New Revision: 270348
URL: http://svnweb.freebsd.org/changeset/base/270348
Log:
Add some missing checks for unsupported interfaces (e.g. pflog(4)) when
handling ioctls. While here, remove duplicated checks for a NULL ifp in
in6_control(): this check is already done near the beginning of the
function.
