      qed: implement devlink dump · 27fed787
      Igor Russkikh authored
      Gather and push out full device dump to devlink.
      Device dump is the same as with `ethtool -d`, but now its generated
      exactly at the moment bad thing happens.

      qed: implement devlink info request · 53916a67
      Igor Russkikh authored
      Here we return existing fw & mfw versions, we also fetch device's

            stored:
              fw.mgmt 8.52.10.0
      
      MFW and FW are different firmwares on device.
      Management is a firmware responsible for link configuration and
      various control plane features. Its permanent and resides in NVM.
      
      Running FW (or fastpath FW) is an embedded microprogram implementing
      all the packet processing, offloads, etc. This FW is being loaded
      on each start by the driver from FW binary blob.
      
      The base device specific structure (qed_dev_info) was not directly
      available to the base driver before. Thus, here we create and store
      a private copy of this structure in qed_dev root object to
      access the data.

      qed/qede: make devlink survive recovery · 755f982b
      Igor Russkikh authored
      Devlink instance lifecycle was linked to qed_dev object,
      that caused devlink to be recreated on each recovery.
      
      Changing it by making higher level driver (qede) responsible for its
      life. This way devlink now survives recoveries.
      
      qede now stores devlink structure pointer as a part of its device
      object, devlink private data contains a linkage structure,
      qed_devlink.

      chelsio: switch from 'pci_' to 'dma_' API · 9ab90179
      Christophe JAILLET authored
      The wrappers in include/linux/pci-dma-compat.h should go away.
      
      The patch has been generated with the coccinelle script below and has been
      hand modified to replace GFP_ with a correct flag.
      It has been compile tested.
      
      When memory is allocated in 'free_rx_resources()' and
      'alloc_tx_resources()' (sge.c) GFP_KERNEL can be used because it is
      already used in these functions.
      
      Moreover, they can only be called from a .ndo_open	function. So it is
      guarded by the 'rtnl_lock()', which is a mutex.
      
      While at it, a pr_err message in 'init_one()' has been updated accordingly
      (s/consistent/coherent).

      ====================
      mlxsw: Misc updates
      
      This patch set includes various updates for mlxsw.
      
      Patches #1-#4 adjust the default burst size of packet trap policers to
      conform to Spectrum-{2,3} requirements. The corresponding selftest is
      also adjusted so that it could reliably pass on these platforms.
      
      Patch #5 adjusts a selftest so that it could pass with both old and new
      versions of mausezahn.
      
      Patch #6 significantly reduces the runtime of tc-police scale test by
      changing the preference and masks of the used tc filters.
      
      Patch #7 prevents the driver from trying to set invalid ethtool link
      modes.

      mlxsw: spectrum_ethtool: Remove internal speeds from PTYS register · 5bf01b57
      Danielle Ratson authored
      The PTYS register is used to report and configure the port type and
      speed. Currently, internal bits in the register are used the same way
      other bits are used.
      
      Using the internal bits can cause bad parameter firmware errors. For
      example, trying to write to internal bit 25 returns:
      
      EMAD reg access failed (tid=53e2bffa00004310,reg_id=5004(ptys),type=write,status=7(bad parameter))
      
      Remove the internal bits from the PTYS register, so that it is no longer
      possible to pass them to firmware.

      selftests: mlxsw: Reduce runtime of tc-police scale test · ffff9c9c
      Ido Schimmel authored
      Currently, the test takes about 626 seconds to complete because of an
      inefficient use of the device's TCAM. Reduce the runtime to 202 seconds
      by inserting all the flower filters with the same preference and mask,
      but with a different key.
      
      In particular, this reduces the deletion of the qdisc (which triggers
      the deletion of all the filters) from 66 seconds to 0.2 seconds. This
      prevents various netlink requests from user space applications (e.g.,
      systemd-networkd) from timing-out because RTNL is not held for too long
      anymore.

      selftests: forwarding: Fix mausezahn delay parameter in mirror_test() · 24f54c52
      Danielle Ratson authored
      Currently, mausezahn delay parameter in mirror_test() is specified with
      'ms' units.
      
      mausezahn versions before 0.6.5 interpret 'ms' as seconds and therefore
      the tests that use mirror_test() take a very long time to complete.
      
