Subject: [PATCH] qemu: hotplug: Don't access srcPriv when it's not allocated
|
|
|
|
The private data of a virStorageSource which is backing an iSCSI hostdev
|
|
may be NULL if no authentication is present. The code handling the
|
|
hotplug would attempt to extract the authentication info stored in
|
|
'secinfo' without checking if it is allocated which resulted in a crash.
|
|
|
|
Here we opt the easy way to check if srcPriv is not NULL so that we
|
|
don't duplicate all the logic which selects whether the disk source has
|
|
a secret.
