[PATCH 6.1 001/114] hv_netvsc: Allocate memory in netvsc_dma_map() with GFP_ATOMIC

[Greg Kroah-Hartman]

From: Michael Kelley <mikelley@microsoft.com>

commit c6aa9d3b43cd11ac13a8220368a3b0483c6751d4 upstream.

Memory allocations in the network transmit path must use GFP_ATOMIC
so they won't sleep.

[PATCH 6.1 002/114] btrfs: limit device extents to the device size

[Greg Kroah-Hartman]

From: Josef Bacik <josef@toxicpanda.com>

commit 3c538de0f2a74d50aff7278c092f88ae59cee688 upstream.

There was a recent regression in btrfs/177 that started happening with
the size class patches ("btrfs: introduce size class to block group
allocator").  This however isn't a regression introduced by those
patches, but rather the bug was uncovered by a change in behavior in
these patches.  The patches triggered more chunk allocations in the
^free-space-tree case, which uncovered a race with device shrink.

The problem is we will set the device total size to the new size, and
use this to find a hole for a device extent.  However during shrink we
may have device extents allocated past this range, so we could
potentially find a hole in a range past our new shrink size.  We don't
actually limit our found extent to the device size anywhere, we assume
that we will not find a hole past our device size.  This isn't true with
shrink as we're relocating block groups and thus creating holes past the
device size.

Fix this by making sure we do not search past the new device size, and
if we wander into any device extents that start after our device size
simply break from the loop and use whatever hole we've already found.

[PATCH 6.1 003/114] btrfs: zlib: zero-initialize zlib workspace

[Greg Kroah-Hartman]

From: Alexander Potapenko <glider@google.com>

commit eadd7deca0ad8a83edb2b894d8326c78e78635d6 upstream.

KMSAN reports uses of uninitialized memory in zlib's longest_match()
called on memory originating from zlib_alloc_workspace().
This issue is known by zlib maintainers and is claimed to be harmless,
but to be on the safe side we'd better initialize the memory.

[PATCH 6.1 007/114] ALSA: hda/realtek: Enable mute/micmute LEDs on HP Elitebook, 645 G9

[Greg Kroah-Hartman]

From: Elvis Angelaccio <elvis.angelaccio@kde.org>

commit 9a6804aa1c92cd28e89e746ace44d5ba101db76c upstream.

The HP Elitebook 645 G9 laptop (with motherboard model 89D2) uses the
ALC236 codec and requires the alc236_fixup_hp_mute_led_micmute_vref
fixup in order to enable mute/micmute LEDs.

Note: the alc236_fixup_hp_gpio_led fixup, which is used by the Elitebook
640 G9, does not work with the 645 G9.

[PATCH 6.1 010/114] Revert "PCI/ASPM: Save L1 PM Substates Capability for suspend/resume"

[Greg Kroah-Hartman]

From: Bjorn Helgaas <bhelgaas@google.com>

commit a7152be79b627428c628da2a887ca4b2512a78fd upstream.

This reverts commit 4ff116d0d5fd8a025604b0802d93a2d5f4e465d1.

Tasev Nikola and Mark Enriquez reported that resume from suspend was broken
in v6.1-rc1.  Tasev bisected to a47126ec29f5 ("PCI/PTM: Cache PTM
Capability offset"), but we can't figure out how that could be related.

Mark saw the same symptoms and bisected to 4ff116d0d5fd ("PCI/ASPM: Save L1
PM Substates Capability for suspend/resume"), which does have a connection:
it restores L1 Substates configuration while ASPM L1 may be enabled:

  pci_restore_state
    pci_restore_aspm_l1ss_state
      aspm_program_l1ss
        pci_write_config_dword(PCI_L1SS_CTL1, ctl1)         # L1SS restore
    pci_restore_pcie_state
      pcie_capability_write_word(PCI_EXP_LNKCTL, cap[i++])  # L1 restore

which is a problem because PCIe r6.0, sec 5.5.4, requires that:

  If setting either or both of the enable bits for ASPM L1 PM
  Substates, both ports must be configured as described in this
  section while ASPM L1 is disabled.

Separately, Thomas Witt reported that 5e85eba6f50d ("PCI/ASPM: Refactor L1
PM Substates Control Register programming") broke suspend/resume, and it
depends on 4ff116d0d5fd.

Revert 4ff116d0d5fd ("PCI/ASPM: Save L1 PM Substates Capability for
suspend/resume") to fix the resume issue and enable revert of 5e85eba6f50d
to fix the issue Thomas reported.

Note that reverting 4ff116d0d5fd means L1 Substates config may be lost on
suspend/resume.  As far as we know the system will use more power but will
still *work* correctly.

[PATCH 6.1 011/114] Revert "PCI/ASPM: Refactor L1 PM Substates Control Register programming"

[Greg Kroah-Hartman]

From: Bjorn Helgaas <bhelgaas@google.com>

commit ff209ecc376a2ea8dd106a1f594427a5d94b7dd3 upstream.

This reverts commit 5e85eba6f50dc288c22083a7e213152bcc4b8208.

Thomas Witt reported that 5e85eba6f50d ("PCI/ASPM: Refactor L1 PM Substates
Control Register programming") broke suspend/resume on a Tuxedo
Infinitybook S 14 v5, which seems to use a Clevo L140CU Mainboard.

The main symptom is:

  iwlwifi 0000:02:00.0: Unable to change power state from D3hot to D0, device inaccessible
  nvme 0000:03:00.0: Unable to change power state from D3hot to D0, device inaccessible

and the machine is only partially usable after resume.  It can't run dmesg
and can't do a clean reboot.  This happens on every suspend/resume cycle.

Revert 5e85eba6f50d until we can figure out the root cause.

[PATCH 6.1 012/114] tracing: Fix poll() and select() do not work on per_cpu trace_pipe and trace_pipe_raw

[Greg Kroah-Hartman]

From: Shiju Jose <shiju.jose@huawei.com>

commit 3e46d910d8acf94e5360126593b68bf4fee4c4a1 upstream.

poll() and select() on per_cpu trace_pipe and trace_pipe_raw do not work
since kernel 6.1-rc6. This issue is seen after the commit
42fb0a1e84ff525ebe560e2baf9451ab69127e2b ("tracing/ring-buffer: Have
polling block on watermark").

This issue is firstly detected and reported, when testing the CXL error
events in the rasdaemon and also erified using the test application for poll()
and select().

This issue occurs for the per_cpu case, when calling the ring_buffer_poll_wait(),
in kernel/trace/ring_buffer.c, with the buffer_percent > 0 and then wait until the
percentage of pages are available. The default value set for the buffer_percent is 50
in the kernel/trace/trace.c.

As a fix, allow userspace application could set buffer_percent as 0 through
the buffer_percent_fops, so that the task will wake up as soon as data is added
to any of the specific cpu buffer.

[PATCH 6.1 013/114] of/address: Return an error when no valid dma-ranges are found

[Greg Kroah-Hartman]

From: Mark Brown <broonie@kernel.org>

commit f6933c01e42d2fc83b9133ed755609e4aac6eadd upstream.

Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range")
converted the parsing of dma-range properties to use code shared with the
PCI range parser. The intent was to introduce no functional changes however
in the case where we fail to translate the first resource instead of
returning -EINVAL the new code we return 0. Restore the previous behaviour
by returning an error if we find no valid ranges, the original code only
handled the first range but subsequently support for parsing all supplied
ranges was added.

This avoids confusing code using the parsed ranges which doesn't expect to
successfully parse ranges but have only a list terminator returned, this
fixes breakage with so far as I can tell all DMA for on SoC devices on the
Socionext Synquacer platform which has a firmware supplied DT. A bisect
identified the original conversion as triggering the issues there.

[PATCH 6.1 014/114] can: j1939: do not wait 250 ms if the same addr was already claimed

[Greg Kroah-Hartman]

From: Devid Antonio Filoni <devid.filoni@egluetechnologies.com>

commit 4ae5e1e97c44f4654516c1d41591a462ed62fa7b upstream.

The ISO 11783-5 standard, in "4.5.2 - Address claim requirements", states:
  d) No CF shall begin, or resume, transmission on the network until 250
     ms after it has successfully claimed an address except when
     responding to a request for address-claimed.

But "Figure 6" and "Figure 7" in "4.5.4.2 - Address-claim
prioritization" show that the CF begins the transmission after 250 ms
from the first AC (address-claimed) message even if it sends another AC
message during that time window to resolve the address contention with
another CF.

As stated in "4.4.2.3 - Address-claimed message":
  In order to successfully claim an address, the CF sending an address
  claimed message shall not receive a contending claim from another CF
  for at least 250 ms.

As stated in "4.4.3.2 - NAME management (NM) message":
  1) A commanding CF can
     d) request that a CF with a specified NAME transmit the address-
        claimed message with its current NAME.
  2) A target CF shall
     d) send an address-claimed message in response to a request for a
        matching NAME

Taking the above arguments into account, the 250 ms wait is requested
only during network initialization.

Do not restart the timer on AC message if both the NAME and the address
match and so if the address has already been claimed (timer has expired)
or the AC message has been sent to resolve the contention with another
CF (timer is still running).

[PATCH 6.1 015/114] HID: logitech: Disable hi-res scrolling on USB

[Greg Kroah-Hartman]

From: Bastien Nocera <hadess@hadess.net>

commit 690eb7dec72ae52d1d710d14a451844b4d0f4f19 upstream.

On some Logitech mice, such as the G903, and possibly the G403, the HID
events are generated on a different interface to the HID++ one.

If we enable hi-res through the HID++ interface, the HID interface
wouldn't know anything about it, and handle the events as if they were
regular scroll events, making the mouse unusable.

Disable hi-res scrolling on those devices until we implement scroll
events through HID++.

[PATCH 6.1 018/114] xfrm/compat: prevent potential spectre v1 gadget in xfrm_xlate32_attr()

[Greg Kroah-Hartman]

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit b6ee896385380aa621102e8ea402ba12db1cabff ]

  int type = nla_type(nla);

  if (type > XFRMA_MAX) {
            return -EOPNOTSUPP;
  }

@type is then used as an array index and can be used
as a Spectre v1 gadget.

  if (nla_len(nla) < compat_policy[type].len) {

array_index_nospec() can be used to prevent leaking
content of kernel memory to malicious users.

[PATCH 6.1 019/114] IB/IPoIB: Fix legacy IPoIB due to wrong number of queues

[Greg Kroah-Hartman]

From: Dragos Tatulea <dtatulea@nvidia.com>

[ Upstream commit e632291a2dbce45a24cddeb5fe28fe71d724ba43 ]

The cited commit creates child PKEY interfaces over netlink will
multiple tx and rx queues, but some devices doesn't support more than 1
tx and 1 rx queues. This causes to a crash when traffic is sent over the
PKEY interface due to the parent having a single queue but the child
having multiple queues.

This patch fixes the number of queues to 1 for legacy IPoIB at the
earliest possible point in time.

[PATCH 6.1 021/114] RDMA/irdma: Fix potential NULL-ptr-dereference

[Greg Kroah-Hartman]

From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>

[ Upstream commit 5d9745cead1f121974322b94ceadfb4d1e67960e ]

in_dev_get() can return NULL which will cause a failure once idev is
dereferenced in in_dev_for_each_ifa_rtnl(). This patch adds a
check for NULL value in idev beforehand.

[PATCH 6.1 024/114] of: Make OF framebuffer device names unique

[Greg Kroah-Hartman]

From: Michal Suchanek <msuchanek@suse.de>

[ Upstream commit 241d2fb56a18473af5f2ff0d512992a996eb64dd ]

Since Linux 5.19 this error is observed:

sysfs: cannot create duplicate filename '/devices/platform/of-display'

This is because multiple devices with the same name 'of-display' are
created on the same bus. Update the code to create numbered device names
for the displays.

Also, fix a node refcounting issue when exiting the boot display loop.

[PATCH 6.1 025/114] net: phylink: move phy_device_free() to correctly release phy device

[Greg Kroah-Hartman]

From: Clément Léger <clement.leger@bootlin.com>

[ Upstream commit ce93fdb5f2ca5c9e2a9668411cc39091507f8dc9 ]

After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.

[PATCH 6.1 029/114] ionic: clean interrupt before enabling queue to avoid credit race

[Greg Kroah-Hartman]

From: Neel Patel <neel.patel@amd.com>

[ Upstream commit e8797a058466b60fc5a3291b92430c93ba90eaff ]

Clear the interrupt credits before enabling the queue rather
than after to be sure that the enabled queue starts at 0 and
that we don't wipe away possible credits after enabling the
queue.

[PATCH 6.1 030/114] ionic: refactor use of ionic_rx_fill()

[Greg Kroah-Hartman]

From: Neel Patel <neel@pensando.io>

[ Upstream commit e55f0f5befc26e2ba6bb8c1f945ea8e37ee0e334 ]

The same pre-work code is used before each call to
ionic_rx_fill(), so bring it in and make it a part of
the routine.

[PATCH 6.1 031/114] ionic: missed doorbell workaround

[Greg Kroah-Hartman]

From: Allen Hubbe <allen.hubbe@amd.com>

[ Upstream commit b69585bfceceeffda940906cabfdaee4b47bde92 ]

In one version of the HW there is a remote possibility that it
will miss the doorbell ring.  This adds a bit of protection to
be sure we don't stall a queue from a missed doorbell.

[PATCH 6.1 032/114] cpufreq: qcom-hw: Fix cpufreq_driver->get() for non-LMH systems

[Greg Kroah-Hartman]

From: Douglas Anderson <dianders@chromium.org>

[ Upstream commit 51be2fffd65d9f9cb427030ab0ee85d791b4437d ]

On a sc7180-based Chromebook, when I go to
/sys/devices/system/cpu/cpu0/cpufreq I can see:

  cpuinfo_cur_freq:2995200
  cpuinfo_max_freq:1804800
  scaling_available_frequencies:300000 576000 ... 1708800 1804800
  scaling_cur_freq:1804800
  scaling_max_freq:1804800

As you can see the `cpuinfo_cur_freq` is bogus. It turns out that this
bogus info started showing up as of commit c72cf0cb1d77 ("cpufreq:
qcom-hw: Fix the frequency returned by cpufreq_driver->get()"). That
commit seems to assume that everyone is on the LMH bandwagon, but
sc7180 isn't.

Let's go back to the old code in the case where LMH isn't used.

[PATCH 6.1 033/114] uapi: add missing ip/ipv6 header dependencies for linux/stddef.h

[Greg Kroah-Hartman]

From: Herton R. Krzesinski <herton@redhat.com>

[ Upstream commit 03702d4d29be4e2510ec80b248dbbde4e57030d9 ]

Since commit 58e0be1ef6118 ("net: use struct_group to copy ip/ipv6
header addresses"), ip and ipv6 headers started to use the __struct_group
definition, which is defined at include/uapi/linux/stddef.h. However,
linux/stddef.h isn't explicitly included in include/uapi/linux/{ip,ipv6}.h,
which breaks build of xskxceiver bpf selftest if you install the uapi
headers in the system:

$ make V=1 xskxceiver -C tools/testing/selftests/bpf
...
make: Entering directory '(...)/tools/testing/selftests/bpf'
gcc -g -O0 -rdynamic -Wall -Werror (...)
In file included from xskxceiver.c:79:
/usr/include/linux/ip.h:103:9: error: expected specifier-qualifier-list before ‘__struct_group’
  103 |         __struct_group(/* no tag */, addrs, /* no attrs */,
      |         ^~~~~~~~~~~~~~
...

Include the missing <linux/stddef.h> dependency in ip.h and do the
same for the ipv6.h header.

[PATCH 6.1 034/114] net: microchip: sparx5: fix PTP init/deinit not checking all ports

[Greg Kroah-Hartman]

From: Casper Andersson <casper.casan@gmail.com>

[ Upstream commit d7d94b2612f5dc25d61dc7bf58aafe7b31f40191 ]

Check all ports instead of just port_count ports. PTP init was only
checking ports 0 to port_count. If the hardware ports are not mapped
starting from 0 then they would be missed, e.g. if only ports 20-30 were
mapped it would attempt to init ports 0-10, resulting in NULL pointers
when attempting to timestamp. Now it will init all mapped ports.

[PATCH 6.1 035/114] HID: amd_sfh: if no sensors are enabled, clean up

[Greg Kroah-Hartman]

From: Mario Limonciello <mario.limonciello@amd.com>

[ Upstream commit 7bcfdab3f0c6672ca52be3cb65a0550d8b99554b ]

It was reported that commit b300667b33b2 ("HID: amd_sfh: Disable the
interrupt for all command") had caused increased resume time on HP Envy
x360.

Before this commit 3 sensors were reported, but they were not actually
functional.  After this commit the sensors are no longer reported, but
also the resume time increased.

To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.

[PATCH 6.1 036/114] drm/i915: Dont do the WM0->WM1 copy w/a if WM1 is already enabled

[Greg Kroah-Hartman]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

[ Upstream commit 90d5e8301ac24550be80d193aa5582cab56c29fc ]

Due to a workaround we have to make sure the WM1 watermarks block/lines
values are sensible even when WM1 is disabled. To that end we copy those
values from WM0.

However since we now keep each wm level enabled on a per-plane basis
it doesn't seem necessary to do that copy when we already have an
enabled WM1 on the current plane. That is, we might be in a situation
where another plane can only do WM0 (and thus needs the copy) but
the current plane's WM1 is still perfectly valid (ie. fits into the
current DDB allocation).

Skipping the copy could avoid reprogramming the plane's registers
needlessly in some cases.

[PATCH 6.1 037/114] drm/virtio: exbuf->fence_fd unmodified on interrupted wait

[ Upstream commit 8f20660f053cefd4693e69cfff9cf58f4f7c4929 ]

An interrupted dma_fence_wait() becomes an -ERESTARTSYS returned
to userspace ioctl(DRM_IOCTL_VIRTGPU_EXECBUFFER) calls, prompting to
retry the ioctl(), but the passed exbuf->fence_fd has been reset to -1,
making the retry attempt fail at sync_file_get_fence().

The uapi for DRM_IOCTL_VIRTGPU_EXECBUFFER is changed to retain the
passed value for exbuf->fence_fd when returning anything besides a
successful result from the ioctl.

[PATCH 6.1 038/114] cpuset: Call set_cpus_allowed_ptr() with appropriate mask for task

[Greg Kroah-Hartman]

From: Will Deacon <will@kernel.org>

[ Upstream commit 7a2127e66a00e073db8d90f9aac308f4a8a64226 ]

set_cpus_allowed_ptr() will fail with -EINVAL if the requested
affinity mask is not a subset of the task_cpu_possible_mask() for the
task being updated. Consequently, on a heterogeneous system with cpusets
spanning the different CPU types, updates to the cgroup hierarchy can
silently fail to update task affinities when the effective affinity
mask for the cpuset is expanded.

For example, consider an arm64 system with 4 CPUs, where CPUs 2-3 are
the only cores capable of executing 32-bit tasks. Attaching a 32-bit
task to a cpuset containing CPUs 0-2 will correctly affine the task to
CPU 2. Extending the cpuset to CPUs 0-3, however, will fail to extend
the affinity mask of the 32-bit task because update_tasks_cpumask() will
pass the full 0-3 mask to set_cpus_allowed_ptr().

Extend update_tasks_cpumask() to take a temporary 'cpumask' paramater
and use it to mask the 'effective_cpus' mask with the possible mask for
each task being updated.

[PATCH 6.1 039/114] nvidiafb: detect the hardware support before removing console.

[Greg Kroah-Hartman]

From: Dave Airlie <airlied@redhat.com>

[ Upstream commit 04119ab1a49fc41cb70f0472be5455af268fa260 ]

This driver removed the console, but hasn't yet decided if it could
take over the console yet. Instead of doing that, probe the hw for
support and then remove the console afterwards.

[PATCH 6.1 040/114] ice: Do not use WQ_MEM_RECLAIM flag for workqueue

[Greg Kroah-Hartman]

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

[ Upstream commit 4d159f7884f78b1aacb99b4fc37d1e3cb1194e39 ]

When both ice and the irdma driver are loaded, a warning in
check_flush_dependency is being triggered. This is due to ice driver
workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.

According to kernel documentation, this flag should be set if the
workqueue will be involved in the kernel's memory reclamation flow.
Since it is not, there is no need for the ice driver's WQ to have this
flag set so remove it.

Example trace:

[PATCH 6.1 041/114] ice: Fix disabling Rx VLAN filtering with port VLAN enabled

[Greg Kroah-Hartman]

From: Brett Creeley <brett.creeley@intel.com>

[ Upstream commit c793f8ea15e312789b5b6b4a5e7b0b92315be5cb ]

If the user turns on the vf-true-promiscuous-support flag, then Rx VLAN
filtering will be disabled if the VF requests to enable promiscuous
mode. When the VF is in a port VLAN, this is the incorrect behavior
because it will allow the VF to receive traffic outside of its port VLAN
domain. Fortunately this only resulted in the VF(s) receiving broadcast
traffic outside of the VLAN domain because all of the VLAN promiscuous
rules are based on the port VLAN ID. Fix this by setting the
.disable_rx_filtering VLAN op to a no-op when a port VLAN is enabled on
the VF.

Also, make sure to make this fix for both Single VLAN Mode and Double
VLAN Mode enabled devices.

[PATCH 6.1 042/114] ice: switch: fix potential memleak in ice_add_adv_recipe()

[Greg Kroah-Hartman]

From: Zhang Changzhong <zhangchangzhong@huawei.com>

[ Upstream commit 4a606ce68426c88ff2563382b33cc34f3485fe57 ]

When ice_add_special_words() fails, the 'rm' is not released, which will
lead to a memory leak. Fix this up by going to 'err_unroll' label.

Compile tested only.

[PATCH 6.1 043/114] net: dsa: mt7530: dont change PVC_EG_TAG when CPU port becomes VLAN-aware

[Greg Kroah-Hartman]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

[ Upstream commit 0b6d6425103a676e2b6a81f3fd35d7ea4f9b90ec ]

Frank reports that in a mt7530 setup where some ports are standalone and
some are in a VLAN-aware bridge, 8021q uppers of the standalone ports
lose their VLAN tag on xmit, as seen by the link partner.

This seems to occur because once the other ports join the VLAN-aware
bridge, mt7530_port_vlan_filtering() also calls
mt7530_port_set_vlan_aware(ds, cpu_dp->index), and this affects the way
that the switch processes the traffic of the standalone port.

Relevant is the PVC_EG_TAG bit. The MT7530 documentation says about it:

EG_TAG: Incoming Port Egress Tag VLAN Attribution
0: disabled (system default)
1: consistent (keep the original ingress tag attribute)

My interpretation is that this setting applies on the ingress port, and
"disabled" is basically the normal behavior, where the egress tag format
of the packet (tagged or untagged) is decided by the VLAN table
(MT7530_VLAN_EGRESS_UNTAG or MT7530_VLAN_EGRESS_TAG).

But there is also an option of overriding the system default behavior,
and for the egress tagging format of packets to be decided not by the
VLAN table, but simply by copying the ingress tag format (if ingress was
tagged, egress is tagged; if ingress was untagged, egress is untagged;
aka "consistent). This is useful in 2 scenarios:

- VLAN-unaware bridge ports will always encounter a miss in the VLAN
  table. They should forward a packet as-is, though. So we use
  "consistent" there. See commit e045124e9399 ("net: dsa: mt7530: fix
  tagged frames pass-through in VLAN-unaware mode").

- Traffic injected from the CPU port. The operating system is in god
  mode; if it wants a packet to exit as VLAN-tagged, it sends it as
  VLAN-tagged. Otherwise it sends it as VLAN-untagged*.

*This is true only if we don't consider the bridge TX forwarding offload
feature, which mt7530 doesn't support.

So for now, make the CPU port always stay in "consistent" mode to allow
software VLANs to be forwarded to their egress ports with the VLAN tag
intact, and not stripped.

[PATCH 6.1 044/114] net: mscc: ocelot: fix VCAP filters not matching on MAC with "protocol 802.1Q"

[Greg Kroah-Hartman]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

[ Upstream commit f964f8399df29d3e3ced77177cf35131cd2491bf ]

Alternative short title: don't instruct the hardware to match on
EtherType with "protocol 802.1Q" flower filters. It doesn't work for the
reasons detailed below.

With a command such as the following:

tc filter add dev $swp1 ingress chain $(IS1 2) pref 3 \
	protocol 802.1Q flower skip_sw vlan_id 200 src_mac $h1_mac \
	action vlan modify id 300 \
	action goto chain $(IS2 0 0)

the created filter is set by ocelot_flower_parse_key() to be of type
OCELOT_VCAP_KEY_ETYPE, and etype is set to {value=0x8100, mask=0xffff}.
This gets propagated all the way to is1_entry_set() which commits it to
hardware (the VCAP_IS1_HK_ETYPE field of the key). Compare this to the
case where src_mac isn't specified - the key type is OCELOT_VCAP_KEY_ANY,
and is1_entry_set() doesn't populate VCAP_IS1_HK_ETYPE.

The problem is that for VLAN-tagged frames, the hardware interprets the
ETYPE field as holding the encapsulated VLAN protocol. So the above
filter will only match those packets which have an encapsulated protocol
of 0x8100, rather than all packets with VLAN ID 200 and the given src_mac.

The reason why this is allowed to occur is because, although we have a
block of code in ocelot_flower_parse_key() which sets "match_protocol"
to false when VLAN keys are present, that code executes too late.
There is another block of code, which executes for Ethernet addresses,
and has a "goto finished_key_parsing" and skips the VLAN header parsing.
By skipping it, "match_protocol" remains with the value it was
initialized with, i.e. "true", and "proto" is set to f->common.protocol,
or 0x8100.

The concept of ignoring some keys rather than erroring out when they are
present but can't be offloaded is dubious in itself, but is present
since the initial commit fe3490e6107e ("net: mscc: ocelot: Hardware
ofload for tc flower filter"), and it's outside of the scope of this
patch to change that.

The problem was introduced when the driver started to interpret the
flower filter's protocol, and populate the VCAP filter's ETYPE field
based on it.

To fix this, it is sufficient to move the code that parses the VLAN keys
earlier than the "goto finished_key_parsing" instruction. This will
ensure that if we have a flower filter with both VLAN and Ethernet
address keys, it won't match on ETYPE 0x8100, because the VLAN key
parsing sets "match_protocol = false".

[PATCH 6.1 045/114] net/mlx5e: Update rx ring hw mtu upon each rx-fcs flag change

[Greg Kroah-Hartman]

From: Adham Faris <afaris@nvidia.com>

[ Upstream commit 1e66220948df815d7b37e0ff8b4627ce10433738 ]

rq->hw_mtu is used in function en_rx.c/mlx5e_skb_from_cqe_mpwrq_linear()
to catch oversized packets. If FCS is concatenated to the end of the
packet then the check should be updated accordingly.

Rx rings initialization (mlx5e_init_rxq_rq()) invoked for every new set
of channels, as part of mlx5e_safe_switch_params(), unknowingly if it
runs with default configuration or not. Current rq->hw_mtu
initialization assumes default configuration and ignores
params->scatter_fcs_en flag state.
Fix this, by accounting for params->scatter_fcs_en flag state during
rq->hw_mtu initialization.

In addition, updating rq->hw_mtu value during ingress traffic might
lead to packets drop and oversize_pkts_sw_drop counter increase with no
good reason. Hence we remove this optimization and switch the set of
channels with a new one, to make sure we don't get false positives on
the oversize_pkts_sw_drop counter.

[PATCH 6.1 047/114] net/mlx5e: Fix crash unsetting rx-vlan-filter in switchdev mode

From: Amir Tzin <amirtz@nvidia.com>

[ Upstream commit 8974aa9638df557f4642acef707af15648a03555 ]

Moving to switchdev mode with rx-vlan-filter on and then setting it off
causes the kernel to crash since fs->vlan is freed during nic profile
cleanup flow.

RX VLAN filtering is not supported in switchdev mode so unset it when
changing to switchdev and restore its value when switching back to

[PATCH 6.1 048/114] net/mlx5e: IPoIB, Show unknown speed instead of error

[Greg Kroah-Hartman]

From: Dragos Tatulea <dtatulea@nvidia.com>

[ Upstream commit 8aa5f171d51c1cb69e5e3106df4dd1a446102823 ]

ethtool is returning an error for unknown speeds for the IPoIB interface:

$ ethtool ib0
netlink error: failed to retrieve link settings
netlink error: Invalid argument
netlink error: failed to retrieve link settings
netlink error: Invalid argument
Settings for ib0:

After this change, ethtool will return success and show "unknown speed":

$ ethtool ib0
Settings for ib0:

Supported link modes:   Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported

[PATCH 6.1 049/114] net/mlx5: Store page counters in a single array

[Greg Kroah-Hartman]

From: Maher Sanalla <msanalla@nvidia.com>

[ Upstream commit c3bdbaea654d8df39112de33037106134a520dc7 ]

Currently, an independent page counter is used for tracking memory usage
for each function type such as VF, PF and host PF (DPU).

For better code-readibilty, use a single array that stores
the number of allocated memory pages for each function type.

[PATCH 6.1 050/114] net/mlx5: Expose SF firmware pages counter

[Greg Kroah-Hartman]

From: Maher Sanalla <msanalla@nvidia.com>

[ Upstream commit 9965bbebae59b3563a4d95e4aed121e8965dfdc2 ]

Currently, each core device has VF pages counter which stores number of
fw pages used by its VFs and SFs.

The current design led to a hang when performing firmware reset on DPU,
where the DPU PFs stalled in sriov unload flow due to waiting on release
of SFs pages instead of waiting on only VFs pages.

Thus, Add a separate counter for SF firmware pages, which will prevent
the stall scenario described above.

[PATCH 6.1 051/114] net/mlx5: fw_tracer, Clear load bit when freeing string DBs buffers

[Greg Kroah-Hartman]

From: Shay Drory <shayd@nvidia.com>

[ Upstream commit db561fed6b8fa3878e74d5df6512a4a38152b63e ]

Whenever the driver is reading the string DBs into buffers, the driver
is setting the load bit, but the driver never clears this bit.
As a result, in case load bit is on and the driver query the device for
new string DBs, the driver won't read again the string DBs.
Fix it by clearing the load bit when query the device for new string
DBs.

[PATCH 6.1 052/114] net/mlx5: fw_tracer, Zero consumer index when reloading the tracer

[Greg Kroah-Hartman]

From: Shay Drory <shayd@nvidia.com>

[ Upstream commit 184e1e4474dbcfebc4dbd1fa823a329978f25506 ]

When tracer is reloaded, the device will log the traces at the
beginning of the log buffer. Also, driver is reading the log buffer in
chunks in accordance to the consumer index.
Hence, zero consumer index when reloading the tracer.

[PATCH 6.1 053/114] net/mlx5: Serialize module cleanup with reload and remove

[Greg Kroah-Hartman]

From: Shay Drory <shayd@nvidia.com>

[ Upstream commit 8f0d1451ecf7b3bd5a06ffc866c753d0f3ab4683 ]

Currently, remove and reload flows can run in parallel to module cleanup.
This design is error prone. For example: aux_drivers callbacks are called
from both cleanup and remove flows with different lockings, which can
cause a deadlock[1].
Hence, serialize module cleanup with reload and remove.

