* Add runtime fallback for GRND_INSECURELaurent Bercot2022-06-231-3/+13
| | | | | | | | | | | | | | | | | | | The grndinsecure sysdep is only build-time tested and returns yes if the kernel headers declare GRND_INSECURE. That is a problem because the kernel headers are most likely provided by the toolchain and do not reflect the exact capabilities of the run-time kernel. If the run-time kernel doesn't support that option, getrandom() fails. That made random_buf_early() busyloop. To avoid that, we now fallback to random_devurandom() as an implementation of random_buf_early() if getrandom() fails when used with GRND_INSECURE. This adds a slight amount of overhead to random_buf_early(), so it's probably better to just disable the sysdep at build time if you're making binaries that will run on older kernels.

* Clean up and modernize librandom.Laurent Bercot2016-10-1447-759/+283
| | | | | | | | | | | | | | | | | | | | | | Correct random number generation has historically been suprisingly painful to achieve. There was no standard, every system behaved in a subtly different way, and there were a few userland initiatives to get decent randomness, all incompatible of course. The situation is a bit better now, we're heading towards some standardization. The arc4random() series of functions is a good API, and available on a lot of systems - unfortunately not Linux, but on Linux the new getrandom() makes using /dev/random obsolete. So I removed the old crap in librandom, dropped EGD support, dropped dynamic backend selection, made a single API series (random_* instead of goodrandom_* and badrandom_*), added an arc4random backend and a getrandom backend, and defaulted to /dev/urandom backed up by SURF in the worst case. This should be much smaller and logical. However, it's a major API break, so the skarnet.org stack will be changed to adapt.
