Device gets bricked after trying to upgrade Core snap

denis · May 1, 2017, 2:54pm

I have a custom armhf board with custom gadget and kernel snap. All that assembled with ubuntu-image.

denisnone@localhost:~$ uname -a
Linux localhost.localdomain 4.10.1-dac_cpu+ #1 SMP Tue Apr 25 11:27:22 CEST 2017 armv7l armv7l armv7l GNU/Linux

This is the initial point before refresh:

denisnone@localhost:~$ snap info core

Running this:

denisnone@localhost:~$ snap refresh core --beta

Then it freezes on this stage:

[|] Setup snap "core" (1805) security profiles (phase 2)

The slash keeps spinning until finally scheduled reboot comes.

It reboots well but:

denisnone@localhost:~$ snap change 38

Then I issue a second reboot after refresh. But it finishes in initramfs.

Trying to hack it:

(initramfs) reboot

And yes it boots, but complains about it:

So basically what it does is harakiri. It can’t cure itself without intervention.

And interesting fact: I couldn’t get core snap refreshed not even once. And not only force refresh leads to death, but also when a new version of core comes out in a particular tracking channel. (No surprise) What can cause the problem? Kernel? Gadget? ubuntu-image?

I have a raspi3 and it switches cores and channels smoothly on it’s official image. It still hangs on “Setup snap “core” () security profiles (phase 2)”. But after reboot it’s on a new core snap.

The kernel is a zesty kernel from official Ubuntu repository from master branch. It couldn’t get xenial kernel working on my board, besides I need some improvements incorporated in linux 4.6-4.8, so 4.4 is not an option for me.

Hey

Can you please share any relevant journal/syslog messages? Before trying to refresh the core snap, did you try to refresh / install anything else (e.g. even hello-world) if so, did that succeed?

Can you tell me more about this. Is this using stock PI3 kernel/gadget image? If so I’ll try to reproduce this.

zyga-snapd · May 1, 2017, 3:51pm

Ah, I missed this. Those expanders are unfamiliar to me. So, this is very interesting. Can you please harvest system log messages that are related to this this time?

mvo · May 1, 2017, 4:27pm

Thanks for this report and sorry for the trouble you experience. Could you please paste the output of:

$ fw_printenv |grep snap

I.e. the boot configuration of uboot would be great.

There are at least two bugs here:

fails to connect the interfaces (core-support)
fails to rollback from the broken core

The uboot environment hopefully helps with figuring out why (2). The syslog data that @zyga-snapd asked for should help with (1).

Thanks!

Judging from the first sentence of the original post, I’d say no .

Hello,

On raspberry-pi3 this works silently in the background when a new core version comes out.
But when forced to refresh from a terminal via ssh this gives that:

So it refreshes well, but it sits in that “security profiles (phase 2)” forever until scheduled reboot hits.
And yes, the image is an Ubuntu official image.

About my board.
Installing/removing snaps works without problems, “hello-world” for example installs well.

Docker snap installs but gives an INFO:

2017-05-01T16:32:11Z INFO cannot auto connect docker:docker-cli to docker:docker-daemon: (slot auto-connection), existing connection state "docker:docker-cli docker:docker-daemon" in the way
docker 1.13.1-0 from 'docker-inca' installed

I will collect journald information and post it shortly after re-flashing my image on sd-card to clean all the mess and start over again.

I have two boards: my custom board with my custom image and a reference one - raspi3 with official image.

ogra · May 1, 2017, 5:13pm

dropping into the initramfs prompt indicates either an issue with your kernel snap (wrong or broken initrd) or (more likely since it originally booted) an issue with the updating of the bootloader variables in uboot after core upgrade.

do you get a proper listing of gadget, kernel and core snap after a fresh flash of your custom image when using “snap list” right after first login (i.e. was your image initialized properly on first boot) ?
can you show us your uboot environment … (as @mvo said above, the output of fw_printenv is essential here)
does your uboot have the proper patches and did you create a 131072 bytes big redundant uboot.env file when creating the gadget (see README.md of the pi3 gadget on how to create it) ?

Hello, @ogra, @mvo.

