* ipv6: enable IPV6_FLOWLABEL_MGR for getsockoptFlorent Fourcot2013-11-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | It is already possible to set/put/renew a label with IPV6_FLOWLABEL_MGR and setsockopt. This patch add the possibility to get information about this label (current value, time before expiration, etc). It helps application to take decision for a renew or a release of the label. v2: * Add spin_lock to prevent race condition * return -ENOENT if no result found * check if flr_action is GET v3: * move the spin_lock to protect only the relevant code Signed-off-by: Florent Fourcot <florent.fourcot@enst-bretagne.fr> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.

| | * Bluetooth: Remove sk member from struct l2cap_chanGustavo Padovan2013-10-211-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | There is no access to chan->sk in L2CAP core now. This change marks the end of the task of splitting L2CAP between Core and Socket, thus sk is now gone from struct l2cap_chan.

| | * Bluetooth: Add support for setting DUT modeMarcel Holtmann2013-10-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Device Under Test (DUT) mode is useful for doing certification testing and so expose this as debugfs option. This mode is actually special since you can only enter it. Restoring normal operation means that a HCI Reset is required. The current mode value gets tracked as a new device flag and when disabling it, the correct command to reset the controller is sent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling and disabling SSP debug mode is useful for development. This adds a debugfs entry that allows to configure the SSP debug mode. On purpose this has been implemented as debugfs entry and not a public API since it is really only useful during testing and development.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device blacklist is not taking care of the address type. Actually store the address type in the list entries and also use them when looking up addresses in the table. This is actually a serious bug. When adding a LE public address to the blacklist, then it would be blocking a device on BR/EDR. And this is not the expected behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of creating an new function pointer to report errors we are just reusing state_change for that and there is a simple reason for this, one place in the l2cap_core.c code needs, in a locked sk, set both the sk_state and sk_err. If we create two different functions for this we would need to release the lock between the two operation putting the socket in non desired state. The change is transparent to the l2cap_core.c code, user that only needs to set the state won't need any modification. This is another step of an ongoing work to make l2cap_core.c totally independent from l2cap's struct sock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the discoverable timeout triggers and limited discoverable mode was used, then the class of device needs to be updated to remove the limited discoverable bit. To keep the class of device logic in a central place, expose a new function mgmt_discoverable_timeout that can be called from the timeout callback. In case the class of device value needs updating, it will add the HCI command to the transaction.

DFS channels may only be used if this attribute is supplied and the driver supports it. Driver support will be checked even if a channel without DFS will be initially joined, as a DFS channel may be chosen later.
