| * | Add XOR cookies for rp and sp. Switch from calling obsolete |   guenther | 2016-05-23 | 1 | -77/+75 | |
| | | | | | | | | | sig{block,setmask} to directly using the sigprocmask syscall. Remove longjmperror()-if-passed-real-sigcontext checks and the filling in of sigcontext fields that longjmp ignores. in snaps; ok deraadt@ | |||||
| * | Make _fwalk and _cleanup completely internal to libc | guenther | 2016-05-23 | 2 | -6/+3 | |
| | | | | | ok deraadt@ | |||||
| * | Stop supporting longjmperror(); it's not used, not portable, and the checks | guenther | 2016-05-23 | 11 | -106/+22 | |
| | | | | | | | | longjmp performs can't really be relied upon, even after we got rid of the false positives... ok millert@ deraadt@ | |||||
| * | Remove iruserok(_sa)? and __ivaliduser(sa)? | guenther | 2016-05-23 | 4 | -97/+21 | |
| | | | | | ok millert@ deraadt@ | |||||
| * | Eliminate __check_rhosts_file and __rcmd_errstr: they were only used by | guenther | 2016-05-23 | 2 | -7/+1 | |
| | | | | | | | rlogind and rshd (remember them?) ok deraadt@ | |||||
| * | Stop exposing <sys/localedef.h> and various symbols internal to the libc | guenther | 2016-05-23 | 12 | -39/+129 | |
| | | | | | | | | locale implementation: _{Current,Default}*Locale, __[mn]locale_changed, __mb_len_max_runtime ok millert@ schwarze@ deraadt@ | |||||
| * | Add XOR cookies for r1 (stack) and lr. Switch from calling obsolete | guenther | 2016-05-22 | 2 | -108/+209 | |
| | | | | | | | | | sig{block,setmask} to directly using the sigprocmask syscall. Rewrite sig{set,long}jmp based on {set,long}jmp to avoid the deprecated store/load-multiple instructions. in snaps; ok deraadt@ | |||||
| * | Oh right, actually delete this now that __cerror is unused | guenther | 2016-05-22 | 1 | -61/+0 | |
| | | ||||||
| * | Delete the _SDA_BASE and _SDA2_BASE symbols: they're unnecessary in | guenther | 2016-05-20 | 1 | -5/+1 | |
| | | | | | shared libraries...and I misspelled them anyway | |||||
| * | no more v6only; |   jmc | 2016-05-19 | 1 | -12/+2 | |
| | | ||||||
| * | Add ASM_NOERR for syscalls that never fail and thus don't need the errno | guenther | 2016-05-19 | 1 | -15/+36 | |
| | | | | | | | | setting logic...which can significantly reduce the size of the stub on some archs; 20 syscalls get a trim with this. in snaps for a bit and ok deraadt@ | |||||
| * | Save and restore 'gbr' register when enter/leaving the kernel, and use | guenther | 2016-05-18 | 8 | -110/+35 | |
| | | | | | | | it for the TCB pointer. Eliminate __cerror. "looks good" kettenis@, testing and ok deraadt@ | |||||
| * | Reduce quadruple negation to double negation; |   schwarze | 2016-05-18 | 1 | -10/+10 | |
| | | | | | | | | from Edgar Pettijohn <edgar at pettijohn minus web dot com>. OK jmc@ deraadt@ While here, remove two instances of inconsistent future tense. | |||||
| * | Fix a one-byte buffer underflow (read access only). | schwarze | 2016-05-17 | 1 | -4/+4 | |
| | | | | | | | | | | | This change touches code that only runs when REG_BASIC is given and the regular expression is anchored with ^ _and_ uses backreferences. The segfault could only be triggered when the ^ anchor was inside a leading () subexpression quantified with *. OK martijn@ Patch also proofread by Pedro Giffuni <pfg at FreeBSD dot org>. | |||||
| * | ...and delete the GP setup. Should have been in previous commit | guenther | 2016-05-16 | 1 | -4/+1 | |
| | | ||||||
| * | Eliminate cerror: use PAL_rdunique to get the TCB address directly | guenther | 2016-05-16 | 3 | -59/+12 | |
| | | | | | ok deraadt@ kettenis@ | |||||
| * | Add END() to match ENTRY() macros | guenther | 2016-05-15 | 2 | -3/+8 | |
