Pull tracing fixes from Steven Rostedt: "A few tracing fixes: - Remove lockdown from tracefs itself and moved it to the trace directory. Have the open functions there do the lockdown checks. - Fix a few races with opening an instance file and the instance being deleted (Discovered during the lockdown updates). Kept separate from the clean up code such that they can be backported to stable easier. - Clean up and consolidated the checks done when opening a trace file, as there were multiple checks that need to be done, and it did not make sense having them done in each open instance. - Fix a regression in the record mcount code. - Small hw_lat detector tracer fixes. - A trace_pipe read fix due to not initializing trace_seq" * tag 'trace-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Initialize iter->seq after zeroing in tracing_read_pipe() tracing/hwlat: Don't ignore outer-loop duration when calculating max_latency tracing/hwlat: Report total time spent in all NMIs during the sample recordmcount: Fix nop_mcount() function tracing: Do not create tracefs files if tracefs lockdown is in effect tracing: Add locked_down checks to the open calls of files created for tracefs tracing: Add tracing_check_open_get_tr() tracing: Have trace events system open call tracing_open_generic_tr() tracing: Get trace_array reference for available_tracers files ftrace: Get a reference counter for the trace_array on filter files tracefs: Revert ccbd54ff ("tracefs: Restrict tracefs when the kernel is locked down") -

Merge tag 'iio-for-5.5a-take3' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of IIO new device support, cleanups and features for the 5.5 cycle Third version with the adis rework set dropped as better to just have a fresh version of that at some future date. The usual mixed backs of new device support being added to drivers, long term reworks continuing and little per driver cleanups and features. Also a few trivial counter subsystem tidy ups on behalf of William. Core new feature * Device label support. A long requested feature no one got around to implementing before. Allows DT based provision of a 'label' that identifies a device uniquely within a system. This differs from existing 'name' which is meant to be the part number. New device support * ingenic-adc - Support for the JZ4770 SoC ADC including bindings. * inv_mpu6050 - Add support for magnetometer in MPU925x parts. Fiddly to do as this is actually a separate device sitting inside the package, but with the master device being able to schedule reads etc. Will only run if the auxiliary bus is not in use for any other devices. Features * ad7192 - Userspace calibration controls to do zero and full scale. * st_lsm6dsx - Enable latched interrupts by default for sensors events with related clear. - Motion events and related wakeup source. This needed quite a bit of refactoring as well. Cleanups and minor features * ad7192 - sysfs ABI docs * ad7949 - Remove code to readback configuration word as driver never actually enabled it. - Fix incorrect xfer length. Not actually known to cause problems other than wasted bus usage. * adis16080 - Replace core mlock usage with local lock with more appropriate scope. * adis16130 - Remove pointless mlock usage. * adis16240 - Remove include of gpio.h as no gpio usage. * atlas-ph-sensor - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * bh1750 - Fix up a static compiler warning and make the code more readable. - yaml conversion of binding + MAINTAINERS entry. * bmp280 - Drop a stray newline. * cm36651 - Drop a redundant assignment * itg3200 - Alignment cleanup. * max31856 - Add missing of_node and parent references, useful to identify the device. * sc27xx_adc - Use devm_hwspin_lock_request_specific rather than local rolled version. * stm32-lptimer counter - kernel-doc warning. * stm32-timer counter - kernel-doc warning. - Alignment cleanup. * sx9500 - Improve logical ordering of buffer predisable / postenable functions.

The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. The iio_triggered_buffer_predisable() should be called last, to detach the poll func after the devices has been suspended. The position of iio_triggered_buffer_postenable() is correct. Note this is not stable material. It's a fix in the logical model rather fixing an actual bug. These are being tidied up throughout the subsystem to allow more substantial rework that was blocked by variations in how things were done.

There is no loop. So, it must be looping in the caller tracing_read_pipe() via the "waitagain" label. Crashdump analyze uncovered that iter->seq was completely zeroed at this point, including iter->seq.seq.size. It means that print_trace_line() was never able to print anything and there was no forward progress. The culprit seems to be in the code: /* reset all but tr, trace, and overruns */ memset(&iter->seq, 0, sizeof(struct trace_iterator) - offsetof(struct trace_iterator, seq)); It was added by the commit 53d0aa77 ("ftrace: add logic to record overruns"). It was v2.6.27-rc1. It was the time when iter->seq looked like: struct trace_seq { unsigned char buffer[PAGE_SIZE]; unsigned int len; }; There was no "size" variable and zeroing was perfectly fine. The solution is to reinitialize the structure after or without zeroing. Link: http://lkml.kernel.org/r/20191011142134.11997-1-pmladek@suse.comSigned-off-by:

max_latency is intended to record the maximum ever observed hardware latency, which may occur in either part of the loop (inner/outer). So we need to also consider the outer-loop sample when updating max_latency.

nmi_total_ts is supposed to record the total time spent in *all* NMIs that occur on the given CPU during the (active portion of the) sampling window. However, the code seems to be overwriting this variable for each NMI, thereby only recording the time spent in the most recent NMI. Fix it by accumulating the duration instead.

The removal of the longjmp code in recordmcount.c mistakenly made the return of make_nop() being negative an exit of nop_mcount(). It should not exit the routine, but instead just not process that part of the code. By exiting with an error code, it would cause the update of recordmcount to fail some files which would fail the build if ftrace function tracing was enabled.

Added various checks on open tracefs calls to see if tracefs is in lockdown mode, and if so, to return -EPERM. Note, the event format files (which are basically standard on all machines) as well as the enabled_functions file (which shows what is currently being traced) are not lockde down. Perhaps they should be, but it seems counter intuitive to lockdown information to help you know if the system has been modified.

Currently, most files in the tracefs directory test if tracing_disabled is set. If so, it should return -ENODEV. The tracing_disabled is called when tracing is found to be broken. Originally it was done in case the ring buffer was found to be corrupted, and we wanted to prevent reading it from crashing the kernel. But it's also called if a tracing selftest fails on boot. It's a one way switch. That is, once it is triggered, tracing is disabled until reboot. As most tracefs files can also be used by instances in the tracefs directory, they need to be carefully done. Each instance has a trace_array associated to it, and when the instance is removed, the trace_array is freed. But if an instance is opened with a reference to the trace_array, then it requires looking up the trace_array to get its ref counter (as there could be a race with it being deleted and the open itself). Once it is found, a reference is added to prevent the instance from being removed (and the trace_array associated with it freed). Combine the two checks (tracing_disabled and trace_array_get()) into a single helper function. This will also make it easier to add lockdown to tracefs later.

Instead of having the trace events system open call open code the taking of the trace_array descriptor (with trace_array_get()) and then calling trace_open_generic(), have it use the tracing_open_generic_tr() that does the combination of the two. This requires making tracing_open_generic_tr() global. Signed-off-by: -

As instances may have different tracers available, we need to look at the trace_array descriptor that shows the list of the available tracers for the instance. But there's a race between opening the file and an admin deleting the instance. The trace_array_get() needs to be called before accessing the trace_array.

The ftrace set_ftrace_filter and set_ftrace_notrace files are specific for an instance now. They need to take a reference to the instance otherwise there could be a race between accessing the files and deleting the instance. It wasn't until the :mod: caching where these file operations started referencing the trace_array directly.

It appears that the allocation of the proxy_ops and then freeing it in the destroy_inode callback, is causing havoc with the memory system. Reading the documentation about destroy_inode and talking with Linus about this, this is buggy and wrong. When defining the destroy_inode() method, it is expected that the destroy_inode() will also free the inode, and not just the extra allocations done in the creation of the inode. The faulty commit causes a memory leak of the inode data structure when they are deleted. Instead of allocating the proxy_ops (and then having to free it) the checks should be done by the open functions themselves, and not hack into the tracefs directory. First revert the tracefs updates for locked_down and then later we can add the locked_down checks in the kernel/trace files.

Pull USB fixes from Greg KH: "Here are a lot of small USB driver fixes for 5.4-rc3. syzbot has stepped up its testing of the USB driver stack, now able to trigger fun race conditions between disconnect and probe functions. Because of that we have a lot of fixes in here from Johan and others fixing these reported issues that have been around since almost all time. We also are just deleting the rio500 driver, making all of the syzbot bugs found in it moot as it turns out no one has been using it for years as there is a userspace version that is being used instead. There are also a number of other small fixes in here, all resolving reported issues or regressions.
