Module procfs::sys::kernel::random

These files provide additional information about the /dev/random device

Note that some of these entries are only documented in random(4), while some are also documented under proc(5)

Functions

boot_id

This is a read-only file containing a 128-bit UUID generated at boot

entropy_avail

This read-only file gives the available entropy, in bits. This will be a number in the range 0 to 4096

poolsize

This file gives the size of the entropy pool

read_wakeup_threshold

This file contains the number of bits of entropy required for waking up processes that sleep waiting for entropy from /dev/random

uuid

This read-only file randomly generates a fresh 128-bit UUID on each read

write_wakeup_threshold

This file contains the number of bits of entropy below which we wake up processes that do a select(2) or poll(2) for write access to /dev/random. These values can be changed by writing to the file.
