[03:38] <CreateChange> hello, where can i find an actual list of snap packages
[03:38] <CreateChange> i am struggling to that end
[06:02] <zyga-ubuntu> good morning
[06:07] <mvo> hey zyga-ubuntu
[06:14] <mvo> zyga-ubuntu: hrm, hrm, looks like we need 2.28.2 and pull in #4004 (nice number). I didn't see this pr and I'm not sure I would have spotted the significance. did we improve the validation in 2.28 or why did it start breaking suddenly?
[06:14] <mup> PR #4004: interfaces/lxd: lxd slot implementation can also be an app snap <Created by jdstrand> <Merged by zyga> <https://github.com/snapcore/snapd/pull/4004>
[06:16] <zyga-ubuntu> mvo: hello, I think this is lxd on core (not classic) and we never touched this
[06:16] <zyga-ubuntu> mvo: so lxd-as-a-snap vs lxd slot provided by core
[06:16] <zyga-ubuntu> mvo: I think it was never working but perhaps my assumptions are wrong
[06:17] <zyga-ubuntu> mvo: and it looks untested, maybe we test it in the nightly "important snaps work" thing but I didn't check yet
[06:18] <zyga-ubuntu> mvo: although, the wording "stopped working" in the lxd bug report seems to imply improved validation
[06:19] <mvo> zyga-ubuntu: yeah, stgraber indicated it is a regression - anyways, I am fixing now but would love to understand better why we see it now, maybe pawel knows
[06:21] <zyga-ubuntu> mvo: as far as I understand it interface validation never prevented snaps from refreshing (we juts logged it) and while this has changed rencently it's not 2.28 material
[06:22] <mvo> zyga-ubuntu: yeah, its not the refresh, its the connection that is no longer working for him
[06:51] <zyga-ubuntu> mvo: hmm, on Ubuntu 14.04 we only have 2.27.5 available, why is that?
[06:51] <zyga-ubuntu> mvo: I was trying to understand a failure in 2.27.6 when installed on 14.04
[06:52] <zyga-ubuntu> mvo: it would fail with Failed to enable unit: File snapd.refresh.timer: No such file or directory
[06:54] <mvo> zyga-ubuntu: 2.27.6 should be in proposed, also via core re-exec
[06:54] <mvo> zyga-ubuntu: what failure on trusty is that, is there a forum post?
[07:03] <zyga-ubuntu> mvo: it's this bug https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1722075

[07:07] <mvo> zyga-ubuntu: is it 2.28.3 material? i.e. should I hold back this release?
[07:09] <zyga-ubuntu> mvo: no, I think it's not meant to work
[07:09] <zyga-ubuntu> mvo: but I'm still looking
[07:10] <zyga-ubuntu> mvo: 17.04 system (upgrade from 16.10) with 14.04 package

[07:17] <mwhudson> __chip__: my snapcraft pr is only about half way down the list, they must be slacker than you guys :)
[07:17] <mwhudson> zyga-ubuntu: so um i guess we should package 2.28.2 for debian?
[07:20] <zyga-ubuntu> mwhudson: yes, I think so
[07:20] <zyga-ubuntu> mwhudson: btw, interesting observation
[07:20] <zyga-ubuntu> mwhudson: recent 9.2 stable release of debian had brand new flatpak
[07:20] <zyga-ubuntu> mwhudson: perhaps we could do the same
[07:20] <mwhudson> zyga-ubuntu: good thing i don't have anything at all to do between now and artful release, eh?
[07:20] <mwhudson> zyga-ubuntu: hmm
[07:21] <mwhudson> zyga-ubuntu: although 2.28 should work ok via reexec thanks to the graceful apparmor stuff you did
[07:21] <zyga-ubuntu> mwhudson: I need to fix my VM box (reinstall the OS on new drive and then copy data over)
[07:21] <zyga-ubuntu> mwhudson: yep but we could try to get it into 9.3, if there is one
[07:21] <zyga-ubuntu> mwhudson: we could pick the right stable release and go along with it
[07:22] <mwhudson> yeah that'd be good
[07:24] <zyga-ubuntu> hmm, has the new snap pack landed?

[10:19] <ackk> it seems my snap is not able to resolve hostnames, but it has the 'network' interface (and it's connected). how can I debug what's going on?

[10:31] <kalikiana> ackk: I find running it in devmode helpful in case something's being blocked by apparmor because you'll get log messages
[10:31] <ackk> kalikiana, so, it seems it's trying to access stuff under hostfs, like resolv.conf or os-release
[10:31] <ackk> but it shouldn't really need that
[10:32] <ackk> I mean, having the "network" plug it should have connectivity?
[10:32] <popey> As a user, I have a snap which I think broke in 2.28. To confirm, how do I easily go back to core 2.27?
[10:35] <kalikiana> popey: `snap revert` gets you back to the previous revision, you can also do `snap revert core --revision=2925` for a specific one, but afair it must be one of the last three you had on your system

[10:35] <popey> works on my intel laptop
[10:35] <popey> it _used_ to work
[10:35] <popey> I am trying to figure out if hiri broke their snap or we did
[10:36] <kalikiana> ackk: Yes. Probably something's trying to be smart. Although /etc/os-release should be accessible just fine, other things may be blocked
[10:36] <zyga-ubuntu> popey: can you show any apparmor denials
[10:37] <zyga-ubuntu> popey: and confirm that it works on 2.27.x
[10:37] <popey> uh

[10:37] <zyga-ubuntu> popey: also can you run hiri from command line with SNAP_CONFINE_DEBUG=yes
[10:37] <popey> I asked how I can go back to 2.27 :D

[10:40] <kalikiana> ackk: does lxd have no network? if that's the case you might want to `snap disable lxd; snap enable lxd`. I've seen it some time ago and that was my work-around
[10:41] <zyga-ubuntu> popey: can you please help me out
[10:41] <zyga-ubuntu> popey: I need you to do this:
[10:41] <kalikiana> ackk: and, put those logs in a bug report ideally

