The ioctl code needs a good rewrite indeed. However, I'm more concerned
about that:
/usr/include/bits/socket.h: In function ‘__cmsg_nxthdr’:
/usr/include/bits/socket.h:315:12: error: cast increases required alignment of
target type [-Werror=cast-align]
__cmsg = (struct cmsghdr *) ((unsigned char *) __cmsg
The minimal reproducible file is a one-liner:
#include <netdb.h>
Running
gcc-8 -Wsystem-headers -Wcast-align=strict -Werror -O2 -c 1.c
produces the error above.
Although that's annoying, it's a false alarm, since the code properly aligns the
pointer before using it by using CMSG_ALIGN. The warning in rtapelib.c, though,
is not so obviously a false alarm.
