SMC currently uses the unsafe_global_rkey of the protection domain, which exposes all memory for remote reads and writes once a connection is established. This patch introduces separate memory regions with separate rkeys for every RMB. Now the unsafe_global_rkey of the protection domain is no longer needed. Signed-off-by:

The follow-on patch makes use of ib_map_mr_sg() when introducing separate memory regions for RMBs. This function is based on scatterlists; thus this patch introduces scatterlists for RMBs. Signed-off-by:

If a link group for a new server connection exists already, the mutex serializing the determination of link groups is given up early. The coming registration of memory regions benefits from the serialization as well, if the mutex is held till connection creation is finished. This patch postpones the unlocking of the link group creation mutex. Signed-off-by:

Since commit a390d1f3 ("phylib: convert state_queue work to delayed_work"), the PHYLIB state machine was converted to use delayed workqueues, yet some functions were still referencing the PHY library timer in their comments, fix that and remove the now unused linux/timer.h include. Signed-off-by:

Jakub Kicinski says: ==================== nfp: extend firmware request logic We have been pondering for some time how to support loading different application firmwares onto NFP. We want to support both users selecting one of the firmware images provided by Netronome (which are optimized for different use cases each) as well as firmware images created by users themselves or other companies. In the end we decided to go with the simplest solution - depending on the right firmware image being placed in /lib/firmware. This vastly simplifies driver logic and also doesn't require any new API. Different NICs on one system may want to run different applications therefore we first try to load firmware specific to the device (by serial number of PCI slot) and if not present try the device model based name we have been using so far. ==================== Signed-off-by: -

request_firmware() will fallback to user space helper and may cause long delays when driver is loaded if udev doesn't correctly handle FW requests. Since we never really made use of the user space helper functionality switch to the simpler request_firmware_direct() call. The side effect of this change is that no warning will be printed when the FW image does not exists. To help users figure out which FW file is missing print a info message when we request each file.

We generally look up firmware by card type, but that doesn't allow users who have more than one card of the same type in their system to select firmware per adapter. Unfortunately user space firmware helper seems fraught with difficulties and to be on its way out. In particular support for handling firmware uevents have been dropped from systemd and most distributions don't enable the FW fallback by default any more. To allow users selecting firmware for a particular device look up firmware names by serial and pci_name(). Use the direct lookup to disable generating uevents when enabled in Kconfig and not print any warnings to logs if adapter-specific files are missing. Users can place in /lib/firmware/netronome files named: pci-${pci_name}.nffw serial-${serial}.nffw to target a specific card. E.g.: pci-0000:04:00.0.nffw pci-0000:82:00.0.nffw serial-00-aa-bb-11-22-33-10-ff.nffw We use the full serial number including the interface id, as it appears in lspci output (bytes separated by '-').

We use a hack to defer probe when firmware was not pre-loaded or found on disk. This helps in case users forgot to include firmware in initramfs, the driver will most likely get another shot at probing after real root is mounted. This is not for what EPROBE_DEFER is supposed to be used, and when FW is completely missing every time new device is probed NFP will reprobe spamming kernel logs. Remove this hack, users will now have to make sure the right firmware image is present in initramfs if nfp.ko is placed there or built in. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-07-25 This series contains updates to i40e and i40evf only. Gustavo Silva fixes a variable assignment, where the incorrect variable was being used to store the error parameter. Carolyn provides a fix for a problem found in systems when entering S4 state, by ensuring that the misc vector's IRQ is disabled as well. Jake removes the single-threaded restriction on the module workqueue, which was causing issues with events such as CORER. Does some future proofing, by changing how the driver displays the UDP tunnel type. Paul adds a retry in releasing resources if the admin queue times out during the first attempt to release the resources. Jesse fixes up references to 32bit timspec, since there are a small set of errors on 32 bit, so we need to be using the right calls for dealing with timespec64 variables. Cleaned up code indentation and corrected an "if" conditional check, as well as making the code flow more clear. Cast or changed the types to remove warnings for comparing signed and unsigned types. Adds missing includes in i40evf, which were being used but were not being directly included. Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like other XDP enabled drivers, so that on dump we can retrieve the attached program based on the id and dump BPF insns, opcodes, etc back to user space. Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor fields, since they are in little-endian format. Also removed unnecessary "__packed" to a couple of i40evf structures. Stefan Assmann fixes an issue when an administratively set MAC was set and should now be switched back to 00:00:00:00:00:00, the pf_set_mac flag is not being toggled back to false. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-07-25 This series contains updates to ixgbe only. Tony provides all of the changes in the series, starting with adding a check to ensure that adding a MAC filter was successful, before setting the MACVLAN. In order to receive notifications of link configurations of the external PHY and support the configuration of the internal iXFI link on X552 devices, Tony enables LASI interrupts. Update the iXFI driver code flow, since the MAC register NW_MNG_IF_SEL fields have been redefined for X553 devices, so add MAC checks for iXFI flows. Added additional checks for flow control autonegotiation, since it is not support for X553 fiber and XFI devices. v2: removed unnecessary parens noticed by David Miller in patch 6 of the series. v3: dropped patch 6 of the original series, while we work out a more generic solution for malicious driver detection (MDD) support. v4: updated patch 1 of the series with the comments from Joe Perches which were: - switched logic to return on error - return 0 on success - declare retval as an integer ==================== Signed-off-by: -

The i40e driver attempts to display the UDP tunnel name by doing a check against the type, where for non-zero types we use "vxlan" and for zero type we use "geneve". This is not future proof, because if new tunnel types get added, we'll incorrectly label them. It also depends on the value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle. Instead, replace this with a function that can return a constant string depending on the type. For now we'll use "unknown" for types we don't know about, and we can expand this in the future if new types get added. Signed-off-by:

The compiler warned on an oddly indented bit of code, and when investigating that, noted that the functions themselves had an odd flow. The if condition was checked, and would exclude a call to AQ, but then the aq_ret would be checked unconditionally which just looks really weird, and is likely to cause objections. Signed-off-by:

During certain events such as a CORER, multiple devices will run a work task to handle some cleanup. This can cause issues due to a single-threaded workqueue which can mean that a device doesn't cleanup in time. Prevent this by removing the single-threaded restriction on the module workqueue. This avoids the need to add more complex yielding logic in our service task routine. This is also similar to what other drivers such as fm10k do. Signed-off-by:
