2017-09-16mlxsw: spectrum_router: Only handle IPv4 and IPv6 eventsIdo Schimmel1-1/+2
The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family.

2017-09-16net: smsc911x: Quieten netif during suspendGeert Uytterhoeven1-1/+14
If the network interface is kept running during suspend, the net core may call net_device_ops.ndo_start_xmit() while the Ethernet device is still suspended, which may lead to a system crash. E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is driven by a PM controlled clock. If the Ethernet registers are accessed while the clock is not running, the system will crash with an imprecise external abort. As this is a race condition with a small time window, it is not so easy to trigger at will. Using pm_test may increase your chances: # echo 0 > /sys/module/printk/parameters/console_suspend # echo platform > /sys/power/pm_test # echo mem > /sys/power/state To fix this, make sure the network interface is quietened during suspend.

2017-09-13nfp: wait for the NSP resource to appear on bootJakub Kicinski3-0/+51
The control process (NSP) may take some time to complete its initialization. This is not a problem on most servers, but on very fast-booting machines it may not be ready for operation when driver probes the device. There is also a version of the flash in the wild where NSP tries to train the links as part of init. To wait for NSP initialization we should make sure its resource has already been added to the resource table. NSP adds itself there as last step of init.

2017-09-13net: bonding: fix tlb_dynamic_lb default valueNikolay Aleksandrov1-10/+7
Commit 8b426dc54cf4 ("bonding: remove hardcoded value") changed the default value for tlb_dynamic_lb which lead to either broken ALB mode (since tlb_dynamic_lb can be changed only in TLB) or setting TLB mode with tlb_dynamic_lb equal to 0. The first issue was recently fixed by setting tlb_dynamic_lb to 1 always when switching to ALB mode, but the default value is still wrong and we'll enter TLB mode with tlb_dynamic_lb equal to 0 if the mode is changed via netlink or sysfs. In order to restore the previous behaviour and default value simply remove the mode check around the default param initialization for tlb_dynamic_lb which will always set it to 1 as before.

2017-09-13mlxsw: spectrum: Prevent mirred-related crash on removalYuval Mintz1-10/+9
When removing the offloading of mirred actions under matchall classifiers, mlxsw would find the destination port associated with the offloaded action and utilize it for undoing the configuration. Depending on the order by which ports are removed, it's possible that the destination port would get removed before the source port. In such a scenario, when actions would be flushed for the source port mlxsw would perform an illegal dereference as the destination port is no longer listed. Since the only item necessary for undoing the configuration on the destination side is the port-id and that in turn is already maintained by mlxsw on the source-port, simply stop trying to access the destination port and use the port-id directly instead.

2017-09-12net: bonding: Fix transmit load balancing in balance-alb mode if specified ↵Kosuke Tatsukawa1-0/+3
by sysfs Commit cbf5ecb30560 ("net: bonding: Fix transmit load balancing in balance-alb mode") tried to fix transmit dynamic load balancing in balance-alb mode, which wasn't working after commit 8b426dc54cf4 ("bonding: remove hardcoded value"). It turned out that my previous patch only fixed the case when balance-alb was specified as bonding module parameter, and not when balance-alb mode was set using /sys/class/net/*/bonding/mode (the most common usage). In the latter case, tlb_dynamic_lb was set up according to the default mode of the bonding interface, which happens to be balance-rr. This additional patch addresses this issue by setting up tlb_dynamic_lb to 1 if "mode" is set to balance-alb through the sysfs interface. I didn't add code to change tlb_balance_lb back to the default value for other modes, because "mode" is usually set up only once during initialization, and it's not worthwhile to change the static variable bonding_defaults in bond_main.c to a global variable just for this purpose. Commit 8b426dc54cf4 also changes the value of tlb_dynamic_lb for balance-tlb mode if it is set up using the sysfs interface. I didn't change that behavior, because the value of tlb_balance_lb can be changed using the sysfs interface for balance-tlb, and I didn't like changing the default value back and forth for balance-tlb. As for balance-alb, /sys/class/net/*/bonding/tlb_balance_lb cannot be written to. However, I think balance-alb with tlb_dynamic_lb set to 0 is not an intended usage, so there is little use making it writable at this moment.

2017-09-12hv_netvsc: fix deadlock on hotplugStephen Hemminger4-45/+94
When a virtual device is added dynamically (via host console), then the vmbus sends an offer message for the primary channel. The processing of this message for networking causes the network device to then initialize the sub channels. The problem is that setting up the sub channels needs to wait until the subsequent subchannel offers have been processed. These offers come in on the same ring buffer and work queue as where the primary offer is being processed; leading to a deadlock. This did not happen in older kernels, because the sub channel waiting logic was broken (it wasn't really waiting). The solution is to do the sub channel setup in its own work queue context that is scheduled by the primary channel setup; and then happens later.

2017-09-07iwlwifi: mvm: only send LEDS_CMD when the FW supports itLuca Coelho2-1/+3
The LEDS_CMD command is only supported in some newer FW versions (e.g. iwlwifi-8000C-31.ucode), so we can't send it to older versions (such as iwlwifi-8000C-27.ucode). To fix this, check for a new bit in the FW capabilities TLV that tells when the command is supported. Note that the current version of -31.ucode in linux-firmware.git (31.532993.0) does not have this capability bit set, so the LED won't work, even though this version should support it. But we will update this firmware soon, so it won't be a problem anymore.

2017-09-06i40e: avoid NVM acquire deadlock during NVM updateAnjali Singhai Jain2-40/+60
X722 devices use the AdminQ to access the NVM, and this requires taking the AdminQ lock. Because of this, we lock the AdminQ during i40e_read_nvm(), which is also called in places where the lock is already held, such as the firmware update path which wants to lock once and then unlock when finished after performing several tasks. Although this should have only affected X722 devices, commit 96a39aed25e6 ("i40e: Acquire NVM lock before reads on all devices", 2016-12-02) added locking for all NVM reads, regardless of device family. This resulted in us accidentally causing NVM acquire timeouts on all devices, causing failed firmware updates which left the eeprom in a corrupt state. Create unsafe non-locked variants of i40e_read_nvm_word and i40e_read_nvm_buffer, __i40e_read_nvm_word and __i40e_read_nvm_buffer respectively. These variants will not take the NVM lock and are expected to only be called in places where the NVM lock is already held if needed. Since the only caller of i40e_read_nvm_buffer() was in such a path, remove it entirely in favor of the unsafe version. If necessary we can always add it back in the future. Additionally, we now need to hold the NVM lock in i40e_validate_checksum because the call to i40e_calc_nvm_checksum now assumes that the NVM lock is held. We can further move the call to read I40E_SR_SW_CHECKSUM_WORD up a bit so that we do not need to acquire the NVM lock twice. This should resolve firmware updates and also fix potential raise that could have caused the driver to report an invalid NVM checksum upon driver load.

The wrong register is checked for the Tx flow control bit, it should have been maccfg1 not maccfg2. This went unnoticed for so long probably because the impact is hardly visible, not to mention the tangled code from adjust_link(). First, link flow control (i.e. handling of Rx/Tx link level pause frames) is disabled by default (needs to be enabled via 'ethtool -A'). Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few old boards), which results in Tx flow control remaining always on once activated.
