Status as of 2.1.2019 is the same:

Two tests were skipped due to wrong Galera lib version:

"galera.galera#505 'innodb' [ skipped ] Test requires Galera library version >= 25.3.24
galera.galera_defaults 'innodb' [ skipped ] Test requires Galera library version >= 25.3.20"

But at the same time:
"wsrep loader: [INFO] wsrep_load(): Galera 26.4.0(r4454) by Codership Oy <info@codership.com> loaded successfully."

Status as of 3.1.2019 is the same except that galera.galera#505 and galera.galera_defaults was passed, not skipped as previous time.

temeo [6:11 PM]:
"galera_autoinc_sst_mariabackup failure leaves sometimes socat process lingering on background and it reserves the SST port. This may make some following tests on same MTR worker to fail because the SST fails when starting servers for the test."

Status as of 7.1.2019: 10 failed tests (last time there were only 6):

"Completed: Failed 10/248 tests, 95.97% were successful.

Failing test(s): galera.galera_bf_lock_wait galera.galera_concurrent_ctas galera.galera_autoinc_sst_mariabackup galera.galera_gcs_fragment galera.galera_gcs_max_packet_size galera.galera_gtid_slave galera.galera_gtid_slave_sst_rsync galera.galera_ist_mariabackup galera.galera_sst_rsync2 galera.galera_sst_rsync_data_dir"

Here you are the new failed tests in comparing with test run on 04.01.2019:
galera.galera_bf_lock_wait
galera.galera_gcs_max_packet_size
galera.galera_gtid_slave
galera.galera_gtid_slave_sst_rsync
galera.galera_ist_mariabackup

All of these tests being running separately have been passed successfully:

galera.galera_bf_lock_wait
galera.galera_gcs_max_packet_size
galera.galera_gtid_slave
galera.galera_ist_mariabackup

And only galera.galera_gtid_slave_sst_rsync has failed.
But one time it has passed anyway:

galera.galera_gtid_slave_sst_rsync 'innodb' [ pass ] 42818
galera.galera_gtid_slave_sst_rsync 'innodb' [ 2 fail ]

Status as of 9.1.2019: there is only one failed test remains:

"Completed: Failed 1/240 tests, 99.58% were successful.

Failing test(s): galera.galera_gcs_fragment"

Status as of 10.1.2019:

"Completed: All 240 tests were successful."

Just MTR's internal check of the test case 'galera.galera#500' failed:

"Check of testcase failed for: galera.galera_bf_abort_shutdown galera.galera#500
This means that the test case does not preserve the state that existed
before the test case was executed. Most likely the test case did not
do a proper clean-up. It could also be caused by the previous test run
by this thread, if the server wasn't restarted.

-AUTO_INCREMENT_OFFSET 1
+AUTO_INCREMENT_OFFSET 2"

I.e. the test is not preserving the value of the global variable `auto_increment_offset`.
