Oleg Girko and smokku sx/ssl.c: fix undefined behaviour with openssl-1.1
BN_dec2bn in OpenSSL 1.1 requires its first argument to point to
either pointer to initialised BIGNUM or NULL.
Using pointer to uninitialised pointer to BIGNUM is undefined behaviour
causing coredumps or other memory corruption.

This change fixes missing initialisation overlooked when porting
to OpenSSL 1.1 API.

Thanks for downloading jabberd2. Below are some basic instructions to get you started. Complete documentation is available at http://jabberd2.org/

-- the jabberd team

Required packages:

Optional packages:


% ./configure
% make
% make install

Options to ./configure:

% ./configure --help


Edit $prefix/etc/(router|sm|c2s|s2s).xml to taste. In particular, make sure you setup for your choice of data storage correctly. If you're using the Berkeley DB backend, you'll need to create /var/run/jabberd and sets its permissions so that the server processes can find it.

If you're using a SQL backend, you'll need to create an account for the server to use, and create the tables. Load db-setup.mysql or db-setup.pgsql from the tools/ directory into your database to do this.

If you plan to use the jabberd wrapper script, make sure you look at the paths in the $prefix/etc/jabber/jabberd.cfg.


You can either run all of the pieces separately:

% $prefix/bin/router &
% $prefix/bin/s2s &
% $prefix/bin/sm &
% $prefix/bin/c2s &

Or you can run them all from the jabberd wrapper script:

% $prefix/jabberd &

All the processes can take the following switches:

-c use an alternate config file
-D output lots of debugging info (if compiled with --enable-debug)


Please see NEWS file.


When requesting assistance, please note that the following things can provide useful information which may assist with finding your problem:

  • debug logs (compile with --enable-debug and run with -D)
  • running components seperately (ie without the wrapper script)
  • config.log

Please try to provide as much relevant information as possible when reporting problems - it will make helping you much easier.
