2018-03-11net: hns3: fix rx path skb->truesize reporting bugPeng Li
Original skb->truesize reports the received packet size, not the actual buffer size NIC driver allocated(1 Page). The linux net protocol will misjudge the true size of rx queue. Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-03-11macvlan: filter out unsupported feature flagsShannon Nelson
Adding a macvlan device on top of a lowerdev that supports the xfrm offloads fails with a new regression: # ip link add link ens1f0 mv0 type macvlan RTNETLINK answers: Operation not permitted Tracing down the failure shows that the macvlan device inherits the NETIF_F_HW_ESP and NETIF_F_HW_ESP_TX_CSUM feature flags from the lowerdev, but with no dev->xfrmdev_ops API filled in, it doesn't actually support xfrm. When the request is made to add the new macvlan device, the XFRM listener for NETDEV_REGISTER calls xfrm_api_check() which fails the new registration because dev->xfrmdev_ops is NULL. The macvlan creation succeeds when we filter out the ESP feature flags in macvlan_fix_features(), so let's filter them out like we're already filtering out ~NETIF_F_NETNS_LOCAL. When XFRM support is added in the future, we can add the flags into MACVLAN_FEATURES. This same problem could crop up in the future with any other new feature flags, so let's filter out any flags that aren't defined as supported in macvlan.

Pull rdma fixes from Doug Ledford: - Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging from bugs under load to bad error case handling - There in one largish patch fixing the locking in bnxt_re to avoid a machine hard lock situation - A few core bugs on error paths - A patch to reduce stack usage in the new CQ API - One mlx5 regression introduced in this merge window - There were new syzkaller scripts written for the RDMA subsystem and we are fixing issues found by the bot - One of the commits (aa0de36a40f4 “RDMA/mlx5: Fix integer overflow while resizing CQ”) is missing part of the commit log message and one of the SOB lines. The original patch was from Leon Romanovsky, and a cut-n-paste separator in the commit message confused patchworks which then put the end of message separator in the wrong place in the downloaded patch, and I didn’t notice in time. The patch made it into the official branch, and the only way to fix it in-place was to rebase. Given the pain that a rebase causes, and the fact that the patch has relevant tags for stable and syzkaller, a revert of the munged patch and a reapplication of the original patch with the log message intact was done. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (25 commits) RDMA/mlx5: Fix integer overflow while resizing CQ Revert "RDMA/mlx5: Fix integer overflow while resizing CQ" RDMA/ucma: Check that user doesn't overflow QP state RDMA/mlx5: Fix integer overflow while resizing CQ RDMA/ucma: Limit possible option size IB/core: Fix possible crash to access NULL netdev RDMA/bnxt_re: Avoid Hard lockup during error CQE processing RDMA/core: Reduce poll batch for direct cq polling IB/mlx5: Fix an error code in __mlx5_ib_modify_qp() IB/mlx5: When not in dual port RoCE mode, use provided port as native IB/mlx4: Include GID type when deleting GIDs from HW table under RoCE IB/mlx4: Fix corruption of RoCEv2 IPv4 GIDs RDMA/qedr: Fix iWARP write and send with immediate RDMA/qedr: Fix kernel panic when running fio over NFSoRDMA RDMA/qedr: Fix iWARP connect with port mapper RDMA/qedr: Fix ipv6 destination address resolution IB/core : Add null pointer check in addr_resolve RDMA/bnxt_re: Fix the ib_reg failure cleanup RDMA/bnxt_re: Fix incorrect DB offset calculation RDMA/bnxt_re: Unconditionly fence non wire memory operations ...

2018-03-09mlxsw: spectrum: Prevent duplicate mirrorsPetr Machata
The Spectrum ASIC doesn't support mirroring more than once from a single binding point (which is a port-direction pair). Therefore detect that a second binding of a given binding point is attempted. To that end, extend struct mlxsw_sp_span_inspected_port to track whether a given binding point is bound or not. Extend mlxsw_sp_span_entry_port_find() to look for ports based on the full unique key: port number, direction, and boundness. Besides fixing the overt bug where configured mirrors are not offloaded, this also fixes a more subtle bug: mlxsw_sp_span_inspected_port_del() just defers to mlxsw_sp_span_entry_bound_port_find(), and that used to find the first port with the right number (disregarding the type). Thus by adding and removing egress and ingress mirrors in the right order, one could trick the system into believing it has no egress mirrors when in fact it did have some. That then caused that mlxsw_sp_span_port_mtu_update() didn't update mirroring buffer when MTU was changed.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== mlx5-updates-2018-02-28-2 (IPSec-2) This series follows our previous one to lay out the foundations for IPSec in user-space and extend current kernel netdev IPSec support. As noted in our previous pull request cover letter "mlx5-updates-2018-02-28-1 (IPSec-1)", the IPSec mechanism will be supported through our flow steering mechanism. Therefore, we need to change the initialization order. Furthermore, IPsec is also supported in both egress and ingress. Since our current flow steering is egress only, we add an empty (only implemented through FPGA steering ops) egress namespace to handle that case. We also implement the required flow steering callbacks and logic in our FPGA driver. We extend the FPGA support for ESN and modifying a xfrm too. Therefore, we add support for some new FPGA command interface that supports them. The other required bits are added too. The new features and requirements are advertised via cap bits. Last but not least, we revise our driver's accel_esp API. This API will be shared between our netdev and IB driver, so we need to have all the required functionality from both worlds.

2018-03-08ibmvnic: Do not disable device during failover or partition migrationThomas Falcon
During a device failover or partition migration reset, it is not necessary to disable the backing adapter since it should not be running yet and its Command-Response Queue is closed.

2018-03-07net/mlx5: IPSec, Add support for ESNAviad Yehezkel
Currently ESN is not supported with IPSec device offload. This patch adds ESN support to IPsec device offload. Implementing new xfrm device operation to synchronize offloading device ESN with xfrm received SN. New QP command to update SA state at the following: ESN 1 ESN 2 ESN 3 |-----------*-----------|-----------*-----------|-----------* ^ ^ ^ ^ ^ ^ ^ - marks where QP command invoked to update the SA ESN state machine. | - marks the start of the ESN scope (0-2^32-1). At this point move SA ESN overlap bit to zero and increment ESN. * - marks the middle of the ESN scope (2^31). At this point move SA ESN overlap bit to one.

2018-03-07net/mlx5: Add flow-steering commands for FPGA IPSec implementationAviad Yehezkel
In order to add a context to the FPGA, we need to get both the software transform context (which includes the keys, etc) and the source/destination IPs (which are included in the steering rule). Therefore, we register new set of firmware like commands for the FPGA. Each time a rule is added, the steering core infrastructure calls the FPGA command layer. If the rule is intended for the FPGA, it combines the IPs information with the software transformation context and creates the respective hardware transform. Afterwards, it calls the standard steering command layer. Signed-off-by: Aviad Yehezkel <aviadye@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
