Using the syzkaller repro with reduced packet size it was discovered
that XDP_PACKET_HEADROOM is not checked in tun_can_build_skb(),
although pad may be incremented in tun_build_skb(). This may end up
with exceeding the PAGE_SIZE limit in tun_build_skb().
Jason Wang <jasowang@redhat.com> proposed to count XDP_PACKET_HEADROOM
always (e.g. without rcu_access_pointer(tun->xdp_prog)) in
tun_can_build_skb() since there's a window during which XDP program
might be attached between tun_can_build_skb() and tun_build_skb().

While performing certain power-off sequences, PCI drivers are called to
suspend and resume their underlying devices through PCI PM (power
management) interface. However the hardware does not support PCI PM
suspend/resume operations so system wide suspend/resume leads to bad MFW
(management firmware) state which causes various follow-up errors in driver
when communicating with the device/firmware.
To fix this driver implements PCI PM suspend handler to indicate
unsupported operation to the PCI subsystem explicitly, thus avoiding system
to go into suspended/standby mode.

As &qedi_percpu->p_work_lock is acquired by hard IRQ qedi_msix_handler(),
other acquisitions of the same lock under process context should disable
IRQ, otherwise deadlock could happen if the IRQ preempts the execution
while the lock is held in process context on the same CPU.
qedi_cpu_offline() is one such function which acquires the lock in process
context.
[Deadlock Scenario]
qedi_cpu_offline()
->spin_lock(&p->p_work_lock)
<irq>
->qedi_msix_handler()
->edi_process_completions()
->spin_lock_irqsave(&p->p_work_lock, flags); (deadlock here)
This flaw was found by an experimental static analysis tool I am developing
for IRQ-related deadlocks.
The tentative patch fix the potential deadlock by spin_lock_irqsave()
under process context.

When preparing protection DIF I/O for DMA, the driver obtains reference
tags from scsi_prot_ref_tag(). Previously, there was a wrong assumption
that an all 0xffffffff value meant error and thus the driver failed the
I/O. This patch removes the evaluation code and accepts whatever the upper
layer returns.

Pull xen netback buffer overflow fix from Juergen Gross:
"The fix for XSA-423 added logic to Linux'es netback driver to deal
with a frontend splitting a packet in a way such that not all of the
headers would come in one piece.
Unfortunately the logic introduced there didn't account for the
extreme case of the entire packet being split into as many pieces as
permitted by the protocol, yet still being smaller than the area
that's specially dealt with to keep all (possible) headers together.
Such an unusual packet would therefore trigger a buffer overrun in the
driver"

When we have multiple CPU DAIs in a dailink, typically for SoundWire
aggregated solutions with amplifiers on multiple links, we only want
to allocate one HDaudio stream_tag. The simplest solution is to
allocate the hext_stream/stream_tag for the DAI with index 0 in the
dailink, and reuse the same stream for all other CPU DAIs.
This assumption relies on serialization of DAIs by the ASoC core,
where all CPU DAIs are handled in a loop.
The stream release follows the same idea of releasing the tag for the
first DAI only. Ideally we would want the loop to be handled in
reverse-order to summetry, but there is no risk of reusing a
stream_tag which is no longer valid.

In the LunarLake hardware, the default IP ownership changed to the
host driver, instead of the firmware in previous generation.
In the absence of any capability negotiation, we need to assume a
fixed partitioning between host driver and firmware. The OFLEN bit
needs to be set as early as possible for resources handled by the
firmware, since we can't control when the firmware might try to access
the resources.
For now DMIC and SSP are handled by the DSP firmware. SoundWire is a
separate case, the OFLEN bit can be set when starting-up and resuming
the aux device for each link.

In the allowedips self-test, nodes are inserted into the tree, but it
generated an even amount of nodes, but for checking maximum node depth,
there is of course the root node, which makes the total number
necessarily odd. With two few nodes added, it never triggered the
maximum depth check like it should have. So, add 129 nodes instead of

BUG_ON(!vlan_info) is triggered in unregister_vlan_dev() with
following testcase:
# ip netns add ns1
# ip netns exec ns1 ip link add bond0 type bond mode 0
# ip netns exec ns1 ip link add bond_slave_1 type veth peer veth2
# ip netns exec ns1 ip link set bond_slave_1 master bond0
# ip netns exec ns1 ip link add link bond_slave_1 name vlan10 type vlan id 10 protocol 802.1ad
# ip netns exec ns1 ip link add link bond0 name bond0_vlan10 type vlan id 10 protocol 802.1ad
# ip netns exec ns1 ip link set bond_slave_1 nomaster
# ip netns del ns1
The logical analysis of the problem is as follows:
1. create ETH_P_8021AD protocol vlan10 for bond_slave_1:
register_vlan_dev()
vlan_vid_add()
vlan_info_alloc()
__vlan_vid_add() // add [ETH_P_8021AD, 10] vid to bond_slave_1
2. create ETH_P_8021AD protocol bond0_vlan10 for bond0:
register_vlan_dev()
vlan_vid_add()
__vlan_vid_add()
vlan_add_rx_filter_info()
if (!vlan_hw_filter_capable(dev, proto)) // condition established because bond0 without NETIF_F_HW_VLAN_STAG_FILTER
return 0;
if (netif_device_present(dev))
return dev->netdev_ops->ndo_vlan_rx_add_vid(dev, proto, vid); // will be never called
// The slaves of bond0 will not refer to the [ETH_P_8021AD, 10] vid.
3. detach bond_slave_1 from bond0:
__bond_release_one()
vlan_vids_del_by_dev()
list_for_each_entry(vid_info, &vlan_info->vid_list, list)
vlan_vid_del(dev, vid_info->proto, vid_info->vid);
// bond_slave_1 [ETH_P_8021AD, 10] vid will be deleted.
// bond_slave_1->vlan_info will be assigned NULL.
4. delete vlan10 during delete ns1:
default_device_exit_batch()
dev->rtnl_link_ops->dellink() // unregister_vlan_dev() for vlan10
vlan_info = rtnl_dereference(real_dev->vlan_info); // real_dev of vlan10 is bond_slave_1
BUG_ON(!vlan_info); // bond_slave_1->vlan_info is NULL now, bug is triggered!!!
Add S-VLAN tag related features support to bond driver. So the bond driver
will always propagate the VLAN info to its slaves.