[10:42] <ackk> kalikiana, disable/enable didn't work

[10:43] <popey> kk
[10:43] <kalikiana> ackk: I'm not following... `lxc` is just the command line tool of lxd. What exactly is not working?
[10:43] <ackk> kalikiana, if I run lxc image list ubuntu:
[10:44] <zyga-ubuntu> popey: snap-confine should never access /sys/module/nvidia_modeset/uevent so I'm curious what is going on
[10:44] <ackk> kalikiana, that fetches the simplestreams index from the image server. that fails
[10:44] <zyga-ubuntu> popey: also paste snap version here (I only care about the distrO)
[10:44] <ackk> kalikiana, a curl of the same url from cmdline of course works

[11:16] <zyga-ubuntu> it's just a file name

[11:20] <Chipaca> popey: don't forget to stand on the _left_ side of your _right_ foot while reverting, and the order is: adopt stance, start whistling tune, execute commands, leave stance, stop whistling

[11:25] <zyga-ubuntu> flexiondotorg: interesting!
[11:25] <popey> Ok, hiri now works fine atfer rolling back to 2.27
[11:25] <zyga-ubuntu> popey: try hhir now
[11:25] <zyga-ubuntu> popey: ok
[11:25] <zyga-ubuntu> popey: please do this:
[11:25] <zyga-ubuntu> popey: send me all the apparmor profiles from /etc/apparmor.d/snap.core.*.usr.lib.snapd.snap-confine
[11:27] <popey> zyga-ubuntu: sent
[11:28] <popey> (email)
[11:28] <zyga-solus> thanks
[11:28] <zyga-solus> let me look
[11:28]  * zyga-solus walks between kitchen and office
[11:30] <zyga-ubuntu> popey: ok so the working one is 2898
[11:30]  * zyga-ubuntu looks
[11:33] <zyga-ubuntu> popey: it makes no sense :/ it looks like the new profile is more forgiving actually
[11:36] <popey> zyga-ubuntu: we have confirmed that this is also the case with a completely different snap, on another nvidia machine which is 17.10
[11:36] <popey> reverting to core 2898 made the snap work there too.
[11:36] <zyga-solus> popey: it looks like nvidia is affected in general
[11:36] <popey> also an opengl snap
[11:36] <zyga-solus> not specific to hiri
[11:36] <popey> yes
[11:36] <zyga-solus> now would be a good time for me to have easy way to use nvidia :/
[11:36] <zyga-solus> (which I don't)
[11:36] <popey> This is not the first time this problem has bitten us.
[11:37] <zyga-solus> I understand, we don't have any testing of nvidia AFAIK
[11:37] <popey> Indeed, wasn't pointed at you. It's common across the company.
[11:37] <zyga-solus> I meant me for debugging, I think we need to fix our release process to include simple "works / not works" opengl testing on intel, nvidia and amd GPUs
[11:38] <popey> I happen to be lucky enough to have two laptops side by side, nvidia and intel, so pick this stuff up. Not everyone has that luxury
[11:38] <zyga-solus> or just nvidia for a start
[11:38] <zyga-solus> popey: I have 3 but all intel
[11:38] <popey> I understand you can spin up a machine in AWS with a GPU
[11:38] <popey> There's your problem :)
[11:38] <zyga-solus> popey: with ubuntu kernel?
[11:38] <popey> Hm, good question. I am not sure.
[11:38] <zyga-solus> probably not
[11:38]  * zyga-solus looks on ebay
[11:39] <popey> separately, will I be stuck on rev 2898 now I reverted to it?
[11:39] <popey> or will the next update push me forward again?
[11:40] <zyga-solus> popey: not sure, I think refresh vs revert but not sure if this is implemented
[11:41] <popey> Shall I file a bug in snapd for this?
[11:41] <popey> Feels somewhat critical
[11:41] <zyga-solus> popey: no, the forum thread is enough
[11:41] <popey> ok
[11:45] <popey> zyga-solus: do you need remote access to an nvidia machine (I have a desktop here I can slap 16.04 on)?
[11:45] <zyga-solus> popey: that wold help
[11:46] <popey> lemme dig it out, one mo
[11:46] <zyga-solus> popey: thank you
[11:47] <zyga-ubuntu> mvo: what is the status of your nvidia box?
[11:47] <zyga-ubuntu> mvo: I have a laptop but unused, I could try to boot it from live media or maybe swap HDD and install that way (it's not used by me and has other os)
[11:47] <mvo> zyga-ubuntu: I have a nvidia card somewhere I don't use it usually, but I can plug it in
[11:48] <zyga-ubuntu> mvo: if that fails I'll try to install ubuntu on mine
[11:49] <mvo> zyga-ubuntu: let me try to find it, any opengl game will do?
[11:49] <zyga-solus> mvo: yes
[11:49] <zyga-solus> mvo: or just try hiri
[11:50] <mvo> zyga-ubuntu: what did change in this area recently? could it be snap-confine?
[11:50] <zyga-solus> mvo: I was looking at the diff between the snap-confine profiles and we did change various things for how the lib directory is called in solus and elsewhere
[11:50] <zyga-solus> mvo: but we never ever touch the file we get the denial on
[11:50] <zyga-solus> mvo: so I think something else may be broken
[11:51] <zyga-solus> mvo: and we just see the weird side effect
[11:51] <mvo> zyga-solus: I see  - I wonder how we can test this in an integration test
[11:51] <zyga-solus> mvo: modprobe nvidia (maybe) if it sticks
[11:51] <mvo> zyga-ubuntu: what file gets the denials
[11:52] <zyga-solus>  [ 2879.277628] audit: type=1400 audit(1507710260.432:1680): apparmor=“DENIED” operation=“open” profile="/snap/core/3017/usr/lib/snapd/snap-confine" name="/sys/bus/pci/drivers/nvidia/uevent" pid=13789 comm=“snap-confine” requested_mask=“r” denied_mask=“r” fsuid=0 ouid=0
[11:53] <zyga-solus> not sure how this happens
[11:53] <zyga-solus> hold on, I think I know
[11:54] <zyga-solus> jdstrand said that nvidia is not in sysfs the regular way and added a hack for supporting udev tagging, remember?
[11:54] <zyga-solus> one sec

