[PATCHv1 00/14] Bluetooth: Change socket lock to l2cap_chan lock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andrei Emeltchenko <andrei.emeltchenko@xxxxxxxxx>

Changing socket lock to L2CAP chan lock in L2CAP code. Needed for implementing
protocol above L2CAP without creating sockets.

Changes:
	* PATCHv1: Added extra line (per Gustavo comment)
	* RFCv6: Same code but patches 2,3 and 4 from RFCv5 are merged together
	following recommendations from review.
	* RFCv5: Fixed locking bug in l2cap_data_channel, added locks in 
	l2cap_sock_shutdown function, fixed several styles issues.
	* RFCv4: Better split patches so they looks more clear and obvious,
	taking coments about naming change and delete unused vars. See diff change
	from the previous version below:
	* RFCv3: Split the big patch to several small (I believe logical) chunks,
	remove unneded locks from cleanup_listen, use the same arguments for
	locked/unlocked socket error functions.
	* RFCv2: Convert l2cap channel list back to mutex from RCU list.

Andrei Emeltchenko (14):
  Bluetooth: trivial: Fix long line
  Bluetooth: Revert to mutexes from RCU list
  Bluetooth: Add l2cap_chan_lock
  Bluetooth: Add locked and unlocked state_change
