Pull ARM SoC fixes from Arnd Bergmann:
"There is a fairly large number of bug fixes for Qualcomm platforms,
most of them addressing issues with the devicetree files for the newly
added Snapdragon X1 based laptops to make them more reliable.
The Qualcomm driver changes address a few build-time issues as well as
runtime problems in the tzmem and scm firmware, the USB Type-C driver,
and the cmd-db and pmic_glink soc drivers.
The NXP i.MX usually gets a bunch of devicetree fixes that is
proportional to the number of supported machines. This includes both
warning fixes and correctness for the 64-bit i.MX9, i.MX8 and
layerscape platforms, as well as a single fix for a 32-bit i.MX6 based
board.
The other changes are the usual minor changes, including an update to
the MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs
(risc-v)"

Typically, busy-polling durations are below 100 usec.
When/if the busy-poller thread migrates to another cpu,
local_clock() can be off by +/-2msec or more for small
values of HZ, depending on the platform.
Use ktimer_get_ns() to ensure deterministic behavior,
which is the whole point of busy-polling.

Qualcomm driver fixes for v6.11
This corrects the tzmem virt-to-phys conversion, which caused issues for
the uefisecapp implementation of EFI variable access. SDM670 is excluded
from tzmem usage due to reported issues.
The SCM get wait queue context call is corrected to be marked ATOMIC and
some dead code in qseecom, following the tzmem conversion, is removed.
The memory backing command DB is remapped writecombined, to avoid XPU
violations when Linux runs without the Qualcomm hypervisor.
Two compile fixes are added for pd-mapper, and the broken reference
count is corrected, to make pd-mapper deal with remoteprocs going away.
In pmic_glink a race condition where the client callbacks might be
called before we returned the client handle is corrected. The broken conditions
for when to signal that the firmware is going down is also corrected.
In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the
pdr callback, as this is being invoked in atomic context.
Konrad's email address is updated in MAINTAINERS, and related mailmap
entries are added.

Short DIO reads, particularly in relation to cifs, are not being handled
correctly by cifs and netfslib. This can be tested by doing a DIO read of
a file where the size of read is larger than the size of the file. When it
crosses the EOF, it gets a short read and this gets retried, and in the
case of cifs, the retry read fails, with the failure being translated to
ENODATA.
Fix this by the following means:
(1) Add a flag, NETFS_SREQ_HIT_EOF, for the filesystem to set when it
detects that the read did hit the EOF.
(2) Make the netfslib read assessment stop processing subrequests when it
encounters one with that flag set.
(3) Return rreq->transferred, the accumulated contiguous amount read to
that point, to userspace for a DIO read.
(4) Make cifs set the flag and clear the error if the read RPC returned
ENODATA.
(5) Make cifs set the flag and clear the error if a short read occurred
without error and the read-to file position is now at the remote inode
size.

In the cited commit, bond->ipsec_lock is added to protect ipsec_list,
hence xdo_dev_state_add and xdo_dev_state_delete are called inside
this lock. As ipsec_lock is a spin lock and such xfrmdev ops may sleep,
"scheduling while atomic" will be triggered when changing bond's
active slave.

As bond_ipsec_add_sa_all and bond_ipsec_del_sa_all are only called
from bond_change_active_slave, which requires holding the RTNL lock.
And bond_ipsec_add_sa and bond_ipsec_del_sa are xfrm state
xdo_dev_state_add and xdo_dev_state_delete APIs, which are in user
context. So ipsec_lock doesn't have to be spin lock, change it to
mutex, and thus the above issue can be resolved.

ARL and MTL share a single GSC firmware blob. However, ARL requires a
newer version of it.
So add differentiate of the PCI ids for ARL from MTL and create ARL as
a sub-platform of MTL. That way, all the existing workarounds and such
still treat ARL as MTL exactly as before. However, now the GSC code
can check for ARL and do an extra version check on the firmware before
committing to it.
Also, the version extraction code has various ways of failing but the
return code was being ignore and so the firmware load would attempt to
continue anyway. Fix that by propagating the return code to the next
level out.

In aperture_remove_conflicting_pci_devices(), we currently only
call sysfb_disable() on vga class devices. This leads to the
following problem when the pimary device is not VGA compatible:
1. A PCI device with a non-VGA class is the boot display
2. That device is probed first and it is not a VGA device so
sysfb_disable() is not called, but the device resources
are freed by aperture_detach_platform_device()
3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable()
4. NULL pointer dereference via sysfb_disable() since the resources
have already been freed by aperture_detach_platform_device() when
it was called by the other device.
Fix this by passing a device pointer to sysfb_disable() and checking
the device to determine if we should execute it or not.

Currently, we copy the mtime and ctime to the in-core inode and then
mark the inode dirty. This is fine for certain types of filesystems, but
not all. Some require a real setattr to properly change these values
(e.g. ceph or reexported NFS).
Fix this code to call notify_change() instead, which is the proper way
to effect a setattr. There is one problem though:
In this case, the client is holding a write delegation and has sent us
attributes to update our cache. We don't want to break the delegation
for this since that would defeat the purpose. Add a new ATTR_DELEG flag
that makes notify_change bypass the try_break_deleg call.

Subtract network offset to skb->len before performing IPv4 header sanity
checks, then adjust transport offset from offset from mac header.
Jorge Ortiz says:
When small UDP packets (< 4 bytes payload) are sent from eth0,
`meta l4proto udp` condition is not met because `NFT_PKTINFO_L4PROTO` is
not set. This happens because there is a comparison that checks if the
transport header offset exceeds the total length. This comparison does
not take into account the fact that the skb network offset might be
non-zero in egress mode (e.g., 14 bytes for Ethernet header).

The iommu_report_device_fault function was updated to return void while
assuming that drivers only need to call iommu_report_device_fault() for
reporting an iopf. This implementation causes following problems:
1. The drivers rely on the core code to call it's page_reponse,
however, when a fault is received and no fault capable domain is
attached / iopf_param is NULL, the ops->page_response is NOT called
causing the device to stall in case the fault type was PAGE_REQ.
2. The arm_smmu_v3 driver relies on the returned value to log errors
returning void from iommu_report_device_fault causes these events to
be missed while logging.
Modify the iommu_report_device_fault function to return -EINVAL for
cases where no fault capable domain is attached or iopf_param was NULL
and calls back to the driver (ops->page_response) in case the fault type
was IOMMU_FAULT_PAGE_REQ. The returned value can be used by the drivers
to log the fault/event as needed.

As pointed out by Stephen Boyd it is possible that during initialization
of the pmic_glink child drivers, the protection-domain notifiers fires,
and the associated work is scheduled, before the client registration
returns and as a result the local "client" pointer has been initialized.
The outcome of this is a NULL pointer dereference as the "client"
pointer is blindly dereferenced.
Timeline provided by Stephen:
CPU0 CPU1
---- ----
ucsi->client = NULL;
devm_pmic_glink_register_client()
client->pdr_notify(client->priv, pg->client_state)
pmic_glink_ucsi_pdr_notify()
schedule_work(&ucsi->register_work)
<schedule away>
pmic_glink_ucsi_register()
ucsi_register()
pmic_glink_ucsi_read_version()
pmic_glink_ucsi_read()
pmic_glink_ucsi_read()
pmic_glink_send(ucsi->client)
<client is NULL BAD>
ucsi->client = client // Too late!
This code is identical across the altmode, battery manager and usci
child drivers.
Resolve this by splitting the allocation of the "client" object and the
registration thereof into two operations.
This only happens if the protection domain registry is populated at the
time of registration, which by the introduction of commit '1ebcde047c54
("soc: qcom: add pd-mapper implementation")' became much more likely.

syzkaller reported UAF in kcm_release(). [0]
The scenario is
1. Thread A builds a skb with MSG_MORE and sets kcm->seq_skb.
2. Thread A resumes building skb from kcm->seq_skb but is blocked
by sk_stream_wait_memory()
3. Thread B calls sendmsg() concurrently, finishes building kcm->seq_skb
and puts the skb to the write queue
4. Thread A faces an error and finally frees skb that is already in the
write queue
5. kcm_release() does double-free the skb in the write queue
When a thread is building a MSG_MORE skb, another thread must not touch it.
Let's add a per-sk mutex and serialise kcm_sendmsg().

Dell All In One (AIO) models released after 2017 use a backlight
controller board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Commit 484bae9e4d6a ("platform/x86: Add new Dell UART backlight driver")
has added support for this, but I neglected to tie this into
acpi_video_get_backlight_type().
Now the first AIO has turned up which has not only the DSDT bits for this,
but also an actual controller attached to the UART, yet it is not using
this controller for backlight control.
Add support to acpi_video_get_backlight_type() for a new dell_uart
backlight type. So that the existing infra to override the backlight
control method on the commandline or with DMI quirks can be used.

capabilities register
'Legacy Queue & Single Doorbell Support (LSDBS)' field in the controller
capabilities register is supposed to report whether the legacy single
doorbell mode is supported in the controller or not. But some controllers
report '1' in this field which corresponds to 'LSDB not supported', but
they indeed support LSDB. So let's add a quirk to handle those controllers.
If the quirk is enabled by the controller driver, then LSDBS register field
will be ignored and legacy single doorbell mode is assumed to be enabled
always.