[11:56] <zyga-solus> mvo: it is this patch
[11:56] <mvo> zyga-solus: strange that denial, I add the card now, bbiab (need to open the machine etc)
[11:56]  * Chipaca needs to reboot, brb
[11:56] <zyga-solus> k
[11:57] <zyga-solus> mvo: I'm making a patch
[11:59] <zyga-solus> popey: still there?
[11:59] <zyga-solus> popey: refresh to stable again
[11:59] <popey> ok
[11:59] <zyga-solus> popey: and edit the profile in /etc/apparmor.d/
[12:00] <zyga-solus> popey: the one for snap-confine on revision 3017 (if I recall correctly)
[12:00] <zyga-solus> anyway, the latest one
[12:01] <zyga-solus> popey: ls /sys/bus/pci/drivers/nvidia/
[12:02] <zyga-solus> popey: in the file you are editing go to line 6 (so inside the { } spanning the whole file)
[12:02] <zyga-solus> popey: and add this line(s) (waiting for your ls output)
[12:03] <zyga-solus> popey: /sys/bus/pci/drivers/nvidia/uevent r,
[12:03] <zyga-solus> popey: then save the file and use "apparmor_parser -r /etc/apparmor.d/snap.core.3017.usr.lib.snapd.snap-confine" to re-load
[12:03] <zyga-solus> popey: then start hiri again
[12:03] <popey> ok. took a while to get to refresh core. updated now
[12:03] <zyga-ubuntu> popey: thank you
[12:05] <popey> alan@hal:~$ ls /sys/bus/pci/drivers/nvidia/

[12:05] <zyga-ubuntu> ok
[12:06] <zyga-ubuntu> add the uevent line as I said, reload the profile and start hiri
[12:06] <zyga-ubuntu> we'll iterate till it works
[12:06] <popey> ok
[12:06] <popey> so added that one uevent r line
[12:07] <popey> hiri still core dumps

[12:09] <zyga-solus> nothing else? can you connect the mount interfaces
[12:09]  * ogra_ sets +q on popeybot
[12:09] <ogra_> :P
[12:09] <zyga-solus> or try a some simple opengl snap/
[12:10] <popey> i have another gl one that broke
[12:10] <popey> https://www.irccloud.com/pastebin/saHHCGu4/

[12:10] <ogra_> heh
[12:11] <popey> https://www.irccloud.com/pastebin/1NEBw33c/
[12:11] <popey> and another
[12:11] <ogra_> you can ignoe inet6
[12:11] <zyga-ubuntu> popey: works?
[12:11] <popey> no
[12:11] <popey> all broken

[12:12] <ogra_> (and we shoudl really quieten it, they should not be printed if there is no v6 network configured)
[12:12] <zyga-ubuntu> ok
[12:12] <mvo> zyga-solus: \o/ for making a patch, let me know once I can test something
[12:12] <zyga-ubuntu> mvo: still at the /o\ stage, I need to wrap my head around this, I assumed a simple tweak would do but I think we tag things incorrectly somewhere and there are devices missing in the namespace
[12:13] <zyga-ubuntu> mvo: so no patch yet
[12:18] <zyga-solus> popey: can you try a richer patch please

[12:19] <zyga-solus> popey: then restart hiri
[12:19] <Chipaca> what was the generic name, on the phone, of things that mediated access to things? like the file manager
[12:19] <zyga-solus> Chipaca: media hub
[12:19] <ogra_> Chipaca, content-hub
[12:19] <popey> ok
[12:19] <zyga-solus> ah
[12:19] <zyga-solus> sorry :)
[12:20] <ogra_> but media-hub was clöose enough ;) (same thing. just for media files)
[12:20] <Chipaca> right, the content hub was one of them, wasn't there a name for all of them?
[12:20] <zyga-solus> trusted helper?
[12:20] <ogra_> trusted helper was the equivalent to snap intefaces
[12:20] <zyga-solus> well, not really
[12:21] <zyga-solus> we will use trusted helpers in snapd (we already use some)
[12:21] <popey> still broken..
[12:21] <ogra_> (to allow direct accesds to bits ... like location or so)
[12:21] <zyga-solus> anyway, distraction
[12:21] <zyga-solus> popey: any denials?
[12:21] <zyga-solus> did you reload the profile?
[12:21] <zyga-solus> popey: try discarding the namespace (just to be sure, I don't think we need to)
[12:21] <popey> http://paste.ubuntu.com/25719780/
[12:21] <popey> i did reload the profile
[12:22] <popey> ^ me running hiri, goxel and ohmygiraffe
[12:23] <popey> tried discarding namespace too, also fails
[12:25] <zyga-solus> popey: go to /sys/fs/cgroup/devices
[12:26] <zyga-solus> popey: what do you have there
[12:27] <popey> lots of files, anything in particular you're interested in?
[12:27] <zyga-solus> popey: snap.*
[12:27] <popey> http://paste.ubuntu.com/25719806/
[12:28] <zyga-solus> great
[12:28] <zyga-solus> go to hiri
[12:28] <zyga-solus> then show devices.allow please
[12:30] <popey> it's an empty file

