Previously, capability was checked using capable(), which verified that the
caller of the ioctl system call had the required capability. In addition,
the result of the check would be stored in the HCI_SOCK_TRUSTED flag,
making it persistent for the socket.
However, malicious programs can abuse this approach by deliberately sharing
an HCI socket with a privileged task. The HCI socket will be marked as
trusted when the privileged task occasionally makes an ioctl call.
This problem can be solved by using sk_capable() to check capability, which
ensures that not only the current task but also the socket opener has the
specified capability, thus reducing the risk of privilege escalation
through the previously identified vulnerability.

Previously, channel open messages were always sent to monitors on the first
ioctl() call for unbound HCI sockets, even if the command and arguments
were completely invalid. This can leave an exploitable hole with the abuse
of invalid ioctl calls.
This commit hardens the ioctl processing logic by first checking if the
command is valid, and immediately returning with an ENOIOCTLCMD error code
if it is not. This ensures that ioctl calls with invalid commands are free
of side effects, and increases the difficulty of further exploitation by
forcing exploitation to find a way to pass a valid command first.

There are a number of bugs here:
1) If "count" is less than sizeof(dump_data.data) then it copies
uninitialized data.
2) If simple_write_to_buffer() returns -EFAULT then we run into a
problem "ret < count" comparison. "count" is an unsigned long so the
comparison is type promoted to unsigned long and the negative returns
become high positive values. That also results in copying
uninitialized data.
3) If "*ppos" is non-zero then the first part of the dump_data
buffer is uninitialized. Using copy_from_user() instead of
simple_write_to_buffer() is more appropriate here.

We can never assume the uart will deliver a complete packet to the BT
layer at once, the expected packet may be divided into several parts by
uart as uart doesn't know the received packet size, the received data
count may mismatch with the expected packet size, so here
is_valid_bootloader_signature() check may always return false.
Even we remove the count check in is_valid_bootloader_signature(), then
the first part of the data which includes the packet type can pass the
is_valid_bootloader_signature() check, but the remaining parts don't
have the packet type data still cannot pass the check, here return
directly will cause the data loss.
So need to remove the received bootloader signature check here, the
h4_recv_buf() can help us combine the different data received into one
packet. If any out-of-sync or incomplete bootloader signature is received,
it is safe to ignore and discard it, and process the next bootloader
signature.

On some devices the BCM Bluetooth adapter does not have a valid bdaddr set.
btbcm.c currently sets HCI_QUIRK_INVALID_BDADDR to indicate when this is
the case. But this requires users to manual setup a btaddr, by doing e.g.:
btmgmt -i hci0 public-addr 'B0:F1:EC:82:1D:B3'
Which means that Bluetooth will not work out of the box on such devices.
To avoid this (where possible) hci_bcm sets: HCI_QUIRK_USE_BDADDR_PROPERTY
which tries to get the bdaddr from devicetree.
But this only works on devicetree platforms. On UEFI based platforms
there is a special Broadcom UEFI variable which when present contains
the devices bdaddr, just like how there is another UEFI variable which
contains wifi nvram contents including the wifi MAC address.
Add support for getting the bdaddr from this Broadcom UEFI variable,
so that Bluetooth will work OOTB for users on devices where this
UEFI variable is present.
This fixes Bluetooth not working on for example Asus T100HA 2-in-1s.

Add devcoredump APIs to hci core so that drivers only have to provide
the dump skbs instead of managing the synchronization and timeouts.
The devcoredump APIs should be used in the following manner:
- hci_devcoredump_init is called to allocate the dump.
- hci_devcoredump_append is called to append any skbs with dump data
OR hci_devcoredump_append_pattern is called to insert a pattern.
- hci_devcoredump_complete is called when all dump packets have been
sent OR hci_devcoredump_abort is called to indicate an error and
cancel an ongoing dump collection.
The high level APIs just prepare some skbs with the appropriate data and
queue it for the dump to process. Packets part of the crashdump can be
intercepted in the driver in interrupt context and forwarded directly to
the devcoredump APIs.
Internally, there are 5 states for the dump: idle, active, complete,
abort and timeout. A devcoredump will only be in active state after it
has been initialized. Once active, it accepts data to be appended,
patterns to be inserted (i.e. memset) and a completion event or an abort
event to generate a devcoredump. The timeout is initialized at the same
time the dump is initialized (defaulting to 10s) and will be cleared
either when the timeout occurs or the dump is complete or aborted.
