Subject: [PATCH AUTOSEL 5.14 01/18] KVM: arm64: Report corrupted refcount at EL2

From: Quentin Perret <[email protected]>

[ Upstream commit 7615c2a514788559c6684234b8fc27f3a843c2c6 ]

Some of the refcount manipulation helpers used at EL2 are instrumented
to catch a corrupted state, but not all of them are treated equally. Let's
make things more consistent by instrumenting hyp_page_ref_dec_and_test()
as well.

Subject: [PATCH AUTOSEL 5.14 03/18] ASoC: cs42l42: Ensure 0dB full scale volume is used for headsets

From: Stefan Binding <[email protected]>

[ Upstream commit aa18457c4af7a9dad1f2b150b11beae1d8ab57aa ]

Ensure the default 0dB playback path is always used.

The code that set FULL_SCALE_VOL based on LOAD_DET_RCSTAT was
spurious, and resulted in a -6dB attenuation being accidentally
inserted into the playback path.

Subject: [PATCH AUTOSEL 5.14 04/18] scsi: core: Put LLD module refcnt after SCSI device is released

From: Ming Lei <[email protected]>

[ Upstream commit f2b85040acec9a928b4eb1b57a989324e8e38d3f ]

SCSI host release is triggered when SCSI device is freed. We have to make
sure that the low-level device driver module won't be unloaded before SCSI
host instance is released because shost->hostt is required in the release
handler.

Make sure to put LLD module refcnt after SCSI device is released.

Fixes a kernel panic of 'BUG: unable to handle page fault for address'
reported by Changhui and Yi.

Subject: [PATCH AUTOSEL 5.14 05/18] ALSA: hda/realtek: Fixes HP Spectre x360 15-eb1xxx speakers

From: Davide Baldo <[email protected]>

[ Upstream commit d94befbb5ae379f6dfd4fa6d460eacc09fa7b9c3 ]

In laptop 'HP Spectre x360 Convertible 15-eb1xxx/8811' both front and
rear speakers are silent, this patch fixes that by overriding the pin
layout and by initializing the amplifier which needs a GPIO pin to be
set to 1 then 0, similar to the existing HP Spectre x360 14 model.

In order to have volume control, both front and rear speakers were
forced to use the DAC1.

This patch also correctly map the mute LED but since there is no
microphone on/off switch exposed by the alsa subsystem it never turns
on by itself.

There are still known audio issues in this laptop: headset microphone
doesn't work, the button to mute/unmute microphone is not yet mapped,
the LED of the mute/unmute speakers doesn't seems to be exposed via
GPIO and never turns on.

Subject: [PATCH AUTOSEL 5.14 06/18] ptp: fix error print of ptp_kvm on X86_64 platform

From: Kele Huang <[email protected]>

[ Upstream commit c2402d43d183b11445aed921e7bebcd47ef222f1 ]

Commit a86ed2cfa13c5 ("ptp: Don't print an error if ptp_kvm is not supported")
fixes the error message print on ARM platform by only concerning about
the case that the error returned from kvm_arch_ptp_init() is not -EOPNOTSUPP.
Although the ARM platform returns -EOPNOTSUPP if ptp_kvm is not supported
while X86_64 platform returns -KVM_EOPNOTSUPP, both error codes share the
same value 95.

Actually kvm_arch_ptp_init() on X86_64 platform can return three kinds of
errors (-KVM_ENOSYS, -KVM_EOPNOTSUPP and -KVM_EFAULT). The problem is that
-KVM_EOPNOTSUPP is masked out and -KVM_EFAULT is ignored among them.
This patch fixes this by returning them to ptp_kvm_init() respectively.

Subject: [PATCH AUTOSEL 5.14 11/18] scsi: qla2xxx: Fix unmap of already freed sgl

From: Dmitry Bogdanov <[email protected]>

[ Upstream commit 4a8f71014b4d56c4fb287607e844c0a9f68f46d9 ]

The sgl is freed in the target stack in target_release_cmd_kref() before
calling qlt_free_cmd() but there is an unmap of sgl in qlt_free_cmd() that
causes a panic if sgl is not yet DMA unmapped:

NIP dma_direct_unmap_sg+0xdc/0x180
LR dma_direct_unmap_sg+0xc8/0x180
Call Trace:
ql_dbg_prefix+0x68/0xc0 [qla2xxx] (unreliable)
dma_unmap_sg_attrs+0x54/0xf0
qlt_unmap_sg.part.19+0x54/0x1c0 [qla2xxx]

transport_generic_free_cmd+0x6c/0x1b0 [target_core_mod]
tcm_qla2xxx_complete_free+0x6c/0x90 [tcm_qla2xxx]

The sgl may be left unmapped in error cases of response sending. For
instance, qlt_rdy_to_xfer() maps sgl and exits when session is being
deleted keeping the sgl mapped.