| | | | | | ok kettenis@ | |||||
| * | TIB conversion is complete, so set errno in the syscall stub and eliminate | guenther | 2016-05-15 | 6 | -21/+33 | |
| | | | | | | | __cerror ok ketternis@ | |||||
| * | remove extra argument; from rafael neves | jmc | 2016-05-13 | 1 | -3/+3 | |

| * | Using a 3-word buffer in the openbsd.randomdata segment, XOR swizzle |   deraadt | 2016-05-12 | 3 | -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. | deraadt | 2016-05-11 | 29 | -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 | |||||
| * | Add RETURN VALUES section and .Xr to memmem(3). | schwarze | 2016-05-11 | 1 | -3/+4 | |
| | | | | | | From Michal Mazurek <akfaew at jasminek dot net>. OK tedu@ | |||||
| * | Oops: the caching of TCB address in single-threaded processes on archs with | guenther | 2016-05-10 | 1 | -2/+2 | |
| | | | | | slow TCB_GET (alpha, arm, mips64, sh) was broken when I switched CPP symbols. | |||||
| * | libc stub is gone, so update the description to cover the remaining use | guenther | 2016-05-09 | 1 | -20/+19 | |
| | | ||||||
| * | Remove sigreturn declaration and the now-unused libc syscall stub | guenther | 2016-05-09 | 14 | -491/+3 | |
| | | ||||||
| * | Stop using sigreturn for longjmp, just set the signal mask and return | guenther | 2016-05-09 | 3 | -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 in |   kettenis | 2016-05-09 | 1 | -60/+39 | |
| | | | | | | | _longjmp(3) but also restore the signal mask. ok deraadt@ | |||||
| * | remove mention of dbm(3) and surrounding cruft; ok jmc@ |   naddy | 2016-05-09 | 1 | -4/+2 | |
| | | ||||||
| * | Implement longjmp directly and not on top of sigreturn. | guenther | 2016-05-08 | 3 | -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 comment | guenther | 2016-05-08 | 1 | -2/+1 | |
| | | | | | wondering about that | |||||
| * | Hide __fpu_* and make internal _Qp_* calls go direct. | guenther | 2016-05-08 | 6 | -39/+53 | |
| | | | | | ok kettenis@ | |||||
| * | Simplify sig{set,long}jmp(): just Do The Job instead of calling others | guenther | 2016-05-08 | 1 | -52/+50 | |
| | | | | | ok kettenis@ | |||||
| * | Unexport sigreturn. Nobody should use it anymore, and it will be removed | kettenis | 2016-05-07 | 1 | -2/+0 | |
| | | | | | | | | from libc completely in the near future. Riding the libc bump that appeared a few moments ago. ok deraadt@ | |||||
| * | remove more dbm pieces | naddy | 2016-05-07 | 2 | -5/+4 | |
| | | ||||||
| * | remove ancient dbm functions (ndbm remains). nothing uses them in forever. |   tedu | 2016-05-07 | 4 | -323/+1 | |
| | | ||||||
| * | stop opening the shadow database by default. only programs that request it | tedu | 2016-05-07 | 1 | -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 for | guenther | 2016-05-07 | 1 | -1/+2 | |
| | | | | | slightly better code on some archs | |||||
| * | Declare moncontrol(3) APIs in <sys/gmon.h> | guenther | 2016-05-07 | 3 | -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. | guenther | 2016-05-07 | 149 | -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@ | |||||
| * | Remove old cruft. |   zhuk | 2016-05-04 | 1 | -95/+0 | |
| | | | | | okay millert@ | |||||
| * | Remove a vax remnant (that was really a no-op anyway). |   millert | 2016-05-02 | 1 | -3/+1 | |

| | | ||||||
| * | Allow setenv(3) and putenv(3) to operate on a NULL environ pointer. | millert | 2016-04-25 | 1 | -11/+15 | |
| | | | | | | | The getenv(3) and unsetenv(3) functions already support this. This will make it easier to emulate the glibc clearenv() function in ports. Based on a diff from and OK jca@ | |||||