      Resolve this by specifying 'msec' units.

      'atl1_setup_ring_resources()' (atl1.c) can also be called from a
      '.set_ringparam' (see struct ethtool_ops) where sleep is also allowed.
      
      Both cases are protected by 'rtnl_lock()' which is a mutex. So these
      function can sleep.

      starfire: switch from 'pci_' to 'dma_' API · 5d63ccea
      Christophe JAILLET authored
      The wrappers in include/linux/pci-dma-compat.h should go away.
      
      The patch has been generated with the coccinelle script below and has been
      hand modified to replace GFP_ with a correct flag.
      It has been compile tested.
      
      When memory is allocated in 'netdev_open()', GFP_ATOMIC must be used
      because it can be called from a .ndo_tx_timeout function.
      So this function can be called with the 'netif_tx_lock' acquired.
      The call chain is:
        --> tx_timeout                 (.ndo_tx_timeout function)
          --> netdev_open

      The patch has been generated with the coccinelle script below and has been
      hand modified to replace GFP_ with a correct flag.
      It has been compile tested.
      
      When memory is allocated in 'typhoon_init_one()' GFP_KERNEL can be used
      because it is a probe function and no lock is acquired.
      
      When memory is allocated in 'typhoon_download_firmware()', GFP_ATOMIC
      must be used because it can be called from a .ndo_tx_timeout function.
      So this function can be called with the 'netif_tx_lock' acquired.
      The call chain is:
        --> typhoon_tx_timeout                 (.ndo_tx_timeout function)
          --> typhoon_start_runtime
            --> typhoon_download_firmware
      
      While at is, update some comments accordingly.

      io_uring: ignore POLLIN for recvmsg on MSG_ERRQUEUE · 901341bb
      Luke Hsiao authored
      Currently, io_uring's recvmsg subscribes to both POLLERR and POLLIN. In
      the context of TCP tx zero-copy, this is inefficient since we are only
      reading the error queue and not using recvmsg to read POLLIN responses.
      
      This patch was tested by using a simple sending program to call recvmsg
      using io_uring with MSG_ERRQUEUE set and verifying with printks that the
      POLLIN is correctly unset when the msg flags are MSG_ERRQUEUE.

      io_uring: allow tcp ancillary data for __sys_recvmsg_sock() · 583bbf06
      Luke Hsiao authored
      For TCP tx zero-copy, the kernel notifies the process of completions by
      queuing completion notifications on the socket error queue. This patch
      allows reading these notifications via recvmsg to support TCP tx
      zero-copy.
      
      Ancillary data was originally disallowed due to privilege escalation
      via io_uring's offloading of sendmsg() onto a kernel thread with kernel
      credentials (https://crbug.com/project-zero/1975). So, we must ensure
      that the socket type is one where the ancillary data types that are
      delivered on recvmsg are plain data (no file descriptors or values that
      are translated based on the identity of the calling process).
      
      This was tested by using io_uring to call recvmsg on the MSG_ERRQUEUE
      with tx zero-copy enabled. Before this patch, we received -EINVALID from
      this specific code path. After this patch, we could read tcp tx
      zero-copy completion notifications from the MSG_ERRQUEUE.

      ====================
      devlink fixes for port and reporter field access
      
      These series contains two small fixes of devlink.
      
      Patch-1 initializes port reporter fields early enough to
      avoid access before initialized error.
      Patch-2 protects port list lock during traversal.

      devlink: Fix per port reporter fields initialization · 79604c5d
      Parav Pandit authored
      Cited patch in fixes tag initializes reporters_list and reporters_lock
      of a devlink port after devlink port is added to the list. Once port
      is added to the list, devlink_nl_cmd_health_reporter_get_dumpit()
      can access the uninitialized mutex and reporters list head.
      Fix it by initializing port reporters field before adding port to the
      list.
