commit ce7eebe5c3deef8e19c177c24ee75843256e69ca upstream.
The compilation only looks for linux/magic.h from the default include
paths, which does not include the source tree. This results in a build
error if linux/magic.h is not available or not installed.For example, this build error occurs on CentOS 5.

Fixing the dynamic array format field parsing.
Currently the event_read_fields function could segfault while parsing
dynamic array other than string type. The reason is the event->pevent
does not need to be set and gets dereferenced unconditionaly.Also adding proper initialization of field->elementsize based on the
parsed dynamic type.Signed-off-by: Jiri Olsa

For some reason the libtraceevent tracepoint-parsing code is missing
the FIELD_IS_SIGNED flag-setting code, which causes problems for the
Perl trace event binding at least, since it ends up unable to
recognize negative numbers.Things like checking for negative return values therefore fail, causing
scripts like rwtop to instead interpret the negative return value as a
large positive value, which in turn get added to e.g. read totals with
insanely invalid results.So set the FIELD_IS_SIGNED flag for tracepoint events that specify
"signed:1".Before:

Ingo reported (again!) that 'make clean' on perf/traceevent does not

fixed in commit 860df5833e46 is back:make[1]: *** No rule to make target
`/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'. Stop.'make clean' itself does not work in libtraceevent:

make: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'. Stop.So I had to clean it out manually:
comet:~/tip/tools/lib/traceevent> git ls-files --others | xargs rm
comet:~/tip/tools/lib/traceevent>and then things build fine."
Try to fix it by excluding system headers from dependency generation.

Even though with the change of commit commit 2b29175 "tools lib
traceevent: Carve out events format parsing routine", allowed
__pevent_parse_format() to parse an event without the need of a pevent
handler, the event still needs to assign the pevent handed to it.There's no problem with assigning it if the pevent is NULL, as the
event->pevent would be NULL without the assignment. But function parsing
handlers may be assigned to the pevent handler to help in parsing the
event. If there's no pevent then there would not be any function
handlers, but if the pevent isn't assigned first before parsing the
event, it wont honor the function handlers that were assigned.Worse yet, the current code crashes if an event has a function that it
tries to parse. For example:# perf record -e scsi:scsi_dispatch_cmd_timeout
Segmentation fault (core dumped)This happens because the scsi_dispatch_cmd_timeout event format has the following:
scsi_trace_parse_cdb(p, __get_dynamic_array(cmnd), REC->cmd_len)
which hasn't been defined by the pevent code.

perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.Signed-off-by: Irina Tirdea

glibc-2.16 starts to mark the function with attribute warn_unused_result
so that it can cause a build warning.Since GNU version of strerror_r() can return a pointer to a string
without setting @buf, check the return value and copy/truncate it to our
buffer if needed.Signed-off-by: Namhyung Kim

The pevent_strerror() sets @buf to a string that describes the
(libtraceevent-specific) error condition that is passed via @errnum.This is similar to strerror_r() and does same thing if @errnum has a
standard errno value.To sync error string with its code, define PEVENT_ERRORS with _PE()
macro and use it as suggested by Steven.Signed-off-by: Namhyung Kim
