The set flag NFT_SET_EXPR provides a hint to the kernel that userspace
supports for multiple expressions per set element. In the same
direction, NFT_DYNSET_F_EXPR specifies that dynset expression defines
multiple expressions per set element.

This allows new userspace software with old kernels to bail out with
EOPNOTSUPP. This update is similar to ef516e86 ("netfilter:
nf_tables: reintroduce the NFT_SET_CONCAT flag"). The NFT_SET_EXPR flag
needs to be set on when the NFTA_SET_EXPRESSIONS attribute is specified.
The NFT_SET_EXPR flag is not set on with NFTA_SET_EXPR to retain
backward compatibility in old userspace binaries.

Commit f9c6cea0 ("ibmvnic: Skip fatal error reset after passive init")
says "If the passive
CRQ initialization occurs before the FATAL reset task is processed,
the FATAL error reset task would try to access a CRQ message queue
that was freed, causing an oops. The problem may be most likely to
occur during DLPAR add vNIC with a non-default MTU, because the DLPAR
process will automatically issue a change MTU request.
Fix this by not processing fatal error reset if CRQ is passively
initialized after client-driven CRQ initialization fails."

The original commit skips a specific reset condition, but that does
not fix the problem it claims to fix, and misses a reset condition.
The effective fix is commit 0e435bef ("ibmvnic: fix NULL pointer
dereference in ibmvic_reset_crq") and commit a0faaa27 ("ibmvnic:

DCB uses the same handler function for both RTM_GETDCB and RTM_SETDCB
messages. dcb_doit() bounces RTM_SETDCB mesasges if the user does not have
the CAP_NET_ADMIN capability.

However, the operation to be performed is not decided from the DCB message
type, but from the DCB command. Thus DCB_CMD_*_GET commands are used for
reading DCB objects, the corresponding SET and DEL commands are used for
manipulation.

The assumption is that set-like commands will be sent via an RTM_SETDCB
message, and get-like ones via RTM_GETDCB. However, this assumption is not
enforced.

It is therefore possible to manipulate DCB objects without CAP_NET_ADMIN
capability by sending the corresponding command in an RTM_GETDCB message.
That is a bug. Fix it by validating the type of the request message against
the type used for the response.

====================
net: ipa: GSI interrupt handling fixes

This series implements fixes for some issues related to handling
interrupts when GSI channel and event ring commands complete.

The first issue is that the completion condition for an event ring
or channel command could occur while the associated interrupt is
disabled.  This would cause the interrupt to fire when it is
subsequently enabled, even if the condition it signals had already
been handled.  The fix is to clear any pending interrupt conditions
before re-enabling the interrupt.

The second and third patches change how the success of an event ring
or channel command is determined.  These commands change the state
of an event ring or channel.  Previously the receipt of a completion
interrupt was required to consider a command successful.  Instead, a
command is successful if it changes the state of the target event
ring or channel in the way expected.  This way the command can
succeed even if the completion interrupt did not arrive while it was
enabled.

This patch implements the same basic fix for event rings as the
previous one does for channels.

The result of issuing an event ring control command should be that
the event ring changes state.  If enabled, a completion interrupt
signals that the event ring state has changed.  This interrupt is
enabled by gsi_evt_ring_command() and disabled again after the
command has completed (or we time out).

There is a window of time during which the command could complete
successfully without interrupting.  This would cause the event ring
to transition to the desired new state.

So whether a event ring command ends via completion interrupt or
timeout, we can consider the command successful if the event ring
has entered the desired state (and a failure if it has not,
regardless of the cause).

We enable the completion interrupt for channel or event ring
commands only when we issue them.  The interrupt is disabled after
the interrupt has fired, or after we have timed out waiting for it.

If we time out, the command could complete after the interrupt has
been disabled, causing a state change in the channel or event ring.
The interrupt associated with that state change would be delivered
the next time the completion interrupt is enabled.

To avoid previous command completions interfering with new commands,
clear all pending completion interrupts before re-enabling them for
a new command.

When searching for inactive maintainers it's useful to filter
out mailing list addresses. Such "maintainers" will obviously
never feature in a "From:" line of an email or a review tag.

Since "L:" entries only provide the address of a mailing list
without a fancy name extend this pattern to "M:" entries.

Alternatively we could reserve M: entries for humans only
and move the fake "maintainers" to L:. While I'd personally
prefer to reserve M: for humans only, I'm not 100% that's
a great choice either, given most L: entries are in fact

The dwmac glue registers on Amlogic Meson8b and newer SoCs has two clock
inputs:
- Meson8b and Meson8m2: MPLL2 and MPLL2 (the same parent is wired to
  both inputs)
- GXBB, GXL, GXM, AXG, G12A, G12B, SM1: FCLK_DIV2 and MPLL2

All known vendor kernels and u-boots are using the first input only. We
let the common clock framework automatically choose the "right" parent.
For some boards this causes a problem though, specificially with G12A and
newer SoCs. The clock input is used for generating the 125MHz RGMII TX
clock. For the two input clocks this means on G12A:
- FCLK_DIV2: 999999985Hz / 8 = 124999998.125Hz
- MPLL2: 499999993Hz / 4 = 124999998.25Hz

In theory MPLL2 is the "better" clock input because it's gets us 0.125Hz
closer to the requested frequency than FCLK_DIV2. In reality however
there is a resource conflict because MPLL2 is needed to generate some of
the audio clocks. dwmac-meson8b probes first and sets up the clock tree
with MPLL2. This works fine until the audio driver comes and "steals"
the MPLL2 clocks and configures it with it's own rate (294909637Hz). The
common clock framework happily changes the MPLL2 rate but does not
reconfigure our RGMII TX clock tree, which then ends up at 73727409Hz,
which is more than 40% off the requested 125MHz.

Don't use the second clock input for now to force the common clock
framework to always select the first parent. This mimics the behavior
from the vendor driver and fixes the clock resource conflict with the
audio driver on G12A boards. Once the common clock framework can handle
this situation this change can be reverted again.

Table 8-53 in the QUICC Engine Reference manual shows definitions of

one does find the text

  Base Address of the Global Transmitter Parameter RAM Page. [...]
  The user needs to allocate 128 bytes for this page. The address must
  be aligned to the page size.

I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).

Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).

I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.

All the buffers and registers are already set up appropriately for an

The last line explains what the DSA stack tries to do: achieving an MTU

Similar to mmio code path, remove wake logic in mt76u_status_worker handler.
Starting from commit 90d494c9 ("mt76: improve tx queue stop/wake")', the
wake queue logic on the usb status path is no longer necessary since the hw
queues are no longer stopped on the mt76 tx path.

Issue:
Flow control frame used to pause GoP(MAC) was delivered to the CPU
and created a load on the CPU. Since XOFF/XON frames are used only
by MAC, these frames should be dropped inside MAC.

Fix:
According to 802.3-2012 - IEEE Standard for Ethernet pause frame
has unique destination MAC address 01-80-C2-00-00-01.
Add TCAM parser entry to track and drop pause frames by destination MAC.
