* net: hns3: optimize the filter table entries handling when resettingJian Shen2020-04-268-105/+94
| | | | | | | | | | | | | | | | | | | 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. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed.

* net: hns3: use mutex vport_lock instead of mutex umv_lockJian Shen2020-04-262-13/+19
| | | | | | | | | | | | | | | | | | Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. 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. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.

* net: hns3: refactor the promisc mode settingJian Shen2020-04-268-46/+122
| | | | | | | | | | | | | | | As the HNS3 driver doesn't update the MAC address directly in function hns3_set_rx_mode() now, it can't know whether the MAC table is full from __dev_uc_sync() and __dev_mc_sync(), so it's senseless to handle the overflow promisc here. This patch removes the handle of overflow promisc from function hns3_set_rx_mode(), and updates the promisc mode in the service task.

* net: hns3: refactor the MAC address configureJian Shen2020-04-266-218/+860
| | | | | | | | | | | | | | | | | | | | | | | | Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). 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.

| | | | | | | | | | | | | Currently, firmware helps manage the unicast MAC VLAN table space for each PF. PF just needs to tell firmware its wanted space when initializing, and unnecessary to free it when un-intializing.

Therefore, an allocation failure of Rx SKBs is relatively benign. However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing.

Fix this by adding debugfs entries only after wiphy_register(). This requires some changes in the rate control code since it currently adds debugfs at alloc time, which can no longer be done after the reordering.

And this happens in most cases where WRDS is disabled, causing the WGDS without WRDS check and issue an error. To avoid this issue, we change the check so that we only considered it an error if the WRDS entry doesn't exist. If the entry (or the selected profile is disabled for any other reason), we just silently ignore WGDS.

However, the firmware API and queue allocation code assumes that there are 32 queues, and if something actually attempts to use #31 this leads to a NULL-pointer dereference since it's not allocated. Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also add some code to catch this earlier in the future, if the configuration changes perhaps.

This seems to not have caused any issues right now, likely because the hardware no longer supports putting multiple entries into a single RB, and practically all of the entries should be smaller than 2k. Nevertheless, it's a bug, and we must advertise the right size to the device. Note that right now we can only tell it 2k vs. 4k, so for the cases where we have more, still use 4k. This needs to be fixed by the firmware first.

NETDEV_UNREGISTER of dummy1 notification is sent to macvlan module. 3. ->dellink() of macvlan1 is called. 4. NETDEV_UNREGISTER of macvlan1 notification is sent to bond module. 5. __bond_release_one() is called and it internally calls dev_set_mac_address(). 6. dev_set_mac_address() calls the ->ndo_set_mac_address() of macvlan1, which is macvlan_set_mac_address(). 7. macvlan_set_mac_address() calls the dev_set_mac_address() with dummy1. 8. NETDEV_CHANGEADDR of dummy1 is sent to macvlan module. 9. In the macvlan_device_event(), it calls list_first_entry_or_null(). At this point, dummy1 and macvlan1 were removed. So, list_first_entry_or_null() will return NULL.
