Review request for Asterisk Developers and Olle E Johansson.


Summary
-------

Issue 17662 was opened by oej since he discovered that using a string comparison for domains was not a viable solution since IPv6 addresses may be represented in many different ways, all of which are considered to be the same address. The patch attached on that issue was my initial attempt at solving the issue.

While I was dabbling in the area, I felt it would be a good idea to add a SIP URI comparison internal test to be sure that all the logic was correct. What I found was that in many regards, the comparison of URI parameters was not working as it should be. That being the case, I largely rewrote the logic of sip_uri_params_cmp() to work correctly.

All SIP URI comparison code has been moved to channels/sip/reqresp_parser.c, including the new test. If you have good ideas for test cases that I haven't thought of yet, please feel free to add comments to the review request.

Also of note, the bugs I found in sip_uri_params_cmp() affect 1.4 and 1.6.2 as well. My plan is to backport the bugfixes to those branches as well once I get a "Ship it!" on this review.


This addresses bug 17662.
