Brad House	4bedfd0d55	Add DNS cookie support (RFC7873 + RFC9018) (#833 ) DNS cookies are a simple form of learned mutual authentication supported by most DNS server implementations these days and can help prevent DNS Cache Poisoning attacks for clients and DNS amplification attacks for servers. Fixes #620 Fix By: Brad House (@bradh352)	4 months ago
Brad House	d4282d7665	`ares_destroy()` race condition during shutdown due to missing lock (#831 ) When using EventThreads, the config change cleanup code might manipulate the event update list if it uses file descriptors (such as on Linux). This was being done without a lock. Rework the event enqueuing to handle locking internally to prevent this and to simplify where it is used. This was found by chance during an ASAN CI run.

Brad House	072972aec1	CI: MacOS: move to GitHub Actions instead of Cirrus-CI (#825 ) We've been using a lot of time on Cirrus-CI and our credits run out quickly. MacOS costs 15 compute credits vs 3 compute credits for Linux. Move MacOS testing to GitHub Actions. Fix By: Brad House (@bradh352)	4 months ago

Brad House	2a65901744	CMake MSVC Parallelizm issue: Don't build adig and ahost simultaneously Make ahost a dependency of adig to prevent issues with them both referencing ares_strcasecmp.c and ares_getopt.c. This appears to be a bug in the Cmake generator for MSVC project files. Fixes #796 Fix By: Brad House (@bradh352)	4 months ago

Brad House	6936e672f9	mem leak due to `ares__hosts_entry_to_hostent()` allocation strategy (#824 ) `ares__hosts_entry_to_hostent()` would allocate a separate buffer for each address, but `ares_free_hostent()` expects a single allocation to hold all addresses. This PR fixes this issue and simplifies the logic by using the already-existing `ares__addrinfo2hostent()` to write the hostent instead of coming up with yet another way to write the structure. Fixes #823 Fix By: Brad House (@bradh352)	4 months ago
Brad House	130fd4794b	Reorganize source tree (#822 ) c-ares is getting larger these days and we keep adding source files to the same directory so it can be hard to differentiate core c-ares implementation from library/utility functions. Lets make some subdirectories to help with that and shuffle files around. Fix By: Brad House (@bradh352)	4 months ago
Brad House	58ae7e809a	remove unused test option	4 months ago
Brad House	a548eabbe6	UDP write may fail indicating host isn't reachable (#821 ) UDP is connectionless, but systems use ICMP unreachable messages to indicate there is no ability to reach the host or port, which can result in a `send()` returning an error like `ECONNREFUSED`. We need to handle non-retryable codes like that to treat it as a connection failure so we requeue any queries on that connection to another connection/server immediately. Otherwise what happens is we just wait on the timeout to expire which can greatly increase the time required to get a definitive message. This also adds a test case to verify the behavior. Fixes #819 Fix By: Brad Houes (@bradh352)	4 months ago
Brad House	529906d1cc	Prevent complex recursion during query requeing and connection cleanup c-ares utilizes recursion for some operations, and some of these processes can have unintended side effects, such as if a callback is called that then recurses into the same function. This can cause strange cleanup conditions that lead to crashes. Try to disassociate queries with connections as early as possible and move cleaning up unneeded connections to its own scan rather than trying to detect each time a query is disassociated from a connection.

Brad House	f68992a159	Propagate record duplication error code (#820 ) In c-ares 1.30.0 we started validating strings parsed are printable. This caused a regression in a pycares test case due to a wrong response code being returned as the error was being propagated from a different section of code that was assuming the only possible failure condition was out-of-memory. This PR adds a fix for this and also a test case to validate it. Ref: https://github.com/saghul/pycares/issues/200 Fix By: Brad House (@bradh352)	4 months ago
