Caller should know if he can call attr_set directly (when holding RTNL) or if he has to defer the att_set processing for later. This also allows drivers to sleep inside attr_set and report operation status back to switchdev core. Switchdev core then warns if status is not ok, instead of silent errors happening in drivers. Benefit from newly introduced switchdev deferred ops infrastructure. Signed-off-by:

Introduce infrastructure which will be used internally to defer ops. Note that the deferred ops are queued up and either are processed by scheduled work or explicitly by user calling deferred_process function. Signed-off-by:

this patch fixes a bug in hns driver. when we want to get statistic info by using ethtool -S, it shows us there are 3 wrong counters info. because the strings related to the registers are wrong. it needs to modify the strings which give us wrong info. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-15 This series contains updates to i40e, i40evf and ixgbe. Emil changes the ixgbe driver to disable LRO by default in favor or GRO. Mark provides two changes for ixgbe, first fixes a semaphore issue when a reset never completes, it is necessary to retake the semaphore before returning. Jesse fixes up a missing function header comment variable reference. Then enables ethtool priv flags to control flow director at runtime. Neerav changes several i40e error messages to debug only since the messages were printing when there was no functional issue and were meant for debug only. Catherine changes the i40e driver to make only X722 support 100M SGMII, since it is the only device to actually support it. Anjali modifies the i40e/i40evf driver to add writeback on ITR offload support for X722 since the device has a way to work around the descriptor writeback issue. Mitch cleans up obsolete code. Also reduces the i40evf init time by shortening up the delays in the init task to aid in performance in load/unload tests and mitigates DMAR errors in VF enable/disable tests. Shannon modifies i40e to allow flow director sideband when the device is in MFP mode and only has one partition enabled, since we still have plenty of interrupts for managing the flow director activity. Also cleaned up flow director ATR control in debugfs since the priv flag has been added to our ethtool interface. Makes several general code cleanups of redundant or unnecessary code for i40e. ==================== Signed-off-by: -

Shorten up the delays in the init task, allowing the VF driver to initialize faster. This aids performance in load/unload tests and mitigates DMAR errors in VF enable/disable tests with absurdly short delays. In the real world, the VF driver will come up more quickly. The original values were set conservatively based on what we expected from the firmware in terms of performance. Now that the driver is in use and we know how well firmware responds to our requests, we can shorten these delays. Change-ID: Ibead77d34b19e8170e667c3f58bc14748bbc5bc9 Signed-off-by:

Or Gerlitz says: ==================== Mellanox driver update, Oct 14 2015 This series contains two more patches from Eli, patch from Majd to support PCI error handlers and a fix from Jack to mlx4 VFs when probed without a provisioned mac address.

Jack Morgenstein authored
By design, when no default MAC addresses are set in the Hypervisor for VFs, the VFs are passed zero-macs. When such a MAC is received by the VF, it generates a random MAC address and registers that MAC address with the Hypervisor. This random mac generation is currently done in the mlx4_en module. There is a problem, though, if the mlx4_ib module is loaded by a VF before the mlx4_en module. In this case, for RoCE, mlx4_ib will see the un-replaced zero-mac and register that zero-mac as part of QP1 initialization. Having a zero-mac in the port's MAC table creates problems for a Baseboard Management Console. The BMC occasionally sends packets with a zero-mac destination MAC. If there is a zero-mac present in the port's MAC table, the FW will send such BMC packets to the host driver rather than to the wire, and BMC will stop working. To address this problem, we move the replacement of zero-mac addresses with random-mac addresses to procedure mlx4_slave_cap(), which is part of the driver startup for VFs, and is before activation of mlx4_ib and mlx4_en. As a result, zero-mac addresses will never be registered in the port MAC table by the driver. In addition, when mlx4_en does initialize the net device, it needs to set the NET_ADDR_RANDOM flag in the netdev structure if the address was randomly generated. This is done so that udev on the VM does not create a new device name after each VF probe (VM boot and such). To accomplish this, we add a per-port flag in mlx4_dev which gets set whenever mlx4_core replaces a zero-mac with a randomly-generated mac. This flag is examined when mlx4_en initializes the net-device. Fix was suggested by Matan Barak <matanb@mellanox.com> Signed-off-by:

This patch implement the pci_error_handlers for mlx5_core which allow the driver to recover from PCI error. Once an error is detected in the PCI, the mlx5_pci_err_detected is called and it: 1) Marks the device to be in 'Internal Error' state. 2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes with error. 3) Returns all the on going commands with error. 4) Unloads the driver. Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it enables the device and restore it's pci state. If the later succeeds, mlx5_pci_resume is called, and it loads the SW stack.

As we no longer hold listener lock in fast path, it is possible that a child is created right after listener freed its bound port, if a close() is done while incoming packets are processed. __inet_inherit_port() must detect this and return an error, so that caller can free the child earlier.

Revert the commit e2ca690b ("ipv4/icmp: redirect messages can use the ingress daddr as source"), which tried to introduce a more suitable behaviour for ICMP redirect messages generated by VRRP routers. However RFC 5798 section 8.1.1 states: The IPv4 source address of an ICMP redirect should be the address that the end-host used when making its next-hop routing decision. while said commit used the generating packet destination address, which do not match the above and in most cases leads to no redirect packets to be generated.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-13 This series contains updates to i40e, i40evf, ixgbe and fm10k. Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as __always_unused, since it is never used. Adds a member to the nvm_info struct to store OEM version info to be output either by OID or ethtool. Neerav cleans up a remaining bit shift to use BIT() macro. Mitch fixes the i40evf driver to properly handle calls to its ndo_set_mac_address() method. It did not properly check to see if the override would be allowed by the PF driver, and it never removed the old address from its filter list. Cleaned up the use of i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant since we already call it by i40e_reset_vf(). Fixed a possible panic in some circumstances where the firmware may fail to allocate a VSI for a VF by checking the return value from i40e_alloc_vf_res() and don't try to configure the device further if it failed. Greg fixes the parsing of CEE App TLVs so the caller does not have to consider whether the App came from a CEE or IEEE DCBx negotiation. Shannon moves the device ids into a standalone file due to the desire to write user-land drivers (and other requests) without needing the rest of the include files. Catherine adds the ability to save the module information from get_phy_capabilities() to be used to determine which speeds the module supports. Also cleaned up the PHY structure by removing unused members and add the ability to store the PHY capabilities reported by the firmware. Emil modifies ixgbe to ensure that flow control packets initiated by the VF are dropped and reported as spoofed. Jacob cleans up the fm10k driver to avoid buffer overflow by using sprintf(), so convert to using snprintf(). Also fixed the use of an enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED in case it ever changes from the current value of zero. v2: Dropped patch 11 of the original series, which added functions that were never used. ==================== Signed-off-by: -
