| * net: fec: add netif status check before set mac addressNimrod Andy2015-09-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exist one issue by below case that case system hang: ifconfig eth0 down ifconfig eth0 hw ether 00:10:19:19:81:19 After eth0 down, all fec clocks are gated off. In the .fec_set_mac_address() function, it will set new MAC address to registers, which causes system hang. So it needs to add netif status check to avoid registers access when clocks are gated off. Until eth0 up the new MAC address are wrote into related registers. V2: As Lucas Stach's suggestion, add a comment in the code to explain why it needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current check of phydev with IS_ERR(phydev) may make not much sense because of_phy_connect() returns NULL on failure instead of error value. Still for checking result of phy_connect() IS_ERR() makes perfect sense. So let's use combined check IS_ERR_OR_NULL() that covers both cases.

| * net: fec: normalize return value of pm_runtime_get_sync() in MDIO writeMaciej S. Szmigiero2015-09-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If fec MDIO write method succeeds its return value comes from call to pm_runtime_get_sync(). But pm_runtime_get_sync() can also return 1. In case of Micrel KSZ9031 PHY this value will then be returned along the call chain of phy_write() -> ksz9031_extended_write() -> ksz9031_center_flp_timing() -> ksz9031_config_init() -> phy_init_hw() -> phy_attach_direct() -> phy_connect_direct(). Then phy_connect() will cast it into a pointer using ERR_PTR(), which then fec_enet_mii_probe() will try to dereference resulting in an oops. Fix it by normalizing return value of pm_runtime_get_sync() to be zero if positive in MDIO write method.

| * be2net: Revert "make the RX_FILTER command asynchronous" commitSathya Perla2015-09-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The be_cmd_rx_filter() routine sends a non-embedded cmd to the FW and used a pre-allocated dma memory to hold the cmd payload. This worked fine when this cmd was synchronous. This cmd was changed to asynchronous mode by the commit 8af65c2f4("make the RX_FILTER command asynchronous"). So now when there are two quick invocations of this cmd, the 2nd request may end up overwriting the first request, causing FW cmd corruption. This patch reverts the offending commit and hence fixes the regression.

I've put them through a decent amount of testing prior to sending the pull request due to that. There are still a few fixups that I know are coming, but I wanted to go ahead and get the big, sizable chunk into your hands sooner rather than waiting for those last few fixups. Of note is the fact that this creates what is intended to be a temporary area in the drivers/staging tree specifically for some cleanups and additions that are coming for the RDMA stack. We deprecated two drivers (ipath and amso1100) and are waiting to hear back if we can deprecate another one (ehca). We also put Intel's new hfi1 driver into this area because it needs to be refactored and a transfer library created out of the factored out code, and then it and the qib driver and the soft-roce driver should all be modified to use that library. I expect drivers/staging/rdma to be around for three or four kernel releases and then to go away as all of the work is completed and final deletions of deprecated drivers are done. Summary of changes for 4.3: - Create drivers/staging/rdma - Move amso1100 driver to staging/rdma and schedule for deletion - Move ipath driver to staging/rdma and schedule for deletion - Add hfi1 driver to staging/rdma and set TODO for move to regular tree - Initial support for namespaces to be used on RDMA devices - Add RoCE GID table handling to the RDMA core caching code - Infrastructure to support handling of devices with differing read and write scatter gather capabilities - Various iSER updates - Kill off unsafe usage of global mr registrations - Update SRP driver - Misc mlx4 driver updates - Support for the mr_alloc verb - Support for a netlink interface between kernel and user space cache daemon to speed path record queries and route resolution - Ininitial support for safe hot removal of verbs devices" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (136 commits) IB/ipoib: Suppress warning for send only join failures IB/ipoib: Clean up send-only multicast joins IB/srp: Fix possible protection fault IB/core: Move SM class defines from ib_mad.h to ib_smi.h IB/core: Remove unnecessary defines from ib_mad.h IB/hfi1: Add PSM2 user space header to header_install IB/hfi1: Add CSRs for CONFIG_SDMA_VERBOSITY mlx5: Fix incorrect wc pkey_index assignment for GSI messages IB/mlx5: avoid destroying a NULL mr in reg_user_mr error flow IB/uverbs: reject invalid or unknown opcodes IB/cxgb4: Fix if statement in pick_local_ip6adddrs IB/sa: Fix rdma netlink message flags IB/ucma: HW Device hot-removal support IB/mlx4_ib: Disassociate support IB/uverbs: Enable device removal when there are active user space applications IB/uverbs: Explicitly pass ib_dev to uverbs commands IB/uverbs: Fix race between ib_uverbs_open and remove_one IB/uverbs: Fix reference counting usage of event files IB/core: Make ib_dealloc_pd return void IB/srp: Create an insecure all physical rkey only if needed ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mlx4 network driver was registered in the context of the 'add' function of the core driver (called when HW should be registered). This makes the netdev event NETDEV_REGISTER to be sent in a context where the answer to get_protocol_dev() callback returns NULL. This may be confusing to listeners of netdev events.

