can you expand on why this might be a problem, as far I can tell the syscall is in fs/open.c
it seems very simple to me
asmlinkage long sys_vhangup(void) { if (capable(CAP_SYS_TTY_CONFIG)) { tty_vhangup(current->tty); return 0; } return -EPERM; }
basically, we call tty_vhangup on the process's tty.
if tty_vhangup was the syscall, I could see this being a problem, but as sys_vhangup can only operate on the what the task_struct has, how is it a problem?
thanks,
