The while loop condition verifies 'count < limit'. Neither value change
before the 'count >= limit' check. As is this check is dead code. But
code inspection reveals a code path that modifies 'count' and then goto
'drain_data' and back to 'read_again'. So there is a need to verify
count value sanity after 'read_again'.
Move 'read_again' up to fix the count limit check.

The RX max frame size is over 10000 for the Gemini ethernet,
but the TX max frame size is actually just 2047 (0x7ff after
checking the datasheet). Reflect this in what we offer to Linux,
cap the MTU at the TX max frame minus ethernet headers.
We delete the code disabling the hardware checksum for large
MTUs as netdev->mtu can no longer be larger than
netdev->max_mtu meaning the if()-clause in gmac_fix_features()
is never true.

The Gemini ethernet controller provides hardware checksumming
for frames up to 1514 bytes including ethernet headers but not
FCS.
If we start sending bigger frames (after first bumping up the MTU
on both interfaces sending and receiving the frames), truncated
packets start to appear on the target such as in this tcpdump
resulting from ping -s 1474:
23:34:17.241983 14:d6:4d:a8:3c:4f (oui Unknown) > bc:ae:c5:6b:a8:3d (oui Unknown),
ethertype IPv4 (0x0800), length 1514: truncated-ip - 2 bytes missing!
(tos 0x0, ttl 64, id 32653, offset 0, flags [DF], proto ICMP (1), length 1502)
OpenWrt.lan > Fecusia: ICMP echo request, id 1672, seq 50, length 1482
If we bypass the hardware checksumming and provide a software
fallback, everything starts working fine up to the max TX MTU
of 2047 bytes, for example ping -s2000 192.168.1.2:
00:44:29.587598 bc:ae:c5:6b:a8:3d (oui Unknown) > 14:d6:4d:a8:3c:4f (oui Unknown),
ethertype IPv4 (0x0800), length 2042:
(tos 0x0, ttl 64, id 51828, offset 0, flags [none], proto ICMP (1), length 2028)
Fecusia > OpenWrt.lan: ICMP echo reply, id 1683, seq 4, length 2008
The bit enabling to bypass hardware checksum (or any of the
"TSS" bits) are undocumented in the hardware reference manual.
The entire hardware checksum unit appears undocumented. The
conclusion that we need to use the "bypass" bit was found by
trial-and-error.
Since no hardware checksum will happen, we slot in a software
checksum fallback.
Check for the condition where we need to compute checksum on the
skb with either hardware or software using == CHECKSUM_PARTIAL instead
of != CHECKSUM_NONE which is an incomplete check according to
<linux/skbuff.h>.
On the D-Link DIR-685 router this fixes a bug on the conduit
interface to the RTL8366RB DSA switch: as the switch needs to add
space for its tag it increases the MTU on the conduit interface
to 1504 and that means that when the router sends packages
of 1500 bytes these get an extra 4 bytes of DSA tag and the
transfer fails because of the erroneous hardware checksumming,
affecting such basic functionality as the LuCI web interface.

If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode
when PF queries the port information from firmware.
After imp reset command is executed, PF status changes to down,
and PF will query link status and updates port information
from firmware in a periodic scheduled task.
However, there is a low probability that port information is updated
when PF is down, and then PF link status changes to up.
In this case, PF synchronizes incorrect rate and duplex mode to VF.
This patch fixes it by updating port information before
PF synchronizes the rate and duplex to the VF
when PF changes to up.

In ppp_generic.c, memdup_user() is utilized to copy a userspace array.
This is done without an overflow-check, which is, however, not critical
because the multiplicands are an unsigned short and struct sock_filter,
which is currently of size 8.
Regardless, string.h now provides memdup_array_user(), a wrapper for
copying userspace arrays in a standardized manner, which has the
advantage of making it more obvious to the reader that an array is being
copied.
The wrapper additionally performs an obligatory overflow check, saving
the reader the effort of analyzing the potential for overflow, and
making the code a bit more robust in case of future changes to the
multiplicands len * size.
Replace memdup_user() with memdup_array_user().

NETLINK_MAX_FMTMSG_LEN is currently hardcoded to 80, and we provide an
error printf-formatted string having 96 characters including the
terminating \0. Assuming each %d (representing a queue) gets replaced by
a number having at most 2 digits (a reasonable assumption), the final
string is also 96 characters wide, which is too much.
Reduce the verbiage a bit by removing some (partially) redundant words,
which makes the new printf-formatted string be 73 characters wide with
the trailing newline.

Background: Turris Omnia (Armada 385); eth2 (mvneta) connected to SFP bus;
SFP module is present, but no fiber connected, so definitely no carrier.
After booting, eth2 is down, but netdev LED trigger surprisingly reports
link active. Then, after "ip link set eth2 up", the link indicator goes
away - as I would have expected it from the beginning.
It turns out, that the default carrier state after netdev creation is
"carrier ok". Some ethernet drivers explicitly call netif_carrier_off
during probing, others (like mvneta) don't - which explains the current
behaviour: only when the device is brought up, phylink_start calls
netif_carrier_off.
Fix this for all drivers using phylink, by calling netif_carrier_off in
phylink_create.

