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.
