Mao Han b399abe7c2 riscv: Fix perf record without libelf support ... This patch fix following perf record error by linking vdso.so with build id. perf.data perf.data.old [ perf record: Woken up 1 times to write data ] free(): double free detected in tcache 2 Aborted perf record use filename__read_build_id(util/symbol-minimal.c) to get build id when libelf is not supported. When vdso.so is linked without build id, the section size of PT_NOTE will be zero, buf size will realloc to zero and cause memory corruption.
