openssh 8.1p1 related "bug or no bug"

[pradeep kumar]

Hi,

One of the debug statement is removed in mux.c and there is no history for
the same. The line number after 1989.

 switch (type) {
case MUX_S_SESSION_OPENED:
if ((r = sshbuf_get_u32(m, &sid)) != 0)
fatal("%s: decode ID: %s", __func__, ssh_err(r));
debug("%s: master session id: %u", __func__, sid); <------------ This
particular line is removed in oepnssh 8.1p1
break;

This is a very useful statement to check when CONTROLPERSIST feature is
used. This gives out the "master session id: sid" when ssh is run in debug
mode.

Could you please check whether this was deliberately removed or this was
accidentally removed.

Thanks and Regards,
Pradeep
