| Unit193 | Yeeeah, glibc this late seems a bit...Well.. Also I keep getting emails. :( | 00:05 |
|---|---|---|
| mwhudson | it would be nice if the releases aligned better | 00:06 |
| sarnold | better 21.10 than 22.04 though :) | 00:07 |
| mwhudson | glibc is getting close finally, it would be nice to to a rebuild and at least amd64 autopkgtest run with a 2.35 snapshot earlier in the next cycle | 00:07 |
| Eickmeyer | I'm assuming I'm in the same boat as everyone else with stuff stuck in proposed due to glibc. | 00:11 |
| Unit193 | sarnold: Someone should quickly sync autoconf 2.70 from Debian, that seems to breaks some things. :D | 00:13 |
| sarnold | Unit193: one two three *not it* | 00:14 |
| Unit193 | So that means autoconf 2.70, gcc-11, and openssl3 will land for TLS? | 00:15 |
| Eickmeyer | I've seen some ideas in my time, and that one could be easily labeled as *BAD*. | 00:15 |

| TJ- | anyone able to think of a workaround for Bug #1940908 ? | 09:25 |

| rbasak | TJ-: I'm not sure I understand why this issue breaks name lookups | 11:18 |
| rbasak | Looking at the upstream issue, it seems like the issue is just that the port unreachable gets sent? Because systemd is stopping listening when it has an answer from elsewhere. | 11:18 |
| rbasak | So if it has an answer from elsewhere, why are name lookups broken? | 11:18 |
| mwhudson | ginggs: cod-tools/ppc64el has regressed in release: https://autopkgtest.ubuntu.com/packages/cod-tools/impish/ppc64el you can stop retrying it :) | 11:27 |
| mwhudson | i meant to make a hint for it but didn't get around to it and now i'm about to fall asleep | 11:27 |
| ginggs | mwhudson: I did see that, it looked like an OOM failure to me, so thought 2 more retries wouldn't hurt | 11:29 |
| mwhudson | ah ok | 11:29 |
| ginggs | mwhudson: i'll do the hint | 11:29 |
| mwhudson | i guess it could be that yes | 11:29 |
| mwhudson | thanks | 11:29 |
| ginggs | or at least the MP for it | 11:30 |
| TJ- | rbasak: sorry, was away. The issue affects it when there is no answer from elsewhere (in our case there is no alternate DNS server - any alternate would have to be on the other side of the same link) | 13:50 |
| rbasak | TJ-: I don't understand why this wouldn't affect everyone such that DNS effectively doesn't work at all. What's different here? | 14:21 |
| === sarnold_ is now known as sarnold | ||
| TJ- | rbasak: I presume its the satellite link latency (Starlink). Most of the time it works but occassionally it fails in this way when latency spikes. Been seeing the effect for a while but only tracked it down yesterday whilst anaylsing an unrelated issue | 14:44 |
| TJ- | rbasak: the only way I can think to workaround it is force all queries over TCP | 14:44 |
| rbasak | TJ-: are you sure it's that bug? Does a local patch fix it? I'm still dubious because it sounded like the bug was fixing something else, rather than just high latency links. | 14:56 |
| rbasak | If resolved is timing out while a UDP request is in transit, then ICMP port unreachable is exactly what I'd expect to see if the reply does eventually arrive. | 14:56 |
| TJ- | rbasak: yes, commit e03d156f78cb5a0ca solves it. In that patch, line 71 of src/resolve/resolved-dns-transaction.c has a comment that explains the issue | 15:05 |
| TJ- | rbasak: oops, thats the merge. the actual commit is 80710ade03d | 15:09 |
| rbasak | Thanks. otp. I'll look again in a bit. | 15:10 |
| TJ- | rbasak: I'll doing some builds here with patches cherry-picked onto Ubuntu packages instead of testing upstream so I'll add to the report once those are tested. | 15:13 |
| TJ- | I was hoping there was an easy workaround! | 15:14 |
