2014-05-20Bluetooth: Remove unnecessary work structs from SMP codeJohan Hedberg
When the SMP code was initially created (mid-2011) parts of the Bluetooth subsystem were still not converted to use workqueues. This meant that the crypto calls, which could sleep, couldn't be called directly. Because of this the "confirm" and "random" work structs were introduced. These days the entire Bluetooth subsystem runs through workqueues which makes these structs unnecessary. This patch removes them and converts the calls to queue them to use direct function calls instead.

2014-05-20Bluetooth: Make SMP context private to smp.cJohan Hedberg
There are no users of the smp_chan struct outside of smp.c so move it away from smp.h. The addition of the l2cap.h include to hci_core.c, hci_conn.c and mgmt.c is something that should have been there already previously to avoid warnings of undeclared struct l2cap_conn, but the compiler warning was apparently shadowed away by the mention of l2cap_conn in the struct smp_chan definition.

2014-04-25Bluetooth: Fix redundant encryption request for reauthenticationJohan Hedberg
When we're performing reauthentication (in order to elevate the security level from an unauthenticated key to an authenticated one) we do not need to issue any encryption command once authentication completes. Since the trigger for the encryption HCI command is the ENCRYPT_PEND flag this flag should not be set in this scenario. Instead, the REAUTH_PEND flag takes care of all necessary steps for reauthentication.

Commit 1c2e004183178 introduced an event handler for the encryption key refresh complete event with the intent of fixing some LE/SMP cases. However, this event is shared with BR/EDR and there we actually want to act only on the auth_complete event (which comes after the key refresh). If we do not do this we may trigger an L2CAP Connect Request too early and cause the remote side to return a security block error.

2014-04-11net: Fix use after free by removing length arg from sk_data_ready callbacks.David S. Miller
Several spots in the kernel perform a sequence like: skb_queue_tail(&sk->s_receive_queue, skb); sk->sk_data_ready(sk, skb->len); But at the moment we place the SKB onto the socket receive queue it can be consumed and freed up. So this skb->len access is potentially to freed up memory. Furthermore, the skb->len can be modified by the consumer so it is possible that the value isn't accurate. And finally, no actual implementation of this callback actually uses the length argument. And since nobody actually cared about it's value, lots of call sites pass arbitrary values in such as '0' and even '1'. So just remove the length argument from the callback, that way there is no confusion whatsoever and all of these use-after-free cases get fixed as a side effect. Based upon a patch by Eric Dumazet and his suggestion to audit this issue tree-wide. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-04-11Bluetooth: Request MITM Protection when initiatorMikel Astiz
The GAP Specification gives the flexibility to decide whether MITM Protection is requested or not (Bluetooth Core Specification v4.0 Volume 3, part C, section 6.5.3) when replying to an HCI_EV_IO_CAPA_REQUEST event. The recommendation is *not* to set this flag "unless the security policy of an available local service requires MITM Protection" (regardless of the bonding type). However, the kernel doesn't necessarily have this information and therefore the safest choice is to always use MITM Protection, also for General Bonding. This patch changes the behavior for the General Bonding initiator role, always requesting MITM Protection even if no high security level is used. Depending on the remote capabilities, the protection might not be actually used, and we will accept this locally unless of course a high security level was originally required. Note that this was already done for Dedicated Bonding. No-Bonding is left unmodified because MITM Protection is normally not desired in these cases.

2014-04-11Bluetooth: Use MITM Protection when IO caps allow itTimo Mueller
When responding to a remotely-initiated pairing procedure, a MITM protected SSP associaton model can be used for pairing if both local and remote IO capabilities are set to something other than NoInputNoOutput, regardless of the bonding type (Dedicated or General). This was already done for Dedicated Bonding but this patch proposes to use the same policy for General Bonding as well. The GAP Specification gives the flexibility to decide whether MITM Protection is used ot not (Bluetooth Core Specification v4.0 Volume 3, part C, section 6.5.3). Note however that the recommendation is *not* to set this flag "unless the security policy of an available local service requires MITM Protection" (for both Dedicated and General Bonding). However, as we are already requiring MITM for Dedicated Bonding, we will follow this behaviour also for General Bonding.

2014-03-29Bluetooth: Fix address in unmergeable device found eventsJohan Hedberg
When sending out a device found event caused by an advertising report in the situation where we couldn't store the report as a pending one, the code was incorrectly trying to use the address and address type from the pending data. Since the pending data is cleared in the previous line this causes a potentially incorrect address type and an address of BDADDR_ANY.

2014-03-26Bluetooth: Merge ADV_IND/ADV_SCAN_IND and SCAN_RSP togetherJohan Hedberg
To avoid too many events being sent to user space and to help parsing of all available remote device data it makes sense for us to wait for the scan response and send a single merged Device Found event to user space. This patch adds a few new variables to hci_dev to track the last received ADV_IND/ADV_SCAN_IND, i.e. those which will cause a SCAN_REQ to be send in the case of active scanning. When the SCAN_RSP is received the pending data is passed together with the SCAN_RSP to the mgmt_device_found function which takes care of merging them into a single Device Found event. We also need a bit of extra logic to handle situations where we don't receive a SCAN_RSP after caching some data. In such a scenario we simply have to send out the pending data as it is and then operate on the new report as if there was no pending data. We also need to send out any pending data when scanning stops as well as ensure that the storage is empty at the start of a new active scanning session. These both cases are covered by the update to the hci_cc_le_set_scan_enable function in this patch.
