
| | | | | | | | | | | move their definitions and initialization in static links to libc.a Make crt0 always invoke a new func _csu_finish() in libc to process the auxv and to either register the ld.so cleanup function (in dynamic links) or initialize environ and __progname and do MC_DISABLE_KBIND (in static links). In libc, get pagesize from auxv; cache that between getpagesize() and sysconf(_SC_PAGESIZE) ok mpi@ "good time" deraadt@

* Use reentrant versions of getpw{nam,uid} and getgr{nam,gid} withinmillert2015-11-242-6/+6
| | | | | | | libc to avoid reusing the static buffers returned by the non-reentrant versions. Since this is inside libc we can use constants for the buffer sizes instead of having to call sysconf(). OK guenther@ deraadt@
* Add _shadow variants to the two popular getpw functions (uid and nam).tedu2015-11-181-1/+3
| | | | | | | | | This version of the function will always open the secure/shadow/master password files. Soon, the regular variants of these functions will not. (Intermixing shadow and regular gets a little weird; don't do that.) Not using struct spwd and getspwnam functions to reduce churn in callers. Should just be a one line diff in most places. ok deraadt
* Split the intra-thread functionality from kill(2) into its own syscallguenther2015-11-101-1/+2
| | | | | | | | | | | | thrkill(2), rolling the kill(2) syscall number with the ABI change to avoid breaking binaries during during the transition. thrkill(2) includes a 'tcb' argument that eliminates the need for locking in pthread_kill() and simplifies pthread_cancel(). Switch __stack_smash_handler() to use thrkill(2) and explicitly unblock SIGABRT. Minor bump to both libc and libpthread: make sure you install a new kernel! ok semarie@
* libc.so can't be unloaded, so move the hidden atexit() and pthread_atfork()guenther2015-11-102-2/+27
| | | | | | | | | | | stubs for the executable from crtbegin.o into libc, which lets them be excluded from static links that don't use them. For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini sections for libc aren't called at the right times anyway, so it's good that they're unused. libc.so just needs __guard_local and the .note.openbsd.ident section, so add them to stack_protector.c for now (this will be improved) "good time" deraadt@
* Do not include a timestamp in the syslog message. There is no need --deraadt2015-10-311-2/+2
| | | | | | | | syslogd will fill it in immediately upon reception on the other side of sendsyslog(2). Our libc only talks to our syslogd, which will fix the timestamp before forwarding. syslog_r has done this for a long time already. ok tedu bluhm

* Merge the sigaction() and sigprocmask() overloads/wrappers from libpthreadguenther2015-10-231-5/+5
| | | | | | | | | into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@
