Fix SEGV on re-raising NoMemoryError
2016-01-19Fix SEGV on re-raising NoMemoryErrorKouhei Sutou
Think about the following Ruby script: segv.rb: begin lambda do lambda do "x" * 1000 # NoMemoryError end.call end.call rescue raise end If memory can't allocate after `"x" * 1000`, mruby crashes. Because L_RAISE: block in mrb_vm_exec() calls mrb_env_unshare() via cipop() and mrb_env_unshare() uses allocated memory without NULL check: L_RAISE: block: L_RAISE: // ... while (ci[0].ridx == ci[-1].ridx) { cipop(mrb); // ... } cipop(): static void cipop(mrb_state *mrb) { struct mrb_context *c = mrb->c; if (c->ci->env) { mrb_env_unshare(mrb, c->ci->env); } c->ci--; } mrb_env_unshare(): MRB_API void mrb_env_unshare(mrb_state *mrb, struct REnv *e) { size_t len = (size_t)MRB_ENV_STACK_LEN(e); // p is NULL in this case mrb_value *p = (mrb_value *)mrb_malloc(mrb, sizeof(mrb_value)*len); MRB_ENV_UNSHARE_STACK(e); if (len > 0) { stack_copy(p, e->stack, len); // p is NULL but used. It causes SEGV. } e->stack = p; mrb_write_barrier(mrb, (struct RBasic *)e); } To solve the SEGV, this change always raises NoMemoryError even when realloc() is failed after the first NoMemoryError in mrb_realloc(). mrb_unv_unshare() doesn't need to check NULL with this change. But it causes infinite loop in the following while: L_RAISE: // ... while (ci[0].ridx == ci[-1].ridx) { cipop(mrb); // ... } Because cipop() never pops ci. This change includes cipop() change. The change pops ci even when mrb_unv_unshare() is failed by NoMemoryError. This case can be reproduced by the following program: #include <stdlib.h> #include <mruby.h> #include <mruby/compile.h> static void * allocf(mrb_state *mrb, void *ptr, size_t size, void *ud) { static mrb_bool always_fail = FALSE; if (size == 1001) { always_fail = TRUE; } if (always_fail) { return NULL; } if (size == 0) { free(ptr); return NULL; } else { return realloc(ptr, size); } } int main(int argc, char **argv) { mrb_state *mrb; mrbc_context *c; FILE *file; mrb = mrb_open_allocf(allocf, NULL); c = mrbc_context_new(mrb); file = fopen(argv[1], "r"); mrb_load_file_cxt(mrb, file, c); fclose(file); mrbc_context_free(mrb, c); mrb_close(mrb); return EXIT_SUCCESS; } Try the following command lines: % cc -I include -L build/host/lib -O0 -g3 -o no-memory no-memory.c -lmruby -lm % ./no-memory segv.rb
