When the connection attempt fails, the address information are not
provided in the HCI_LE_Connection_Complete event. So use the original
information from the connection to reconstruct the identity address.
This is important when a connection attempt has been made using the
identity address, but the cached resolvable random address has changed
in the meantime. The failure event needs to use the identity address
and not the resolvable random address.

When reporting connect failed events to userspace, use the address
of the connection and not the address from the HCI event.
This change is strictly speaking not needed since BR/EDR does not
have the concept of resolvable random addresses. It is more for
making the code consistent.

When the remote device has been successfully connected, report the
identity address (public address or static random address).
Currently the address from the HCI_LE_Connection_Complete event is
used. This was no problem so far, but since now known resolvable
random addresses are converted into identities, it is important to
use the identity of the connection and not the address report by
HCI event.

Whenever a device uses an RPA we want to have user space identify it by
its Identity Address if we've got an IRK available for it. This patch

We need to check whether there's a matching IRK and RPA when we're
requested to connect to a remote LE device based on its Identity
Address. This patch updates the hci_connect_le function to do an extra
call to hci_find_irk_by_addr and uses the RPA if it's cached. This is
particularly important once we start exposing the Identity Address to
user space instead of the RPA in events such as Device Connected and
Device Found.

Identity Addresses are either public or static random. When looking up
addresses based on the Identity Address it doesn't make sense to go
through the IRK list if we're given a private random address. This patch
fixes (or rather improves) the hci_find_irk_by_addr function to bail out
early if given a private random address.

When we initiate pairing through mgmt_pair_device the code has so far
been waiting for a successful HCI Encrypt Change event in order to
respond to the mgmt command. However, putting privacy into the play we
actually want the key distribution to be complete before replying so
that we can include the Identity Address in the mgmt response.
This patch updates the various hci_conn callbacks for LE in mgmt.c to
only respond in the case of failure, and adds a new mgmt_smp_complete
function that the SMP code will call once key distribution has been
completed.
Since the smp_chan_destroy function that's used to indicate completion
and clean up the SMP context can be called from various places,
including outside of smp.c, the easiest way to track failure vs success
is a new flag that we set once key distribution has been successfully
completed.

When we receive a remote identity address during SMP key distribution we
should ensure that any associated L2CAP channel instances get their
address information correspondingly updated (so that e.g. doing
getpeername on associated sockets returns the correct address).
This patch adds a new L2CAP core function l2cap_conn_update_id_addr()
which is used to iterate through all L2CAP channels associated with a

Since we want user space to see and use the LE Identity Address whenever
interfacing with the kernel it makes sense to track that instead of the
real address (the two will only be different in the case of an RPA).

Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI
driver) added the module alias to hci_vhci module so it's possible to
create the /dev/vhci node. However creating an alias without
specifying the minor doesn't allow us to create the node ahead,
triggerring module auto-load when it's first accessed.
Starting with depmod from kmod 16 we started to warn if there's a
devname alias without specifying the major and minor.
Let's do the same done for uhid, kvm, fuse and others, specifying a
fixed minor. In systems with systemd as the init the following will
happen: on early boot systemd will call "kmod static-nodes" to read
/lib/modules/$(uname -r)/modules.devname and then create the nodes. When
first accessed these "dead" nodes will trigger the module loading.

The skb truesize of a 12-byte payload with a 10-byte head/tail
reserve is 768 bytes. Consequently, even with 40 tx_credits, at
most 6 packets could be queued at any one time:
40 tx_credits * 127-byte mtu < 768-byte truesize * 7
This error could also cause the tx queue to apparently stall if
credit flow control is disabled (where tx_credits is fixed at 5),
or if the receiver only granted a limited number of tx credits
(eg., less than 7).
Instead, track the outstanding number of queued packets not yet sent
in wmem_alloc and allow for a maximum of 40 queued packets. Report
the space avail for a single write() as the mtu * number of packets
left before reaching the maximum.

the dlc state_change(BT_CONNECTED) notification is received.
However, if the dlc from the RFCOMM socket is being reused

and no notification will occur.
Instead, always parent the RFCOMM tty device to the acl link

| hci_dev_put
| hci_conn_put
| put_device (last reference)
| bt_link_release
| kfree(conn)
return p << just freed |
Even if a hci_conn reference were taken (via hci_conn_get), would
not guarantee the lifetime of the sysfs device, but only safe
access to the in-memory structure.
