A recent change to the dst_output handling caused a new warning when the call to NF_HOOK() is the only used of a local variable passed as 'dev', and CONFIG_NETFILTER is disabled: net/ipv6/ip6_output.c: In function 'ip6_output': net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' [-Wunused-variable] The reason for this is that the NF_HOOK macro in this case does not reference the variable at all, and the call to dev_net(dev) got removed from the ip6_output function. To avoid that warning now and in the future, this changes the macro into an equivalent inline function, which tells the compiler that the variable is passed correctly but still unused. The dn_forward function apparently had the same problem in the past and added a local workaround that no longer works with the inline function. In order to avoid a regression, we have to also remove the #ifdef from decnet in the same patch. Fixes: ede2059d ("dst: Pass net into dst->output") Signed-off-by:

since commit 8405a8ff ("netfilter: nf_qeueue: Drop queue entries on nf_unregister_hook") all pending queued entries are discarded. So we can simply remove all of the owner handling -- when module is removed it also needs to unregister all its hooks. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Driver update, add initial support for Spectrum ASIC Purpose of this patchset is to introduce initial support for Mellanox Spectrum ASIC, including L2 bridge forwarding offload. The only non-mlxsw patch in this patchset is the first one, introducing pre-change upper notifier. That is used in last patch to ensure ports of single ASIC are not bridged into multiple bridges, as that scenario is currently not supported by driver. ==================== Signed-off-by:David S.

Packets destined to offloaded netdevs will be classified to FIDs in the device and flooded in case of BUM. The flooding table used is of type FID-offset, which allows one to create different flooding domains for different FIDs and specify the offset in the flooding table for each FID (not necessarily equal to FID or VID). Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size. Signed-off-by:

In the newly introduced Spectrum switch ASIC, packets destined to not offloaded netdevs will be classified to special FIDs (vFIDs) in the device and flooded to the CPU port. The flooding table used is of type per-FID, which allows one to create different flooding domains for different vFIDs. While using a simple single-entry flood table is certainly sufficient at this point, we do plan to offload 802.1D bridges involving VLAN interfaces, thus making this change necessary.

This newly introduced netdevice notifier is called before actual change upper happens. That provides a possibility for notifier handlers to know upper change will happen and react to it, including possibility to forbid the change. That is valuable for drivers which can check if the upper device linkage is supported and forbid that in case it is not. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-16 This series contains updates to e1000, e1000e, igb, igbvf, ixgbe, ixgbevf, i40e, i40evf and fm10k. Alex Duyck fixes the polling routine for i40e/i40evf were the NAPI budget for receive cleanup was being rounded up to 1 but the netpoll call was expecting no Rx to be processed as the budget passed was 0. Also cleaned up IN_NETPOLL flag that was not adding any value due to the receive cleanup was handled in NAPI. Added support for netpoll for i40evf as well. Jesse updates all of our drivers to use napi_complete_done() instead of napi_complete(), which allows us to use /sys/class/net/ethX/gro_flush_timeout. Added ethtool support to control and report the new Interrupt Limit register, since the XL710 hardware has a different interrupt moderation design that can support a limit of total interrupts per second per vector. Shannon cleans up startup log entries to cut down the number by putting a couple behind debug flags and combining others into single line. Added support to enable/disable printing VEB statistics via ethtool. Jingjing fixes a compile issue by adding const to functions that return strings that are not going to be modified. Greg Rose cleans up defines that were not used and were causing customer confusion. Greg Bowers adds support for setting a new bit in the Set Local LLDP MIB admin queue command Type field. Mitch fixes an issue where vlan_features field was set to the same value as netdev features field, but before the features were actually being set up, leaving the vlan_features empty. Resolve the issue by setting up the netdev features first, then mask out the VLAN feature bits when assigning vlan_features. Fixed VF init timing, where in some instances the VFs would fail to initialize the first time you loaded the driver. To correct this, increased the delay time for the init task and wait longer before giving up. v2: fix missing space in function header comment in patch 3, based on feedback from Sergei Shtylyov. ==================== Signed-off-by: -

With 64 VFs, we can easily overwhelm the AQ on the PF if we have too low a limit on the number of AQ requests. This leads to ARQ overflow errors, and occasionally VFs that fail to initialize. Since we really only hit this condition on initial VF driver load, the requests that we process are lightweight, so this extra work doesn't cause problems for the PF driver.

On some devices, in some systems, in some configurations, the VFs would fail to initialize the first time you loaded the driver. To correct this, increase the delay time for the init task slightly, and wait longer before giving up. If we enable VFs and load the VF driver in the same kernel as the PF driver, we can totally overwhelm the PF driver with AQ requests because all of the instances try to initialize at the same time. To help alleviate this, stagger the initial scheduling of the init task using the PCIe function as a multiplier. We mask off the function to only three bits so no instance has to wait too long. With these two changes, initializing 128 VFs on a single device goes from four minutes to just a few seconds. Change-ID: If3d8720c1c4e838ab36d8781d9ec295a62380936 Signed-off-by:

The vlan_features field was correctly being set to the same value as the netdev features field. However, this was being done before the features were actually being set up, leaving the vlan_features empty. Also, after a reset, vlan_features will be incorrectly assigned the previous netdev feature flags, which can contain VLAN feature bits. This makes the VLAN code angry and will cause a stack dump. To fix these issues, set up the netdev features first, then mask out the VLAN feature bits when assigning vlan_features. Change-ID: Ib0548869dc83cf6a841cb8697dd94c12359ba4d2 Signed-off-by:

When the number of invalid messages from a VF is exceeded, the VF will be disabled, due to the invalid messages. This happens if other VF drivers (like DPDK) send a message through the driver's mailbox (aka virtchannel) interface, but the message is not supported by the i40e pf driver, such as CONFIG_PROMISCUOUS_MODE. This patch changes the num_invalid_msgs in struct i40e_vf to record the continuous invalid msgs, and it will be reset when a valid msg is received.

The XL710 hardware has a different interrupt moderation design that can support a limit of total interrupts per second per vector, in addition to the "number of interrupts per second" controls already established in the driver. This combination of hardware features allows us to set very low default latency settings but minimize the total CPU utilization by not making too many interrupts, should the user desire. The current driver implementation is still enabling the dynamic moderation in the driver, and only using the rx/tx-usecs limit in ethtool to limit the interrupt rate per second, by default. The new code implemented in this patch 2) adds init/use of the new "Interrupt Limit" register 3) adds ethtool knob to control/report the limits above Usage is ethtool -C ethx rx-usecs-high <value> Where <value> is number of microseconds to create a rate of 1/N interrupts per second, regardless of rx-usecs or tx-usecs values. Since there is a credit based scheme in the hardware, the rx-usecs and tx-usecs can be configured for very low latency for short bursts, but once the credit runs out the refill rate on the credits is limited by rx-usecs-high.

Allow the nvmupdate application to decide when a read or write error should be exposed to the user. Since the application needs to use write probes to find the ReadOnly sections on a potentially unknown NVM version in the HW and read probes to check the status of the last write, some error messages are expected, but need not be shown to the users. The driver doesn't know which are ignorable from real errors, so needs to let the application make the decision. Change-ID: I78fca8ab672bede11c10c820b83c26adfd536d03 Signed-off-by:
