You can't definitively do it. You can get filp from struct sock -> struct socket -> struct file And the forward lookup path you can get filp from fd -> struct task_struct -> struct files_struct -> struct file You can compare the filp's and see which match. However multiple fd's can point to the same filp (as in dup(2)), so you are never guaranteed a 1:1 mapping. At best you can tell which fd(s) -- note possibly plural -- are pointing to the socket (or file). cheers, -chris -- Linux Security Modules http://lsm.immunix.org http://lsm.bkbits.net -- Kernelnewbies: Help each other learn about the Linux kernel.