This patch removes use-after-free of the sgl and ensures that the sgl is
unmapped for any command that was not sent to firmware.

Subject: [PATCH AUTOSEL 5.14 14/18] vrf: Revert "Reset skb conntrack connection..."

From: Eugene Crosser <[email protected]>

[ Upstream commit 55161e67d44fdd23900be166a81e996abd6e3be9 ]

This reverts commit 09e856d54bda5f288ef8437a90ab2b9b3eab83d1.

When an interface is enslaved in a VRF, prerouting conntrack hook is
called twice: once in the context of the original input interface, and
once in the context of the VRF interface. If no special precausions are
taken, this leads to creation of two conntrack entries instead of one,
and breaks SNAT.

Commit above was intended to avoid creation of extra conntrack entries
when input interface is enslaved in a VRF. It did so by resetting
conntrack related data associated with the skb when it enters VRF context.

However it breaks netfilter operation. Imagine a use case when conntrack
zone must be assigned based on the original input interface, rather than
VRF interface (that would make original interfaces indistinguishable). One
could create netfilter rules similar to these:

chain rawprerouting {
type filter hook prerouting priority raw;
iif realiface1 ct zone set 1 return
iif realiface2 ct zone set 2 return
}

This works before the mentioned commit, but not after: zone assignment
is "forgotten", and any subsequent NAT or filtering that is dependent
on the conntrack zone does not work.

Here is a reproducer script that demonstrates the difference in behaviour.

==========
#!/bin/sh

# This script demonstrates unexpected change of nftables behaviour
# caused by commit 09e856d54bda5f28 ""vrf: Reset skb conntrack
# connection on VRF rcv"
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=09e856d54bda5f288ef8437a90ab2b9b3eab83d1
#
# Before the commit, it was possible to assign conntrack zone to a
# packet (or mark it for `notracking`) in the prerouting chanin, raw
# priority, based on the `iif` (interface from which the packet
# arrived).
# After the change, # if the interface is enslaved in a VRF, such
# assignment is lost. Instead, assignment based on the `iif` matching
# the VRF master interface is honored. Thus it is impossible to
# distinguish packets based on the original interface.
#
# This script demonstrates this change of behaviour: conntrack zone 1
# or 2 is assigned depending on the match with the original interface
# or the vrf master interface. It can be observed that conntrack entry
# appears in different zone in the kernel versions before and after
# the commit.

Subject: [PATCH AUTOSEL 5.14 15/18] sfc: Export fibre-specific supported link modes

From: Erik Ekman <[email protected]>

[ Upstream commit c62041c5baa9ded3bc6fd38d3f724de70683b489 ]

The 1/10GbaseT modes were set up for cards with SFP+ cages in
3497ed8c852a5 ("sfc: report supported link speeds on SFP connections").
10GbaseT was likely used since no 10G fibre mode existed.

The missing fibre modes for 1/10G were added to ethtool.h in 5711a9822144
("net: ethtool: add support for 1000BaseX and missing 10G link modes")
shortly thereafter.

The user guide available at https://support-nic.xilinx.com/wp/drivers
lists support for the following cable and transceiver types in section 2.9:
- QSFP28 100G Direct Attach Cables
- QSFP28 100G SR Optical Transceivers (with SR4 modules listed)
- SFP28 25G Direct Attach Cables
- SFP28 25G SR Optical Transceivers
- QSFP+ 40G Direct Attach Cables
- QSFP+ 40G Active Optical Cables
- QSFP+ 40G SR4 Optical Transceivers
- QSFP+ to SFP+ Breakout Direct Attach Cables
- QSFP+ to SFP+ Breakout Active Optical Cables
- SFP+ 10G Direct Attach Cables
- SFP+ 10G SR Optical Transceivers
- SFP+ 10G LR Optical Transceivers
- SFP 1000BASE‐T Transceivers
- 1G Optical Transceivers
(From user guide issue 28. Issue 16 which also includes older cards like
SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.)

Regarding SFP+ 10GBASE‐T transceivers the latest guide says:
"Solarflare adapters do not support 10GBASE‐T transceiver modules."

Tested using SFN5122F-R7 (with 2 SFP+ ports). Supported link modes do not change
depending on module used (tested with 1000BASE-T, 1000BASE-BX10, 10GBASE-LR).

Subject: [PATCH AUTOSEL 5.14 02/18] ASoC: soc-core: fix null-ptr-deref in snd_soc_del_component_unlocked()

From: Yang Yingliang <[email protected]>

[ Upstream commit c448b7aa3e66042fc0f849d9a0fb90d1af82e948 ]

'component' is allocated in snd_soc_register_component(), but component->list
is not initalized, this may cause snd_soc_del_component_unlocked() deref null
ptr in the error handing case.

KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]
RIP: 0010:__list_del_entry_valid+0x81/0xf0

Fix by adding INIT_LIST_HEAD() to snd_soc_component_initialize().
