Subject: [PATCH 2/4] iSCSI: Store auth info in NodeInfo tuples
|
|
|
|
This seems to have been overlooked in 9280eff7 . When we were
|
|
using libiscsi, the `node` objects were `PyIscsiNode` instances
|
|
(I think), with `getAuth` and `setAuth` methods that let you
|
|
read and set the authentication information for the node. We
|
|
used `getAuth` in `iScsiDiskDevice.dracut_setup_args()` to
|
|
include the auth information in the `netroot` arg. anaconda
|
|
also expects the `node` attribute of an `iScsiDiskDevice`
|
|
instance to be a `PyIscsiNode` and calls its `getAuth` method
|
|
to populate the kickstart data for the node.
|
|
|
|
When we ditched libiscsi and turned the `node` objects into
|
|
`NodeInfo` namedtuples, this was missed and not handled at all.
|
|
Both blivet and anaconda are still trying to call methods that
|
|
these node objects just don't have any more. The blivet call
|
|
was changed from `getAuth()` to `get_auth()` in 4e8f941b , but
|
|
apparently whoever did that didn't notice that neither method
|
|
exists at all for these objects any more...
|
|
|
|
Here's my attempt to fix this: basically, just stuff the auth
|
|
information into the `NodeInfo` instances when we log in. I
|
|
thought of several different ways to do this, but I think in
|
|
the end it always has to boil down to storing the auth details
|
|
on the node object when we log in, so let's just go with the
|
|
obvious way. We could mimic the `getAuth` and `setAuth` methods
|
|
pretty easily for 'compatibility', but it doesn't seem worth
|
|
it, we'd probably still be missing other bits of the interface.
