Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to igb, ixgbe, ixgbevf, i40e and i40evf. Anjali provides a i40e/i40evf patch to add Energy Efficient Ethernet Low Power Idle stats and a fix for i40e to change the string "Side Band" to "Sideband" for consistency. Mitch provides 2 patches for i40evf to fix if the driver encounters an error while communicating with the PF driver, do not shut down the admin queue unconditionally. Add an error message when the admin queue message never completes and fix formatting on another message that was unnecessarily wrapped. Mark provides a ixgbe patch and five ixgbevf patches. Fix a possible infinite recursion when an adapter is removed and registers all read as all one's in ixgbe_clear_vmdq_generic() and ixgbe_clear_rar_generic(). Converts macros to static inline functions to align kernel coding standard and prepare for adding Live Error Recovery (LER) to ixgbevf. Change the ethtool register test to use the normal register accessor functions and eliminate macors used for calling register test functions to make error exits more clear. Checks all register reads for adapter removal by checking the status register after any register read that returns all F's since the status register will never return 0xFFFFFFFF unless the adapter is removed. Jacob implements SIOCGHWTSTAMP ioctl for igb which enables user processes to read the current hardware stamp config settings non-destructively. Todd adds the initial register read and write for surprise removal (LER) for igb. Christian Engelmayer fixes an igb memory leak in the igb_get_module_eeprom() error handling path. Ken Ichikawa provides a fix for igb, specifically for 82575 hardware to specify -1 to the phc_index for ethtool's get_ts_info, otherwise a wrong value will be set to the phc_index. Christopher Paasch fixes a null pointer dereference in igb and makes sure to unset the HAS_MSIX flag when the driver falls back to MSI only. ==================== Signed-off-by:David S.

The P1010 device tree restricts the number of supported interrupt groups to 1, although the eth controller can support 2 interrupt groups and the driver assumes the Multi-Group mode ("fsl,etsec2" model). So, in this case the assumption that the Multi-Group mode (MQ_MG_MODE) devices always support 2 interrupt groups is false. To fix this, a check for the actual number of interrupt groups enabled in the board's device tree has been added in gfar_probe for the "fsl,etsec2" devices. Without this fix, P1010 based boards claim support for 2 Tx queues to the net stack but only one is actually allocated, leading to NULL access in xmit. This issue was introduced by enabling Single-Queue polling for the P1010 devices.

When changing one 16bit value by another in IP header, we can adjust the IP checksum by doing a simple operation described in RFC 1624, as reminded by David. csum_partial() is a complex function on x86_64, not really suited for small number of checksummed bytes. I spotted csum_partial() being in the top 20 most consuming functions (more than 1 %) in a GRO workload, which was rather unexpected. The caller was inet_gro_complete() doing a csum_replace2() when building the new IP header for the GRO packet. Signed-off-by:

Antonio Quartulli says: ==================== Included changes: - use ether_addr_copy instead of memcpy when possible - implement new multicast packet optimisation - improve several kerneldoc sections - minor code cleanups here you have our patchset for net-next/linux-3.15. They are 16 patches but most of them are just small cleanups and kerneldoc improvements. The only big change is the one from patch 8 to 13 by Linus Lüssing that introduces a new multicast packets optimisation. This new component aims to reduce the air overhead by sending multicast packets as bat-unicast when only one destination exists or by dropping them directly at the source if the multicast group is totally empty. In patch 11 Linus introduces an atomic_t variable, that like others that we already have is only object of write and read, thus making the atomic characteristic totally useless. Unfortunately this is part of our sysfs framework, that helps the developer to introduce new knobs by using few macros only. For this reason we decided to keep Linus' new knob for now, but I'd like to let you know that we are in the process of re-working such framework in order to convert all the current (useless) atomic_t to boolean in one go. ==================== Signed-off-by: -

