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.
