Rob Shearman 25bf0a409a rpcrt4: Update TODO list.
Out-of-memory check is performed by NdrAllocate and so isn't required to 
be done in the unmarshalling functions.

Rob Shearman 4a028589eb rpcrt4: Document NdrAllocate. 2007-12-14 12:24:24 +01:00
Rob Shearman c7261b732b rpcrt4: Partially revert commit 18faf3184b2ea263d77c2a7ad92eef27bc4ba08f.
Tests show that NdrPointerFree (and hence NdrFree) don't check whether 
the memory was allocated with NdrAllocate before freeing it. This makes 
sense as servers don't need to use NdrAllocate to allocate memory being 
returned and so this commit caused that memory to be leaked.

NdrAllocate hasn't been changed as the tests show it is correct and it 
appears that the memory list is used to implement the RpcSs memory model.

Rob Shearman ce220e2b5f rpcrt4: Free the base pointer in PointerFree when freeing a pointer with RPC_FC_P_DEREF. 2007-12-14 12:24:03 +01:00
Rob Shearman d5ff3467bc rpcrt4: Fix the check in NdrPointerFree.
Add comments to justify why this is the only check that is needed.

Rob Shearman ded4b86625 Revert "rpcrt4: Try to free every non-stack pointer in PointerFree now that NdrFree does the sanity checking for us.".
This reverts commit 6db648302ce43f625a073426a35a6f40b7869d8b.

Tests show the assumptions in a commit that this commit depends on are 
not valid.

Rob Shearman 17132f7e1f rpcrt4: Set fMustAlloc to TRUE when unmarshalling an object pointer. 2007-12-05 13:48:59 +01:00
Rob Shearman 2a9fae7565 rpcrt4: Set the destination pointer in PointerUnmarshall before calling the referenced type's unmarshalling routine.
When a pointer that is dereferenced is encountered then this can result 
in a stale pointer (i.e. the one that is marshalled into the buffer for 
the embedded pointer unmarshalling case) being used instead of the one 
that was intended.

Rob Shearman d8e467b0fd rpcrt4: Reverse the conditions for which *pPointer is assigned base_ptr_val in PointerUnmarshall.
In one condition (fMustAlloc == TRUE), base_ptr_val may be uninitialised
and so cause a valgrind warning. Reversing the check is harmless and
doesn't result in a performance decrease.

Rob Shearman 4e8f69ac2d rpcrt4: Move forcing of fMustAlloc to NULL to the callers of EmbeddedPointerUnmarshall.

Dan Hipschman 8caa325eb7 rpcrt4: Initialize allocated pointers to NULL in PointerUnmarshall.
This patch initializes allocated pointers in PointerUnmarshall since later
code checks the value for NULL (specifically, NdrConformantArrayUnmarshall).