[PATCH 6.1 054/114] igc: Add ndo_tx_timeout support

[Greg Kroah-Hartman]

From: Sasha Neftin <sasha.neftin@intel.com>

[ Upstream commit 9b275176270efd18f2f4e328b32be1bad34c4c0d ]

On some platforms, 100/1000/2500 speeds seem to have sometimes problems
reporting false positive tx unit hang during stressful UDP traffic. Likely
other Intel drivers introduce responses to a tx hang. Update the 'tx hang'
comparator with the comparison of the head and tail of ring pointers and
restore the tx_timeout_factor to the previous value (one).

This can be test by using netperf or iperf3 applications.
Example:
iperf3 -s -p 5001
iperf3 -c 192.168.0.2 --udp -p 5001 --time 600 -b 0

netserver -p 16604
netperf -H 192.168.0.2 -l 600 -p 16604 -t UDP_STREAM -- -m 64000

[PATCH 6.1 056/114] txhash: fix sk->sk_txrehash default

[Greg Kroah-Hartman]

From: Kevin Yang <yyd@google.com>

[ Upstream commit c11204c78d6966c5bda6dd05c3ac5cbb193f93e3 ]

This code fix a bug that sk->sk_txrehash gets its default enable
value from sysctl_txrehash only when the socket is a TCP listener.

We should have sysctl_txrehash to set the default sk->sk_txrehash,
no matter TCP, nor listerner/connector.

Tested by following packetdrill:
  0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
  +0 socket(..., SOCK_DGRAM, IPPROTO_UDP) = 4
  // SO_TXREHASH == 74, default to sysctl_txrehash == 1
  +0 getsockopt(3, SOL_SOCKET, 74, [1], [4]) = 0
  +0 getsockopt(4, SOL_SOCKET, 74, [1], [4]) = 0

The PGID_MCIPV6 is configured correctly to not flood to the CPU,
I checked that.

Furthermore, when I disable back PTP RX timestamping (ptp4l doesn't do
that when it exists), packets are RX filtered again as they should be:

So it's clear that something in the PTP RX trapping logic went wrong.

Looking a bit at the code, I can see that there are 4 typos, which
populate "ipv4" VCAP IS2 key filter fields for IPv6 keys.

VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are
handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at
&filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6.
Simply put, when we populate the wrong key field, &filter->key.ipv6
fields "proto.mask" and "proto.value" remain all zeroes (or "don't care").
So is2_entry_set() will enter the "else" of this "if" condition:

	if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP))

and proceed to ignore the "proto" field. The resulting rule will match
on all IPv6 traffic, trapping it to the CPU.

This is the reason why the local_termination.sh selftest sees it,
because control traps are stronger than the PGID_MCIPV6 used for
flooding (from the forwarding data path).

But the problem is in fact much deeper. We trap all IPv6 traffic to the
CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software
forwarding will not take place and IPv6 traffic will never reach its
destination.

The fix is simple - correct the typos.

I was intentionally inaccurate in the commit message about the breakage
occurring when any PTP timestamping is enabled. In fact it only happens
when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or
HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX
timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT.
I wanted people skimming through git logs to not think that the bug
doesn't affect them because they only use ptp4l in L2 mode.

[PATCH 6.1 061/114] arm64: dts: rockchip: fix input enable pinconf on rk3399

[Greg Kroah-Hartman]

From: Arnaud Ferraris <arnaud.ferraris@collabora.com>

[ Upstream commit 6f515b663d49a14fb63f8c5d0a2a4ae53d44790a ]

When the input enable pinconf was introduced, a default drive-strength
value of 2 was set for the pull up/down configs. However, this parameter
is unneeded when configuring the pin as input, and having a single
hardcoded value here is actually harmful: GPIOs on the RK3399 have
various same drive-strength capabilities depending on the bank and port
they belong to.

As an example, trying to configure the GPIO4_PD3 pin as an input with
pull-up enabled fails with the following output:

  [   10.706542] rockchip-pinctrl pinctrl: unsupported driver strength 2
  [   10.713661] rockchip-pinctrl pinctrl: pin_config_set op failed for pin 155

(acceptable drive-strength values for this pin being 3, 6, 9 and 12)

Let's drop the drive-strength property from all input pinconfs in order
to solve this issue.

From: Dan Carpenter <error27@gmail.com>

[ Upstream commit 5dac9f8dc25fefd9d928b98f6477ff3daefd73e3 ]

This loop accidentally reuses the "i" iterator for both the inside and
the outside loop.  The value of MAX_STREAM_BUFFER is 5.  I believe that
chip->rmh.stat_len is in the 2-12 range.  If the value of .stat_len is
4 or more then it will loop exactly one time, but if it's less then it
is a forever loop.

It looks like it was supposed to combined into one loop where
conditions are checked.

[PATCH 6.1 064/114] riscv: stacktrace: Fix missing the first frame

From: Liu Shixin <liushixin2@huawei.com>

[ Upstream commit cb80242cc679d6397e77d8a964deeb3ff218d2b5 ]

When running kfence_test, I found some testcases failed like this:

 # test_out_of_bounds_read: EXPECTATION FAILED at mm/kfence/kfence_test.c:346
 Expected report_matches(&expect) to be true, but is false
 not ok 1 - test_out_of_bounds_read

The corresponding call-trace is:

 BUG: KFENCE: out-of-bounds read in kunit_try_run_case+0x38/0x84

 Out-of-bounds read at 0x(____ptrval____) (32B right of kfence-#10):

  kunit_generic_run_threadfn_adapter+0x12/0x1e
  kthread+0xc8/0xde

The kfence_test using the first frame of call trace to check whether the
testcase is succeed or not. Commit 6a00ef449370 ("riscv: eliminate
unreliable __builtin_frame_address(1)") skip first frame for all
case, which results the kfence_test failed. Indeed, we only need to skip
the first frame for case (task==NULL || task==current).

[PATCH 6.1 065/114] arm64: dts: mediatek: mt8195: Fix vdosys* compatible strings

[Greg Kroah-Hartman]

From: Chen-Yu Tsai <wenst@chromium.org>

[ Upstream commit 97801cfcf9565247bcc53b67ea47fa87b1704375 ]

When vdosys1 was initially added, it was incorrectly assumed to be
compatible with vdosys0, and thus both had the same mt8195-mmsys
compatible attached.

This has since been corrected in commit b237efd47df7 ("dt-bindings:
arm: mediatek: mmsys: change compatible for MT8195") and commit
82219cfbef18 ("dt-bindings: arm: mediatek: mmsys: add vdosys1 compatible
for MT8195"). The device tree needs to be fixed as well, otherwise
the vdosys1 block fails to work, and causes its dependent power domain
controller to not work either.

Change the compatible string of vdosys1 to "mediatek,mt8195-vdosys1".
While at it, also add the new "mediatek,mt8195-vdosys0" compatible to
vdosys0.

[PATCH 6.1 066/114] ASoC: tas5805m: rework to avoid scheduling while atomic.

[Greg Kroah-Hartman]

From: Daniel Beer <daniel.beer@igorinstitute.com>

[ Upstream commit 147323792693bf013f60dca160be1d32bd4d180a ]

There's some setup we need to do in order to get the DSP initialized,
and this can't be done until a bit-clock is ready. In an earlier version
of this driver, this work was done in a DAPM callback.

The DAPM callback doesn't guarantee that the bit-clock is running, so
the work was moved instead to the trigger callback. Unfortunately this
callback runs in atomic context, and the setup code needs to do I2C
transactions.

Here we use a work_struct to kick off the setup in a thread instead.

In tas5805m_refresh, we switch pages to update the DSP volume control,
but we need to switch back to page 0 before trying to alter the
soft-mute control. This latter page-switch was missing.

