[yocto] wic create - bad ownership of directories inside image

Tue Aug 27 01:08:07 PDT 2019

Hi Randy,

FYI
I created a completely new poky clone.
Then I set up a config for "genericx86" and built a core-image-minimal

Here are the results

1)    Using "thud" branch -> problem persisted

2)    Using "warrior" branch  --> problem solved

Regards
Jochen

Hi Randy,

removing my core-image-minimal.bbappend does not change anything.
I still get the same behavior.

Here are my version
poky 2.6.1

$ bitbake -version
-> 1.40.0

The next step would be to upgrade my poky to the latest version.
Right now I can't do that, but I'll give it a try in the next few weeks.

Many thanks for your assistance.

Regards
Jochen

Hello Randy,

thanks for your reponse and sorry for my late reaction.

In order to test, if the problem can be reproduced reliably, I performed a clean rebuild as follows

$ source oe-init-build-env build-tca5-32
$ rm -rf tmp
$ rm -rf sstate-cache
$ bitbake core-image-minimal
$ wic create mkefidisk -e core-image-minmal

I then mounted the resulting image file "mkefidisk-201908221701-sda.direct" using a loopback device (losetup)
Inside the Image all directories have UID/GID 1000/1000, which corresponds to my host user.
Files however have UID/GID 0/0.

Hi Jochen,

I'm not able to reproduce the error, see below (1).

What version of oe-core/bitbake are you using?

I'm using the latest master branches:

oe-core: 64f9fd2a1e quilt: added less to RDEPENDS list
bitbake:  28b3f0d8  runqueue: Optimise build_taskdepdata slightly

So the answer to your question is "yes I can reproduce the behavior".

One sidenote
- I am using an appended core-image-minimal not the default

What is the bbappend? Is it publicly clonable? What happens if you drop that addition?

I followed your steps above and mounted my image as follows:

Hi Jochen,

No and I've never seen this particular extreme symptom.

There is a known, generally rare bug:
    Bug 12434 - pseudo: Incorrect UID/GID in packaged files
    https://bugzilla.yoctoproject.org/show_bug.cgi?id=12434
but that usually shows up when building.

You could check you build logs for the generic stings from:

    glibc-locale-2.26: glibc-locale:
    /glibc-binary-localedata-en-gb/usr/lib/locale/en_GB/LC_MEASUREMENT
    is owned by uid 3004, which is the same as the user running bitbake.
    This may be due to host contamination [host-user-contaminated]

Is your issue 100% reproducible?