[12:30] <popey> cat: devices.allow: Invalid argument
[12:31] <zyga-solus> aww, drat
[12:31] <zyga-solus> ok, one sec
[12:31] <zyga-solus> darn
[12:31] <zyga-solus> we don't log that
[12:31] <zyga-solus> so
[12:31] <zyga-solus> it's the oldest part of snap-confine
[12:31] <zyga-solus> and one I barley touched
[12:31] <zyga-solus> so it doesn't log anything useful
[12:33] <zyga-solus> I'm afraid we need some build/edit cycles
[12:34] <Chipaca> is this something breaking in 2.28, or is it broken before that?
[12:34] <popey> am installing 17.10 on an nvidia machine here for you if that helps
[12:34] <zyga-solus> Chipaca: 2.28
[12:34] <Chipaca> zyga-solus: is it a blocker?
[12:34] <zyga-solus> popey: yes, very much
[12:34] <zyga-solus> Chipaca: yes
[12:34] <Chipaca> zyga-solus: am I sad?
[12:34]  * Chipaca is sad
[12:35] <Chipaca> popey: thank you for spotting it though
[12:35] <popey> np
[12:35] <Chipaca> zyga-solus: what aren't we testing?
[12:35] <Chipaca> do we need to have an nvidia 16.04 box as part of qa?
[12:36] <zyga-solus> Chipaca: absolutely
[12:36] <Chipaca> ok
[12:36] <Chipaca> how do we do this?
[12:38] <zyga-solus> Chipaca: I'd just make sure that cachio has a nvidia box to test on
[12:39] <zyga-solus> Chipaca: and then try external target
[12:39] <Chipaca> cachio: you're about to become a gamer dude
[12:39] <zyga-solus> Chipaca: and ensure we run opengl snaps as a part of that
[12:39] <Chipaca> :-D
[12:39] <popey> (don't forget AMD) :)
[12:39]  * Chipaca forgets AMD because it sucks
[12:39]  * Chipaca looks for a fight
[12:39] <zyga-solus> popey: we have no amd-specific code
[12:39] <popey> shocked emoji
[12:39]  * Chipaca stops looking for a fight and starts looking for tea
[12:39]  * zyga-solus is starving, I need to break for food now
[12:46] <mvo> zyga-solus: took a little bit, had to tweaks various things in artful and had the wrong nvidia driver (how is a user supposed to know twhich of nvidia-NNN he/she needs?). anyways, I can test things now too
[12:47] <zyga-ubuntu> mvo: I think the driver package makes that
[12:47] <zyga-ubuntu> mvo: did you install the proprietary driver?
[12:48]  * kalikiana moving to a coffee shop, back in a bit
[12:48] <zyga-ubuntu> mvo: I'd like to know which devices are in the cgroup
[12:49] <zyga-ubuntu> popey: can you cat devices.list
[12:49] <zyga-ubuntu> popey: on your existing machine
[12:49] <popey> yes
[12:49] <popey> http://paste.ubuntu.com/25719909/
[12:50] <zyga-ubuntu> popey: so
[12:50] <zyga-ubuntu> popey: it looks like we don't do nvidia part correctly
[12:51] <zyga-ubuntu> nvidia is 195
[12:51] <zyga-ubuntu> I'll update the forum
[12:55] <zyga-ubuntu> popey: what do you have in "ls -l /dev/nvidia*"
[12:55] <zyga-ubuntu> popey: we may be able to test a fix on your system with some shell

[12:55] <popey> pm...
[12:58] <zyga-ubuntu> popey: ok, let me ssh in and play,
[12:58] <zyga-ubuntu> popey: but I see what is broken
[12:58] <zyga-ubuntu> not sure why yet
[12:58] <popey> kk

[13:07] <tai271828> hi, question: do we have kernel snap that is corresponding to "proposed kernel"? especially for pi2 kernel.   may anyone know and please tell me the answer? (googled "pi2 kernel snap" and I think the answer is "no")
[13:08] <ogra_> tai271828, proposed as in the proposed deb archive ?
[13:08] <tai271828> ogra_: yes, and I just found this https://launchpad.net/pi2-kernel-snap
[13:08] <ogra_> tai271828, the beta and candidate channels get uploads in sync with the proposed deb
[13:09] <tai271828> ogra_: hmmm, cool, then I must misunderstand something, thanks for clarifying
[13:09] <tai271828> ogra_: thanks!
[13:11] <ogra_> tai271828, note that the pi2 kernel in stable is actually stuck due to the missing ability to upgrade gadgets on devices ... typically the snaps woould move on from beta/candidate to stable (but without working gadget upgades they wouldnt boot, the binary blobs are to old in the stable gadget currently)
[13:12] <tai271828> ogra_: got it, thanks for the useful information.
[13:12] <ogra_> :)

[13:41] <slangasek> hi, what has changed between core snap 2898 and core snap 3017?  Because this has broken the subiquity server image, /var/lib/snapd/seed doesn't seem to get processed correctly at boot and so subiquity doesn't start
[13:42] <mvo> slangasek: there were quite a few changes, do you have more details in what way things break? what can I do to reproduce?
[13:43] <slangasek> mvo: you can download and boot http://cdimage.ubuntu.com/ubuntu-server/daily-live/current/artful-live-amd64.iso
[13:43] <mvo> slangasek: thanks, downloading now
[13:43] <slangasek> mvo: the only thing visible in the systemd journal is that snap-confine can't find libudev.so.1
[13:45] <mvo> slangasek: any denials in dmesg?
[13:45] <ogra_> mvo, systemd from the PPA out of sync with the distro llibudev ?
[13:45] <slangasek> mvo: apparmor="DENIED" on /rofs/etc/ld.so.cache
[13:46] <ogra_> wow, where would /rofs come from ?
[13:46] <slangasek> it's a live image
[13:46] <ogra_> ah
[13:46] <slangasek> so root is an overlayfs + squashfs
[13:46] <slangasek> and the real path is not the apparent path
[13:46] <slangasek> so I guess one of the changes was to confine snap-confine itself?
[13:47] <slangasek> mwhudson: ^^ so, that's what's going on with the latest image
[13:47] <mvo> slangasek: we always had snap-confine confined
[13:48] <ogra_> we do have a patch to systemd in the PPA that makes the core snap have a differentlly versioned libudev package thoough
[13:49] <ogra_> mvo, that should have gone into a live-build hook instead i guess
[13:50] <ogra_> (til the actual systemd SRU lands)
[13:50] <slangasek> oh
[13:50] <ogra_> https://launchpad.net/~snappy-dev/+archive/ubuntu/image/+packages?field.name_filter=&field.status_filter=published&field.series_filter=xenial
[13:50] <slangasek> indeed, there's also a denial for /rofs/lib/x86_64-linux-gnu/libudev.so.1.6.6
[13:50] <slangasek> which is probably the real one
[13:53] <slangasek> so, should we be extending the apparmor profile to account for /rofs as a special case?
[13:53] <ogra_> given that the fix is actually something that should rather live in /etc/sysctl.d, we shoulld probably just rework it to come either via a llive-build hook or via ubuntu-coe-config
[13:53] <ogra_> oh
[13:53] <ogra_> that perhaps as well :)

[13:56] <ogra_> ah, right
[13:56] <slangasek> mvo, ogra_: does removing this systemd package from the ppa relate to the apparmor denials, or something else?
[13:57] <ogra_> slangasek, just to "out of sync with the archive regarding versioning" ... i think the denial actually requires the addition oof /rofs
[13:57] <slangasek> ok
[13:57] <slangasek> I'll chase jdstrand in person, thanks :)
[14:02] <mvo> slangasek: what I wonder about is why this worked before. we always had an apparmor profile around snap-confine and never allowed /ro
[14:03] <ikey> ok further to my slightly skewiff snapcraft forum post, i need to create a snap without a core dependency, and apparently "bare" is the way for this. are any ubuntuisms expected of my snap, and is it possible for me to properly have my /lib64 /usr/lib64 /usr/bin etc directories present in my snap?

