+ * - FD passing tests: Child creates PTY, parent receives FD (demonstrates
+ * security issue)
+ *
+ * SECURITY VULNERABILITY DEMONSTRATION:
+ * FD passing tests show that TIOCSTI uses CURRENT process credentials, not
+ * opener credentials. This means privileged processes can be given FDs from
+ * unprivileged processes and successfully perform TIOCSTI operations that the
+ * unprivileged process couldn't do directly.
+ *
+ * Attack scenario:
+ * 1. Unprivileged process opens TTY (direct TIOCSTI fails due to lack of
+ * privileges)
+ * 2. Unprivileged process passes FD to privileged process via SCM_RIGHTS
+ * 3. Privileged process can use TIOCSTI on the FD (succeeds due to its
+ * privileges)
+ * 4. Result: Effective privilege escalation via file descriptor passing
+ *
+ * This matches the kernel logic in tiocsti():
+ * 1. if (!tty_legacy_tiocsti && !capable(CAP_SYS_ADMIN)) return -EIO;
+ * 2. if ((current->signal->tty != tty) && !capable(CAP_SYS_ADMIN))
+ * return -EPERM;
+ * Note: Both checks use capable() on CURRENT process, not FD opener!
+ *
+ * If the file credentials were also checked along with the capable() checks
+ * then the results for FD pass tests would be consistent with the basic tests.
