Link failover and synchronization have until now been handled by the links themselves, forcing them to have knowledge about and to access parallel links in order to make the two algorithms work correctly. In this commit, we move the control part of this functionality to the link aggregation level in node.c, which is the right location for this. As a result, the two algorithms become easier to follow, and the link implementation becomes simpler. Tested-by:

In the next commit, we will move link synch/failover orchestration to the link aggregation level. In order to do this, we first need to extend the node FSM with two more states, NODE_SYNCHING and NODE_FAILINGOVER, plus four new events to enter and leave those states. This commit introduces this change, without yet making use of it. The node FSM now looks as follows: +-----------------------------------------+ | PEER_DOWN_EVT| | | +------------------------+----------------+ | |SELF_DOWN_EVT | | | | | | | | +-----------+ +-----------+ | | |NODE_ | |NODE_ | | | +----------|FAILINGOVER|<---------|SYNCHING |------------+ | | |SELF_ +-----------+ FAILOVER_+-----------+ PEER_ | | | |DOWN_EVT | A BEGIN_EVT A | DOWN_EVT| | | | | | | | | | | | | | | | | | | | |FAILOVER_|FAILOVER_ |SYNCH_ |SYNCH_ | | | | |END_EVT |BEGIN_EVT |BEGIN_EVT|END_EVT | | | | | | | | | | | | | | | | | | | | | +--------------+ | | | | | +------->| SELF_UP_ |<-------+ | | | | +----------------| PEER_UP |------------------+ | | | | |SELF_DOWN_EVT +--------------+ PEER_DOWN_EVT| | | | | | A A | | | | | | | | | | | | | | PEER_UP_EVT| |SELF_UP_EVT | | | | | | | | | | | V V V | | V V V +------------+ +-----------+ +-----------+ +------------+ |SELF_DOWN_ | |SELF_UP_ | |PEER_UP_ | |PEER_DOWN | |PEER_LEAVING|<------|PEER_COMING| |SELF_COMING|------>|SELF_LEAVING| +------------+ SELF_ +-----------+ +-----------+ PEER_ +------------+ | DOWN_EVT A A DOWN_EVT | | | | | | | | | | SELF_UP_EVT| |PEER_UP_EVT | | | | | | | | | |PEER_DOWN_EVT +--------------+ SELF_DOWN_EVT| +------------------->| SELF_DOWN_ |<--------------------+ | PEER_DOWN | +--------------+ Tested-by:

In many cases the call order when a link is reset goes as follows: tipc_node_xx()->tipc_link_reset()->tipc_node_link_down() This is not the right order if we want the node to be in control, so in this commit we change the order to: tipc_node_xx()->tipc_node_link_down()->tipc_link_reset() The fact that tipc_link_reset() now is called from only one location with a well-defined state will also facilitate later simplifications of tipc_link_reset() and the link FSM.

In line with our effort to let the node level have full control over its links, we want to move all link reset calls from link.c to node.c. Some of the calls can be moved by simply moving the calling function, when this is the right thing to do. For the remaining calls we use the now established technique of returning a TIPC_LINK_DOWN_EVT flag from tipc_link_rcv(), whereafter we perform the reset call when the call returns. This change serves as a preparation for the coming commits. Tested-by:

The function tipc_link_activate() is redundant, since it mostly performs settings that have already been done in a preceding tipc_link_reset(). There are three exceptions to this: - The actual state change to TIPC_LINK_WORKING. This should anyway be done in the FSM, and not in a separate function. - Registration of the link with the bearer. This should be done by the node, since we don't want the link to have any knowledge about its specific bearer. - Call to tipc_node_link_up() for user access registration. With the new role distribution between link aggregation and link level this becomes the wrong call order; tipc_node_link_up() should instead be called directly as a result of a TIPC_LINK_UP event, hence by the node itself. This commit implements those changes. Tested-by:

