Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter updates for your net tree, they are: 1) Dump only conntrack that belong to this namespace via /proc file. This is some fallout from the conversion to single conntrack table for all netns, patch from Liping Zhang. 2) Missing MODULE_ALIAS_NF_LOGGER() for the ARP family that prevents module autoloading, also from Liping Zhang. 3) Report overquota event to the right netnamespace, again from Liping. 4) Fix tproxy listener sk refcount that leads to crash, from Eric Dumazet. 5) Fix racy refcounting on object deletion from nfnetlink and rule removal both for nfacct and cttimeout, from Liping Zhang. ==================== Signed-off-by: David S.

2016-08-18perf evsel: Do not access outside hw cache name arraysArnaldo Carvalho de Melo
We have to check if the values are >= *_MAX, not just >, fix it. From the bugzilla report: ''In file /tools/perf/util/evsel.c function __perf_evsel__hw_cache_name it appears that there is a bug that reads beyond the end of the buffer. The statement "if (type > PERF_COUNT_HW_CACHE_MAX)" allows type to be equal to the maximum value. Later, when statement "if (!perf_evsel__is_cache_op_valid(type, op))" is executed, the function can access array perf_evsel__hw_cache_stat[type] beyond the end of the buffer. It appears to me that the statement "if (type > PERF_COUNT_HW_CACHE_MAX)" should be "if (type >= PERF_COUNT_HW_CACHE_MAX)" Bug found with Coverity and manual code review. No attempts were made to execute the code with a maximum type value.''

2016-08-18i40e: fix lookup table when RSS disabled/enabledAlan Brady
This patch fixes the bug which causes RSS to continue to work after being disabled. After disabling RSS, traffic would continue to be assigned to different queues instead of falling back to a single queue. Without this patch, attempting to disable RSS would not work as expected. This patch fixes the bug by clearing the lookup table used by RSS such that all traffic is assigned to a single queue. This patch also addresses the issue of reinstating the lookup table should RSS then be re-enabled.

2016-08-18i40e: don't allow reduction of channels below active FD rulesJacob Keller
If a driver is unable to maintain all current user supplied settings from ethtool (or other sources), it is not ok for a user request to succeed and silently trample over previous configuration. To that end, if you change the number of channels, it must not be allowed to reduce the number of channels (queues) below the current flow director filter rules targets. In this case, return -EINVAL when a request to reduce the number of channels would do so. In addition log a warning to the kernel buffer explaining why we failed, and report the rules which prevent us from lowering the number of channels.

Without this patch, the driver will not pass the static analysis tool checks without generating warnings.

2016-08-18net/mlx5: Configure IB devices according to LAG stateAviv Heller
When mlx5_ib is loaded, we would like each card's IB devices to be added according to its LAG state (one IB device, instead of two, is to be added if LAG is active).

2016-08-18net/mlx5: Vport LAG creation supportAviv Heller
Add interfaces for issuing CREATE_VPORT_LAG and DESTROY_VPORT_LAG commands. Used for receiving PF1's eth traffic on PF0's root ft. Signed-off-by: Aviv Heller <avivh@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org>
2016-08-18net/mlx5: Add LAG flow steering namespaceAviv Heller
This namespace is used for LAG demux flowtable. The idea is to position the LAG demux ft between bypass and kernel flowtables, allowing raw-eth traffic from both ports to be received by the PF0 IB device.

2016-08-18net/mlx5: LAG demux flow table supportAviv Heller
Add interfaces to allow the creation and destruction of a LAG demux flow table. It is a special flow table used during LAG for redirecting non user-mode packets from PF0 to PF1 root ft, if a packet was received on phys port two.

2016-08-18net/mlx5: Get RoCE netdevAviv Heller
Used by IB driver for determining the IB bond device's netdev, when LAG is active. Returns PF0's netdev if mode is not active-backup, or the PF netdev of the active slave when mode is active-backup.

2016-08-18net/mlx5: Implement RoCE LAG featureAviv Heller
Available on dual port cards only, this feature keeps track, using netdev LAG events, of the bonding and link status of each port's PF netdev. When both of the card's PF netdevs are enslaved to the same bond/team master, and only them, LAG state is active. During LAG, only one IB device is present for both ports. In addition to the above, this commit includes FW commands used for managing the LAG, new facilities for adding and removing a single device by interface, and port remap functionality according to bond events. Please note that this feature is currently used only for mimicking Ethernet bonding for RoCE - netdevs functionality is not altered, and their bonding continues to be managed solely by bond/team driver.

2016-08-18net/mlx5: Add HW interfaces used by LAGAviv Heller
Exposed LAG commands enum and layouts: - CREATE_LAG HW enters LAG mode: RoCE traffic from port two is received on PF0 core dev. Allows to set tx_affinity (tx port) for QPs and TISes. Allows to port remap QPs and TISes, overriding their tx_affinity behavior. - MODIFY_LAG Remap QPs and TISes to another port. - QUERY_LAG Query whether LAG mode is active. - DESTROY_LAG HW exits LAG mode, returning to non-LAG behavior. - CREATE_VPORT_LAG Merge Ethernet flow steering, such that traffic received on port two jumps to PF0 root flow table. Available only in LAG mode. - DESTROY_VPORT_LAG Ethernet flow steering returns to non-LAG behavior. Caps added: - lag_master Driver is in charge of managing the LAG. This is currently the only option. - num_lag_ports LAG is supported only if this field's value is 2. Other fields: - QP/TIS tx port affinity During LAG, this field controls on which port a QP or TIS resides. - TIS strict tx affinity When this field is set, the TIS will not be subject to port remap by CREATE_LAG/MODIFY_LAG. - LAG demux flow table Flow table used for redirecting non user-space traffic back to PF1 root flow table, if the packet was received on port two.
