Subject: [PATCH 33/83] DDF: Fix NULL pointer dereference in
|
|
validate_geometry_ddf()
|
|
|
|
A relatively recent patch added a call to validate_geometry() in
|
|
Manage_add() that has level=LEVEL_CONTAINER and chunk=NULL.
|
|
|
|
This causes some ddf tests to segfault which aborts the test suite.
|
|
|
|
To fix this, avoid dereferencing chunk when the level is
|
|
LEVEL_CONTAINER or LEVEL_NONE.
|
|
|
|
Fixes: 1f5d54a06df0 ("Manage: Call validate_geometry when adding drive to external container")
