Snapd on yocto 3.1 (dunfell)

snapd
1

Hi there,

so I’ve been trying to get

working on the current Yocto Dunfell release on this fork

https://github.com/crossbario/meta-snappy/commits/support-dunfell

Using the (now available) libseccomp recipe in Yocto, I am getting to:

Note that this is still using snapd 2.38 rather than the current 2.47.1.

I am wondering what the best approach for porting the patches to the current snapd code base would be … and if there is interest in possibly merging this upstream.

Any hints or comments welcome!

Cheers,
/Tobias

The current recipe is for 2.38, which is a bit old and probably needs a version bump. Hopefully there shouldn’t be too many changes needed. Feel free to update the recipe and open a PR to morphis/meta-snappy. I can review the changes and help you land it.

Which patches do you have in mind?

Which patches do you have in mind?

these https://github.com/morphis/meta-snappy/tree/master/recipes-support/snapd/files

eg applying to v2.47 fails with


ERROR: snapd-2.47.1-r0 do_configure: QA Issue: snapd: configure was passed unrecognised options: --enable-seccomp [unknown-configure-option]
ERROR: snapd-2.47.1-r0 do_configure: Fatal QA errors found, failing task.
ERROR: Logfile of failure stored in: /home/oberstet/.yocto/simplethings-hub-rpi3-dunfell/build/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/snapd/2.47.1-r0/temp/log.do_configure.103818
ERROR: Task (/home/oberstet/.yocto/simplethings-hub-rpi3-dunfell/src/meta-snappy/recipes-support/snapd/snapd_2.47.1.bb:do_configure) failed with exit code '1'

how is that best done practically? manually editing the patch files? recreating new patches on top of the current code by manually transporting each change?

ok, had a quick look at one example. I think I’ll need to recreate the patch files newly … too much changed in the meantime …

IIRC using devtool became a recommended way to work on recipes including patching the source code.

Having a quick look at the patches, I think you can drop:

I think that 0001-packaging-use-templates-for-relevant-systemd-units.patch and 0005-cmd-add-poky-to-the-list-of-distros-which-don-t-supp.patch could be fixed upstream and then cherry-picked as needed.

As for the last patch, the projects I worked on usually defined their own distro instead of using Poky, but it should be fine if one stays with the out of the box Yocto experience.

thanks for the hints! that should allow me to work on this.

rgd patch 5: seems like the default distro name “poky” is known to upstream at least in some places:

just from pattern matching, sth like

if !release.DistroLike("debian", "ubuntu", "poky") {

etc seems to make sense … I’ll have a closer look

rgd devtool, found this https://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#dev-manually-upgrading-a-recipe

alright, got the current snapd version now, but I get a sigsegv =(

I was able to update the recipe to snapd 2.41.1 and it seems to work in qemu, however the raspberry pi image that we produce is still faced by similar issues.

Here is a log that I just gathered. Do note that the last two start attempts failed with different errors.

Do these logs hint to anything fundamentally wrong that we are doing ? (cc @zyga-snapd)

Interestingly all 3 panics (one in the log @oberstet provided) point to a regex from different code paths. That would suggest there might be something off the the stdlib or the build.

Could you try to build a minimal Go code sample using regexp and run it on rspi? This should be sufficient:

package main
import (
	"fmt"
	"regexp"
)
func main() {
	var r = regexp.MustCompile("foo(bar)?[123]+")
	fmt.Println(r.MatchString("foo111"))
	fmt.Println(r.MatchString("foobar333"))
	fmt.Println(r.MatchString("foobarbar333"))
}

You can use devtool to create a new recipe in your $WORKSPACE.

So it seems the issue was already fixed for x86 but needed a similar treatment for armhf/aarch64. I was able to get snapd working by adding

GO_DYNLINK_arm = ""
GO_DYNLINK_aarch64 = ""

here https://github.com/morphis/meta-snappy/blob/1779e0054089d92002cc09289529e6b95311530b/recipes-support/snapd/snapd_2.38.bb#L59

Thanks for opening you PR with support for dunfell. I’ve finally taken time to build everything and land it.

I’ve opened a followup with some cleanups: https://github.com/morphis/meta-snappy/pull/30 Since we’re not using Yocto much internally, I’d be great if someone else than me gave it a go too. If you have some time, please take a look and try to build it locally.

Once it lands, I’ll open another one with an update to 2.48 (or 2.49 if that is released earlier).
