Get rid of the multiple tenary operators in mtk_gmac0_rgmii_adjust()
replacing them with a single if(), thus making the code easier to read.

Bjorn Helgaas says:
====================
PCI/AER: Remove redundant Device Control Error Reporting Enable
From: Bjorn Helgaas <bhelgaas@google.com>
Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"),
which appeared in v6.0, the PCI core has enabled PCIe error reporting for
all devices during enumeration.
Remove driver code to do this and remove unnecessary includes of
<linux/aer.h> from several other drivers.
Intel folks, sorry that I missed removing the <linux/aer.h> includes in the
first series.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

51b35a454efd ("sfc: skeleton EF100 PF driver") added a call to
pci_disable_pcie_error_reporting() in ef100_pci_remove().
Remove this call since there's no apparent reason to disable error
reporting when it was not previously enabled.
Note that since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is

enumeration, so the driver doesn't need to do it itself.

cd709aa90648 ("bnx2: Add PCI Advanced Error Reporting support.") added
pci_enable_pcie_error_reporting() for all devices, and c239f279e571 ("bnx2:
Enable AER on PCIE devices only") restricted it to BNX2_CHIP_5709 devices
to avoid an error message when it failed on non-PCIe devices. The PCI core
only enables PCIe error reporting on PCIe devices, which I assume means
BNX2_CHIP_5709.

Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).

When sock_alloc_file fails to allocate a file, it will call sock_release.
__sys_socket_file should then not call sock_release again, otherwise there
will be a double free.

syzbot reported struct pid leak [1].
Issue is that queue_oob() calls maybe_add_creds() which potentially
holds a reference on a pid.
But skb->destructor is not set (either directly or by calling
unix_scm_to_skb())
This means that subsequent kfree_skb() or consume_skb() would leak
this reference.
In this fix, I chose to fully support scm even for the OOB message.

R-Car H3 ES1.* was only available to an internal development group and
needed a lot of quirks and workarounds. These become a maintenance
burden now, so our development group decided to remove upstream support
and disable booting for this SoC. Public users only have ES2 onwards.

The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as
internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5
receives corrupted frames, unless port 6 (attached to GMAC0) has been
brought up by the driver. This is true regardless of whether port 5 is
used as a user port or as a CPU port (carrying DSA tags).
Offline debugging (blind for me) which began in the linked thread showed
experimentally that the configuration done by the driver for port 6
contains a step which is needed by port 5 as well - the write to
CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from
the comment "Set core clock into 500Mhz"). Prints put by Arınç show that
the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) |
RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the
MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi
BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both
values of the register, while on the MT7621 SoC it cannot.
The call path that triggers the register write is:
mt753x_phylink_mac_config() for port 6
-> mt753x_pad_setup()
-> mt7530_pad_clk_setup()
so this fully explains the behavior noticed by Arınç, that bringing port
6 up is necessary.
The simplest fix for the problem is to extract the register writes which
are needed for both port 5 and 6 into a common mt7530_pll_setup()
function, which is called at mt7530_setup() time, immediately after
switch reset. We can argue that this mirrors the code layout introduced
in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once
after the reset"), in that the PLL setup has the exact same positioning,
and further work to consolidate the separate setup() functions is not
hindered.
Testing confirms that:
- the slight reordering of writes to MT7530_P6ECR and to
CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not
appear to cause problems for the operation of port 6 on MT7621 and on
MT7623 (where port 5 also always worked)
- packets sent through port 5 are not corrupted anymore, regardless of
whether port 6 is enabled by phylink or not (or even present in the
device tree)
My algorithm for determining the Fixes: tag is as follows. Testing shows
that some logic from mt7530_pad_clk_setup() is needed even for port 5.
Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK
API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so
port 5 included. That commit replaced it with a temporary "Port 5 is not
supported!" comment, and the following commit 38f790a80560 ("net: dsa:
mt7530: Add support for port 5") replaced that comment with a
configuration procedure in mt7530_setup_port5() which was insufficient
for port 5 to work. I'm laying the blame on the patch that claimed
support for port 5, although one would have also needed the change from
commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII
mode") for the write to be performed completely independently from port
6's configuration.
Thanks go to Arınç for describing the problem, for debugging and for
testing.

