Bug#18790730 - CROSS-DATABASE FOREIGN KEY WITHOUT PERMISSIONS CHECK. Analysis: ---------- Issue here is, while creating or altering the InnoDB table, if the foreign key defined on the table references a parent table on which the user has no access privileges then the table is created without reporting any error. Currently the privilege level REFERENCES_ACL is unused and is not used for access evaluation while creating the table with a foreign key constraint or adding the foreign key constraint to a table. But when no privileges are granted to user then also access evaluation on parent table is ignored. Fix: --------- For DMLs, irrelevant of the fact, support does not want any changes to avoid permission checks on every operation. So, as a fix, added a function "check_fk_parent_table_access" to check whether any of the SELECT_ACL, INSERT_ACL, UDPATE_ACL, DELETE_ACL or REFERENCE_ACL privileges are granted for user at table level. If none of them is granted then error is reported. This function is called during the table creation and alter operation.

Changing field::field_name and Item::name to LEX_CSTRING Benefits of this patch: - Removed a lot of calls to strlen(), especially for field_string - Strings generated by parser are now const strings, less chance of accidently changing a string - Removed a lot of calls with LEX_STRING as parameter (changed to pointer) - More uniform code - Item::name_length was not kept up to date. Now fixed - Several bugs found and fixed (Access to null pointers, access of freed memory, wrong arguments to printf like functions) - Removed a lot of casts from (const char*) to (char*) Changes: - This caused some ABI changes - lex_string_set now uses LEX_CSTRING - Some fucntions are now taking const char* instead of char* - Create_field::change and after changed to LEX_CSTRING - handler::connect_string, comment and engine_name() changed to LEX_CSTRING - Checked printf() related calls to find bugs. Found and fixed several errors in old code. - A lot of changes from LEX_STRING to LEX_CSTRING, especially related to parsing and events. - Some changes from LEX_STRING and LEX_STRING & to LEX_CSTRING* - Some changes for char* to const char* - Added printf argument checking for my_snprintf() - Introduced null_clex_str, star_clex_string, temp_lex_str to simplify code - Added item_empty_name and item_used_name to be able to distingush between items that was given an empty name and items that was not given a name This is used in sql_yacc.yy to know when to give an item a name. - select table_name."*' is not anymore same as table_name.* - removed not used function Item::rename() - Added comparision of item->name_length before some calls to my_strcasecmp() to speed up comparison - Moved Item_sp_variable::make_field() from item.h to item.cc - Some minimal code changes to avoid copying to const char * - Fixed wrong error message in wsrep_mysql_parse() - Fixed wrong code in find_field_in_natural_join() where real_item() was set when it shouldn't - ER_ERROR_ON_RENAME was used with extra arguments. - Removed some (wrong) ER_OUTOFMEMORY, as alloc_root will already give the error.

BUG#50479 DDL stmt on row-only/stmt-only tables generate spurious binlog_format errors In the fix of BUG#39934 in 5.1-rep+3, errors are generated when binlog_format=row and a statement modifies a table restricted to statement-logging (ER_BINLOG_ROW_MODE_AND_STMT_ENGINE); or if binlog_format=statement and a statement modifies a table restricted to row-logging (ER_BINLOG_STMT_MODE_AND_ROW_ENGINE). However, some DDL statements that lock tables (e.g. ALTER TABLE, CREATE INDEX and CREATE TRIGGER) were causing spurious errors, although no row might be inserted into the binary log. To fix the problem, we tagged statements that may generate rows into the binary log and thence the warning messages are only printed out when the appropriate conditions hold and rows might be changed. sql/log_event.cc: Reorganized the Query_log_event's constructor based on the CF_CAN_GENERATE_ROW_EVENTS flag and as such any statement that has the associated flag should go through a cache before being written to the binary log. sql/share/errmsg-utf8.txt: Improved the error message ER_BINLOG_UNSAFE_MIXED_STATEMENT according to Paul's suggestion. sql/sql_class.cc: Created a hook to be used by innodb that checks if a statement may write rows to the binary log. In other words, if it has the CF_CAN_GENERATE_ROW_EVENTS flag associated. sql/sql_class.h: Defined the CF_CAN_GENERATE_ROW_EVENTS flag. sql/sql_parse.cc: Updated the sql_command_flags and added a function to check the CF_CAN_GENERATE_ROW_EVENTS. sql/sql_parse.h: Added a function to check the CF_CAN_GENERATE_ROW_EVENTS. storage/innobase/handler/ha_innodb.cc: Added a call to the hook thd_generates_rows(). storage/innobase/handler/ha_innodb.h: Defined an external reference to the hook thd_generates_rows().

Changing field::field_name and Item::name to LEX_CSTRING Benefits of this patch: - Removed a lot of calls to strlen(), especially for field_string - Strings generated by parser are now const strings, less chance of accidently changing a string - Removed a lot of calls with LEX_STRING as parameter (changed to pointer) - More uniform code - Item::name_length was not kept up to date. Now fixed - Several bugs found and fixed (Access to null pointers, access of freed memory, wrong arguments to printf like functions) - Removed a lot of casts from (const char*) to (char*) Changes: - This caused some ABI changes - lex_string_set now uses LEX_CSTRING - Some fucntions are now taking const char* instead of char* - Create_field::change and after changed to LEX_CSTRING - handler::connect_string, comment and engine_name() changed to LEX_CSTRING - Checked printf() related calls to find bugs. Found and fixed several errors in old code. - A lot of changes from LEX_STRING to LEX_CSTRING, especially related to parsing and events. - Some changes from LEX_STRING and LEX_STRING & to LEX_CSTRING* - Some changes for char* to const char* - Added printf argument checking for my_snprintf() - Introduced null_clex_str, star_clex_string, temp_lex_str to simplify code - Added item_empty_name and item_used_name to be able to distingush between items that was given an empty name and items that was not given a name This is used in sql_yacc.yy to know when to give an item a name. - select table_name."*' is not anymore same as table_name.* - removed not used function Item::rename() - Added comparision of item->name_length before some calls to my_strcasecmp() to speed up comparison - Moved Item_sp_variable::make_field() from item.h to item.cc - Some minimal code changes to avoid copying to const char * - Fixed wrong error message in wsrep_mysql_parse() - Fixed wrong code in find_field_in_natural_join() where real_item() was set when it shouldn't - ER_ERROR_ON_RENAME was used with extra arguments. - Removed some (wrong) ER_OUTOFMEMORY, as alloc_root will already give the error. TODO: - Check possible unsafe casts in plugin/auth_examples/qa_auth_interface.c - Change code to not modify LEX_CSTRING for database name (as part of lower_case_table_names)