[14:06] <jdstrand> mvo: slangasek tracked me down. I suspect that the compiler options changed and libudev isn't being linked in statically
[14:07] <ikey> i want to make a decent steam snap and ironically that means not using ubuntu for the base of it, hence the query..
[14:07] <jdstrand> mvo: I have a vague recollection that zyga touched this semi-recently (I could be wrong). We have traditionally statically linked in libseccomp and libcap (and honestly, libudev). not sure why this would've changed...

[14:10] <slangasek> jdstrand: fwiw I just checked, and linkage of snap-confine is not different between the two images
[14:11] <slangasek> although, do I need to look at snap-confine within the core snap itself?

[14:11] <jdstrand> mvo (cc slangasek): however, I wouldn't expect snaps to work *today* on a live session, so this isn't a regression, is it?
[14:12] <jdstrand> slangasek: you would need to look in core, yes
[14:12] <jdstrand> (cause eof reexec)
[14:12] <slangasek> jdstrand: looked inside core_2898; snap-confine in there is also dynamically linked against libudev
[14:12] <zyga-solus> popey: is hiri running?
[14:12] <popey> no
[14:13] <slangasek> jdstrand: and this is a regression for subiquity specifically, which somehow *did* work before the core update, even if other snaps apparently do not
[14:13] <popey> zyga-ubuntu:
[14:13] <popey> its slowly loading
[14:13] <slangasek> jdstrand: (we had it working in the 17.04 image, and it was working in artful dev until today)
[14:13] <zyga-solus> ah
[14:13] <popey> yes, i see hiri now
[14:13] <zyga-solus> popey: wooot
[14:13] <zyga-solus> popey: so we have a fix
[14:13] <popey> yay
[14:13] <jdstrand> slangasek: I wonder why subiquity is (now?) using a snap...
[14:13] <jdstrand> I mean, why is snap-confine running at all?
[14:14] <jdstrand> cause, if we fixed this issue and made snap-confine be happy, it'll then launch something that will be sad (if in strict mode)
[14:14] <slangasek> jdstrand: that is also not new - it was a) let us move faster with subiquity during release freeze, b) dogfood snaps, c) make subiquity something that anyone can download into a maas ephemeral environment
[14:15] <slangasek> it's a classic snap, not strict
[14:15] <jdstrand> ok. I find this quite curious. what happens if you allow /rofs/etc/ld.so.cache?
[14:15] <jdstrand> I guess you just need read?
[14:16] <slangasek> I expect so
[14:16] <slangasek> allow it> by editing the apparmor profile in the live env?
[14:16] <jdstrand> slangasek: yes
[14:17] <jdstrand> grab the profile that corresponds to the core snap
[14:18] <jdstrand> slangasek: use snap list to get the revision of core. then edir /etc/apparmor.d/snap.core.<rev>.usr.lib.snapd.snap-confine
[14:19] <jdstrand> slangasek: if that is ro, just cp /snap/core/current/etc/apparmod.d/usr.lib.snapd.snap-confine
[14:20] <jdstrand> slangasek: then modify and load that copy
[14:20] <slangasek> jdstrand: well, thus far 'snap list' says nothing, because things fail early enough that the seed is never fully processed AFAICS.  But yeah, I'll dig, thanks
[14:21] <jdstrand> zyga-solus: fyi, rofs might actually be a future consideration for snap-confine.d (ie, snapd detects it is in a live image, adds some policy)
[14:21] <jdstrand> zyga-solus: all future, nothing to do now

