* In srandomdev(), use arc4random_buf() instead of from the kernel.deraadt2014-06-151-4/+3
| | | | discussion with matthew
* Change return value of getentropy() to int 0 for success. Maximumderaadt2014-06-141-9/+27
| | | | | | | | buffersize is enforced strictly, this supplies sufficient entropy payload to act as seed material. Discourage general use of this API, but lock down this function name as the go-to for userland PRNG seeding. Improve documentation. ok miod matthew
* For now... assume success of getentropy() just like we assumed successderaadt2014-06-131-3/+3
| | | | of sysctl(). Mark it with XXX while we consider.
* Remove deprecated RFC2292 ancillary data convenience functions.chrisz2014-06-132-488/+2
| | | | | | They are obsoleted by the RFC3542 api. ok mpi@
* use getgentropy() call. If it fails, things are pretty bad --deraadt2014-06-131-8/+3

* Add new getentropy() system call. Code and pressure from matthew.deraadt2014-06-132-6/+57
| | | | | | | | I accepted that he's right (again) to seperate this out from heavy sysctl API and this will simply a variety of things. Functionname is not used by anyone in the ports tree, so we guess we can use it. Shocking that no application has a function called this. ok matthew & others who pushed him to start this early on

| | | | ok deraadt, jmc, tedu
* Add support for MAP_INHERIT_ZERO.matthew2014-06-131-16/+24
| | | | | | | | This provides a way for a process to designate pages in its address space that should be replaced by fresh, zero-initialized anonymous memory in forked child processes, rather than being copied or shared. ok jmc, kettenis, tedu, deraadt; positive feedback from many more
* Disable the "switch to insertion sort" optimization to avoid quadraticmillert2014-06-121-13/+2

* Fix modf() on sparctobiasu2014-06-071-3/+3
| | | | | | | For large integral values, modf returned uninitialized data in iptr since 1992. Found while debugging python segfaults. ok miod
* Apply "unifdef -D__STDC__" to libc/arch/*/SYS.hmatthew2014-06-0410-109/+10
| | | | | | | | A while back, pascal@ converted our system call stubs from using "cpp | as" to "cc -x assembler-with-cpp", so there's no need to stay compatible with ancient preprocessor semantics. ok miod

* move the ohash functions into libutil by popular demand.espie2014-05-121-2/+2
| | | | | | It's not a standard interface, so it doesn't belong in libc. I hate duplicating the code in client programs, so do beck@, kettenis@, schwarze@, millert@, miod@... and they agree with libutil.
* tweak interface to do the right thing, after useful comments from millert@espie2014-05-125-25/+73

* change to having four freelists per size, to reduce another source oftedu2014-05-121-16/+20
