      devlink: use _BITUL() macro instead of BIT() in the UAPI header · 75f4d454
      Tobias Klauser authored
      The BIT() macro is not available for the UAPI headers. Moreover, it can
      be defined differently in user space headers. Thus, replace its usage
      with the _BITUL() macro which is already used in other macro definitions
      in <linux/devlink.h>.

      The ndo_start_xmit() method must not attempt to free the skb to transmit
      when returning NETDEV_TX_BUSY. Therefore, make sure the
      korina_send_packet() function returns NETDEV_TX_OK when it frees a packet.

      net/smc: fix access to parent of an ib device · 995433b7
      Karsten Graul authored
      The parent of an ib device is used to retrieve the PCI device
      attributes. It turns out that there are possible cases when an ib device
      has no parent set in the device structure, which may lead to page
      faults when trying to access this memory.
      Fix that by checking the parent pointer and consolidate the pci device
      specific processing in a new function.

      dpaa2-eth: fix the size of the mapped SGT buffer · 54a57d1c
      Ioana Ciornei authored
      This patch fixes an error condition triggered when the code path which
      transmits a S/G frame descriptor when the skb's headroom is not enough
      for DPAA2's needs.
      
      We are greated with a splat like the one below when a SGT structure is
      recycled and that is because even though a dma_unmap is performed on the
      Tx confirmation path, the unmap is not done with the proper size.

      The dpaa2-eth driver uses an area of software annotations to transmit

      dealing with: linear, S/G or XDP.
      
      The commit referenced was incorrectly setting up the 'sgt_size' field
      for the S/G type of SWA even though we are dealing with a linear skb
      here.

      i40e, xsk: clear the status bits for the next_to_use descriptor · 64050b5b
      Björn Töpel authored
      On the Rx side, the next_to_use index points to the next item in the
      HW ring to be refilled/allocated, and next_to_clean points to the next
      item to potentially be processed.
      
      When the HW Rx ring is fully refilled, i.e. no packets has been
      processed, the next_to_use will be next_to_clean - 1. When the ring is
      fully processed next_to_clean will be equal to next_to_use. The latter
      case is where a bug is triggered.
      
      If the next_to_use bits are not cleared, and the "fully processed"
      state is entered, a stale descriptor can be processed.
      
      The skb-path correctly clear the status bit for the next_to_use
      descriptor, but the AF_XDP zero-copy path did not do that.
      
      This change adds the status bits clearing of the next_to_use
      descriptor.

      lan743x: fix rx_napi_poll/interrupt ping-pong · 57030a0b
      Sven Van Asbroeck authored
      Even if there is more rx data waiting on the chip, the rx napi poll fn
      will never run more than once - it will always read a few buffers, then
      bail out and re-arm interrupts. Which results in ping-pong between napi
      and interrupt.
      
      This defeats the purpose of napi, and is bad for performance.
      
      Fix by making the rx napi poll behave identically to other ethernet
      drivers:
      1. initialize rx napi polling with an arbitrary budget (64).
      2. in the polling fn, return full weight if rx queue is not depleted,
         this tells the napi core to "keep polling".
      3. update the rx tail ("ring the doorbell") once for every 8 processed
         rx ring buffers.
      
      Thanks to Jakub Kicinski, Eric Dumazet and Andrew Lunn for their expert
      opinions and suggestions.

           help distros/users testing new stuff more easily; the kconfig was
           moved to boot time option, too

      Range checks can folded into proper conversion function.  kstrto*() exist
      for all arithmetic types.

      mm: fix fall-through warnings for Clang · 01359eb2
      Gustavo A. R. Silva authored
      In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple of
      warnings by explicitly adding a break statement instead of just letting
      the code fall through to the next, and by adding a fallthrough
      pseudo-keyword in places where the code is intended to fall through.

      mm: slub: convert sysfs sprintf family to sysfs_emit/sysfs_emit_at · bf16d19a
      Joe Perches authored
      Convert the unbounded uses of sprintf to sysfs_emit.
      
      A few conversions may now not end in a newline if the output buffer is
      overflowed.

      mm: shmem: convert shmem_enabled_show to use sysfs_emit_at · 79d4d38a
      Joe Perches authored
      Update the function to use sysfs_emit_at while neatening the uses of
      sprintf and overwriting the last space char with a newline to avoid
      possible output buffer overflow.
      
      Miscellanea:
      
       - in shmem_enabled_show, the removal of the indirected use of fmt
         allows __printf verification

      mm:backing-dev: use sysfs_emit in macro defining functions · 5e4c0d86
      Joe Perches authored
      The cocci script used in commit bdacbb8d04f ("mm: Use sysfs_emit for
      struct kobject * uses") does not convert the name##_show macro because the
      macro uses concatenation via ##.
      
      Convert it by hand.