[14:32] <mvo> jdstrand: what shall we do about the /ro issue from slangasek? add support for that too?
[14:33] <mvo> jdstrand: I'm still puzzled how this evar worked?
[14:33] <slangasek> jdstrand: so if I edit the profile under /etc/apparmor.d, apparmor_parser -r, and systemctl restart snapd, snapd overwrites the profile again and loads the original
[14:34] <slangasek> jdstrand: so I'm not sure how I should test the result
[14:35] <jdstrand> mvo: fyi, I recommended even better future-proofed rules
[14:35] <mvo> jdstrand: in 4022? yeah, +1 for that
[14:35] <mvo> slangasek: please don't restart snapd, it should be fine without a restart
[14:35] <jdstrand> mvo: re 4022> note, I recommended one set, and 3 seconds ago recommended a better set
[14:35] <slangasek> mvo: so what should I do in order to test?
[14:35] <mvo> slangasek: and yes, on restart it will rewrite the rules, it is very opionated about that
[14:35] <slangasek> all the snaps get unmounted
[14:35] <mvo> jdstrand: heh, ok
[14:35] <jdstrand> mvo: I'm puzzled too
[14:36] <jdstrand> slangasek: the test is, load the profile and don't restart snapd
[14:36] <mvo> slangasek: uh, you need to restart snapd so that it applies the seed, right?
[14:36] <slangasek> jdstrand: ok but then what?
[14:36] <jdstrand> slangasek: then launch whatever subiquty is doing
[14:36] <slangasek> what subiquity is doing is running the bits from the snaps, that are not mounted, because snap-confine failed and things were rolled back :)
[14:36] <mvo> slangasek: what changes did jdstrand suggest?
[14:36] <jdstrand> that is a fun spelling
[14:36] <ackk> kalikiana, so it seems that adding the network slot to the lxc app actually makes it not work with network :)
[14:36] <ackk> quite odd
[14:37] <slangasek> mvo: adding /rofs/etc/ld.so.cache as a test
[14:37] <jdstrand> mvo: an r rule for the /rofs/ ld.so.cache
[14:37] <jdstrand> (that isnt the full path
[14:37] <jdstrand> )
[14:37] <mvo> slangasek: ta, I can try that and snap install /var/lib/snapd/seed/snaps/* manually
[14:37] <jdstrand> man, irc is *laggy*...
[14:37] <slangasek> ah, testing that here as well
[14:38] <jdstrand> yes, snap install  a classic snap
[14:38] <slangasek> apparmor profile overwritten again
[14:38] <jdstrand> then run snap run --shell snap.command
[14:38] <jdstrand> that is enough to get snap-confine going
[14:38] <slangasek> but this time the core snap has stayed mounted
[14:38] <zyga-ubuntu> popey: is the giraffe still around?
[14:39] <popey> yes
[14:39] <slangasek> jdstrand: I see apparmor denials for both ld.so.cache and libudev
[14:39] <zyga-ubuntu> jdstrand: where did you push it?
[14:39] <jdstrand> zyga-ubuntu: I haven't pushed anything
[14:39] <zyga-ubuntu> ah sorry
[14:40] <jdstrand> slangasek: I suggest copying the fileand loading that
[14:40] <jdstrand> snapd shouldn't rewrite the file and load it then (and if it does, at least your changes aren't overwritten, you need only reload)
[14:41] <slangasek> jdstrand: oh, because the file doesn't have to have the same name as the path?  hurr ok
[14:41] <jdstrand> yes
[14:42] <jdstrand> slangasek: it is the contents of the file that matter. the filename is just convention
[14:43] <slangasek> jdstrand: ok.  I have to add rofs for both libudev and ld.so.cache, and then I get farther... and then we get the same error for libpthread.so.0
[14:43] <jdstrand> mvo: I'm curious. with 4022, with only the code changes, the apparmor rules are required?
[14:43] <slangasek> jdstrand: why are the libs from the rootfs being used instead of those inside the snap?
[14:43] <slangasek> isn't that the real issue here?
[14:43] <mvo> jdstrand: I am not sure if they are strictly required, I had some denials when testing hiri
[14:43] <popey> zyga-ubuntu: giraffe is back!
[14:44] <zyga-ubuntu> popey: great
[14:44] <zyga-ubuntu> popey: so it works
[14:44] <zyga-ubuntu> I'll close the window now, that's all I need
[14:45] <zyga-ubuntu> popey: thank you very very much
[14:45] <jdstrand> slangasek: I think what was maybe happening before is that snapd was considering the live session as "not Ubuntu' and running snapd in non-restrictive mode
[14:45] <jdstrand> mvo: does that sound plausible? ^
[14:45] <popey> zyga-ubuntu: np, shall I shut this down now?
[14:45] <mvo> jdstrand: let me check os-release
[14:45] <zyga-ubuntu> popey: yes, I think it's good now
[14:45] <popey> kk
[14:46] <zyga-ubuntu> popey: just label it "zyga" and put it on the shelf ^_^
[14:46] <zyga-ubuntu> (kiddin)
[14:46] <popey> was about to ask :D
[14:46] <jdstrand> (and snap-cofine's profile wasn't loaded and between the two, things worked cause snap-confine wasn't confined)
[14:46] <mvo> jdstrand, slangasek: fwiw, I added /rofs/a-bunch-of-libs, now it fails on /vow/upper/var/lib/snapd/cookie
[14:46] <jdstrand> yeah, this is exactly the road I was talking to slangasek about running snaps in t he live image the other day
[14:46] <jdstrand> we aren't gong to fix this whack-a-mole
[14:47] <jdstrand> we need the previous behavior when on live session
[14:47] <jdstrand> snap-cofine should not be confined and snapd needs to be cool with that
[14:47] <mvo> jdstrand: well, os-release says ID=ubuntu so previous versions *should* have confined it too
[14:48] <mvo> jdstrand: but obviously reality disagrees with me
[14:48] <zyga-ubuntu> jdstrand: aha
[14:48] <jdstrand> this is indeed puzzling
[14:48] <zyga-ubuntu> jdstrand: by sayin "shoud not be confined" do you mean that in live sessions we should unload the profile
[14:48] <slangasek> previous working image still available at http://cdimage.ubuntu.com/ubuntu-server/daily-live/20171010.1/artful-live-amd64.iso for comparison
[14:48] <zyga-ubuntu> jdstrand: or just disable apparmor in the kernel?
[14:48] <jdstrand> oh
[14:48] <jdstrand> yes
[14:49] <jdstrand> slangasek: I thought for live fs there was something about detecting if apparmor was there and not using it
[14:49] <jdstrand> passing apparmor=0
[14:49] <jdstrand> something in the init script
[14:49] <slangasek> oh?  let me see
[14:50] <slangasek> I don't find any references to that in livecd-rootfs
[14:50] <jdstrand> something... (I can't recall the details)
[14:50] <slangasek> a userspace process is allowed to disable apparmor after boot?
[14:51] <mvo> jdstrand: that sounds very plausible to me, if apparmor is disabled we detect that and things should work
[14:53] <kalikiana> ackk: Interesting. Not what I would've expected...
[14:53] <jdstrand> ah
[14:54] <jdstrand> mvo, slangasek: I bet what is happening is that the apparmor initscript is not loading /etc/apparmor.d. *but* snapd is reexcing and loading snap-confine's profile
[14:54] <jdstrand> mvo, slangasek: so napd needs to detect if on live session and not do that
[14:55] <jdstrand> slangasek: disable apparmor after boot> no. userspace can choose to not load profiles though
[14:56] <jdstrand> mvo: fyi, /lib/apparmor/functions /profile-load has: [ -d /rofs/etc/apparmor.d ]  && exit 0 # do not load if running liveCD
[14:56] <jdstrand> I gotta run
[14:56] <slangasek> test -d /rofs/etc/apparmor.d && exit 0
[14:57] <slangasek> that's in the apparmor init script

[15:02] <mvo> slangasek, jdstrand: on reboot it works now
[15:03] <jdstrand> mvo: so, reexec for snap-confine is loading the appropriate profile into the kernel. it shouldn't on livefs (see reference from me and slangasek, above)
[15:04] <jdstrand> mvo: in the reexec code, just looke for /rofs/etc/apparmor.d and don't load
[15:04] <jdstrand> that should immediately fix this issue

[15:04] <jdstrand> I can't comment on when it was first introduced
[15:04] <jdstrand> (the regression)
[15:05] <jdstrand> . we've had reexec for ages, so not sure what it is showing up only now

[15:05] <jdstrand> ogra_: that would be simple. I don't know the requirements for livefs