The implementation of 'current' on x86 is very intentionally special: it
is a very common thing to look up, and it uses 'this_cpu_read_stable()'
to get the current thread pointer efficiently from per-cpu storage.
And the keyword in there is 'stable': the current thread pointer never
changes as far as a single thread is concerned. Even if when a thread
is preempted, or moved to another CPU, or even across an explicit call
'schedule()' that thread will still have the same value for 'current'.
It is, after all, the kernel base pointer to thread-local storage.
That's why it's stable to begin with, but it's also why it's important
enough that we have that special 'this_cpu_read_stable()' access for it.
So this is all done very intentionally to allow the compiler to treat
'current' as a value that never visibly changes, so that the compiler
can do CSE and combine multiple different 'current' accesses into one.
However, there is obviously one very special situation when the
currently running thread does actually change: inside the scheduler
itself.
So the scheduler code paths are special, and do not have a 'current'
thread at all. Instead there are _two_ threads: the previous and the
next thread - typically called 'prev' and 'next' (or prev_p/next_p)
internally.
So this is all actually quite straightforward and simple, and not all
that complicated.
Except for when you then have special code that is run in scheduler
context, that code then has to be aware that 'current' isn't really a
valid thing. Did you mean 'prev'? Did you mean 'next'?
In fact, even if then look at the code, and you use 'current' after the
new value has been assigned to the percpu variable, we have explicitly
told the compiler that 'current' is magical and always stable. So the
compiler is quite free to use an older (or newer) value of 'current',
and the actual assignment to the percpu storage is not relevant even if
it might look that way.
Which is exactly what happened in the resctl code, that blithely used
'current' in '__resctrl_sched_in()' when it really wanted the new
process state (as implied by the name: we're scheduling 'into' that new
resctl state). And clang would end up just using the old thread pointer
value at least in some configurations.
This could have happened with gcc too, and purely depends on random
compiler details. Clang just seems to have been more aggressive about
moving the read of the per-cpu current_task pointer around.
The fix is trivial: just make the resctl code adhere to the scheduler
rules of using the prev/next thread pointer explicitly, instead of using
'current' in a situation where it just wasn't valid.
That same code is then also used outside of the scheduler context (when
a thread resctl state is explicitly changed), and then we will just pass
in 'current' as that pointer, of course. There is no ambiguity in that
case.
The fix may be trivial, but noticing and figuring out what went wrong
was not. The credit for that goes to Stephane Eranian.

Commit 62622dab0a28 ("ima: return IMA digest value only when IMA_COLLECTED
flag is set") caused bpf_ima_inode_hash() to refuse to give non-fresh
digests. IMA test #3 assumed the old behavior, that bpf_ima_inode_hash()
still returned also non-fresh digests.
Correct the test by accepting both cases. If the samples returned are 1,
assume that the commit above is applied and that the returned digest is
fresh. If the samples returned are 2, assume that the commit above is not
applied, and check both the non-fresh and fresh digest.

This test runs on the client-router-server topo, and monitors the traffic
on the RX devices of router and server while sending BIG TCP packets with
netperf from client to server. Meanwhile, it changes 'tso' on the TX devs
and 'gro' on the RX devs. Then it checks if any BIG TCP packets appears
on the RX devs with 'ip/ip6tables -m length ! --length 0:65535' for each
case.
Note that we also add tc action ct in link1 ingress to cover the ipv6

For IPv6 Jumbo packets, the ipv6_hdr(skb)->payload_len is always 0,
and its real payload_len ( > 65535) is saved in hbh exthdr. With 0
length for the jumbo packets, all data and exthdr will be trimmed
in nf_ct_skb_network_trim().
