[OpenWrt-Devel] [PATCH ubus 00/16] GitLab CI, tests, fuzzing, fixes and improvements

[Petr Štetiar]

Hi,

this patch series adds GitLab CI support, unit tests passed through Valgrind,
unit tests covered with Clang's {Address,Leak,UndefinedBehavior}Sanitizer,
fuzzing with libFuzzer and bunch of fixes uncovered by Coverity and this new
CI test suite.

Petr Štetiar (16):
  cmake: enable extra compiler checks
  ubusd: fix comparison of integers of different signs
  ubusd/libubus-io: fix variable sized struct position warning
  iron out all extra compiler warnings
  libubus: fix incompatible pointer types assigment
  add initial GitLab CI support
  examples: remove dead increments
  refactor ubusd.c into reusable ubusd_library
  add fuzzer and cram based unit tests
  lua: workaround false positive dereference of null pointer
  lua: ubus_lua_do_subscribe: fix copy&paste error
  workaround possibly false positive uses of memory after it is freed
  ubus_common: remove duplicate ARRAY_SIZE and add missing include
  ubusd_monitor: fix possible null pointer dereference
  ubus_monitor: workaround possibly false positive uses of memory after
    it is freed
  fix blob parsing vulnerability by using blob_parse_untrusted
