Javier Jaramago Fernández	864535d3f9	Added support for GCC 4.8 and removed per-module metrics initialization functions ... - GCC 4.8 and 5 have issues with uniform initialization syntax, for this reason, all it's uses have been replaced with assignements. - Per-module metrics initialization functions are no longer required, they have been replaced with the new generic ones.	6 years ago

René Cannaò	c28deb7c7d	Generalize the use of session variables ... Added new array mysql_tracked_variables[] that defines the tracked variables. Ideally, tracking a new session variable will requires adding only a couple of lines of code. Removed session variables from mysql_thread_variables_names: - now both MySQL_Threads_Handler::get_variables_list() and MySQL_Threads_Handler::has_variable() rely on mysql_tracked_variables[] Simplified MySQL_Variables, as it now also uses mysql_tracked_variables[] . Simplify parser in MySQL_Session Generalized code to handle two variables together: - sql_auto_is_null - sql_safe_updates Migrating more session variables to new algorithm - collation_connection - net_write_timeout - max_join_size Migrating more session variables to new algorithm - collation_connection - net_write_timeout - max_join_size	6 years ago

René Cannaò	e9dc7a9b60	Implementation of SQLI fingerprints whitelist ... libsqlinjection generates a lot of false positives. This commit introduces a new table: mysql_firewall_whitelist_sqli_fingerprints This table can list fingerprints generated by libsqlinjection: if the fingerprint is listed in this table, proxysql will consider it as a false positive.

René Cannaò	485d313514	Further development of firewall whitelist. ... * introduced 2 new variables: - mysql-firewall_whitelist_enabled : defines if the firewall with whitelist algorithm is enabled or not - firewall_whitelist_errormsg : error message returned to the client if an error message is not already set * Query_Processor returns firewall_whitelist_mode to the calling MySQL_Session, but the logging on error log currently happens within the Query_Processor itself * if mysql-firewall_whitelist_enabled is turned on and a user it is not found in mysql_firewall_whitelist_users , the default behavior is that query is rejected * lookup on mysql_firewall_whitelist_users happens for username@ip (specific IP) and username@'' (all IPs) . Match on network subnet is currently not implemented * implemented SAVE MYSQL FIREWALL FROM RUNTIME * fixed implementation of SAVE MYSQL FIREWALL TO DISK * runtime configuration can be viewed in runtime_mysql_firewall_whitelist_rules and runtime_mysql_firewall_whitelist_users	6 years ago
