[Bug 1964686] Re: Command "host non-existent-host-name" hangs forever in Ubuntu jammy
This bug was fixed in the package bind9 - 1:9.18.1-1ubuntu1 --- bind9 (1:9.18.1-1ubuntu1) jammy; urgency=medium * Merge with Debian unstable (LP: #1965981). Remaining changes: - Don't build dnstap as it depends on universe packages: + d/control: drop build-depends on libfstrm-dev, libprotobuf-c-dev and protobuf-c-compiler (universe packages) + d/dnsutils.install: don't install dnstap + d/libdns1104.symbols: don't include dnstap symbols + d/rules: don't build dnstap nor install dnstap.proto - Add back apport: + d/bind9.apport: add back old bind9 apport hook, but without calling attach_conffiles() since that is already done by apport itself, with confirmation from the user. + d/control, d/rules: build-depends on dh-apport and use it - d/NEWS: mention some of the bigger changes in 9.16.0 packaging - d/bind9.named.service: use systemd Type=forking to signal daemon init. This fixes a regression of #900788 where services whose startup depend on name resolutions may fail due to bind9 not being ready (LP #1899902). - d/control: remove optional libjemalloc-dev Build-Depends as it is not in main. - d/NEWS: mention some of the relevant changes in 9.18.0 packaging or functionality that may affect usability. * Dropped changes: - d/p/0003-Remove-spurious-debugging-true.patch: remove development leftover debugging flag from nslookup code (LP: #1961556). [ Incorporated in 9.18.1. ] - SECURITY UPDATE: cache poisoning via bogus NS records + debian/patches/CVE-2021-25220.patch: tighten rules for acceptance of records into the cache in lib/dns/resolver.c. + CVE-2021-25220 [ Incorporated in 9.18.1. ] - SECURITY UPDATE: DoS via specially crafted TCP stream + debian/patches/CVE-2022-0396.patch: ensure correct ordering in lib/isc/netmgr/netmgr.c. + CVE-2022-0396 [ Incorporated in 9.18.1. ] - SECURITY UPDATE: DNAME insist with synth-from-dnssec enabled + debian/patches/CVE-2022-0635.patch: fix logic in lib/dns/rbtdb.c. + CVE-2022-0635 [ Incorporated in 9.18.1. ] - SECURITY UPDATE: Assertion failure on delayed DS lookup + debian/patches/CVE-2022-0667.patch: fix logic in lib/dns/resolver.c. + CVE-2022-0667 [ Incorporated in 9.18.1. ] * Added changes: - d/p/lp1964400-lp1964686-Add-digdelv-system-test-to-check-that-dig-tries-othe.patch, d/p/lp1964400-lp1964686-Add-digdelv-system-test-to-check-timed-out-result-fo.patch, d/p/lp1964400-lp1964686-Add-various-dig-host-tests-for-TCP-UDP-socket-error-.patch, d/p/lp1964400-lp1964686-After-dig-request-errors-try-to-use-other-servers-wh.patch, d/p/lp1964400-lp1964686-Fix-an-issue-in-dig-when-retrying-with-the-next-serv.patch, d/p/lp1964400-lp1964686-Fix-dig-error-when-trying-the-next-server-after-a-TC.patch, d/p/lp1964400-lp1964686-When-resending-a-UDP-request-insert-the-query-to-the.patch: Fix dig error when trying the next server after a TCP connection failure.

Thanks for the reply, Romain. I have prepared a PPA with the current bind9 package in Ubuntu Jammy + the patches from the MR you linked.

[Bug 1964686] Re: Command "host non-existent-host-name" hangs forever in Ubuntu jammy
Hi, I guess to reproduce this I should find my DNS configuration and be able to hardcode it in Docker so it works the same way for everyone. But my environment is a corporate one, so I don't know possible it is to reproduce this with public DNS. Anyway, https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/5954 has been merged 15 minutes ago. Is there a way I can get my hands on an upgraded jammy package containing the latest state of bind 9 (including this just merged pull request) ? If there are some test packages somewhere I can install them over the official jammy packages and re- test in my corporate environment.

As it turns out, the "dig" failure I mentioned in comment 2 may not be entirely related to bug #1964400. I took the liberty of repurposing one of bind9's old bugs to make sure we're also tracking those failures.
