Philippe Reynes says: ==================== net: usbnet: move to new api ethtool_{get|set}_link_ksettings The ethtool api {get|set}_settings is deprecated. On usbnet, it was often implemented with usbnet_{get|set}_settings. In this series, I add usbnet_{get|set}_link_ksettings in the first patch, then I update all the driver to use this new api, and in the last patch I remove the old api usbnet_{get|set}_settings. ==================== Signed-off-by: -

__bcmgenet_tx_reclaim() is currently summing TX bytes/packets in a way that is not SMP friendly, mutliples CPUs could run __bcmgenet_tx_reclaim() independently and still update stats->tx_bytes and stats->tx_packets, cloberring the other CPUs statistics. Fix this by tracking per RX and TX rings the number of bytes, packets, dropped and errors statistics, and provide a bcmgenet_get_stats() function which aggregates everything and returns a consistent output.

This patch adds support for ECMP hash policy choice via a new sysctl called fib_multipath_hash_policy and also adds support for L4 hashes. The current values for fib_multipath_hash_policy are: 0 - layer 3 (default) 1 - layer 4 If there's an skb hash already set and it matches the chosen policy then it will be used instead of being calculated (currently only for L4). In L3 mode we always calculate the hash due to the ICMP error special case, the flow dissector's field consistentification should handle the address order thus we can remove the address reversals. If the skb is provided we always use it for the hash calculation, otherwise we fallback to fl4, that is if skb is NULL fl4 has to be set. Signed-off-by:

wanted_features is a set of features which have to be enabled if a hardware allows that. Currently when a vlan device is created, its wanted_features is set to current features of its base device. The problem is that the base device can get new features and they are not propagated to vlan-s of this device. If we look at bonding devices, they doesn't have this problem and this patch suggests to fix this issue by the same way how it works for bonding devices. We meet this problem, when we try to create a vlan device over a bonding device. When a system are booting, real devices require time to be initialized, so bonding devices created without slaves, then vlan devices are created and only then ethernet devices are added to the bonding device. As a result we have vlan devices with disabled scatter-gather. * create a bonding device $ ip link add bond0 type bond $ ethtool -k bond0 | grep scatter scatter-gather: off tx-scatter-gather: off [requested on] tx-scatter-gather-fraglist: off [requested on] * create a vlan device $ ip link add link bond0 name bond0.10 type vlan id 10 $ ethtool -k bond0.10 | grep scatter scatter-gather: off tx-scatter-gather: off tx-scatter-gather-fraglist: off * Add a slave device to bond0 $ ip link set dev eth0 master bond0 And now we can see that the bond0 device has got the scatter-gather feature, but the bond0.10 hasn't got it. [root@laptop linux-task-diag]# ethtool -k bond0 | grep scatter scatter-gather: on tx-scatter-gather: on tx-scatter-gather-fraglist: on [root@laptop linux-task-diag]# ethtool -k bond0.10 | grep scatter scatter-gather: off tx-scatter-gather: off tx-scatter-gather-fraglist: off With this patch the vlan device will get all new features from the bonding device. Here is a call trace how features which are set in this patch reach dev->wanted_features. register_netdevice vlan_dev_init ... dev->hw_features = NETIF_F_HW_CSUM | NETIF_F_SG | NETIF_F_FRAGLIST | NETIF_F_GSO_SOFTWARE | NETIF_F_HIGHDMA | NETIF_F_SCTP_CRC | NETIF_F_ALL_FCOE; dev->features |= dev->hw_features; ... dev->wanted_features = dev->features & dev->hw_features; __netdev_update_features(dev); vlan_dev_fix_features ...

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-03-20 This series contains updates to i40e and i40evf only. Philippe Reynes updates i40e and i40evf to use the new ethtool API for {get|set}_link_ksettings. Jake provides the remaining patches in the series, starting with a fix for i40e where the firmware expected the port numbers for the offloaded UDP tunnels in Little Endian format and we were sending them in Big Endian format which put the wrong port number to be put in the UDP tunnel list. Changed the driver to use __be32 values instead of arrays for (src|dst)_ip. Refactored the exit flow of i40e_add_fdir_ethtool() which removes the dependency on having a non-zero return value. Fixed a memory leak by running kfree() and returning immediately when we fail to add flow director filter. Fixed a potential issue where could update the filter count without actually succeeding in adding a filter, by moving the ATR exit check to after we have sent the TCP/IPv4 filter to the ring successfully. Ensures that the fd_tcp_rule count is reset to 0, before we reprogram the filters so that we do not end up with a stale count which does not correctly reflect the number of programmed filters. Added a check whether we have TCP/IPv4 filters before re-enabling ATR after flushing and replaying FDIR filters. Added counters for each filter type in preparation for adding code to properly check the mask value. Fixed potential issues by explicitly checking the flow type at the start of i40e_add_fdir_ethtool(). To avoid possible memory leaks, we now unconditionally delete the old filter, even if it is identical to the new filter and ensures will always update the filters as expected. ==================== Signed-off-by: -

