Only first fragment has the sport/dport information, not the following ones. If we want consistent hash for all fragments, we need to ignore ports even for first fragment. This bug is visible for IPv6 traffic, if incoming fragments do not have a flow label, since skb_get_hash() will give different results for first fragment and following ones. It is also visible if any routing rule wants dissection and sport or dport. See commit 5e5d6fed3741 ("ipv6: route: dissect flow in input path if fib rules need it") for details.

2018-11-09Merge branch 'ptp-more-accurate-PHC-system-clock-synchronization'David S. Miller
Miroslav Lichvar says: ==================== More accurate PHC<->system clock synchronization RFC->v1: - added new patches - separated PHC timestamp from ptp_system_timestamp - fixed memory leak in PTP_SYS_OFFSET_EXTENDED - changed PTP_SYS_OFFSET_EXTENDED to work with array of arrays - fixed PTP_SYS_OFFSET_EXTENDED to break correctly from loop - fixed timecounter updates in drivers - split gettimex in igb driver - fixed ptp_read_* functions to be available without CONFIG_PTP_1588_CLOCK This series enables a more accurate synchronization between PTP hardware clocks and the system clock. The first two patches are minor cleanup/bug fixes. The third patch adds an extended version of the PTP_SYS_OFFSET ioctl, which returns three timestamps for each measurement. The idea is to shorten the interval between the system timestamps to contain just the reading of the lowest register of the PHC in order to reduce the error in the measured offset and get a smaller upper bound on the maximum error. The fourth patch deprecates the original gettime function. The remaining patches update the gettime function in order to support the new ioctl in the e1000e, igb, ixgbe, and tg3 drivers. Tests with few different NICs in different machines show that: - with an I219 (e1000e) the measured delay was reduced from 2500 to 1300 ns and the error in the measured offset, when compared to the cross timestamping supported by the driver, was reduced by a factor of 5 - with an I210 (igb) the delay was reduced from 5100 to 1700 ns - with an I350 (igb) the delay was reduced from 2300 to 750 ns - with an X550 (ixgbe) the delay was reduced from 1950 to 650 ns - with a BCM5720 (tg3) the delay was reduced from 2400 to 1200 ns ==================== Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2018-11-09ptp: add PTP_SYS_OFFSET_EXTENDED ioctlMiroslav Lichvar
The PTP_SYS_OFFSET ioctl, which can be used to measure the offset between a PHC and the system clock, includes the total time that the driver needs to read the PHC timestamp. This typically involves reading of multiple PCI registers (sometimes in multiple iterations) and the register that contains the lowest bits of the timestamp is not read in the middle between the two readings of the system clock. This asymmetry causes the measured offset to have a significant error. Introduce a new ioctl, driver function, and helper functions, which allow the reading of the lowest register to be isolated from the other readings in order to reduce the asymmetry. The ioctl returns three timestamps for each measurement: - system time right before reading the lowest bits of the PHC timestamp - PHC time - system time immediately after reading the lowest bits of the PHC timestamp Cc: Richard Cochran <richardcochran@gmail.com> Cc: Jacob Keller <jacob.e.keller@intel.com> Cc: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com> Signed-off-by: David S.

Global reset: triggered by writing to register. Reset all hardware unit, which affects all the PF and VF. 7. IMP reset: triggered by IMU(Intelligent Management Unit) when IMP is not longer feeding IMU's watchdog. IMU will reload the IMP firmware and IMP will perform global reset after firmware reloading, which affects all the PF and VF. Current driver only support PF/VF reset, incomplete core and global reset(lacking the vf reset handling). So this patchset adds complete reset support in hns3 driver.

2018-11-09net: hns3: implement the IMP reset processing for PFHuazhong Tan
The current code only print the prompt message after receiving the IMP reset interrupt and does not perform the corresponding driver reset operation. This patch implements the missing IMP reset handling in the driver. 1. The driver sets the HCLGE_STATE_CMD_DISABLE to stop sending command after receiving the IMP reset interrupt. 2. The driver needs to notify the hardware to reload the IMP firmware. 3. The IMP firmware reloading makes the reset time of hardware longer, so it is necessary to extend the driver's waiting time to wait for the hardware reset to complete. 4. In hclge_check_event_cause, IMP reset event should have higher priority than other events. Also, after clearing HCLGE_STATE_CMD_DISABLE in the hclge_cmd_init(), it needs to check whether there is a pending reset, if so, just set the HCLGE_STATE_CMD_DISABLE back and return.

2018-11-09net: hns3: add reset handling for VF when doing Core/Global/IMP resetHuazhong Tan
When a Core/Global/IMP reset occurs, the hardware sets the reset status register of all PF/VF and reports a reset interrupt to all PF/VF and firmware. When receiving the reset interrupt: 1. The firmware will wait for 100 ms before resetting the hardware and clear the reset status register of all PF when hardware reset is done. 2. The PF/VF driver needs to down the netdev within 100 ms and then wait for hardware reset to finish. 3. After firmware clearing the reset status register of all PF, the PF driver reinitializes the hardware and clear the reset status register of it's VF. 4. After PF driver clearing the reset status register of VF, the VF driver reinitializes the hardware. This patch mainly add handling for the step 4.

2018-11-09net: hns3: add reset handling for VF when doing PF resetHuazhong Tan
When PF performs a function reset, the hardware will reset both PF and all the VF belong to this PF. Hence, both PF's driver and VF's driver need to perform corresponding reset operations. Before PF driver asserting function reset to hardware, it firstly set up VF's hardware reset status, and inform the VF driver with HNAE3_VF_PF_FUNC_RESET, then VF driver sets this reset type to reset_pending and shechule reset task to stop IO and waits for the hardware reset status to clear. When PF driver has reinitialized the hardware and is ready to process mailbox from VF, PF driver clears VF's hardware reset status for VF to continue its reset process. Also, this patch uses readl_poll_timeout to simplify the hardware reset status waitting.

2018-11-09net: hns3: adjust VF's reset processHuazhong Tan
Currently when VF need to reset itself, it will send a cmd to PF, after receiving the VF reset requset, PF sends a cmd to inform VF to enter the reset process and send a cmd to firmware to do the actual reset for the VF, it is possible that firmware has resetted the VF, but VF has not entered the reset process, which may cause IO not stopped problem when firmware is resetting VF. This patch fixes it by adjusting the VF reset process, when VF need to reset itself, it will enter the reset process first, and it will tell the PF to send cmd to firmware to reset itself. Add member reset_pending to struct hclgevf_dev, which indicates that there is reset event need to be processed by the VF's reset task, and the VF's reset task chooses the highest-level one and clears other low-level one when it processes reset_pending. hclge_inform_reset_assert_to_vf function is unused now, but it will be used to support the PF reset with VF working, so declare it in the header file.

2018-11-09net: aquantia: fixed enable unicast on 32 macvlanIgor Russkikh
Fixed a condition mistake due to which macvlans unicast item number 32 was not added in the unicast filter. The consequence is that when exactly 32 macvlans are created on NIC, the last created macvlan receives no traffic because its MAC was not registered in HW.

2018-11-09net: aquantia: fix potential IOMMU fault after driver unbindDmitry Bogdanov
IOMMU fault may occurr on unbind/bind or if_down/if_up sequence. Although driver disables the rings on down, this is not enough. Due to internal HW design, during subsequent initialization NIC sometimes may reuse RX descriptors cache and write to the host memory from the descriptor cache. That's get catched by IOMMU on host. This patch invalidates the descriptor cache in NIC on interface down to prevent writing to the cached descriptors and to the memory pointed in those descriptors.

2018-11-09net: aquantia: synchronized flow control between mac/phyIgor Russkikh
Flow control statuses were not synchronized between blocks, that caused packets/link drop on some corner cases, when MAC sent PFC although Phy was not expecting these to come. Driver should readout the negotiated FC from phy and configure RX block accordigly. This is done on each link change event with information from FW.

2018-11-09cxgb4vf: fix memleak in mac_hlist initializationArjun Vynipadath
mac_hlist was initialized during adapter_up, which will be called every time a vf device is first brought up, or every time when device is brought up again after bringing all devices down. This means our state of previous list is lost, causing a memleak if entries are present in the list. To fix that, move list init to the condition that performs initial one time adapter setup.