The TX ring maintained by the tg3 driver can end up in the state, when it
has packets queued for sending but the NIC hardware is not informed, so no
progress is made. This leads to a multi-second interruption in network
traffic followed by dev_watchdog() firing and resetting the queue.
The specific sequence of steps is:
1. tg3_start_xmit() is called at least once and queues packet(s) without
updating tnapi->prodmbox (netdev_xmit_more() returns true)
2. tg3_start_xmit() is called with an SKB which causes tg3_tso_bug() to be
called.
3. tg3_tso_bug() determines that the SKB is too large, ...
if (unlikely(tg3_tx_avail(tnapi) <= frag_cnt_est)) {
... stops the queue, and returns NETDEV_TX_BUSY:
netif_tx_stop_queue(txq);
...
if (tg3_tx_avail(tnapi) <= frag_cnt_est)
return NETDEV_TX_BUSY;
4. Since all tg3_tso_bug() call sites directly return, the code updating
tnapi->prodmbox is skipped.
5. The queue is stuck now. tg3_start_xmit() is not called while the queue
is stopped. The NIC is not processing new packets because
tnapi->prodmbox wasn't updated. tg3_tx() is not called by
tg3_poll_work() because the all TX descriptions that could be freed has
been freed:
/* run TX completion thread */
if (tnapi->hw_status->idx[0].tx_consumer != tnapi->tx_cons) {
tg3_tx(tnapi);
6. Eventually, dev_watchdog() fires triggering a reset of the queue.
This fix makes sure that the tnapi->prodmbox update happens regardless of
the reason tg3_start_xmit() returned.

When adding a drop rule on a VF, rule direction is not being set, which
results in it always being set to ingress (ICE_ESWITCH_FLTR_INGRESS

To fix it, set rule direction in drop action to egress when netdev is a

the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.
Another patch set by Geert Uytterhoeven revives SuperH BIOS
earlyprintk support which got accidentally disabled in
e76fe57447 ("sh: Remove old early serial console code V2"), the
second patch in the series updates the documentation.
Finally, a patch by Masami Hiramatsu fixes a regression reported by
the kernel test robot which uncovered that arch/sh is not implementing
arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
instead"

To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove
the sentinel. Both arch and driver changes have been on linux-next for a bit
less than a month. It is worth re-iterating the value:
- this helps reduce the overall build time size of the kernel and run time
memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move sysctls
out from kernel/sysctl.c to their own files
For v6.8-rc1 expect removal of all the sentinels and also then the unneeded
check for procname == NULL.
The last 2 patches are fixes recently merged by Krister Johansen which allow
us again to use softlockup_panic early on boot. This used to work but the
alias work broke it. This is useful for folks who want to detect softlockups
super early rather than wait and spend money on cloud solutions with nothing
but an eventual hung kernel. Although this hadn't gone through linux-next it's
also a stable fix, so we might as well roll through the fixes now.

The iavf client interface was added in 2017 by commit ed0e894de7
("i40evf: add client interface"), but there have never been any in-tree
callers.
It's not useful for future development either. The Intel out-of-tree
iavf and irdma drivers instead use an auxiliary bus, which is a better
solution.
Remove the iavf client interface code. Also gone are the client_task
work and the client_lock mutex.

Every time I create VFs on ice, I receive at least one "Device is still
in reset (-16), retrying" message per VF. It recovers fine, but typical
usecases should not trigger scary-looking messages.
The waiting for reset is too short. It makes no sense to check every 10
microseconds. Typical reset waiting times are at least tens of
milliseconds and can be several seconds. I suspect the polling interval
was meant to be 10 milliseconds all along.
IAVF_RESET_WAIT_COMPLETE_COUNT is defined as 2000, so the total waiting
time could be over 20 seconds. I have seen resets take 5 seconds (with
128 VFs on ice).
The added benefit of not triggering the "Device is still in reset" path
is that we avoid going through the __IAVF_INIT_FAILED state, which would
take a full second before retrying.

This pattern appears in two places in the iavf source code:
while (!mutex_trylock(...))
usleep_range(...);
That's just mutex_lock with extra steps.
The pattern is a leftover from when iavf used bit flags instead of
mutexes for locking. Commit 5ac49f3c27 ("iavf: use mutexes for locking
of critical sections") replaced test_and_set_bit with !mutex_trylock,
preserving the pattern.
Simplify it to mutex_lock.

Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound()
increment dev->stats.tx_errors in case of errors.
Unfortunately there are two issues :
1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user.
2) Increments are not atomic. KCSAN would complain eventually.
Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64()
to copy the value back to user.

Like other buses, devices on the netdevsim bus have a release callback
that is invoked when the reference count of the device drops to zero.
However, unlike other buses such as PCI, the release callback is not
necessarily built into the kernel, as netdevsim can be built as a
module.
The above is problematic as nothing prevents the module from being
unloaded before the release callback has been invoked, which can happen
asynchronously. One such example can be found in commit a380687200
("devlink: take device reference for devlink object") where devlink
calls put_device() from an RCU callback.
The issue is not theoretical and the reproducer in [1] can reliably
crash the kernel. The conclusion of this discussion was that the issue
should be solved in netdevsim, which is what this patch is trying to do.
Add a reference count that is increased when a device is added to the
bus and decreased when a device is released. Signal a completion when
the reference count drops to zero and wait for the completion when
unloading the module so that the module will not be unloaded before all
the devices were released. The reference count is initialized to one so
that completion is only signaled when unloading the module.
With this patch, the reproducer in [1] no longer crashes the kernel.

Introduce Wake on Magic Packet (WoL) functionality to the ksz9477
driver.
Major changes include:
1. Extending the `ksz9477_handle_wake_reason` function to identify Magic
Packet wake events alongside existing wake reasons.
2. Updating the `ksz9477_get_wol` and `ksz9477_set_wol` functions to
handle WAKE_MAGIC alongside the existing WAKE_PHY option, and to
program the switch's MAC address register accordingly when Magic
Packet wake-up is enabled. This change will prevent WAKE_MAGIC
activation if the related port has a different MAC address compared
to a MAC address already used by HSR or an already active WAKE_MAGIC
on another port.
3. Adding a restriction in `ksz_port_set_mac_address` to prevent MAC
address changes on ports with active Wake on Magic Packet, as the
switch's MAC address register is utilized for this feature.
