| hallyn | jamespage: ^ this is causing trouble (bug 1434999 )... | 01:45 |
| ubottu | bug 1432644 in libvirt (Ubuntu) "duplicate for #1434999 VM permanently tries to read /dev/shm/lttng-ust-wait-5" [High,Confirmed] https://launchpad.net/bugs/1432644 | 01:45 |
| hallyn | meh, i think a deny rule is going to be the way to go | 01:47 |
| hallyn | i don't think removing the dependency is going to be acceptable | 01:49 |
| sarnold | at least the deny could be undone locally if someone wanted to use the tracing capabilities | 01:51 |
| sarnold | rebuilding to put it back would be a lot more effort | 01:51 |
| hallyn | yeah. ok, i guess i'll go ahead and push with that fix | 02:33 |
| hallyn | hm, but what's the path | 02:34 |
| hallyn | /dev/shm/lttng* ? | 02:34 |
| hallyn | http://paste.ubuntu.com/10692865/ | 02:37 |
| hallyn | weird thing is it seems like every error message documented is lttng-ust-wait-5. something magical about 5? | 02:53 |
| hallyn | oh, there is - ./include/lttng/ust-abi.h:45:#define LTTNG_UST_ABI_MAJOR_VERSION 5 | 02:56 |
| hallyn | smb: i pushed a (trivial) libvirt update, just fyi | 02:57 |
| sarnold | hallyn: ah, thanks, that -5 was driving me crazy :) | 03:25 |
| hallyn | i still left it as lttng-ust-wait-* in case major version changes :) | 03:28 |
| sarnold | having seent oo much of python-[123].[5678901234].. kinds of things, a nice * is sometimes perfect :) | 03:29 |
| hallyn | all right, to bed with me - \o | 03:31 |
| sarnold | nn | 03:32 |
| jdstrand | hallyn: interesting-- I was under the impression that the denial was causing vms to not start. I'm of course fine with an explicit deny if it is a harmless denial | 04:15 |

| hallyn | if that's the case then i don' tknow how to handle it. | 14:08 |
| hallyn | i don't think disabling it in ceph will be acceptable | 14:08 |
