Reported in #3527. Add hostname matching function, and specify SNI
Also, OTP 23 dropped backwards compatibility for 0, 1, 2 values for verify, so
replace with combination of verify_none/verify_peer and fail_if_no_peer_cert
as appropriate
Don't accept loopback addresses as TURN peers by default. This makes
sure the TURN service won't allow remote clients to access local UDP
services.
However, this will break the case where the 'turn_ipv4_address' was set
to 127.0.0.1 as fallback and TURN worked "by accident" if both clients
were using the same TURN service. The service then talked to itself on
the loopback interface.
Support systemd's watchdog feature and enable it by default in the unit
file, so that ejabberd is auto-restarted if the VM becomes unresponsive.
Also, set the systemd startup type to 'notify', so that startup of
followup units is delayed until ejabberd signals readiness. While at
it, also notify systemd of configuration reload and shutdown states.
Note: "NotifyAccess=all" is required as long as "ejabberdctl foreground"
runs the VM as a new child process, rather than "exec"ing it. This way,
systemd views the ejabberdctl process itself as the main service
process, and would discard notifications from other processes by
default.
This stop overriding store_type when anonymous is enabled with other
auth modules, we don't really need that since anonymous is not taking
passwords anyway, and this was disabling scram mechanisms.
This fixes issue #2803.
This together with last history message is used by room_unused_* command
to determine for how long room was not used, this change allow us to skip
checking history, and works even when history is disabled.
This required adding hibernation time to data stored for room to be able
determine how old was a room, rooms that aren't stored with that
information will use node start time as timestamp for that.
This caused garbled text in some places in webadmin when using language
that used characters > 128.
Thanks to chengshq for noticing this and providing preliminary patch.
By doing this check_password that returned info about mismatched password
caused user_exists checks performed after that to return wrongly that
account doesn't exist.
Previously c2s was free to generate data to send in unlimited manner, and
just generate queue of messages that are waiting to be send. This could lead to
hitting timouts in stream management ack handling (if c2s generate lot of
packages, after which <r> request was sent, client could even not receive it
before timeout was triggered on server waiting for corresponding <a>).
This changes makes c2s process wait for data being sent to tcp socket
associated with websocket connection, which should help with this problem.
Since commit de91618070, it was no longer
possible to configure mod_register so that only account removal (i.e.,
no registration) is permitted. Revert to the previous behavior which
allows admins to freely configure account registration and removal via
separate access rules.
Sometimes we can observer combinations of subscription/ask that shouldn't
happen normally, but can be generated with api calls, let's try to handle
that gracefully instead of crashing.
Only non-persistent rooms that we are storing are those that were hibernated
but also have mucsub subscribers in them. I don't think it makes sense to
destroy those rooms on restart/reload if we didn't destroy them in first
place when last member did leave room, let just handle those rooms like
they are persistent, and kill them only when all user unsubscribe from them
or they are destroyed from api.
By default, the logger_std_h module shipped with OTP 21.0 and newer
reads the log file information prior to each and every write operation.
This is done to play well with external log rotation tools.
In order to minimize the performance penalty in situations where the log
file is flooded, configure logger_std_h to skip reading the file
information as long as no more than one second has passed since it was
last read.
Let misc:uri_parse/1 return default HTTP(S) port number if the URL
doesn't specify a port number, analogous to the behavior when
USE_OLD_HTTP_URI is defined.
The uri_string:parse/1 function returns the URI elements as strings or
as binaries depending on the input. Make sure misc:uri_parse/1 returns
strings in both cases, analogous to the behavior when USE_OLD_HTTP_URI
is defined.
During XEP-0198 resumption, the ejabberd_c2s process that handles the
new connection reopens the ejabberd_sm session of the old one. Since
commit b4770815c0, the new process adds
the new session table entry before the old process removes the old one.
While adding the new one, ejabberd_sm checks for old sessions to
replace. This check assumes old SIDs compare lower than new ones. This
assumption didn't necessarily hold for the session resumption case,
where the old SID's timestamp was copied over to the new SID and only
the PID was updated. Therefore, the new process was killed if the new
PID happened to be smaller than the old one.
Fix this by having mod_stream_mgmt use its own SM-ID rather than copying
over the old SID's timestamp to the new SID.
Thanks to Thilo Molitor and Friedrich Altheide for reporting the issue,
and to Thomas Leister for his help with debugging it.
The new 'turn_blacklist' listener option allows for specifying one or
more IP addresses and/or subnet addresses/masks. The TURN server will
refuse to relay traffic from/to blacklisted IP addresses. By default,
Teredo and 6to4 addresses are blacklisted, as mandated by RFC 6156
(section 9.1).
Omit the 'tcp' and 'stuns' services from the list of example 'services'
in the documentation. For typical use cases, those are less interesting
than 'udp' and 'turns' services.