If SNDRV_PCM_IOCTL_PREPARE is called when the mixer settings linking
frontend and backend have not been setup yet this results in
e.g. the following errors getting logged:
[ 43.244549] Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port
[ 43.244744] Baytrail Audio Port: ASoC: error at dpcm_fe_dai_prepare on Baytrail Audio Port: -22
pipewire triggers this leading to 96 lines getting logged
after the user has logged into a GNOME session.
Change the actual "no backend DAIs enabled for ... Port" error to
dev_err_once() to avoid it getting repeated 48 times. While at it
also improve the error by hinting the user how to fix this.
To not make developing new UCM profiles harder, also log the error
at dev_dbg() level all the time (vs once). So that e.g. dyndbg can
be used to (re)enable the messages.
Also changes _soc_pcm_ret() to not log for -EINVAL errors, to fix
the other error getting logged 48 times. Userspace passing wrong
parameters should not lead to dmesg messages.

Merge series from Alper Nebi Yasak <alpernebiyasak@gmail.com>:
This patchset adds missing jack kcontrols for each independently
detectable audio peripheral and maps jack pins to those kcontrols
accordingly, with the primary intent to enable/improve jack detection
handling in PulseAudio and PipeWire through JackControl UCM values.
Usually it's just splitting a joint anything-is-connected "Headset Jack"
kcontrol (from [1]) into those like "Headphone Jack" and "Headset Mic"
(similar to a previous series for Intel Chromebooks [2]). This split is
important to avoid automatically switching to a nonexistent external
microphone when a headphone-only device is connected.
When the underlying hardware seems to support it, this also adds a "Line
Out" kcontrol. This is important in case the hardware can actually
support a line-level connection via a different configuration (bypassing
output amplifiers?), or simply for userspace to display "Line Out"
instead of "Headphones" to the user for connected line-out devices.
Beyond the mappings, I had to add PIN_SWITCH card kcontrols and DAPM
widgets to avoid "unknown pin" errors on my devices, so tried to do them
for all. For Intel devices I saw a pattern of routing things to
"Platform Clock" and added to that as well. Looking at patch 5/7 of a
Mediatek-related series [3], I can only guess that routes could be
further improved, but don't know exactly how for each device. And one
more concern is I don't know if the names conflict with any controls
from codecs, although I tried to keep to names of existing widgets.
As far as I can tell, the root cause for most of why these are missing
originates to things being developed for ChromeOS, whose userspace reads
the jack input device and doesn't care for these kcontrols. There's
non-ChromeOS cases as well, maybe things got copy-pasted around and
people didn't need or couldn't figure out how to get more specific than
a single jack kcontrol. The secondary intent in this patchset is to fix
this *everywhere*, so future copy-pastes result in the right behaviour.
For more context also see:

This applies onto next-20230802. Unfortunately most of it is untested
except for a few Chromebooks I have (Kevin, Lick, Hana, Cozmo), because
I'm intentionally generalizing to everything.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This patchset improves the pm_runtime behavior in rare corner cases
identified by the Intel CI in the last 6 months.
a) in stress-tests, it's not uncommon to see the following type of
warnings when the codec reports as ATTACHED
"rt711 sdw:0:025d:0711:00: runtime PM trying to activate child device
sdw:0:025d:0711:00 but parent (sdw-master-0) is not active"
This warning was not correlated with any functional issue, but it
exposed a design issue on when to enable pm_runtime. The recommended
practice in the pm_runtime documentation is to keep the devices in
'suspended' mode and mark them as 'active' when they are really
functional.
b) enabling pm_runtime when the codec reports as ATTACHED also creates
a problematic case when the ASoC pm_runtime_get_sync() will silently
fail due to the -EACCESS error handling. This can happen when playback
starts before the codec is enumerated.
This patchset modifies the initial stages so that codecs are
pm_runtime enabled in the .probe() callback, but become pm_runtime
'active' only when they report present. This is better aligned with
the design of the pm_runtime helpers and improved CI results
significantly.
This patchset modifies all existing SoundWire codecs (except Qualcomm
ones), but the pattern of changes is exactly the same in all patches.