After running once, the for_each_trip_desc() loop in
bang_bang_manage() is pure needless overhead because it is not going to
make any changes unless a new cooling device has been bound to one of
the trips in the thermal zone or the system is resuming from sleep.
For this reason, make bang_bang_manage() set governor_data for the
thermal zone and check it upfront to decide whether or not it needs to
do anything.
However, governor_data needs to be reset in some cases to let
bang_bang_manage() know that it should walk the trips again, so add an
.update_tz() callback to the governor and make the core additionally
invoke it during system resume.
To avoid affecting the other users of that callback unnecessarily, add
a special notification reason for system resume, THERMAL_TZ_RESUME, and
also pass it to __thermal_zone_device_update() called during system
resume for consistency.

I was revisiting the topic of 802.1ad treatment in the Ocelot switch [0]
and realized that not only is its basic VLAN classification pipeline
improper for offloading vlan_protocol 802.1ad bridges, but also improper
for offloading regular 802.1Q bridges already.
Namely, 802.1ad-tagged traffic should be treated as VLAN-untagged by
bridged ports, but this switch treats it as if it was 802.1Q-tagged with
the same VID as in the 802.1ad header. This is markedly different to
what the Linux bridge expects; see the "other_tpid()" function in
tools/testing/selftests/net/forwarding/bridge_vlan_aware.sh.
An idea came to me that the VCAP IS1 TCAM is more powerful than I'm
giving it credit for, and that it actually overwrites the classified VID
before the VLAN Table lookup takes place. In other words, it can be
used even to save a packet from being dropped on ingress due to VLAN
membership.
Add a sophisticated TCAM rule hardcoded into the driver to force the
switch to behave like a Linux bridge with vlan_filtering 1 vlan_protocol
802.1Q.
Regarding the lifetime of the filter: eventually the bridge will
disappear, and vlan_filtering on the port will be restored to 0 for
standalone mode. Then the filter will be deleted.

Through code analysis, I realized that the ds->untag_bridge_pvid logic
is contradictory - see the newly added FIXME above the kernel-doc for
dsa_software_untag_vlan_unaware_bridge().
Moreover, for the Felix driver, I need something very similar, but which
is actually _not_ contradictory: untag the bridge PVID on RX, but for
VLAN-aware bridges. The existing logic does it for VLAN-unaware bridges.
Since I don't want to change the functionality of drivers which were
supposedly properly tested with the ds->untag_bridge_pvid flag, I have
introduced a new one: ds->untag_vlan_aware_bridge_pvid, and I have
refactored the DSA reception code into a common path for both flags.
TODO: both flags should be unified under a single ds->software_vlan_untag,
which users of both current flags should set. This is not something that
can be carried out right away. It needs very careful examination of all
drivers which make use of this functionality, since some of them
actually get this wrong in the first place.
For example, commit 9130c2d30c17 ("net: dsa: microchip: ksz8795: Use
software untagging on CPU port") uses this in a driver which has
ds->configure_vlan_while_not_filtering = true. The latter mechanism has
been known for many years to be broken by design:
https://lore.kernel.org/netdev/CABumfLzJmXDN_W-8Z=p9KyKUVi_HhS7o_poBkeKHS2BkAiyYpw@mail.gmail.com/
and we have the situation of 2 bugs canceling each other. There is no
private VLAN, and the port follows the PVID of the VLAN-unaware bridge.
So, it's kinda ok for that driver to use the ds->untag_bridge_pvid
mechanism, in a broken way.

As explained by Horatiu Vultur in commit 603ead96582d ("net: sparx5: Add
spinlock for frame transmission from CPU") which is for a similar
hardware design, multiple CPUs can simultaneously perform injection
or extraction. There are only 2 register groups for injection and 2
for extraction, and the driver only uses one of each. So we'd better
serialize access using spin locks, otherwise frame corruption is
possible.
Note that unlike in sparx5, FDMA in ocelot does not have this issue
because struct ocelot_fdma_tx_ring already contains an xmit_lock.
I guess this is mostly a problem for NXP LS1028A, as that is dual core.
I don't think VSC7514 is. So I'm blaming the commit where LS1028A (aka
the felix DSA driver) started using register-based packet injection and
extraction.

