The local function get_last/4 has been renamed to get_last_iq/4, since
it converts the result of get_last/2 (typically {ok, TimeStamp, Status})
to an iq packet.
According to XEP-0012, 4. Online User Query, "if the requesting entity
is not authorized to view the user's presence information (normally via
a presence subscription as defined in XMPP IM), the user's server MUST
NOT deliver the IQ-get to an available resource but instead MUST return
a <forbidden/> error in response to the last activity request."
So check for a subscription of from of the jid and bare jid and whether
outgoing presences to From are allowed.
Fixes problem 3 of EJAB-1158.
For EJAB-1045, the special NS_VCARD block for handling incoming vcard
iqs on behalf of clients has already been restricted to cases where the
user or resource part of the recipient is empty. But then the packets
should not have been routed to the c2s process anyway. This patch
completely removes it.
is_privacy_allow is only used in ejabberd_c2s:handle_info/3 to determine
for a few presence types whether the packet is allowed to be forwarded
to the user's client. This only makes sense if To#jid.user and
To#jid.server match StateData#state.user and StateData#state.server.
Also, add the atom in as parameter to a new argument Dir of
is_privacy_allow and extract from that function
privacy_check_packet(StateData, From, To, Packet, Dir) which runs the
privavcy check without converting allow/deny to true/false.
The change for EJAB-1271 to change the direction of the privacy check
from out to in violates the idea that the check should imitate a
subscription state check of from. Rather correct the order of the From
and To parameters.
Modules configured by the administrator normally should not be treated
as optional, so a exception (error, exit, throw) to start them should not
be caught and logged only.
This patch re-raises a caught exception instead of ignoring the
exception and inserting the module's opts on success. That way
gen_mod:get_module_opt/4 should work while calling Module:start/2.
When a (non-frontend) socket module without any custom receiver fails to
start, the newly created ejabberd_receiver process needs to be properly
closed.
Changes included:
* Remove var in fixed field because Gajim and Tkabber display it to user
* Add workaround for Psi's overlap fields
* Add var=url attribute, required by Psi to display the field
* Provide the image URL as a copy-able form field
This is required in order to suppress error messages like
"File operation error: eacces" when ejabberd was started from directory,
which is not readable by INSTALLUSER (/root, for example). See rhbz #564686:
