[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] libxenlight: fix memory leaks
Hi all,
this patch fixes many memory leaks currently present in libxenlight.
In particular:
- all the temporary flexarrays allocated in the create
device functions must be freed;
- all the strings that don't need to be modified can be added as they are
to these temporary flexarrays instead of duplicating them;
- any data returned to the user shouldn't be added to the global
memory tracker so that the user can free it whenever he wishes.
