get ip of user executed program

ilansch · 05-28-2017, 03:59 AM

In my kernel module driver, during the execution of program (e.g mkdir) I need to find out the IP of the currently logged in client that executed this program.

One solution is to climb up in the process tree, go to init process, then start going down in the process tree, look for sshd, cross between the user id and the sshd session, perform a netstat and get the Foreign Address.

Is the a better efficient way to get the ip of the user ?

/proc/$$/task/$$/net/ip_conntrack
might be related. Interesting project: "kernel module driver" that ?executes programs?
Let us know (more); best wishes. (a link)

my lkm does not execute programs.

Oh, sorry. Maybe lkm related to prior VFS post here.
Might the ip_conntrack be of any value here?

You didn't specify that

Yeah, that comes up on some closed-sourced stuff I have.
How about pstree ??

Have fun!
