Subject: Unbreak ''route flush'': the kernel now adds local (RTF_LOCAL) routes
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=3d11b3b9ff65771aa24362c42c111c64999c88d3;p=openbsd

Unbreak ''route flush'': the kernel now adds local (RTF_LOCAL) routes
for addresses configured on the system, and prevents userland from
deleting them.  Just skip those routes when flushing.
Problem noticed by mlarkin@, ok henning@ mpi@ claudio@ sthen@ deraadt@
