In the mm struct you have the struct vm_area_struct (mmap entry)... this struct contains the struct file (vm_file entry) and then you can get the f_path and f_mnt.

Assunto: Path of task via LSM
Data: 27/11/07 11:19
> Is there a way to retrieve the full path of the currently running task

> Currently, the work I am doing with LSM design requires hooking into

> socket based LSM hook which does not receive the linux_binprm
> I have been unsuccessful in using dentry and vfsmnt from the current
> task_struct via the d_path() lookup function.