[PATCH 6.1 070/114] clk: microchip: mpfs-ccc: Use devm_kasprintf() for allocating formatted strings

[Greg Kroah-Hartman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ Upstream commit 86d884f5287f4369c198811aaa4931a3a11f36d2 ]

In various places, string buffers of a fixed size are allocated, and
filled using snprintf() with the same fixed size, which is error-prone.

Replace this by calling devm_kasprintf() instead, which always uses the
appropriate size.

While at it, remove an unneeded intermediate variable, which allows us
to drop a cast as a bonus.

With the initial behavior it would have been possible to have a device tree
with a node address that would make "ccc<node_address>_pll<N>" exceed
18 characters. If that happened, the <N> would be cut off & both
pll 0 & 1 would be named identically. If that happens, pll1 would fail
to register. Thus, the fixes tag has been added to this commit.

From: Guodong Liu <Guodong.Liu@mediatek.com>

[ Upstream commit 5754a1c98b18009cb3030dc391aa37b77428a0bd ]

The drive adjustment register definition of gpio13 and gpio81 is wrong:
"the start address for the range" of gpio18 is corrected to 0x000,
"the start bit for the first register within the range" of gpio81 is
corrected to 24.

[PATCH 6.1 074/114] spi: dw: Fix wrong FIFO level setting for long xfers

[Greg Kroah-Hartman]

From: Serge Semin <Sergey.Semin@baikalelectronics.ru>

[ Upstream commit c63b8fd14a7db719f8252038a790638728c4eb66 ]

Due to using the u16 type in the min_t() macros the SPI transfer length
will be cast to word before participating in the conditional statement
implied by the macro. Thus if the transfer length is greater than 64KB the
Tx/Rx FIFO threshold level value will be determined by the leftover of the
truncated after the type-case length. In the worst case it will cause the
dramatical performance drop due to the "Tx FIFO Empty" or "Rx FIFO Full"
interrupts triggered on each xfer word sent/received to/from the bus.

The problem can be easily fixed by specifying the unsigned int type in the
min_t() macros thus preventing the possible data loss.

[PATCH 6.1 075/114] pinctrl: aspeed: Revert "Force to disable the functions signal"

[Greg Kroah-Hartman]

From: Joel Stanley <joel@jms.id.au>

[ Upstream commit 606d4ef4922662ded34aa7218288c3043ce0a41a ]

This reverts commit cf517fef601b9dde151f0afc27164d13bf1fd907.

The commit cf517fef601b ("pinctrl: aspeed: Force to disable the
function's signal") exposed a problem with fetching the regmap for
reading the GFX register.

The Romulus machine the device tree contains a gpio hog for GPIO S7.
With the patch applied:

  Muxing pin 151 for GPIO
  Disabling signal VPOB9 for VPO
  aspeed-g5-pinctrl 1e6e2080.pinctrl: Failed to acquire regmap for IP block 1
  aspeed-g5-pinctrl 1e6e2080.pinctrl: request() failed for pin 151

The code path is aspeed-gpio -> pinmux-g5 -> regmap -> clk, and the
of_clock code returns an error as it doesn't have a valid struct clk_hw
pointer. The regmap call happens because pinmux wants to check the GFX
node (IP block 1) to query bits there.

For reference, before the offending patch:

  Muxing pin 151 for GPIO
  Disabling signal VPOB9 for VPO
  Want SCU8C[0x00000080]=0x1, got 0x0 from 0x00000000
  Disabling signal VPOB9 for VPOOFF1
  Want SCU8C[0x00000080]=0x1, got 0x0 from 0x00000000
  Disabling signal VPOB9 for VPOOFF2
  Want SCU8C[0x00000080]=0x1, got 0x0 from 0x00000000
  Enabling signal GPIOS7 for GPIOS7
  Muxed pin 151 as GPIOS7
  gpio-943 (seq_cont): hogged as output/low

We can't skip the clock check to allow pinmux to proceed, because the
write to disable VPOB9 will try to set a bit in the GFX register space
which will not stick when the IP is in reset. However, we do not want to
enable the IP just so pinmux can do a disable-enable dance for the pin.

For now, revert the offending patch while a correct solution is found.

Similarly, this problem also occurs in the uncache_fill_pages().

Fix this by adjusts the order of condition judgment in the return
statement.

[PATCH 6.1 079/114] mptcp: do not wait for bare sockets timeout

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

commit d4e85922e3e7ef2071f91f65e61629b60f3a9cf4 upstream.

If the peer closes all the existing subflows for a given
mptcp socket and later the application closes it, the current
implementation let it survive until the timewait timeout expires.

While the above is allowed by the protocol specification it
consumes resources for almost no reason and additionally
causes sporadic self-tests failures.

Let's move the mptcp socket to the TCP_CLOSE state when there are
no alive subflows at close time, so that the allocated resources
will be freed immediately.

[PATCH 6.1 080/114] mptcp: be careful on subflow status propagation on errors

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

commit 1249db44a102d9d3541ed7798d4b01ffdcf03524 upstream.

Currently the subflow error report callback unconditionally
propagates the fallback subflow status to the owning msk.

If the msk is already orphaned, the above prevents the code
from correctly tracking the msk moving to the TCP_CLOSE state
and doing the appropriate cleanup.

All the above causes increasing memory usage over time and
sporadic self-tests failures.

There is a great deal of infrastructure trying to propagate
correctly the fallback subflow status to the owning mptcp socket,
e.g. via mptcp_subflow_eof() and subflow_sched_work_if_closed():
in the error propagation path we need only to cope with unorphaned
sockets.

[PATCH 6.1 081/114] selftests: mptcp: allow more slack for slow test-case

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

commit a635a8c3df66ab68dc088c08a4e9e955e22c0e64 upstream.

A test-case is frequently failing on some extremely slow VMs.
The mptcp transfer completes before the script is able to do
all the required PM manipulation.

Address the issue in the simplest possible way, making the
transfer even more slow.

Additionally dump more info in case of failures, to help debugging
similar problems in the future and init dump_stats var.

[PATCH 6.1 082/114] selftests: mptcp: stop tests earlier

[Greg Kroah-Hartman]

From: Matthieu Baerts <matthieu.baerts@tessares.net>

commit 070d6dafacbaa9d1f2e4e3edc263853d194af15e upstream.

These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in
the background and check the status during this transfer.

Once the expected events have been recorded, there is no reason to wait
for the data transfer to finish. It can be stopped earlier to reduce the
execution time by more than half.

For these tests, the exchanged data were not verified. Errors, if any,
were ignored but that's fine, plenty of other tests are looking at that.
It is then OK to mute stderr now that we are sure errors will be printed
(and still ignored) because the transfer is stopped before the end.

[PATCH 6.1 083/114] btrfs: simplify update of last_dir_index_offset when logging a directory

[Greg Kroah-Hartman]

From: Filipe Manana <fdmanana@suse.com>

commit 6afaed53cc9adde69d8a76ff5b4d740d5efbc54c upstream.

When logging a directory, we always set the inode's last_dir_index_offset
to the offset of the last dir index item we found. This is using an extra
field in the log context structure, and it makes more sense to update it
only after we insert dir index items, and we could directly update the
inode's last_dir_index_offset field instead.

So make this simpler by updating the inode's last_dir_index_offset only
when we actually insert dir index keys in the log tree, and getting rid
of the last_dir_item_offset field in the log context structure.

[PATCH 6.1 084/114] btrfs: free device in btrfs_close_devices for a single device filesystem

[Greg Kroah-Hartman]

From: Anand Jain <anand.jain@oracle.com>

commit 5f58d783fd7823b2c2d5954d1126e702f94bfc4c upstream.

We have this check to make sure we don't accidentally add older devices
that may have disappeared and re-appeared with an older generation from
being added to an fs_devices (such as a replace source device). This
makes sense, we don't want stale disks in our file system. However for
single disks this doesn't really make sense.

I've seen this in testing, but I was provided a reproducer from a
project that builds btrfs images on loopback devices. The loopback
device gets cached with the new generation, and then if it is re-used to
generate a new file system we'll fail to mount it because the new fs is
"older" than what we have in cache.

