Repair work mostly by markus and millert, first of all solving the primary problem, then adding some additional validation points. And then futher validation in login and su.

Then in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's startup bits before main() gets control. Other cleanups this permits: - move various startup structures into .data.rel.ro - the dl* stubs in libc can be strong and call the callbacks provided via _dl_cb - no longer need to conditionalize dlctl() calls on presence of _DYNAMIC original concept and full diff ok kettenis@ ok deraadt@ Inroduce malloc_conceal() and calloc_conceal().

It is a function that blurs the line between malloc managed memory and application managed memory and exposes some of the internal workings of malloc. If an application relies on that, it is likely to break using another implementation of malloc. If you want usable size x, just allocate x bytes. ok deraadt@ and other devs Implement malloc_usable_size(); ok millert@ deraadt@ and jmc@ for the man page 2018-11-18T16:15:18Z otto otto@openbsd.org 2018-11-18T16:15:18Z urn:sha1:f5c5425b42e670459d60a80ea1f4909e4b6f2357 Implement C11's aligned_alloc(3). ok guenther@ 2018-11-05T08:23:40Z otto otto@openbsd.org 2018-11-05T08:23:40Z urn:sha1:7a9442eb018832ffdacce1f604e34077f7010b77 Add C11's timespec_get(3); minor bump for libc. 2018-10-30T16:28:42Z guenther guenther@openbsd.org 2018-10-30T16:28:42Z urn:sha1:6151004e8c8aaceddcc3cd7708473813e57ddab0 Tweaked diff from brad@ manpage tweaks florian@ and jmc@ ok deraadt@ millert@
