As requested by Rob Herring on patch https://patchwork.ozlabs.org/patch/580862/. This is a new property that it's still in net-next and has never been used in production, so we are not breaking anything with the incompatible binding change. Signed-off-by:

Nikolay Aleksandrov says: ==================== bridge: mdb: add support for extended attributes This small set allows to extend the per mdb entry exported attributes, before this set we had only a structure exported which couldn't be changed because we would've broken user-space, after this we extend the attribute that was used for the structure and add per-mdb entry attributes after the struct has been added (see patch 02 for more details). Note that the reason we can't simply add an attribute after MDBA_MDB_ENTRY_INFO is that current users (e.g. iproute2) walk over the attribute list directly without checking for the attribute type. Patch 01 is a simple change to reduce one indentation level in order to avoid over 80 char lines. ==================== Signed-off-by: -

Currently mdb entries are exported directly as a structure inside MDBA_MDB_ENTRY_INFO attribute, we can't really extend it without breaking user-space. In order to export new mdb fields, I've converted the MDBA_MDB_ENTRY_INFO into a nested attribute which starts like before with struct br_mdb_entry (without header, as it's casted directly in iproute2) and continues with MDBA_MDB_EATTR_ attributes. This way we keep compatibility with older users and can export new data. I've tested this with iproute2, both with and without support for the added attribute and it works fine. So basically we again have MDBA_MDB_ENTRY_INFO with struct br_mdb_entry inside but it may contain also some additional MDBA_MDB_EATTR_ attributes such as MDBA_MDB_EATTR_TIMER which can be parsed by user-space. So the new structure is: [MDBA_MDB] = { [MDBA_MDB_ENTRY] = { [MDBA_MDB_ENTRY_INFO] [MDBA_MDB_ENTRY_INFO] { <- Nested attribute struct br_mdb_entry <- nla_put_nohdr() [MDBA_MDB_ENTRY attributes] <- normal netlink attributes } } } Signed-off-by:Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-19 This series contains updates to i40e/i40evf only. Alex Duyck splits up the descriptor count function from the function that stops the ring to have access to the descriptor count used for the data portion of the frame. The rewrites the logic for how we determine if we can transmit the frame or if it needs to be linearized. Place the checksum close to TSO since they have a lot in common and it can help to reduce the decision tree for how to handle the frame as the first check in TSO is to see if checksumming is offloaded. Carolyn adds functions to blink leds on devices using 10GBaseT PHY since MAC registers used in other designs do not work in this device configuration. Fixes an issue where a previously removed message has returned. Kevin increases the timeout when checking GLGEN_RSTAT_DEVSTATE bit since linking with particular PHY types, the amount of time it takes for the GLGEN_RSTAT_DEVSTATE to be set increases greatly. Neerav changes the receive queues to not wait to be disabled before DCB has been reconfigured, like transmit queues. Anjali adds new register definitions for programming the parser, flow director and RSS blocks in the hardware. Shannon adds the new opcodes and structures used for asking the firmware to update receive control registers that need extra care when being accessed while under heavy traffic. Integrates the new AdminQ functions for safely accessing the receive control registers that may be affected by heavy small packet traffic.

On all of the other Intel drivers we place checksum close to TSO as they have a significant amount in common and it can help to reduce the decision tree for how to handle the frame as the first check in TSO is to see if checksumming is offloaded, and if it is not we can skip _BOTH_ TSO and Tx checksum offload based on a single check.

This patch is meant to rewrite the logic for how we determine if we can transmit the frame or if it needs to be linearized. The previous code for this function was using a mix of division and modulus division as a part of computing if we need to take the slow path. Instead I have replaced this by simply working with a sliding window which will tell us if the frame would be capable of causing a single packet to span several descriptors. The logic for the scan is fairly simple. If any given group of 6 fragments is less than gso_size - 1 then it is possible for us to have one byte coming out of the first fragment, 6 fragments, and one or more bytes coming out of the last fragment. This gives us a total of 8 fragments which exceeds what we can allow so we send such frames to be linearized. Arguably the use of modulus might be more exact as the approach I propose may generate some false positives. However the likelihood of us taking much of a hit for those false positives is fairly low, and I would rather not add more overhead in the case where we are receiving a frame composed of 4K pages.

In an upcoming patch I would like to have access to the descriptor count used for the data portion of the frame. For this reason I am splitting up the descriptor count function from the function that stops the ring. Also in order to try and reduce unnecessary duplication of code I am moving the slow-path portions of the code out of being inline calls so that we can just jump to them and process them instead of having to build them into each function that calls them.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-18 This series contains updates to i40e and i40evf only. Alex Duyck provides all the patches in the series to update and fix the drivers. Fixed the driver to drop the outer checksum offload on UDP tunnels, since the issue is that the upper levels of the stack never requested such an offload and it results in possible errors. Updates the TSO function to just use u64 values, so we do not have to end up casting u32 values. In the TSO path, factored out the L4 header offsets allowing us to ignore the L4 header offsets when dealing with the L3 checksum and length update. Consolidates all of the spots where we were updating either the TCP or IP checksums in the TSO and checksum path into the TSO function. Fixed two issues by adding support for IPv4 encapsulated in IPv6, first issue was the fact that iphdr(skb)->protocol was being used to test for the outer transport protocol which breaks IPv6 support. The second was that we cleared the flag for v4 going to v6, but we did not take care of txflags going the other way. Added support for IPv6 extension headers in setting up the Tx checksum. Added exception handling to the Tx checksum path so that we can handle cases of TSO where the frame is bad, or Tx checksum where we did not recognize a protocol. Fixed a number of issues to make certain that we are using the correct protocols when parsing both the inner and outer headers of a frame that is mixed between IPv4 and IPv6 for inner and outer. Updated the feature flags to reflect the newly enabled/added features. Sorry, no witty patch descriptions this time around, probably should let Mitch help in writing patch descriptions for Alex. :-) ==================== Signed-off-by: -

Recent changes should have enabled support for IPv6 based tunnels and support for TSO with outer UDP checksums. As such we can update the feature flags to reflect that. In addition we can clean-up the flags that aren't needed such as SCTP and RXCSUM since having the bits there doesn't add any value. I also found one spot where we were setting the same flag twice. It looks like it was probably a git merge error that resulted in the line being duplicated. As such I have dropped it in this patch. Signed-off-by:

All of the documentation in the datasheets for the XL710 do not call out any reason to exclude support for IPv6 based tunnels. As such I am dropping the code that was excluding these tunnel types from having their port numbers recognized. This way we can take advantage of things such as checksum offload for inner headers over IPv6 based VXLAN or GENEVE tunnels. Signed-off-by:

This patch takes advantage of several assumptions we can make about the headers of the frame in order to reduce overall processing overhead for computing the outer header checksum. First we can assume the entire header is in the region pointed to by skb->head as this is what csum_start is based on. Second, as a result of our first assumption, we can just call csum_partial instead of making a call to skb_checksum which would end up having to configure things so that we could walk through the frags list.

Jiri Benc says: ==================== iptunnel: scrub packet in iptunnel_pull_header As every IP tunnel has to scrub skb on decapsulation, iptunnel_pull_header tried to do that and open coded part of skb_scrub_packet. Various tunneling protocols (VXLAN, Geneve) then called full skb_scrub_packet on their own, duplicating part of the scrubbing already done. Consolidate the code, calling skb_scrub_packet from iptunnel_pull_header. This will allow additional cleanups in VXLAN code, as the packet is scrubbed early during rx processing after this patchset and VXLAN can start filling out skb fields earlier.
