2011-06-08Bluetooth: Allow unsegmented SDU retries on sock_queue_rcv_skb failureRuiyi Zhang
In L2CAP_SDU_UNSEGMENTED case, if sock_queue_rcv_skb returns error, l2cap_ertm_reassembly_sdu should not return 0 so as to insert the skb into BUSY_QUEUE for later retries. Signed-off-by: Ruiyi Zhang <Ruiyi.Zhang@Atheros.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-05-05Bluetooth: Remove l2cap_sk_listGustavo F. Padovan
A new list was added to replace the socket based one. This new list doesn't depent on sock and then fits better inside l2cap_core.c code. It also rename l2cap_chan_alloc() to l2cap_chan_create() and l2cap_chan_free() to l2cap_chan_destroy) Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-05-05Bluetooth: Handle psm == 0 case inside l2cap_add_psm()Gustavo F. Padovan
When the user doesn't specify a psm we have the choose one for the channel. Now we do this inside l2cap_add_psm(). Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-05-05Bluetooth: Add l2cap_add_psm() and l2cap_add_scid()Gustavo F. Padovan
The intention is to get rid of the l2cap_sk_list usage inside l2cap_core.c. l2cap_sk_list will soon be replaced by a list that does not depend on socket usage. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-04-14Bluetooth: Fix lockdep warning in L2CAPGustavo F. Padovan
Fix a regression from the L2CAP "rewrite" patches. Purge the tx_q already happens on l2cap_chan_del() so we don't need it at l2cap_disconnect_req(). Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-04-13Bluetooth: Add proper handling of received LE dataGustavo F. Padovan

2011-04-07Bluetooth: Use struct list_head for L2CAP channels listGustavo F. Padovan
Use a well known Kernel API is always a good idea than implement your own list. In the future we might use RCU on this list. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-04-07Bluetooth: Create struct l2cap_chanGustavo F. Padovan
struct l2cap_chan cames to create a clear separation between what properties and data belongs to the L2CAP channel and what belongs to the socket. By now we just fold the struct sock * in struct l2cap_chan as all the channel info is struct l2cap_pinfo today. In the next commits we will see a move of channel stuff to struct l2cap_chan.

2011-03-31Bluetooth: Increment unacked_frames count only the first transmitSuraj Sumangala
This patch lets 'l2cap_pinfo.unacked_frames' be incremented only the first time a frame is transmitted. Previously it was being incremented for retransmitted packets too resulting the value to cross the transmit window size. Signed-off-by: Suraj Sumangala <suraj@atheros.com> Signed-off-by: Gustavo F.

2011-03-31Bluetooth: check L2CAP info_rsp ident and stateAndrei Emeltchenko
Information requests/responses are unbound to L2CAP channel. Patch fixes issue arising when two devices connects at the same time to each other. This way we do not process out of the context messages. We are safe dropping info_rsp since info_timer is left running.

2011-03-31Bluetooth: Move bt_accept_enqueue() to outside __l2cap_chan_addGustavo F. Padovan