Commit 6fd99094 ("ipv6: Don't reduce hop limit for an interface") disabled accept hop limit from RA if it is smaller than the current hop limit for security stuff. But this behavior kind of break the RFC definition. RFC 4861, 6.3.4. Processing Received Router Advertisements A Router Advertisement field (e.g., Cur Hop Limit, Reachable Time, and Retrans Timer) may contain a value denoting that it is unspecified. In such cases, the parameter should be ignored and the host should continue using whatever value it is already using. If the received Cur Hop Limit value is non-zero, the host SHOULD set its CurHopLimit variable to the received value. So add sysctl option accept_ra_min_hop_limit to let user choose the minimum hop limit value they can accept from RA. And set default to 1 to meet RFC standards. Signed-off-by:

During recent discussions we had with Michael, we found that it would be useful to have an indicator that tells the JIT that an eBPF program had been migrated from classic instructions into eBPF instructions, as only in that case A and X need to be cleared in the prologue. Such eBPF programs do not set a particular type, but all have BPF_PROG_TYPE_UNSPEC. Thus, introduce a small helper for cde66c2d ("s390/bpf: Only clear A and X for converted BPF programs") and possibly others in future. Signed-off-by:

As JITs start to perform optimizations whether to clear A and X on eBPF programs in the prologue, we should actually assign a program type to the native eBPF test cases. It doesn't really matter which program type, as these instructions don't go through the verifier, but it needs to be a type != BPF_PROG_TYPE_UNSPEC. This reflects eBPF programs loaded via bpf(2) system call (!= type unspec) vs. classic BPF to eBPF migrations (== type unspec). Signed-off-by:

This patch fix a possible race after calling register_netdev. After calling netdev_register it could be possible that netdev_ops callbacks use the uninitialized private data of lowpan_dev. By moving the initialization of this data before netdev_register we can be sure that initialized private data is be used after netdev_register. Signed-off-by:

When transmitting a packet via a mac802154 driver that can sleep in its transmit function, mac802154 defers the call to the driver's transmit function to a per-device workqueue. However, mac802154 uses a single global work_struct for this, which means that if you have more than one registered mac802154 interface in the system, and you transmit on more than one of them at the same time, you'll very easily cause memory corruption. This patch moves the deferred transmit processing state from global variables to struct ieee802154_local, and this seems to fix the memory corruption issue. Signed-off-by:

btusb currently has a generic match on USB device descriptors: { USB_DEVICE_INFO(0xe0, 0x01, 0x01) }, However, http://www.usb.org/developers/defined_class states: Base Class E0h (Wireless Controller) This base class is defined for devices that are Wireless controllers. Values not shown in the table below are reserved. These class codes are to be used in Interface Descriptors, with the exception of the Bluetooth class code which can also be used in a Device Descriptor. Add a match on the interface descriptors accordingly. This fixes compatibility with the RTL8723AU device shown below. This device conforms to the USB Interface Association Descriptor specification, which requires the device to have class ef/02/01. The extra IAD descriptor then specifies that interfaces 0 and 1 belong to the same function/driver, which is true. Provided that the Bluetooth device class spec accepts use of the IAD, I imagine that technically, all btusb devices should be configured like this.

Ethernet Management Datagrams (EMADs) are Ethernet packets sent between the host and the device in order to configure the available device registers. Another use case is notifications sent from the device to the host, letting it know about certain events, such as port up / down. Add the ability to construct EMADs with provisions to construct and parse the registers' payloads. Implement EMAD transaction layer which is responsible for the reliable transmission of EMADs. Also, add an infrastructure used by the switch driver to register for particular events generated by the device. Signed-off-by:

It was used to update netdev priv parameters that require stopping and re-opening the device in a generic way - it got the new parameters and did: ndo_stop(), copy new parameters into current parameters, ndo_open(). We chose to remove it for two reasons: 1) It requires additional instance of struct mlx5e_params on the stack and looking forward we expect this struct to grow. 2) Sometimes we want to do additional operations (besides just updating the priv parameters) while the netdev is stopped. For example, updating netdev->mtu @mlx5e_change_mtu() should be done while the netdev is stopped (done in this commit). Signed-off-by:
