action #91947

Updated by szarate 5 months ago

We had regression in cifs-utils: https://bugzilla.suse.com/show_bug.cgi?id=1184815 - mounting was broken when used with krb
This scenario could be made into automated test to prevent from happening again

## Acceptance Criteria

AC1: network/cifs.pm is testing mounting with krb as indicated in the bug, and the test is run across all maintenance releases

## Suggestions

* Check what´s needed for the krb5 server to be configured, so that the following mount, either passes or fails (try first with a lower version of the package or SP?)

> # Enable CIFS debug to get more info from dmesg
> echo 'module cifs +p' > /sys/kernel/debug/dynamic_debug/control
> echo 'file fs/cifs/* +p' > /sys/kernel/debug/dynamic_debug/control
> echo 7 > /proc/fs/cifs/cifsFYI
>
> # Command to mount CIFS FS ( error 126 )
> # mount -t cifs //dfs.moon.corner.tech/software/SAP /opt/software/share -o gid=sapsys,file_mode=0440,dir_mode=0775,sec=krb5,username=NG-CB-UBD201$,vers=3.0
> mount error(126): Required key not available
> Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

* **AC1**: Provide two verification runs for 15-SP2, one with the version that passes and another with the version that fails.
* **AC2**: branch the changes to run unconditionally on 15-SP3
* **AC3**: Soft fail for openSUSE
