net: hns3: fix invalid mutex between tc qdisc and dcb ets command issue We hope that tc qdisc and dcb ets commands can not be used crosswise. If we want to use any of the commands to configure tc, We must use the other command to clear the existing configuration. However, when we configure a single tc with tc qdisc, we can still configure it with dcb ets. Because we use mqprio_active as the tag of tc qdisc configuration, but with dcb ets, we do not check mqprio_active. This patch fix this issue by check mqprio_active before executing the dcb ets command. and add dcb_ets_active to replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE at the hclge layer, Fixes: cacde272dd00 ("net: hns3: Add hclge_dcb module for the support of DCB feature") Signed-off-by: Jijie Shao <shaojijie@huawei.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

When a global reset was triggered, the hardware vlan table and the soft recorded vlan information will be cleared by PF, and restored them until VFs were ready. There is a short time window between the table had been cleared and before table restored.

There is a problem that if the register number queried from firmware is larger than data number of struct mac_stats, it will cause a copy overflow. So if the firmware adds more mac statistics in later version, it is not compatible with driver of old version. To fix this problem, the number of copied data needs to be used the minimum value between the register number queried from firmware and data number of struct mac_stats.

Error handling (i.e. error identification, clearing error sources and initiation of recovery) is done in context of reset task. If certain hardware errors get delivered during driver init time, which can cause driver init/loading to fail. Introduce a separate error handling task to ensure below: 1.

Now some device supports each function to bypass port VLAN filter, then each function can switch VLAN filter separately. Add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K. Furtherly, the default VLAN filter state is also changed according to whether non-zero VLAN used. Then the device can receive packet with any VLAN tag if only VLAN 0 used.

Add a state member for each flow director rule to indicate the rule state. There are 4 states: TO_ADD: the rule is waiting to add to hardware TO_DEL: the rule is waiting to remove from hardware DELETED: the rule has been removed from hardware. It's a middle state, used to remove the rule node in the fd_rule_list. ACTIVE: the rule is already added in hardware For asynchronous way, when receive a new request to add or delete flow director rule by aRFS, update the rule list, then request to schedule the service task to finish the configuration. For synchronous way, when receive a new request to add or delete flow director rule by ethtool or tc flower, configure hardware directly, then update the rule list if success.

net: hns3: refine the VLAN tag handle for port based VLAN For DEVICE_VERSION_V2, the hardware only supports max two layer VLAN tags, including port based tag inserted by hardware, tag in tx buffer descriptor(get from skb->tci) and tag in packet. For transmit packet: If port based VLAN disabled, and vf driver gets a VLAN tag from skb, the VLAN tag must be filled to the Outer_VLAN_TAG field (tag near to DMAC) of tx buffer descriptor, otherwise it may be inserted after the tag in packet. If port based VLAN enabled, and vf driver gets a VLAN tag from skb, the VLAN tag must be filled to the VLAN_TAG field (tag far to DMAC) of tx buffer descriptor, otherwise it may be conflicted with port based VLAN, and raise a hardware error. For receive packet: The hardware will strip the VLAN tags and fill them in the rx buffer descriptor, no matter port based VLAN enable or not. Because port based VLAN tag is useless for stack, so vf driver needs to discard the port based VLAN tag get from rx buffer descriptor when port based VLAN enabled. So vf must know about the port based VLAN state. For DEVICE_VERSION_V3, the hardware provides some new configuration to improve it. For transmit packet: When enable tag shift mode, hardware will handle the VLAN tag in outer_VLAN_TAG field as VLAN_TAG, so it won't conflict with port based VLAN. And hardware also make sure the tag before the tag in packet. So vf driver doesn't need to specify the tag position according to the port based VLAN state anymore. For receive packet: When enable discard mode, hardware will strip and discard the port based VLAN tag, so vf driver doesn't need to identify it from rx buffer descriptor. So modify the port based VLAN configuration, simplify the process for vf handling the VLAN tag.

net: hns3: add support for pf querying new interrupt resources For HNAE3_DEVICE_VERSION_V3, a maximum of 1281 interrupt resources are supported. To utilize these new resources, extend the corresponding field or variable to 16bit type, and remove the restriction of NIC client that only use a maximum of 65 interrupt vectors. In addition, the I/O address of the extended interrupt resources are different, so an extra handler is needed. Currently, the total number of interrupts is the sum of RoCE's number and RoCE's offset (RoCE is in front of NIC), since the number of both NIC and RoCE are same. For readability, rewrite the corresponding field of the command, rename the RoCE's offset field as the number of NIC interrupts, then the total number of interrupts is sum of the number of RoCE and NIC, and replace vport->back with hdev in hclge_init_roce_base_info() for simplifying the code.

net: hns3: optimize the filter table entries handling when resetting Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset.

Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended.

