Bluetooth: add hci_lookup_le_connect

2015-08-10T19:36:13+00:00

This patch adds hci_lookup_le_connect method, that will be used to check
wether outgoing le connection attempt is in progress.

Bluetooth: Add second hci_request callback option for full skb

2015-04-02T14:09:27+00:00

This patch adds a second possible callback for HCI requests where the
callback will receive the full skb of the last successfully completed
HCI command. This API is useful for cases where we want to use a request
to read some data and the existing hci_event.c handlers do not store it
e.g. in the hci_dev struct.

The reason the patch is a bit bigger than just adding the new API is
because the hci_req_cmd_complete() functions required some refactoring
to enable it: now hci_req_cmd_complete() is simply used to request the
callback pointers if any, and the actual calling of them happens from a
single place at the end of hci_event_packet(). The reason for this is
that we need to pass the original skb (without any skb_pull, etc
modifications done to it) and it's simplest to keep track of it within
the hci_event_packet() function.

Bluetooth: Refactor HCI request variables into own struct

2015-03-30T21:20:53+00:00

In order to shrink the size of bt_skb_cb, this patch moves the HCI
request related variables into their own req_ctrl struct. Additionall
the L2CAP and HCI request structs are placed inside the same union since
they will never be used at the same time for the same skb.

Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flags

2015-03-13T17:28:36+00:00

With the extension of hdev->dev_flags utilizing a bitmap now, the space
is no longer restricted. Merge the hdev->dbg_flags into hdev->dev_flags
to save space on 64-bit architectures. On 32-bit architectures no size
reduction happens.

Bluetooth: Introduce hci_dev_test_and_clear_flag helper macro

2015-03-13T10:09:32+00:00

Instead of manually coding test_and_clear_bit on hdev->dev_flags all the
time, use hci_dev_test_and_clear_flag helper macro.

net: bluetooth: compact struct bt_skb_cb by converting boolean fields to bit fields

2015-03-02T05:19:29+00:00

Convert boolean fields incoming and req_start to bit fields and move
force_active in order save space in bt_skb_cb in an effort to use
a portion of skb->cb[] for storing skb->dropcount.

net: bluetooth: compact struct bt_skb_cb by inlining struct hci_req_ctrl

2015-03-02T05:19:29+00:00

struct hci_req_ctrl is never used outside of struct bt_skb_cb;
Inlining it frees 8 bytes on a 64 bit system in skb->cb[] allowing
the addition of more ancillary data.

Bluetooth: Add opcode parameter to hci_req_complete_t callback

2015-01-12T09:16:31+00:00

When hci_req_run() calls its provided complete function and one of the
HCI commands in the sequence fails, then provide the opcode of failing
command. In case of success HCI_OP_NOP is provided since all commands
completed.

This patch fixes the prototype of hci_req_complete_t and all its users.
