Forward ioctl(TCSETSF) calls on host ttys to the host kernel.
We already forward TCSETS and TCSETSW. TCSETSF is roughly equivalent but discards pending input. The filters were relaxed to allow host ioctls with TCSETSF argument. This fixes programs like "passwd" that prevent user input from being displayed on the terminal. Before: root@b8a0240fc836:/# passwd Enter new UNIX password: 123 Retype new UNIX password: 123 passwd: password updated successfully After: root@ae6f5dabe402:/# passwd Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully PiperOrigin-RevId: 214869788 Change-Id: I31b4d1373c1388f7b51d0f2f45ce40aa8e8b0b58
