Added new test scenario in galera.galera_bf_kill test to make the issue surface. The tetst scenario has a multi statement transaction containing a KILL command. When the KILL is submitted, another transaction is replicated, which causes BF abort for the KILL command processing. Handling BF abort rollback while executing KILL command causes node hanging, in this scenario. sql_kill() and sql_kill_user() functions have now fix, to perform implicit commit before starting the KILL command execution. BEcause of the implicit commit, the KILL execution will not happen inside transaction context anymore. Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
