AceLancking: what kind of regression test should I do when submit SRU patch?09:06
ckingAceLan, for the "regression potential" part of a SRU, I just want to see a description of where you think regressions could possibly occur.  For fixes such as the PCI power savings, it would be useful to check this on a range of H/W just to see if it works on other devices apart from the ones you are targetting for the fix09:07
AceLancking: got it09:10
AceLancking: about his one "Fix can't disable USB port issue", it's a quirk for specific id, do I need to test it on other machine?09:11
smbAceLan, the more a patch changes in code that potentially is run on a lot of HW, the more we get worried. Sorry for rejecting that one request for the second time, but it just feels like a lot of potential to go wrong09:11
ckingAceLan, I'm very anal about checking stuff, so some checking on other H/W when it comes to some types of fixes is always useful, even the simplest of fixes can sometimes catch one out09:12
ckingit's called the "can I sleep OK overnight with this fix" sanity check ;-)09:13
AceLansmb: thanks for the comment, I'll try to gather more machines for testing09:19
smbAceLan, yw, and again sorry for being a pain. But we try to avoid pain on our side ;)09:20
ckingwell, pain on the user's side too if it goes bad09:30
xnoxin the ADT tests I have09:34
xnox12:18:01 ERROR| [stderr] FAIL: test_061_guard_page (__main__.KernelSecurityTest)09:34
xnox12:18:01 ERROR| [stderr] Userspace stack guard page exists (CVE-2010-2240)09:34
xnoxfailing for kernel, on artful.09:34
xnoxis this test downloaded by autopkgtest from not the source package?09:34
xnoxbecause a package should be able to pass it's autopkgtest. And I don't see how that test is relevant for src:linux triggered by systemd.09:34
xnoxdoes it mean artful started to be vulnerable to CVE-2010-2240 ?09:35
smbxnox, probably rather the test being confused by the new changes due to CVE-2017-1000364 and needing updates. I believe artful picked up the upstream commits which had some compat issues / regressions in corner cases09:43
xnoxsmb, horum. I am no kernel person and the ADT failure looks scary to the uninitiated. Can the ADT test please be "fixed" to e.g. expectfail / skip that test for now, if it is not in fact regressing?09:44
xnoxbut it seems that update to systemd is not causing this kernel regression.09:45
smbxnox, no don't think so to the latter. and the former was was afaik already redirected at the sec team 09:46
IvanovikHi, anyone know the right channel I need to head to if I need NIC internals information?11:11
IvanovikI'm more interested in the datasheet/electronic aspect of it.11:11
IvanovikMy goal is to write a driver.11:11
IvanovikI am fairly familiar with the os/kernel interfacing part.11:11
xnoxsmb, hm.... does this mean kernel security update was released without running adt test?13:34
xnox(one can run adt test with kvm and cloud image using embargoed / locally built packages)13:34
smbxnox, you do realize that the adt test is failing for artful which has a different patch than the rest?13:39
xnoxsmb, yes I do.13:41
xnoxsmb, and my understanding was that linux kernel is built in ppa, with adt tests run, before it is copied into artful-proposed and starts blocking migrations of all packages.13:41
xnoxe.g. we are failing to migrate gcc, systemd, because of the failing adt test.13:41
xnoxsmb, or e.g. copy linux from ppa to silo, and then to the archive.13:43
apwxnox, this was an embargoed cve all things are different13:43
smbxnox, this is a devel kernel which is built into proposed like any other package13:43
xnoxto have a full run of adt tests report, which is automated for the silo ppas.13:43
apwxnox, and regardless the one which is affecting your adt tests is not the things we released via security13:43
xnoxsmb, it was built in the PPA for Canonical Kernel team and then copied into artful-proposed.13:43
apwxnox, why are we so caring about this one failure, we have adt failures which block things all the time13:44
xnoxapw, ok.13:44
apwxnox, we have a system to cope with it13:44
xnoxsure. but things that do clog up -proposed are either resolved quickly or removed from proposed.13:45
xnoxdo we need a broken kernel in artful-proposed, if it is not passing adt tests?13:45
apwwhat is it blocking whihc is such a huge pressure ?13:45
xnoxit's not like it will magically pass, due to changes needed in either kernel or the test-suite? thus that upload is toast, no?13:45
apwif you say gcc i will punch you on the nose13:45
xnoxit's blocking automated migration.13:45
xnoxsystemd13:45
xnoxgcc for doko; systemd for me. As usual.13:46
apwok so we can hint systemd if that is the only failure13:46
apwthat is why we have hints13:46
xnoxapw, but hinting requires humans.13:46
xnoxi'd rather just remove the src:linux from artful-proposed.13:46
xnoxrather than badtesting src:linux.13:46
apwand you will expect me to not do the same for systemd if it fails for an instant right ?13:46
smband that does not require a human?13:47
xnoxthe test is good; and that src:linux is genuenly toast, no?13:47
apwsmb, the same humans indeed13:47
xnoxapw, i expect an upload to fix the systemd in proposed or remove the offending systemd in proposed.13:48
apwxnox, indeed, and we are working on that right now13:48
xnoxobviously we cannot remove src:linux or src:systemd from artful-release.13:48
xnoxhm it is very odd.13:49
apwwhat is very odd13:49
xnoxi see test results for 6.11 and 7.12, but not 8.13 and release pocket has 4.10.0-22.2413:49
xnoxe.g. systemd migration should be tested against 4.10, not 4.1113:49
apwxnox, yes, if it is not that is a failure in adt13:50
apwor some muppet ran all-proposed run13:50
apwwe should remove that option13:51
xnoxkernel adt tests are odd; they mostly test the new kernel; and very little test of changed userspace.13:51
xnoxapw, but do you run adt tests of linux kernel against the new kernel after it is built in the kernel PPA before copying into the devel-proposed?13:52
apwxnox, normally yes, unsure if that was done for this one as this was a fix for an emergency CVE13:53
xnoxbecause 5.10, 6.11, 7.12, 8.13 of the 4.11 are all failing13:53
apwxnox, but as the only people who should be afected are us13:53
xnoxtrue.13:53
apwxnox, as they are only in -proposed and your testing is against -release13:53
apwxnox, so perhaps we need to work out how you got tests against the -proposed version at all13:53
xnoxyes.13:54
xnoxmeanwhile i'm doing self service request to rerun systemd->linux against release linux, rather than proposed linux.13:55
