 delroth | hmm, still getting unreproducible linux kernel builds on current staging-next | 12:27:44 |
 raboof | ow - still in the BTF sections or something else? | 12:30:36 |
| delroth | checking now, diffoscope OOMs on my test VM so I have to move the files around :p | 12:30:56 |
| delroth | (turns out ballooning doesn't work super well with panic_on_oom... sometimes memory consumption spikes too quickly and it OOMs before growing the RAM size) | 12:32:11 |
| delroth | https://delroth.net/out.html | 13:59:50 |
| delroth | well, that's not BTF, but that also doesn't tell me much | 13:59:58 |
| delroth | (it took 20min of 100% CPU time for diffoscope to generate this diff) | 14:00:14 |
| delroth | 20 bytes, that's likely some SHA-1 build-ids | 14:02:04 |
| delroth | if I had to guess... | 14:02:06 |
| delroth | Redacted or Malformed Event | 14:20:00 |
| delroth | welp, too bad for future history, can't post images and I'm not going to keep this URL alive forever | 14:20:15 |
| delroth | posted the diff in https://github.com/NixOS/nixpkgs/issues/227800#issuecomment-1551487822 and reopened | 14:20:36 |

really? I thought ability of posting images/videos was one of the reasons for moving over from IRC | 14:23:07 |

really? I thought ability of posting images/videos was one of the reasons for moving over from IRC there's some incident ongoing currently | 14:23:24 |
| delroth | there was a trolling/spam attack on one of the channels recentlyt | 14:23:27 |

| delroth | the two ELFs that have mismatching build-ids are... the 64 bit and 32 bit VDSO, respectively | 14:42:12 |
| delroth | love when someone seems to have had the same issue, sent a patch upstream to LKML, got it reviewed, and then it never got merged: https://lkml.org/lkml/2022/6/8/432 | 14:52:42 |
| delroth | (wouldn't have directly helped because it was specific to MIPS, but I expect it's the same problem) | 14:52:54 |
 @aloisw:kde.org | Why is the build path different to begin with in the NixOS case? | 14:54:36 |
| delroth | no clue! | 14:57:13 |
| delroth | oh, I think I know actually, it's because Nix arbitrarily and silently disables its sandboxing for no good reason sometimes, and I'm not using my usual development machine for these builds because it's not fast enough | 14:58:27 |
| delroth | so that might have been an unsandboxed build | 14:58:38 |
| delroth | https://github.com/NixOS/nix/issues/8165 | 14:59:05 |
| delroth | could be that when it's sandboxed properly the kernel actually builds reproducibly then... I forgot about this issue, and now I'm annoyed that it's still a problem and that I've possibly wasted several hours because of it again so I'm going to go do something else for a while | 15:00:44 |
| raitobezarius | I can try to reproduce | 15:01:10 |
| raitobezarius | What is your attr you're building? | 15:01:15 |