Increase the default lifetime of temporary credentials to 12 hours.
ejabberd's built-in TURN server re-queries the temporary password from
mod_stun_disco whenever a TURN client attempts to refresh an allocation,
and mod_stun_disco will only return the password as long as the
credentials didn't expire. Therefore, the credentials lifetime
effectively limits the maximum lifetime of a TURN allocation when
ejabberd's TURN service is used, so the default value shouldn't be too
short.
Previously we only send that presence to direct presence recipients if
client also sent general self presence (without to attribute).
This should help with issue #3245
If a TCP connection was closed before the socket was handed over to a
supervised child process, let the supervisor terminate the process
rather than killing it directly. This avoids crash log entries
generated by the supervisor.
The default value for the 'max_fsm_queue' option was set to 10000 in
commit 79685da90b, and that value is still
documented to be the default. It was (probably unintentionally) changed
to 5000 in commit 03de853e4f.
It makes sense to keep it larger than the value of mod_stream_mgmt's
'max_ack_queue' option.
If the 'offer_local_services' option isn't set to 'false', log an [info]
message for each auto-discovered ejabberd_stun listener on startup (and
on configuration reload).
In some IPv6-only networks, hostnames that have no AAAA record are
resolved to an IPv6 address that's mapped to the host's IPv4 address.
This allows the IPv6-only clients to communicate with IPv4-only services
such as ejabberd's built-in STUN/TURN server. If STUN/TURN clients try
to contact the IPv4 address directly rather than using the mapped IPv6
address, the connection will fail.
Therefore, try to resolve the IP address of local ejabberd_stun services
to the hostname and announce that hostname rather than the IP address if
(and only if) the hostname resolves back to the original IP address, and
not to any additional IPv4 or IPv6 address(es).
This can (and should) be reverted once IPv6 support is added to
ejabberd's built-in STUN/TURN server.
These days, STUN/TURN authentication can be performed with ephemeral
credentials, where the REALM is irrelevant. Therefore, just log an
[info] message rather than a [warning] in the case where no
authentication REALM is configured but multiple virtual domains exist.
Add the 'mod_stun_disco' module, which allows XMPP clients to discover
STUN/TURN services and to obtain temporary credentials for using them as
per XEP-0215: External Service Discovery. The temporary credentials
handed out to clients have the format described in:
https://tools.ietf.org/html/draft-uberti-behave-turn-rest-00
Also add the new module to the example configuration file.
Closes#2947.
We really don't need those, and thanks to each individual room having
different hash (as one of hashed data is room description) we end with
lot of data that we really don't need.
Make sure modules won't be reloaded before listeners. This is necessary
to allow the (not yet committed) 'mod_stun_disco' module to parse the
listener configuration after configuration reloads.
The 'turn_ip' option validator doesn't accept an inet:ip4_address()
tuple.
While at it, change the logic to only perform the fallback address
lookup if no 'turn_ip' is configured (analogous to the fallback
mechanism for the case where the 'auth_realm' is undefined).
Try to resolve the local hostname, use the result as the default
'turn_ip', and only log a warning if that fails. Using the local
hostname's address by default is analogous to mod_proxy65's behavior.
When another connection is inserting something to spool at this same time
as we do pop_messages, it's possible that insert will happen between we
fetch messages and delete them, so we effectively will delete it without
delivering it to client. This change catch this situation and restart
transaction, so we should always have consistent results.
It looks like old version of Smack don't accept request that are have
from sent to sender jid, but are only working when jid is set to server
address. This is also how it looks in old xmpp rfc examples.
Messages that are received when no c2s is active will be stored in offline,
even when mam archived them, so i don't think we should be doing something
different in this case.
Between receiving resume request and being closed by new session, it's
possible (even if not very likely) that new messages would arrive to
process that is resumed. In that case try to reroute messages that were
received after we sent resume reply to new process.
Calling sync version of xmpp_stream_in/out:stop could lead to messages
never being processed by c2s process if they were queued in p1_server.
This could be reproduced by when having messages in offline storage,
starting sessions, enabling stream_mgmt, sending initial presence, and then immediately
</stream:stream>, messages that mod_offline would send process would not
be bounced back by stream_mgmt.
How to reproduce the problems fixed by this commit:
Create temporary room, other account subscribes, and owner leaves
Unsubscribe that account with the command: ejabberdctl unsubscribe_room ...
There is possibilty that between c2s process unregistering itself from sm
and terminating, some other process could try to send something to c2s,
which could result in messages to triggering mam/offline hooks, and causing
them not to be stored in any way.
Cockroachdb doesn't properly handle escaping of _ in like expressions,
having "like ... escape '\'" makes it work, by disabling optimization that
causes this broken behaviour
Previous method of processing files, could lead to mixing events generated
by parsers for multiple files, where we could get in inconsistant state.
After this change we gather all events generated by parser for single file,
before we start parsing any included file.
This fixes issue #3166
The 'reload_config' and 'dump_config' calls are expected to yield a
'rescode' result, which means they must return 'ok' (rather than a
tuple) on success.
Fixes#3170.
We encoded scramed password with base64 when exporting, but didn't apply
reverse operation on import, this adds base64 decoding on import.
This fixes issue #3167.
