b38db473f5 Bluetooth: L2CAP: export l2cap_chan_hold for modules
[ Upstream commit e060088db0bdf7932e0e3c2d24b7371c4c5b867c ]

l2cap_chan_put() is exported, so export also l2cap_chan_hold() for
modules.

l2cap_chan_hold() has use case in net/bluetooth/6lowpan.c

05d5df4913 Bluetooth: 6lowpan: Don't hold spin lock over sleeping functions
[ Upstream commit 98454bc812f3611551e4b1f81732da4aa7b9597e ]

disconnect_all_peers() calls sleeping function (l2cap_chan_close) under
spinlock.  Holding the lock doesn't actually do any good -- we work on a
local copy of the list, and the lock doesn't protect against peer->chan
having already been freed.

Fix by taking refcounts of peer->chan instead.  Clean up the code and
old comments a bit.

Take devices_lock instead of RCU, because the kfree_rcu();
l2cap_chan_put(); construct in chan_close_cb() does not guarantee
peer->chan is necessarily valid in RCU.

Also take l2cap_chan_lock() which is required for l2cap_chan_close().

9b1a83c678 Bluetooth: 6lowpan: fix BDADDR_LE vs ADDR_LE_DEV address type confusion
[ Upstream commit b454505bf57a2e4f5d49951d4deb03730a9348d9 ]

Bluetooth 6lowpan.c confuses BDADDR_LE and ADDR_LE_DEV address types,
e.g. debugfs "connect" command takes the former, and "disconnect" and
"connect" to already connected device take the latter.  This is due to
using same value both for l2cap_chan_connect and hci_conn_hash_lookup_le
which take different dst_type values.

Fix address type passed to hci_conn_hash_lookup_le().

Retain the debugfs API difference between "connect" and "disconnect"
commands since it's been like this since 2015 and nobody apparently
complained.

[ Upstream commit 3b78f50918276ab28fb22eac9aa49401ac436a3b ]

Bluetooth 6lowpan.c netdev has header_ops, so it must set link-local
header for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW

Add missing skb_reset_mac_header() for uncompressed ipv6 RX path.

For the compressed one, it is done in lowpan_header_decompress().

964cbb198f Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen()
[ Upstream commit 862c628108562d8c7a516a900034823b381d3cba ]

syzbot reported the splat below without a repro.

In the splat, a single thread calling bt_accept_dequeue() freed sk
and touched it after that.

The root cause would be the racy l2cap_sock_cleanup_listen() call
added by the cited commit.

bt_accept_dequeue() is called under lock_sock() except for
l2cap_sock_release().

Two threads could see the same socket during the list iteration
in bt_accept_dequeue():

  CPU1                        CPU2 (close())
  ----                        ----
  sock_hold(sk)               sock_hold(sk);
  lock_sock(sk)   <-- block close()
  sock_put(sk)
  bt_accept_unlink(sk)
    sock_put(sk)  <-- refcnt by bt_accept_enqueue()
  release_sock(sk)
                              lock_sock(sk)
                              sock_put(sk)
                              bt_accept_unlink(sk)
                                sock_put(sk)        <-- last refcnt
                              bt_accept_unlink(sk)  <-- UAF

Depending on the timing, the other thread could show up in the
"Freed by task" part.

Let's call l2cap_sock_cleanup_listen() under lock_sock() in
l2cap_sock_release().

[ Upstream commit 15bf2c6391bafb14a3020d06ec0761bce0803463 ]

This attempts to detect if HCI_EV_NUM_COMP_PKTS contain an unbalanced
(more than currently considered outstanding) number of packets otherwise
it could cause the hcon->sent to underflow and loop around breaking the
tracking of the outstanding packets pending acknowledgment.

In 'hci_conn_del_sysfs()', 'device_unregister()' may be called when
an underlying (kobject) reference counter is greater than 1. This
means that reparenting (happened when the device is actually freed)
is delayed and, during that delay, parent controller device (hciX)
may be deleted. Since the latter may create a dangling pointer to
freed parent, avoid that scenario by reparenting to NULL explicitly.

