linux-security-module: Path of task via LSM

Path of task via LSM

Is there a way to retrieve the full path of the currently running task via a task_struct or similar structure from the view of the LSM? Currently, the work I am doing with LSM design requires hooking into bprm_alloc_security in order to read the linux_binprm structure which contains the path of the application as it was run. Is there a similar way to access the full path dynamically say if I'm checking a socket based LSM hook which does not receive the linux_binprm structure

I have been unsuccessful in using dentry and vfsmnt from the current task_struct via the d_path() lookup function. -