Fix this by freeing the cache when closing the device for a single device
filesystem. This will ensure that the mount command passed device path is
scanned successfully during the next mount.

[PATCH 6.1 086/114] usb: typec: altmodes/displayport: Fix probe pin assign check

[Greg Kroah-Hartman]

From: Prashant Malani <pmalani@chromium.org>

commit 54e5c00a4eb0a4c663445b245f641bbfab142430 upstream.

While checking Pin Assignments of the port and partner during probe, we
don't take into account whether the peripheral is a plug or receptacle.

This manifests itself in a mode entry failure on certain docks and
dongles with captive cables. For instance, the Startech.com Type-C to DP
dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail
the Pin Assignment compatibility check, despite it supporting
Pin Assignment C as a UFP.

Update the check to use the correct DP Pin Assign macros that
take the peripheral's receptacle bit into account.

[PATCH 6.1 087/114] cxl/region: Fix null pointer dereference for resetting decoder

[Greg Kroah-Hartman]

From: Fan Ni <fan.ni@samsung.com>

commit 4fa4302d6dc7de7e8e74dc7405611a2efb4bf54b upstream.

Not all decoders have a reset callback.

The CXL specification allows a host bridge with a single root port to
have no explicit HDM decoders. Currently the region driver assumes there
are none.  As such the CXL core creates a special pass through decoder
instance without a commit/reset callback.

Prior to this patch, the ->reset() callback was called unconditionally when
calling cxl_region_decode_reset. Thus a configuration with 1 Host Bridge,
1 Root Port, and one directly attached CXL type 3 device or multiple CXL
type 3 devices attached to downstream ports of a switch can cause a null
pointer dereference.

Before the fix, a kernel crash was observed when we destroy the region, and
a pass through decoder is reset.

The issue can be reproduced as below,
    1) create a region with a CXL setup which includes a HB with a
    single root port under which a memdev is attached directly.
    2) destroy the region with cxl destroy-region regionX -f.

[PATCH 6.1 088/114] cxl/region: Fix passthrough-decoder detection

[Greg Kroah-Hartman]

From: Dan Williams <dan.j.williams@intel.com>

commit 711442e29f16f0d39dd0e2460c9baacfccb9d5a7 upstream.

A passthrough decoder is a decoder that maps only 1 target. It is a
special case because it does not impose any constraints on the
interleave-math as compared to a decoder with multiple targets. Extend
the passthrough case to multi-target-capable decoders that only have one
target selected. I.e. the current code was only considering passthrough
*ports* which are only a subset of the potential passthrough decoder
scenarios.

[PATCH 6.1 089/114] clk: ingenic: jz4760: Update M/N/OD calculation algorithm

[Greg Kroah-Hartman]

From: Paul Cercueil <paul@crapouillou.net>

commit ecfb9f404771dde909ce7743df954370933c3be2 upstream.

The previous algorithm was pretty broken.

- The inner loop had a '(m > m_max)' condition, and the value of 'm'
  would increase in each iteration;

- Each iteration would actually multiply 'm' by two, so it is not needed
  to re-compute the whole equation at each iteration;

- It would loop until (m & 1) == 0, which means it would loop at most
  once.

- The outer loop would divide the 'n' value by two at the end of each
  iteration. This meant that for a 12 MHz parent clock and a 1.2 GHz
  requested clock, it would first try n=12, then n=6, then n=3, then
  n=1, none of which would work; the only valid value is n=2 in this
  case.

Simplify this algorithm with a single for loop, which decrements 'n'
after each iteration, addressing all of the above problems.

[PATCH 6.1 093/114] nvdimm: Support sizeof(struct page) > MAX_STRUCT_PAGE_SIZE

[Greg Kroah-Hartman]

From: Dan Williams <dan.j.williams@intel.com>

commit c91d713630848460de8669e6570307b7e559863b upstream.

Commit 6e9f05dc66f9 ("libnvdimm/pfn_dev: increase MAX_STRUCT_PAGE_SIZE")

...updated MAX_STRUCT_PAGE_SIZE to account for sizeof(struct page)
potentially doubling in the case of CONFIG_KMSAN=y. Unfortunately this
doubles the amount of capacity stolen from user addressable capacity for
everyone, regardless of whether they are using the debug option. Revert
that change, mandate that MAX_STRUCT_PAGE_SIZE never exceed 64, but
allow for debug scenarios to proceed with creating debug sized page maps
with a compile option to support debug scenarios.

Note that this only applies to cases where the page map is permanent,
i.e. stored in a reservation of the pmem itself ("--map=dev" in "ndctl
create-namespace" terms). For the "--map=mem" case, since the allocation
is ephemeral for the lifespan of the namespace, there are no explicit
restriction. However, the implicit restriction, of having enough
available "System RAM" to store the page map for the typically large
pmem, still applies.

[PATCH 6.1 094/114] riscv: Fixup race condition on PG_dcache_clean in flush_icache_pte

[Greg Kroah-Hartman]

From: Guo Ren <guoren@linux.alibaba.com>

commit 950b879b7f0251317d26bae0687e72592d607532 upstream.

In commit 588a513d3425 ("arm64: Fix race condition on PG_dcache_clean
in __sync_icache_dcache()"), we found RISC-V has the same issue as the
previous arm64. The previous implementation didn't guarantee the correct
sequence of operations, which means flush_icache_all() hasn't been
called when the PG_dcache_clean was set. That would cause a risk of page
synchronization.

[PATCH 6.1 095/114] riscv: kprobe: Fixup misaligned load text

From: Guo Ren <guoren@linux.alibaba.com>

commit eb7423273cc9922ee2d05bf660c034d7d515bb91 upstream.

The current kprobe would cause a misaligned load for the probe point.
This patch fixup it with two half-word loads instead.

[PATCH 6.1 096/114] powerpc/64s/interrupt: Fix interrupt exit race with security mitigation switch

[Greg Kroah-Hartman]

From: Nicholas Piggin <npiggin@gmail.com>

commit 2ea31e2e62bbc4d11c411eeb36f1b02841dbcab1 upstream.

The RFI and STF security mitigation options can flip the
interrupt_exit_not_reentrant static branch condition concurrently with
the interrupt exit code which tests that branch.

Interrupt exit tests this condition to set MSR[EE|RI] for exit, then
again in the case a soft-masked interrupt is found pending, to recover
the MSR so the interrupt can be replayed before attempting to exit
again. If the condition changes between these two tests, the MSR and irq
soft-mask state will become corrupted, leading to warnings and possible
crashes. For example, if the branch is initially true then false,
MSR[EE] will be 0 but PACA_IRQ_HARD_DIS clear and EE may not get
enabled, leading to warnings in irq_64.c.

[PATCH 6.1 097/114] drm/amdgpu: Use the TGID for trace_amdgpu_vm_update_ptes

[Greg Kroah-Hartman]

From: Friedrich Vock <friedrich.vock@gmx.de>

commit e53448e0a1efa5133c7db78f1df1f4caf177676b upstream.

The pid field corresponds to the result of gettid() in userspace.
However, userspace cannot reliably attribute PTE events to processes
with just the thread id. This patch allows userspace to easily
attribute PTE update events to specific processes by comparing this
field with the result of getpid().

For attributing events to specific threads, the thread id is also
contained in the common fields of each trace event.

[PATCH 6.1 098/114] tracing: Fix TASK_COMM_LEN in trace event format file

[Greg Kroah-Hartman]

From: Yafang Shao <laoar.shao@gmail.com>

commit b6c7abd1c28a63ad633433d037ee15a1bc3023ba upstream.