With this patch a node sends IPv4 multicast packets to nodes which have a BATADV_MCAST_WANT_ALL_IPV4 flag set and IPv6 multicast packets to nodes which have a BATADV_MCAST_WANT_ALL_IPV6 flag set, too. Why is this needed? There are scenarios involving bridges where multicast report snooping and multicast TT announcements are not sufficient, which would lead to packet loss for some nodes otherwise: MLDv1 and IGMPv1/IGMPv2 have a suppression mechanism for multicast listener reports. When we have an MLDv1/IGMPv1/IGMPv2 querier behind a bridge then our snooping bridge is potentially not going to see any reports even though listeners exist because according to RFC4541 such reports are only forwarded to multicast routers: ----------------------------------------------------------- --------------- {Querier}---|Snoop. Switch|----{Listener} --------------- \ ^ ------- | br0 | < ??? ------- \ _-~---~_ _-~/ ~-_ ~ batman-adv \-----{Sender} \~_ cloud ~/ -~~__-__-~_/ I) MLDv1 Query: {Querier} -> flooded II) MLDv1 Report: {Listener} -> {Querier} -> br0 cannot detect the {Listener} => Packets from {Sender} need to be forwarded to all detected listeners and MLDv1/IGMPv1/IGMPv2 queriers. ----------------------------------------------------------- Note that we do not need to explicitly forward to MLDv2/IGMPv3 queriers, because these protocols have no report suppression: A bridge has no trouble detecting MLDv2/IGMPv3 listeners. Even though we do not support bridges yet we need to provide the according infrastructure already to not break compatibility later. Signed-off-by:Linus Lüssing <linus.luessing@web.de> Signed-off-by:

With this patch a node may additionally perform the dropping or unicasting behaviour for a link-local IPv4 and link-local-all-nodes IPv6 multicast packet, too. The extra counter and BATADV_MCAST_WANT_ALL_UNSNOOPABLES flag is needed because with a future bridge snooping support integration a node with a bridge on top of its soft interface is not able to reliably detect its multicast listeners for IPv4 link-local and the IPv6 link-local-all-nodes addresses anymore (see RFC4541, section 2.1.2.2 and section 3). Even though this new flag does make "no difference" now, it'll ensure a seamless integration of multicast bridge support without needing to break compatibility later. Also note, that even with multicast bridge support it won't be possible to optimize 224.0.0.x and ff02::1 towards nodes with bridges, they will always receive these ranges. Signed-off-by:

With this patch a multicast packet is not always simply flooded anymore, the behaviour for the following cases is changed to reduce unnecessary overhead: If all nodes within the horizon of a certain node have signalized multicast listener announcement capability then an IPv6 multicast packet with a destination of IPv6 link-local scope (excluding ff02::1) coming from the upstream of this node... * ...is dropped if there is no according multicast listener in the translation table, * ...is forwarded via unicast if there is a single node with interested multicast listeners * ...and otherwise still gets flooded.

Richard Cochran says: ==================== ptp: dynamic pin control This patch series introduces a way of changing the auxiliary PTP Hardware Clock functions (periodic output signals and time stamping external signals) at run time. In the past on the netdev list, we have discussed other ways to handle this, such as module parameters and ethtool. This series implements a new PHC ioctl because that is the most natural way. Users already activate the auxiliary functions via the ioctls. The sysfs interface has also been expanded so that the pin configuration can be programmed using shell scripts. The first patch adds the new ioctls. The PHC subsystem does most of the work of maintaining the function-to-pin mapping. Drivers will only need to allocate and initialize a pin configuration table and also provide a new method that validates a particular assignment. Patches 5 and 6 just clean up a couple of issues in the phyter driver, and the remaining patches actually hook the phyter's pins into the new system. * ChangeLog ** V3 - simplify locking in the set pin logic ** V2 - fix bug in sysfs code on init error path - rename ptp_setpin() to ptp_set_pinfunc() - rename .setpin() to .verify() in the driver interface - simplify ptp_find_pin() logic - use correct test when checking whether the pin with the calibration function is being reprogrammed ==================== Signed-off-by: -
