(Tested on regularly updated Ubuntu 20.04, currently i use systemd 245.4-4ubuntu3.2)
I observe fairly lot of segfaults of systemd-resolve. Frequency vary but … see below.
I have no clue what is the reason. Specific feature of my machine is that apart from normal cable connection (to OpenWRT router) I use OpenVPN for business network (and this submits specific nameserver for myorg.local domain).

~~~~~
I also noted various interesting assertions in journal, in next comment… |
[impact]
systemd-resolved crashes
[test case]
TBD - see original description
[regression potential]
any regression would likely occur while processing sd_event objects, which are used throughout systemd code; this could result in crashes in almost any part of systemd code. However a more likely regression would be leaks of sd_event objects due to failure to release the final ref for an object.
[scope]
This is needed for f/g/h
This might be fixed by upstream commit f814c871e65df8552a055dd887bc94b074037833; if so, that commit isn't included in any systemd release yet, and so is needed in h and earlier.
[other info]
I believe this is caused by a freed sd_event object that is then processed and calls the on_query_timeout callback with invalid state, leading to failed assertion, which causes resolved to crash; that's what analysis of the crash dump appears to indicate. This may be fixed by the upstream commit referenced in [scope], which takes additional refs during function calls. However I haven't reproduced this myself, so I'm only guessing as to the cause and solution at this point.
I'm unsure why this would not occur in bionic, but per comment 5 it seems it doesn't happen in that release.

(Tested on regularly updated Ubuntu 20.04, currently i use systemd 245.4-4ubuntu3.2)
I observe fairly lot of segfaults of systemd-resolve. Frequency vary but … see below.
I have no clue what is the reason. Specific feature of my machine is that apart from normal cable connection (to OpenWRT router) I use OpenVPN for business network (and this submits specific nameserver for myorg.local domain).

[impact]
systemd-resolved crashes
[test case]
TBD - see original description
[regression potential]
any regression would likely occur while processing sd_event objects, which are used throughout systemd code; this could result in crashes in almost any part of systemd code. However a more likely regression would be leaks of sd_event objects due to failure to release the final ref for an object.
[scope]
This is needed for f/g/h
This might be fixed by upstream commit f814c871e65df8552a055dd887bc94b074037833; if so, that commit isn't included in any systemd release yet, and so is needed in h and earlier.
[other info]
I believe this is caused by a freed sd_event object that is then processed and calls the on_query_timeout callback with invalid state, leading to failed assertion, which causes resolved to crash; that's what analysis of the crash dump appears to indicate. This may be fixed by the upstream commit referenced in [scope], which takes additional refs during function calls. However I haven't reproduced this myself, so I'm only guessing as to the cause and solution at this point.
I'm unsure why this would not occur in bionic, but per comment 5 it seems it doesn't happen in that release.
[original description]
(Tested on regularly updated Ubuntu 20.04, currently i use systemd 245.4-4ubuntu3.2)
I observe fairly lot of segfaults of systemd-resolve. Frequency vary but … see below.
I have no clue what is the reason. Specific feature of my machine is that apart from normal cable connection (to OpenWRT router) I use OpenVPN for business network (and this submits specific nameserver for myorg.local domain).

I also noted various interesting assertions in journal, in next comment… |
[impact]
systemd-resolved crashes
[test case]
see original description; I can't reproduce so I'm relying on the reporter(s) to test/verify.
[regression potential]
any regression would likely occur while processing sd_event objects, which are used throughout systemd code; this could result in crashes in almost any part of systemd code. However a more likely regression would be leaks of sd_event objects due to failure to release the final ref for an object.
[scope]
This is needed for f/g/h
This might be fixed by upstream commit f814c871e65df8552a055dd887bc94b074037833; if so, that commit isn't included in any systemd release yet, and so is needed in h and earlier.
[other info]
I believe this is caused by a freed sd_event object that is then processed and calls the on_query_timeout callback with invalid state, leading to failed assertion, which causes resolved to crash; that's what analysis of the crash dump appears to indicate. This may be fixed by the upstream commit referenced in [scope], which takes additional refs during function calls. However I haven't reproduced this myself, so I'm only guessing as to the cause and solution at this point.
I'm unsure why this would not occur in bionic, but per comment 5 it seems it doesn't happen in that release.
[original description]
(Tested on regularly updated Ubuntu 20.04, currently i use systemd 245.4-4ubuntu3.2)
I observe fairly lot of segfaults of systemd-resolve. Frequency vary but … see below.
I have no clue what is the reason. Specific feature of my machine is that apart from normal cable connection (to OpenWRT router) I use OpenVPN for business network (and this submits specific nameserver for myorg.local domain).
