CVS commit: src/sys/kern

Module Name:    src
Committed By:   tls
Date:           Sun Nov 20 01:09:14 UTC 2011

Modified Files:
        src/sys/kern: init_sysctl.c

Log Message:
An undocumented behavior of the sysctl kern.arandom node used to allow
sucking up to 8192 bytes out of the kernel arc4random() generator at a
time.  Supposedly some very old application code uses this to rekey
other instances of RC4 in userspace (a truly great idea).  Reduce the
limit to 256 bytes -- and note that it will probably be reduced to
sizeof(int) in the future, since this node is so documented.
