ASoC: SOF: ipc4-pcm: Introduce generic sof_ipc4_pcm_stream_priv
Using the sof_ipc4_timestamp_info struct directly as sps->private data
is too restrictive, add a new generic sof_ipc4_pcm_stream_priv struct
containing the time_info to allow new information to be stored in a
generic way.

166a490f59 wifi: ath11k: support hibernation
Now that all infrastructure is in place and ath11k is fixed to handle all the
corner cases, power down the ath11k firmware during suspend and power it back
up during resume. This fixes the problem when using hibernation with ath11k PCI
devices.

For suspend, two conditions needs to be satisfied:
        1. since MHI channel unprepare would be done in late suspend stage,
           ath11k needs to get all QMI-dependent things done before that stage.
        2. and because unprepare MHI channels requires a working MHI stack,
           ath11k is not allowed to call mhi_power_down() until that finishes.
So the original suspend callback is separated into two parts: the first part
handles all QMI-dependent things in suspend callback; while the second part
powers down MHI in suspend_late callback. This is valid because kernel calls
ath11k's suspend callback before all suspend_late callbacks, making the first
condition happy. And because MHI devices are children of ath11k device
(ab->dev), kernel guarantees that ath11k's suspend_late callback is called
after QRTR's suspend_late callback, this satisfies the second condition.

Above analysis also applies to resume process. so the original resume
callback is separated into two parts: the first part powers up MHI stack
in resume_early callback, this guarantees MHI stack is working when
QRTR tries to prepare MHI channels (kernel calls QRTR's resume_early callback
after ath11k's resume_early callback, due to the child-father relationship);
the second part waits for the completion of restart, which won't fail now
since MHI channels are ready for use by QMI.

Another notable change is in power down path, we tell mhi_power_down() to not
to destroy MHI devices, making it possible for QRTR to help unprepare/prepare
MHI channels, and finally get us rid of the probe-defer issue when resume.

Also change related code due to interface changes.

e0cd118590 net: qrtr: support suspend/hibernation
MHI devices may not be destroyed during suspend/hibernation, so need
to unprepare/prepare MHI channels throughout the transition, this is
done by adding suspend/resume callbacks.

The suspend callback is called in the late suspend stage, this means
MHI channels are still alive at suspend stage, and that makes it
possible for an MHI controller driver to communicate with others over
those channels at suspend stage. While the resume callback is called
in the early resume stage, for a similar reason.

Also note that we won't do unprepare/prepare when MHI device is in
suspend state because it's pointless if MHI is only meant to go through
a suspend/resume transition, instead of a complete power cycle.

9e63941b89 net: phy: micrel: lan8814: Add support for PTP_PF_PEROUT
Lan8814 has 24 GPIOs but only 2 GPIOs (GPIO 0 and GPIO 1) can be
configured to generate period signals. And there are 2 events (EVENT_A
and EVENT_B) but these events are hardcoded to the GPIO 0 and GPIO 1.
These events are used to generate period signals. It is possible to
configure the length, the start time and the period of the signal by
configuring the event.

These events are generated by comparing the target time with the PHC
time. In case the PHC time is changed to a value bigger than the target
time + reload time, then it would generate only 1 event and then it
would stop because target time + reload time is smaller than PHC time.
Therefore it is required to change also the target time every time when
the PHC is changed. The same will apply also when the PHC time is
changed to a smaller value.

This was tested using:
testptp -i 1 -L 1,2
testptp -i 1 -p 1000000000 -w 200000000

The LTC for lan8814 was enabled only if timestamping was enabled,
otherwise it would be stopped. Meaning that LTC will not increase by
itself. This might break other features that don't required timestamping

734554fdfc iommu/arm-smmu-v3: Retire disable_bypass parameter
The disable_bypass parameter has been mostly meaningless for a long time
since the introduction of default domains. Its original intent is now
fulfilled by the controls users have over the default domain type, and
its remaining effect in the brief window between Stream Table
initialisation and default domain creation hardly seems worth the
complication. Furthermore, thanks to 2-level Stream Tables, disabling
disable_bypass (there's another reason not to like it right there) has
never guaranteed that any particular StreamID *will* bypass anyway - any
device which might actually care about that wants RMRs - so there's not
really much lost by taking away that option (which has already been
non-default for nearing 6 years now).

As part of this, also remove the weird behaviour where we "successfully"
probe and register a non-functional SMMU if the DT "#iommu-cells"
property is wrong. I have no memory of what possessed me to think that
was a good idea at the time, and by now I suspect it's likely to break
things worse than simply failing probe would.

fs: Return ENOTTY directly if FS_IOC_GETUUID or FS_IOC_GETFSSYSFSPATH fail
These IOCTL commands should be implemented by setting attributes on the
superblock, rather than in the IOCTL hooks in struct file_operations.

By returning -ENOTTY instead of -ENOIOCTLCMD, we instruct the fs/ioctl.c
logic to return -ENOTTY immediately, rather than attempting to call
f_op->unlocked_ioctl() or f_op->compat_ioctl() as a fallback.

Why this is safe:

Before this change, fs/ioctl.c would unsuccessfully attempt calling the
IOCTL hooks, and then return -ENOTTY.  By returning -ENOTTY directly, we
return the same error code immediately, but save ourselves the fallback
attempt.

