Subject: [PATCH v4 0/6] SIM Access Profile v4

Hi Johan,

See next version of sap patchset.
I fixed a text license for both already upstreamed patches and those not yet pushed.

/Waldek


Waldemar Rymarkiewicz (6):
Adjust sap/server.c license text to the rest of the code
Sim Access Profile Server
Sim Access Profile connect/disconnect procedures
Add support for SAP protocol
Sim Access Profile dummy driver
Sim Access Profile test scripts

Thanks. I will rearrange if-statements now. I agree, however, defines are to long and will change it in a separate patch not to introduce a mess. The defines are used in already upstream code.
Will send v5 in a while.

Use shorter define names (since they really are quite long), move the
checks into separate functions, e.g. validate_set_transport_protocol_req(),
or redo the if-statement to something like:

if (msg->nparam != 0x01)
return -EBADMSG;
if (msg->param->id != SAP_PARAM_ID_TRANSPORT_PROTOCOL)
return -EBADMSG;
if (ntohs(msg->param->len) != SAP_PARAM_ID_TRANSPORT_PROTOCOL_LEN)
return -EBADMSG;
...
return 0;

It becomes much easier for a human to parse it that way since you get to
process the individual conditions clearly one at a time.

Take your pick ;)

Sure,

Yes, I guess you refer to eg.

case SAP_SET_TRANSPORT_PROTOCOL_REQ:
if (msg->nparam == 0x01 &&
msg->param->id == SAP_PARAM_ID_TRANSPORT_PROTOCOL &&
ntohs(msg->param->len) == SAP_PARAM_ID_TRANSPORT_PROTOCOL_LEN &&
(*msg->param->val == SAP_TRANSPORT_PROTOCOL_T0 ||
*msg->param->val == SAP_TRANSPORT_PROTOCOL_T1))
return 0;

Well, I didn't know how to spit up something like "ntohs(msg->param->len) == SAP_PARAM_ID_TRANSPORT_PROTOCOL_LEN &&" correctly.
Any sugestion?

I've pushed the first two patches in this set, but it's gonna take quite
a bit longer to properly review the rest (at a quick glance I noticed at
least some coding style stuff with over 80-character lines). So the rest
will have to wait until after the next BlueZ release (which will
hopefully happen still today).

Subject: [PATCH v4 6/6] Sim Access Profile test scripts

Add simple SAP client python implementation and a test script.

To run test-sap.py you need Python 2.6 or newer (tested with 2.6 only)
and PyBluez package installed.

Subject: [PATCH v4 2/6] Sim Access Profile Server

Add a Sim Access Server to the SAP plugin and a framework for the dummy
sap driver as well.

* add the server register and unregister rutines
* add server listening socket setup
* add SAP DBus API
* add prototypes for SAP protocol implementation
* add skeleton of dummy SIM driver
