Bug#27145 EXTRA_ACL troubles The flag EXTRA_ACL is used in conjugation with our access checks, yet it is not clear what impact this flag has. This is a code clean up which replaces use of EXTRA_ACL with an explicit function parameter. The patch also fixes privilege checks for: - SHOW CREATE TABLE: The new privilege requirement is any privilege on the table-level. - CHECKSUM TABLE: Requires SELECT on the table level. - SHOW CREATE VIEW: Requires SHOW_VIEW and SELECT on the table level (just as the manual claims) - SHOW INDEX: Requires any privilege on any column combination. mysql-test/r/grant.result: * Error message now shows correct command (SHOW instead of SELECT) mysql-test/r/grant2.result: * Error message now shows correct command (SHOW instead of SELECT) mysql-test/r/grant4.result: * This test file tests privilege requirements for SHOW COLUMNS CREATE TABLE .. LIKE SHOW CREATE TABLE SHOW INDEX CHECKSUM TABLE SHOW CREATE VIEW mysql-test/r/information_schema_db.result: * Added SELECT privilege to testdb_2 as SHOW CREATE VIEW now demands this privilege as well as SHOW VIEW. mysql-test/r/outfile.result: * Changed error code mysql-test/r/view_grant.result: * Additional SELECT privilege is now needed for SHOW CREATE VIEW mysql-test/t/grant4.test: * This test file tests privilege requirements for SHOW COLUMNS CREATE TABLE .. LIKE SHOW CREATE TABLE SHOW INDEX CHECKSUM TABLE SHOW CREATE VIEW mysql-test/t/information_schema_db.test: * Added SELECT privilege to testdb_2 as SHOW CREATE VIEW now demands this privilege as well as SHOW VIEW. mysql-test/t/outfile.test: * Changed error code mysql-test/t/view_grant.test: * Additional SELECT privilege is now needed for SHOW CREATE VIEW sql/mysql_priv.h: * Replaced EXTRA_ACL with a parameter sql/sp_head.cc: * Replaced EXTRA_ACL with a parameter sql/sql_acl.cc: * Converted function documentation to doxygen and clarified some behaviors. * Changed value from uint to bool to better reflect its meaning. * Removed pointless variable orig_want_access * Added function has_any_table_level_privileges to help with requirements checks during SHOW CREATE TABLE. sql/sql_acl.h: * changed signature of check_grant() * introduced access control function has_any_table_leevl_privileges() sql/sql_base.cc: * Check_table_access has new signature sql/sql_cache.cc: * Check_table_access has new signature sql/sql_parse.cc: * Rewrote function documentation in doxygen comments for: check_access, check_table_acces, check_grant. * Removed EXTRA_ACL flag where it doesn't hold any meaningful purpose anymore and replaced it with a function parameter where any privileges on any column combination would satisfy the requirement. * Fixed privilege check for SHOW COLUMNS and SHOW INDEX * Modified check_table_access to gain clarity in what EXTRA_ACL actually does. * Modified check_access to gain clarity in what EXTRA_ACL actually does. * Fixed privilege check for CREATE TABLE .. LIKE .. ; It now requires SELECT privileges on the table. * Fixed privilege check for SHOW CREATE TABLE ..; It now requires any privilege on the table level. sql/sql_plugin.cc: * check_table_access has new signature sql/sql_prepare.cc: * check_table_access has new signature sql/sql_show.cc: * check_table_access has new signature sql/sql_trigger.cc: * check_table_access has new signature sql/sql_update.cc: * check grant has new signature sql/sql_view.cc: * check_table_access has new signature