For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list.

net: hns3: refactor the precedure of PF FLR Currently, the actual work of PF FLR is handled in the reset task, which is asynchronous. So in some case, if the preparing and rebuilding are not done, then the PF FLR will trigger some problems, for example, makes hardware go into chaos. So this patch separates the process of PF FLR from reset task, and adds a semaphore to serialize this reset and others. When FLR's preparing fails, if there has other higher level reset pending or failing times less than the HCLGE_FLR_RETRY_CNT, this preparing should be retried, otherwise PF and its VF may get into wrong state. BTW, while the hardware reports misc interrupt during pcie_flr(), the driver can not receive this interrupt anymore, so disable it when hclge_flr_prepare() return, and re-enable it when enter hclge_flr_done().

net: hns3: not allow SSU loopback while execute ethtool -t dev The current loopback mode is to add 0x1F to the SMAC address as the DMAC address and enable the promiscuous mode. However, if the VF address is the same as the DMAC address, the loopback test fails. Loopback can be enabled in three places: SSU, MAC, and serdes. By default, SSU loopback is enabled, so if the SMAC and the DMAC are the same, the packets are looped back in the SSU. If SSU loopback is disabled, packets can reach MAC even if SMAC is the same as DMAC. Therefore, this patch disables the SSU loopback before the loopback test. In this way, the SMAC and DMAC can be the same, and the promiscuous mode does not need to be enabled. And this is not valid in version 0x20. This patch also uses a macro to replace 0x1F.

net: hns3: don't configure new VLAN ID into VF VLAN table when it's full VF VLAN table can only support no more than 256 VLANs. When user adds too many VLANs, the VF VLAN table will be full, and firmware will close the VF VLAN table for the function. When VF VLAN table is full, and user keeps adding new VLANs, it's unnecessary to configure the VF VLAN table, because it will always fail, and print warning message. The worst case is adding 4K VLANs, and doing reset, it will take much time to restore these VLANs, which may cause VF reset fail by timeout.

These MSIX reported hardware errors are handled using common misc. interrupt handler. Hardware error related registers cannot be cleared in context to the interrupt received as they require *heavy* access to hardware using IMP(Integrated Mangement Processor) commands. Hence, we defer the clearing of such error events till later time. Since, we have defered exact identification of errors we will have to defer the level of receovery/reset which might be required. Hence, a new reset type UNKNOWN reset has been introduced which effectively defers the assertion of the reset till we get hold of kind of errors at later time.

net: hns3: Add vport alive state checking support Currently there is no way for pf to know if a vf device is alive or not, so PF does not know which vf to notify when reset happens, or which vf's mtu is invalid when vf and pf share the same hardware mtu setting. This patch adds vport alive state checking support, in order to support the above scenario.

net: hns3: implement the IMP reset processing for PF 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.

net: hns3: add reset handling for VF when doing PF reset 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.

net: hns3: adjust VF's reset process 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.

net: hns3: add error handler for hclge_reset() When hclge_reset() is called, it may fail for several reasons. For example, an higher-level reset event occurs, memory allocation failure, hardware reset timeout, etc. Therefore, it is necessary to add corresponding error handling for these situations. 1. A high-level reset is required due to a high-level reset failure. 2. For memory allocation failure, a high-level reset is initiated by the timer to recover. The reason for using the timer is to prevent this new high-level reset to interrupt the reset process of other pf/vf; 3. For the case of hardware reset timeout, reschedule the reset task to wait for the hardware to complete the reset. For memory allocation failure and reset timeouts, in order to prevent an infinite number of scheduled reset tasks, the number of error recovery needs to be limited. This patch also add some reset related debug log printing. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net: hns3: fix for setting MTU When setting MTU, actually what we do is configuring the max frame size for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be considered. And the frame size which is less than the default value should not be set to the hardware. Because in the hardware, the the max frame size not only controls the RX packet size, but also controls the TX packet size. the RX packets whose size are greater than the setting value will be dropped. This patch fixes the bug setting a error max frame size to hardware.

net: hns3: Modify the update period of packet statistics It takes more than 200 query response messages between driver and IMP, while updating the packet statistics. It's too heavy for IMP to update it per second. Extend the update period of packet statistics data from 1 second to 300 seconds(if too long, the statistics may overflow). As a result, we need to update it while querying with ifconfig tool to keep the statistics data fresh.

net: hns3: Refactors the requested reset & pending reset handling code In exisiting code, the way to detect if driver/client reset should be executed or if hardware should be be soft resetted was overly complex. Existing code use to read the interrupt status register from task context to figure out if the interrupt source event was reset and then use clear the interrupt source for reset while waiting for the hardware to finish the reset. This behaviour again was confusing and overly complex in terms of the flow. This patch simplifies the handling of the requested reset and the pending reset(i.e. reset which have already been asserted by the software and hardware has acknowledged back to driver that it is processing the hardware reset through interrupt) Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: lipeng <lipeng321@huawei.com> Signed-off-by: David S.

net: hns3: Refactor of the reset interrupt handling logic The reset interrupt event shares common miscellaneous interrupt Vector 0. In the existing reset interrupt handling we disable the Vector 0 interrupt in misc interrupt handler and re-enable them later in context to common service task. This also means other event sources like mailbox would also be deferred or if the interrupt event was due to mailbox(which shall be supported for VF soon), it could delay the reset handling. This patch reorganizes the reset interrupt handling logic and makes it more fair to other events.
