change left a stray colon for the fan speed control method. Fix this
to avoid a confusion of readers.

Revert "venus: firmware: Correct non-pix start and end addresses"

This reverts commit a837e5161cff, which broke probing of the venus
driver, at least on the SC7180 SoC HP X2 Chromebook:

  qcom-venus aa00000.video-codec: Adding to iommu group 11
  qcom-venus aa00000.video-codec: non legacy binding
  qcom-venus aa00000.video-codec: failed to reset venus core
  qcom-venus: probe of aa00000.video-codec failed with error -110

Matthias Kaehlcke also reported that the same change caused a regression
in SC7180 and sc7280, that prevents AOSS from entering sleep mode during
system suspend.  So let's revert this commit for now to fix both issues.

media: i2c: imx290: fix conditional function defintions

The runtime suspend/resume functions are only referenced from the
dev_pm_ops, but they use the old SET_RUNTIME_PM_OPS() helper that
requires a __maybe_unused annotation to avoid a warning:

  drivers/media/i2c/imx290.c:1082:12: error: unused function 'imx290_runtime_resume' [-Werror,-Wunused-function]

Convert this to the new RUNTIME_PM_OPS() helper that so this is not
required.  To improve this further, also use the pm_ptr() helper that
lets the dev_pm_ops get dropped entirely when CONFIG_PM is disabled.

A related mistake happened in the of_match_ptr() macro here, which like
SET_RUNTIME_PM_OPS() requires the match table to be marked as
__maybe_unused, though I could not reproduce building this without
CONFIG_OF.  Remove the of_match_ptr() here as there is no point in
dropping the match table in configurations without CONFIG_OF.

Hans de Goede [Thu, 30 Mar 2023 19:46:44 +0000 (21:46 +0200)]
platform/x86: ideapad-laptop: Stop sending KEY_TOUCHPAD_TOGGLE

Commit 5829f8a897e4 ("platform/x86: ideapad-laptop: Send
KEY_TOUCHPAD_TOGGLE on some models") made ideapad-laptop send
KEY_TOUCHPAD_TOGGLE when we receive an ACPI notify with VPC event bit 5 set
and the touchpad-state has not been changed by the EC itself already.

This was done under the assumption that this would be good to do to make
the touchpad-toggle hotkey work on newer models where the EC does not
toggle the touchpad on/off itself (because it is not routed through
the PS/2 controller, but uses I2C).

But it turns out that at least some models, e.g. the Yoga 7-15ITL5 the EC
triggers an ACPI notify with VPC event bit 5 set on resume, which would
now cause a spurious KEY_TOUCHPAD_TOGGLE on resume to which the desktop
environment responds by disabling the touchpad in software, breaking
the touchpad (until manually re-enabled) on resume.

It was never confirmed that sending KEY_TOUCHPAD_TOGGLE actually improves
things on new models and at least some new models like the Yoga 7-15ITL5
don't have a touchpad on/off toggle hotkey at all, while still sending
ACPI notify events with VPC event bit 5 set.

So it seems best to revert the change to send KEY_TOUCHPAD_TOGGLE when
receiving an ACPI notify events with VPC event bit 5 and the touchpad
state as reported by the EC has not changed.

Note this is not a full revert the code to cache the last EC touchpad
state is kept to avoid sending spurious KEY_TOUCHPAD_ON / _OFF events
on resume.

The synchronize_rcu() will be invoked in the perf_pmu_migrate_context(),
when migrating a PMU to a new CPU. However, the current for_each_iommu()
is within RCU read-side critical section.

Two methods were considered to fix the issue.
- Use the dmar_global_lock to replace the RCU read lock when going
  through the drhd list. But it triggers a lockdep warning.
- Use the cpuhp_setup_state_multi() to set up a dedicated state for each
  IOMMU PMU. The lock can be avoided.

The latter method is implemented in this patch. Since each IOMMU PMU has
a dedicated state, add cpuhp_node and cpu in struct iommu_pmu to track
the state. The state can be dynamically allocated now. Remove the
CPUHP_AP_PERF_X86_IOMMU_PERF_ONLINE.

