de04f8657d tools lib traceevent: Fix memory leak in pretty_print()
Commit 12e55569a2 "tools lib traceevent: Use helper trace-seq in print
functions like kernel does" added a extra trace_seq helper to process
string arguments like the kernel does it. But the difference between the
kernel and the userspace library is that the kernel's trace_seq structure
has a static allocated buffer. The userspace one has a dynamically
allocated one. It requires a trace_seq_destroy(), otherwise it produces
a nasty memory leak.

4508793541 tools lib traceevent: Fix backward compatibility macros for pevent filter enums
The return value for pevent_filter_match() is suppose to return FILTER_NONE
if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter
at all. But the change 41e12e580a "tools lib traceevent: Refactor
pevent_filter_match() to get rid of die()" replaced the return value
with PEVENT_ERRNO__* values and added "backward compatibility" macros
that used the old names. Unfortunately, the NOEXIST and NONE macros were
swapped, and this broke users that use the old return names.

9e9e5dfd86 tools lib traceevent: Do not call warning() directly
The patch 3a3ffa2e82 ("tools lib traceevent: Report better error
message on bad function args") added the error message but it seems
there's no reason to call warning() directly.

So change it to do_warning_event() to provide event information too.

b935a58dbf perf tools: Fix traceevent plugin path definitions
The plugindir_SQ definition contains $(prefix) which is not needed as
the $(libdir) definition already contains prefix in it.  This leads to
the path including an extra prefix in it, e.g. /usr/usr/lib64.

The -DPLUGIN_DIR defintion includes DESTDIR.  This is incorrect, as it
sets the plugin search path to include the value of DESTDIR.  DESTDIR is
a mechanism to install in a non-standard location such as a chroot or an
RPM build root.  In the RPM case, this leads to the search path being
incorrect after the resulting RPM is installed (or in some cases an RPM
build failure).

Remove both of these unnecessary inclusions.

9326657abe Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
 "Kernel side changes:

   - Add Intel RAPL energy counter support (Stephane Eranian)
   - Clean up uprobes (Oleg Nesterov)
   - Optimize ring-buffer writes (Peter Zijlstra)

  Tooling side changes, user visible:

   - 'perf diff':
     - Add column colouring improvements (Ramkumar Ramachandra)

  - 'perf kvm':
     - Add guest related improvements, including allowing to specify a
       directory with guest specific /proc information (Dongsheng Yang)
     - Add shell completion support (Ramkumar Ramachandra)
     - Add '-v' option (Dongsheng Yang)
     - Support --guestmount (Dongsheng Yang)

   - 'perf probe':
     - Support showing source code, asking for variables to be collected
       at probe time and other 'perf probe' operations that use DWARF
       information.

       This supports only binaries with debugging information at this
       time, detached debuginfo (aka debuginfo packages) support should
       come in later patches (Masami Hiramatsu)

   - 'perf record':
     - Rename --no-delay option to --no-buffering, better reflecting its
       purpose and freeing up '--delay' to take the place of
       '--initial-delay', so that 'record' and 'stat' are consistent
       (Arnaldo Carvalho de Melo)
     - Default the -t/--thread option to no inheritance (Adrian Hunter)
     - Make per-cpu mmaps the default (Adrian Hunter)

   - 'perf report':
     - Improve callchain processing performance (Frederic Weisbecker)
     - Retain bfd reference to lookup source line numbers, greatly
       optimizing, among other use cases, 'perf report -s srcline'
       (Adrian Hunter)
     - Improve callchain processing performance even more (Namhyung Kim)
     - Add a perf.data file header window in the 'perf report' TUI,
       associated with the 'i' hotkey, providing a counterpart to the
       --header option in the stdio UI (Namhyung Kim)

   - 'perf script':
     - Add an option in 'perf script' to print the source line number
       (Adrian Hunter)
     - Add --header/--header-only options to 'script' and 'report', the
       default is not tho show the header info, but as this has been the
       default for some time, leave a single line explaining how to
       obtain that information (Jiri Olsa)
     - Add options to show comm, fork, exit and mmap PERF_RECORD_ events
       (Namhyung Kim)
     - Print callchains and symbols if they exist (David Ahern)

