CVS commit: src/sys/kern
Module Name: src
Committed By: tls
Date: Tue Apr 10 15:12:40 UTC 2012
Modified Files:
src/sys/kern: subr_cprng.c
Log Message:
Fix LOCKDEBUG problems pointed out by drochner@
1) Lock ordering in cprng_strong_destroy had us take a spin mutex then
an adaptive mutex. Can't do that. Reordering this requires changing
cprng_strong_reseed to tryenter the cprng's own mutex and skip the
reseed on failure, or we could deadlock.
2) Can't free memory with a valid mutex in it.
