Subject: [PATCH] Fix UBI 9 scan
|
|
|
909fca |
|
|
|
909fca |
In offline mode when scanning a cointainer based on UBI 9 the
|
|
|
909fca |
system_info probe failed because the function `_offline_get_hname` which
|
|
|
909fca |
reads from `/etc/hostname` returns an empty string which causes
|
|
|
909fca |
`__sysinfo_saneval(hname)` check to return zero which in turn causes the
|
|
|
909fca |
probe returns an error. We can prevent this situation by replacing the
|
|
|
909fca |
empty string by `"Unknown"`, which we already do when the `hname` is
|
|
|
909fca |
`NULL`.
