When removing all configured macs on a 578xx adapter, if a positive value would be returned driver would errneously log it as an error.

2017-06-10bnx2x: Don't post statistics to malicious VFsMintz, Yuval2-1/+13
Once firmware indicates that a given VF is malicious and until that VF passes an FLR all bets are off - PF can't know anything is happening to the VF [since VF can't communicate anything to its PF]. But PF is currently still periodically asking device to collect statistics for the VF which might in turn fill logs by IOMMU blocking memory access done by the VF's PCI function [in the case VF has unmapped its buffers].

VF clients are configured as enforced, meaning firmware is validating the correctness of their ethertype/vid during transmission. Once txvlan is disabled, VF would start getting SKBs for transmission here vlan is on the payload - but it'll pass the packet's ethertype instead of the vid, leading to firmware declaring it as malicious.

We need to push the chain index down to the drivers, so they have the information to which chain the rule belongs. For now, no driver supports multichain offload, so only chain 0 is supported.

2017-06-01bnx2x: Fix Multi-CosMintz, Yuval1-1/+1
Apparently multi-cos isn't working for bnx2x quite some time - driver implements ndo_select_queue() to allow queue-selection for FCoE, but the regular L2 flow would cause it to modulo the fallback's result by the number of queues. The fallback would return a queue matching the needed tc [via __skb_tx_hash()], but since the modulo is by the number of TSS queues where number of TCs is not accounted, transmission would always be done by a queue configured into using TC0.

2017-05-01bnx2x: Align RX buffersScott Wood1-0/+1
The bnx2x driver is not providing proper alignment on the receive buffers it passes to build_skb(), causing skb_shared_info to be misaligned. skb_shared_info contains an atomic, and while PPC normally supports unaligned accesses, it does not support unaligned atomics. Aligning the size of rx buffers will ensure that page_frag_alloc() returns aligned addresses. This can be reproduced on PPC by setting the network MTU to 1450 (or other non-multiple-of-4) and then generating sufficient inbound network traffic (one or two large "wget"s usually does it), producing the following oops: Unable to handle kernel paging request for unaligned access at address 0xc00000ffc43af656 Faulting instruction address: 0xc00000000080ef8c Oops: Kernel access of bad area, sig: 7 [#1] SMP NR_CPUS=2048 NUMA PowerNV Modules linked in: vmx_crypto powernv_rng rng_core powernv_op_panel leds_powernv led_class nfsd ip_tables x_tables autofs4 xfs lpfc bnx2x mdio libcrc32c crc_t10dif crct10dif_generic crct10dif_common CPU: 104 PID: 0 Comm: swapper/104 Not tainted 4.11.0-rc8-00088-g4c761da #2 task: c00000ffd4892400 task.stack: c00000ffd4920000 NIP: c00000000080ef8c LR: c00000000080eee8 CTR: c0000000001f8320 REGS: c00000ffffc33710 TRAP: 0600 Not tainted (4.11.0-rc8-00088-g4c761da) MSR: 9000000000009033 <SF,HV,EE,ME,IR,DR,RI,LE> CR: 24082042 XER: 00000000 CFAR: c00000000080eea0 DAR: c00000ffc43af656 DSISR: 00000000 SOFTE: 1 GPR00: c000000000907f64 c00000ffffc33990 c000000000dd3b00 c00000ffcaf22100 GPR04: c00000ffcaf22e00 0000000000000000 0000000000000000 0000000000000000 GPR08: 0000000000b80008 c00000ffc43af636 c00000ffc43af656 0000000000000000 GPR12: c0000000001f6f00 c00000000fe1a000 000000000000049f 000000000000c51f GPR16: 00000000ffffef33 0000000000000000 0000000000008a43 0000000000000001 GPR20: c00000ffc58a90c0 0000000000000000 000000000000dd86 0000000000000000 GPR24: c000007fd0ed10c0 00000000ffffffff 0000000000000158 000000000000014a GPR28: c00000ffc43af010 c00000ffc9144000 c00000ffcaf22e00 c00000ffcaf22100 NIP [c00000000080ef8c] __skb_clone+0xdc/0x140 LR [c00000000080eee8] __skb_clone+0x38/0x140 Call Trace: [c00000ffffc33990] [c00000000080fb74] skb_clone+0x74/0x110 (unreliable) [c00000ffffc339c0] [c000000000907f64] packet_rcv+0x144/0x510 [c00000ffffc33a40] [c000000000827b64] __netif_receive_skb_core+0x5b4/0xd80 [c00000ffffc33b00] [c00000000082b2bc] netif_receive_skb_internal+0x2c/0xc0 [c00000ffffc33b40] [c00000000082c49c] napi_gro_receive+0x11c/0x260 [c00000ffffc33b80] [d000000066483d68] bnx2x_poll+0xcf8/0x17b0 [bnx2x] [c00000ffffc33d00] [c00000000082babc] net_rx_action+0x31c/0x480 [c00000ffffc33e10] [c0000000000d5a44] __do_softirq+0x164/0x3d0 [c00000ffffc33f00] [c0000000000d60a8] irq_exit+0x108/0x120 [c00000ffffc33f20] [c000000000015b98] __do_irq+0x98/0x200 [c00000ffffc33f90] [c000000000027f14] call_do_irq+0x14/0x24 [c00000ffd4923a90] [c000000000015d94] do_IRQ+0x94/0x110 [c00000ffd4923ae0] [c000000000008d90] hardware_interrupt_common+0x150/0x160 Signed-off-by: David S.

