Module random 

Random number generation syscalls: getrandom

Fills request buffers from the kernel entropy pool, which collects entropy from interrupt noise (keyboard, timer, storage IRQs) and RDRAND. Falls back to RDRAND + jitter if the pool is not yet seeded during early boot.

Constants

GRND_FLAGS_MASK 🔒

Valid flags mask.

GRND_NONBLOCK 🔒

GRND_NONBLOCK: return EAGAIN if entropy pool is not yet initialised.

GRND_RANDOM 🔒

GRND_RANDOM: use /dev/random quality (same pool, no distinction in this impl).

Functions

sys_getrandom

SYS_GETRANDOM (601): Fill a buffer with random bytes.