[15:08] <mvo> ogra_: interessting - jdstrand, what do you think about about "<ogra_> mvo, just addint SNAP_REXEC=0 to casper defaults would do"?
[15:09] <kalikiana> elopio: Did you run it more than once with the same container while testing? If you do a cleanbuild you won't see a difference
[15:09] <elopio> kalikiana: so, I don't understand why it knows that the core snap is the same and doesn't reinstall it, but it doesn't work the same way for the snapcraft snap and it is reinstalled?
[15:10] <jdstrand> mvo: I think that is very reasonable
[15:10] <jdstrand> I suspect you can test that right now
[15:10] <elopio> kalikiana: Sergio said it's because core comes from the store, and the snapcraft snap is a --dangerous install. But if we are checking the .snap, I don't understand that difference.
[15:11] <jdstrand> I forget how casper works otoh
[15:11] <kalikiana> elopio: Was the snapcraft snap the same? From your comment I can't tell

[15:11] <jdstrand> mvo: yes
[15:11] <kalikiana> elopio: it should work for x versions as well, as long as the md5sum matches

[15:11] <mvo> zyga-ubuntu: +100
[15:12] <elopio> kalikiana: I think so. I built a snapcraft.snap from your branch. Installed it with --dangerous. Ran container builds once, core and snapcraft are installed. Ran it again, only snapcraft is installed.
[15:14] <elopio> so it's identifying the repeated core. But as far as I understand, it should also identify the same snapcraft. Unless I'm missing a step or misunderstanding something...
[15:16] <kalikiana> elopio: Yeah. It's just the .snap files.
[15:21] <kalikiana> elopio: Does the code make sense to you? I don't know if there's a case I'm missing...
[15:24] <elopio> I think it makes sense. From reading the code, I got the idea that both store and local snaps would be checked and installed only if needed. kalikiana is there something you want me to try here?

[16:13] <mvo> slangasek: the other way around :)
[16:13] <slangasek> mvo: once tested, I will change it in livecd-rootfs and you will make no changes to snapd? :)
[16:13] <mvo> slangasek: if the re-exec env does not work for you I can fix in snapd, otherwise I will leave it out of snapd
[16:13] <slangasek> ok
[16:13] <mvo> slangasek: correct
[16:14] <elopio> kalikiana: here's an idea. When snapcraft is x2 in the host, in the container it will be installed as x1 on the first execution. On the second execution it compares x2 with x1, and then reinstalls it on the container. Now both the host and the container have x2, so the third execution will not reinstall it. Would that make sense?
[16:14] <mvo> slangasek: I think it makes more sense to customize the env in casper than to hardcode this behaviour in snapd. if you give me a pointer how I can do it I can test it here myself
[16:16] <slangasek> mvo: the rootfs is an overlay, so everything is editable; I was going to drop a snippet into /etc/systemd/system/snapd.service.d/ that sets Environment=SNAP_REEXEC=0
[16:16] <slangasek> mvo: file extension must end in .conf, and Environment must be set under a [Service] block
[16:19] <mvo> slangasek: ta
[16:19] <mvo> slangasek: testing now
[16:26] <slangasek> mvo: tested here also, and it passed
[16:26] <jdstrand> mvo: this isn't super-urgent since the apparmor accesses for snap-confine for the nvidia thing are safe, but I'm really puzzled how a stat on a file in /dev is causing those for you. I *think* the root cause was that my original PR was always intended for 2.28, but for some reason didn't make it there (so that is something to consider how to improve)
[16:27] <kalikiana> elopio: Ah. Yes. It would be looking for the same x2.snap which wouldn't be there.
[16:27] <mvo> slangasek: reliable?that is great
[16:27] <kalikiana> elopio: Unfortunately the x is a continuous number, nothing we can do here
[16:28] <mvo> jdstrand: I'm not sure either, I think we need to do a proper retrospect on this
[16:28] <mvo> jdstrand: when the fires are out of course :)
[16:28] <zyga-suse> jdstrand: could it be the snappy-dev-app helper?
[16:28] <mvo> jdstrand: so probably post-sprint
[16:29] <jdstrand> mvo: sure, that's fine. there were several issues. I want to make sure they are all knownand addressed
[16:29] <mvo> jdstrand: yeah, I think we are in agreement
[16:29] <mvo> jdstrand: do you think we need more for the .4 release?
[16:29] <jdstrand> mvo: for example, I thought I did the initial PR inenough time for it to be in 2.28 (indeed, I worked on it with priority so it would be there), but I must have missed a fork
[16:30] <mvo> jdstrand: I can check the exact timing
[16:30] <kalikiana> sergiusens: Can this be merged, please? https://github.com/snapcore/snapcraft/pull/1512
[16:30] <mup> PR snapcraft#1512: pluginhandler: clean error for BasePlugin.run{,_output} <Created by kalikiana> <https://github.com/snapcore/snapcraft/pull/1512>
[16:30] <jdstrand> mvo: so, why did I miss that, how can I not miss it in the future, how can snapd team make that easier for me. that sort of thing
[16:31] <zyga-suse> jdstrand: was the PR tagged for 2.28?
[16:31] <zyga-suse> (tagged as in github milestone)
[16:31] <mvo> jdstrand: +1
[16:31] <jdstrand> mvo: obviuosly there is the QA aspect (why didn't QA see that an lxd consuming snap broke, why didn't qa see that opengl failed on nvidia)
[16:31] <jdstrand> (I know that last one, the CI tests don't have nv hardware, which is why I mocked it)
[16:31]  * jdstrand happens to also not have nvidia hardware
[16:31] <zyga-suse> jdstrand: qa process doesn't involve nvidia unfortunately
[16:32]  * jdstrand nods
[16:32] <jdstrand> zyga-suse: right, so we need to figure out how to do that, even if manual, whenever we see changes for nv
[16:32] <jdstrand> eg, hey zyga-suse, I patched something with nvidia, can you test real quick?
[16:32] <zyga-suse> jdstrand: agreed
[16:33] <zyga-suse> jdstrand: we were discussing similar measures
[16:33] <jdstrand> niemeyer also said we should all run candidate.
[16:33] <zyga-suse> jdstrand: all releases smoke tested on nvidia HW
[16:33] <zyga-suse> jdstrand: and also all nvidia-touching code really tested as well
[16:33] <jdstrand> anyway, don't have to discucss here. niemeyer and I talked about it. I'd like to participate in the post-mortem to make sure I know all the agreements and can adhere to them
[16:34] <zyga-suse> +1
[16:34] <jdstrand> zyga-suse: yeah
[16:35] <jdstrand> like, I *knew* nvidia was busted. so I did the PR. unfortunately it didn't hit .28(failing), the fact that I happened to notice nv would fail was a failing. if we actually needed additional apparmor rules, that was also a failing (I'm really curios if they were actually needed)

