Subject: [PATCHv7 00/14] Socket HAL

From: Andrei Emeltchenko <[email protected]>

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

Changes:
* v7: Rebase and fixing missing unref. All needed SDP records for supported profiles are created.
Support listen() with specified channel like in bluedroid.
* v6: Use watch_id to remove source and general cleanup
* 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 (14):
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 to Android framework
android/socket: Close file descriptor after sending
android/socket: Add general service create/remove function
android/socket: Add OPP SDP record
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
android/socket: Support listen() with supplied chan number
android/hal-sock: Print bdaddr on connect
android/socket: Refactor socket send_fd function