8d3dd53f92 Bluetooth: L2CAP: Fix attempting to adjust outgoing MTU
[ Upstream commit d24e4a7fedae121d33fb32ad785b87046527eedb ]

Configuration request only configure the incoming direction of the peer
initiating the request, so using the MTU is the other direction shall
not be used, that said the spec allows the peer responding to adjust:

Bluetooth Core 6.1, Vol 3, Part A, Section 4.5

 'Each configuration parameter value (if any is present) in an
 L2CAP_CONFIGURATION_RSP packet reflects an ‘adjustment’ to a
 configuration parameter value that has been sent (or, in case of
 default values, implied) in the corresponding
 L2CAP_CONFIGURATION_REQ packet.'

That said adjusting the MTU in the response shall be limited to ERTM
channels only as for older modes the remote stack may not be able to
detect the adjustment causing it to silently drop packets.

[ Upstream commit 6ef99c917688a8510259e565bd1b168b7146295a ]

This replaces the usage of HCI_ERROR_REMOTE_USER_TERM, which as the name
suggest is to indicate a regular disconnection initiated by an user,
with HCI_ERROR_AUTH_FAILURE to indicate the session has timeout thus any
pairing shall be considered as failed.

24a855e2bb Bluetooth: SMP: If an unallowed command is received consider it a failure
[ Upstream commit fe4840df0bdf341f376885271b7680764fe6b34e ]

If a command is received while a bonding is ongoing consider it a
pairing failure so the session is cleanup properly and the device is
disconnected immediately instead of continuing with other commands that
may result in the session to get stuck without ever completing such as
the case bellow:

> ACL Data RX: Handle 2048 flags 0x02 dlen 21
      SMP: Identity Information (0x08) len 16
        Identity resolving key[16]: d7e08edef97d3e62cd2331f82d8073b0
> ACL Data RX: Handle 2048 flags 0x02 dlen 21
      SMP: Signing Information (0x0a) len 16
        Signature key[16]: 1716c536f94e843a9aea8b13ffde477d
Bluetooth: hci0: unexpected SMP command 0x0a from XX:XX:XX:XX:XX:XX
> ACL Data RX: Handle 2048 flags 0x02 dlen 12
      SMP: Identity Address Information (0x09) len 7
        Address: XX:XX:XX:XX:XX:XX (Intel Corporate)

While accourding to core spec 6.1 the expected order is always BD_ADDR
first first then CSRK:

When using LE legacy pairing, the keys shall be distributed in the
following order:

    LTK by the Peripheral

    EDIV and Rand by the Peripheral

    IRK by the Peripheral

    BD_ADDR by the Peripheral

    CSRK by the Peripheral

    LTK by the Central

    EDIV and Rand by the Central

    IRK by the Central

    BD_ADDR by the Central

    CSRK by the Central

When using LE Secure Connections, the keys shall be distributed in the
following order:

    IRK by the Peripheral

    BD_ADDR by the Peripheral

    CSRK by the Peripheral

    IRK by the Central

    BD_ADDR by the Central

    CSRK by the Central

According to the Core 6.1 for commands used for key distribution "Key
Rejected" can be used:

  '3.6.1. Key distribution and generation

  A device may reject a distributed key by sending the Pairing Failed command
  with the reason set to "Key Rejected".

262cd18f5f Bluetooth: Fix null-ptr-deref in l2cap_sock_resume_cb()
[ Upstream commit a0075accbf0d76c2dad1ad3993d2e944505d99a0 ]

syzbot reported null-ptr-deref in l2cap_sock_resume_cb(). [0]

l2cap_sock_resume_cb() has a similar problem that was fixed by commit
1bff51ea59a9 ("Bluetooth: fix use-after-free error in lock_sock_nested()").

Since both l2cap_sock_kill() and l2cap_sock_resume_cb() are executed
under l2cap_sock_resume_cb(), we can avoid the issue simply by checking
if chan->data is NULL.

Let's not access to the killed socket in l2cap_sock_resume_cb().

397df6d957 Bluetooth: L2CAP: Fix L2CAP MTU negotiation
commit 042bb9603c44620dce98717a2d23235ca57a00d7 upstream.

