The traceevent lib is used by the perf tool, and when executing
perf test -v 6
it outputs error log on the ARM64 platform:
running test 33 '*:*'trace-cmd: No such file or directory
[...]
trace-cmd: Invalid argument
The trace event parsing code originally came from trace-cmd so it keeps
the tag string "trace-cmd" for errors, this easily introduces the
impression that the perf tool launches trace-cmd command for trace event
parsing, but in fact the related parsing is accomplished by the
traceevent lib.
This patch changes the tag string to "libtraceevent" so that we can
avoid confusion and let users to more easily connect the error with
traceevent lib.

There was a missing comparison with 0 when checking if type is "s64" or
"u64". Therefore, the body of the if-statement was entered if "type" was
"u64" or not "s64", which made the first strcmp() redundant since if
type is "u64", it's not "s64".
If type is "s64", the body of the if-statement is not entered but since
the remainder of the function consists of if-statements which will not
be entered if type is "s64", we will just return "val", which is
correct, albeit at the cost of a few more calls to strcmp(), i.e., it
will behave just as if the if-statement was entered.
If type is neither "s64" or "u64", the body of the if-statement will be
entered incorrectly and "val" returned. This means that any type that is
checked after "s64" and "u64" is handled the same way as "s64" and
"u64", i.e., the limiting of "val" to fit in for example "s8" is never
reached.
This was introduced in the kernel tree when the sources were copied from
trace-cmd in commit f7d82350e597 ("tools/events: Add files to create
libtraceevent.a"), and in the trace-cmd repo in 1cdbae6035cei
("Implement typecasting in parser") when the function was introduced,
i.e., it has always behaved the wrong way.
Detected by cppcheck.

Fix buffer overflow observed when running perf test.
The overflow is when trying to evaluate "1ULL << (64 - 1)" which is
resulting in -9223372036854775808 which overflows the 20 character
buffer.
If is possible this bug has been reported before but I still don't see
any fix checked in:

In order to make libtraceevent into a proper library, its API
should be straightforward.
After discussion with Steven Rostedt, we decided to remove the
tep_data_event_from_type() API and to replace it with tep_find_event(),
as it does the same.

In order to make libtraceevent into a proper library, its API
should be straightforward.
The tep_register_event_handler() functions returns -1 in case it
successfully registers the new event handler. Such return code is used
by the other library APIs in case of an error.
To unify the return logic of tep_register_event_handler() with the other
APIs, this patch introduces enum tep_reg_handler, which is used by this
function as return value, to handle all possible successful return
cases.

trace_seq_vprintf() APIs
In order to make libtraceevent into a proper library, its API should be
straightforward.
The trace_seq_printf() and trace_seq_vprintf() APIs have inconsistent
returned values with the other trace_seq_* APIs.
This path changes the return logic of trace_seq_printf() and
trace_seq_vprintf() to return the number of printed characters, as the
other trace_seq_* related APIs.

No change in functionality intended.
Committer notes:
This was split from a larger patch as there are code that is,
additionally, maintained outside the kernel tree, so to ease cherry

tep_free_event(), tep_free_format_field(), __tep_data2host2(),

This patch implements a new API of the tracevent library:
int tep_get_ref(struct tep_handle *tep);
The API returns the reference counter "ref_count" of the tep handler.
As "struct tep_handle" is internal only, its members cannot be accessed
by the library users, the API is used to get the reference counter.

local header file
As traceevent is going to be transferred into a proper library,
its local data should be protected from the library users.
This patch encapsulates struct tep_handler into a local header,
not visible outside of the library. It implements also a bunch
of new APIs, which library users can use to access tep_handler members.

While working on having PowerTop use libtracevent as a shared object
library, Tzvetomir hit "str_error_r not defined". This was added by commit
c3cec9e68f12d ("tools lib traceevent: Use str_error_r()") because
strerror_r() has two definitions, where one is GNU specific, and the other
is XSI complient. The strerror_r() is in a wrapper str_error_r() to keep the
code from having to worry about which compiler is being used.
The problem is that str_error_r() is external to libtraceevent, and not part
of the library. If it is used as a shared object then the tools using it
will need to define that function. I do not want that function defined in
libtraceevent itself, as it is out of scope for that library.
As there's only a single instance of this call, and its in the traceevent
library's own tep_strerror() function, we can copy what was done in perf,
and create yet another external file that undefs _GNU_SOURCE to use the more
portable version of the function. We don't need to worry about the errors
that strerror_r() returns. If the buffer isn't big enough, we simply
truncate it.

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_". This adds prefix tep_ to enums
filter_exp_type, filter_arg_type and all enum's members