19 months agodm: fix __send_duplicate_bios() to always allow for splitting IO

dm: fix __send_duplicate_bios() to always allow for splitting IO

Commit 7dd76d1feec70 ("dm: improve bio splitting and associated IO
accounting") only called setup_split_accounting() from
__send_duplicate_bios() if a single bio were being issued. But the case
where duplicate bios are issued must call it too.

Otherwise the bio won't be split and resubmitted (via recursion through
block core back to DM) to submit the later portions of a bio (which may
map to an entirely different target).

For example, when discarding an entire DM striped device with the
following DM table:
 vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048

Before (broken, discards the first striped target's devices twice):
 device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872

 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528

After (works as expected):
 device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872

dm: fix improper splitting for abnormal bios

"Abnormal" bios include discards, write zeroes and secure erase. By no
longer passing the calculated 'len' pointer, commit 7dd06a2548b2 ("dm:
allow dm_accept_partial_bio() for dm_io without duplicate bios") took a
senseless approach to disallowing dm_accept_partial_bio() from working
for duplicate bios processed using __send_duplicate_bios().

It inadvertently and incorrectly stopped the use of 'len' when
initializing a target's io (in alloc_tio). As such the resulting tio
could address more area of a device than it should.

For example, when discarding an entire DM striped device with the
following DM table:
 vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048

Reported on the Turris forum, mvneta provokes kernel warnings in the
architecture DMA mapping code when mvneta_setup_txqs() fails to
allocate memory. This happens because when mvneta_cleanup_txqs() is
called in the mvneta_stop() path, we leave pointers in the structure
that have been freed.

Then on mvneta_open(), we call mvneta_setup_txqs(), which starts
allocating memory. On memory allocation failure, mvneta_cleanup_txqs()
will walk all the queues freeing any non-NULL pointers - which includes
pointers that were previously freed in mvneta_stop().

Fix this by setting these pointers to NULL to prevent double-freeing
of the same memory.

19 months agonet: dsa: sync unicast and multicast addresses for VLAN filters too
Vladimir Oltean [Wed, 29 Mar 2023 15:18:21 +0000 (18:18 +0300)]
net: dsa: sync unicast and multicast addresses for VLAN filters too

If certain conditions are met, DSA can install all necessary MAC
addresses on the CPU ports as FDB entries and disable flooding towards
the CPU (we call this RX filtering).

There is one corner case where this does not work.

ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
ip link set swp0 master br0 && ip link set swp0 up
ip link add link swp0 name swp0.100 type vlan id 100
ip link set swp0.100 up && ip addr add 192.168.100.1/24 dev swp0.100

Traffic through swp0.100 is broken, because the bridge turns on VLAN
filtering in the swp0 port (causing RX packets to be classified to the
FDB database corresponding to the VID from their 802.1Q header), and
although the 8021q module does call dev_uc_add() towards the real
device, that API is VLAN-unaware, so it only contains the MAC address,
not the VID; and DSA's current implementation of ndo_set_rx_mode() is
only for VID 0 (corresponding to FDB entries which are installed in an
FDB database which is only hit when the port is VLAN-unaware).

It's interesting to understand why the bridge does not turn on
IFF_PROMISC for its swp0 bridge port, and it may appear at first glance
that this is a regression caused by the logic in commit 2796d0c648c9
("bridge: Automatically manage port promiscuous mode."). After all,
a bridge port needs to have IFF_PROMISC by its very nature - it needs to
receive and forward frames with a MAC DA different from the bridge
ports' MAC addresses.

While that may be true, when the bridge is VLAN-aware *and* it has a
single port, there is no real reason to enable promiscuity even if that
is an automatic port, with flooding and learning (there is nowhere for
packets to go except to the BR_FDB_LOCAL entries), and this is how the
corner case appears. Adding a second automatic interface to the bridge
would make swp0 promisc as well, and would mask the corner case.

Given the dev_uc_add() / ndo_set_rx_mode() API is what it is (it doesn't
pass a VLAN ID), the only way to address that problem is to install host
FDB entries for the cartesian product of RX filtering MAC addresses and
VLAN RX filters.

We increase cache->nr_cached when we free into the cache but don't
decrease when we take from it, so in some time we'll get an empty
