2023-03-23pwm: Zero-initialize the pwm_state passed to driver's .get_state()Uwe Kleine-König
This is just to ensure that .usage_power is properly initialized and doesn't contain random stack data. The other members of struct pwm_state should get a value assigned in a successful call to .get_state(). So in the absence of bugs in driver implementations, this is only a safe-guard and no fix.

2023-03-23pwm: meson: Explicitly set .polarity in .get_state()Uwe Kleine-König
The driver only supports normal polarity. Complete the implementation of .get_state() by setting .polarity accordingly. This fixes a regression that was possible since commit c73a3107624d ("pwm: Handle .get_state() failures") which stopped to zero-initialize the state passed to the .get_state() callback. This was reported at https://forum.odroid.com/viewtopic.php?f=177&t=46360 . While this was an unintended side effect, the real issue is the driver's callback not setting the polarity. There is a complicating fact, that the .apply() callback fakes support for inversed polarity. This is not (and cannot) be matched by .get_state(). As fixing this isn't easy, only point it out in a comment to prevent authors of other drivers from copying that approach.

[Why] For engines not supporting soft reset, i.e. VCN, there will be a failed ib test before mode 1 reset during asic reset. The fences in this case are never signaled and next time when we try to free the sa_bo, kernel will hang. [How] During pre_asic_reset, driver will clear job fences and afterwards the fences' refcount will be reduced to 1. For drm_sched_jobs it will be released in job_free_cb, and for non-sched jobs like ib_test, it's meant to be released in sa_bo_free but only when the fences are signaled. So we have to force signal the non_sched bad job's fence during pre_asic_reset or the clear is not complete.

2023-03-23vhost: use vhost_tasks for worker threadsMike Christie
For vhost workers we use the kthread API which inherit's its values from and checks against the kthreadd thread. This results in the wrong RLIMITs being checked, so while tools like libvirt try to control the number of threads based on the nproc rlimit setting we can end up creating more threads than the user wanted. This patch has us use the vhost_task helpers which will inherit its values/checks from the thread that owns the device similar to if we did a clone in userspace. The vhost threads will now be counted in the nproc rlimits. And we get features like cgroups and mm sharing automatically, so we can remove those calls.

2023-03-23vhost_task: Allow vhost layer to use copy_processMike Christie
Qemu will create vhost devices in the kernel which perform network, SCSI, etc IO and management operations from worker threads created by the kthread API. Because the kthread API does a copy_process on the kthreadd thread, the vhost layer has to use kthread_use_mm to access the Qemu thread's memory and cgroup_attach_task_all to add itself to the Qemu thread's cgroups, and it bypasses the RLIMIT_NPROC limit which can result in VMs creating more threads than the admin expected. This patch adds a new struct vhost_task which can be used instead of kthreads. They allow the vhost layer to use copy_process and inherit the userspace process's mm and cgroups, the task is accounted for under the userspace's nproc count and can be seen in its process tree, and other features like namespaces work and are inherited by default.

2023-03-23efi/libstub: Use relocated version of kernel's struct screen_infoArd Biesheuvel
In some cases, we expose the kernel's struct screen_info to the EFI stub directly, so it gets populated before even entering the kernel. This means the early console is available as soon as the early param parsing happens, which is nice. It also means we need two different ways to pass this information, as this trick only works if the EFI stub is baked into the core kernel image, which is not always the case. Huacai reports that the preparatory refactoring that was needed to implement this alternative method for zboot resulted in a non-functional efifb earlycon for other cases as well, due to the reordering of the kernel image relocation with the population of the screen_info struct, and the latter now takes place after copying the image to its new location, which means we copy the old, uninitialized state. So let's ensure that the same-image version of alloc_screen_info() produces the correct screen_info pointer, by taking the displacement of the loaded image into account.

2023-03-22net: dsa: mt7530: move enabling disabling core clock to mt7530_pll_setup()Arınç ÜNAL
Split the code that enables and disables TRGMII clocks and core clock. Move enabling and disabling core clock to mt7530_pll_setup() as it's supposed to be run there. Add 20 ms delay before enabling the core clock as seen on the U-Boot MediaTek ethernet driver. Change the comment for enabling and disabling TRGMII clocks as the code seems to affect both TXC and RXC.

2023-03-22net: asix: fix modprobe "sysfs: cannot create duplicate filename"Grant Grundler
"modprobe asix ; rmmod asix ; modprobe asix" fails with: sysfs: cannot create duplicate filename \ '/devices/virtual/mdio_bus/usb-003:004' Issue was originally reported by Anton Lundin on 2022-06-22 (link below). Chrome OS team hit the same issue in Feb, 2023 when trying to find work arounds for other issues with AX88172 devices. The use of devm_mdiobus_register() with usbnet devices results in the MDIO data being associated with the USB device. When the asix driver is unloaded, the USB device continues to exist and the corresponding "mdiobus_unregister()" is NOT called until the USB device is unplugged or unauthorized. So the next "modprobe asix" will fail because the MDIO phy sysfs attributes still exist. The 'easy' (from a design PoV) fix is to use the non-devm variants of mdiobus_* functions and explicitly manage this use in the asix_bind and asix_unbind function calls. I've not explored trying to fix usbnet initialization so devm_* stuff will work.

2023-03-22gve: Cache link_speed value from deviceJoshua Washington
The link speed is never changed for the uptime of a VM, and the current implementation sends an admin queue command for each call. Admin queue command invocations have nontrivial overhead (e.g., VM exits), which can be disruptive to users if triggered frequently. Our telemetry data shows that there are VMs that make frequent calls to this admin queue command. Caching the result of the original admin queue command would eliminate the need to send multiple admin queue commands on subsequent calls to retrieve link speed.

2023-03-22net: enetc: fix aggregate RMON counters not showing the rangesVladimir Oltean
When running "ethtool -S eno0 --groups rmon" without an explicit "--src emac|pmac" argument, the kernel will not report rx-rmon-etherStatsPkts64to64Octets, rx-rmon-etherStatsPkts65to127Octets, etc. This is because on ETHTOOL_MAC_STATS_SRC_AGGREGATE, we do not populate the "ranges" argument. ocelot_port_get_rmon_stats() does things differently and things work there. I had forgotten to make sure that the code is structured the same way in both drivers, so do that now.
