Hi All,
I've made some progress since this morning:
- I support either XorMagic or Compressed rgbIn
- The blob is dumped properly with mapi_request
I can't actually use the compression() keyword in pidl and have instead
been:
- adding the [public,nopull] keywords to the mapi2k7_request
structure + wrote a custom implementation
- cloning the existing ndr_pull_compression_xpress_start/
ndr_pull_compression_xpress_chunk and modified them to match the
expected behavior.
Preliminary pointers while this cloning is required at the moment:
- the decomp routine is using some extra parameters we do not
have in the compressed MAPI blob.
- there is a header problem when using compression (it looks for
ndr/compression.h header file, which isn't installed)
The following is a list of what remains:
- "chained calls" behavior/code needs to be implemented
- The current behavior is only implemented for request and need
to be extended to response
- I am currently working on adding the implementation for the
AUX_HEADER structure we have in rgbAuxIn and rgbAuxOut buffer
- We need either to extract the original obfuscate_data call
from ndr_{pull,push}_mapi_request code to an upper layer or
factorize the code with a custom parameter.
I have attached 2 sample ndrdump output for EcDoRpcExt2:
- one demonstrating the dump of a compressed request
- the other showing the dump of a xormagic request
Cheers,
Julien
