[$] Removing the Linux /dev/random blocking pool
The random-number generation facilities in the kernel have been reworked
some over the past few months—but problems in that subsystem have been
addressed over an even longer time frame. The most
recent changes were made to stop the getrandom() system call from
blocking for long periods of time at system boot, but the underlying cause
was the behavior of the blocking random pool. A recent patch set would
remove that pool and it would seem to be headed for the mainline kernel.
