* MFC r317707:brooks2017-05-091-0/+4
| | | | | | | | | | | | | | | | | | | Correct an out-of-bounds read in regcomp when the RE is bad. When passed the invalid regular expression "a**", the error is eventually detected and seterr() is called. It sets p->error appropriatly and p->next and p->end to nuls which is a never used char nuls[10] which is zeros due to .bss initialization. Unfortunatly, p_ere_exp() and p_simp_re() both have fall through cases where they set the error, decrement p->next and access it which means a read from whatever .bss variable comes before nuls. Found with regex_test:repet_multi and CHERI bounds checking. Reviewed by: ngie, pfg, emaste Obtained from: CheriBSD Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D10541

| | | | | | | | | | | | | 1) Eliminate possibility to call __*collate_range_cmp() with inclomplete locale (which cause core dump) by removing whole 'table' argument by which it passed. 2) Restore __collate_range_cmp() in __sccl(). 3) Collating [a-z] range in regcomp() works for single byte locales only (we can't do it for other ones). In previous state only first 256 wide chars are considered and all others are just silently dropped from the range.

| | | | | | | | | | | | | | | | | | | | | | libc: regexec(3) adjustment. Change the behavior of when REG_STARTEND is combined with REG_NOTBOL. From the original posting[1]: "Enable the assumption that pmatch[0].rm_so is a continuation offset to a string and allows us to do a proper assessment of the character in regards to it's word position ('^' or '\<'), without risking going into unallocated memory." This change makes us similar to how glibc handles REG_STARTEND | REG_NOTBOL, and is closely related to a soon-to-land fix to sed. Special thanks to Martijn van Duren and Ingo Schwarze for working out some consistent behaviour.

* MFC r300378:pfg2016-05-291-9/+6
| | | | | | | | | | | | | libc/regex: fix two buffer underruns. Fix some rather complex regex issues found on OpenBSD as part of some ongoing work to fix a sed(1) bug. Curiously the OpenBSD tests don't trigger segfaults on FreeBSD but the bugs were confirmed by running a port of FreeBSD's regex under OpenBSD's malloc. Huge thanks to Ingo for confirming the behavior. Obtained from: OpenBSD (CVS 1.20, 1.21)
* MFC r298521;pfg2016-04-281-2/+2
| | | | | | | | | | | regex: prevent two improbable signed integer overflows. In matcher() we used an integer to index nsub of type size_t. In print() we used an integer to index nstates of type sopno, typedef'd long. In both cases the indexes never take negative values. Match the types to avoid any error.
