Voltage constraints on vccio_sd are invalid. They don't match the voltages that LDO9 can generate, and this causes rk808-regulator driver to fail to probe with -EINVAL when it tries to apply the constraints during boot. Fix the constraints to something that LDO9 can be actually configured for. Fixes: 78a21c7d ("arm64: dts: rockchip: Add initial support for Pine64 PinePhone Pro") Signed-off-by:

Currently, if a symbol "@" is attempted to be used with an event probe (eprobes), it will cause a NULL pointer dereference crash. Both kprobes and uprobes can reference data other than the main registers. Such as immediate address, symbols and the current task name. Have eprobes do the same thing. For "comm", if "comm" is used and the event being attached to does not have the "comm" field, then make it the "$comm" that kprobes has. This is consistent to the way histograms and filters work.

Currently when an event probe (eprobe) hooks to a string field, it does not display it as a string, but instead as a number. This makes the field rather useless. Handle the different kinds of strings, dynamic, static, relational/dynamic etc. Now when a string field is used, the ":string" type can be used to display it: echo "e:sw sched/sched_switch comm=$next_comm:string" > dynamic_events Link: https://lkml.kernel.org/r/20220820134400.959640191@goodmis.org Cc: stable@vger.kernel.org Cc: Ingo Molnar <mingo@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Tzvetomir Stoyanov <tz.stoyanov@gmail.com> Cc: Tom Zanussi <zanussi@kernel.org> Fixes: 7491e2c4 ("tracing: Add a probe that attaches to trace events") Acked-by:

The variable $comm is hard coded as a string, which is true for both kprobes and uprobes, but for event probes (eprobes) it is a field name. In most cases the "comm" field would be a string, but there's no guarantee of that fact. Do not assume that comm is a string. Not to mention, it currently forces comm fields to fault, as string processing for event probes is currently broken.

If in perf_trace_event_init(), the perf_trace_event_open() fails, then it will call perf_trace_event_unreg() which will not only unregister the perf trace event, but will also call the put() function of the tp_event. The problem here is that the trace_event_try_get_ref() is called by the caller of perf_trace_event_init() and if perf_trace_event_init() returns a failure, it will then call trace_event_put(). But since the perf_trace_event_unreg() already called the trace_event_put() function, it triggers a WARN_ON(). WARNING: CPU: 1 PID: 30309 at kernel/trace/trace_dynevent.c:46 trace_event_dyn_put_ref+0x15/0x20 If perf_trace_event_reg() does not call the trace_event_try_get_ref() then the perf_trace_event_unreg() should not be calling trace_event_put(). This breaks symmetry and causes bugs like these. Pull out the trace_event_put() from perf_trace_event_unreg() and call it in the locations that perf_trace_event_unreg() is called. This not only fixes this bug, but also brings back the proper symmetry of the reg/unreg vs get/put logic.

The function traceprobe_parse_event_name() may set the first two function arguments to a non-null value and still return -EINVAL to indicate an unsuccessful completion of the function. Hence, it is not sufficient to just check the result of the two function arguments for being not null, but the return value also needs to be checked. Commit 95c104c3 ("tracing: Auto generate event name when creating a group of events") changed the error-return-value checking of the second traceprobe_parse_event_name() invocation in __trace_eprobe_create() and removed checking the return value to jump to the error handling case. Reinstate using the return value in the error-return-value checking.

GCC has supported asm goto since 4.5, and Clang has since version 9.0.0. The minimum supported versions of these tools for the build according to Documentation/process/changes.rst are 5.1 and 11.0.0 respectively. Remove the feature detection script, Kconfig option, and clean up some fallback code that is no longer supported. The removed script was also testing for a GCC specific bug that was fixed in the 4.7 release. Also remove workarounds for bpftrace using clang older than 9.0.0, since other BPF backend fixes are required at this point.

If for whatever reasons pm_runtime_resume_and_get() fails and .remove() is exited early, the i2c adapter stays around and the irq still calls its handler, while the driver data and the register mapping go away. So if later the i2c adapter is accessed or the irq triggers this results in havoc accessing freed memory and unmapped registers. So unregister the software resources even if resume failed, and only skip the hardware access in that case.

This `clang-analyzer` check flags the use of memset(), suggesting a more secure version of the API, such as memset_s(), which does not exist in the kernel: warning: Call to function 'memset' is insecure as it does not provide security checks introduced in the C11 standard. Replace with analogous functions that support length arguments or provides boundary checks such as 'memset_s' in case of C11 [clang-analyzer-security.insecureAPI.DeprecatedOrUnsafeBufferHandling] Signed-off-by:
