| | * | | tracing: Move mutex to protect against resetting of seq dataSteven Rostedt (Red Hat)2016-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 1245800c0f96eb6ebb368593e251d66c01e61022 upstream. The iter->seq can be reset outside the protection of the mutex. So can reading of user data. Move the mutex up to the beginning of the function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | saved_tgids is fixed size array but uses index upto savedcmd->cmdline_num. savedcmd->cmdline_num can change with modification to saved_cmdlines_size node. Fix this indexing by making saved_tgid part of savedcmd and modify it's size with changes to saved_cmdline_size.

* | | | tracing: Use SOFTIRQ_OFFSET for softirq dectection for more accurate resultsPavankumar Kondeti2017-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 's' flag is supposed to indicate that a softirq is running. This can be detected by testing the preempt_count with SOFTIRQ_OFFSET. The current code tests the preempt_count with SOFTIRQ_MASK, which would be true even when softirqs are disabled but not serving a softirq.

| * | | tracing: Fix crash from reading trace_pipe with sendfileSteven Rostedt (Red Hat)2016-04-12
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a29054d9478d0435ab01b7544da4f674ab13f533 upstream. If tracing contains data and the trace_pipe file is read with sendfile(), then it can trigger a NULL pointer dereference and various BUG_ON within the VM code. There's a patch to fix this in the splice_to_pipe() code, but it's also a good idea to not let that happen from trace_pipe either.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function trace_printk() performs optimization by determining if there are no format parameters in argument string and calls appropriate apis to write to ftrace buffer. Add STM logging to support this optimization in order to allow CoreSight STM tracing for optimized trace_printk path.

| * tracing: Fix stacktrace skip depth in trace_buffer_unlock_commit_regs()Steven Rostedt (Red Hat)2016-02-17

But return -ENODEV if debugfs is configured in but not initialized or failed to create automount point as that would break backward compatibility with older tools.

* tracing: Put back comma for empty fields in boot string parsingSteven Rostedt (Red Hat)2015-11-03
| | | | | | | | | | | | | | | | | | Both early_enable_events() and apply_trace_boot_options() parse a boot string that may get parsed later on. They both use strsep() which converts a comma into a nul character. To still allow the boot string to be parsed again the same way, the nul character gets converted back to a comma after the token is processed. The problem is that these two functions check for an empty parameter (two commas in a row ",,"), and continue the loop if the parameter is empty, but fails to place the comma back. In this case, the second parsing will end at this blank field, and not process fields afterward. In most cases, users should not have an empty field, but if its going to be checked, the code might as well be correct. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* tracing: Apply tracer specific options from kernel command line.Jiaxing Wang2015-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the trace_options parameter is only applied in tracer_alloc_buffers() when global_trace.current_trace is nop_trace, so a tracer specific option will not be applied even when the specific tracer is also enabled from kernel command line. For example, the 'func_stack_trace' option can't be enabled with the following kernel parameter: ftrace=function ftrace_filter=kfree trace_options=func_stack_trace We can enable tracer specific options by simply apply the options again if the specific tracer is also supplied from command line and started in register_tracer(). To make trace_boot_options_buf can be parsed again, a comma and a space is put back if they were replaced by strsep and strstrip respectively. Also make register_tracer() be __init to access the __init data, and in fact register_tracer is only called from __init code.

A new field is added to the trace_array descriptor called trace_flags_index, which is a 32 byte character array representing a bit. This array is simply filled with the index of the array, where index_array[n] = n; Then the address of this array is passed to the file callbacks instead of the index of the flag index. Then to retrieve both the flag index and the trace_array descriptor: data is the passed in argument. index = *(unsigned char *)data; data -= index; /* Now data points to the address of the array in the trace_array */ tr = container_of(data, struct trace_array, trace_flags_index); Suggested-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| | | | | | | | | | | | | | | | | In preparation to make trace options per instance, the global trace_flags needs to be moved from being a global variable to a field within the trace instance trace_array structure. There's still more work to do, as there's some functions that use trace_flags without passing in a way to get to the current_trace array. For those, the global_trace is used directly (from trace.c). This includes setting and clearing the trace_flags. This means that when a new instance is created, it just gets the trace_flags of the global_trace and will not be able to modify them. Depending on the functions that have access to the trace_array, the flags of an instance may not affect parts of its trace, where the global_trace is used. These will be fixed in future changes.

* tracing: Always show all tracer options in the options directorySteven Rostedt (Red Hat)2015-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are options that are unique to a specific tracer (like function and function graph). Currently, these options are only visible in the options directory when the tracer is enabled. This has been a pain, especially for something like the func_stack_trace option that if used inappropriately, could bring the system to a crawl. But the only way to see it, is to enable the function tracer. For example, if one had done: # cd /sys/kernel/tracing # echo __schedule > set_ftrace_filter # echo 1 > options/func_stack_trace # echo function > current_tracer The __schedule call will be traced and a stack trace will also be recorded there. Now when you were done, you may do... # echo nop > current_tracer # echo > set_ftrace_filter But you forgot to disable the func_stack_trace. The only way to disable it is to re-enable function tracing first. If you do not add a filter to set_ftrace_filter and just do: # echo function > current_tracer Now you would be performing a stack trace on *every* function! On some systems, that causes a live lock. Others may take a few minutes to fix your mistake. Having the func_stack_trace option visible allows you to check it and disable it before enabling the funtion tracer.

The macro TRACE_FLAGS is defined as a serious of enum names followed by the string name of the file that matches it. For example: #define TRACE_FLAGS \ C(PRINT_PARENT, "print-parent"), \ C(SYM_OFFSET, "sym-offset"), \ C(SYM_ADDR, "sym-addr"), \ C(VERBOSE, "verbose"), Now we can define the following: #undef C #define C(a, b) TRACE_ITER_##a##_BIT enum trace_iterator_bits { TRACE_FLAGS }; The above creates: enum trace_iterator_bits { TRACE_ITER_PRINT_PARENT_BIT, TRACE_ITER_SYM_OFFSET_BIT, TRACE_ITER_SYM_ADDR_BIT, TRACE_ITER_VERBOSE_BIT, }; Then we can redefine C as: #undef C #define C(a, b) TRACE_ITER_##a = (1 << TRACE_ITER_##a##_BIT) enum trace_iterator_flags { TRACE_FLAGS }; Which creates: enum trace_iterator_flags { TRACE_ITER_PRINT_PARENT = (1 << TRACE_ITER_PRINT_PARENT_BIT), TRACE_ITER_SYM_OFFSET = (1 << TRACE_ITER_SYM_OFFSET_BIT), TRACE_ITER_SYM_ADDR = (1 << TRACE_ITER_SYM_ADDR_BIT), TRACE_ITER_VERBOSE = (1 << TRACE_ITER_VERBOSE_BIT), }; Then finally we can create the list of file names: #undef C #define C(a, b) b static const char *trace_options[] = { TRACE_FLAGS NULL }; Which creates: static const char *trace_options[] = { "print-parent", "sym-offset", "sym-addr", "verbose", NULL }; The importance of this is that the strings match the bit index. trace_options[TRACE_ITER_SYM_ADDR_BIT] == "sym-addr" Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* ftrace: Provide trace clock monotonic rawDrew Richardson2015-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expose the NMI safe accessor to the monotonic raw clock to the tracer. The mono clock was added with commit 1b3e5c0936046e7e023149ddc8946d21c2ea20eb. The advantage of the monotonic raw clock is that it will advance more constantly than the monotonic clock. Imagine someone is trying to optimize a particular program to reduce instructions executed for a given workload while minimizing the effect on runtime. Also suppose that NTP is running and potentially making larger adjustments to the monotonic clock. If NTP is adjusting the monotonic clock to advance more rapidly, the program will appear to use fewer instructions per second but run longer than if the monotonic raw clock had been used. The total number of instructions observed would be the same regardless of the clock source used, but how it's attributed to time would be affected. Conversely if NTP is adjusting the monotonic clock to advance more slowly, the program will appear to use more instructions per second but run more quickly. Of course there are many sources that can cause jitter in performance measurements on modern processors, but let's remove NTP from the list. The monotonic raw clock can also be useful for tracing early boot, e.g. when debugging issues with NTP.
