2022-03-23Merge tag 'trace-v5.18' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - New user_events interface. User space can register an event with the kernel describing the format of the event. Then it will receive a byte in a page mapping that it can check against. A privileged task can then enable that event like any other event, which will change the mapped byte to true, telling the user space application to start writing the event to the tracing buffer. - Add new "ftrace_boot_snapshot" kernel command line parameter. When set, the tracing buffer will be saved in the snapshot buffer at boot up when the kernel hands things over to user space. This will keep the traces that happened at boot up available even if user space boot up has tracing as well. - Have TRACE_EVENT_ENUM() also update trace event field type descriptions. Thus if a static array defines its size with an enum, the user space trace event parsers can still know how to parse that array. - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the TRACE_EVENT() macro, but will attach to an existing tracepoint. This will make one tracepoint be able to trace different content and not be stuck at only what the original TRACE_EVENT() macro exports. - Fixes to tracing error logging. - Better saving of cmdlines to PIDs when tracing (use the wakeup events for mapping). * tag 'trace-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (30 commits) tracing: Have type enum modifications copy the strings user_events: Add trace event call as root for low permission cases tracing/user_events: Use alloc_pages instead of kzalloc() for register pages tracing: Add snapshot at end of kernel boot up tracing: Have TRACE_DEFINE_ENUM affect trace event types as well tracing: Fix strncpy warning in trace_events_synth.c user_events: Prevent dyn_event delete racing with ioctl add/delete tracing: Add TRACE_CUSTOM_EVENT() macro tracing: Move the defines to create TRACE_EVENTS into their own files tracing: Add sample code for custom trace events tracing: Allow custom events to be added to the tracefs directory tracing: Fix last_cmd_set() string management in histogram code user_events: Fix potential uninitialized pointer while parsing field tracing: Fix allocation of last_cmd in last_cmd_set() user_events: Add documentation file user_events: Add sample code for typical usage user_events: Add self-test for validator boundaries user_events: Add self-test for perf_event integration user_events: Add self-test for dynamic_events integration user_events: Add self-test for ftrace integration ...

2022-03-23drivers: ethernet: cpsw: fix panic when interrupt coaleceing is set via ethtoolSondhauß, Jan
cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync when successful. pm_runtime_get_sync returns -error code on failure and 0 on successful resume but also 1 when the device is already active. So the common case for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls to pm_runtime_put in the call-chain so that pm_runtime_put is called one too many times and as result leaving the cpsw dev behind suspended. The suspended cpsw dev leads to an access violation later on by different parts of the cpsw driver. Fix this by calling the return-friendly pm_runtime_resume_and_get function.

2022-03-23ice: don't allow to run ice_send_event_to_aux() in atomic ctxAlexander Lobakin
ice_send_event_to_aux() eventually descends to mutex_lock() (-> might_sched()), so it must not be called under non-task context. However, at least two fixes have happened already for the bug splats occurred due to this function being called from atomic context. To make the emergency landings softer, bail out early when executed in non-task context emitting a warn splat only once. This way we trade some events being potentially lost for system stability and avoid any related hangs and crashes.

All packets on ingress (except for jumbo) are terminated with a 4-bytes CRC checksum. It's the responsability of the driver to strip those 4 bytes. Unfortunately a change dating back to March 2017 re-shuffled some code and made the CRC stripping code effectively dead.

If a trace event has in its TP_printk(): "%*.s", len, len ? __get_str(string) : NULL It is perfectly valid if len is zero and passing in the NULL. Unfortunately, the runtime string check at time of reading the trace sees the NULL and flags it as a bad string and produces a WARN_ON(). Handle this case by passing into the test function if the format has an asterisk (star) and if so, if the length is zero, then mark it as safe.

2022-03-23mfd: Use platform_get_irq() to get the interruptMinghao Chi (CGEL ZTE)
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ) for requesting IRQ's resources any more, as they can be not ready yet in case of DT-booting. platform_get_irq() instead is a recommended way for getting IRQ even if it was not retrieved earlier. It also makes code simpler because we're getting "int" value right away and no conversion from resource to int is required. The print function dev_err() is redundant because platform_get_irq() already prints an error.

2022-03-23mfd: arizona-spi: Add Android board ACPI table handlingHans de Goede
x86/ACPI boards with an arizona WM5102 codec ship with either Windows or Android as factory installed OS. The ACPI fwnode for the codec on Android boards misses 2 things compared to the Windows boards (this is hardcoded in the Android board kernels): 1. There is no CLKE ACPI method to enabe the 32 KHz clock the codec needs for jack-detection. 2. The GPIOs used by the codec are not listed in the fwnode for the codec. The ACPI tables on x86/ACPI boards shipped with Android being incomplete happens a lot. The special drivers/platform/x86/x86-android-tablets.c module contains DMI based per model handling to compensate for this. This module will enable the 32KHz clock through the pinctrl framework to fix 1. and it will also register a gpio-lookup table for all GPIOs needed by the codec + machine driver, including the GPIOs coming from the codec itself. Add an arizona_spi_acpi_android_probe() function which waits for the x86-android-tablets to have set things up before continue with probing the arizona WM5102 codec.

2022-03-23ARM: configs: multi_v5: Enable Allwinner F1C100Andre Przywara
The Kconfig symbols required for the Allwinner F1C100 (MACH_SUNIV) are currently not selected by any defconfig. sunxi_defconfig only covers the v7 SoCs, but the F1C100s is ARMv5, so we cannot share a single image. Add the required symbols to multi_v5_defconfig, to give people some sane default config when playing around with this chip. This is probably more important as there are surely not many distros out there supporting ARMv5 out of the box. This allows my LicheePi Nano board to boot to a busybox prompt.

2022-03-22net: dsa: fix missing host-filtered multicast addressesVladimir Oltean
DSA ports are stacked devices, so they use dev_mc_add() to sync their address list to their lower interface (DSA master). But they are also hardware devices, so they program those addresses to hardware using the __dev_mc_add() sync and unsync callbacks. Unfortunately both cannot work at the same time, and it seems that the multicast addresses which are already present on the DSA master, like 33:33:00:00:00:01 (added by addrconf.c as in6addr_linklocal_allnodes) are synced to the master via dev_mc_sync(), but not to hardware by __dev_mc_sync(). This happens because both the dev_mc_sync() -> __hw_addr_sync_one() code path, as well as __dev_mc_sync() -> __hw_addr_sync_dev(), operate on the same variable: ha->sync_cnt, in a way that causes the "sync" method (dsa_slave_sync_mc) to no longer be called. To fix the issue we need to work with the API in the way in which it was intended to be used, and therefore, call dev_uc_add() and friends for each individual hardware address, from the sync and unsync callbacks.
