New Revision: 254557
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=254557
Log:
Add unit test for testing ACL functionality.
There are two unit tests contained here.
1. "Invalid ACL" This attempts to read a bunch of badly formatted ACL entries
and add them to a host access rule. The goal of this test is to be sure that
all invalid entries are rejected as they should be.
2. "ACL" This sets up four ACLs. One is a permit all, one is a deny all, and
the other two have specific rules about which subnets are allowed and which
are not. Then a set of test addresses is used to determine whether we would
allow those addresses to access us when each ACL is applied. This test, by the
way, was what resulted in AST-2010-003's creation.
