The test seems to expect that nc will exit after the first
received message. This is not the case with Ncat 7.94.
There are multiple versions of nc out there, switch
to socat for better compatibility.
Tell socat to exit after 128 bytes and pad the message.
Since the test sets -e make sure we don't set exit code
(|| true) and print the pass / fail rather then silently
moving over the test and just setting non-zero exit code
with no output indicating what failed.

gem_poll_controller() disables interrupts, which may sleep.
We can't sleep in netpoll, it has interrupts disabled completely.
Strangely, gem_poll_controller() doesn't even poll the completions,
and instead acts as if an interrupt has fired so it just schedules
NAPI and exits. None of this has been necessary for years, since
netpoll invokes NAPI directly.

According to hardware limitation, for device support modify
VLAN filter state but not support bypass port VLAN filter,
it should always disable the port VLAN filter. but the driver
enables port VLAN filter when initializing, if there is no
VLAN(except VLAN 0) id added, the driver will disable it
in service task. In most time, it works fine. But there is
a time window before the service task shceduled and net device

will not update the VLAN filter state, and the port VLAN filter
remains enabled.
To fix the problem, if support modify VLAN filter state but not

Up till now the code to start HSR announce timer, which triggers sending
supervisory frames, was assuming that hsr_netdev_notify() would be called
at least twice for hsrX interface. This was required to have different
values for old and current values of network device's operstate.
This is problematic for a case where hsrX interface is already in the
operational state when hsr_netdev_notify() is called, so timer is not
configured to trigger and as a result the hsrX is not sending supervisory
frames to HSR ring.
This error has been discovered when hsr_ping.sh script was run. To be
more specific - for the hsr1 and hsr2 the hsr_netdev_notify() was
called at least twice with different IF_OPER_{LOWERDOWN|DOWN|UP} states
assigned in hsr_check_carrier_and_operstate(hsr). As a result there was
no issue with sending supervisory frames.
However, with hsr3, the notify function was called only once with
operstate set to IF_OPER_UP and timer responsible for triggering
supervisory frames was not fired.
The solution is to use netif_oper_up() and netif_running() helper
functions to assess if network hsrX device is up.
Only then, when the timer is not already pending, it is started.
Otherwise it is deactivated.

Several clocks as well as both sgmiisys phandles were added by mistake
to the Ethernet bindings for MT7988. Also, the total number of clocks
didn't match with the actual number of items listed.
This happened because the vendor driver which served as a reference uses
a high number of syscon phandles to access various parts of the SoC
which wasn't acceptable upstream. Hence several parts which have never
previously been supported (such SerDes PHY and USXGMII PCS) are going to
be implemented by separate drivers. As a result the device tree will
look much more sane.
Quickly align the bindings with the upcoming reality of the drivers
actually adding support for the remaining Ethernet-related features of
the MT7988 SoC.

Only generate one ACK packet for all the subpackets in a jumbo packet. If
we would like to generate more than one ACK, we prioritise them base on
their reason code, in the order, highest first:
OutOfSeq > NoSpace > ExceedsWin > Duplicate > Requested > Delay > Idle
For the first four, we reference the lowest offending subpacket; for the
last three, the highest.
This reduces the number of ACKs we end up transmitting to one per UDP
packet transmitted to reduce network loading and packet parsing.

Make the following fixes to the congestion control algorithm:
(1) Don't vary the cwnd starting value by the size of RXRPC_TX_SMSS since
that's currently held constant - set to the size of a jumbo subpacket
payload so that we can create jumbo packets on the fly. The current
code invariably picks 3 as the starting value.
Further, the starting cwnd needs to be an even number because we ack
every other packet, so set it to 4.
(2) Don't cut ssthresh when we see an ACK come from the peer with a
receive window (rwind) less than ssthresh. ssthresh keeps track of
characteristics of the connection whereas rwind may be reduced by the
peer for any reason - and may be reduced to 0.

When creating the topology for the test, three veth pairs are created in
the initial network namespace before being moved to one of the network
namespaces created by the test.
On systems where systemd-udev uses MACAddressPolicy=persistent (default
since systemd version 242), this will result in some net devices having
the same MAC address since they were created with the same name in the
initial network namespace. In turn, this leads to arping / ndisc6
failing since packets are dropped by the bridge's loopback filter.
Fix by creating each net device in the correct network namespace instead
of moving it there from the initial network namespace.

When a broadcast AppleTalk packet is received, prefer queuing it on the
socket whose address matches the address of the interface that received
the packet (and is listening on the correct port). Userspace
applications that handle such packets will usually send a response on
the same socket that received the packet; this fix allows the response
to be sent on the correct interface.
If a socket matching the interface's address is not found, an arbitrary
socket listening on the correct port will be used, if any. This matches
the implementation's previous behavior.
Fixes atalkd's responses to network information requests when multiple
network interfaces are configured to use AppleTalk.

This meant it could race with device removal; it could increment the

a superblock write was silently dropped.

One more Qualcomm Arm64 DeviceTree fix for v6.9
On ths SA8155P automotive platform, the wrong gpio controller is defined
for the SD-card detect pin, which depending on probe ordering of things
cause ethernet to be broken. The card detect pin reference is corrected
to solve this problem.

Pull btrfs fixes from David Sterba:
"Two more fixes, both have some visible effects on user space:
- add check if quotas are enabled when passing qgroup inheritance
info, this affects snapper that could fail to create a snapshot
- do check for leaf/node flag WRITTEN earlier so that nodes are
completely validated before access, this used to be done by
integrity checker but it's been removed and left an unhandled case"
* tag 'for-6.9-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: make sure that WRITTEN is set on all metadata blocks
btrfs: qgroup: do not check qgroup inherit if qgroup is disabled
This reverts commit 07ed11afb6.
Stephen Rostedt reports:
"I went to run my tests on my VMs and the tests hung on boot up.
Unfortunately, the most I ever got out was:
[ 93.607888] Testing event system initcall: OK
[ 93.667730] Running tests on all trace events:
[ 93.669757] Testing all events: OK
[ 95.631064] ------------[ cut here ]------------
Timed out after 60 seconds"
and further debugging points to a possible circular locking dependency
between the console_owner locking and the worker pool locking.
Reverting the commit allows Steve's VM to boot to completion again.
[ This may obviously result in the "[TTM] Buffer eviction failed"
messages again, which was the reason for that original revert. But at
this point this seems preferable to a non-booting system... ]

Pull slab fixes from Vlastimil Babka:
- Fix for cleanup infrastructure (Dan Carpenter)
This makes the __free(kfree) cleanup hooks not crash on error
pointers.
- SLUB fix for freepointer checking (Nicolas Bouchinet)
This fixes a recently introduced bug that manifests when
init_on_free, CONFIG_SLAB_FREELIST_HARDENED and consistency checks
(slub_debug=F) are all enabled, and results in false-positive
freepointer corrupt reports for caches that store freepointer outside
of the object area.