OBEX download from iPhone is currently slow due to small packet size
used to transfer data which doesn't follow the MTU negotiated during
L2CAP connection, i.e. 672 bytes instead of 32767:

The MTUs are negotiated for each direction. In this traces 32767 for
iPhone->localhost and no MTU for localhost->iPhone, which based on
'4.4 L2CAP_CONFIGURATION_REQ' (Core specification v5.4, Vol. 3, Part
A):

  The only parameters that should be included in the
  L2CAP_CONFIGURATION_REQ packet are those that require different
  values than the default or previously agreed values.
  ...
  Any missing configuration parameters are assumed to have their
  most recently explicitly or implicitly accepted values.

and '5.1 Maximum transmission unit (MTU)':

  If the remote device sends a positive L2CAP_CONFIGURATION_RSP
  packet it should include the actual MTU to be used on this channel
  for traffic flowing into the local device.
  ...
  The default value is 672 octets.

is set by BlueZ to 672 bytes.

It seems that the iPhone used the lowest negotiated value to transfer
data to the localhost instead of the negotiated one for the incoming
direction.

This could be fixed by using the MTU negotiated for the other
direction, if exists, in the L2CAP_CONFIGURATION_RSP.
This allows to use segmented packets as in the following traces:

737f13ac66 Bluetooth: L2CAP: Fix not responding with L2CAP_CR_LE_ENCRYPTION
[ Upstream commit 03dba9cea72f977e873e4e60e220fa596959dd8f ]

Depending on the security set the response to L2CAP_LE_CONN_REQ shall be
just L2CAP_CR_LE_ENCRYPTION if only encryption when BT_SECURITY_MEDIUM
is selected since that means security mode 2 which doesn't require
authentication which is something that is covered in the qualification
test L2CAP/LE/CFC/BV-25-C.

4db9080b89 Bluetooth: hci_event: Fix sending MGMT_EV_DEVICE_FOUND for invalid address
[ Upstream commit eb73b5a9157221f405b4fe32751da84ee46b7a25 ]

This fixes sending MGMT_EV_DEVICE_FOUND for invalid address
(00:00:00:00:00:00) which is a regression introduced by
a2ec905d1e16 ("Bluetooth: fix kernel oops in store_pending_adv_report")
since in the attempt to skip storing data for extended advertisement it
actually made the code to skip the entire if statement supposed to send
MGMT_EV_DEVICE_FOUND without attempting to use the last_addr_adv which
is garanteed to be invalid for extended advertisement since we never
store anything on it.

b3d607e36f Bluetooth: Fix error code in chan_alloc_skb_cb()
[ Upstream commit 72d061ee630d0dbb45c2920d8d19b3861c413e54 ]

The chan_alloc_skb_cb() function is supposed to return error pointers on
error.  Returning NULL will lead to a NULL dereference.

a9a7672fc1 Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc
commit 5f397409f8ee5bc82901eeaf799e1cbc4f8edcf1 upstream.

A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.

Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.

Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

Fixes: 7c4f78cdb8e7 ("Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()")

f6ad641646 Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
[ Upstream commit 7c4f78cdb8e7501e9f92d291a7d956591bf73be9 ]

bt_sock_alloc() allocates the sk object and attaches it to the provided
sock object. On error l2cap_sock_alloc() frees the sk object, but the
dangling pointer is still attached to the sock object, which may create
use-after-free in other code.

37fb0fd3fb Bluetooth: Fix type of len in rfcomm_sock_getsockopt{,_old}()
commit 5fe6caa62b07fd39cd6a28acc8f92ba2955e11a6 upstream.

Commit 9bf4e919ccad worked around an issue introduced after an innocuous
optimisation change in LLVM main:

> len is defined as an 'int' because it is assigned from
> '__user int *optlen'. However, it is clamped against the result of
> sizeof(), which has a type of 'size_t' ('unsigned long' for 64-bit
> platforms). This is done with min_t() because min() requires compatible
> types, which results in both len and the result of sizeof() being casted
> to 'unsigned int', meaning len changes signs and the result of sizeof()
> is truncated. From there, len is passed to copy_to_user(), which has a
> third parameter type of 'unsigned long', so it is widened and changes
> signs again. This excessive casting in combination with the KCSAN
> instrumentation causes LLVM to fail to eliminate the __bad_copy_from()
> call, failing the build.

The same issue occurs in rfcomm in functions rfcomm_sock_getsockopt and
rfcomm_sock_getsockopt_old.

Change the type of len to size_t in both rfcomm_sock_getsockopt and
rfcomm_sock_getsockopt_old and replace min_t() with min().