After first boot this looks like that:

denisnone@localhost:~$ snap list
Name            Version  Rev   Developer  Notes
alsa-utils      1.1.2-5  69    canonical  -
avahi           0.6.32   36    ondra      -
core            16-2     1580  canonical  -
dac-cpu         16.04-1  x1               -
dac-cpu-kernel  4.7.0    x1               -
htop            2.0.2    71    maxiberta  -

Gadget and kernel snap are listed well.
Initialize device seems to fail:

@denis Thanks for all those details. I’ve changed these posts slightly to use pre-formatted boxes so that the content looks more readable in the forum. In the future, when you have so much volume of data it’s best to use a paste service (gist, for example) and link here so that the conversation itself isn’t compromises by the volume of information provided.

denis · May 1, 2017, 7:37pm

Thanks @niemeyer. I tried to use “hide detail” macro, it shows well in preview but then when posted it doesn’t work. Next time I’ll try boxes and paste services.

ogra · May 2, 2017, 11:38am

i have filed https://bugs.launchpad.net/snapd/+bug/1687608 for the pi3 issue you mentioned above (since we are discussing two different things in this thread, lets focus on your bricking issue here and treat the pi3 bug as a bug)

ogra · May 2, 2017, 12:46pm

going back to your initial post, here is my theory what happens:

you refresh core … it puts the new snap in place, sets “snap_mode=try” and “snap_try_core=core_1805.snap” …

it reboots into the new setup, finds core_1805 unsuitable for whatever reason (to be determined) and removes the snap from disk, but here snapd fails to unset “snap_mode” and “snap_try_core” (also to be determined)

you do the manual reboot with these vars still set, the system does not find the snap file despite “snap_core” on the kernel cmdline pointing to it which makes you end up in the initrd.

your uboot vars in the second post seem to show the same behaviour, i assume you did not do a manual reboot there yet ?

zyga-snapd · May 2, 2017, 1:05pm

Can you please say what does snap version say?

denis · May 2, 2017, 1:35pm

What I’ve found so far:
uboot is configured to save environment variables not on mmc/fat but to mmc at offset 512 just after MBR.
When I initially worked on that, I found that I can’t let it save to FAT because I have a version 2013, which ruins FAT partition when it writes to that. So I decided to let it save after MBR and restore variables from there, but then after boot delay, a boot script re-reads environment variables from file from FAT partition modifying old vars with those prepared by snapd. This is how new core_1805 is passed to kernel and I thought it would be a workaround.
But what happens then is that uboot sets “trying” variable but saves it as raw after MBR. If snapd senses for that “trying” on next boot and obviously it’s not in the file at FAT partition. And everything depends on what snapd does in that case.

I had plans on upgrading my uboot to version 2017, but I wanted to postpone it as far as I can. It’ll take some time as it involves also to prepare a SPL preloader as well. And SPL depends on some headers that are generated automatically based on SoC configuration which in turn depend on FPGA project. It may be a one-day deal or it can take one week, never know.

I will work on that in parallel with some other tasks. I’ll try first old 2013 SPL with new 2017 UBoot.

But still is it the cause of the problem? And not something else? Does snapd refuse to apply new Core because of “trying” or there is also something else in addition?

ogra · May 2, 2017, 2:00pm

snapd as well as ubuntu-image will only use the uboot.env file (for ubuntu-image this requires the uboot.conf link to point to it) … we picked this setup to avoid exactly the fat corruption with older uboot. due to the fact that the uboot.env is a pre-created binary blob file with a fixed size, it will never actually change on the fat.

changes are just atomic, bit wise modifications inside the fixed size file.

it should work just fine with your uboot whatever version it is. essential is that you set the right config options at build time like CONFIG_ENV_SIZE, CONFIG_ENV_IS_IN_FAT and CONFIG_SYS_REDUNDAND_ENVIRONMENT that you can see in our uboot.patch

denis · May 3, 2017, 11:23am

Thanks, @ogra, this works now. I used my U-Boot 2013.01.01 (May 02 2017 - 19:59:58) with your recommended CONFIGs from patch and rpi.h. Uboot reads envs, saves envs, snapd does the same. And finally Core snap gets really refreshed without problems. I can change channels now as on raspi3 now. (but snapd holds ssh session as usual, no surprise here ) The only thing bothers me is unaligned access when U-Boot reads envs on start. This looks like this:

reading uboot.env
FAT: Misaligned buffer address (3fed7738)
In:    serial
Out:   serial
Err:   serial

It doesn’t influence boot process but looks ugly. I will need to dig in there.

The versions are 2.24 and 2.25. All those Canonical supplied in stable-candidate-beta-edge channels this week

ogra · May 3, 2017, 1:14pm

take alook at Bug #1687608 “running “snap refresh core” on an UbuntuCore devic...” : Bugs : snapd you can actually ctrl-c the UI (if you hit it a few times) to get your console back (note that you only stop the UI with this, snapd will move on operating)
