* Using a 3-word buffer in the openbsd.randomdata segment, XOR swizzlederaadt2016-05-123-21/+80
| | | | | | the PC/FP/SP registers in the jmpbuf. An old idea (around 1999?) but the random segment sure makes it easy. Lots of help from kettenis ok kettenis
* remove hppa64 port, which we never got going beyond broken single users.deraadt2016-05-1129-944/+3
| | | | | | hppa reverse-stack gives us a valuable test case, but most developers don't have a 2nd one to proceed further with this. ok kettenis

* Oops: the caching of TCB address in single-threaded processes on archs withguenther2016-05-101-2/+2
| | | | slow TCB_GET (alpha, arm, mips64, sh) was broken when I switched CPP symbols.

* Stop using sigreturn for longjmp, just set the signal mask and returnguenther2016-05-093-40/+69
| | | | | | | | | registers ala _longjmp. In setjmp, stop saving the onstack from sigaltstack as it's been unused by longjmp for years. In sig{set,long}jmp, use the internal, hidden names for setjmp/_setjmp/etc to avoid creating PLT entries. build testing deraadt@
* Don't use sigreturn(2) in longjmp(3). Instead use a similar approach as inkettenis2016-05-091-60/+39
| | | | | | _longjmp(3) but also restore the signal mask. ok deraadt@
* remove mention of dbm(3) and surrounding cruft; ok jmc@naddy2016-05-091-4/+2

* Implement longjmp directly and not on top of sigreturn.guenther2016-05-083-98/+125
| | | | | | Use the hidden symbols for internal calls to abort, longjmp, etc ok deraadt@
* No, sigaltstack's onstack flag shouldn't be saved. Delete commentguenther2016-05-081-2/+1
| | | | wondering about that
* Hide __fpu_* and make internal _Qp_* calls go direct.guenther2016-05-086-39/+53

* Simplify sig{set,long}jmp(): just Do The Job instead of calling othersguenther2016-05-081-52/+50

* Unexport sigreturn. Nobody should use it anymore, and it will be removedkettenis2016-05-071-2/+0
| | | | | | | from libc completely in the near future. Riding the libc bump that appeared a few moments ago. ok deraadt@

* stop opening the shadow database by default. only programs that request ittedu2016-05-071-5/+3
| | | | | | via the _shadow functions will open now, preventing some programs running as root from accidentally loading password hashes it into their memory. ok deraadt
* Avoid a transient PLT entry for the internal __getcwd syscall stub forguenther2016-05-071-1/+2
| | | | slightly better code on some archs
* Declare moncontrol(3) APIs in <sys/gmon.h>guenther2016-05-073-7/+11
| | | | | | | Export _gmonparam again. Make gcrt0.o use an reserved name for _monstartup() ok millert@
* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-07149-1658/+2279
| | | | | | | | | | | | | | | | | 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@
