Subject: Unlock most of `kern_vars' variables.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=ad534f1885b0eb48a8f96e714aa65dda6684da66;p=openbsd

Unlock most of `kern_vars' variables.

Add corresponding cases to the kern_sysctl() switch and unlock read-only
variables from `kern_vars'. Unlock KERN_SOMAXCONN and KERN_SOMINCONN
which are atomically read-only accessed only from solisten().
