| H A D | thr_rtld.c | diff 217191 Sun Jan 09 12:48:01 MST 2011 kib Implement the __pthread_map_stacks_exec() for libthr. Stack creation code is changed to call _rtld_get_stack_prot() to get the stack protection right. There is a race where thread is created during dlopen() of dso that requires executable stacks. Then, _rtld_get_stack_prot() may return PROT_READ | PROT_WRITE, but thread is still not linked into the thread list. In this case, the callback misses the thread stack, and rechecks the required protection afterward. Reviewed by: davidxu |
