[ Upstream commit cca342d98bef68151a80b024f7bf5f388d1fbdea ]
A different wait queue was used when removing ctrl_wait than when adding
it. This effectively made the remove operation without locking compared
to other operations on the wait queue ctrl_wait was part of. This caused
issues like below where dead000000000100 is LIST_POISON1 and
dead000000000200 is LIST_POISON2.
list_add corruption. next->prev should be prev (ffffffc1b0a33a08), \
but was dead000000000200. (next=ffffffc03ac77de0).

[ Upstream commit e04480920d1eec9c061841399aa6f35b6f987d8b ]
syzbot is hitting might_sleep() warning at hci_sock_dev_event() due to
calling lock_sock() with rw spinlock held [1].
It seems that history of this locking problem is a trial and error.
Commit b40df5743e ("[PATCH] bluetooth: fix socket locking in
hci_sock_dev_event()") in 2.6.21-rc4 changed bh_lock_sock() to
lock_sock() as an attempt to fix lockdep warning.
Then, commit 4ce61d1c7a ("[BLUETOOTH]: Fix locking in
hci_sock_dev_event().") in 2.6.22-rc2 changed lock_sock() to
local_bh_disable() + bh_lock_sock_nested() as an attempt to fix the
sleep in atomic context warning.
Then, commit 4b5dd696f8 ("Bluetooth: Remove local_bh_disable() from
hci_sock.c") in 3.3-rc1 removed local_bh_disable().
Then, commit e305509e678b ("Bluetooth: use correct lock to prevent UAF
of hdev object") in 5.13-rc5 again changed bh_lock_sock_nested() to
lock_sock() as an attempt to fix CVE-2021-3573.
This difficulty comes from current implementation that
hci_sock_dev_event(HCI_DEV_UNREG) is responsible for dropping all
references from sockets because hci_unregister_dev() immediately
reclaims resources as soon as returning from
hci_sock_dev_event(HCI_DEV_UNREG).
But the history suggests that hci_sock_dev_event(HCI_DEV_UNREG) was not
doing what it should do.
Therefore, instead of trying to detach sockets from device, let's accept
not detaching sockets from device at hci_sock_dev_event(HCI_DEV_UNREG),
by moving actual cleanup of resources from hci_unregister_dev() to
hci_cleanup_dev() which is called by bt_host_release() when all
references to this unregistered device (which is a kobject) are gone.
Since hci_sock_dev_event(HCI_DEV_UNREG) no longer resets
hci_pi(sk)->hdev, we need to check whether this device was unregistered
and return an error based on HCI_UNREGISTER flag. There might be subtle
behavioral difference in "monitor the hdev" functionality; please report
if you found something went wrong due to this patch.

it is remote device that is providing bogus data there is no
need to report this as error.
Since real_len variable was used only to allow conditional error
message it is now also removed.

The hci_sock_dev_event() function will cleanup the hdev object for
sockets even if this object may still be in used within the
hci_sock_bound_ioctl() function, result in UAF vulnerability.
This patch replace the BH context lock to serialize these affairs

commit 6a137caec23aeb9e036cdfd8a46dd8a366460e5d upstream.
In the cleanup routine for failed initialization of HCI device,
the flush_work(&hdev->rx_work) need to be finished before the
flush_work(&hdev->cmd_work). Otherwise, the hci_rx_work() can
possibly invoke new cmd_work and cause a bug, like double free,
in late processings.
This was assigned CVE-2021-3564.
This patch reorder the flush_work() to fix this bug.

commit 8da3a0b87f4f1c3a3bbc4bfb78cf68476e97d183 upstream.
When cmtp_attach_device fails, cmtp_add_connection returns the error value
which leads to the caller to doing fput through sockfd_put. But
cmtp_session kthread, which is stopped in this path will also call fput,
leading to a potential refcount underflow or a use-after-free.
Add a refcount before we signal the kthread to stop. The kthread will try
to grab the cmtp_session_sem mutex before doing the fput, which is held
when get_file is called, so there should be no races there.

Currently l2cap_chan_set_defaults() reset chan->conf_state to zero.
However, there is a flag CONF_NOT_COMPLETE which is set when
creating the l2cap_chan. It is suggested that the flag should be
cleared when l2cap_chan is ready, but when l2cap_chan_set_defaults()
is called, l2cap_chan is not yet ready. Therefore, we must set this
flag as the default.

commit 5c4c8c9544099bb9043a10a5318130a943e32fc3 upstream.
hci_chan can be created in 2 places: hci_loglink_complete_evt() if
it is an AMP hci_chan, or l2cap_conn_add() otherwise. In theory,
Only AMP hci_chan should be removed by a call to
hci_disconn_loglink_complete_evt(). However, the controller might mess
up, call that function, and destroy an hci_chan which is not initiated
by hci_loglink_complete_evt().
This patch adds a verification that the destroyed hci_chan must have
been init'd by hci_loglink_complete_evt().

commit e7c6e405e171fb33990a12ecfd14e6500d9e5cf2 upstream.
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".
Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).
This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.
At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ Upstream commit 219991e6be7f4a31d471611e265b72f75b2d0538 ]
Some devices, e.g. the RTL8723BS bluetooth part, some USB attached devices,
completely drop from the bus on a system-suspend. These devices will
have their driver unbound and rebound on resume (when the dropping of
the bus gets detected) and will show up as a new HCI after resume.
These devices do not benefit from the suspend / resume handling work done
by the hci_suspend_notifier. At best this unnecessarily adds some time to
the suspend/resume time. But this may also actually cause problems, if the
code doing the driver unbinding runs after the pm-notifier then the
hci_suspend_notifier code will try to talk to a device which is now in
an uninitialized state.
This commit adds a new HCI_QUIRK_NO_SUSPEND_NOTIFIER quirk which allows
drivers to opt-out of the hci_suspend_notifier when they know beforehand
that their device will be fully re-initialized / reprobed on resume.

During controller initialization, an LE Set RPA Timeout command is sent
to the controller if supported. However, the value checked to determine
if the command is supported is incorrect. Page 1921 of the Bluetooth

field corresponds to the LE Set RPA Timeout command, but currently
bit 6 of octet 35 is checked. This patch checks the correct value
instead.
This issue led to the error seen in the following btmon output during

from completing.

During system powercycle when trying to get the random address
hci_get_random_address set own_addr_type as 0x01. In which if we enable
ll_privacy it is supposed to be 0x03.

Currently the code auto-creates hci_conn only if the remote address has
been discovered before. This may not be the case. For example, the
remote device may trigger connection after reboot at already-paired
state so there is no inquiry result found, but it is still correct to
create the hci_conn when Connection Complete event is received.
A better guard is to check against bredr allowlist. Devices in the
allowlist have been given permission to auto-connect.