register injection
Problem description
-------------------
On an NXP LS1028A (felix DSA driver) with the following configuration:
- ocelot-8021q tagging protocol
- VLAN-aware bridge (with STP) spanning at least swp0 and swp1
- 8021q VLAN upper interfaces on swp0 and swp1: swp0.700, swp1.700
- ptp4l on swp0.700 and swp1.700
we see that the ptp4l instances do not see each other's traffic,
and they all go to the grand master state due to the
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES condition.
Jumping to the conclusion for the impatient
-------------------------------------------
There is a zero-day bug in the ocelot switchdev driver in the way it
handles VLAN-tagged packet injection. The correct logic already exists in
the source code, in function ocelot_xmit_get_vlan_info() added by commit
5ca721c54d86 ("net: dsa: tag_ocelot: set the classified VLAN during xmit").
But it is used only for normal NPI-based injection with the DSA "ocelot"
tagging protocol. The other injection code paths (register-based and
FDMA-based) roll their own wrong logic. This affects and was noticed on
the DSA "ocelot-8021q" protocol because it uses register-based injection.
By moving ocelot_xmit_get_vlan_info() to a place that's common for both
the DSA tagger and the ocelot switch library, it can also be called from
ocelot_port_inject_frame() in ocelot.c.
We need to touch the lines with ocelot_ifh_port_set()'s prototype
anyway, so let's rename it to something clearer regarding what it does,
and add a kernel-doc. ocelot_ifh_set_basic() should do.
Investigation notes
-------------------
Debugging reveals that PTP event (aka those carrying timestamps, like
Sync) frames injected into swp0.700 (but also swp1.700) hit the wire
with two VLAN tags:
00000000: 01 1b 19 00 00 00 00 01 02 03 04 05 81 00 02 bc
~~~~~~~~~~~
00000010: 81 00 02 bc 88 f7 00 12 00 2c 00 00 02 00 00 00
~~~~~~~~~~~
00000020: 00 00 00 00 00 00 00 00 00 00 00 01 02 ff fe 03
00000030: 04 05 00 01 00 04 00 00 00 00 00 00 00 00 00 00
00000040: 00 00
The second (unexpected) VLAN tag makes felix_check_xtr_pkt() ->
ptp_classify_raw() fail to see these as PTP packets at the link
partner's receiving end, and return PTP_CLASS_NONE (because the BPF
classifier is not written to expect 2 VLAN tags).
The reason why packets have 2 VLAN tags is because the transmission
code treats VLAN incorrectly.
Neither ocelot switchdev, nor felix DSA, declare the NETIF_F_HW_VLAN_CTAG_TX
feature. Therefore, at xmit time, all VLANs should be in the skb head,
and none should be in the hwaccel area. This is done by:
static struct sk_buff *validate_xmit_vlan(struct sk_buff *skb,
netdev_features_t features)
{
if (skb_vlan_tag_present(skb) &&
!vlan_hw_offload_capable(features, skb->vlan_proto))
skb = __vlan_hwaccel_push_inside(skb);
return skb;
}
But ocelot_port_inject_frame() handles things incorrectly:
ocelot_ifh_port_set(ifh, port, rew_op, skb_vlan_tag_get(skb));
void ocelot_ifh_port_set(struct sk_buff *skb, void *ifh, int port, u32 rew_op)
{
(...)
if (vlan_tag)
ocelot_ifh_set_vlan_tci(ifh, vlan_tag);
(...)
}
The way __vlan_hwaccel_push_inside() pushes the tag inside the skb head
is by calling:
static inline void __vlan_hwaccel_clear_tag(struct sk_buff *skb)
{
skb->vlan_present = 0;
}
which does _not_ zero out skb->vlan_tci as seen by skb_vlan_tag_get().
This means that ocelot, when it calls skb_vlan_tag_get(), sees
(and uses) a residual skb->vlan_tci, while the same VLAN tag is
_already_ in the skb head.
The trivial fix for double VLAN headers is to replace the content of
ocelot_ifh_port_set() with:
if (skb_vlan_tag_present(skb))
ocelot_ifh_set_vlan_tci(ifh, skb_vlan_tag_get(skb));
but this would not be correct either, because, as mentioned,
vlan_hw_offload_capable() is false for us, so we'd be inserting dead
code and we'd always transmit packets with VID=0 in the injection frame
header.
I can't actually test the ocelot switchdev driver and rely exclusively
on code inspection, but I don't think traffic from 8021q uppers has ever
been injected properly, and not double-tagged. Thus I'm blaming the
introduction of VLAN fields in the injection header - early driver code.
As hinted at in the early conclusion, what we _want_ to happen for
VLAN transmission was already described once in commit 5ca721c54d86
("net: dsa: tag_ocelot: set the classified VLAN during xmit").
ocelot_xmit_get_vlan_info() intends to ensure that if the port through
which we're transmitting is under a VLAN-aware bridge, the outer VLAN
tag from the skb head is stripped from there and inserted into the
injection frame header (so that the packet is processed in hardware
through that actual VLAN). And in all other cases, the packet is sent
with VID=0 in the injection frame header, since the port is VLAN-unaware
and has logic to strip this VID on egress (making it invisible to the
wire).

In several cases we are freeing pages which were not allocated using
common page allocators. For such cases, in order to keep allocation
accounting correct, we should clear the page tag to indicate that the page
being freed is expected to not have a valid allocation tag. Introduce
clear_page_tag_ref() helper function to be used for this.
