2020-01-26Bluetooth: Fix race condition in hci_release_sock()Dan Carpenter1-0/+3
Syzbot managed to trigger a use after free "KASAN: use-after-free Write in hci_sock_bind". I have reviewed the code manually and one possibly cause I have found is that we are not holding lock_sock(sk) when we do the hci_dev_put(hdev) in hci_sock_release(). My theory is that the bind and the release are racing against each other which results in this use after free.

2020-01-25Bluetooth: Move {min,max}_key_size debugfs into hci_debugfs_create_leMarcel Holtmann2-93/+61
The debugfs entries for {min,max}_key_size are created during SMP registration and thus it might lead to multiple attempts to create the same entries. Avoid this by moving them to the LE controller init section. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2020-01-25Bluetooth: Add missing checks for HCI_ISODATA_PKT packet typeMarcel Holtmann2-5/+11
The checks for HCI_ISODATA_PKT packet type are required in a few additional locations to allow sending/receiving of this new packet type. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2020-01-15Bluetooth: Implementation of MGMT_OP_SET_BLOCKED_KEYS.Alain Michaud4-8/+188
MGMT command is added to receive the list of blocked keys from user-space. The list is used to: 1) Block keys from being distributed by the device during the ke distribution phase of SMP. 2) Filter out any keys that were previously saved so they are no longer used.

2020-01-04Bluetooth: Auto tune if input MTU is set to 0Luiz Augusto von Dentz1-2/+52
This enables the code to set the input MTU using the underline link packet types when set to 0, previously this would likely be rejected by the remote peer since it would be bellow the minimal of 48 for BR/EDR or 23 for LE, that way it shall be safe to use 0 without causing any side effects. This is convenient for the likes of A2DP transport, see: https://habr.com/en/post/456182/ Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2019-10-24net: core: add generic lockdep keysTaehee Yoo1-8/+0
Some interface types could be nested. (VLAN, BONDING, TEAM, MACSEC, MACVLAN, IPVLAN, VIRT_WIFI, VXLAN, etc..) These interface types should set lockdep class because, without lockdep class key, lockdep always warn about unexisting circular locking. In the current code, these interfaces have their own lockdep class keys and these manage itself. So that there are so many duplicate code around the /driver/net and /net/. This patch adds new generic lockdep keys and some helper functions for it. This patch does below changes. a) Add lockdep class keys in struct net_device - qdisc_running, xmit, addr_list, qdisc_busylock - these keys are used as dynamic lockdep key. b) When net_device is being allocated, lockdep keys are registered. - alloc_netdev_mqs() c) When net_device is being free'd llockdep keys are unregistered. - free_netdev() d) Add generic lockdep key helper function - netdev_register_lockdep_key() - netdev_unregister_lockdep_key() - netdev_update_lockdep_key() e) Remove unnecessary generic lockdep macro and functions f) Remove unnecessary lockdep code of each interfaces. After this patch, each interface modules don't need to maintain their lockdep keys. Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

hidp_send_message was changed to return non-zero values on success, which some other bits did not expect. This caused spurious errors to be propagated through the stack, breaking some drivers, such as hid-sony for the Dualshock 4 in Bluetooth mode. As pointed out by Dan Carpenter, hid-microsoft directly relied on that assumption as well.

2019-09-05Bluetooth: mgmt: Use struct_size() helperGustavo A. R. Silva1-6/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct mgmt_rp_get_connections { ... struct mgmt_addr_info addr[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*rp) + (i * sizeof(struct mgmt_addr_info)); with: struct_size(rp, addr, i) Also, notice that, in this case, variable rp_len is not necessary, hence it is removed.

Static variable header_ops, of type header_ops, is used only once, when it is assigned to field header_ops of a variable having type net_device. This corresponding field is declared as const in the definition of net_device. Hence make header_ops constant as well to protect it from unnecessary modification. Issue found with Coccinelle.

Let hidp_send_message return the number of successfully queued bytes instead of an unconditional 0. With the return value fixed to 0, other drivers relying on hidp, such as hidraw, can not return meaningful values from their respective implementations of write(). In particular, with the current behavior, a hidraw device's write() will have different return values depending on whether the device is connected via USB or Bluetooth, which makes it harder to abstract away the transport layer.

2019-07-26bluetooth: switch to AES libraryArd Biesheuvel2-73/+33
The bluetooth code uses a bare AES cipher for the encryption operations. Given that it carries out a set_key() operation right before every encryption operation, this is clearly not a hot path, and so the use of the cipher interface (which provides the best implementation available on the system) is not really required. In fact, when using a cipher like AES-NI or AES-CE, both the set_key() and the encrypt() operations involve en/disabling preemption as well as stacking and unstacking the SIMD context, and this is most certainly not worth it for encrypting 16 bytes of data. So let's switch to the new lightweight library interface instead. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

BLE based 6LoWPAN networks are highly constrained in bandwidth. Do not take a short-cut, always check if the destination address is known to belong to a peer. As a side-effect this also removes any behavioral differences between one, and two or more connected peers.

2019-07-06Bluetooth: 6lowpan: check neighbour table for SLAACJosua Mayer1-0/+15
Like any IPv6 capable device, 6LNs can have multiple addresses assigned using SLAAC and made known through neighbour advertisements. After checking the destination address against all peers link-local addresses, consult the neighbour cache for additional known addresses. RFC7668 defines the scope of Neighbor Advertisements in Section 3.2.3: 1. "A Bluetooth LE 6LN MUST NOT register its link-local address" 2. "A Bluetooth LE 6LN MUST register its non-link-local addresses with the 6LBR by sending Neighbor Solicitation (NS) messages ..." Due to these constranits both the link-local addresses tracked in the list of 6lowpan peers, and the neighbour cache have to be used when identifying the 6lowpan peer for a destination address.
