ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE

2022-02-16T11:52:54Z

commit dc0075ba7f387fe4c48a8c674b11ab6f374a6acc upstream. Commit 4a9af6cac050 ("ACPI: EC: Rework flushing of EC work while suspended to idle") made acpi_ec_dispatch_gpe() check pm_wakeup_pending(), but that is before canceling the SCI wakeup, so pm_wakeup_pending() is always true. This causes the loop in acpi_ec_dispatch_gpe() to always terminate after one iteration which may not be correct. Address this issue by canceling the SCI wakeup earlier, from acpi_ec_dispatch_gpe() itself.

perf: Fix list corruption in perf_cgroup_switch()

2022-02-16T11:52:53Z

commit 5f4e5ce638e6a490b976ade4a40017b40abb2da0 upstream. There's list corruption on cgrp_cpuctx_list. This happens on the following path: perf_cgroup_switch: list_for_each_entry(cgrp_cpuctx_list) cpu_ctx_sched_in ctx_sched_in ctx_pinned_sched_in merge_sched_in perf_cgroup_event_disable: remove the event from the list Use list_for_each_entry_safe() to allow removing an entry during iteration.

scsi: lpfc: Remove NVMe support if kernel has NVME_FC disabled

2022-02-16T11:52:53Z

commit c80b27cfd93ba9f5161383f798414609e84729f3 upstream. The driver is initiating NVMe PRLIs to determine device NVMe support. This should not be occurring if CONFIG_NVME_FC support is disabled. Correct this by changing the default value for FC4 support. Currently it defaults to FCP and NVMe. With change, when NVME_FC support is not enabled in the kernel, the default value is just FCP.

hwmon: (dell-smm) Speed up setting of fan speed

2022-02-16T11:52:53Z

commit c0d79987a0d82671bff374c07f2201f9bdf4aaa2 upstream. When setting the fan speed, i8k_set_fan() calls i8k_get_fan_status(), causing an unnecessary SMM call since from the two users of this function, only i8k_ioctl_unlocked() needs to know the new fan status while dell_smm_write() ignores the new fan status. Since SMM calls can be very slow while also making error reporting difficult for dell_smm_write(), remove the function call from i8k_set_fan() and call it separately in i8k_ioctl_unlocked(). Tested on a Dell Inspiron 3505.

seccomp: Invalidate seccomp mode to catch death failures

2022-02-16T11:52:53Z

commit 495ac3069a6235bfdf516812a2a9b256671bbdf9 upstream. If seccomp tries to kill a process, it should never see that process again. To enforce this proactively, switch the mode to something impossible. If encountered: WARN, reject all syscalls, and attempt to kill the process again even harder.

USB: serial: ch341: add support for GW Instek USB2.0-Serial devices

2022-02-16T11:52:53Z

commit fa77ce201f7f2d823b07753575122d1ae5597fbe upstream. Programmable lab power supplies made by GW Instek, such as the GPP-2323, have a USB port exposing a serial port to control the device. Stringing the supplied Windows driver, references to the ch341 chip are found. Binding the existing ch341 driver to the VID/PID of the GPP-2323 ("GW Instek USB2.0-Serial" as per the USB product name) works out of the box, communication and control is now possible. This patch should work with any GPP series power supply due to similarities in the product line.
