 "A handful of clk driver fixes.

  Mostly they're around the i.MX drivers fixing the parents of a few
  clks and making KASAN happy with how the message passing code works.

  Besides that we have a TI driver fix for the RTC parent and a fix for
  the basic gate type registration functions introduced this release
  where they didn't actually pass the arguments in the right places to
  the multiplexer function down below"

      zonfs: Fix handling of read-only zones · ccf4ad7d
      由 Damien Le Moal 提交于 
      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.

Mellanox, mlx5 fixes 2020-03-24

This series introduces some fixes to mlx5 driver.

From Aya, Fixes to the RX error recovery flows
From Leon, Fix IB capability mask

Please pull and let me know if there is any problem.

For -stable v5.5
 ('net/mlx5_core: Set IB capability mask1 to fix ib_srpt connection failure')

For -stable v5.4
 ('net/mlx5e: Fix ICOSQ recovery flow with Striding RQ')
 ('net/mlx5e: Do not recover from a non-fatal syndrome')
 ('net/mlx5e: Fix missing reset of SW metadata in Striding RQ reset')
 ('net/mlx5e: Enhance ICOSQ WQE info fields')

The above patch ('net/mlx5e: Enhance ICOSQ WQE info fields')
will fail to apply cleanly on v5.4 due to a trivial contextual conflict,
but it is an important fix, do I need to do something about it or just
assume Greg will know how to handle this ?

      r8169: re-enable MSI on RTL8168c · f13bc681
      由 Heiner Kallweit 提交于 
      The original change fixed an issue on RTL8168b by mimicking the vendor
driver behavior to disable MSI on chip versions before RTL8168d.
This however now caused an issue on a system with RTL8168c, see [0].
Therefore leave MSI disabled on RTL8168b, but re-enable it on RTL8168c.

      由 Andre Przywara 提交于 
      The DT binding for this PHY describes an *optional* clock property.
Due to a bug in the error handling logic, we are actually ignoring this
clock *all* of the time so far.

Fix this by using devm_clk_get_optional() to handle this clock properly.

      net: dsa: tag_8021q: replace dsa_8021q_remove_header with __skb_vlan_pop · e80f40cb
      由 Vladimir Oltean 提交于 
      Not only did this wheel did not need reinventing, but there is also
an issue with it: It doesn't remove the VLAN header in a way that
preserves the L2 payload checksum when that is being provided by the DSA
master hw.  It should recalculate checksum both for the push, before
removing the header, and for the pull afterwards. But the current
implementation is quite dizzying, with pulls followed immediately
afterwards by pushes, the memmove is done before the push, etc.  This
makes a DSA master with RX checksumming offload to print stack traces
with the infamous 'hw csum failure' message.

So remove the dsa_8021q_remove_header function and replace it with
something that actually works with inet checksumming.

      net: cbs: Fix software cbs to consider packet sending time · 961d0e5b
      由 Zh-yuan Ye 提交于 
      Currently the software CBS does not consider the packet sending time
when depleting the credits. It caused the throughput to be
Idleslope[kbps] * (Port transmit rate[kbps] / |Sendslope[kbps]|) where
Idleslope * (Port transmit rate / (Idleslope + |Sendslope|)) = Idleslope
is expected. In order to fix the issue above, this patch takes the time
when the packet sending completes into account by moving the anchor time
variable "last" ahead to the send completion time upon transmission and
adding wait when the next dequeue request comes before the send
completion time of the previous packet.

changelog:
V2->V3:
 - remove unnecessary whitespace cleanup
 - add the checks if port_rate is 0 before division

V1->V2:
 - combine variable "send_completed" into "last"
 - add the comment for estimate of the packet sending

      RDMA/mlx5: Fix access to wrong pointer while performing flush due to error · 950bf4f1
      由 Leon Romanovsky 提交于 
      The main difference between send and receive SW completions is related to
separate treatment of WQ queue. For receive completions, the initial index
to be flushed is stored in "tail", while for send completions, it is in
deleted "last_poll".
