2019-06-26net: hns3: add exception handling when enable NIC HW error interruptsWeihang Li1-3/+5
If we failed to enable NIC HW error interrupts during client initialization in some cases, we should do exception handling to clear flags and free the resources.

2019-06-26net: hns3: fixes wrong place enabling ROCE HW error when loadingHuazhong Tan1-6/+8
The ROCE HW errors should only be enabled when initializing ROCE's client, the current code enable it no matter initializing NIC or ROCE client. So this patch fixes it.

2019-06-26net: hns3: remove override_pci_need_resetWeihang Li3-6/+2
We add override_pci_need_reset to prevent redundant and unwanted PF resets if a RAS error occurs in commit 69b51bbb03f7 ("net: hns3: fix to stop multiple HNS reset due to the AER changes"). Now in HNS3 driver, we use hw_err_reset_req to record reset level that we need to recover from a RAS error. This variable cans solve above issue as override_pci_need_reset, so this patch removes override_pci_need_reset.

2019-06-26net: hns3: code optimizaition of hclge_handle_hw_ras_error()Weihang Li1-12/+12
This patch optimizes hclge_handle_hw_ras_error() to make the code logic clearer. 1. If there was no NIC or Roce RAS when we read HCLGE_RAS_PF_OTHER_INT_STS_REG, we return directly. 2. Because NIC and Roce RAS may occurs at the same time, so we should check value of revision at first before we handle Roce RAS instead of only checking it in branch of no NIC RAS is detected. 3. Check HCLGE_STATE_RST_HANDLING each time before we want to return PCI_ERS_RESULT_NEED_RESET. 4. Remove checking of HCLGE_RAS_REG_NFE_MASK and HCLGE_RAS_REG_ROCEE_ERR_MASK because if hw_err_reset_req is not zero, it proves that we have set it in handling of NIC or Roce RAS.

2019-06-26net: hns3: sync VLAN filter entries when kill VLAN ID failedJian Shen4-16/+112
When HW is resetting, firmware is unable to handle commands from driver. So if remove VLAN device from stack at this time, it will fail to remove the VLAN ID from HW VLAN filter, then the VLAN filter status is unsynced with stack.

2019-06-25tipc: simplify stale link failure criteriaJon Maloy1-7/+2
In commit a4dc70d46cf1 ("tipc: extend link reset criteria for stale packet retransmission") we made link retransmission failure events dependent on the link tolerance, and not only of the number of failed retransmission attempts, as we did earlier. This works well. However, keeping the original, additional criteria of 99 failed retransmissions is now redundant, and may in some cases lead to failure detection times in the order of minutes instead of the expected 1.5 sec link tolerance value. We now remove this criteria altogether. Acked-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-25tc-testing: Restore original behaviour for namespaces in tdcLucas Bates8-20/+296
This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.

Collision of writing rf registers could occur if the driver writes rf registers by direct write while the hardware is writing other rf registers by pi write simultaneously. Hardware pi write can be triggered by rf calibrations sometimes, so the driver can not always write rf registers by direct write protection. Direct write protection can make sure that there is no hardware pi write during the direct write.

When the device is disconnected while passing traffic it is possible to receive out of order urbs causing a memory leak since the skb linked to the current tx urb is not removed. Fix the issue deallocating the skb cleaning up the tx ring.

2019-06-25mt7601u: do not schedule rx_tasklet when the device has been disconnectedLorenzo Bianconi1-15/+18
Do not schedule rx_tasklet when the usb dongle is disconnected. Moreover do not grub rx_lock in mt7601u_kill_rx since usb_poison_urb can run concurrently with urb completion and we can unlink urbs from rx ring in any order. This patch fixes the common kernel warning reported when the device is removed.

Firmware can send invalid command response, the processing of which can attempt to modify unexpected context and cause issues. To fix this, driver should check that the command response ID is same as the one it downloaded, and ignore processing of invalid response.

In set_mac_address, driver check for interfaces with same bss_type For first STA entry, this would return 3 interfaces since all priv's have bss_type as 0 due to kzalloc. Thus mac address gets changed for STA unexpected. This patch adds check for first STA and avoids mac address change. This patch also adds mac_address change for p2p based on bss_num type.

Unadorned '%p' has restrictive policies these days, such that it usually just prints garbage at early boot (see Documentation/core-api/printk-formats.rst, "kernel will print ``(ptrval)`` until it gathers enough entropy"). Annotating with %pK (for "kernel pointer") allows the kptr_restrict sysctl to control printing policy better. We might just as well drop this message entirely, but this fix was easy enough for now.
