Previous commit e04480920d1e ("Bluetooth: defer cleanup of resources
in hci_unregister_dev()") defers all destructive actions to
hci_release_dev() to prevent cocurrent problems like NPD, UAF.
However, there are still some exceptions that are ignored.
The smp_unregister() in hci_dev_close_sync() (previously in
hci_dev_do_close) will release resources like the sensitive channel
and the smp_dev objects. Consider the situations the device is detaching
or power down while the kernel is still operating on it, the following
data race could take place.
thread-A hci_dev_close_sync | thread-B read_local_oob_ext_data
|
hci_dev_unlock() |
... | hci_dev_lock()
if (hdev->smp_data) |
chan = hdev->smp_data |
| chan = hdev->smp_data (3)
|
hdev->smp_data = NULL (1) | if (!chan || !chan->data) (4)
... |
smp = chan->data | smp = chan->data
if (smp) |
chan->data = NULL (2) |
... |
kfree_sensitive(smp) |
| // dereference smp trigger UFA
That is, the objects hdev->smp_data and chan->data both suffer from the
data races. In a preempt-enable kernel, the above schedule (when (3) is
before (1) and (4) is before (2)) leads to UAF bugs. It can be
reproduced in the latest kernel and below is part of the report:

To solve these data races, this patch places the smp_unregister()
function in the protected area by the hci_dev_lock(). That is, the
smp_unregister() function can not be concurrently executed when
operating functions (most of them are mgmt operations in mgmt.c) hold
the device lock.
This patch is tested with kernel LOCK DEBUGGING enabled. The price from
the extended holding time of the device lock is supposed to be low as the
smp_unregister() function is fairly short and efficient.

Pull signal/exit/ptrace updates from Eric Biederman:
"This set of changes deletes some dead code, makes a lot of cleanups
which hopefully make the code easier to follow, and fixes bugs found
along the way.
The end-game which I have not yet reached yet is for fatal signals
that generate coredumps to be short-circuit deliverable from
complete_signal, for force_siginfo_to_task not to require changing
userspace configured signal delivery state, and for the ptrace stops
to always happen in locations where we can guarantee on all
architectures that the all of the registers are saved and available on
the stack.
Removal of profile_task_ext, profile_munmap, and profile_handoff_task
are the big successes for dead code removal this round.
A bunch of small bug fixes are included, as most of the issues
reported were small enough that they would not affect bisection so I
simply added the fixes and did not fold the fixes into the changes
they were fixing.
There was a bug that broke coredumps piped to systemd-coredump. I
dropped the change that caused that bug and replaced it entirely with
something much more restrained. Unfortunately that required some
rebasing.
Some successes after this set of changes: There are few enough calls
to do_exit to audit in a reasonable amount of time. The lifetime of
struct kthread now matches the lifetime of struct task, and the
pointer to struct kthread is no longer stored in set_child_tid. The
flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
removed. Issues where task->exit_code was examined with
signal->group_exit_code should been examined were fixed.
There are several loosely related changes included because I am
cleaning up and if I don't include them they will probably get lost.

sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.
There's a lot of missing includes this was masking. Primarily
in networking tho, this time.
