* QDnsLookup: add support for TLSA recordsThiago Macieira4 days1-0/+234
| | | | | | | | | [ChangeLog][QtNetwork][QDnsLookup] Added support for querying records of type TLSA, which are useful in DNS-based Authentication of Named Entities (DANE). Change-Id: I455fe22ef4ad4b2f9b01fffd17c723aa6ab7f278 Reviewed-by: Mårten Nordheim <marten.nordheim@qt.io>
* QDnsLookup: add the ability to tell if the reply was authenticatedThiago Macieira4 days1-2/+53
| | | | | | | | | This is implemented for DNS-over-TLS and for the native Unix resolver, because I can find no way to get the state of the reply on Windows with the WinDNS.h API. Change-Id: I455fe22ef4ad4b2f9b01fffd17c7bc022ded2363 Reviewed-by: Mårten Nordheim <marten.nordheim@qt.io>
* QDnsLookup: implement DNS-over-TLSThiago Macieira4 days1-2/+92
| | | | | | | | | | | | | | | For the libresolv (Unix) implementation, we already had the packet prepared by res_nmkquery(). This commit moves the res_nsend() to a separate function so QDnsLookupRunnable::query() can be more concise. On the Windows side, this commit creates a separate function for the DoT case, because we now need to use two other functions from WinDNS so we can create a query and parse the reply. The rest is just QSslSocket. Change-Id: I455fe22ef4ad4b2f9b01fffd17c805a3cb0466eb Reviewed-by: Mårten Nordheim <marten.nordheim@qt.io>

| | | | | | | | | | | | | This is just an empty shell for now. The implementation will come in the next commit. [ChangeLog][QtNetwork][QDnsLookup] The class now supports DNS-over-TLS and some other DNSSEC experimental features, on some platforms.

* QDnsLookup: merge some of the domain label expansion codeThiago Macieira2023-06-031-1/+11
| | | | | | | | | | | | | | | Use qt_ACE_do directly from QtCore, to avoid going through Latin1 (US-ASCII) multiple times. Drive-by reduce the size of the buffers from PACKETSZ (512) to the maximum name a label can be (255 plus 1 for the null, just in case). Drive-by replace the last QString::fromWCharArray with QStringView, saving an unnecessary memory allocation before calling QtPrivate::convertToLatin1().

* QDnsLookup: add TimeoutError for timeoutsThiago Macieira2023-05-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We were getting InvalidReplyError because it was simply unknown, which is not very useful. Previously, the Unix code used res_nquery(), which does not return timeouts as a condition. It returns -1 if a timeout did happen, but the content in errno could be a left-over from a previous timeout (see the "Not a typewriter"[1] problem). With the rewrite to using res_nmkquery() and res_nsend() from the previous commits, we can rely on errno being set properly by res_nsend(). $ $objdir/tests/manual/qdnslookup/qdnslookup @0.0.0.1 ; <<>> QDnsLookup 6.6.0 <<>> qdnslookup @0.0.0.1 ;; status: TimeoutError (Request timed out) ;; QUESTION: ;qt-project.org IN A ;; Query time: 10008 ms ;; SERVER: 0.0.0.1#53 Tested on FreeBSD, Linux, macOS, and Windows.

| | | | | | | | | | | | | | I couldn't make my Windows 10 or 11 query a non-standard port. It kept complaining about "The parameter is incorrect.", so as a result the unit test doesn't actually test the new feature there. I can't find a single example of this on the Internet; my speculation is that the backend API that DnsQueryEx uses does not support setting port numbers (DnsQuery_{A,W} didn't offer that option).

| | | | | | | | | | | | | | | | | | | | The change creates a slight source incompatibility. The main things to take care of are * code using printf statements on list.size().

One example is QRandomGenerator::bounded() that has overloads for int, uint and double, but not int64. * Streaming list.size() to a QDataStream will change the format depending on the architecture.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implemented the use of the new QDnsLookup property "nameserver". On the Linux platform, we can specify both IPv4 and IPv6 addresses for the nameserver. On Windows since we are using DnsQuery_W(), which does not have a way of accepting IPv6 addresses, passing IPv6 nameserver address is not supported. On OSX/BSD platforms, specifying IPv6 addresses for nameserver require access to the __res_state_ext structure which is in a private header of libresolv (this header is different for BSDs and OSX). If this feature has to be enabled in the future, we have to figure out a way to access this struct by either accessing the private header or by specifying one of our own. Currently, I'm disabling it till such a solution is arrived at.
