Pekka Paalanen 4c0bdbfde9 xwayland: do not snprintf() after fork() Between fork() and exec() in the child process it is only safe to use async-signal-safe functions. Surprisingly, snprintf() is not such function. See e.g. https://stackoverflow.com/a/6771799 and how snprintf is not listed in signal-safety(7) manual. Therefore we must prepare the fd argument strings before fork(). That is only possible if we also do not dup() fd in the child process. Hence we remove the close-on-exec flag instead in the child process which has copies of the parent's file descriptors. Fortunately fcntl() is safe. struct fdstr is helping to reduce code clutter a bit. Additionally, if fork() fails, we now clean up the fds we created.
