Brad House	6129d9b79f	Basic support for SIG RR record (RFC 2931 / RFC 2535) (#773 ) With the current c-ares parser, as per PR #765 parsing was broken due to validation that didn't understand the `SIG` record class. This PR adds basic, non validating, and incomplete support for the `SIG` record type. The additional `KEY` and `NXT` which would be required for additional verification of the records is not implemented. It also does not store the raw unprocessed RR data that would be required for the validation. The primary purpose of this PR is to be able to recognize the record and handle some periphery aspects such as validation of the class associated with the RR and to not honor the TTL in the RR in the c-ares query cache since it will always be 0.

Brad House	f70f09f01c	Fix windows y2k38 issue by creating our own timeval datatype (#772 ) As per Issue #760, the use of `struct timeval` is meant for only time differentials, however it could be used to denote an exact timeout. This could lead to y2k38 issues on some platforms. Fixes Issue #760 Fix By: Brad House (@bradh352)	6 months ago

Brad House	75de16cf03	Validate `ares_dns_rr_get_str()` can't return non-valid ASCII strings The DNS message protocol when using non-binary strings needs to be in the ASCII printable range. The function prototype does elude to this but it was not actually validating the string was in anyway valid and could be used. DNS parsing will now fail if an expected string isn't an ASCII string.

Brad House	8d80486e04	Auto reload config on changes (requires EventThread) (#759 ) Automatically detect configuration changes and reload. On systems which provide notification mechanisms, use those, otherwise fallback to polling. When a system configuration change is detected, it asynchronously applies the configuration in order to ensure it is a non-blocking operation for any queries which may still be being processed. On Windows, however, changes aren't detected if a user manually sets/changes the DNS servers on an interface, it doesn't appear there is any mechanism capable of this. We are relying on `NotifyIpInterfaceChange()` for notifications. Fixes Issue: #613 Fix By: Brad House (@bradh352)	6 months ago
David Hotham	2f200b9170	const is fine on ares__channel_[un]lock (#758 ) at https://github.com/c-ares/c-ares/pull/601#issuecomment-1801935063 you chose not to scatter `const` on the public interface because of the plan - now realised - to add threading to c-ares, and in the expectation that even read operations would need to lock the mutex. But the threading implementation has a _pointer_ to a mutex inside the ares channel and as I understand it, that means that it is just fine to mark `ares__channel_lock` (and `ares__channel_unlock`) as taking a `const` channel. It is the pointed-to mutex that is not constant, but C does not propagate `const`-ness through pointers. This PR sprinkles const where appropriate on public interfaces.

Brad House	48e8cd2ed7	ares_getnameinfo(): loosen validation on salen salen validation should be greater than or equal to the required storage size.

Brad House	ce9aa4807c	Apple: reimplement DNS configuration reading (#750 ) The DNS configuration for apple is stored in the system configuration database. Apple does provide an emulated `/etc/resolv.conf` on MacOS (but not iOS), it cannot, however, represent the entirety of the DNS configuration. Alternatively, libresolv could be used to also retrieve some system configuration, but it too is not capable of retrieving the entirety of the DNS configuration. Attempts to use the preferred public API of `SCDynamicStoreCreate()` and friends yielded incomplete DNS information. Instead, that leaves some apple "internal" symbols from `configd` that we need to access in order to get the entire configuration. We can see that we're not the only ones to do this as Google Chrome also does: https://chromium.googlesource.com/chromium/src/+/HEAD/net/dns/dns_config_watcher_mac.cc These internal functions are what what`libresolv` and `scutil` use to retrieve the dns configuration. Since these symbols are not publicly available, we will dynamically load the symbols from `libSystem` and import the `dnsinfo.h` private header extracted from: https://opensource.apple.com/source/configd/configd-1109.140.1/dnsinfo/dnsinfo.h Fix By: Brad House (@bradh352)	7 months ago
