Description

Improved list reference addition realized during the AddNodes service.

Code version identification

f8d81d7b

Current behavior

AddNodes

The SOPC_NodeMgtHelperInternal_AddRefToNode function performs the following operations:

1. Allocates a new list of references (+1).
2. Copies of existing references.
3. Add the new reference to the new list.

DeleteNodes

The SOPC_NodeMgtHelperInternal_RemoveLastRefInTargetNode function, clear only the memory (not released) The SOPC_NodeMgtHelperInternal_RemoveRefAtIndex function, allocates a fresh new list if references and copies all references except the one to be removed. Clear + Free the memory of the removed reference.

Expected behavior

AddNodes

• Increases the reference list size with a realloc, in order to replace 1. Allocates and 2. Copies.

DeleteNodes

• Decreases the reference list size with a realloc (reference clear before deletion).

Security impact

None

Implementation

Use SOPC_Realloc.
