The current bitshift logic in idmap incorrectly uses
the literal 1 for the value to shift in idmap_alloc(),
idmap_take(), and idmap_alloc_next(). This causes the
resulting value to be an int instead of a long, which
results in the wrong bit being set once the number of
bits to shift operand exceeds sizeof(int). Also
on some platforms, the behavior of the left bitshift
operator is undefined when this overflow occurs.
As we won't allow any card to be registered when the kernel doesn't
support defer_setup, we don't need to have the listening SCO socket
open in this case.
If the kernel doesn't support defer_setup for SCO, we shouldn't allow
cards to be registered, because in that case we won't be able to
properly send the file descriptor to the Agent.
So the value might be used directly for D-Bus property emission.
Otherwise D-Bus asserts and screws itself with:
ofonod[7427]: src/sms.c:handle_mwi()
process 7427: arguments to dbus_message_iter_append_basic() were
incorrect, assertion "*bool_p == 0 || *bool_p == 1" failed in file
../../dbus/dbus-message.c line 2549.
It's not possible to be both greater than '9' and less than '0'. This
would lead to accepting things like "#$33#" as activation and "*$33#" as
deactivation, even though the string makes no sense.

In the case that ofono_handsfree_card_connect_sco() is called outside the
context of a .Connect() call, there's no message we need to reply. This
happens, for example, when the HFP AG plugin initiates a SCO connection when
it receives an AT+BCC command from the HF.
This patch extends SetProperty method of the Handsfree interface
allowing to disable echo canceling and noise reduction feature in
the audio gateway through a D-Bus method call. Once disabled, it
is not allowed to enable it using this procedure.
According to Bluetooth HFP spec: By default, if the AG supports its
own embedded echo canceling and/or noise reduction functions, it shall
have them activated until the AT+NREC command is received. The
configuration set by the HF shall by used by the AG while the Service
Level Connection is active.
Since there isn't a command to query the current value, it is being
assumed that Echo Canceling and Noise Reduction is enabled when the
connection is established and the gateway supports this feature.
HFP 1.6 adds a new feature called Codec Negotitation. For the HF Role,
this feature is stored in bit 8 of the supported features
bitmap.
This patch changes the range of valid HF feature bitmaps to 2^8-1.
Each time an agent registers itself, we check if we support deferred
setup and if the agent has mSBC as a codec, if both checks are true,
we enable wideband speech support.
'defer_setup' will be one of the inputs when enabling or disabling
support for wideband speech codecs, we will only enable wideband
speech support if the kernel supports deferred setup.
So, we have to have this information available, in this case it means
a global variable.
This patch removes the hard-coded CVSD codec, and adds the selected
codec in the NewConnection method call, notifying the agent the codec
previously selected for the audio connection.
This can be set by the modem driver to indicate that the device is
always in the online state when it is enabled. This is useful for
modem drivers that handle both CDMA and GSM devices.
When calling the card's .Connect() method, we should be able to
establish a SCO connection.
Right now, we only have support for establishing the SCO connection
directly, this is what is expected from HFP 1.5 HF/AG devices.
The Audio Card is being created when the NewConnection from BlueZ
Profile is received, and registered when the service level connection
negotiation finishes. This patch rejects SCO connection if the SCO
incoming connection arrives when the service level negotiation is
ongoing.