Motivation:

This simplifies the logic for these IOCTL commands and lets us reason about
the side effects of these IOCTLs more easily.  It will be possible to
permit these IOCTLs under LSM IOCTL policies, without having to worry about
them getting dispatched to problematic device drivers (which sometimes do
work before looking at the IOCTL command number).

d2fd6cf39a Merge branch 'tcp-fix-isn-selection-in-timewait-syn_recv'
Eric Dumazet says:

====================
tcp: fix ISN selection in TIMEWAIT -> SYN_RECV

TCP can transform a TIMEWAIT socket into a SYN_RECV one from
a SYN packet, and the ISN of the SYNACK packet is normally
generated using TIMEWAIT tw_snd_nxt.

This SYN packet also bypasses normal checks against listen queue
being full or not.

Unfortunately this has been broken almost one decade ago.

This series fixes the issue, in two patches.

First patch refactors code to add tcp_tw_isn as a parameter
to ->route_req(), to make the second patch smaller.

Second patch fixes the issue, by no longer using TCP_SKB_CB(skb)
to store the tcp_tw_isn.

Following packetdrill test passes after this series:

// Set up a server listening socket.
    0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
   +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0

41eecbd712 tcp: replace TCP_SKB_CB(skb)->tcp_tw_isn with a per-cpu field
TCP can transform a TIMEWAIT socket into a SYN_RECV one from
a SYN packet, and the ISN of the SYNACK packet is normally
generated using TIMEWAIT tw_snd_nxt :

tcp_timewait_state_process()
...
    u32 isn = tcptw->tw_snd_nxt + 65535 + 2;
    if (isn == 0)
        isn++;
    TCP_SKB_CB(skb)->tcp_tw_isn = isn;
    return TCP_TW_SYN;

This SYN packet also bypasses normal checks against listen queue
being full or not.

tcp_conn_request()
...
       __u32 isn = TCP_SKB_CB(skb)->tcp_tw_isn;
...
        /* TW buckets are converted to open requests without
         * limitations, they conserve resources and peer is
         * evidently real one.
         */
        if ((syncookies == 2 || inet_csk_reqsk_queue_is_full(sk)) && !isn) {
                want_cookie = tcp_syn_flood_action(sk, rsk_ops->slab_name);
                if (!want_cookie)
                        goto drop;
        }

This was using TCP_SKB_CB(skb)->tcp_tw_isn field in skb.

Unfortunately this field has been accidentally cleared
after the call to tcp_timewait_state_process() returning
TCP_TW_SYN.

Using a field in TCP_SKB_CB(skb) for a temporary state
is overkill.

Switch instead to a per-cpu variable.

As a bonus, we do not have to clear tcp_tw_isn in TCP receive
fast path.
It is temporarily set then cleared only in the TCP_TW_SYN dance.

b9e8104058 tcp: propagate tcp_tw_isn via an extra parameter to ->route_req()
tcp_v6_init_req() reads TCP_SKB_CB(skb)->tcp_tw_isn to find
out if the request socket is created by a SYN hitting a TIMEWAIT socket.

This has been buggy for a decade, lets directly pass the information
from tcp_conn_request().

This is a preparatory patch to make the following one easier to review.

80e9963fb3 irqchip/gic-v3-its: Fix VSYNC referencing an unmapped VPE on GIC v4.1
As per the GICv4.1 spec (Arm IHI 0069H, 5.3.19):

 "A VMAPP with {V, Alloc}=={0, x} is self-synchronizing, This means the ITS
  command queue does not show the command as consumed until all of its
  effects are completed."

Furthermore, VSYNC is allowed to deliver an SError when referencing a
non existent VPE.

By these definitions, a VMAPP followed by a VSYNC is a bug, as the
later references a VPE that has been unmapped by the former.

Fix it by eliding the VSYNC in this scenario.

orangefs: cleanup uses of strncpy
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

There is some care taken to ensure these destination buffers are
NUL-terminated by bounding the strncpy()'s by ORANGEFS_NAME_MAX - 1 or
ORANGEFS_MAX_SERVER_ADDR_LEN - 1. Instead, we can use the new 2-argument
version of strscpy() to guarantee NUL-termination on the destination
buffers while simplifying the code.

Based on usage with printf-likes, we can see these buffers are expected
to be NUL-terminated:
|	gossip_debug(GOSSIP_NAME_DEBUG,
|			"%s: doing lookup on %s under %pU,%d\n",
|			__func__,
|			new_op->upcall.req.lookup.d_name,
|			&new_op->upcall.req.lookup.parent_refn.khandle,
|			new_op->upcall.req.lookup.parent_refn.fs_id);
...
|	gossip_debug(GOSSIP_SUPER_DEBUG,
|			"Attempting ORANGEFS Remount via host %s\n",
|			new_op->upcall.req.fs_mount.orangefs_config_server);

NUL-padding isn't required for any of these destination buffers as
they've all been zero-allocated with op_alloc() or kzalloc().

Daniel Machon says:

====================
Add support for flower actions mirred and redirect

This series adds support for the two tc flower actions mirred and
redirect. Both actions are implemented by means of a port mask and a
mask mode. The mask mode controls how the mask is applied, and together
they are used by the switch to make a forwarding decision. Both actions
are configurable via the IS0 or IS2 VCAP's (ingress stage 0 and 2,
respectively).

Patch #1: adds support for tc flower mirred action.
Patch #2: adds support for tc flower redirect action.
