[18:10] <tyhicks> hello!
[18:11] <tyhicks> psivaa pointed me to an SRU kernel test failure in one of the security tests
[18:12] <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
[18:13] <tyhicks> I assume that someone on the kernel team will take over from here?
[18:19] <bjf> kamal, can you jump on ^ ?
[18:39] <apw> how on earth would we lose tcp_syncookies of all things in a stable update
[18:43] <tyhicks> apw: because a change to another ipv4 sysctl entry ended up causing problems
[18:44] <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 :)
[18:50] <henrix> tyhicks: yeah, i took a quick look and your analysis makes perfect sense ;)
[18:51] <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 ;)
[18:52] <tyhicks> aha :)
[18:52]  * henrix -> dinner
[19:05] <apw> heh .. 
[20:18] <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
[20:19] <tyhicks> henrix: good to know :)
[20:20] <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)

[20:21] <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
[20:22] <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 
[20:23] <ogasawara> bjf: but don't wait for my 2nd set of ack's, go ahead and proceed
[20:24] <henrix> bjf: ogasawara: so, do you want me to go ahead and respin?
[20:24] <henrix> (just to make sure we don't dup) :)
[20:26] <ogasawara> henrix: I'd vote for you to do the respin, only because you be much faster at doing so than I
[20:27] <ogasawara> I think the last time I looked at Lucid was literally back in 2010
[20:27] <henrix> ogasawara: heh, ok.  sure :)
[20:28] <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 ;)