2c439470b2 Bluetooth: bnep: fix wild-memory-access in proto_unregister
[ Upstream commit 64a90991ba8d4e32e3173ddd83d0b24167a5668c ]

There's issue as follows:
  KASAN: maybe wild-memory-access in range [0xdead...108-0xdead...10f]
  CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: G        W
  RIP: 0010:proto_unregister+0xee/0x400
  Call Trace:
   <TASK>
   __do_sys_delete_module+0x318/0x580
   do_syscall_64+0xc1/0x1d0
   entry_SYSCALL_64_after_hwframe+0x77/0x7f

As bnep_init() ignore bnep_sock_init()'s return value, and bnep_sock_init()
will cleanup all resource. Then when remove bnep module will call
bnep_sock_cleanup() to cleanup sock's resource.
To solve above issue just return bnep_sock_init()'s return value in
bnep_exit().

4b9cf50a78 Bluetooth: Remove debugfs directory on module init failure
commit 1db4564f101b47188c1b71696bd342ef09172b22 upstream.

If bt_init() fails, the debugfs directory currently is not removed. If
the module is loaded again after that, the debugfs directory is not set
up properly due to the existing directory.

869c6ee62a Bluetooth: RFCOMM: FIX possible deadlock in rfcomm_sk_state_change
[ Upstream commit 08d1914293dae38350b8088980e59fbc699a72fe ]

rfcomm_sk_state_change attempts to use sock_lock so it must never be
called with it locked but rfcomm_sock_ioctl always attempt to lock it
causing the following trace:

90e1ff1c15 Bluetooth: MGMT: Add error handling to pair_device()
commit 538fd3921afac97158d4177139a0ad39f056dbb2 upstream.

hci_conn_params_add() never checks for a NULL value and could lead to a NULL
pointer dereference causing a crash.

Fixed by adding error handling in the function.

[ Upstream commit 932021a11805b9da4bd6abf66fe233cccd59fe0e ]

Function hci_sched_le needs to update the respective counter variable
inplace other the likes of hci_quote_sent would attempt to use the
possible outdated value of conn->{le_cnt,acl_cnt}.

960d34e61a Bluetooth: hci_core: Fix not handling link timeouts propertly
[ Upstream commit 116523c8fac05d1d26f748fee7919a4ec5df67ea ]

Change that introduced the use of __check_timeout did not account for
link types properly, it always assumes ACL_LINK is used thus causing
hdev->acl_last_tx to be used even in case of LE_LINK and then again
uses ACL_LINK with hci_link_tx_to.

To fix this __check_timeout now takes the link type as parameter and
then procedure to use the right last_tx based on the link type and pass
it to hci_link_tx_to.

ea213d57f6 Bluetooth: bnep: Fix out-of-bound access
[ Upstream commit 0f0639b4d6f649338ce29c62da3ec0787fa08cd1 ]

This fixes attempting to access past ethhdr.h_source, although it seems
intentional to copy also the contents of h_proto this triggers
out-of-bound access problems with the likes of static analyzer, so this
instead just copy ETH_ALEN and then proceed to use put_unaligned to copy
h_proto separetely.

9cfc84b1d4 Bluetooth: hci_core: cancel all works upon hci_unregister_dev()
[ Upstream commit 0d151a103775dd9645c78c97f77d6e2a5298d913 ]

syzbot is reporting that calling hci_release_dev() from hci_error_reset()
due to hci_dev_put() from hci_error_reset() can cause deadlock at
destroy_workqueue(), for hci_error_reset() is called from
hdev->req_workqueue which destroy_workqueue() needs to flush.

We need to make sure that hdev->{rx_work,cmd_work,tx_work} which are
queued into hdev->workqueue and hdev->{power_on,error_reset} which are
queued into hdev->req_workqueue are no longer running by the moment

       destroy_workqueue(hdev->workqueue);
       destroy_workqueue(hdev->req_workqueue);

are called from hci_release_dev().

Call cancel_work_sync() on these work items from hci_unregister_dev()
as soon as hdev->list is removed from hci_dev_list.

cd41a24ab4 Bluetooth: L2CAP: Fix rejecting L2CAP_CONN_PARAM_UPDATE_REQ
[ Upstream commit 806a5198c05987b748b50f3d0c0cfb3d417381a4 ]

This removes the bogus check for max > hcon->le_conn_max_interval since
the later is just the initial maximum conn interval not the maximum the
stack could support which is really 3200=4000ms.

