The torture test DCOM-SIMPLE now successfully does an
IStream_Read and a IStream_Write call.
This test can now be run successfully against the "Simple DCOM" Visual
Studio example.
(You have to quote out line 337 in pidl. pidl complains if the variable
that contains the array size follows the array. I still need to fix this
properly)
Next goals:
- Clean up code
- Server side support
- Support custom marshalling
- Support DCOM interfaces in files other then dcom.idl
the [gensize] property to a struct or union will make pidl generate a
ndr_size_*() function.
(not all nasty bits of NDR are completely covered yet by the
ndr_size*() functions, support for those will be added when necessary)
I also have a local patch (not applied now) that simplifies the pidl output
and eliminates the number of functions required. It would, however, make
pidl more complex.
for this struct and all sub-structures to be like spoolss relative
pointers (where offset is relative to current position).
volker will test this for me :)
bytes to make sure they are zero. Non-zero values usually indicate one
of two things:
- the server is leaking data through sending uninitialised memory
- we have mistaken a real field in the IDL for padding
to differentiate between the two you really need to run with
"print,padcheck" and look carefully at whether the non-zero pad bytes
are random or appear to be deliberate.
in pidl. This mechanism should be much easier to extend to the
"retrospective subcontexts" that jelmer needs.
also produced more standards complient full-pointer offsets. This
keeps ethereal happy with decoding our epmapper frames.
which the offset applies to. In an array of structures containing
relative members, the offset applies to the start of the array element
being marshalled. Previously, there was no way to access the relevant
structure start as by the time we have hit buffers, the head of the
offset list will be the last structure being marshalled.
Interestingly enough, this makes relstrs go away. I think we thought
they were a special case in samba 3 but it turns out they are just
regular relative elements in the idl. This makes spoolss a lot simpler
than I thought it would be.
I've run the samr and lsa tests and this doesn't seem to break anything.
It looks like security descriptors are the only structures that contain
relative members.
Oh yeah, this will probably require a 'make clean && make' otherwise you
will get bizzare errors.

* neater handling on value() options in IDL. The auto-print code
will now display the right value so you don't need to initialise
it in your C code
I have recoded the core dcerpc packet structures (all the PDUs etc) in
terms of IDL, which means we now use pidl to generate all the code for
handling the most basic dcerpc packets. This is not normally possible
as it isn't completely valid NDR, but pidl has a number of extensions
that make it quite easy.
This also means we get the server side dcerpc
marshalling/unmarshalling code for free.
* added a NDR validator. The way it works is that when the
DCERPC_DEBUG_VALIDATE_* flags are set the dcerpc system will
perform NDR buffer validation. On sending a request the packet is
first marshalled, then unmarahslled, then marshalled again, and it is
confirmed that the two marshalling results are idential. This
ensures that our pull and push routines are absolutely in sync, so
that we can be very confident that if a routine works in the client
then the corresponding routine must work on the server side. A
similar validation is performed on all replies.
* a result of this change is that pidl is fussier about the [ref]
tag. You can only use it on pointers (which is the only place it
makes sense)
* fixed a basic alignment bug in the push side of the NDR code
* added server side pull/push support. Our dcerpc system is now fully
ready to be used on the server side.
* fixed the relative offset pointer list. It must be traversed in
reverse order on push
* added automatic value setting for the size parameter in outgoing
SdBuf structures.
* expanded the ndr debugging code to always give a message on any
failure
* fixed the subcontext push code
* fixed some memory leaks in smbtorture RPC tests
interface. We now support an arbitrary set of flags to each parser,
and these can be used to control the string types. I have provided
some common IDL string types in librpc/idl/idl_types.h which needs to
be included in every IDL file.
* added IDL for the endpoint mapper. Added a test suite that enumerates
all endpoints on the server.
alignment correctly for unions that have non-uint16 discriminants
fixed the union handling in srvsvc.idl. (metze, please take a look at
the changes, your IDL did match what was one the wire in most cases,
but isn't the way IDL is usually coded)
I think this is our first complete pipe for Samba4 (albeit a simple
one). Of course, there may be lots more info levels that Samba3 didn't
do. Time to explore :)
