<title>vdpa/mlx5: Fix mlx5_vdpa_get_config() endianness on big-endian machines</title>

[ Upstream commit 439252e167ac45a5d46f573aac1da7d8f3e051ad ]

mlx5_vdpa_dev_add() doesn’t initialize mvdev-&gt;actual_features. It’s
initialized later by mlx5_vdpa_set_driver_features(). However,
mlx5_vdpa_get_config() depends on the VIRTIO_F_VERSION_1 flag in
actual_features, to return data with correct endianness. When it’s called
before mlx5_vdpa_set_driver_features(), the data are incorrectly returned
as big-endian on big-endian machines, while QEMU then interprets them as
little-endian.

The fix is to initialize this VIRTIO_F_VERSION_1 as early as possible,
especially considering that mlx5_vdpa_dev_add() insists on this flag to
always be set anyway.

commit a6097e0a54a5c24f8d577ffecbc35289ae281c2e upstream.

create_user_mr() has correct code to count the number of null keys
used to fill in a hole for the memory map. However, fill_indir()
does not follow the same to cap the range up to the 1GB limit
correspondingly. Fill in more null keys for the gaps in between,
so that null keys are correctly populated.

Updated the driver to utilize all the MSI-X interrupt vectors supported
by each OCTEON endpoint VF, instead of relying on a single vector.
Enabling more interrupts allows packets from multiple rings to be
distributed across multiple cores, improving parallelism and
performance.

Pull networking updates from Paolo Abeni:
 "This is slightly smaller than usual, with the most interesting work
  being still around RTNL scope reduction.

  Core:

   - More core refactoring to reduce the RTNL lock contention, including
     preparatory work for the per-network namespace RTNL lock, replacing
     RTNL lock with a per device-one to protect NAPI-related net device
     data and moving synchronize_net() calls outside such lock.

   - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
     and more specific TCP coverage.

   - Reduce network namespace tear-down time by removing per-subsystems
     synchronize_net() in tipc and sched.

   - Add flow label selector support for fib rules, allowing traffic
     redirection based on such header field.

  Netfilter:

   - Do not remove netdev basechain when last device is gone, allowing
     netdev basechains without devices.

   - Revisit the flowtable teardown strategy, dealing better with fin,
     reset and re-open events.

   - Scale-up IP-vs connection dumping by avoiding linear search on each
     restart.

  Protocols:

   - A significant XDP socket refactor, consolidating and optimizing
     several helpers into the core

   - Better scaling of ICMP rate-limiting, by removing false-sharing in
     inet peers handling.

   - Introduces netlink notifications for multicast IPv4 and IPv6
     address changes.

   - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
     aggregation and fragmentation of the inner IP.

   - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
     avoid local port exhaustion issues when the average connection
     lifetime is very short.

   - Support updating keys (re-keying) for connections using kernel TLS
     (for TLS 1.3 only).

   - Support ipv4-mapped ipv6 address clients in smc-r v2.

   - Add support for jumbo data packet transmission in RxRPC sockets,
     gluing multiple data packets in a single UDP packet.

   - Support RxRPC RACK-TLP to manage packet loss and retransmission in
     conjunction with the congestion control algorithm.

  Driver API:

   - Introduce a unified and structured interface for reporting PHY
     statistics, exposing consistent data across different H/W via
     ethtool.

   - Make timestamping selectable, allow the user to select the desired
     hwtstamp provider (PHY or MAC) administratively.

   - Add support for configuring a header-data-split threshold (HDS)
     value via ethtool, to deal with partial or buggy H/W
     implementation.

   - Consolidate DSA drivers Energy Efficiency Ethernet support.

   - Add EEE management to phylink, making use of the phylib
     implementation.

   - Add phylib support for in-band capabilities negotiation.

   - Simplify how phylib-enabled mac drivers expose the supported
     interfaces.

  Tests and tooling:

   - Make the YNL tool package-friendly to make it easier to deploy it
     separately from the kernel.

   - Increase TCP selftest coverage importing several packetdrill
     test-cases.

   - Regenerate the ethtool uapi header from the YNL spec, to ease
     maintenance and future development.

   - Add YNL support for decoding the link types used in net self-tests,
     allowing a single build to run both net and drivers/net.

