perf intel-pt: Fix potential NULL pointer dereference found by the smatch tool (2019-07-09 10:13:28 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Intel PT:
Adrian Hunter:
- Fix DROP VIEW power_events_view in the postgresql and sqlite export-db
python scripts.
perf script:
Song Liu:
- Assume native_arch for pipe mode, fixing a segfault.
perf inject:
Arnaldo Carvalho de Melo:
- The tool->read() call may pass a NULL evsel, handle it.
core:
Arnaldo Carvalho de Melo:
- Move zalloc/zfree.c to tools/lib, further eroding tools/perf/util.[ch]
- Use zfree() where applicable instead of open coded equivalent.
- Add stdlib.h and some other headers to places where its needed and were
getting via util.h, that doesn't need that anymore.
- Use list_del_init() more thoroughly.
Miscellaneous:
Leo Yan:
- Fix use after free and potential NULL pointer derefs detected by the
smatch tool in various places.
Luke Mujica:
- Remove a couple unused variables in the parse-events code.
Numfor Mbiziwo-Tiapo:
- Initialize variable to suppress memory sanitizer warning in the
mmap-thread-lookup 'perf test' entry.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

From: Numfor Mbiziwo-Tiapo <nums@google.com>
Running the 'perf test' command after building perf with a memory
sanitizer causes a warning that says:
WARNING: MemorySanitizer: use-of-uninitialized-value... in mmap-thread-lookup.c
Initializing the go variable to 0 silences this harmless warning.
Committer warning:
This was harmless, just a simple test writing whatever was at that
sizeof(int) memory area just to signal another thread blocked reading
that file created with pipe(). Initialize it tho so that we don't get
this warning.

Based on the following report from Smatch, fix the use-after-freed
pointer.
tools/perf/builtin-stat.c:1353
add_default_attributes() warn: passing freed memory 'str'.
The pointer 'str' has been freed but later it is still passed into the
function parse_events_print_error(). This patch fixes this
use-after-freed issue.

Based on the following report from Smatch, fix the potential
dereferencing freed memory check.
tools/perf/util/annotate.c:1125
disasm_line__parse() error: dereferencing freed memory 'namep'
tools/perf/util/annotate.c
1100 static int disasm_line__parse(char *line, const char **namep, char **rawp)
1101 {
1102 char tmp, *name = ltrim(line);
[...]
1114 *namep = strdup(name);
1115
1116 if (*namep == NULL)
1117 goto out_free_name;
[...]
1124 out_free_name:
1125 free((void *)namep);
^^^^^
1126 *namep = NULL;
^^^^^^
1127 return -1;
1128 }
If strdup() fails to allocate memory space for *namep, we don't need to
free memory with pointer 'namep', which is resident in data structure
disasm_line::ins::name; and *namep is NULL pointer for this failure, so
it's pointless to assign NULL to *namep again.
Committer note:
Freeing namep, which is the address of the first entry of the 'struct
ins' that is the first member of struct disasm_line would in fact free
that disasm_line instance, if it was allocated via malloc/calloc, which,
later, would a dereference of freed memory.

Check first, as machines__deliver_event() may have
perf_evlist__id2evsel() returning NULL.
This was found while checking a report from Leo Yan that used the smatch
tool to find places where a pointer is checked before use and then,
later in the same function gets used without checking.

Based on the following report from Smatch, fix the potential
NULL pointer dereference check.
tools/perf/util/session.c:1252
dump_read() error: we previously assumed 'evsel' could be null
(see line 1249)
tools/perf/util/session.c
1240 static void dump_read(struct perf_evsel *evsel, union perf_event *event)
1241 {
1242 struct read_event *read_event = &event->read;
1243 u64 read_format;
1244
1245 if (!dump_trace)
1246 return;
1247
1248 printf(": %d %d %s %" PRIu64 "\n", event->read.pid, event->read.tid,
1249 evsel ? perf_evsel__name(evsel) : "FAIL",
1250 event->read.value);
1251
1252 read_format = evsel->attr.read_format;
^^^^^^^
'evsel' could be NULL pointer, for this case this patch directly bails
out without dumping read_event.

we need to add it to places where it is needed but was getting it

From: Arnaldo Carvalho de Melo <acme@redhat.com>
In places where the equivalent was already being done, i.e.:
free(a);
a = NULL;
And in placs where struct members are being freed so that if we have
some erroneous reference to its struct, then accesses to freed members
will result in segfaults, which we can detect faster than use after free
to areas that may still have something seemingly valid.

Based on the following report from Smatch, fix the potential NULL
pointer dereference check.
tools/perf/util/cs-etm.c:2545
cs_etm__process_auxtrace_info() error: we previously assumed
'session->itrace_synth_opts' could be null (see line 2541)

2541 if (session->itrace_synth_opts && session->itrace_synth_opts->set) {
2542 etm->synth_opts = *session->itrace_synth_opts;
2543 } else {
2544 itrace_synth_opts__set_default(&etm->synth_opts,
2545 session->itrace_synth_opts->default_no_sample);
^^^^^^^^^^^^^^^^^^^^^^^^^^
2546 etm->synth_opts.callchain = false;
2547 }
'session->itrace_synth_opts' is impossible to be a NULL pointer in
cs_etm__process_auxtrace_info(), thus this patch removes the NULL
test for 'session->itrace_synth_opts'.

This patch firstly validating the pointers before access them, so can
fix potential NULL pointer dereference.

Drop power_events_view before its dependent tables.
SQLite does not seem to mind but the fix was needed for PostgreSQL
(export-to-postgresql.py script), so do the same fix for the SQLite. It is
more logical and keeps the 2 scripts following the same approach.

From: Song Liu <songliubraving@fb.com>
In pipe mode, session->header.env.arch is not populated until the events
are processed. Therefore, the following command crashes:
perf record -o - | perf script
(gdb) bt
It fails when we try to compare env.arch against uts.machine:
if (!strcmp(uts.machine, session->header.env.arch) ||
(!strcmp(uts.machine, "x86_64") &&
!strcmp(session->header.env.arch, "i386")))
native_arch = true;
In pipe mode, it is tricky to find env.arch at this stage. To keep it
simple, let's just assume native_arch is always true for pipe mode.

Based on the following report from Smatch, fix the potential NULL
pointer dereference check.
tools/perf/util/intel-bts.c:898
intel_bts_process_auxtrace_info() error: we previously assumed
'session->itrace_synth_opts' could be null (see line 894)

895 bts->synth_opts = *session->itrace_synth_opts;
896 } else {
897 itrace_synth_opts__set_default(&bts->synth_opts,
898 session->itrace_synth_opts->default_no_sample);
^^^^^^^^^^^^^^^^^^^^^^^^^^
899 if (session->itrace_synth_opts)
^^^^^^^^^^^^^^^^^^^^^^^^^^
900 bts->synth_opts.thread_stack =
901 session->itrace_synth_opts->thread_stack;
902 }
'session->itrace_synth_opts' is impossible to be a NULL pointer in
intel_bts_process_auxtrace_info(), thus this patch removes the NULL test
for 'session->itrace_synth_opts'.
