[pkg-wpa-devel] Bug#618277: PHASE mismatch in ifupdown script

[Tormod Volden]

I agree that nowadays this is usually run through dbus and
network-manager and not the ifupdown and /etc/interfaces way, but the
result is the same. Please look at
/etc/NetworkManager/dispatcher.d/01ifupdown - it sets $PHASE and does
run-parts on the corresponding /etc/network/if-XXX.d directory.

So in your example above, when "run-parts: executing
/etc/network/if-down.d/wpasupplicant" is executed, $PHASE is set to
"down". And the "pre-down" clause can not be executed since there is
no if-pre-down.d file.

You do agree that any post-up and pre-down clauses in ifupdown.sh will
not be run, right? In some cases they will not be reached anyway
because do_start() and do_stop() /exit/ the whole script, but in some
cases do_start() and do_stop() simply /return/ and the script
continues into these "case $PHASE" clauses. Maybe this is not the
majority of user cases (and not yours) but in these cases I think
things are not working as intended. Or would you think these clauses
are never reached by anyone and should rather be removed?

If by "this process" you refer to wpa_supplicant, I corrected that in
the following message which you might have missed.