2017-03-16mqprio: Modify mqprio to pass user parameters via ndo_setup_tc.Amritha Nambiar1-1/+4
The configurable priority to traffic class mapping and the user specified queue ranges are used to configure the traffic class, overriding the hardware defaults when the 'hw' option is set to 0. However, when the 'hw' option is non-zero, the hardware QOS defaults are used. This patch makes it so that we can pass the data the user provided to ndo_setup_tc. This allows us to pull in the queue configuration if the user requested it as well as any additional hardware offload type requested by using a value other than 1 for the hw value. Finally it also provides a means for the device driver to return the level supported for the offload type via the qopt->hw value. Previously we were just always assuming the value to be 1, in the future values beyond just 1 may be supported.

2016-12-05bnx2x: Correct ringparam estimate when DOWNMintz, Yuval1-0/+8
Until interface is up [and assuming ringparams weren't explicitly configured] when queried for the size of its rings bnx2x would claim they're the maximal size by default. That is incorrect as by default the maximal number of buffers would be equally divided between the various rx rings. This prevents the user from actually setting the number of elements on each rx ring to be of maximal size prior to transitioning the interface into up state. To fix this, make a rough estimation about the number of buffers. It wouldn't always be accurate, but it would be much better than current estimation and would allow users to increase number of buffers during early initialization of the interface.

Mostly simple overlapping changes. For example, David Ahern's adjacency list revamp in 'net-next' conflicted with an adjacency list traversal bug fix in 'net'. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-10-24bnx2x: Use the correct divisor value for PHC clock readings.Sudarsana Reddy Kalluru1-1/+1
Time Sync (PTP) implementation uses the divisor/shift value for converting the clock ticks to nanoseconds. Driver currently defines shift value as 1, this results in the nanoseconds value to be calculated as half the actual value. Hence the user application fails to synchronize the device clock value with the PTP master device clock. Need to use the 'shift' value of 0.

2016-09-26bnx2x: allocate mac filtering pending list in PAGE_SIZE incrementsJason Baron1-37/+86
Currently, we can have high order page allocations that specify GFP_ATOMIC when configuring multicast MAC address filters. For example, we have seen order 2 page allocation failures with ~500 multicast addresses configured. Convert the allocation for the pending list to be done in PAGE_SIZE increments.

2016-09-24net: Update API for VF vlan protocol 802.1ad supportMoshe Shemesh2-3/+9
Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.
