Subject: [PATCH] Fix segmentation fault problem.
|
|
|
|
When execute iscsi_task_mgmt_lun_reset_async function,
|
|
pdus are already removed from waitpdu list. In iscsi_service
|
|
function, this will call iscsi_process_pdu and release
|
|
pdu from waitpdu again, which cause segmentation fault.
|
|
|
|
Whether waitpud list is NULL should be checked here to avoid
|
|
the problem.
