Input packet processing for local sockets involves two major demuxes. One for the route and one for the socket. But we can optimize this down to one demux for certain kinds of local sockets. Currently we only do this for established TCP sockets, but it could at least in theory be expanded to other kinds of connections. If a TCP socket is established then it's identity is fully specified. This means that whatever input route was used during the three-way handshake must work equally well for the rest of the connection since the keys will not change. Once we move to established state, we cache the receive packet's input route to use later. Like the existing cached route in sk->sk_dst_cache used for output packets, we have to check for route invalidations using dst->obsolete and dst->ops->check(). Early demux occurs outside of a socket locked section, so when a route invalidation occurs we defer the fixup of sk->sk_rx_dst until we are actually inside of established state packet processing and thus have the socket locked.

Don't pretend that inet_protos[] and inet6_protos[] are hashes, thay are just a straight arrays. Remove all unnecessary hash masking. Document MAX_INET_PROTOS. Use RAW_HTABLE_SIZE when appropriate. Reported-by:

Always bind to control interface regardless of whether it is a shared interface or not. A QMI/wwan function is required to provide both a control interface (QMI) and a data interface (wwan). All devices supported by this driver do so. But the vendors may choose to use different USB descriptor layouts, and some vendors even allow the same device to present different layouts. Most of these devices use a USB descriptor layout with a single USB interface for both control and data. But some split control and data into two interfaces, bound together by a CDC Union descriptor on the control interface. Before the cdc-wdm subdriver support was added, this split was used to let cdc-wdm drive the QMI control interface and qmi_wwan drive the wwna data interface. This split driver model has a number of issues: - qmi_wwan must match on the data interface descriptor, which often are indistiguishable from data interfaces belonging to other CDC (like) functions like ACM - supporting a single QMI/wwan function requires adding the device to two drivers - syncronizing the probes among a number of drivers, to ensure selecting the correct driver, is difficult unless all drivers match on the same interface This patch resolves these problems by using the same probing mechanism as cdc-ether for devices with a two- interface USB descriptor layout. This makes the driver behave consistently, supporting both the control and data part of the QMI/wwan function, regardless of the USB descriptors.

Most of the subdriver registration code can be reused for devices with separate control and data interfaces. Move the code a bit around to prepare for such reuse. Signed-off-by:

usbnet allocates a fixed size array for minidriver specific state. Naming the fields and taking advantage of type checking is a bit more failsafe than casting array elements each time they are referenced. Signed-off-by:

currently, when port is created and per-port options are present, there options are sent to userspace with ifindex of port which userspace does not know about. Port add message goes right after. This patch corrects message ordering so userspace would not be confused. Signed-off-by:

Marc Kleine-Budde says: ==================== here is our second pull request for net-next. In this series Federico Vaga adds a pci driver for c_can/d_can hardware using the existing generic c_can driver. The remaining 6 patches are by Oliver Hartkopp. He adds CANFD support to the CAN stack while keeping binary compatibility for existing applications. CANFD is an extension to the existing CAN standard, it allows longer CAN frames and/or higher data rates. There's no real hardware available yet, but this series adds CANFD support to the vcan driver. ==================== Signed-off-by: -

John Linville says: ==================== This is a sizeable batch of updates intended for 3.6... The bulk of the changes here are Bluetooth. Gustavo says: Here goes the first Bluetooth pull request for 3.6, we have queued quite a lot of work. Andrei Emeltchenko added the AMP Manager code, a lot of work is needed, but the first bit are already there. This code is disabled by default. Mat Martineau changed the whole L2CAP ERTM state machine code, replacing the old one with a new implementation. Besides that we had lot of coding style fixes (to follow net rules), more l2cap core separation from socket and many clean ups and fixed all over the tree. Along with the above, there is a healthy dose of ath9k, iwlwifi, and other driver updates. There is also another pull from the wireless tree to resolve some merge issues. I also fixed-up some merge discrepencies between net-next and wireless-next. ==================== Signed-off-by: -

Currently the CNIC-related L2 CIDs (for sending control FCoE / iSCSI packets) were at fixed position, according to the maximal number of RSS queues multiplied by the number of traffic-classes. This change makes the CIDs dynamic, as they are defined to be right after the highest RSS CID. This decreases the memory allocated for the context. Signed-off-by:

In the current scheme the transmission queues of traffic-class 0 were 0-15, the transmission queues of traffic-class 1 were 16-31 and so on. If the number of RSS queues was smaller than 16, there were gaps in transmission queues numbering, as well as in CIDs numbering. This is both a waste (especially when 16 is increased to 64), and may causes problems with flushing queues when reducing the number of RSS queues (using ethtool -L). The new scheme eliminates the gaps. Signed-off-by:

With increased number of RSS queues, each multiplied by the number of traffic- classes, we may have up to 64*3=192 CIDs. The current driver scheme with regard to context allocation supports only 64 CIDs. The new scheme enables scatter- gatehr list of pages for the context. Signed-off-by:

1. In multi-function device, show only the online tests in self-test results as only these test are performed (offline tests cannot be performed as they may corrupt the traffic of other functions on the same physical port). Note that multi-function mode cannot change while the driver is up. 2. Check result code in NIC load and act accordingly. Signed-off-by:
