perf bpf: Return NULL when RB tree lookup fails in perf_env__find_btf() (2019-04-17 14:30:23 -0300)
---------------------------------------------------------------- perf/urgent fixes:
perf top:
Jiri Olsa:
- Fix 'perf top --pid', it needs PERF_SAMPLE_TIME since we switched to using a different thread to sort the events and then even for just a single thread we now need timestamps.
BPF:
Jiri Olsa:
- Fix bpf_prog and btf lookup functions failure path to to properly return NULL.
- Fix side band thread draining, used to process PERF_RECORD_BPF_EVENT metadata records.
core:
Jiri Olsa:
- Fix map lookup by name to get a refcount when the name is already in the tree. Found
Song Liu:
- Fix __map__is_kmodule() by taking into account recently added BPF maps.
UAPI:
Arnaldo Carvalho de Melo:
- Sync sound/asound.h copy
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
---------------------------------------------------------------- Arnaldo Carvalho de Melo (1): tools include uapi: Sync sound/asound.h copy
Jiri Olsa (5): perf top: Always sample time to satisfy needs of use of ordered queuing perf bpf: Return NULL when RB tree lookup fails in perf_env__find_bpf_prog_info() perf evlist: Fix side band thread draining perf tools: Fix map reference counting perf bpf: Return NULL when RB tree lookup fails in perf_env__find_btf()

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.
