2016-02-17sctp: remove rcu_read_lock in sctp_seq_dump_remote_addrs()Xin Long
sctp_seq_dump_remote_addrs is only called by sctp_assocs_seq_show() and it has been protected by rcu_read_lock that is from rhashtable_walk_start(). So we will remove this one. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-02-17sctp: move rcu_read_lock from __sctp_lookup_association to ↵Xin Long
sctp_lookup_association __sctp_lookup_association() is only invoked by sctp_v4_err() and sctp_rcv(), both which run on the rx BH, and it has been protected by rcu_read_lock [see ip_local_deliver_finish() / ipv6_rcv()]. So we can move it to sctp_lookup_association, only let sctp_lookup_association use rcu_read_lock. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-17 This series contains updates to i40e/i40evf only. Jesse cleans up a duplicate declaration in probe. Then fixes a bug where the driver was using a offset based off a DMA handle while mapping and unmapping using sync_single_range_for_[cpu|device], when it should be using DMA handle (returned from alloc_coherent) and the offset of the memory to be sync'd. Fixed an issue where sync_vsi_filter() was allocating memory in a way that could sleep (GFP_KERNEL) which was causing a problem when called by the team driver under rcu_read_lock(). Shannon adds a check to ensure we do not attempt to do TSO when skb->ip_summed is not set to CHECKSUM_PARTIAL. Kiran add functions related to port mirroring features such as add/delete mirror rule. Jacob assigns the i40e_pf structure directly instead of using a large memcpy, to avoid a sparse warning and lets the compiler optimize the copy since it know the size of the structure in advance. Anjali enables GENEVE capability for XL710/X710 devices with firmware API version higher than 1.4.

2016-02-17amd-xgbe: Mask auto-negotiation interrupts in ISRLendacky, Thomas
Currently the auto-negotiation interrupt handling disables the irq instead of masking off the interrupts. This was done because the phy library was originally used to read and write the PCS registers, which could not be performed in interrupt context. Now that the phy library is no longer used to read and write the PCS registers the interrupts can be masked off in the interrupt service routine eliminating the need to call disable_irq/enable_irq. This also requires changing the protection mutex to a spinlock. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-02-17amd-xgbe: Do traffic class setup when called through dcbnlLendacky, Thomas
Currently the netdev traffic class setup is only performed when invoked through the ndo_setup_tc interface.

2016-02-17amd-xgbe: Fix the mapping of priorities to traffic classesLendacky, Thomas
The driver is checking the pfc_en field of the ieee_pfc structure to determine whether to associate a priority with a traffic class. This is incorrect since the pfc_en field is for determining if PFC is enabled for a traffic class. The association of priority to traffic class does not depend on whether the traffic class is enabled for PFC, so remove that check. Also, the mapping of priorities to traffic classes should be done when configuring the traffic classes and not the PFC support so move the priority to traffic class association from xgbe_config_dcb_pfc to xgbe_config_dcb_tc.

John Fastabend says: ==================== tc offload for cls_u32 on ixgbe This extends the setup_tc framework so it can support more than just the mqprio offload and push other classifiers and qdiscs into the hardware. The series here targets the u32 classifier and ixgbe driver. I worked out the u32 classifier because it is protocol oblivious and aligns with multiple hardware devices I have access to. I did an initial implementation on ixgbe because (a) I have one in my box (b) its a stable driver and (c) it is relatively simple compared to the other devices I have here but still has enough flexibility to exercise the features of cls_u32. I intentionally limited the scope of this series to the basic feature set. Specifically this uses a 'big hammer' feature bit to do the offload or not. If the bit is set you get offloaded rules if it is not then rules will not be offloaded. If we can agree on this patch series there are some more patches on my queue we can talk about to make the offload decision per rule using flags similar to how we do l2 mac updates. Additionally the error strategy can be improved to be hard aborting, log and continue, etc. I think these are nice to have improvements but shouldn't block this series. Also by adding get_parse_graph and set_parse_graph attributes as in my previous flow_api work we can build programmable devices and programmatically learn when rules can or can not be loaded into the hardware. Again future work. ... v3 includes a couple style fixups suggested by Jiri and a quick fix to ixgbe to check features flag and not dev_features flag the latter being always set. ==================== Signed-off-by: David S.

This adds initial support for offloading the u32 tc classifier. This initial implementation only implements a few base matches and actions to illustrate the use of the infrastructure patches. However it is an interesting subset because it handles the u32 next hdr logic to correctly map tcp packets from ip headers using the ihl and protocol fields. After this is accepted we can extend the match and action fields easily by updating the model header file. Also only the drop action is supported initially. Here is a short test script, #tc qdisc add dev eth4 ingress #tc filter add dev eth4 parent ffff: protocol ip \ u32 ht 800: order 1 \ match ip dst 15.0.0.1/32 match ip src 15.0.0.2/32 action drop <-- hardware has dst/src ip match rule installed --> #tc filter del dev eth4 parent ffff: prio 49152 #tc filter add dev eth4 parent ffff: protocol ip prio 99 \ handle 1: u32 divisor 1 #tc filter add dev eth4 protocol ip parent ffff: prio 99 \ u32 ht 800: order 1 link 1: \ offset at 0 mask 0f00 shift 6 plus 0 eat match ip protocol 6 ff #tc filter add dev eth4 parent ffff: protocol ip \ u32 ht 1: order 3 match tcp src 23 ffff action drop <-- hardware has tcp src port rule installed --> #tc qdisc del dev eth4 parent ffff: <-- hardware cleaned up --> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.

So its sort of a you get whatever your friendly vendor provides affair at the moment. In the future we can add the get routines and set routines to update this data structure.

2016-02-17i40e: add netdev info to VSI dumpShannon Nelson
Add a few more bits of netdev data into the debugfs output for dump VSI. For now, we'll add the features, hw_features, vlan_features, and flags bitflags and the state. More could be added later if needed. Also, tweak a couple nearby output lines for output readability.

2016-02-17i40evf: enable bus master after resetMitch Williams
If the VF is reset via VFLR, the device will be knocked out of bus master mode, and the driver will fail to recover from the reset. Fix this by enabling bus mastering after every reset. In a non-VFLR case, the bus master bit will not be disabled, and this call will have no effect.
