 K900 | o7 asan | 15:38:54 |
 Grimmauld (any/all) | nikstur ran into that too, but after disabling parallel checking it went away for him | 15:39:24 |
| Grimmauld (any/all) | i hate asan | 15:39:27 |
| Grimmauld (any/all) | the best part: i can't repro that one on my machine | 15:39:57 |
| Grimmauld (any/all) | like, at all | 15:40:00 |
 Vladimír Čunát | asan has interactions with PIE, or why the regression? | 15:40:05 |
| Vladimír Čunát | Though the log suggest that kernel is to blame 🤯 | 15:41:21 |
 aloisw | PIE was already in the last staging-next, right? | 15:41:31 |
| Grimmauld (any/all) | yep | 15:41:41 |
| Grimmauld (any/all) | tbh if asan+pie causes trouble depending on host kernel, i'd vote to just skip that check | 15:42:04 |
| Grimmauld (any/all) | * tbh if asan+pie causes trouble depending on build kernel, i'd vote to just skip that check | 15:42:20 |
 Willi Butz | huh. I can't on my local workstation. the above happened on a hetzner ax162
so maybe ignore for now | 15:43:00 |
| Vladimír Čunát | Depends on your kernel perhaps. | 15:43:17 |
| Willi Butz | hetzner 6.12, local 6.16 | 15:44:03 |
| Vladimír Čunát | Doesn't seem suspicious. | 15:44:23 |
| Vladimír Čunát | Hydra's builders use 6.12, BTW. | 15:45:13 |
| Vladimír Čunát | (stable NixOS default generally) | 15:45:23 |
| Grimmauld (any/all) | i am on 6.12 here | 15:45:23 |
| Vladimír Čunát | I'm trying with 6.6 now. | 15:46:12 |
| Willi Butz | ah, so the builder runs some "hardened" variant, not sure if its just linuxPackages_6_12_hardened | 15:49:36 |
| Vladimír Čunát | That might be it. | 15:50:16 |
| Vladimír Čunát | This kind of layout changes feel potentially useful for hardening. | 15:50:42 |
| Vladimír Čunát |
Shadow memory range interleaves with an existing memory mapping.
| 15:51:08 |
| Vladimír Čunát | Still, if the test is unreliable like this, I'm perfectly fine with skipping it. | 15:51:57 |
| Vladimír Čunát | It's the kind of thing that might make sense to keep upstream, as e.g. their CI will be known not to suffer from the hardening. But not suitable as a default in a distro. | 15:53:00 |
| Willi Butz | just saw that it is part of the logs 🤦

 dramforever | this is like a test-only problem right | 15:54:06 |
| Vladimír Čunát | It certainly looks that way to me. | 15:54:32 |
| dramforever | does it mean it's building two copies of everything just to test | 15:56:46 |
| Vladimír Čunát | 🤔 right, it shouldn't have ASAN in the default build. | 15:57:41 |
