I'd have a couple of questions regarding your usage of readdir() [1].

man page [2]:
> In the current POSIX.1 specification (POSIX.1-2008), readdir() is not
> required to be thread-safe.  However, in modern implementations

belle-sip must work not only on GNU/Linux with glibc, but also on other
platforms or different libc implementations (e.g. musl, Android's
bionic). Are you sure they are also modern enough to be thread-safe?

man page [2]:
> In cases where multiple threads must read from the same directory
> stream, using readdir() with external synchronization is still
> preferable to the use of the deprecated readdir_r(3) function.

Have you ensured, that belle-sip does never make such concurrent calls
(for the same directory stream), which after switch to readdir() must
be explicitly protected?
