src/sys/dev/randomdev, branch main FreeBSD source tree https://cgit-dev.freebsd.org/src/atom?h=main 2000-10-14T10:59:56Z After some complaints about the dir names, the random device is 2000-10-14T10:59:56Z Mark Murray markm@FreeBSD.org 2000-10-14T10:59:56Z urn:sha1:a6278a2a42fc77094f356a290336a0fc395feb05 now in dirs called sys/*/random/ instead of sys/*/randomdev/*. Introduce blocking, but only at startup; the random device will block until the first reseed happens to prevent clients from using untrustworthy output. Provide a read_random() call for the rest of the kernel so that the entropy device does not need to be present. This means that things like IPX no longer need to have "device random" hardcoded into thir kernel config. The downside is that read_random() will provide very poor output until the entropy device is loaded and reseeded. It is recommended that developers do NOT use the read_random() call; instead, they should use arc4random() which internally uses read_random(). Clean up the mutex and locking code a bit; this makes it possible to unload the module again. Remove unneeded includes. 2000-09-21T06:23:16Z Mark Murray markm@FreeBSD.org 2000-09-21T06:23:16Z urn:sha1:4a8612fd41ecde5ed5d1be985c14bf813536c484 Submitted by: phk Include <sys/proc.h> to silence suser() compiler warning. 2000-09-18T20:42:04Z Robert Watson rwatson@FreeBSD.org 2000-09-18T20:42:04Z urn:sha1:c4ff4a846725f24058b6a495b7a7b4b0e00e7b0c Approved by: markm Remove the mtx_t, witness_t, and witness_blessed_t types.

Remove it. This will clean up gratuitous needs for forward references and other namespace pollution.

Instead, use a while loop that pulls items off the head of the queue while the queue is not empty. Large upgrade to the entropy device; mainly inspired by feedback 2000-09-10T13:52:19Z Mark Murray markm@FreeBSD.org 2000-09-10T13:52:19Z urn:sha1:4d87a031c0106945da094f3ea770ea9b4b5fcd6b from many folk. o The reseed process is now a kthread. With SMPng, kthreads are pre-emptive, so the annoying jerkiness of the mouse is gone. o The data structures are protected by mutexes now, not splfoo()/splx(). o The cryptographic routines are broken out into their own subroutines. this facilitates review, and possible replacement if that is ever found necessary.

Some more needs to be done; to follow.
