* Bluetooth: Implement support for MeshBrian Gix2022-09-061-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds state bits, storage and HCI command chains for sending and receiving Bluetooth Mesh advertising packets, and delivery to requesting user space processes. It specifically creates 4 new MGMT commands and 2 new MGMT events: MGMT_OP_SET_MESH_RECEIVER - Sets passive scan parameters and a list of AD Types which will trigger Mesh Packet Received events MGMT_OP_MESH_READ_FEATURES - Returns information on how many outbound Mesh packets can be simultaneously queued, and what the currently queued handles are. MGMT_OP_MESH_SEND - Command to queue a specific outbound Mesh packet, with the number of times it should be sent, and the BD Addr to use. Discrete advertisments are added to the ADV Instance list. MGMT_OP_MESH_SEND_CANCEL - Command to cancel a prior outbound message request. MGMT_EV_MESH_DEVICE_FOUND - Event to deliver entire received Mesh Advertisement packet, along with timing information. MGMT_EV_MESH_PACKET_CMPLT - Event to indicate that an outbound packet is no longer queued for delivery.

* Bluetooth: mgmt: Introduce mgmt_alloc_skb and mgmt_send_event_skbLuiz Augusto von Dentz2021-12-071-17/+49
| | | | | | | | | | | This introduces mgmt_alloc_skb and mgmt_send_event_skb which are convenient when building MGMT events that have variable length as the likes of skb_put_data can be used to insert portion directly on the skb instead of having to first build an intermediate buffer just to be copied over the skb.

* networking: make skb_push & __skb_push return void pointersJohannes Berg2017-06-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) @@ expression SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - fn(SKB, LEN)[0] + *(u8 *)fn(SKB, LEN) Note that the last part there converts from push(...)[0] to the more idiomatic *(u8 *)push(...).

* networking: make skb_put & friends return void pointersJohannes Berg2017-06-161-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* networking: introduce and use skb_put_data()Johannes Berg2017-06-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this.

* Bluetooth: Add generic mgmt helper APIJohan Hedberg2015-03-171-0/+210
There are several mgmt protocol features that will be needed by more than just the current HCI_CHANNEL_CONTROL. These include sending generic events as well as handling pending commands. This patch moves these functions out from mgmt.c to a new mgmt_util.c file. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
