Subject: [PATCH] loader: add check for unknown file type
|
|
|
6497cf |
|
|
|
6497cf |
So we can provide a meaningful error message in case the provided path
|
|
|
6497cf |
is not accessible to running process.
|
|
|
6497cf |
|
|
|
6497cf |
e.g: running HOME=/root osinfo-query os we would get
|
|
|
6497cf |
`Error loading OS data: Unexpected file type`
|
|
|
6497cf |
and now we get
|
|
|
6497cf |
`Error loading OS data: Can't read path /root/.config/osinfo`
|
|
|
6497cf |
|
|
|
6497cf |
This error was first hit with v2v [0] that was leaking $USER and $HOME
|
|
|
6497cf |
of root user when osinfo-query as vsdm user with `sudo -c vdsm`. The
|
|
|
6497cf |
example above is a simple way to show lack of permision of
|
|
|
6497cf |
osinfo-query to read the root's $HOME.
