[PATCH AUTOSEL 5.10 01/13] ASoC: soc-core: fix null-ptr-deref in snd_soc_del_component_unlocked()
From: Yang Yingliang yangyingliang@huawei.com
[ 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.

[ 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.

[ 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.

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:

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.

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/?i... # # 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.

[ 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). Before:

Use pci_info instead to avoid unnamed/uninitialized noise:
