2018-11-09net: hns3: add PCIe FLR support for VFHuazhong Tan2-2/+64
This patch implements the .reset_prepare and .reset_done ops from pci framework to support the VF FLR. This patch uses hclgevf_set_def_reset_request() and hclgevf_reset_event() to handle FLR, so when hdev->default_reset_request is non zero, it means there is some reset requseted by hclgevf_set_def_reset_request() need to be processed. Also get the hdev from the ae_dev because hclgevf_reset_event is called with handle being NULL. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2018-11-09net: hns3: implement the IMP reset processing for PFHuazhong Tan3-9/+37
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: stop napi polling when HNS3_NIC_STATE_DOWN is setHuazhong Tan1-6/+16
When calling napi_disable during reset down process, if NAPIF_STATE_MISSED is set, napi_complete will call __napi_schedule to do the polling again. So this patch uses HNS3_NIC_STATE_DOWN to ensure the polling is not scheduled again. Also, when napi_complete returns true, it means polling is scheduled again, it is not neccssary to enable the interrupt. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2018-11-09net: hns3: add error handler for hclgevf_reset()Huazhong Tan1-14/+37
Since hclgevf_reset() may fail for some reasons, so it needs an error handler to deal with it. When VF reset failed, VF can only be restored by a higher level reset asserted by PF. So, it needs to reinitialize its command queue, then it can respond to higher level reset. Also, this patch adds error logging in the hclgevf_notify_client().

2018-11-09net: hns3: stop handling command queue while resetting VFHuazhong Tan4-1/+35
According to hardware's description, after the reset occurs, the driver needs to re-initialize the command queue before sending and receiving any commands. Therefore, the VF's driver needs to identify the command queue needs to re-initialize with HCLGEVF_STATE_CMD_DISABLE, and does not allow sending or receiving commands before the re-initialization.

2018-11-09net: hns3: add reset handling for VF when doing Core/Global/IMP resetHuazhong Tan2-12/+46
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 Tan9-20/+146
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 Tan7-48/+63
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.

When doing reset, the reset handling function only need to reinitialize hardware, it makes sense to add a function to do that job. Also the error handling of hclgevf_init_hdev is different when it is used in reset process. This patch adds reset_hdev to reinitialize hardware when resetting.

At this moment, mcast addresses are added for real device only (reserved vlans for dual-emac mode), even if a mcast address was added for some vlan only, thus ALE doesn't have corresponding vlan mcast entries after vlan socket joined multicast group. So ALE drops vlan frames with mcast addresses intended for vlans and potentially can receive mcast frames for base ndev. That's not correct. So, fix it by creating only vlan/mcast entries as requested. Patch doesn't use any additional lists and is based on device mc address list and cpsw ALE table entries.

2018-11-08geneve: Allow configuration of DF behaviourStefano Brivio1-8/+47
draft-ietf-nvo3-geneve-08 says: It is strongly RECOMMENDED that Path MTU Discovery ([RFC1191], [RFC1981]) be used by setting the DF bit in the IP header when Geneve packets are transmitted over IPv4 (this is the default with IPv6). Now that ICMP error handling is working for GENEVE, we can comply with this recommendation. Make this configurable, though, to avoid breaking existing setups. By default, DF won't be set. It can be set or inherited from inner IPv4 packets. If it's configured to be inherited and we are encapsulating IPv6, it will be set. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, apply DF setting only if (!geneve->collect_md) in geneve_xmit_skb() (Stephen Hemminger) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2018-11-08vxlan: Allow configuration of DF behaviourStefano Brivio1-1/+28
Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its value from the IPv4 inner header. If the encapsulated protocol is IPv6 and DF is configured to be inherited, always set it. For IPv4, inheriting DF from the inner header was probably intended from the very beginning judging by the comment to vxlan_xmit(), but it wasn't actually implemented -- also because it would have done more harm than good, without handling for ICMP Fragmentation Needed messages. According to RFC 7348, "Path MTU discovery MAY be used". An expired RFC draft, draft-saum-nvo3-pmtud-over-vxlan-05, whose purpose was to describe PMTUD implementation, says that "is a MUST that Vxlan gateways [...] SHOULD set the DF-bit [...]", whatever that means. Given this background, the only sane option is probably to let the user decide, and keep the current behaviour as default. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, move DF setting to if (!info) block in vxlan_xmit_one() (Stephen Hemminger) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

Colin Ian King fixes a potential null pointer dereference by adding a check in ixgbe. Also fixed the igc driver by properly assigning the return error code of a function call, so that we can properly check it. Shannon Nelson updates the ixgbe driver to not block IPsec offload when in VEPA mode, in VEB mode, IPsec offload is still blocked because the device drops packets into a black hole. Jake adds support for software timestamping for packets sent over ixgbevf. Also modifies i40e, iavf, igb, igc, and ixgbe to delay calling skb_tx_timestamp() to the latest point possible, which is just prior to notifying the hardware of the new Tx packet. Todd adds the new WoL filter flag so that we properly report that we do not support this new feature. YueHaibing from Huawei fixes the igc driver by cleaning up variables that are not "really" used. Dan Carpenter cleans up igc whitespace issues. Miroslav Lichvar fixes e1000e for potential underflow issue in the timecounter, so modify the driver to use timecounter_cyc2time() to allow non-monotonic SYSTIM readings.

2018-11-07sfc: add missing NVRAM partition types for EF10Edward Cree1-0/+7
Expose the MUM/SUC Firmware, UEFI Expansion ROM and MC Status partitions of the NIC's NVRAM as MTDs if found on the NIC. The first two are needed in order to properly update them when performing firmware updates; the MC Status partition is used to determine whether a signed firmware image was accepted or rejected by a Secure NIC.

2018-11-07tun: compute the RFS hash only if needed.Paolo Abeni1-1/+2
The tun XDP sendmsg code path, unconditionally computes the symmetric hash of each packet for RFS's sake, even when we could skip it. e.g. when the device has a single queue. This change adds the check already in-place for the skb sendmsg path to avoid unneeded hashing. The above gives small, but measurable, performance gain for VM xmit path when zerocopy is not enabled.