[16:38] <kalikiana> elopio: Can you please comment on the PR? I'm really trying to get my list of PRs down :-D
[16:39] <elopio> uh, sorry, my comment was caught in a network issue.
[16:40] <kalikiana> elopio: Ah, I see it now... not to be demanding, but I was thinking *review* comment ;-)
[16:40] <mvo> slangasek: for me the journy was slightly more complicated, when I do "printf "[Service]\nEnvironment=NO_REEXEC=0" > /etc/systemd/system/snap.subiquity.started.service.d/no-rexec.conf" (and added the basedir) things work, but it needs to be that because the "snap run" that starts subiquity is indepedent of snapd and will not inherit the environment
[16:40] <elopio> kalikiana: you have it.
[16:40] <mvo> slangasek: *if* this is a sufficient workaround for now I will go ahead with 2.28.4
[16:41] <mvo> slangasek: and leave the re-exec disable to casper. I can help with the PR if you point me to the right branch once .4 is out :)
[16:41] <kalikiana> elopio: Ah, you did it separately. This distinction between "just comment" and proper reviews is really silly... but anyway, thanks a lot!
[16:41] <slangasek> mvo: yes, that looks like a sufficient workaround to me
[16:41] <slangasek> mvo: I'm going to shove it into livecd-rootfs rather than casper
[16:41] <mvo> slangasek: thank you, that sounds good as well, let me know if I can help

[16:43] <kalikiana> also elopio ^^
[16:44] <elopio> kalikiana: I like that distinction. I don't feel good about -1 a PR when I don't understand something. Like in this case.
[16:44] <elopio> one could argue that a -1 is the right thing to do, because this behaviour should have been explained in a PR comment somewhere. But still it's not clear if it's my fault because I'm being dumb, until we dig further.
[16:46] <kalikiana> elopio: Hmm yeah. To me it would be clearer if you could have a ? icon there, and turn it into a +1 or -1 as needed, like the "approve" and "discmiss" buttons you get at the bottom
[16:46] <kalikiana> Really the fact that it splits the work-flow so weirdly is what bugs me

[17:06] <Chipaca> anyway, EOD for me
[17:06] <Chipaca> o/
[17:13] <jdstrand> zyga-suse: you do *not* need apparmor rules for the files to stat them. you need read on the directory the files are in. That is why I am puzzled why the /dev accesses were needed (and why the /sys denials popped up).
[17:13] <jdstrand> I suspect the /sys accesses are just noise and that the /dev accesses are not needed at all
[17:13] <zyga-suse> aha, interesting
[17:13] <zyga-suse> I didn't know that, I agree that some of those are probably not needed in that case
[17:14] <jdstrand> this is why the mocked nvidia devices passed the test
[17:14] <zyga-suse> I was trying to be conservative in hard situation (time running out, remote access to hardware)
[17:14] <jdstrand> spread tests
[17:14] <zyga-suse> I'll gladly research why the sys access showed up
[17:14] <jdstrand> I'm super-curious on that. also curious if they still show up if they are just noise
[17:15] <jdstrand> I suspect they are cause snap-confine isn't going to do anything with any of that. it is just going to stat the files and add them to the cgroup
[17:15]  * zyga-suse was hoping to do some updates on snap-update-ns but today turned out different
[17:16] <zyga-suse> I found a bug where snap-update-ns doesn't do what it should, I need to debug that
[17:16] <zyga-suse> but now I need a break
[17:16] <zyga-suse> o/
[17:16] <jdstrand> I suspect the udev lib calls snap-confine does a little earlier are triggering those, then udev ignores nvidia and moves on. then we stat and are good
[17:16] <jdstrand> zyga-suse: my curiosity is certainly not a reason to deprioritize other things :)
[17:17] <jdstrand> I would like to remove the /dev rules if possible
[17:17] <zyga-suse> no no, it's not your fault, I'm just tired and I want to wrap up that branch before jumping onto other topics
[17:17] <zyga-suse> who knows, maybe in .5 :)
[17:17]  * zyga-suse knocks on wood
[17:18] <jdstrand> cause access to the devices is more than the setuid snap-confine needs (though, it is just read, but still)
[17:18] <zyga-suse> jdstrand: I'm surprised stat is not triggering apparmor checks btw
[17:18] <jdstrand> there is a bug on that
[17:19]  * jdstrand finds
[17:19] <zyga-suse> jdstrand: it's an information leak via (very) expensive enumeration
[17:19] <zyga-suse> aha

[19:57] <jdstrand> zyga-solus: honestly though, there are a number of info leaks-- I'd prefer to see fixing those. all of a sudden mediating stat is ging to be *painful* for policy
[19:57] <zyga-suse> anything small?
[19:59] <jdstrand> I would suggest going to #apparmor on OFTC and asking if there is something bitesize

[08:30] <Laney> hey didrocks
[08:34] <duflu> Hi Laney
[11:25] <luna__> cool did not know you could have many different versions of the same snap installed
[11:25] <jamesh> only if you turn on the experimental feature
[11:26] <jamesh> and there's no guarantee that every snap will function correctly in that mode
[11:28] <luna__> ah alright
[11:28] <luna__> then i know, listening to Igor at LAS 2021 Online
[11:29] <jamesh> e.g. if an app is using GApplication/GtkApplication to implement single instance via ownership of a D-Bus name, it's likely that you won't be able to run both versions simultaneously
[11:30] <luna__> did hear some of it last year however when i was helping voluenteer/host this talk in November 2020
[11:30] <luna__> jamesh: alright thats good to know :)
[11:30] <jamesh> launching the second might just open a window from the first
[11:30] <luna__> Igors example was VLC 3 and VLC 4
[11:30] <luna__> but good to know its not working with everything
[11:32] <jamesh> It does a good job of keeping the resources managed by snapd separate, but there can be other system state outside of snapd's control.
