Subject: [PATCH] Fix a memory leak in dns_dlzcreate()
|
||
|
|
|
||
|
|
dns_dlzcreate() fails to free the memory allocated for dlzname
|
||
|
|
when an error occurs.
|
||
|
|
|
||
|
|
Free dlzname's memory (acquired earlier with isc_mem_strdup())
|
||
|
|
by calling isc_mem_free() before returning an error code.
|
||
|
|
|
||
|
|
(cherry picked from commit 4a6c66288ff831a3450e6472605d3ef8d668eac7)
|
||
|
|
Conflict: NA
