From: Terry Junge linuxhid@cosmicgizmosystems.com
commit 486f6205c233da1baa309bde5f634eb1f8319a33 upstream.
Many Poly/Plantronics headset families name the feature, input, and/or output units in a such a way to produce control names that are not recognized by user space. As such, the volume and mute events do not get routed to the headset's audio controls.
As an example from a product family:
The microphone mute control is named Headset Microphone Capture Switch and the headset volume control is named Headset Earphone Playback Volume
The quirk fixes these to become Headset Capture Switch Headset Playback Volume

commit 9821709af892be9fbf4ee9a50b2f3e0604295ce0 upstream.
Add mapping for headset mute key events.
Remove PLT_QUIRK_DOUBLE_VOLUME_KEYS quirk and made it generic. The quirk logic did not keep track of the actual previous key so any key event occurring in less than or equal to 5ms was ignored.
Remove PLT_QUIRK_FOLLOWED_OPPOSITE_VOLUME_KEYS quirk. It had the same logic issue as the double key quirk and was actually masking the as designed behavior of most of the headsets. It's occurrence should be minimized with the ALSA control naming quirk that is part of the patch set.

commit bf2986fcf82a449441f9ee4335df19be19e83970 upstream.
When MPOA_cache_impos_rcvd() receives the msg, it can trigger Null Pointer Dereference Vulnerability if both entry and holding_time are NULL. Because there is only for the situation where entry is NULL and holding_time exists, it can be passed when both entry and holding_time are NULL. If these are NULL, the entry will be passd to eg_cache_put() as parameter and it is referenced by entry->use code in it.

commit 169f9102f9198b04afffa6164372a4ba4070f412 upstream.
Under PAN emulation when dumping backtraces from things like the LKDTM EXEC_USERSPACE test[1], a double fault (which would hang a CPU) would happen because of dump_instr() attempting to read a userspace address. Make sure copy_from_kernel_nofault() does not attempt this any more.

commit bc068194f548ef1f230d96c4398046bf59165992 upstream.
[Why] Observe after suspend/resme, we can't light up mst monitors under specific mst hub. The reason is that driver still writes DPCD DP_MSTM_CTRL after LT. It's forbidden even we write the same value for that dpcd register.
[How] We already resume the mst branch device dpcd settings during resume_mst_branch_status(). Leverage drm_dp_mst_topology_queue_probe() to only probe the topology, not calling drm_dp_mst_topology_mgr_resume() which will set DP_MSTM_CTRL as well.

commit 800f1059c99e2b39899bdc67a7593a7bea6375d8 upstream.
Watermarks are initialized during the postcore initcall. Until then, all watermarks are set to zero. This causes cond_accept_memory() to incorrectly skip memory acceptance because a watermark of 0 is always met.
This can lead to a premature OOM on boot.
To ensure progress, accept one MAX_ORDER page if the watermark is zero.

From: Maxim Mikityanskiy maxtram95@gmail.com
commit 932b32ffd7604fb00b5c57e239a3cc4d901ccf6e upstream.
nf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets to restore the original 5-tuple in case of SNAT, to be able to find the right socket (if any). Then socket_match() can correctly check whether the socket was transparent.
However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks this conntrack lookup, making xt_socket fail to match on the socket when the packet was SNATed. Add the same logic to nf_sk_lookup_slow_v6.
IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, as pods' addresses are in the fd00::/8 ULA subnet and need to be replaced with the node's external address. Cilium leverages Envoy to enforce L7 policies, and Envoy uses transparent sockets. Cilium inserts an iptables prerouting rule that matches on `-m socket --transparent` and redirects the packets to localhost, but it fails to match SNATed IPv6 packets due to that missing conntrack lookup.

commit 8744dcd4fc7800de2eb9369410470bb2930d4c14 upstream.
In case the stm32_lptim_set_enable_state() fails to update CMP and ARR, a timeout error is raised, by regmap_read_poll_timeout. It may happen, when the lptimer runs on a slow clock, and the clock is gated only few times during the polling.
Badly, when this happen, STM32_LPTIM_ENABLE in CR register has been set. So the 'enable' state in sysfs wrongly lies on the counter being correctly enabled, due to CR is read as one in stm32_lptim_is_enabled().
To fix both issues: - enable the clock before writing CMP, ARR and polling ISR bits. It will avoid the possible timeout error. - clear the ENABLE bit in CR and disable the clock in the error path.

From: Dominique Martinet dominique.martinet@atmark-techno.com
commit 2ea396448f26d0d7d66224cb56500a6789c7ed07 upstream.
commit 8a7d12d674ac ("net: usb: usbnet: fix name regression") assumed that local addresses always came from the kernel, but some devices hand out local mac addresses so we ended up with point-to-point devices with a mac set by the driver, renaming to eth%d when they used to be named usb%d.
Userspace should not rely on device name, but for the sake of stability restore the local mac address check portion of the naming exception: point to point devices which either have no mac set by the driver or have a local mac handed out by the driver will keep the usb%d name.
(some USB LTE modems are known to hand out a stable mac from the locally administered range; that mac appears to be random (different for mulitple devices) and can be reset with device-specific commands, so while such devices would benefit from getting a OUI reserved, we have to deal with these and might as well preserve the existing behavior to avoid breaking fragile openwrt configurations and such on upgrade.)

commit a7bb96b18864225a694e3887ac2733159489e4b0 upstream.
Fix potential dereferencing of ERR_PTR() in find_format_by_pix() and uvc_v4l2_enum_format().
Fix the following smatch errors:
drivers/usb/gadget/function/uvc_v4l2.c:124 find_format_by_pix() error: 'fmtdesc' dereferencing possible ERR_PTR()
drivers/usb/gadget/function/uvc_v4l2.c:392 uvc_v4l2_enum_format() error: 'fmtdesc' dereferencing possible ERR_PTR()
Also, fix similar issue in uvc_v4l2_try_format() for potential dereferencing of ERR_PTR().
