[PATCH v3 1/7] tracing: Don't show dynamic string internals in synthetic event description

2020-10-13 Thread Tom Zanussi
For synthetic event dynamic fields, the type contains "__data_loc", which is basically an internal part of the type which is only meant to be displayed in the format, not in the event description itself, which is confusing to users since they can't use __data_loc on the command-line to define an ev

[PATCH v3 3/7] tracing: Check that the synthetic event and field names are legal

2020-10-13 Thread Tom Zanussi
Call the is_good_name() function used by probe events to make sure synthetic event and field names don't contain illegal characters and cause unexpected parsing of synthetic event commands. Fixes: 4b147936fa50 (tracing: Add support for 'synthetic' events) Reported-by: Masami Hiramatsu Reviewed-by

This test uses waking+wakeup_latency as an event name, which doesn't make sense since it includes an operator. Illegal names are now detected by the synthetic event command parsing, which causes this test to fail. Change the name to 'waking_plus_wakeup_latency' to prevent this. Fixes: f06eec4d0f
