2017-09-20net: fec: only check queue 0 if RXF_0/TXF_0 interrupt is setTroy Kisky1-2/+2
Before queue 0 was always checked if any queue caused an interrupt. It is better to just mark queue 0 if queue 0 has caused an interrupt. Signed-off-by: Troy Kisky <[email protected]> Acked-by: Fugang Duan <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2017-09-19net: emac: Fix napi poll list corruptionChristian Lamparter1-2/+1
This patch is pretty much a carbon copy of commit 3079c652141f ("caif: Fix napi poll list corruption") with "caif" replaced by "emac". The commit d75b1ade567f ("net: less interrupt masking in NAPI") breaks emac. It is now required that if the entire budget is consumed when poll returns, the napi poll_list must remain empty. However, like some other drivers emac tries to do a last-ditch check and if there is more work it will call napi_reschedule and then immediately process some of this new work. Should the entire budget be consumed while processing such new work then we will violate the new caller contract. This patch fixes this by not touching any work when we reschedule in emac.

2017-09-18net: systemport: Fix 64-bit statistics dependencyFlorian Fainelli1-20/+32
There are several problems with commit 10377ba7673d ("net: systemport: Support 64bit statistics", first one got fixed in 7095c973453e ("net: systemport: Fix 64-bit stats deadlock"). The second problem is that this specific code updates the stats64.tx_{packets,bytes} from ndo_get_stats64() and that is what we are returning to ethtool -S. If we are not running a tool that involves calling ndo_get_stats64(), then we won't get updated ethtool stats. The solution to this is to update the stats from both call sites, factoring that into a specific function, While at it, don't just check the sizeof() but also the type of the statistics in order to use the 64-bit stats seqlock.

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.

2017-09-15net: 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.

2017-09-12mlxsw: 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.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2017-09-05 This series contains fixes for i40e only. These two patches fix an issue where our nvmupdate tool does not work on RHEL 7.4 and newer kernels, in fact, the use of the nvmupdate tool on newer kernels can cause the cards to be non-functional unless these patches are applied. Anjali reworks the locking around accessing the NVM so that NVM acquire timeouts do not occur which was causing the failed firmware updates. Jake correctly updates the wb_desc when reading the NVM through the AdminQ. ==================== Signed-off-by: David S. Miller <[email protected]>

When introducing the functions to read the NVM through the AdminQ, we did not correctly mark the wb_desc.

2017-09-05i40e: 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.

2017-09-05gianfar: Fix Tx flow control deactivationClaudiu Manoil1-1/+1
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.
