Subject: [PATCH] tools lib traceevent: Fix missing equality check for strcmp
|
||||
|
||||
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.

Subject: [PATCH] trace-cmd: Add option to poll trace buffers
|
||||
|
||||
Waiting for data to be available on the trace ring-buffers may trigger
|
||||
IPIs. This might generate unacceptable trace noise when debugging low
|
||||
latency or real time systems. So introduce the poll option. When
|
||||
enabled, it forces trace-cmd to use O_NONBLOCK. The drawback to using it
|
||||
is that traces will be extracted by busy waiting, which will
|
||||
unnecessarily hog the CPUs, so only use when really needed.

Subject: [PATCH 1/2] trace-cmd: Optimize how pid filters are expressed
|
||||
|
||||
Express pid filters as allowed/disallowed filter ranges
|
||||
|
||||
(pid>=100&&pid<=103)
|
||||
|
||||
instead of specifying them per pid
|
||||
|
||||
(pid==100||pid==101||pid==102||pid==103)
|
||||
|
||||
This makes the size of the resulting filter smaller (and faster) and avoids
|
||||
overflowing the filter size limit of one page which we can hit on bigger
|
||||
machines (say >160 CPUs).