   - 'perf timechart'
     - Add backtrace support to CPU info
     - Print pid along the name
     - Add support for CPU topology
     - Add new option --highlight'ing threads, be it by name or, if a
       numeric value is provided, that run more than given duration
       (Stanislav Fomichev)

   - 'perf top':
     - Make 'perf top -g' refer to callchains, for consistency with
       other tools (David Ahern)

   - 'perf trace':
     - Handle old kernels where the "raw_syscalls" tracepoints were
       called plain "syscalls" (David Ahern)
     - Remove thread summary coloring, by Pekka Enberg.
     - Honour -m option in 'trace', the tool was offering the option to
       set the mmap size, but wasn't using it when doing the actual mmap
       on the events file descriptors (Jiri Olsa)

   - generic:
     - Backport libtraceevent plugin support (trace-cmd repository, with
       plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,
       function, xen, scsi, cfg80211 (Jiri Olsa)
     - Print session information only if --stdio is given (Namhyung Kim)

  Tooling side changes, developer visible (plumbing):

   - Improve 'perf probe' exit path, release resources (Masami
     Hiramatsu)
   - Improve libtraceevent plugins exit path, allowing the registering
     of an unregister handler to be called at exit time (Namhyung Kim)
   - Add an alias to the build test makefile (make -C tools/perf
     build-test) (Namhyung Kim)
   - Get rid of die() and friends (good riddance!) in libtraceevent
     (Namhyung Kim)
   - Fix cross build problems related to pkgconfig and CROSS_COMPILE not
     being propagated to the feature tests, leading to features being
     tested in the host and then being enabled on the target (Mark
     Rutland)
   - Improve forked workload error reporting by sending the errno in the
     signal data queueing integer field, using sigqueue and by doing the
     signal setup in the evlist methods, removing open coded equivalents
     in various tools (Arnaldo Carvalho de Melo)
   - Do more auto exit cleanup chores in the 'evlist' destructor, so
     that the tools don't have to all do that sequence (Arnaldo Carvalho
     de Melo)
   - Pack 'struct perf_session_env' and 'struct trace' (Arnaldo Carvalho
     de Melo)
   - Add test for building detached source tarballs (Arnaldo Carvalho de
     Melo)
   - Move some header files (tools/perf/ to tools/include/ to make them
     available to other tools/ dwelling codebases (Namhyung Kim)
   - Move logic to warn about kptr_restrict'ed kernels to separate
     function in 'report' (Arnaldo Carvalho de Melo)
   - Move hist browser selection code to separate function (Arnaldo
     Carvalho de Melo)
   - Move histogram entries collapsing to separate function (Arnaldo
     Carvalho de Melo)
   - Introduce evlist__for_each() & friends (Arnaldo Carvalho de Melo)
   - Automate setup of FEATURE_CHECK_(C|LD)FLAGS-all variables (Jiri
     Olsa)
   - Move arch setup into seprate Makefile (Jiri Olsa)
   - Make libtraceevent install target quieter (Jiri Olsa)
   - Make tests/make output more compact (Jiri Olsa)
   - Ignore generated files in feature-checks (Chunwei Chen)
   - Introduce pevent_filter_strerror() in libtraceevent, similar in
     purpose to libc's strerror() function (Namhyung Kim)
   - Use perf_data_file methods to write output file in 'record' and
     'inject' (Jiri Olsa)
   - Use pr_*() functions where applicable in 'report' (Namhyumg Kim)
   - Add 'machine' 'addr_location' struct to have full picture (machine,
     thread, map, symbol, addr) for a (partially) resolved address,
     reducing function signatures (Arnaldo Carvalho de Melo)
   - Reduce code duplication in the histogram entry creation/insertion
     (Arnaldo Carvalho de Melo)
   - Auto allocate annotation histogram data structures (Arnaldo
     Carvalho de Melo)
   - No need to test against NULL before calling free, also set freed
     memory in struct pointers to NULL, to help fixing use after free
     bugs (Arnaldo Carvalho de Melo)
   - Rename some struct DSO binary_type related members and methods, to
     clarify its purpose and need for differentiation (symtab_type, ie
     one is about the files .text, CFI, etc, i.e.  its binary contents,
     and the other is about where the symbol table came from (Arnaldo
     Carvalho de Melo)
   - Convert to new topic libraries, starting with an API one (sysfs,
     debugfs, etc), renaming liblk in the process (Borislav Petkov)
   - Get rid of some more panic() like error handling in libtraceevent.
     (Namhyung Kim)
   - Get rid of panic() like calls in libtraceevent (Namyung Kim)
   - Start carving out symbol parsing routines (perf, just moving
     routines to topic files in tools/lib/symbol/, tools that want to
     use it need to integrate it directly, ie no
     tools/lib/symbol/Makefile is provided (Arnaldo Carvalho de Melo)
   - Assorted refactoring patches, moving code around and adding utility
     evlist methods that will be used in the IPT patchset (Adrian
     Hunter)
   - Assorted mmap_pages handling fixes (Adrian Hunter)
   - Several man pages typo fixes (Dongsheng Yang)
   - Get rid of several die() calls in libtraceevent (Namhyung Kim)
   - Use basename() in a more robust way, to avoid problems related to
     different system library implementations for that function
     (Stephane Eranian)
   - Remove open coded management of short_name_allocated member (Adrian
     Hunter)
   - Several cleanups in the "dso" methods, constifying some parameters
     and renaming some fields to clarify its purpose (Arnaldo Carvalho
     de Melo)
   - Add per-feature check flags, fixing libunwind related build
     problems on some architectures (Jean Pihet)
   - Do not disable source line lookup just because of one failure.
     (Adrian Hunter)
   - Several 'perf kvm' man page corrections (Dongsheng Yang)
   - Correct the message in feature-libnuma checking, swowing the right
     devel package names for various distros (Dongsheng Yang)
   - Polish 'readn()' function and introduce its counterpart,
     'writen()' (Jiri Olsa)
   - Start moving timechart state from global variables to a 'perf_tool'
     derived 'timechart' struct (Arnaldo Carvalho de Melo)

0e9e79a13a tools lib traceevent: fix pointer-integer size mismatch
The scsi and cfg80211 plugins cast between unsigned long long and
pointers, which is problematic for architectures where unsigned long
long is wider than the native pointer size:

  linux/tools/lib/traceevent/plugin_scsi.c: In function ‘process_scsi_trace_parse_cdb’:
  linux/tools/lib/traceevent/plugin_scsi.c:408:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    scsi_trace_parse_cdb(s, (unsigned char *) args[1], args[2]);

  linux/tools/lib/traceevent/plugin_cfg80211.c: In function ‘process___le16_to_cpup’:
  linux/tools/lib/traceevent/plugin_cfg80211.c:11:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    uint16_t *val = (uint16_t *) args[0];

This patch adds an intermediate cast to unsigned long, silencing the
warning.

which triggers when traceevent library needs to be rebuilt, but we have

Adding extra 'plugins' target with nop which is visible and triggers in
both Makefile parts (for detached output directory (O=...) the
traceevent Makefile spawns sub make for the build itself).

bf19b82e7c tools lib traceevent: Introduce pevent_filter_strerror()
The pevent_filter_strerror() function is for receiving actual error
message from pevent_errno value.  To do that, add a static buffer to
event_filter for saving internal error message

If a failed function saved other information in the static buffer
returns the information, otherwise returns generic error message.

f23b24f1bf tools lib traceevent: Get rid of die() in some string conversion functions
Those functions stringify filter arguments.

As caller of those functions handles NULL string properly, it seems that
it's enough to return NULL rather than calling die().

553873e1df tools/: Convert to new topic libraries
Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.

For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.

acme:

"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.

But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

Fixup documentation cleaning target while at it.

41e12e580a tools lib traceevent: Refactor pevent_filter_match() to get rid of die()
The test_filter() function is for testing given filter is matched to a
given record.  However it doesn't handle error cases properly so add a
new argument err to save error info during the test and also pass it to
internal test functions.

The return value of pevent_filter_match() also converted to pevent_errno
to indicate an exact error case.
