Description Michael Nosthoff 2018-03-28 13:11:32 UTC 
Hi,

I just updated my buildroot build from 2017.11 to 2018.02. 
It broke my root ssh login.

I see the following message in my journal: 

  dropbear[383]: User 'root' has invalid shell, rejected

In 2017.11 there was no /etc/shells. Now there is one.
My /etc/shells contains only /bin/bash. But not /bin/sh. But my root users has /bin/sh as shell, so the error makes sense.

Some quick comparison shows that the file /etc/shells was added in this commit:

4d279697afbf8fb2952 package/bash: add /bin/bash to /etc/shells

I see on the mailing list Romain Naour posted a series of commits which would also add /bin/sh to shells in the skeleton-init-common. But this is still not applied.

So I would suggest to either apply the patch series for the next maintenance release or remove the before mentioned commit.


Regards,
Michael

Still present in 2018.02.1...

For 2018.02.x, I think it should be fixed by reverting the commit:
http://patchwork.ozlabs.org/patch/899178/

For master, the series should be applied:
http://patchwork.ozlabs.org/project/buildroot/list/?series=24357

In the 2018.02.x branch, we reverted the patch pointed by Arnout. For the master branch, and upcoming 2018.05, we also applied the series pointed by Arnout. Hence this bug is fixed. Thanks!
