2014-03-22batman-adv: Announce new capability via multicast TVLVLinus Lüssing
If the soft interface of a node is not part of a bridge then a node announces a new multicast TVLV: The existence of this TVLV signalizes that this node is announcing all of its multicast listeners via the translation table infrastructure.

2014-03-20Bluetooth: Fix address value for early disconnection eventsJohan Hedberg
We need to ensure that we do not send events to user space with the identity address if we have not yet notified user space of the IRK. The code was previously trying to handle this for the mgmt_pair_device response (which worked well enough) but this is not the only connection related event that might be sent to user space before pairing is successful: another important event is Device Disconnected. The issue can actually be solved more simply than the solution previously used for mgmt_pair_device. Since we do have the identity address tracked as part of the remote IRK struct we can just copy it over from there to the hci_conn struct once we've for real sent the mgmt event for the new IRK.

2014-03-19Bluetooth: Fix Pair Device response parameters for pairing failureJohan Hedberg
It is possible that pairing fails after we've already received remote identity information. One example of such a situation is when re-encryption using the LTK fails. In this case the hci_conn object has already been updated with the identity address but user space does not yet know about it (since we didn't notify it of the new IRK yet). To ensure user space doesn't get a Pair Device command response with an unknown address always use the same address in the response as was used for the original command.

2014-03-19Bluetooth: Fix SMP user passkey notification mgmt eventJohan Hedberg
When performing SMP pairing with MITM protection one side needs to enter the passkey while the other side displays to the user what needs to be entered. Nowhere in the SMP specification does it say that the displaying side needs to any kind of confirmation of the passkey, even though a code comment in smp.c implies this. This patch removes the misleading comment and converts the code to use the passkey notification mgmt event instead of the passkey confirmation mgmt event.

2014-03-19cfg80211/mac80211: ignore signal if the frame was heard on wrong channelEmmanuel Grumbach
On 2.4Ghz band, the channels overlap since the delta between different channels is 5Mhz while the width of the receiver is 20Mhz (at least). This means that we can hear beacons or probe responses from adjacent channels. These frames will have a significant lower RSSI which will feed all kinds of logic with inaccurate data. An obvious example is the roaming algorithm that will think our AP is getting weak and will try to move to another AP. In order to avoid this, update the signal only if the frame has been heard on the same channel as the one advertised by the AP in its DS / HT IEs. We refrain from updating the values only if the AP is already in the BSS list so that we will still have a valid (but inaccurate) value if the AP was heard on an adjacent channel only. To achieve this, stop taking the channel from DS / HT IEs in mac80211. The DS / HT IEs is taken into account to discard the frame if it was received on a disabled channel. This can happen due to the same phenomenon: the frame is sent on channel 12, but heard on channel 11 while channel 12 can be disabled on certain devices. Since this check is done in cfg80211, stop even checking this in mac80211.

Since Stanislaw's patch removing the quiescing code, mac80211 had a race regarding suspend vs. authentication: as cfg80211 doesn't track authentication attempts, it can't abort them.

git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next Steffen Klassert says: ==================== One patch to rename a newly introduced struct. The rest is the rework of the IPsec virtual tunnel interface for ipv6 to support inter address family tunneling and namespace crossing. 1) Rename the newly introduced struct xfrm_filter to avoid a conflict with iproute2. From Nicolas Dichtel. 2) Introduce xfrm_input_afinfo to access the address family dependent tunnel callback functions properly. 3) Add and use a IPsec protocol multiplexer for ipv6. 4) Remove dst_entry caching. vti can lookup multiple different dst entries, dependent of the configured xfrm states. Therefore it does not make to cache a dst_entry. 5) Remove caching of flow informations. vti6 does not use the the tunnel endpoint addresses to do route and xfrm lookups. 6) Update the vti6 to use its own receive hook. 7) Remove the now unused xfrm_tunnel_notifier. This was used from vti and is replaced by the IPsec protocol multiplexer hooks. 8) Support inter address family tunneling for vti6. 9) Check if the tunnel endpoints of the xfrm state and the vti interface are matching and return an error otherwise. 10) Enable namespace crossing for vti devices. ==================== Signed-off-by: David S.

2014-03-18Bluetooth: Fix MITM flag when initiating SMP pairingJohan Hedberg
The pairing process initiated through mgmt sets the conn->auth_type value regardless of BR/EDR or LE pairing. This value will contain the MITM flag if the local IO capability allows it. When sending the SMP pairing request we should check the value and ensure that the MITM bit gets correctly set in the bonding flags.

2014-03-18Bluetooth: Fix smp_e byte order to be consistent with SMP specificationJohan Hedberg
The SMP specification is written with the assumption that both key information, plaintextData and encryptedData follow the same little endian byte ordering as the rest of SMP. Since the kernel crypto routines expect big endian data the code has had to do various byte swapping tricks to make the behavior as expected, however the swapping has been scattered all around the place. This patch centralizes the byte order swapping into the smp_e function by making its public interface match what the other SMP functions expect as per specification. The benefit is vastly simplified calls to smp_e. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

To make it possible to (correctly) pass data declared as const as the src parameter to the swap56 and swap128 functions declare this parameter also as const. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Fix from Nikolay Aleksandrov. 2) security_xfrm_policy_alloc() can be called in process and atomic context. Add an argument to let the callers choose the appropriate way.
