Bluetooth: af_bluetooth: Make BT_PKT_STATUS generic

2023-08-11T18:49:16+00:00

This makes the handling of BT_PKT_STATUS more generic so it can be reused by sockets other than SCO like BT_DEFER_SETUP, etc. Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Init sk_peer_* on bt_sock_alloc

2023-08-11T18:37:22+00:00

This makes sure peer information is always available via sock when using bt_sock_alloc. Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Consolidate code around sk_alloc into a helper function

2023-08-11T18:36:50+00:00

This consolidates code around sk_alloc into bt_sock_alloc which does take care of common initialization. Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Fix not cleanup led when bt_init fails

2022-12-02T21:09:31+00:00

bt_init() calls bt_leds_init() to register led, but if it fails later, bt_leds_cleanup() is not called to unregister it. This can cause panic if the argument "bluetooth-power" in text is freed and then another led_trigger_register() tries to access it: BUG: unable to handle page fault for address: ffffffffc06d3bc0 RIP: 0010:strcmp+0xc/0x30 Call Trace: led_trigger_register+0x10d/0x4f0 led_trigger_register_simple+0x7d/0x100 bt_init+0x39/0xf7 [bluetooth] do_one_initcall+0xd0/0x4e0 Fixes: e64c97b53bc6 ("Bluetooth: Add combined LED trigger for controller power") Signed-off-by: Chen Zhongjin Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Add BTPROTO_ISO socket type

2022-07-23T00:13:39+00:00

This introduces a new socket type BTPROTO_ISO which can be enabled with use of ISO Socket experiemental UUID, it can used to initiate/accept connections and transfer packets between userspace and kernel similarly to how BTPROTO_SCO works: Central -> uses connect with address set to destination bdaddr: > tools/isotest -s 00:AA:01:00:00:00 Peripheral -> uses listen: > tools/isotest -d Signed-off-by: Luiz Augusto von Dentz

net: SO_RCVMARK socket option for SO_MARK with recvmsg()

2022-04-28T20:08:15+00:00

Adding a new socket option, SO_RCVMARK, to indicate that SO_MARK should be included in the ancillary data returned by recvmsg(). Renamed the sock_recv_ts_and_drops() function to sock_recv_cmsgs().

net: remove noblock parameter from skb_recv_datagram()

2022-04-06T12:45:26+00:00

skb_recv_datagram() has two parameters 'flags' and 'noblock' that are merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)' As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags' into 'flags' and 'noblock' with finally obsolete bit operations like this: skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc); And this is not even done consistently with the 'flags' parameter. This patch removes the obsolete and costly splitting into two parameters and only performs bit operations when really needed on the caller side. One missing conversion thankfully reported by kernel test robot. I missed to enable kunit tests to build the mctp code.

Bluetooth: fix incorrect nonblock bitmask in bt_sock_wait_ready()

Callers pass msg->msg_flags as flags, which contains MSG_DONTWAIT instead of O_NONBLOCK. Signed-off-by: Gavin Li Signed-off-by: Marcel Holtmann
