perf tools: Cleanup trace-event-info 'tdata' leak

2018-11-21T08:27:31+00:00

[ Upstream commit faedbf3fd19f2511a39397f76359e4cc6ee93072 ]

Fixes the following coverity complaint:

  Error: RESOURCE_LEAK (CWE-772):
  leaked_storage: Variable "tdata" going out of scope leaks the storage

perf tools: Free temporary 'sys' string in read_event_files()

2018-11-21T08:27:31+00:00

[ Upstream commit 1e44224fb0528b4c0cc176bde2bb31e9127eb14b ]

For each system in a given pevent, read_event_files() reads in a
temporary 'sys' string.  Be sure to free this string before moving onto
to the next system and/or leaving read_event_files().

Fixes the following coverity complaints:

  Error: RESOURCE_LEAK (CWE-772):

  tools/perf/util/trace-event-read.c:343: overwrite_var: Overwriting
  "sys" in "sys = read_string()" leaks the storage that "sys" points to.

  tools/perf/util/trace-event-read.c:353: leaked_storage: Variable "sys"
  going out of scope leaks the storage it points to.

perf tools: Disable parallelism for 'make clean'

2018-11-10T15:41:41+00:00

[ Upstream commit da15fc2fa9c07b23db8f5e479bd8a9f0d741ca07 ]

The Yocto build system does a 'make clean' when rebuilding due to
changed dependencies, and that consistently fails for me (causing the
whole BSP build to fail) with errors such as

| find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory
| find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory
| find: find: '[...]/perf/1.0-r9/perf-1.0/libtraceevent.a''[...]/perf/1.0-r9/perf-1.0/libtraceevent.a': No such file or directory: No such file or directory
|
[...]
| find: cannot delete '/mnt/xfs/devel/pil/yocto/tmp-glibc/work/wandboard-oe-linux-gnueabi/perf/1.0-r9/perf-1.0/util/.pstack.o.cmd': No such file or directory

Apparently (despite the comment), 'make clean' ends up launching
multiple sub-makes that all want to remove the same things - perhaps
this only happens in combination with a O=... parameter. In any case, we
don't lose much by explicitly disabling the parallelism for the clean
target, and it makes automated builds much more reliable.

perf script python: Fix export-to-postgresql.py occasional failure

commit 25e11700b54c7b6b5ebfc4361981dae12299557b upstream.

Occasional export failures were found to be caused by truncating 64-bit
pointers to 32-bits. Fix by explicitly setting types for all ctype
arguments and results.

tools/vm/slabinfo.c: fix sign-compare warning

[ Upstream commit 904506562e0856f2535d876407d087c9459d345b ]

Currently we get the following compiler warning:

    slabinfo.c:854:22: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
       if (s->object_size < min_objsize)
                          ^

due to the mismatch of signed/unsigned comparison.  ->object_size and
->slab_size are never expected to be negative, so let's define them as
unsigned int.

selftest: timers: Tweak raw_skew to SKIP when ADJ_OFFSET/other clock adjustments are in progress

2018-09-26T06:35:09+00:00

[ Upstream commit 1416270f4a1ae83ea84156ceba19a66a8f88be1f ]

In the past we've warned when ADJ_OFFSET was in progress, usually
caused by ntpd or some other time adjusting daemon running in non
steady sate, which can cause the skew calculations to be
incorrect.

Thus, this patch checks to see if the clock was being adjusted
when we fail so that we don't cause false negatives.
