2019-06-26net: hns3: code optimizaition of hclge_handle_hw_ras_error()Weihang Li
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 Shen
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. This patch fixes it by recording the VLAN ID delete failed, and removes them again when reset complete.

2019-06-26bonding: Always enable vlan tx offloadYueHaibing
We build vlan on top of bonding interface, which vlan offload is off, bond mode is 802.3ad (LACP) and xmit_hash_policy is BOND_XMIT_POLICY_ENCAP34. Because vlan tx offload is off, vlan tci is cleared and skb push the vlan header in validate_xmit_vlan() while sending from vlan devices. Then in bond_xmit_hash, __skb_flow_dissect() fails to get information from protocol headers encapsulated within vlan, because 'nhoff' is points to IP header, so bond hashing is based on layer 2 info, which fails to distribute packets across slaves. This patch always enable bonding's vlan tx offload, pass the vlan packets to the slave devices with vlan tci, let them to handle vlan implementation.

Currently, each xdp samples are inconsistent in the use. Most of the samples fetch the interface with it's name. (ex. xdp1, xdp2skb, xdp_redirect_cpu, xdp_sample_pkts, etc.) But some of the xdp samples are fetching the interface with ifindex by command argument.

2019-06-26HID: intel-ish-hid: fix wrong driver_data usageHyungwoo Yang
Currently, in suspend() and resume(), ishtp client drivers are using driver_data to get "struct ishtp_cl_device" object which is set by bus driver. It's wrong since the driver_data should not be owned bus. driver_data should be owned by the corresponding ishtp client driver. Due to this, some ishtp client driver like cros_ec_ishtp which uses its driver_data to transfer its data to its child doesn't work correctly. So this patch removes setting driver_data in bus drier and instead of using driver_data to get "struct ishtp_cl_device", since "struct device" is embedded in "struct ishtp_cl_device", we introduce a helper function that returns "struct ishtp_cl_device" from "struct device".

2019-06-26netfilter: ctnetlink: Fix regression in conntrack entry deletionFelix Kaechele
Commit f8e608982022 ("netfilter: ctnetlink: Resolve conntrack L3-protocol flush regression") introduced a regression in which deletion of conntrack entries would fail because the L3 protocol information is replaced by AF_UNSPEC. As a result the search for the entry to be deleted would turn up empty due to the tuple used to perform the search is now different from the tuple used to initially set up the entry. For flushing the conntrack table we do however want to keep the option for nfgenmsg->version to have a non-zero value to allow for newer user-space tools to request treatment under the new behavior. With that it is possible to independently flush tables for a defined L3 protocol. This was introduced with the enhancements in in commit 59c08c69c278 ("netfilter: ctnetlink: Support L3 protocol-filter on flush"). Older user-space tools will retain the behavior of flushing all tables regardless of defined L3 protocol.

2019-06-25tc-testing: Restore original behaviour for namespaces in tdcLucas Bates
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'.

2019-06-25dm init: remove trailing newline from calls to DMERR() and DMINFO()Stephen Boyd
These printing macros already add a trailing newline, so having another one here just makes for blank lines when these prints are enabled. Remove these needless newlines.

2019-06-25ath10k: Add WMI diag fw logging support for WCN3990Govind Singh
Integrated WiFi chipset ex:WCN399x supports fw logging using WMI copy engine and shared mem DIAG based fw logging. By default shared mem DIAG based fw logging is enabled. To support WMI copy engine based fw logging add QMI control message to enable WMI copy engine based fw logging. Enable WMI based fw logging using fw_diag_log module parameter. insmod ath10k_core.ko fw_diag_log=1 DIAG utility(https://github.com/andersson/diag) implements extraction of diagnostics related messages between application processor and various subsystems while shared mem DIAG based fw logging is enabled.

2019-06-25ath10k: add report MIC error for sdio chipWen Gong
Firmware will report flag with HTT_RX_IND_MPDU_STATUS_TKIP_MIC_ERR if MIC error, the flag will be used in mac80211. ieee80211_rx_h_michael_mic_verify will check the flag and start TKIP countermeasures. Now countermeasure tests pass both with WPA only and WPA2/WPA mixed mode. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.

2019-06-25ath10k: add support for controlling tx power to a stationAshok Raj Nagarajan
This patch will add the support to control the transmit power for traffic to a station associated with the AP. Underlying firmware will enforce that the maximum tx power will be based on the regulatory requirements. If the user given transmit power is greater than the allowed tx power in the given channel, then the firmware will use the maximum tx power in the same channel. Max and Min tx power values will depends on no of tx chain masks, for QCA9984 allowed tx power range values from 6 to 23. When 0 is sent to the firmware as tx power, it will revert to the default tx power for the station.

2019-06-25ath10k: Add peer delete response eventDundi Raviteja
Peer creation in firmware fails if last peer deletion is still in progress. The firmware sends a peer delete response event if it advertises the service WMI_SERVICE_SYNC_DELETE_CMDS. This peer delete response event is used to synchronize the peer deletion. Add peer delete response event and wait for the event after deleting every peer from host driver to synchronize with firmware.

2019-06-25ath10k: fix PCIE device wake up failedMiaoqing Pan
Observed PCIE device wake up failed after ~120 iterations of soft-reboot test. The error message is "ath10k_pci 0000:01:00.0: failed to wake up device : -110" The call trace as below: ath10k_pci_probe -> ath10k_pci_force_wake -> ath10k_pci_wake_wait -> ath10k_pci_is_awake Once trigger the device to wake up, we will continuously check the RTC state until it returns RTC_STATE_V_ON or timeout. But for QCA99x0 chips, we use wrong value for RTC_STATE_V_ON. Occasionally, we get 0x7 on the fist read, we thought as a failure case, but actually is the right value, also verified with the spec. So fix the issue by changing RTC_STATE_V_ON from 0x5 to 0x7, passed ~2000 iterations.
