Subject: Re: open sockets from task_struct

(reposted because I remember kernel.org mentioning that HTML email is 
verboten or something like that---Sorry!)

I know that on the user-space side any open handles can be seen in the 
/proc/<pid>/fd directory (<pid> is whatever process you're interested in).
Assuming you're talking about reading this from kernel space, I'd look 
at what the procfs filesystem is doing and learn from that.
Sockets and block/char devices are listed like any other file, the list 
is based on file handles.
