OK, for the record and the archive :-) - I've now tried to follow the
twisted maze of manage.c to understand why one or the other signal
is sent.
This is happening inside man_reset_client_socket(), in this bit of code:
if (!exiting)
{
...
if (man->settings.flags & MF_SIGNAL) {
int mysig = man_mod_signal (man, SIGUSR1);
if (mysig >= 0)
{
msg (D_MANAGEMENT, "MANAGEMENT: Triggering management signal");
throw_signal_soft (mysig, "management-disconnect");
}
}
if (man->settings.flags & MF_CONNECT_AS_CLIENT)
{
msg (D_MANAGEMENT, "MANAGEMENT: Triggering management exit");
throw_signal_soft (SIGTERM, "management-exit");
}
else
man_listen (man);
}
MF_CONNECT_AS_CLIENT is set by options.c if --management-client is
used, MF_SIGNAL is set by options.c if --management-signal is used - but
note that the "if (... MF_SIGNAL)" clause doesn't apply to the SIGTERM
signalling.
So, if I read this right
- SIGTERM will *always* be sent upon management-disconnect if
--management-client has been used, even if --management-signal
is not set
- SIGUSR1 will be sent upon disconnect *if* requested by --management-signal
(subject to remapping, but not automatically remapped)
if that analysis is correct, I'd re-word the proposed new text in the manpage
somewhat. Suggested wording:
.B \-\-management-signal
Send SIGUSR1 signal to OpenVPN if management session disconnects
(subject to remapping by \-\-remap-usr1).
This is useful when you wish to disconnect an OpenVPN session on
user logoff. If \-\-management-client is used, a SIGTERM signal
will always be sent on disconnect, even if \-\-management-signal is
not set.
