- Added a simple UDP client that doesn't interfere with requests before sending (for TSIG testing).
- Added support for receiving multiple responses (for XFR testing).
- Added support for connection timeout errors
- Added support for connection termination errors (for EDNS testing).
- Added support for specifying the TSIG key to use (for TSIG testing).
- Added support for $ORIGIN in zone file fragments.
- Simplified rcode checking and use it instead of the yxrrset BADCOOKIE hack.
- In memory channel changes:
- Fixed a trace message that incorrectly referred to client instead of server.
- Fixed a too-tight connection read loop that was preventing Tokio task switching.
- Added connection shutdown detection.
- Fixed incorrect setting of TCP mode to true when UDP mode was requested.
- Re-enable the cookies Stelline test and fix `CookiesMiddlewareProcessor` to allow requests with invalid cookies to proceed if they are authenticated or not required to authenticate.
- Add support for net blocks in the deny list of the cookie middleware processor, ala Unbound, otherwise the deny list is difficult to use beyond a few simple specific IP addresses.
- Improvements to the Stelline server test support needed by the Stelline cookies test:
- Advance mock system time in the Stelline server tests.
- Move Stelline server tests under src/ to permit #cfg(test) based swap out of real system time for mock system time.
- Use the thread_local version of mock_instant to ensure parallel mock time dependent tests don't interfere with each other (such tests also use tokio::time which only works if they run in a single thread).
- Set mock system time to start at zero for each Stelline server test (as expected by the cookies .rpl test script).
- Pass the IP address of the test client to the server so that the cookies middleware can match it against its deny list.
This PR adds an unstable net::server module that enables the creation of UDP
and TCP DNS servers using base transport server, middleware and service building blocks.
