- c-ares version 1.20.1
- This release resolves a significant issue in the 1.20.0 release.
- Bug fixes:
- o Resolve use-after-free issue when TCP connection is terminated before a
- response is returned [17]
- o Reduce number of queries for a load test case to prevent overloading some
- build systems
- o Fix fuzz test build target [18]
- c-ares 1.20.0 notes below:
- This is a feature and bugfix release with some significant internal changes.
- Changes:
- o Update from 1989 MIT license text to modern MIT license text [1]
- o Remove acountry from built tools as nerd.dk is gone [3]
- o Add new ARES_OPT_UDP_MAX_QUERIES configuration option to limit the number of
- queries that can be made from a single ephemeral port [7]
- o Default per-query timeout has been reduced to 2s with a 3x retry count [8]
- o Modernization: start implementing some common data structures that are easy
- to use and hard to misuse. This will make code refactoring easier and remove
- some varied implementations in use. This change also makes ares_timeout()
- more efficient [9]
- o Use SPDX identifiers and a REUSE CI job to verify [12]
- o rand: add support for getrandom() [14]
- Bug fixes:
- o TCP back to back queries were broken [2]
- o Ensure queries for ares_getaddrinfo() are not requeued during destruction [4]
- o ares_getaddrinfo() should not retry other address classes if one address
- class has already been returned [5]
- o Avoid production ill-formed result when qualifying a name with the root
- domain [6]
- o Fix missing prefix for CMake generated libcares.pc [10]
- o DNS server ports will now be read from system configuration instead of
- defaulting to port 53 [11]
- o Remove some unreachable code [13]
- o Replace usages of sprintf with snprintf [15]
- o Fix Watcom instructions and update Windows URLs [16]