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree. A couple of new features for nf_tables, and unsorted cleanups and incremental updates for the Netfilter tree. More specifically, they are: 1) Allow to check for TCP option presence via nft_exthdr, patch from Phil Sutter. 2) Add symmetric hash support to nft_hash, from Laura Garcia Liebana. 3) Use pr_cont() in ebt_log, from Joe Perches. 4) Remove some dead code in arp_tables reported via static analysis tool, from Colin Ian King. 5) Consolidate nf_tables expression validation, from Liping Zhang. 6) Consolidate set lookup via nft_set_lookup(). 7) Remove unnecessary rcu read lock side in bridge netfilter, from Florian Westphal. 8) Remove unused variable in nf_reject_ipv4, from Tahee Yoo. 9) Pass nft_ctx struct to object initialization indirections, from Florian Westphal. 10) Add code to integrate conntrack helper into nf_tables, also from Florian. 11) Allow to check if interface index or name exists via NFTA_FIB_F_PRESENT, from Phil Sutter. 12) Simplify resolve_normal_ct(), from Florian. 13) Use per-limit spinlock in nft_limit and xt_limit, from Liping Zhang. 14) Use rwlock in nft_set_rbtree set, also from Liping Zhang. 15) One patch to remove a useless printk at netns init path in ipvs, and several patches to document IPVS knobs. 16) Use refcount_t for reference counter in the Netfilter/IPVS code, from Elena Reshetova. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2017-03-17 This series contains updates to mainly igb, with one fix for ixgbe. Alex does all the changes in the series, starting with adding support for DMA_ATTR_WEAK_ORDERING to improve performance on some platforms. Modified igb to use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. Modified the driver to only go through the region in the receive ring that was designated to be cleaned up, instead of going through the entire ring on cleanup. Cleaned up the transmit side, by clearing the transmit buffer_info only when resetting the rings. Added a new upper limit for receive, which is based on the size of a 2K buffer minus padding, which will allow us to support build_skb going forward. Fixed ethtool testing to only sync on the size of the frame that is being tested, instead of the entire receive buffer. Updated the handling of page addresses to always use a void pointer with the consistent name of "va" to indicate that we are working with a virtual address. Added a "chicken bit" so that we can turn off the new receive allocation feature, in the case where we need to fallback to the legacy receive path. Added support for using 3K buffers in order 1 pages the same way we were using 2K buffers in 4K pages. Added support for padding packet, since we limit the size of the frame, we are able to write to an offset within the buffer instead of having to write at the very start of the buffer. This allows us to leaving padding room for things like supporting XDP in the future. Refactored the receive buffer page management, since there are 2-3 paths that can be taken depending on what receive modes are enabled, so to improve maintainability, break out the common bits into their own functions. Add support for build_skb, again. Lastly, fixed a typo in igb and ixgbe code comments. ==================== Signed-off-by:

The previous code relied on i40e_match_fdir_input_set to determine when determining whether to free the old filter. Change this code so that we simply unconditionally delete the old filter, even if it's identical to the new filter. This ensures that we don't leak any memory, and that we always update the filters as expected. Signed-off-by:

Although we will fail the filter later due to checking flow_type which will have a bogus invalid type, it is possible future refactoring will remove this hidden failure case.

In preparation for adding code to properly check the mask values, we will need to know the number of active filters for each type. Add counters for each filter type. Rename the already existing fd_tcp_rule to fd_tcp4_filter_cnt to match the style of other names. To avoid style warnings, avoid assigning multiple parameters at once, and fix up one other case where we did so previously. Signed-off-by:

When flushing and replaying FDIR filters, it is possible we would disable ATR, and then re-enable it even though we should have kept it disabled due to existing TCP/IPv4 filters. Fix this by checking whether we have TCP4/IPv4 filters before re-enabling. Alternatively, we could instead restore ATR and then replay filters, however, this would cause us to rapidly enable and then disable ATR in some cases.

Move ATR exit check after we have sent the TCP/IPv4 filter to the ring successfully. This avoids an issue where we potentially update the filter count without actually succeeding in adding the filter. Now, we only increment the fd_tcp_rule after we've succeeded. Additionally, we will re-enable ATR mode only after deletion of the filter is actually posted to the FDIR ring. Change-ID: If5c1dea422081cc5e2de65618b01b4c3bf6bd586 Signed-off-by:

Instead of setting err=true and checking this to determine when to free the raw_packet near the end of the function, simply kfree and return immediately. The resulting code is a bit cleaner and has one less variable. This also resolves a subtle bug in the ipv4 case which could fail to add the first filter and then never free the memory, resulting in a small memory leak.

The code originally included src_ip and dst_ip with enough space to support ipv6 filters. However, no actual support for ipv6 filters has been implemented. Thus, remove the arrays and just use __be32 values. Should ipv6 support be added in the future, we can replace these with a union that has sizes for both values.

The firmware expects the port numbers for offloaded UDP tunnels in Little Endian format. We accidentally sent the value in Big Endian format which obviously will cause the wrong port number to be put into the UDP tunnels list. This results in VxLAN and Geneve tunnel Rx offloads being essentially disabled, unless the port number happens to be identical after byte swapping. Note that i40e_aq_add_udp_tunnel() will byteswap the parameter from host order into Little Endian so we don't need worry about passing strictly a __le16 value to the command. This patch essentially reverts b3f5c7bc ("i40e: Fix for extra byte swap in tunnel setup", 2016-08-24), but in a way that makes the result much more clear to the reader.

This reverts commit f9d40f6a ("igb: Revert support for build_skb in igb") and adds a few changes to update it to work with the latest version of igb. We are now able to revert the removal of this due to the fact that with the recent changes to the page count and the use of DMA_ATTR_SKIP_CPU_SYNC we can make the pages writable so we should not be invalidating the additional data added when we call build_skb.
