      parse-maintainers: Do not sort section content by default · 5cdbec10

      Add an --order switch to control section reordering.
      Default for --order is off.
      
      Change the default ordering to a slightly more sensible:
      
      M:  Person acting as a maintainer
      R:  Person acting as a patch reviewer
      L:  Mailing list where patches should be sent

      To avoid a direct dependency with tc actions from netfilter, wrap the
      redirect bits around CONFIG_NET_REDIRECT and move helpers to
      include/linux/skbuff.h. Turn on this toggle from the ifb driver, the
      only existing client of these bits in the tree.
      
      This patch adds skb_set_redirected() that sets on the redirected bit
      on the skbuff, it specifies if the packet was redirect from ingress
      and resets the timestamp (timestamp reset was originally missing in the
      netfilter bugfix).

      net: ena: Add PCI shutdown handler to allow safe kexec · 428c4913
      Guilherme G. Piccoli authored
      Currently ENA only provides the PCI remove() handler, used during rmmod
      for example. This is not called on shutdown/kexec path; we are potentially
      creating a failure scenario on kexec:
      
      (a) Kexec is triggered, no shutdown() / remove() handler is called for ENA;
      instead pci_device_shutdown() clears the master bit of the PCI device,
      stopping all DMA transactions;
      
      (b) Kexec reboot happens and the device gets enabled again, likely having
      its FW with that DMA transaction buffered; then it may trigger the (now
      invalid) memory operation in the new kernel, corrupting kernel memory area.
      
      This patch aims to prevent this, by implementing a shutdown() handler
      quite similar to the remove() one - the difference being the handling
      of the netdev, which is unregistered on remove(), but following the
      convention observed in other drivers, it's only detached on shutdown().
      
      This prevents an odd issue in AWS Nitro instances, in which after the 2nd
      kexec the next one will fail with an initrd corruption, caused by a wild
      DMA write to invalid kernel memory. The lspci output for the adapter
      present in my instance is:
      
      00:05.0 Ethernet controller [0200]: Amazon.com, Inc. Elastic Network
      Adapter (ENA) [1d0f:ec20]

      zonfs: Fix handling of read-only zones · ccf4ad7d
      Damien Le Moal authored
      The write pointer of zones in the read-only consition is defined as
      invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not
      possible to determine the correct size of a read-only zone file on
      mount. Fix this by handling read-only zones in the same manner as
      offline zones by disabling all accesses to the zone (read and write)
      and initializing the inode size of the read-only zone to 0).
      
      For zones found to be in the read-only condition at runtime, only
      disable write access to the zone and keep the size of the zone file to
      its last updated value to allow the user to recover previously written
      data.
      
      Also fix zonefs documentation file to reflect this change.

      ====================
      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for net:
      
      1) A new selftest for nf_queue, from Florian Westphal. This test
         covers two recent fixes: 07f8e4d0 ("tcp: also NULL skb->dev
         when copy was needed") and b738a185 ("tcp: ensure skb->dev is
         NULL before leaving TCP stack").
      
      2) The fwd action breaks with ifb. For safety in next extensions,
         make sure the fwd action only runs from ingress until it is extended
         to be used from a different hook.
      
      3) The pipapo set type now reports EEXIST in case of subrange overlaps.
         Update the rbtree set to validate range overlaps, so far this
         validation is only done only from userspace. From Stefano Brivio.

      The original change fixed an issue on RTL8168b by mimicking the vendor
