As part of the commit b148bb238c02
("bnxt_en: Fix possible crash in bnxt_fw_reset_task()."),
cancel_delayed_work_sync() is called only for VFs to fix a possible
crash by cancelling any pending delayed work items. It was assumed
by mistake that the flush_workqueue() call on the PF would flush
delayed work items as well.
As flush_workqueue() does not cancel the delayed workqueue, extend
the fix for PFs. This fix will avoid the system crash, if there are
any pending delayed work items in fw_reset_task() during driver's
.remove() call.
Unify the workqueue cleanup logic for both PF and VF by calling
cancel_work_sync() and cancel_delayed_work_sync() directly in
bnxt_remove_one().

A recent patch has moved the workqueue cleanup logic before
calling unregister_netdev() in bnxt_remove_one(). This caused a
regression because the workqueue can be restarted if the device is
still open. Workqueue cleanup must be done after unregister_netdev().
The workqueue will not restart itself after the device is closed.
Call bnxt_cancel_sp_work() after unregister_netdev() and
call bnxt_dl_fw_reporters_destroy() after that. This fixes the
regession and the original NULL ptr dereference issue.

Each EMAD transaction stores the skb used to issue the EMAD request
('trans->tx_skb') so that the request could be retried in case of a
timeout. The skb can be freed when a corresponding response is received
or as part of the retry logic (e.g., failed retransmit, exceeded maximum
number of retries).
The two tasks (i.e., response processing and retransmits) are
synchronized by the atomic 'trans->active' field which ensures that
responses to inactive transactions are ignored.
In case of a failed retransmit the transaction is finished and all of
its resources are freed. However, the current code does not mark it as
inactive. Syzkaller was able to hit a race condition in which a
concurrent response is processed while the transaction's resources are
being freed, resulting in a use-after-free [1].
Fix the issue by making sure to mark the transaction as inactive after a
failed retransmit and free its resources only if a concurrent task did
not already do that.

During port creation the driver instructs the device to advertise all
the supported link modes queried from the device.
Since cited commit not all the link modes supported by the device are
supported by the driver. This can result in the device negotiating a
link mode that is not recognized by the driver causing ethtool to show
an unsupported speed:
$ ethtool swp1
...
Speed: Unknown!
This is especially problematic when the netdev is enslaved to a bond, as
the bond driver uses unknown speed as an indication that the link is
down:
[13048.900895] net_ratelimit: 86 callbacks suppressed
[13048.900902] t_bond0: (slave swp52): failed to get link speed/duplex
[13048.912160] t_bond0: (slave swp49): failed to get link speed/duplex
Fix this by making sure that only link modes that are supported by both
the device and the driver are advertised.

The code to try to shut up sparse warnings about questionable locking
didn't shut up sparse: it made the result not parse as valid C at all,
since the end result now has a label with no statement.
The proper fix is to just always lock the hardware, the same way Bart
did in commit 8ae178760b23 ("scsi: qla2xxx: Simplify the functions for
dumping firmware"). That avoids the whole problem with having locking
that is not statically obvious.
But in the meantime, just remove the incorrect attempt at trying to
avoid a sparse warning that just made things worse.
This was exposed by commit 3e6efab865ac ("scsi: qla2xxx: Fix reset of
MPI firmware"), very similarly to how commit cbb01c2f2f63 ("scsi:
qla2xxx: Fix MPI failure AEN (8200) handling") exposed the same problem
in another place, and caused that commit 8ae178760b23.
Please don't add code to just shut up sparse without actually fixing
what sparse complains about.

When a mlx5 core devlink instance is reloaded in different net namespace,
its associated IB device is deleted and recreated.
Example sequence is:
$ ip netns add foo
$ devlink dev reload pci/0000:00:08.0 netns foo
$ ip netns del foo
mlx5 IB device needs to attach and detach the netdevice to it through the
netdev notifier chain during load and unload sequence. A below call graph
of the unload flow.
cleanup_net()
down_read(&pernet_ops_rwsem); <- first sem acquired
ops_pre_exit_list()
pre_exit()
devlink_pernet_pre_exit()
devlink_reload()
mlx5_devlink_reload_down()
mlx5_unload_one()
[...]
mlx5_ib_remove()
mlx5_ib_unbind_slave_port()
mlx5_remove_netdev_notifier()
unregister_netdevice_notifier()
down_write(&pernet_ops_rwsem);<- recurrsive lock
Hence, when net namespace is deleted, mlx5 reload results in deadlock.
When deadlock occurs, devlink mutex is also held. This not only deadlocks
the mlx5 device under reload, but all the processes which attempt to
access unrelated devlink devices are deadlocked.
Hence, fix this by mlx5 ib driver to register for per net netdev notifier
instead of global one, which operats on the net namespace without holding
the pernet_ops_rwsem.

This heavily degrades performance for v2 hw, since the HW queues are not

- Unify the kgdb_breakpoint() call
- Drop the non-existing CONFIG_HAVE_KGDB

ASSERT_CRITICAL() invokes kgdb_breakpoint() whenever either
CONFIG_KGDB or CONFIG_HAVE_KGDB is set. This, however, may lead to a
kernel panic when no kdb stuff is attached, since the
kgdb_breakpoint() call issues INT3. It's nothing but a surprise for
normal end-users.
For avoiding the pitfall, make the kgdb_breakpoint() call only when
CONFIG_DEBUG_KERNEL_DC is set.

