2018-07-12net: mvpp2: make sure we don't spread load on disabled CPUsMaxime Chevallier
When filling the RSS table, we have to make sure that the rx queue is attached to an online CPU. This patch is not a full support for cpu_hotplug, but rather a way to make sure that we don't break network on system booted with the maxcpus parameter.

2018-07-12net: mvpp2: improve the distribution of packets on CPUs when using RSSAntoine Tenart
This patch adds an extra indirection when setting the indirection table into the RSS hardware table to improve the packets distribution across CPUs. For example, if 2 queues are used on a multi-core system this new indirection will choose two queues on two different CPUs instead of the two first queues which are on the same first CPU.

2018-07-12net: mvpp2: use one RSS table per portMaxime Chevallier
PPv2 Controller has 8 RSS Tables, of 32 entries each. A lookup in the RXQ2RSS_TABLE is performed for each incoming packet, and the RSS Table to be used is chosen according to the default rx queue that would be used for the packet. This default rx queue is set in the Lookup_id Table (also called Decoding Table), and is equal to the port->first_rxq. Since the Classifier itself isn't active at any time for the moment, this doesn't have a direct effect, the default rx queue at the moment is the one where all packets end-up into.

2018-07-12net: mvpp2: fix RSS register definitionsMaxime Chevallier
There is no RSS_TABLE register in PPv2 Controller. The register 0x1510 which was specified is actually named "RSS_HASH_SEL", but isn't used by this driver at all. Based on how this register was used, it should have been the RXQ2RSS_TABLE register, which allows to select the RSS table that will be used for the incoming packet. The RSS_TABLE_POINTER is actually a field of this RXQ2RSS_TABLE register. Since RSS tables are actually not used by the driver for now, this commit does not fix a runtime bug.

When offloading mirror-to-gretap, mlxsw needs to preroute the path that the encapsulated packet will take. That path may include a LAG device above a front panel port. So far, mlxsw resolved the path to the first up front panel slave of the LAG interface, but that only reflects administrative state of the port. It neglects to consider whether the port actually has a carrier, and what the LACP state is. So instead of checking upness of the device, check carrier state and txability.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== L2 Fwd Offload & 10GbE Intel Driver Updates 2018-07-09 This patch series is meant to allow support for the L2 forward offload, aka MACVLAN offload without the need for using ndo_select_queue. The existing solution currently requires that we use ndo_select_queue in the transmit path if we want to associate specific Tx queues with a given MACVLAN interface. In order to get away from this we need to repurpose the tc_to_txq array and XPS pointer for the MACVLAN interface and use those as a means of accessing the queues on the lower device. As a result we cannot offload a device that is configured as multiqueue, however it doesn't really make sense to configure a macvlan interfaced as being multiqueue anyway since it doesn't really have a qdisc of its own in the first place. The big changes in this set are: Allow lower device to update tc_to_txq and XPS map of offloaded MACVLAN Disable XPS for single queue devices Replace accel_priv with sb_dev in ndo_select_queue Add sb_dev parameter to fallback function for ndo_select_queue Consolidated ndo_select_queue functions that appeared to be duplicates ==================== Signed-off-by: David S.

2018-07-11net/mlx5: fix uaccess beyond "count" in debugfs read/write handlersJann Horn
In general, accessing userspace memory beyond the length of the supplied buffer in VFS read/write handlers can lead to both kernel memory corruption (via kernel_read()/kernel_write(), which can e.g. be triggered via sys_splice()) and privilege escalation inside userspace. In this case, the affected files are in debugfs (and should therefore only be accessible to root) and check that *pos is zero (which prevents the sys_splice() trick). Therefore, this is not a security fix, but rather a small cleanup. For the read handlers, fix it by using simple_read_from_buffer() instead of custom logic.

The max IRQ count is checked when re-initializing the IRQ vectors and this can happen multiple times during ifup or ethtool -L. If the max IRQ is reduced and the RDMA driver is operational, we may not initailize IRQs correctly. This problem shows up on VFs with very small number of MSIX.
