* | Bluetooth: /proc/net/ entries for bluetooth protocolsMasatake YAMATO2012-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lsof command can tell the type of socket processes are using. Internal lsof uses inode numbers on socket fs to resolve the type of sockets. Files under /proc/net/, such as tcp, udp, unix, etc provides such inode information. Unfortunately bluetooth related protocols don't provide such inode information. This patch series introduces /proc/net files for the protocols. This patch against af_bluetooth.c provides facility to the implementation of protocols. This patch extends bt_sock_list and introduces two exported function bt_procfs_init, bt_procfs_cleanup. The type bt_sock_list is already used in some of implementation of protocols. bt_procfs_init prepare seq_operations which converts protocol own bt_sock_list data to protocol own proc entry when the entry is accessed. What I, lsof user, need is just inode number of bluetooth socket. However, people may want more information. The bt_procfs_init takes a function pointer for customizing the show handler of seq_operations. In v4 patch, __acquires and __releases attributes are added to suppress sparse warning. Suggested by Andrei Emeltchenko. In v5 patch, linux/proc_fs.h is included to use PDE. Build error is reported by Fengguang Wu.

* Bluetooth: Use tx window from config response for ack timingMat Martineau2012-07-15
| | | | | | | | | | | | | | | | | | | | | | | This change addresses an L2CAP ERTM throughput problem when a remote device does not fully utilize the available transmit window. The L2CAP ERTM transmit window size determines the maximum number of unacked frames that may be outstanding at any time. It is configured separately for each direction of an ERTM connection. Each side sends a configuration request with a tx_win field indicating how many unacked frames it is capable of receiving before sending an ack. The configuration response's tx_win field shows how many frames the transmitter will actually send before waiting for an ack. It's important to trace both the actual transmit window (to check for validity of incoming frames) and the number of frames that the transmitter will send before waiting (to send acks at the appropriate time). Now there are separate tx_win and ack_win values. ack_win is updated based on configuration responses, and is used to determine when acks are sent.

* | Bluetooth: Fix early return from l2cap_chan_delMat Martineau2012-06-04
|/ | | | | | | | | | | | | | | | | | | This fixes a regression from commit 2ead70b8390d199ca04cd35311b51f5f3676079e that is present in all kernels starting at v3.0. When L2CAP information was moved to struct l2cap_chan, a check was added to l2cap_chan_del to avoid certain cleanup operations when ERTM or streaming mode had not yet been initialized. The logic in the check did not take in to account that chan->conf_state is set to 0 in l2cap_chan_ready, so l2cap_chan_del failed to cancel timers and leaked memory any time the ERTM queues or lists were not empty. This change makes sure that l2cap_chan_del only returns early if ERTM initialization was not performed.
