An example configuration which triggers 2053fd510bSchristos this issue would be one which uses the same address:port pair for 2153fd510bSchristos ``listen-on(-v6)`` statements as for ``notify-source(-v6)`` or 2253fd510bSchristos ``transfer-source(-v6)``. While this issue affects all operating 2353fd510bSchristos systems, it only triggers log messages (e.g. "unable to create 2453fd510bSchristos dispatch for reserved port") on some of them. There are currently no 2553fd510bSchristos plans to make such a combination of settings work again. 2653fd510bSchristos 27*4bcbe0a3Schristos- See :ref:`above <relnotes_known_issues>` for a list of all known 28*4bcbe0a3Schristos issues affecting this BIND 9 branch. 29*4bcbe0a3Schristos 3053fd510bSchristosFeature Changes 3153fd510bSchristos~~~~~~~~~~~~~~~ 3253fd510bSchristos 3353fd510bSchristos- The system-provided POSIX Threads read-write lock implementation is 3453fd510bSchristos now used by default instead of the native BIND 9 implementation. 3553fd510bSchristos Please be aware that glibc versions 2.26 through 2.29 had a 3653fd510bSchristos `bug <https://sourceware.org/bugzilla/show_bug.cgi?id=23844>`__ that 3753fd510bSchristos could cause BIND 9 to deadlock. A fix was released in glibc 2.30, and 3853fd510bSchristos most current Linux distributions have patched or updated glibc, with 3953fd510bSchristos the notable exception of Ubuntu 18.04 (Bionic) which is a work in 4053fd510bSchristos progress. If you are running on an affected operating system, compile 4153fd510bSchristos BIND 9 with ``--disable-pthread-rwlock`` until a fixed version of 42b9eb1a82Schristos glibc is available. :gl:`!3125` 4353fd510bSchristos 4453fd510bSchristosBug Fixes 4553fd510bSchristos~~~~~~~~~ 4653fd510bSchristos 4753fd510bSchristos- Fixed re-signing issues with inline zones which resulted in records 4853fd510bSchristos being re-signed late or not at all. 49
