git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-06-04 This series contains a smorgasbord of updates to documentation, e1000e, igb, ixgbe, ixgbevf and i40e. Benjamin Poirier fixes a potential kernel crash due to NULL pointer dereference in e1000e. Jeff updates the kernel documentation for e100 and e1000 to correct default values and URLs which were incorrect in the documentation. Also took the time to update these to the new reStructured text format for kernel documentation. Joanna Yurdal fixes a missing PTP transmit timestamp by ensuring that TSICR gets cleared when ICR is cleared. Sergey updates igb to reset all the transmit queues at one time so that we only have to wait once for all the queues to be reset. Alex fixes ixgbevf so that malicious driver detection (MDD) can co-exist with XDP. Emil and Tony extend the RTNL lock to ensure we get the most up-to-date values for the bits and avoid a possible race condition when going down. YueHaibing from Huawei introduces a helper function in ixgbe for operation reads to simplify the code a bit more. Daniel Borkmann adds support for XDP meta data when using build SKB for i40e. Shannon Nelson provides twp fixes for the IPSec code in ixgbe, first is to make sure we do not try to offload the decryption of any incoming packet that is destined for the management engine. The other fix is to resolve a cast problem introduced by a sparse cleanup patch. ==================== Signed-off-by: David S. Miller <[email protected]>

Browsing thru the driver disassembly, I noticed that ARM gcc generated no code whatsoever for sh_eth_soft_swap() while building a little-endian kernel -- apparently __LITTLE_ENDIAN__ was not being #define'd, however it got implicitly #define'd when building with the SH gcc (I could only find the explicit #define __LITTLE_ENDIAN that was #include'd when building a little-endian kernel). Luckily, the Ether controller only doing big- endian DMA is encountered on the early SH771x SoCs only and all ARM SoCs implement EDMR.DE and thus set 'sh_eth_cpu_data::hw_swap'. But anyway, we need to fix the #ifdef inside sh_eth_soft_swap() to something that would work on all architectures...

2018-06-04mlxsw: spectrum_span: Suppress VLAN on BRIDGE_VLAN_INFO_UNTAGGEDPetr Machata1-1/+3
When offloading mirroring to gretap or ip6gretap netdevices, an 802.1q bridge is one of the soft devices permissible in the underlay when resolving the packet path. After the packet path is resolved to a particular bridge egress device, flags on packet VLAN determine whether the egressed packet should be tagged. The current logic however only ever sets the VLAN tag, never suppresses it. Thus if there's a VLAN netdevice above the bridge that determines the packet VLAN, that VLAN is never unset, and mirroring is configured with VLAN tagging. Fix by setting the packet VLAN on both branches: set to zero (for unset) when BRIDGE_VLAN_INFO_UNTAGGED, copy the resolved VLAN (e.g. from bridge PVID) otherwise.

2018-06-04ixgbevf: Fix coexistence of malicious driver detection with XDPAlexander Duyck2-7/+30
In the case of the VF driver it is supposed to provide a context descriptor that allows us to provide information about the header offsets inside of the frame. However in the case of XDP we don't really have any of that information since the data is minimally processed. As a result we were seeing malicious driver detection (MDD) events being triggered when the PF had that functionality enabled. To address this I have added a bit of new code that will "prime" the XDP ring by providing one context descriptor that assumes the minimal setup of an Ethernet frame which is an L2 header length of 14. With just that we can provide enough information to make the hardware happy so that we don't trigger MDD events.

2018-06-04igb: Clear TSICR interrupts together with ICRJoanna Yurdal1-0/+2
Issuing "ip link set up/down" can block TSICR interrupts, what results in missing PTP Tx timestamp and no PPS pulse generation. Problem happens when the link is set up with the TSICR interrupts pending. ICR is cleared before enabling interrupts, while TSICR is not. When all TSICR interrupts are pending at this moment, time_sync interrupt will never be generated. TSICR should be cleared as well. In order to reproduce the issue: 1. Setup linux with IEEE 1588 grandmaster and PPS output enabled 2. Continue setting link up/down with random intervals between commands 3. Wait until PPS is not generated ( only one pulse is generated and PPS dies), and ptp4l complains constantly about Tx timeout.

