Ricardo Cañuelo 2a79a7e8b6 selftests/lkdtm: Disable CONFIG_UBSAN_TRAP in test config ... [ Upstream commit cf77bf6988 ] The lkdtm selftest config fragment enables CONFIG_UBSAN_TRAP to make the ARRAY_BOUNDS test kill the calling process when an out-of-bound access is detected by UBSAN. However, after this [1] commit, UBSAN is triggered under many new scenarios that weren't detected before, such as in struct definitions with fixed-size trailing arrays used as flexible arrays. As a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to enable except for specific situations. `make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config for all selftests, which makes many of them fail because of system hangs during boot. This change removes the config option from the lkdtm kselftest and configures the ARRAY_BOUNDS test to look for UBSAN reports rather than relying on the calling process being killed.