After commit 3087c61ed2c4 ("tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN"),
the content of the format file under
/sys/kernel/tracing/events/task/task_newtask was changed from
  field:char comm[16];    offset:12;    size:16;    signed:0;
to
  field:char comm[TASK_COMM_LEN];    offset:12;    size:16;    signed:0;

John reported that this change breaks older versions of perfetto.
Then Mathieu pointed out that this behavioral change was caused by the
use of __stringify(_len), which happens to work on macros, but not on enum
labels. And he also gave the suggestion on how to fix it:
  :One possible solution to make this more robust would be to extend
  :struct trace_event_fields with one more field that indicates the length
  :of an array as an actual integer, without storing it in its stringified
  :form in the type, and do the formatting in f_show where it belongs.

The result as follows after this change,
$ cat /sys/kernel/tracing/events/task/task_newtask/format
        field:char comm[16];    offset:12;      size:16;        signed:0;

[PATCH 6.1 099/114] rtmutex: Ensure that the top waiter is always woken up

[Greg Kroah-Hartman]

From: Wander Lairson Costa <wander@redhat.com>

commit db370a8b9f67ae5f17e3d5482493294467784504 upstream.

Let L1 and L2 be two spinlocks.

Let T1 be a task holding L1 and blocked on L2. T1, currently, is the top
waiter of L2.

Let T2 be the task holding L2.

Let T3 be a task trying to acquire L1.

The following events will lead to a state in which the wait queue of L2
isn't empty, but no task actually holds the lock.

T1                T2                                  T3

T1 wakes up
T1 != top_waiter(L2)
schedule_rtlock()

If the deadline of T1 is updated before the call to update_prio(), and the
new deadline is greater than the deadline of the second top waiter, then
after the requeue, T1 is no longer the top waiter, and the wrong task is
woken up which will then go back to sleep because it is not the top waiter.

This can be reproduced in PREEMPT_RT with stress-ng:

while true; do
    stress-ng --sched deadline --sched-period 1000000000 \
    	    --sched-runtime 800000000 --sched-deadline \
    	    1000000000 --mmapfork 23 -t 20
done

A similar issue was pointed out by Thomas versus the cases where the top
waiter drops out early due to a signal or timeout, which is a general issue
for all regular rtmutex use cases, e.g. futex.

The problematic code is in rt_mutex_adjust_prio_chain():

    	// Save the top waiter before dequeue/enqueue
	prerequeue_top_waiter = rt_mutex_top_waiter(lock);

	rt_mutex_dequeue(lock, waiter);
	waiter_update_prio(waiter, task);
	rt_mutex_enqueue(lock, waiter);

	// Lock has no owner?
	if (!rt_mutex_owner(lock)) {
	   	// Top waiter changed
  ---->		if (prerequeue_top_waiter != rt_mutex_top_waiter(lock))
  ---->			wake_up_state(waiter->task, waiter->wake_state);

This only takes the case into account where @waiter is the new top waiter
due to the requeue operation.

But it fails to handle the case where @waiter is not longer the top
waiter due to the requeue operation.

Ensure that the new top waiter is woken up so in all cases so it can take
over the ownerless lock.

[PATCH 6.1 100/114] arm64: dts: meson-gx: Make mmc host controller interrupts level-sensitive

[Greg Kroah-Hartman]

From: Heiner Kallweit <hkallweit1@gmail.com>

commit 66e45351f7d6798751f98001d1fcd572024d87f0 upstream.

The usage of edge-triggered interrupts lead to lost interrupts under load,
see [0]. This was confirmed to be fixed by using level-triggered
interrupts.
The report was about SDIO. However, as the host controller is the same
for SD and MMC, apply the change to all mmc controller instances.

[PATCH 6.1 103/114] Fix page corruption caused by racy check in __free_pages

[Greg Kroah-Hartman]

From: David Chen <david.chen@nutanix.com>

commit 462a8e08e0e6287e5ce13187257edbf24213ed03 upstream.

When we upgraded our kernel, we started seeing some page corruption like
the following consistently:

  BUG: Bad page state in process ganesha.nfsd  pfn:1304ca
  page:0000000022261c55 refcount:0 mapcount:-128 mapping:0000000000000000 index:0x0 pfn:0x1304ca

  Call Trace:

   alloc_pages_current+0x87/0xf0
   skb_page_frag_refill+0x84/0x110
   ...

Sometimes, it would also show up as corruption in the free list pointer
and cause crashes.

After bisecting the issue, we found the issue started from commit
e320d3012d25 ("mm/page_alloc.c: fix freeing non-compound pages"):

	if (put_page_testzero(page))
		free_the_page(page, order);
	else if (!PageHead(page))
		while (order-- > 0)
			free_the_page(page + (1 << order), order);

So the problem is the check PageHead is racy because at this point we
already dropped our reference to the page.  So even if we came in with
compound page, the page can already be freed and PageHead can return
false and we will end up freeing all the tail pages causing double free.

[PATCH 6.1 104/114] arm64: efi: Force the use of SetVirtualAddressMap() on eMAG and Altra Max machines

[Greg Kroah-Hartman]

From: Darren Hart <darren@os.amperecomputing.com>

commit 190233164cd77115f8dea718cbac561f557092c6 upstream.

Commit 550b33cfd445 ("arm64: efi: Force the use of SetVirtualAddressMap()
on Altra machines") identifies the Altra family via the family field in
the type#1 SMBIOS record. eMAG and Altra Max machines are similarly
affected but not detected with the strict strcmp test.

The type1_family smbios string is not an entirely reliable means of
identifying systems with this issue as OEMs can, and do, use their own
strings for these fields. However, until we have a better solution,
capture the bulk of these systems by adding strcmp matching for "eMAG"
and "Altra Max".

[PATCH 6.1 108/114] drm/amdgpu/fence: Fix oops due to non-matching drm_sched init/fini

[Greg Kroah-Hartman]

From: Guilherme G. Piccoli <gpiccoli@igalia.com>

commit 5ad7bbf3dba5c4a684338df1f285080f2588b535 upstream.

Currently amdgpu calls drm_sched_fini() from the fence driver sw fini
routine - such function is expected to be called only after the
respective init function - drm_sched_init() - was executed successfully.

Happens that we faced a driver probe failure in the Steam Deck
recently, and the function drm_sched_fini() was called even without
its counter-part had been previously called, causing the following oops:

amdgpu: probe of 0000:04:00.0 failed with error -110
BUG: kernel NULL pointer dereference, address: 0000000000000090
PGD 0 P4D 0
Oops: 0002 [#1] PREEMPT SMP NOPTI
CPU: 0 PID: 609 Comm: systemd-udevd Not tainted 6.2.0-rc3-gpiccoli #338
Hardware name: Valve Jupiter/Jupiter, BIOS F7A0113 11/04/2022
RIP: 0010:drm_sched_fini+0x84/0xa0 [gpu_sched]
[...]
Call Trace:

 amdgpu_driver_release_kms+0x16/0x30 [amdgpu]
 devm_drm_dev_init_release+0x49/0x70
 [...]

To prevent that, check if the drm_sched was properly initialized for a
given ring before calling its fini counter-part.

Notice ideally we'd use sched.ready for that; such field is set as the latest
thing on drm_sched_init(). But amdgpu seems to "override" the meaning of such
field - in the above oops for example, it was a GFX ring causing the crash, and
the sched.ready field was set to true in the ring init routine, regardless of
the state of the DRM scheduler. Hence, we ended-up using sched.ops as per
Christian's suggestion [0], and also removed the no_scheduler check [1].

[PATCH 6.1 111/114] drm/amd/display: fix cursor offset on rotation 180

[Greg Kroah-Hartman]

From: Melissa Wen <mwen@igalia.com>

commit 49d0555976f0972af68397ed996375c135b38ba7 upstream.

Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.

Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247

The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.

[PATCH 6.1 112/114] drm/i915: Move fd_install after last use of fence

[Greg Kroah-Hartman]

From: Rob Clark <robdclark@chromium.org>

commit 251e8c5b1b1fadcc387a8e618c7437d330bdac3e upstream.

Because eb_composite_fence_create() drops the fence_array reference
after creation of the sync_file, only the sync_file holds a ref to the
fence.  But fd_install() makes that reference visable to userspace, so
it must be the last thing we do with the fence.