Commit 83129b37ef35 ("e1000e: fix systim issues", v4.2-rc1) reworked e1000e_get_base_timinca() in such a way that it can return -EINVAL for e1000_pch_spt if the SYSCFI bit is not set in TSYNCRXCTL. Some experimentation has shown that on I219 (e1000_pch_spt, "MAC: 12") adapters, the E1000_TSYNCRXCTL_SYSCFI flag is unstable; TSYNCRXCTL reads sometimes don't have the SYSCFI bit set. Retrying the read shortly after finds the bit to be set. This was observed at boot (probe) but also link up and link down. Moreover, the phc (PTP Hardware Clock) seems to operate normally even after reads where SYSCFI=0. Therefore, remove this register read and unconditionally set the clock parameters.

The API enables generic counters creation and define mapping to association with a verbs object, the current mlx5 driver is using this API for flow counters. With this API, an application can monitor the entire life cycle of object activity, defined here as a static counters attachment. This API also allows dynamic counters monitoring of measurement points for a partial period in the verbs object life cycle. In addition it presents the implementation of the generic counters interface. This will be achieved by extending flow creation by adding a new flow count specification type which allows the user to associate a previously created flow counters using the generic verbs counters interface to the created flow, once associated the user could read statistics by using the read function of the generic counters interface. The API includes: 1. create and destroyed API of a new counters objects 2. read the counters values from HW Note: Attaching API to allow application to define the measurement points per objects is a user space only API and this data is passed to kernel when the counted object (e.g. flow) is created with the counters object. =================== * tag 'verbs_flow_counters': IB/mlx5: Add counters read support IB/mlx5: Add flow counters read support IB/mlx5: Add flow counters binding support IB/mlx5: Add counters create and destroy support IB/uverbs: Add support for flow counters IB/core: Add support for flow counters IB/core: Support passing uhw for create_flow IB/uverbs: Add read counters support IB/core: Introduce counters read verb IB/uverbs: Add create/destroy counters support IB/core: Introduce counters object and its create/destroy IB/uverbs: Add an ib_uobject getter to ioctl() infrastructure net/mlx5: Export flow counter related API net/mlx5: Use flow counter pointer as input to the query function

When passed the XDP_XMIT_FLUSH flag i40e_xdp_xmit now performs the same kind of ring tail update as in i40e_xdp_flush. The advantage is that all the necessary checks have been performed and xdp_ring can be updated, instead of having to perform the exact same steps/checks in i40e_xdp_flush Signed-off-by: Jesper Dangaard Brouer <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]>
2018-06-03xdp: add flags argument to ndo_xdp_xmit APIJesper Dangaard Brouer5-6/+21
This patch only change the API and reject any use of flags. This is an intermediate step that allows us to implement the flush flag operation later, for each individual driver in a separate patch. The plan is to implement flush operation via XDP_XMIT_FLUSH flag and then remove XDP_XMIT_FLAGS_NONE when done.

2018-06-03mlx4_core: restore optimal ICM memory allocationEric Dumazet1-6/+12
Commit 1383cb8103bb ("mlx4_core: allocate ICM memory in page size chunks") brought two regressions caught in our regression suite. The big one is an additional cost of 256 bytes of overhead per 4096 bytes, or 6.25 % which is unacceptable since ICM can be pretty large. This comes from having to allocate one struct mlx4_icm_chunk (256 bytes) per MLX4_TABLE_CHUNK, which the buggy commit shrank to 4KB (instead of prior 256KB) Note that mlx4_alloc_icm() is already able to try high order allocations and fallback to low-order allocations under high memory pressure. Most of these allocations happen right after boot time, when we get plenty of non fragmented memory, there is really no point being so pessimistic and break huge pages into order-0 ones just for fun. We only have to tweak gfp_mask a bit, to help falling back faster, without risking OOM killings. Second regression is an KASAN fault, that will need further investigations.
