2017-04-21ibmvnic: Unmap longer term buffer before freeBrian King
Make sure we unregister long term buffers from the adapter prior to DMA unmapping it and freeing the buffer. Failure to do so could result in a DMA to a now invalid address.

2017-04-21ibmvnic: Fix ibmvnic_change_mac_addr struct formatMurilo Fossa Vicentini
The ibmvnic_change_mac_addr struct alignment was not matching the defined format in PAPR+, it had the reserved and return code fields swapped. As a consequence, the CHANGE_MAC_ADDR_RSP commands were being improperly handled and executed even when the operation wasn't successfully completed by the system firmware. Also changing the endianness of the debug message to make it easier to parse the CRQ content.

2017-04-21gso: Validate assumption of frag_list segementationIlan Tayari
Commit 07b26c9454a2 ("gso: Support partial splitting at the frag_list pointer") assumes that all SKBs in a frag_list (except maybe the last one) contain the same amount of GSO payload. This assumption is not always correct, resulting in the following warning message in the log: skb_segment: too many frags For example, mlx5 driver in Striding RQ mode creates some RX SKBs with one frag, and some with 2 frags. After GRO, the frag_list SKBs end up having different amounts of payload. If this frag_list SKB is then forwarded, the aforementioned assumption is violated. Validate the assumption, and fall back to software GSO if it not true.

For example, a very fast machine might tune this to 1000 microseconds, while my regression testing 486DX-25 needs it to be 4000 microseconds on a nearly idle network to prevent time_squeeze from being incremented.

This feature allows the administrator to set an fwmark for packets traversing a tunnel. This allows the use of independent routing tables for tunneled packets without the use of iptables. There is no concept of per-packet routing decisions through IPv4 tunnels, so this implementation does not need to work with per-packet route lookups as the v6 implementation may (with IP6_TNL_F_USE_ORIG_FWMARK). Further, since the v4 tunnel ioctls share datastructures (which can not be trivially modified) with the kernel's internal tunnel configuration structures, the mark attribute must be stored in the tunnel structure itself and passed as a parameter when creating or changing tunnel attributes.

This naming scheme does not work for platforms like MSM8660 which has I2S channels named CODEC_I2S_SPKR (rather than just "MI2S tertiary" and other repetitive names) and consequently have clocks named "codec-i2s-spkr-osr-clk" and similar.

2017-04-21spi: spi-ti-qspi: Use bounce buffer if read buffer is not DMA'bleVignesh R
Flash filesystems like JFFS2, UBIFS and MTD block layer can provide vmalloc'd or kmap'd buffers that cannot be mapped using dma_map_sg() and can potentially be in memory region above 32bit addressable region(ie buffers belonging to memory region backed by LPAE) of DMA, implement spi_flash_can_dma() interface to inform SPI core not to map such buffers. When buffers are not mapped for DMA, then use a pre allocated bounce buffer(64K = typical flash erase sector size) to read from flash and then do a copy to actual destination buffer. This is approach is much faster than using memcpy using CPU and also reduces CPU load. With this patch, UBIFS read speed is ~18MB/s and CPU utilization <20% on DRA74 Rev H EVM. Performance degradation is negligible when compared with non bounce buffer case while using UBIFS. Signed-off-by: Vignesh R <vigneshr@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-04-21IB/mlx5: Use IP version matching to classify IP trafficAriel Levkovich
This change adds the ability for flow steering to classify IPv4/6 packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP packets and hit IPv4/6 classifed steering rules. When user added a flow rule with IP classification, driver was implicitly adding ethertype matching to the created rule in order to distinguish between IPv4 and IPv6 protocols. Since IP packets with MPLS tag header have MPLS ethertype, they missed the rule and ended up hitting the default filters. Such behavior prevented from MPLS packets to undergo inbound traffic load balancing flows (if such were defined by configuring RSS) to achieve higher throughput - the way that non-MPLS IP packets performed. Since our device is able to look past the MPLS tag and identify the next protocol we introduce this solution which replaces Ethertype matching by the device's capability to perform IP version parsing and matching in order to distinguish between IPv4 and IPv6. Therefore, whenever a flow with IP spec is added and device support IP version matching, driver will implicitly add IP version matching to the rule (Based on the IP spec type) without Ethertype matching which will cause relevant MPLS tagged packets to hit this rule as well. Otherwise (device doesn't support IP version matching), we fall back to setting Ethertype matching. If the user's filters specify an L2 ethertype and an IP spec the rule will then match both the ethertype and the IP version. The device's support for IP version matching is reported by the device via dedicated capability bit in query_device_cap and named outer/inner_ip_version.

2017-04-21IB/mlx5: Add inner spec and IPv6 validation in user's flow attribute listAriel Levkovich
This change fixes an incomplete validation of the user's flow attributes list. Previous implementation validated only matching of IPv4 Ethertype to IPv4 spec of outer headers (in case both Ethernet with specified Ethertype and IP specs were present) and lacked the validation of: 1. Matching of IPv6 Ethertype in Ethernet spec (if such exists) to an IPv6 protocol spec (if such exists). 2. Validation of Ethertype to IP protocol matching on inner headers specs. Which could cause some combinations of unmatching Ethernet and IP protocols to pass validation and apply on the device. The fix adds validation of IPv6 Ethertype and IP spec as well as performing the scan on both outer and inner attributes.

2017-04-21IB/mlx5: Enlarge autogroup flow tableMaor Gottlieb
In order to enlarge the flow group size to 8k, we decrease the number of flow group types to 6 and increase the flow table size to 64k. Flow group size is calculated as follow: group_size = table_size / (#group_types + 1) Fixes: 038d2ef87572 ('IB/mlx5: Add flow steering support') Signed-off-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>
