[PATCHv5 00/19] Socket HAL

[PATCHv5 00/19] Socket HAL

[Andrei Emeltchenko]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

This is initial code implementing socket HAL. OPP currently works with send/receive files. Probaly
other profiles works as well, not tested yet.

Changes:
	* v5: Changed uuid_to_chan table to profile table keeping information about profile like: channel, create_record,
	svc_hint and sec_level.
	* v4: Changed name rfslot -> rfsock following Johan's comment and other cosmetic changes, fixed one bug in SDP
	record, use NULL instead of 0 for sdp functions.
	* v3: Fixed coding style with write/send between file descriptors.
	* v2: Following Marcel comments changed way copying between file descriptors works, added SDP record
	for OPP and now it is possible to send files through GUI. Merged one patch with structures with actual user.
	* v1: Rebased and use static src address, hal_fd removed from structure and closed after sent to framework,
	added connect calls and SDP parsing, added cleanup_rfcomm function, minor fixes.
	* RFC Initial

TODO:
	* Use sec_level / check what to do with Android supplied security flags.
	* Use splice() (requires bionic change first)

For tracking rfcomm sockets I use structure rfslot which has following
fields:
 - real_sock - real RFCOMM socket
 - fd - fd to communicate with Android framework

create_rfslot sets hal_fd which is fd passed to Android framework with CMSG

Andrei Emeltchenko (19):
  android/hal-sock: Print bdaddr string instead of pointer
  android/socket: Add get RFCOMM default channel
  android/socket: Define structs and implement listen
  android/socket: Implement socket accepted event
  android/socket: Implement Android RFCOMM stack events
  android/socket: Implement RFCOMM events
  android/socket: Send accept signal to Android through hal_fd
  android/socket: Write channel to Android fd
  android/socket: Implement socket connect HAL method
  android/socket: Parse SDP response and connect
  android/socket: Implement HAL connect call
  android/socket: Send RFCOMM channel to framework
  android/socket: Send connect signal on connect

  android/socket: Add SDP record for OPP profile
  android/socket: Add MAS uuid to profile table
  android/socket: Add SPP uuid to profile table
  android/socket: Add PBAP SDP record
  android/socket: Add SPP SDP record

[PATCHv5 03/19] android/socket: Define structs and implement listen

[Andrei Emeltchenko]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

This defines structures for socket HAL. We need to emulate Android
sockets by sending connect/accept signals over file descriptor.
Handle HAL socket listen call. Create RFCOMM socket and wait for events.
