This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- trusty' to 'verification-done-trusty'. If the problem still exists, change the tag 'verification-needed-trusty' to 'verification-failed- trusty'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The dev_disable_lro warning is happening due to some logic issues in the features code. The LRO on the VLAN (bond0.200, e.g.) that's being warned about does end up being disabled by a NETDEV_FEAT_CHANGE callback when the underlying bond0's features are updated, so the warning is spurious. Tracing the dev_disable_lro -> netdev_update_features for the bond0.2004 VLAN, I see: name="bond0" feat=219db89 hw_feat=20219cbe9 want_feat=20219cbe9 vlan_feat=198069 NETIF_F_LRO = 0x8000 dev_disable_lro wanted_features &= ~NETIF_F_LRO bond0.2004 wanted_features = 0x200194869# no LRO __netdev_update_features features = netdev_get_wanted_features return (dev->features & ~dev->hw_features) | dev->wanted_features; (0x19d809 & ~0x23839487b) | 0x200194869 ^LRO ^no LRO^no LRO 0x9000 | 0x200194869 $2 = 0x20019d869 ^ LRO vlan_dev_fix_features(dev, 0x20019d869) # has LRO struct net_device *real_dev = vlan_dev_priv(dev)->real_dev; netdev_features_t old_features = features; features &= real_dev->vlan_features;# 0x198069 has LRO features |= NETIF_F_RXCSUM; # 0x100198069 has LRO features &= real_dev->features; # 0x198009 has LRO features |= old_features & NETIF_F_SOFT_FEATURES; # save GSO / GRO features |= NETIF_F_LLTX; return features; # will have LRO So, basically, LRO is set in the underlying bond0's features, so it ends up being kept in the VLAN device's features even though it wasn't in wanted_features. Later, dev_disable_lro will call dev_disable_lro on all the lower devices (the bond0 in this case), and the update of features for the bond0 will issue a NETDEV_FEAT_CHANGE callback to the bond0.2004 VLAN, which will then set the features correctly. The Ubuntu 3.13 __netdev_update_features (called by dev_disable_lro via netdev_update_features) lacks additional logic found in later kernels to sync the features to lower devices. That presumably triggers the NETDEV_FEAT_CHANGE within the call to __netdev_update_features so that the bond0.2004 VLAN is updated before we return back to dev_disable_lro (but I haven't verified this). I suspect the fix to eliminate the warning is to apply the "sync_lower:" block from a later kernel __netdev_update_features to 3.13, along with the netdev_sync_lower_features function it uses. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1771480 Title: WARNING: CPU: 28 PID: 34085 at /build/linux- 90Gc2C/linux-3.13.0/net/core/dev.c:1433 dev_disable_lro+0x87/0x90() Status in linux package in Ubuntu: Incomplete Bug description: I have multiple instances of this dev_disable_lro error in kern.log.
