Marcel Holtmann d79f34e32b Bluetooth: Use new hci_skb_pkt_* wrappers for core packet handling
The new hci_skb_pkt_* wrappers only help if they are used consistently
in the Bluetooth subsystem. So first convert the core packet handling.

Ivan Vecera d37b4c0a36 be2net: remove local variable 'status'
The lancer_cmd_get_file_len() uses lancer_cmd_read_object() to get
the current size of registers for ethtool registers dump. Returned status
value is stored but not checked. The check itself is not necessary as
the data_read output variable is initialized to 0 and status variable
can be removed.

This reverts commit 00ee592717 ("net: fix __netdev_update_features return
on ndo_set_features failure")
and adds a comment explaining why it's okay to return a value other than
0 upon error. Some drivers might actually change flags and return an
error so it's better to fire a spurious notification rather than miss
these.

Hannes Frederic Sowa a3a116e04c af_unix: take receive queue lock while appending new skb
While possibly in future we don't necessarily need to use
sk_buff_head.lock this is a rather larger change, as it affects the
af_unix fd garbage collector, diag and socket cleanups. This is too much
for a stable patch.

For the time being grab sk_buff_head.lock without disabling bh and irqs,
so don't use locked skb_queue_tail.

Yang Shi ec0738db8d arm64: bpf: make BPF prologue and epilogue align with ARM64 AAPCS
Save and restore FP/LR in BPF prog prologue and epilogue, save SP to FP
in prologue in order to get the correct stack backtrace.

However, ARM64 JIT used FP (x29) as eBPF fp register, FP is subjected to
change during function call so it may cause the BPF prog stack base address
change too.

Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee
saved register, so it will keep intact during function call.
It is initialized in BPF prog prologue when BPF prog is started to run
everytime. Save and restore x25/x26 in BPF prologue and epilogue to keep
them intact for the outside of BPF. Actually, x26 is unnecessary, but SP
requires 16 bytes alignment.

So, the BPF stack layout looks like:

                                 high
         original A64_SP =>   0:+-----+ BPF prologue
                                |FP/LR|
         current A64_FP =>  -16:+-----+
                                | ... | callee saved registers
                                +-----+
                                |     | x25/x26
         BPF fp register => -80:+-----+
                                |     |
                                | ... | BPF prog stack
                                |     |
                                |     |
         current A64_SP =>      +-----+
                                |     |
                                | ... | Function call stack

Pass a **skb to ipvlan_rcv_frame so that if skb_share_check returns a
new skb, we actually use it during further processing.

It's safe to ignore the new skb in the ipvlan_xmit_* functions, because
they call ipvlan_rcv_frame with local == true, so that dev_forward_skb
is called and always takes ownership of the skb.