Currently both error code paths handled in dal_gpio_open_ex() issues
ASSERT_CRITICAL(), and this leads to a kernel panic unnecessarily if
CONFIG_KGDB is enabled. Since basically both are non-critical errors
and can be recovered, drop those assert calls and use a safer one,
BREAK_TO_DEBUGGER(), for allowing the debugging, instead.

After a loss of transport due to an adapter migration or crash/disconnect
from the host partner there is a tiny window where we can race adjusting
the request_limit of the adapter. The request limit is atomically
increased/decreased to track the number of inflight requests against the
allowed limit of our VIOS partner.
After a transport loss we set the request_limit to zero to reflect this
state. However, there is a window where the adapter may attempt to queue a
command because the transport loss event hasn't been fully processed yet
and request_limit is still greater than zero. The hypercall to send the
event will fail and the error path will increment the request_limit as a
result. If the adapter processes the transport event prior to this
increment the request_limit becomes out of sync with the adapter state and
can result in SCSI commands being submitted on the now reset connection
prior to an SRP Login resulting in a protocol violation.
Fix this race by protecting request_limit with the host lock when changing
the value via atomic_set() to indicate no transport.

The current scanning mechanism is supposed to fall back to a synchronous
host scan if an asynchronous scan is in progress. However, this rule isn't
strictly respected, scsi_prep_async_scan() doesn't hold scan_mutex when
checking shost->async_scan. When scsi_scan_host() is called concurrently,
two async scans on same host can be started and a hang in do_scan_async()
is observed.
Fixes this issue by checking & setting shost->async_scan atomically with
shost->scan_mutex.

When using the scaler on the A10-like frontend with single-planar formats,
the current code will setup the channel 0 filter (used for the R or Y
component) with a different phase parameter than the channel 1 filter (used
for the G/B or U/V components).
This creates a bleed out that keeps repeating on of the last line of the
RGB plane across the rest of the display. The Allwinner BSP either applies
the same phase parameter over both channels or use a separate one, the
condition being whether the input format is YUV420 or not.
Since YUV420 is both subsampled and multi-planar, and since YUYV is
subsampled but single-planar, we can rule out the subsampling and assume
that the condition is actually whether the format is single or
multi-planar. And it looks like applying the same phase parameter over both
channels for single-planar formats fixes our issue, while we keep the
multi-planar formats working properly.

The scaler filter phase setup in the allwinner kernel has two different
cases for setting up the scaler filter, the first one using different phase
parameters for the two channels, and the second one reusing the first
channel parameters on the second channel.
The allwinner kernel has a third option where the horizontal phase of the
second channel will be set to a different value than the vertical one (and
seems like it's the same value than one used on the first channel).
However, that code path seems to never be taken, so we can ignore it for
now, and it's essentially what we're doing so far as well.
Since we will have always the same values across each components of the
filter setup for a given channel, we can simplify a bit our frontend
structure by only storing the phase value we want to apply to a given
channel.

The reserved-memory overlap detection code fails to detect overlaps if
either of the regions starts at address 0x0. The code explicitly checks
for and ignores such regions, apparently in order to ignore dynamically
allocated regions which have an address of 0x0 at this point. These
dynamically allocated regions also have a size of 0x0 at this point, so
fix this by removing the check and sorting the dynamically allocated
regions ahead of any static regions at address 0x0.
For example, there are two overlaps in this case but they are not
currently reported:
foo@0 {
reg = <0x0 0x2000>;
};
bar@0 {
reg = <0x0 0x1000>;
};
baz@1000 {
reg = <0x1000 0x1000>;
};
quux {
size = <0x1000>;
};
but they are after this patch:
OF: reserved mem: OVERLAP DETECTED!
bar@0 (0x00000000--0x00001000) overlaps with foo@0 (0x00000000--0x00002000)
OF: reserved mem: OVERLAP DETECTED!

"Make prandom_u32() less predictable.
This is the cleanup of the latest series of prandom_u32
experimentations consisting in using SipHash instead of Tausworthe to
produce the randoms used by the network stack.
The changes to the files were kept minimal, and the controversial
commit that used to take noise from the fast_pool (f227e3ec3b5c) was
reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
fed from various sources of activities (networking, scheduling) to
perturb the SipHash state using fast, non-trivially predictable data,
instead of keeping it fully deterministic. The goal is essentially to
make any occasional memory leakage or brute-force attempt useless.
The resulting code was verified to be very slightly faster on x86_64
than what is was with the controversial commit above, though this
remains barely above measurement noise. It was also tested on i386 and
arm, and build- tested only on arm64"

registering the ACPI i2c devs
Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.

Non-cryptographic PRNGs may have great statistical properties, but
are usually trivially predictable to someone who knows the algorithm,
given a small sample of their output. An LFSR like prandom_u32() is
particularly simple, even if the sample is widely scattered bits.
It turns out the network stack uses prandom_u32() for some things like
random port numbers which it would prefer are *not* trivially predictable.
Predictability led to a practical DNS spoofing attack. Oops.
This patch replaces the LFSR with a homebrew cryptographic PRNG based
on the SipHash round function, which is in turn seeded with 128 bits
of strong random key. (The authors of SipHash have *not* been consulted
about this abuse of their algorithm.) Speed is prioritized over security;
attacks are rare, while performance is always wanted.
Replacing all callers of prandom_u32() is the quick fix.
Whether to reinstate a weaker PRNG for uses which can tolerate it
is an open question.
Commit f227e3ec3b5c ("random32: update the net random state on interrupt
and activity") was an earlier attempt at a solution. This patch replaces
it.

platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"