  Drivers:

   - Ethernet high-speed NICs:
      - nVidia/Mellanox (mlx5):
         - add cross E-Switch QoS support
         - add SW Steering support for ConnectX-8
         - implement support for HW-Managed Flow Steering, improving the
           rule deletion/insertion rate
         - support for multi-host LAG
      - Intel (ixgbe, ice, igb):
         - ice: add support for devlink health events
         - ixgbe: add initial support for E610 chipset variant
         - igb: add support for AF_XDP zero-copy
      - Meta:
         - add support for basic RSS config
         - allow changing the number of channels
         - add hardware monitoring support
      - Broadcom (bnxt):
         - implement TCP data split and HDS threshold ethtool support,
           enabling Device Memory TCP.
      - Marvell Octeon:
         - implement egress ipsec offload support for the cn10k family
      - Hisilicon (HIBMC):
         - implement unicast MAC filtering

Pull networking updates from Paolo Abeni:
 "This is slightly smaller than usual, with the most interesting work
  being still around RTNL scope reduction.

  Core:

   - More core refactoring to reduce the RTNL lock contention, including
     preparatory work for the per-network namespace RTNL lock, replacing
     RTNL lock with a per device-one to protect NAPI-related net device
     data and moving synchronize_net() calls outside such lock.

   - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
     and more specific TCP coverage.

   - Reduce network namespace tear-down time by removing per-subsystems
     synchronize_net() in tipc and sched.

   - Add flow label selector support for fib rules, allowing traffic
     redirection based on such header field.

  Netfilter:

   - Do not remove netdev basechain when last device is gone, allowing
     netdev basechains without devices.

   - Revisit the flowtable teardown strategy, dealing better with fin,
     reset and re-open events.

   - Scale-up IP-vs connection dumping by avoiding linear search on each
     restart.

  Protocols:

   - A significant XDP socket refactor, consolidating and optimizing
     several helpers into the core

   - Better scaling of ICMP rate-limiting, by removing false-sharing in
     inet peers handling.

   - Introduces netlink notifications for multicast IPv4 and IPv6
     address changes.

   - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
     aggregation and fragmentation of the inner IP.

   - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
     avoid local port exhaustion issues when the average connection
     lifetime is very short.

   - Support updating keys (re-keying) for connections using kernel TLS
     (for TLS 1.3 only).

   - Support ipv4-mapped ipv6 address clients in smc-r v2.

   - Add support for jumbo data packet transmission in RxRPC sockets,
     gluing multiple data packets in a single UDP packet.

   - Support RxRPC RACK-TLP to manage packet loss and retransmission in
     conjunction with the congestion control algorithm.

  Driver API:

   - Introduce a unified and structured interface for reporting PHY
     statistics, exposing consistent data across different H/W via
     ethtool.

   - Make timestamping selectable, allow the user to select the desired
     hwtstamp provider (PHY or MAC) administratively.

   - Add support for configuring a header-data-split threshold (HDS)
     value via ethtool, to deal with partial or buggy H/W
     implementation.

   - Consolidate DSA drivers Energy Efficiency Ethernet support.

   - Add EEE management to phylink, making use of the phylib
     implementation.

   - Add phylib support for in-band capabilities negotiation.

   - Simplify how phylib-enabled mac drivers expose the supported
     interfaces.

  Tests and tooling:

   - Make the YNL tool package-friendly to make it easier to deploy it
     separately from the kernel.

   - Increase TCP selftest coverage importing several packetdrill
     test-cases.

   - Regenerate the ethtool uapi header from the YNL spec, to ease
     maintenance and future development.

   - Add YNL support for decoding the link types used in net self-tests,
     allowing a single build to run both net and drivers/net.

kthread_create() creates a kthread without running it yet. kthread_run()
creates a kthread and runs it.

On the other hand, kthread_create_worker() creates a kthread worker and
runs it.

This difference in behaviours is confusing. Also there is no way to
create a kthread worker and affine it using kthread_bind_mask() or
kthread_affine_preferred() before starting it.

Consolidate the behaviours and introduce kthread_run_worker[_on_cpu]()
that behaves just like kthread_run(). kthread_create_worker[_on_cpu]()
will now only create a kthread worker without starting it.
