Socket security shall be based on flags passed from HAL.
Android public API uses both encrypt and auth flags for "secure"
sockets which should be mapped to high security on our side, but since
this would also trigger requirement for 16-digits pin code (which is
not used in Android) we'll ignore auth flag and use either low or
medium security based on encrypt flag value only.
This patch adds entry for HF AG profile in built-in profiles list. This
it to reserve channel number so it's not assigned to other service
registered by application. Method for creating SDP record is not
provided so it's not possible for application to register HF AG service
by mistake (this can be only done by handsfree profile implementation).
This patch adds support to register server with channel number assigned
dynamically, i.e. first free number is assigned. Channels which are
reserved for built-in services are not assigned for other services.
Since there is only small, fixed number of channels to allocate for
RFCOMM servers we can store them in static array. This will make
lookup for free channel simpler once we add support to assign channel
numbers dynamically.
At startup, channels reserved for built-in services which have static
channel number are marked as reserved so they cannot be assigned for
other service.
Records are now created using helper function which creates SDP record
with common contents like service class, name and protocols. Other
attributes are then added by custom functions.
This patch makes logging more consistent by including rfsock pointer in
most messages which identifies socket structure unambigously (instead
of using bunch of file descriptors for the same purpose) and puts other
parameters in order in some cases.
Additionally, some new logs are introduced to better track socket
structures and connections lifetime.
This patch changes names of symbols related to various sockets to be
consistent and easier to follow in code.
Symbols related to actual BT (RFCOMM) socket are prefixed with "bt_".
Symbols related to local socket for Java comm are prefixed with "jv_".
Remote socket for Java comm is called "hal_sock".
This reduce logic in HAL to bare minimum e.g. no modifications in
library will be needed to add different socket type support.
Both bdaddr2str and btuuid2str handle NULL pointers so it is safe to
print debug unconditionally.

Theres no HAL API exposed to application to register different MAS
instances. Android 4.4 does support only MAS SMS. All Instance ID,
supported msg type and rfcomm channel are hardcoded in the stack.
Unfortunatelly we need to do the same way and wait for new HAL API
which is expected.
Add watch for tracking events from Android framework for server socket.
Android might want to close server connection, in this case we close
our listening socket and cleaning up rfsock structure. Glib watch is
added with high priority to avoid races.
Since Socket HAL allows us to specify RFCOMM channel number and directly
connect refactor send function to allow connect directly is uuid is zero
and channel number is specified.
We close file descriptors in cleanup_rfsock() and leaving the default
value gives us glib warnings if we close fd already and got G_IO_NVAL in
server_cb from bt_io.
This cleans up rfsock structures closing all sockets and making general
cleanup for servers and for connections. This will be called form socket
unregister.
Since we close all file descriptors in cleanup_rfsock do not close it also
during iochannel cleaning up. The flag was setup in bt_io_listen and
bt_io_connect calls.
Remove debug messages when sending data, debug still exist for connection
establishment. Do not print error when connection hang up, print debug
instead.
This adds SDP service record like shown below:
Service Name: OBEX Phonebook Access Server
Service RecHandle: 0x10002
Service Class ID List:
"Phonebook Access - PSE" (0x112f)
Protocol Descriptor List:
"RFCOMM" (0x0003)
Channel: 15
"OBEX" (0x0008)
Profile Descriptor List:
"Phonebook Access" (0x1130)
Version: 0x0100
This adds SDP record for OPP shown below:
Service Name: OBEX Object Push
Service RecHandle: 0x10002
Service Class ID List:
"OBEX Object Push" (0x1105)
Protocol Descriptor List:
"RFCOMM" (0x0003)
Channel: 9
"OBEX" (0x0008)
Profile Descriptor List:
"OBEX Object Push" (0x1105)
Version: 0x0100
