[libvirt] [PATCH] esx: Fix potential memory leak in esxVI_BuildFullTraversalSpecItem
If esxVI_String_DeepCopyValue or esxVI_SelectionSpec_AppendToList fail then selectionSpec would leak. Add a free call in the failure path to fix the leak. --- src/esx/esx_vi.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/esx/esx_vi.c b/src/esx/esx_vi.c index aa46532..63ddaa4 100644 --- a/src/esx/esx_vi.c +++ b/src/esx/esx_vi.c @@ -1163,8 +1163,6 @@ esxVI_BuildFullTraversalSpecItem(esxVI_SelectionSpec **fullTraversalSpecList, currentSelectSetName = selectSetNames; while (currentSelectSetName != NULL && *currentSelectSetName != '\0') { - selectionSpec = NULL; - if (esxVI_SelectionSpec_Alloc(&selectionSpec) < 0 || esxVI_String_DeepCopyValue(&selectionSpec->name, currentSelectSetName) < 0 || @@ -1173,6 +1171,7 @@ esxVI_BuildFullTraversalSpecItem(esxVI_SelectionSpec **fullTraversalSpecList, goto failure; } + selectionSpec = NULL; currentSelectSetName += strlen(currentSelectSetName) + 1; } } @@ -1186,6 +1185,7 @@ esxVI_BuildFullTraversalSpecItem(esxVI_SelectionSpec **fullTraversalSpecList, failure: esxVI_TraversalSpec_Free(&traversalSpec); + esxVI_SelectionSpec_Free(&selectionSpec); return -1; } -- 1.6.3.3