In order to pass GAP/CONN/CPUP/BV-05-C one shall probably enter values
of the following fields in IXIT that would cause hci_check_conn_params
to fail:

TSPX_conn_update_int_min
TSPX_conn_update_int_max
TSPX_conn_update_peripheral_latency
TSPX_conn_update_supervision_timeout

6466ee65e5 Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout
[ Upstream commit adf0398cee86643b8eacde95f17d073d022f782c ]

There is a race condition between l2cap_chan_timeout() and
l2cap_chan_del(). When we use l2cap_chan_del() to delete the
channel, the chan->conn will be set to null. But the conn could
be dereferenced again in the mutex_lock() of l2cap_chan_timeout().
As a result the null pointer dereference bug will happen. The
KASAN report triggered by POC is shown below:

3212afd00e Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout
[ Upstream commit 483bc08181827fc475643272ffb69c533007e546 ]

When the sco connection is established and then, the sco socket
is releasing, timeout_work will be scheduled to judge whether
the sco disconnection is timeout. The sock will be deallocated
later, but it is dereferenced again in sco_sock_timeout. As a
result, the use-after-free bugs will happen. The root cause is
shown below:

    Cleanup Thread               |      Worker Thread
sco_sock_release                 |
  sco_sock_close                 |
    __sco_sock_close             |
      sco_sock_set_timer         |
        schedule_delayed_work    |
  sco_sock_kill                  |    (wait a time)
    sock_put(sk) //FREE          |  sco_sock_timeout
                                 |    sock_hold(sk) //USE

Fix this problem by adding a check protected by sco_conn_lock to judget
whether the conn->hcon is null. Because the conn->hcon will be set to null,
when the sock is releasing.

9c25b42905 Bluetooth: Fix type of len in {l2cap,sco}_sock_getsockopt_old()
commit 9bf4e919ccad613b3596eebf1ff37b05b6405307 upstream.

After an innocuous optimization change in LLVM main (19.0.0), x86_64
allmodconfig (which enables CONFIG_KCSAN / -fsanitize=thread) fails to
build due to the checks in check_copy_size():

  In file included from net/bluetooth/sco.c:27:
  In file included from include/linux/module.h:13:
  In file included from include/linux/stat.h:19:
  In file included from include/linux/time.h:60:

  In file included from arch/x86/include/asm/tsc.h:10:
  In file included from arch/x86/include/asm/msr.h:15:
  In file included from include/linux/percpu.h:7:
  In file included from include/linux/smp.h:118:
  include/linux/thread_info.h:244:4: error: call to '__bad_copy_from'
  declared with 'error' attribute: copy source size is too small
    244 |                         __bad_copy_from();
        |                         ^

The same exact error occurs in l2cap_sock.c. The copy_to_user()
statements that are failing come from l2cap_sock_getsockopt_old() and
sco_sock_getsockopt_old(). This does not occur with GCC with or without
KCSAN or Clang without KCSAN enabled.

len is defined as an 'int' because it is assigned from
'__user int *optlen'. However, it is clamped against the result of
sizeof(), which has a type of 'size_t' ('unsigned long' for 64-bit
platforms). This is done with min_t() because min() requires compatible
types, which results in both len and the result of sizeof() being casted
to 'unsigned int', meaning len changes signs and the result of sizeof()
is truncated. From there, len is passed to copy_to_user(), which has a
third parameter type of 'unsigned long', so it is widened and changes
signs again. This excessive casting in combination with the KCSAN
instrumentation causes LLVM to fail to eliminate the __bad_copy_from()
call, failing the build.

The official recommendation from LLVM developers is to consistently use
long types for all size variables to avoid the unnecessary casting in
the first place. Change the type of len to size_t in both
l2cap_sock_getsockopt_old() and sco_sock_getsockopt_old(). This clears
up the error while allowing min_t() to be replaced with min(), resulting
in simpler code with no casts and fewer implicit conversions. While len
is a different type than optlen now, it should result in no functional
change because the result of sizeof() will clamp all values of optlen in
the same manner as before.
