Avoid buffer overflow in RC4 loop comparison (#336) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)

Use external GoogleTest instead of bundling it (#655) GoogleTest should be unbundled. Google changed their guidance a few years back and modern versions of google test cannot build the bundling code file. This PR also updates to use C++14 as is required by modern GoogleTest versions.

Reorganize source tree (#349) Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake). There may be some edge cases that will have to be caught later on for things I'm not aware of. Fix By: Brad House (@bradh352)

Autotools: rework to simplify and fix recent issues (#674) Completely rework the autotools build system, issues have cropped up due to the complexity and could cause issues on even semi-modern Linux systems (Ubuntu 20.04 for example). Changes include: Remove all curl/xc/cares m4 helper files, they go overboard on detections of functions and datatypes. Go back to more plain autoconf macros as they've come a long way over the years. Use known systems and heuristics to determine datatypes for functions like send() and recv(), rather than the error prone detection which required thousands of permutations and might still get it wrong. Remove unneeded configure arguments like --enable-debug or --enable-optimize, its more common for people to simply pass their own CFLAGS on the command line. Only require CARES_STATICLIB definition on Windows static builds, its not necessary ever for other systems, even when hiding non-public symbols. Remove some function and definition detections that were never used in c-ares The test framework is now embedded into the toplevel configure system, there was no need to chain build the test system as it is never built externally to c-ares. As a side-effect of the changes, a configure run completes in about 25% of the original time. This has been tested on various Linux distributions (of varying age), FreeBSD, MacOS, Windows (via MSYS2 with Mingw), and Solaris10/11 (by @dfandrich), AIX 7.3 (by @dfandrich). It is not unlikely that this may have broken more esoteric or legacy systems, and we'll likely need to be ready to accept bug reports and patches, but it has removed over 10k lines of build system code. It is very likely any issues that crop up will add far fewer lines of code to fix such systems. Fixes Bug: #670 Fix By: Brad House (@bradh352)

cmake: improve some include related code (#680) * cmake: avoid warning about non-existing include dir In the Debian build logs I noticed the following warning: cc1: warning: /build/c-ares-1.25.0/test/include: No such file or directory [-Wmissing-include-dirs] This happened because ${CMAKE_INSTALL_INCLUDEDIR} had been added to caresinternal. I believe it has been copied from the "real" lib where it's used in the INSTALL_INTERFACE context. But because caresinternal is never installed we don't need that include here. * cmake: drop CARES_TOPLEVEL_DIR variable The CARES_TOPLEVEL_DIR variable is the same as the automatically created PROJECT_SOURCE_DIR variable. Let's stick to the official one. Also because it is already used at places where CARES_TOPLEVEL_DIR is used as well. Fix By: Gregor Jasny (@gjasny)

Loosen requirements for static c-ares library when building tests It appears that when building tests, it would hardcode enabling building of the c-ares static library. This was probably due to Windows limitations in symbol visibility. This change will use the static library if it exists for tests, always. Otherwise, it will only forcibly enable static libraries for tests on Windows. Fixes: #380 Fix By: Brad House (@bradh352)

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)
