Nico Weber	7ffcc5a8b2	LibC: Implement file actions for posix_spawn	2020-06-19 22:11:38 +02:00
Nico Weber	e89a82a476	LibC: Add support for POSIX_SPAWN_RESETIDS ... This is possible now that seteuid() / setegid() are implemented.	2020-06-19 20:34:59 +02:00
Nico Weber	4720635aab	LibC: Add posix_spawn()! ... All the file actions stuff is still missing for now, as is POSIX_SPAWN_SETSCHEDULER (not sure what that's supposed to do) and POSIX_SPAWN_RESETIDS. Implemented in userspace for now. Once there are users, it'll likely make sense to make this a syscall for performance reasons. A simple test program of the form extern char **environ; int main(int argc, char* argv[]) { pid_t pid; char* args[] = { "ls", NULL }; posix_spawnp(&pid, "ls", nullptr, nullptr, args, environ); } works fine.	2020-06-17 18:49:06 +02:00