| * | MIPS: Remove all the uses of custom gpio.hAlban Bedel2015-09-031-0/+2

However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

I've heard rumblings that the lightweight tunnels infrastructure has been voted networking change of the year. But what do I know? 1) Add conntrack support to openvswitch, from Joe Stringer. 2) Initial support for VRF (Virtual Routing and Forwarding), which allows the segmentation of routing paths without using multiple devices. There are some semantic kinks to work out still, but this is a reasonably strong foundation. From David Ahern. 3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov. 4) Ignore route nexthops with a link down state in ipv6, just like ipv4. From Andy Gospodarek. 5) Remove spinlock from fast path of act_gact and act_mirred, from Eric Dumazet. 6) Document the DSA layer, from Florian Fainelli. 7) Add netconsole support to bcmgenet, systemport, and DSA. Also from Florian Fainelli. 8) Add Mellanox Switch Driver and core infrastructure, from Jiri Pirko. 9) Add support for "light weight tunnels", which allow for encapsulation and decapsulation without bearing the overhead of a full blown netdevice. From Thomas Graf, Jiri Benc, and a cast of others. 10) Add Identifier Locator Addressing support for ipv6, from Tom Herbert. 11) Support fragmented SKBs in iwlwifi, from Johannes Berg. 12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia. 13) Add BQL support to 3c59x driver, from Loganaden Velvindron. 14) Stop using a zero TX queue length to mean that a device shouldn't have a qdisc attached, use an explicit flag instead. From Phil Sutter. 15) Use generic geneve netdevice infrastructure in openvswitch, from Pravin B Shelar. 16) Add infrastructure to avoid re-forwarding a packet in software that was already forwarded by a hardware switch. From Scott Feldman. 17) Allow AF_PACKET fanout function to be implemented in a bpf program, from Willem de Bruijn" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1458 commits) netfilter: nf_conntrack: make nf_ct_zone_dflt built-in netfilter: nf_dup{4, 6}: fix build error when nf_conntrack disabled net: fec: clear receive interrupts before processing a packet ipv6: fix exthdrs offload registration in out_rt path xen-netback: add support for multicast control bgmac: Update fixed_phy_register() sock, diag: fix panic in sock_diag_put_filterinfo flow_dissector: Use 'const' where possible. flow_dissector: Fix function argument ordering dependency ixgbe: Resolve "initialized field overwritten" warnings ixgbe: Remove bimodal SR-IOV disabling ixgbe: Add support for reporting 2.5G link speed ixgbe: fix bounds checking in ixgbe_setup_tc for 82598 ixgbe: support for ethtool set_rxfh ixgbe: Avoid needless PHY access on copper phys ixgbe: cleanup to use cached mask value ixgbe: Remove second instance of lan_id variable ixgbe: use kzalloc for allocating one thing flow: Move __get_hash_from_flowi{4,6} into flow_dissector.c ixgbe: Remove unused PCI bus types ...
| * | net: fec: clear receive interrupts before processing a packetRussell King2015-09-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch just to re-submit the patch "db3421c114cfa6326" because the patch "4d494cdc92b3b9a0" remove the change. Clear any pending receive interrupt before we process a pending packet. This helps to avoid any spurious interrupts being raised after we have fully cleaned the receive ring, while still allowing an interrupt to be raised if we receive another packet. The position of this is critical: we must do this prior to reading the next packet status to avoid potentially dropping an interrupt when a packet is still pending.

Anjali fixes a bug in i40e where the port is not receiving multicast or VLAN tagged packets in promiscuous mode. Which can occur when a software bridge is created on top of the device. Don adds support in ixgbe that indicates the presence of management firmware. Added support for entering low power link up state on devices that support it when the device is closing or suspending. Updated the driver to report unknown bus speed and width since IOSF does not report a PCIe bus speed or width for X550 devices. Also added the new bus type for integrated I/O interface (IOSF). Cleaned up of redundant code in ixgbe. Mark adds support for UDP-encapsulation transmit checksum and for VXLAN receive offloads. Introduces a helper function to do the register access and processing to avoid needless PHY access on copper PHYs. Added support for reporting 2.5G link speed. Fixed warnings resulting from redundant initializations of the get_bus_info field. Maninder Singh updates the ixgbe driver to use kzalloc instead of kcalloc for allocation of one thing. Tom Barbette adds support for ethtool to change the rxfh indirection table and/or key using ethtool interface. Emil resolves an issue where users were not able to dynamically set number of queues for 82598 via ethtool -L. Alex Williamson removes bimodal SR-IOV disabling behavior since it is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. ==================== Signed-off-by: David S.

If max_vfs was specified, the SR-IOV state is disabled, removing the VFs. The occurs regardless of whether the VF count was later modified through sysfs. If however max_vfs is zero, such as by not specifying the module parameter, the VFs persist after the PF is unbound from ixgbe. If the PF is then bound to vfio-pci to be assigned to a VM, the PF is non-functional. >From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV sysfs callback operation") clearly intended this alternate behavior, but probably didn't realize the PF doesn't work in this mode. This bimodal behavior is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. Remove this behavior so that VFs are removed and the PF is functional for other uses after unbind, regardless of the way VFs are enabled.

Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing.

This can occur when a SW bridge is created on top of the device. This also fixes issues where the promiscuous behavior setting was not being preserved across a reset caused by features being enabled or disabled. We are using defport instead of doing a true promiscuous mode because we do not need to receive the SRIOV or VMDq VSI directed traffic which would suck up bandwidth and is really not intended for the SW bridge. In addition, with defport we get VLAN promiscuous behavior which is not possible from the VSI level promiscuous setting.
