Johan Hedberg b6ae8457ac Bluetooth: Rename HCI_PAIRABLE to HCI_BONDABLE
The HCI_PAIRABLE flag isn't actually controlling whether we're pairable
but whether we're bondable. Therefore, rename it accordingly.

Johan Hedberg 6f78fd4bb9 Bluetooth: Fix check for connected state when pairing
Both BT_CONNECTED and BT_CONFIG state mean that we have a baseband link
available. We should therefore check for either of these when pairing
and deciding whether to call hci_conn_security() directly.

Johan Hedberg 616d55be4c Bluetooth: Fix SMP context tracking leading to a kernel crash
The HCI_CONN_LE_SMP_PEND flag is supposed to indicate whether we have an
SMP context or not. If the context creation fails, or some other error
is indicated between setting the flag and creating the context the flag
must be cleared first.

This patch ensures that smp_chan_create() clears the flag in case of
allocation failure as well as reorders code in smp_cmd_security_req()
that could lead to returning an error between setting the flag and
creating the context.

Without the patch the following kind of kernel crash could be observed
(this one because of unacceptable authentication requirements in a
Security Request):

Marcel Holtmann 66d8e837ab Bluetooth: Fix white list handling with resolvable private addresses
Devices using resolvable private addresses are required to provide
an identity resolving key. These devices can not be found using
the current controller white list support. This means if the kernel
knows about any devices with an identity resolving key, the white
list filtering must be disabled.

However so far the kernel kept identity resolving keys around even
for devices that are not using resolvable private addresses. The
notification to userspace clearly hints to not store the key and
so it is best to just remove the key from the kernel as well at
that point.

With this it easy now to detect when using the white list is
possible or when kernel side resolving of addresses is required.

Marcel Holtmann 8540f6c036 Bluetooth: Add support for using controller white list filtering
The Bluetooth controller can use a white list filter when scanning
to avoid waking up the host for devices that are of no interest.

Devices marked as reporting, direct connection (incoming) or general
connection are now added to the controller white list. The update of
the white list happens just before enabling passive scanning.

In case the white list is full and can not hold all devices, the
white list is not used and the filter policy set to accept all
advertisements.

Using the white list for scanning allows for power saving with
controllers that do not handle the duplicate filtering correctly.

Marcel Holtmann 4b9e7e7516 Bluetooth: Fix issue with ADV_IND reports and auto-connection handling
When adding remote devices to the kernel using the Add Device management
command, these devices are explicitly allowed to connect. This kind of
incoming connections are possible even when the controller itself is
not connectable.

For BR/EDR this distinction is pretty simple since there is only one
type of incoming connections. With LE this is not that simple anymore
since there are ADV_IND and ADV_DIRECT_IND advertising events.

The ADV_DIRECT_IND advertising events are send for incoming (slave
initiated) connections only. And this is the only thing the kernel
should allow when adding devices using action 0x01. This meaning
of incoming connections is coming from BR/EDR and needs to be
mapped to LE the same way.

Supporting the auto-connection of devices using ADV_IND advertising
events is an important feature as well. However it does not map to
incoming connections. So introduce a new action 0x02 that allows
the kernel to connect to devices using ADV_DIRECT_IND and in addition
ADV_IND advertising reports.

This difference is represented by the new HCI_AUTO_CONN_DIRECT value
for only connecting to ADV_DIRECT_IND. For connection to ADV_IND and
ADV_DIRECT_IND the old value HCI_AUTO_CONN_ALWAYS is used.

Marcel Holtmann cd4d567138 Bluetooth: Ignore ADV_DIRECT_IND attempts from unknown devices
Unconditionally connecting to devices sending ADV_DIRECT_IND when
the controller is in CONNECTABLE mode is a feature that is not
fully working. The background scanning trigger for this has been
removed, but the statement allowing it to happen in case some
other part triggers is still present. So remove that code part
as well to avoid unwanted connections.

Mark A. Greer bf30a67c94 NFC: digital: Add 'tg_listen_md' and 'tg_get_rf_tech' driver hooks
The digital layer of the NFC subsystem currently
supports a 'tg_listen_mdaa' driver hook that supports
devices that can do mode detection and automatic
anticollision.  However, there are some devices that
can do mode detection but not automatic anitcollision
so add the 'tg_listen_md' hook to support those devices.

In order for the digital layer to get the RF technology
detected by the device from the driver, add the
'tg_get_rf_tech' hook.  It is only valid to call this
hook immediately after a successful call to 'tg_listen_md'.

Vignesh Raman 32333edb82 Bluetooth: Avoid use of session socket after the session gets freed
The commits 08c30aca9e "Bluetooth: Remove
RFCOMM session refcnt" and 8ff52f7d04
"Bluetooth: Return RFCOMM session ptrs to avoid freed session"
allow rfcomm_recv_ua and rfcomm_session_close to delete the session
(and free the corresponding socket) and propagate NULL session pointer
to the upper callers.

Additional fix is required to terminate the loop in rfcomm_process_rx
function to avoid use of freed 'sk' memory.

The issue is only reproducible with kernel option CONFIG_PAGE_POISONING
enabled making freed memory being changed and filled up with fixed char
value used to unmask use-after-free issues.

reorder code did not account for that which made
it practically unusable with drivers using

The NULL pointer access could happen when ieee80211_crypto_hw_decrypt

1. rx->key->conf.cipher is not WEP, CCMP, TKIP or AES_CMAC
2. rx->sta is NULL

When ieee80211_crypto_hw_decrypt is called, it verifies
rx->sta->cipher_scheme and it will cause Oops if rx->sta is NULL.

This path adds an addirional rx->sta == NULL verification in
ieee80211_crypto_hw_decrypt for this case.

Since "wireless-regdb: remove antenna gain" was merged in the
wireless-regdb tree, the awk script parser has been incompatible
with the 'official' regulatory database.  This fixes that up.
Without this change the max EIRP is set to 0 making 802.11 devices
useless.

The fragile nature of the awk parser must be replaced, but ideas
over how to do that in the most scalable way are being reviewed.
In the meantime update the documentation for CFG80211_INTERNAL_REGDB
