I see, the /proc/*/fd/* objects seem "confused": are they symlinks,
hardlinks, or open file descriptors? I guess should always act as
the latter, where access mode flags (O_RDONLY or O_RDWR) are set at
open() and not changeable afterwards in fcntl(). Any open() on them
should behave as a dup().
Paul, in authentic kernels /proc/<PID>/fd/<FD> are symlinks, not
anything other. There're no such publicly accessible file objects,
as file descriptors, there're only files (including special ones),
directories and symlinks. But the above words don't necessary relate
to patched kernels like distributed by third parties.
