Consumers match on negative errno constants -- xs_tls_handshake_done() has switch (status) { case 0: case -EACCES: case -ETIMEDOUT: lower_transport->xprt_err = status; break; default: lower_transport->xprt_err = -EACCES; } so the API as designed expects callers to pass positive errno values that the tlshd shim then negates. Three internal callers in handshake_nl_accept_doit(), the net-exit drain, and a kunit test follow kernel convention and pass negative errnos -- -EIO, -ETIMEDOUT, -ETIMEDOUT. The implicit conversion to unsigned int turns -ETIMEDOUT into 0xFFFFFF92; the subsequent -status in tls_handshake_done() wraps back to 110, the consumer's switch falls through, and the xprt reports -EACCES on what should be -ETIMEDOUT or -EIO. Fix the API rather than the call sites. The natural kernel convention is negative errno in, negative errno out. Change handshake_complete() and hp_done to take int status, drop the negation in tls_handshake_done(), and negate once in handshake_nl_done_doit() where status arrives from the wire as an unsigned netlink attribute. The three internal callers were already correct under that convention and need no change. At the same wire boundary, declare MAX_ERRNO as the netlink policy upper bound for HANDSHAKE_A_DONE_STATUS. Attribute validation rejects out-of-range values before handshake_nl_done_doit() runs, and negating a bounded u32 there stays within int range -- closing the UBSAN-visible signed- integer overflow that an unconstrained u32 would invoke.

So remove its documentation so that it doesn't get used in production and people get silly ideas. It is meant strictly for debugging; and if a chicken bit for properly disabling a feature is warranted, then that would need proper enablement. No functional changes.
