Add a timeout to prevent the do while loop running in an infinite loop. This ensures that the channel will be instructed to close within 10 seconds so prevents l2cap_sock_shutdown() getting stuck forever. Returns -ENOLINK when the timeout is reached. The channel will be subequently closed and not all data will be ACK'ed. Signed-off-by: NDean Jenkins <Dean_Jenkins@mentor.com> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

Use chan->state instead of chan->conn because waiting for ACK's is only possible in the BT_CONNECTED state. Also avoids reference to the conn structure so makes locking easier. Only call __l2cap_wait_ack() when the needed condition of chan->unacked_frames > 0 && chan->state == BT_CONNECTED is true and convert the while loop to a do while loop. __l2cap_wait_ack() change the function prototype to pass in the chan variable as chan is already available in the calling function l2cap_sock_shutdown().

During execution of l2cap_sock_shutdown() which might sleep, the sk and chan structures can be in an unlocked condition which potentially allows the structures to be freed by other running threads. Therefore, there is a possibility of a malfunction or memory reuse after being freed. Keep the sk and chan structures alive during the execution of l2cap_sock_shutdown() by using their respective hold and put functions. This allows the structures to be freeable at the end of l2cap_sock_shutdown().

This patch introduces suspend and resume callbacks to mac802154. When doing suspend we calling the stop driver callback which should stop the receiving of frames. A transceiver should go into low-power mode then. Calling resume will call the start driver callback, which starts receiving again and allow to transmit frames. This was tested only with the fakelb driver and a qemu vm by doing the following commands: echo "devices" > /sys/power/pm_test echo "freeze" > /sys/power/state while doing some high traffic between two fakelb phys.

The iphc module depends on CONFIG_IPV6, because it's not very useful to build the module without IPv6 support. Recently an user reported about issues for setting an IPv6 address to a 6LoWPAN interface. The issues was solved by modprobe the ipv6 module before. To avoid such user issues we try to request the ipv6 module when the 6LoWPAN module is loaded.

Some architectures like POWER can have a NUMA node_possible_map that contains sparse entries. This causes memory corruption with openvswitch since it allocates flow_cache with a multiple of num_possible_nodes() and assumes the node variable returned by for_each_node will index into flow->stats[node]. Use nr_node_ids to allocate a maximal sparse array instead of num_possible_nodes(). The crash was noticed after 3af229f2 was applied as it changed the node_possible_map to match node_online_map on boot.

In commit d999297c ("tipc: reduce locking scope during packet reception") we introduced a new function tipc_link_proto_rcv(). This function contains a bug, so that it sometimes by error sends out a non-zero link priority value in created protocol messages. The bug may lead to an extra link reset at initial link establising with older nodes. This will never happen more than once, whereafter the link will work as intended. We fix this bug in this commit.

Introduces a new dst_metadata which enables to carry per packet metadata between forwarding and processing elements via the skb->dst pointer. The structure is set up to be a union. Thus, each separate type of metadata requires its own dst instance. If demand arises to carry multiple types of metadata concurrently, metadata dst entries can be made stackable. The metadata dst entry is refcnt'ed as expected for now but a non reference counted use is possible if the reference is forced before queueing the skb. In order to allow allocating dsts with variable length, the existing dst_alloc() is split into a dst_alloc() and dst_init() function. The existing dst_init() function to initialize the subsystem is being renamed to dst_subsys_init() to make it clear what is what. The check before ip_route_input() is changed to ignore metadata dsts and drop the dst inside the routing function thus allowing to interpret metadata in a later commit.
