4.3 The _cmsg Structure
4.3 SKBs

CAPI messages are passed between Kernel CAPI and the driver via send_message()
and capi_ctr_handle_message(), stored in the data portion of a socket buffer
(skb).  Each skb contains a single CAPI message coded according to the CAPI 2.0
standard.

For the data transfer messages, DATA_B3_REQ and DATA_B3_IND, the actual
payload data immediately follows the CAPI message itself within the same skb.
The Data and Data64 parameters are not used for processing. The Data64
parameter may be omitted by setting the length field of the CAPI message to 22
instead of 30.


4.4 The _cmsg Structure

(declared in <linux/isdn/capiutil.h>)

The _cmsg structure stores the contents of a CAPI 2.0 message in an easily
accessible form. It contains members for all possible CAPI 2.0 parameters, of
which only those appearing in the message type currently being processed are
actually used. Unused members should be set to zero.
accessible form. It contains members for all possible CAPI 2.0 parameters,
including subparameters of the Additional Info and B Protocol structured
parameters, with the following exceptions:

* second Calling party number (CONNECT_IND)

* Data64 (DATA_B3_REQ and DATA_B3_IND)

* Sending complete (subparameter of Additional Info, CONNECT_REQ and INFO_REQ)

* Global Configuration (subparameter of B Protocol, CONNECT_REQ, CONNECT_RESP
  and SELECT_B_PROTOCOL_REQ)

Only those parameters appearing in the message type currently being processed
are actually used. Unused members should be set to zero.

Members are named after the CAPI 2.0 standard names of the parameters they
represent. See <linux/isdn/capiutil.h> for the exact spelling. Member data

7. Debugging

The module kernelcapi has a module parameter showcapimsgs controlling some
debugging output produced by the module. It can only be set when the module is
loaded, via a parameter "showcapimsgs=<n>" to the modprobe command, either on
the command line or in the configuration file.

If the lowest bit of showcapimsgs is set, kernelcapi logs controller and
application up and down events.

In addition, every registered CAPI controller has an associated traceflag
parameter controlling how CAPI messages sent from and to tha controller are
logged. The traceflag parameter is initialized with the value of the
showcapimsgs parameter when the controller is registered, but can later be
changed via the MANUFACTURER_REQ command KCAPI_CMD_TRACE.

If the value of traceflag is non-zero, CAPI messages are logged.
DATA_B3 messages are only logged if the value of traceflag is > 2.

If the lowest bit of traceflag is set, only the command/subcommand and message
length are logged. Otherwise, kernelcapi logs a readable representation of
the entire message.
