* Support IPv6 in addr queries.Mark Wooding2014-10-19
| | | | | | | | | | | | | | This is the end-game. Add flags and options to allow clients and administrators to choose which address families they want returned. For logical compatibility with old clients, don't return foreign address families unless explicitly requested. Lots of tests are modified to select only IPv4 addresses. There's nothing else up my sleeve. A new test is added for the additional functionality; more are expected later.

* src/types.c: Start on IPv6 support in adns_r_addr queries.Mark Wooding2014-10-19
| | | | | | | | | | | | | | | | | | | | The way addr queries work internally is now very different. The toplevel query is now `virtual', and exists to spawn subqueries for each applicable address type (currently hardcoded to A only, but this will change later). The toplevel query has a callback function which assembles its answer from the various child queries, and there's a collection of support machinery too. (Some of the bookkeeping done during this may seem unnecessary, but it will come in handy later.) Because more of the work is now done in internal query callbacks, some of the answers in the tests are reported in different order. See `Reentrancy: Avoid reentrant callbacks' for more detailed explanation of a similar change.

* Reentrancy: Avoid reentrant callbacksIan Jackson2014-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid making reentrant callbacks for internal queries during other processing. Currently there is a theoretical reentrancy bug in adns__submit_internal, if the internal query can itself be persuaded to fail immediately. The result would be a reentrant call to callback() for the child query inside functions like typei->parse. The possibility of such reentrancy is a bug waiting to happen - and indeed we are going to introduce more complicated query submissions which are more likely to fail immediately, turning this from a theoretical to a real bug. Solve this as follows: when an internal query completes, just put it on a list. Whenever we are on our way out of adns, we look through this list and make the callbacks (until the list is empty). This means that a fair amount of code needs to be taught that it might encounter queries in this callback pending state. We have to update some of the tests' expected output: Because adns now processes the callback later, a number of the parallel subqueries made by some of the tests end up finishing before being cancelled - and therefore the replies to those subqueries don't show up in the debug output as unrecognised. Also, in case-norecurse, the deferral of the callback causes the order of result reporting to be changed: the main query due to subqueries finishing (`PTR(checked)') ends up later on the results queue than the other queries dealt with in the same event loop iteration. (The actual answer packet to final query, `CNAME(-)', arrives later.) Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* src/: Support for transport over IPv6 (and other protocol families).Mark Wooding2014-10-19
| | | | | | | | | We create a UDP socket for each distinct protocol family during initialization, and then use the appropriate one for each server. The changes are somewhat invasive, but not really very complicated. Signed-off-by: Mark Wooding <mdw@distorted.org.uk> Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

* regress/: Use adns_addr2text/text2addr instead of inet_aton/ntoa.Mark Wooding2014-10-19

* src/: Support IPv6 reverse queries.Mark Wooding2014-10-19
| | | | | | | | | | | | | | | | This involves moving most of the label parser in ckl_ptr, and the reverse-domain constructor, into addrfam and teaching them about IPv6. The label parser is a little tricky because it involves keeping track of a parse state for each possible address family until we run out of possibilities or the parse is complete. Moving the reverse-domain constructor introduces a slightly unpleasant hack: because knowledge of the right reverse-lookup zone belongs in addrfam, we get adns_submit_reverse to pass a sentinel through _reverse_any to addrfam.

* src/, client/: Support for AAAA lookups.Mark Wooding2014-10-19

* src/adns.h, src/types.c: Now adns_rr_addr can hold a sockaddr_in6.Mark Wooding2014-10-12
| | | | | | | | | | | | | | | | | | This uses the recently introduced variable-size record structure machinery so that only clients compiled against the new header file see the larger record structure. Note that we don't even try to actually do lookups for IPv6 addresses. That will come later on. This is just about sorting out the binary interface. Arrange that regress/case-brokenmail.sys asks for the correct record size, because otherwise the answers get printed out wrongly. [ I have done git-grep sizeof on a version of the head of this series and found no un-corrected uses of sizeof(adns_rr_addr) -iwj. ] Signed-off-by: Mark Wooding <mdw@distorted.org.uk>
* Bodge adns_r_addr query-id selection and fix regression tests to match.Mark Wooding2014-10-12
| | | | | | | | | | | | | | A future change is going to change how query-ids are allocated for adns_r_addr queries. So here we apply a simple bodge which will produce the same allocation pattern, but without the complexity of the rest of the change, and fix the test suite to match. I used the script regress/hack-query-ids to help me modify the case-*.sys files, though this was primarily a rather tedious manual process.

* src/, regress/: Prepare for early failures in PTR queries.Mark Wooding2014-10-12
| | | | | | | | | | | | | | | | | Soon we're going to change the way adns_r_ptr queries work: in particular, queries with names which can't be parsed back into addresses will be rejected during submission rather than waiting for the answer to the initial PTR question to come back. So here we apply a really simple temporary hack to adns_submit which approximately captures the behaviour we're after, and adjust the various test cases to match. We'll take this hack out when we make the proper change to the PTR handling. Hopefully this will persuade reviewers that there's nothing up my sleeves while I mess with the regression tests.

* regress/r1test: Support an `ADNS_TEST_DEBUG' env var.Mark Wooding2014-10-12
| | | | | | | | | | | | | | | | | | | | Amazingly, sometimes the tests don't pass. When that happens, it's handy to be able to debug the library and find out why. It's a little tricky to attach GDB to the running process directly. I used the following: $ ADNS_TEST_DEBUG"noip gdbserver localhost:666" ./r1test CASE and then, in another terminal, something like $ noip gdb adnstest_s (gdb) target remote localhost:666 to debug the program.
