| tyhicks | hello! | 18:10 |
|---|---|---|
| tyhicks | psivaa pointed me to an SRU kernel test failure in one of the security tests | 18:11 |
| tyhicks | after looking into it, it really has nothing to do with the security test and is caused by an ipv4 sysctl change | 18:12 |
| tyhicks | psivaa opened a bug and I commented on it with what I found | 18:12 |
| tyhicks | see bug #1326473 | 18:12 |
| ubot5 | bug 1326473 in linux (Ubuntu) "No /proc/sys/net/ipv4/tcp_syncookies present with 2.6.32-61-generic #123 in -proposed" [Undecided,Incomplete] https://launchpad.net/bugs/1326473 | 18:12 |
| tyhicks | I assume that someone on the kernel team will take over from here? | 18:13 |
| bjf | kamal, can you jump on ^ ? | 18:19 |
| apw | how on earth would we lose tcp_syncookies of all things in a stable update | 18:39 |
| tyhicks | apw: because a change to another ipv4 sysctl entry ended up causing problems | 18:43 |
| tyhicks | apw: I couldn't resist looking into it a little more and gave some more analysis in the bug | 18:44 |
| * tyhicks is really done with it now :) | 18:44 | |
| henrix | tyhicks: yeah, i took a quick look and your analysis makes perfect sense ;) | 18:50 |
| henrix | tyhicks: it may be that the *other* stack trace you see is caused by a similar commit... but i'll take a closer look at it after dinner | 18:51 |
| tyhicks | henrix: yeah, I was curious about the 2nd trace but didn't look at it | 18:51 |
| henrix | tyhicks: there's a similar commit for that sysctl ;) | 18:51 |
| tyhicks | aha :) | 18:52 |
| * henrix -> dinner | 18:52 | |
| apw | heh .. | 19:05 |
| henrix | tyhicks: i confirm that reverting lucid commits 2dc19ed6338a27a78c7a9d47d311ae4ac5302c83 and d77028ffe1a3d6eb5f57c5e5ea87cbfc4ee05eb1 make the 2 stack dumps go away ;) | 20:18 |
| henrix | tyhicks: also, i can see the /proc/sys/net/ipv4/tcp_syncookies again | 20:18 |
| tyhicks | henrix: good to know :) | 20:19 |
| henrix | bjf: tyhicks has proposed a (SAUCE?) patch in bug #1326473. i can give it a quick try or i can start respinning lucid with the 2 reverts (which is more according to the usual policy, i believe) | 20:20 |
| ubot5 | bug 1326473 in linux (Ubuntu) "No /proc/sys/net/ipv4/tcp_syncookies present with 2.6.32-61-generic #123 in -proposed" [High,Triaged] https://launchpad.net/bugs/1326473 | 20:20 |
| bjf | henrix, ogasawara is working on it as well | 20:21 |
| henrix | bjf: oh, ok | 20:21 |
| bjf | henrix, sounds like you are already able to test | 20:21 |
| ogasawara | bjf: I say it sounds like henrix is 2 steps ahead of where I am | 20:21 |
| ogasawara | bjf: if he's confirmed the reverts, I'd go with that | 20:22 |
| bjf | ogasawara, sounds like it to me also | 20:22 |
| henrix | ogasawara: bjf: yep, its easily reproducible :) | 20:22 |
| ogasawara | henrix: I'm just standing up a lucid install right now to try and reproduce | 20:22 |
| ogasawara | henrix: I'll revert the 2 commits and tests here as well for good measure | 20:22 |
| henrix | ogasawara: yeah, i had a kvm install so i just upgraded to -proposed | 20:22 |
| ogasawara | bjf: but don't wait for my 2nd set of ack's, go ahead and proceed | 20:23 |
| henrix | bjf: ogasawara: so, do you want me to go ahead and respin? | 20:24 |
| henrix | (just to make sure we don't dup) :) | 20:24 |
| ogasawara | henrix: I'd vote for you to do the respin, only because you be much faster at doing so than I | 20:26 |
| ogasawara | I think the last time I looked at Lucid was literally back in 2010 | 20:27 |
| henrix | ogasawara: heh, ok. sure :) | 20:27 |
| ogasawara | henrix: anyways, sounds like you and bjf have this sorted. so I'll leave it in the hands of the professionals. | 20:28 |
| henrix | ogasawara: ack | 20:28 |
| henrix | and thanks ;) | 20:28 |
