/dev/random has created the same effect as /dev/arandom (and /dev/urandom) for quite some time. Mop up the last few, by using /dev/random where we actually want it, or not even mentioning arandom where it is irrelevant.

[servconf.c servconf.h sshd.c sshd_config.5 sandbox-rlimit.c] [sandbox-systrace.c sandbox.h configure.ac Makefile.in] introduce sandboxing of the pre-auth privsep child using systrace(4). This introduces a new "UsePrivilegeSeparation=sandbox" option for sshd_config that applies mandatory restrictions on the syscalls the privsep child can perform. This prevents a compromised privsep child from being used to attack other hosts (by opening sockets and proxying) or probing local kernel attack surface. The sandbox is implemented using systrace(4) in unsupervised "fast-path" mode, where a list of permitted syscalls is supplied. Any syscall not on the list results in SIGKILL being sent to the privsep child. Note that this requires a kernel with the new SYSTR_POLICY_KILL option. UsePrivilegeSeparation=sandbox will become the default in the future so please start testing it now. feedback dtucker@; ok markus@
