MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.
