2022-07-23Bluetooth: Add initial implementation of BIS connectionsLuiz Augusto von Dentz1-0/+1

2022-03-04Bluetooth: Improve skb handling in mgmt_device_connected()Radoslaw Biernacki1-0/+15
This patch introduce eir_skb_put_data() that can be used to simplify operations on eir in goal of eliminating the necessity of intermediary buffers. eir_skb_put_data() is in pair to what eir_append_data() does with help of eir_len, but without awkwardness when passing return value to skb_put() (as it returns updated offset not size).

2022-03-04Bluetooth: Fix skb allocation in mgmt_remote_name() & mgmt_device_connected()Radoslaw Biernacki1-0/+5
This patch fixes skb allocation, as lack of space for ev might push skb tail beyond its end. Also introduce eir_precalc_len() that can be used instead of magic numbers for similar eir operations on skb.

2021-12-29net: Don't include filter.h from net/sock.hJakub Kicinski1-0/+2
sock.h is pretty heavily used (5k objects rebuilt on x86 after it's touched). We can drop the include of filter.h from it and add a forward declaration of struct sk_filter instead. This decreases the number of rebuilt objects when bpf.h is touched from ~5k to ~1k. There's a lot of missing includes this was masking. Primarily in networking tho, this time.
