2017-09-20net: fec: return IRQ_HANDLED if fec_ptp_check_pps_event handled itTroy Kisky1-2/+2

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.

2017-09-19net: hns3: Fixes the premature exit of loop when matching clientsLipeng1-34/+9
When register/unregister ae_dev, ae_dev should match all client in the client_list. Enet and roce can co-exists together so we should continue checking for enet and roce presence together.

Since the integration of PHYLINK, the configuration option which used to be under the PHY infrastructure menu in menuconfig ended up one level up (the network device driver section) By placing PHYLINK option right after PHYLIB entry, it broke the way Kconfig used to build the menu.

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.

This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum.

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.

2017-09-13mm: treewide: remove GFP_TEMPORARY allocation flagMichal Hocko17-30/+30
GFP_TEMPORARY was introduced by commit e12ba74d8ff3 ("Group short-lived and reclaimable kernel allocations") along with __GFP_RECLAIMABLE. It's primary motivation was to allow users to tell that an allocation is short lived and so the allocator can try to place such allocations close together and prevent long term fragmentation. As much as this sounds like a reasonable semantic it becomes much less clear when to use the highlevel GFP_TEMPORARY allocation flag. How long is temporary? Can the context holding that memory sleep? Can it take locks? It seems there is no good answer for those questions. The current implementation of GFP_TEMPORARY is basically GFP_KERNEL | __GFP_RECLAIMABLE which in itself is tricky because basically none of the existing caller provide a way to reclaim the allocated memory. So this is rather misleading and hard to evaluate for any benefits. I have checked some random users and none of them has added the flag with a specific justification. I suspect most of them just copied from other existing users and others just thought it might be a good idea to use without any measuring. This suggests that GFP_TEMPORARY just motivates for cargo cult usage without any reasoning. I believe that our gfp flags are quite complex already and especially those with highlevel semantic should be clearly defined to prevent from confusion and abuse. Therefore I propose dropping GFP_TEMPORARY and replace all existing users to simply use GFP_KERNEL. Please note that SLAB users with shrinkers will still get __GFP_RECLAIMABLE heuristic and so they will be placed properly for memory fragmentation prevention. I can see reasons we might want some gfp flag to reflect shorterm allocations but I propose starting from a clear semantic definition and only then add users with proper justification. This was been brought up before LSF this year by Matthew [1] and it turned out that GFP_TEMPORARY really doesn't have a clear semantic. It seems to be a heuristic without any measured advantage for most (if not all) its current users. The follow up discussion has revealed that opinions on what might be temporary allocation differ a lot between developers. So rather than trying to tweak existing users into a semantic which they haven't expected I propose to simply remove the flag and start from scratch if we really need a semantic for short term allocations.

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.

2017-09-13nfp: wait for board state before talking to the NSPJakub Kicinski2-23/+43
Board state informs us which low-level initialization stages the card has completed. We should wait for the card to be fully initialized before trying to communicate with it, not only before we configure passing traffic.
