* In ejabberd_s2s_out:wait_for_feature_request/2, the domain to use for
looking up domain_certfile options is #state.myname and not
#state.server
* If s2s_certfile is not specified, connect should still be part of the
tls options used by ejabberd_s2s_out
* Add #state.server to ejabberd_s2s_in processes and store the to
attribute in :wait_for_stream/2. Then use that server in
:wait_for_feature_request/2 to change the tls options like in
ejabberd_s2s_out.
Fixes EJAB-1086.
If the callback module has a socket type of independent and needs to
create the listener itself, do not pre-bind the port. The same holds if
there are errors in the listener configuration.
It may happen that auth or rdbms client tcp connections bind a local
socket to a port number required by a configered listener. The ejabberd
applications fails to start up and needs to be restarted.
In plain C you would bind(2) the listener port and listen(2) later on.
gen_tcp:listen/2 does not allow to separate these two steps though, so
another way is not to accept connections while start up. OTOH, the
kernel will syn/ack incoming connections and receive data, leaving them
in a buffer for the ejabberd to read from. If this is unwanted, a load
balancer would need to receive data from the ejabberd server before
adding the node to its pool.
This patch binds tcp ports while initializing the ejabberd_listener
process, storing ListenSockets in an ets table. start_listeners/0 will
reuse these ports later on.
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.
