irc/ircd-hybrid: Update to 8.2.44

Changes since 8.2.43:

• • Noteworthy changes in version 8.2.44 (2024-06-15)
• Fixed FTCBFS issue caused by ./configure using macros that lacked special handling for cross-compilation scenarios
• Fixed the issue where XLINE and UNXLINE were not working properly on servers within a cluster
• Command-line options now support both short (-c) and long (--configfile) formats. The available options are:
  • -c or --configfile for the configuration file
  • -k or --klinefile for the kline database file
  • -d or --dlinefile for the dline database file
  • -x or --xlinefile for the xline database file
  • -r or --resvfile for the resv database file
  • -l or --logfile for the log file
  • -p or --pidfile for the PID file
  • -f or --foreground to run in the foreground
  • -v or --version to print the version and exit
  • -h or --help to display help information
• The new IRC operator flag, message:mass, has been implemented. This flag controls access to sending mass messages using the NOTICE $$*.mask command.
• Upon connecting, a user will now receive a notice with their client certificate fingerprint, if provided.
• The INFO command now includes the serverinfo::name, serverinfo::sid, and`serverinfo::description` configuration options in its output.
• The STATS subsystem has been rewritten to support dynamic registration and unregistration of stats handlers. This allows modules to register and unregister their own stats handlers.
• Implemented hostname cloaking API to improve user privacy and security by obfuscating real IP addresses. The cloaking process uses CIDR masking, SHA3 hashing, and base32 encoding to generate secure and unique cloaked hostnames. The following configuration directives have been introduced:
  • cloak_enabled: Enable or disable hostname cloaking.
  • cloak_cidr_len_ipv4: CIDR length for IPv4 addresses used in hostname cloaking.
  • cloak_cidr_len_ipv6: CIDR length for IPv6 addresses used in hostname cloaking.
  • cloak_num_bits: Number of bits for the MAC computation used in hostname cloaking.
  • cloak_secret: Secret key used in the MAC computation for hostname cloaking.
  • cloak_suffix: Suffix appended to the cloaked hostname.
• Added user mode +x (cloak) to activate hostname cloaking for the user, replacing their real IP address with a cloaked hostname.
• The INFO command now includes the new cloaking configuration options in its output. The following cloaking-related configuration directives will be shown:
  • general::cloak_enabled
  • general::cloak_cidr_len_ipv4
  • general::cloak_cidr_len_ipv6
  • general::cloak_num_bits
  • general::cloak_secret (displayed as <REDACTED> for security)
  • general::cloak_suffix
