- 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 zonefile/parsed.rs, zonetree/ and related examples/, which
together enable, and show a library user how, to go from a zone file in
presentation format to an in-memory tree of zones which can be queried to
provide an answer, or walked (iterated over).
The tree also supports versioned write operations and a trait based zone
implementation allowing for the in-memory tree for a zone to instead be some
other (a)synchornous backing store (as demonstrated by the mysql-zone.rs
example).
The zonetree module is feature-gated behind the unstable-zonetree feature.
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.
This PR adds experimental support for client transport of DNS messages.
It also adds a new concept of unstable features which gate code that can introduce breaking changes also in non-breaking releases.
This PR fixes scanning (i.e., reading from presentation format) of domain
names that are just the root label. It also fixes how they are displayed:
previously they were empty, now they are displayed as a dot. It also adds a
new method Dname::fmt_with_dot that returns a placeholder type that displays
the name with a dot at the end.
This commit completely redesigns zone file parsing. The primary change is to
convert the scanner into a trait in order to allow multiple zone parser
implementations for different sources and purposes. A number of changes had
to be made in order to make this possible.
The commit also contains an initial implementation of a scanner that modifies
data in-place and can thus returned parsed data with only a minimal amount
of additional allocations. While working, this scanner is more a
proof-of-concept at this point to ensure that the API design is sound.
This commit is based on ideas and code proposed by @not-my-profile in #106.
This commit increases the minimal supported Rust version to 1.59.0.
