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. 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 offloadYueHaibing1-1/+1
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.

2019-06-26samples: bpf: make the use of xdp samples consistentDaniel T. Lee4-12/+42
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. This commit enables xdp samples to fetch interface with it's name without changing the original index interface fetching. (<ifname|ifindex> fetching in the same way as xdp_sample_pkts_user.c does.)

2019-06-26HID: intel-ish-hid: fix wrong driver_data usageHyungwoo Yang3-3/+17
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".

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'.

2019-06-25veth: Support bulk XDP_TXToshiaki Makita1-12/+48
XDP_TX is similar to XDP_REDIRECT as it essentially redirects packets to the device itself. XDP_REDIRECT has bulk transmit mechanism to avoid the heavy cost of indirect call but it also reduces lock acquisition on the destination device that needs locks like veth and tun. XDP_TX does not use indirect calls but drivers which require locks can benefit from the bulk transmit for XDP_TX as well. This patch introduces bulk transmit mechanism in veth using bulk queue on stack, and improves XDP_TX performance by about 9%. Here are single-core/single-flow XDP_TX test results. CPU consumptions are taken from "perf report --no-child". - Before: 7.26 Mpps _raw_spin_lock 7.83% veth_xdp_xmit 12.23% - After: 7.94 Mpps _raw_spin_lock 1.08% veth_xdp_xmit 6.10% v2: - Use stack for bulk queue instead of a global variable.

2019-06-25rt2800: do not nullify initialization vector dataStanislaw Gruszka1-5/+4
If we restart hw we should keep existing IV (initialization vector) otherwise HW encryption will be broken after restart. Also fix some coding style issues on the way. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-06-25rt2800: add pre_reset_hw callbackStanislaw Gruszka6-0/+24
Add routine to cleanup interfaces data before hw reset as ieee80211_restart_hw() will do setup interfaces again. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-06-25rt2800: initial watchdog implementationStanislaw Gruszka6-0/+67
Add watchdog for rt2800 devices. For now it only detect hung and print error. [Note: I verified that printing messages from process context is fine on MT7620 (WT3020) platform that have problem when printk is called from interrupt context].

2019-06-25rt2800: add helpers for reading dma done indexStanislaw Gruszka6-0/+52
For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE interrupts, what is rather not worth to do due to adding extra CPU load (small but still somewhat not necessary otherwise). We can just read TX DMA done indexes from registers directly. What will be used by watchdog. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-06-25rt2x00: allow to specify watchdog intervalStanislaw Gruszka2-4/+10
Allow subdriver to change watchdog interval by intialize link->watchdog_interval value before rt2x00link_register(). Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-06-25p54: remove dead branch in op_conf_tx callbackChristian Lamparter1-6/+3
This patch removes the error branch for (queue > dev->queues). It is no longer needed anymore as the "queue" value is validated by cfg80211's parse_txq_params() before the driver code gets called.
