Thanks. -Stefan
[Impact] lock_sock on bt_sock_recvmsg() from net/bluetooth/af_bluetooth.c may cause a deadlock. [Backport] Due to the lack of f4b41f062c42 ("net: remove noblock parameter from skb_recv_datagram()"), Jammy and Focal had a small context conflict. Focal also had another context conflict due to it not having b8ddc3b14c7a ("Bluetooth: fix indentation and alignment reported by checkpatch"). [Test] Compile tested. [Where problems could occur] Any issues here would direcly impact Bluetooth usage. [Other info] This is also a follow-up fix to CVE-2023-51779.
