This most importantly avoids races between dlopen and friends and fork, potentially resulting in dead locks in the child when it itself tries to acquire locks. Rename __atomic_fork to __locked_fork and give it &errno as argument. rtld and libc use different storage, so the initial version would incorrectly report the failure reason for fork(). There is still a small race condition inside ld.elf_so as it doesn't use thread-safe errno internally, but that's a more contained internal issue. |
