Author: Dhruv Deshpande <[email protected]> Date: Mon Mar 17 08:56:53 2025 +0000 ALSA: hda/realtek: Support mute LED on HP Laptop 15s-du3xxx commit 35ef1c79d2e09e9e5a66e28a66fe0df4368b0f3d upstream. The mute LED on this HP laptop uses ALC236 and requires a quirk to function. This patch enables the existing quirk for the device. Tested on my laptop and the LED behaviour works as intended.

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 Signed-off-by: Terry Junge <[email protected]> Reviewed-by: Takashi Iwai <[email protected]> Cc: [email protected] Signed-off-by: Jiri Kosina <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

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.

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.

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.

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.)

Author: Maxim Mikityanskiy <[email protected]> Date: Tue Mar 18 18:15:16 2025 +0200 netfilter: socket: Lookup orig tuple for IPv6 SNAT 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.

Author: Sherry Sun <[email protected]> Date: Wed Mar 12 10:25:03 2025 +0800 tty: serial: fsl_lpuart: disable transmitter before changing RS485 related registers commit f5cb528d6441eb860250a2f085773aac4f44085e upstream. According to the LPUART reference manual, TXRTSE and TXRTSPOL of MODIR register only can be changed when the transmitter is disabled. So disable the transmitter before changing RS485 related registers and re-enable it after the change is done.
