impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views.

We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. sql/sp.h: sp_cache_routines_and_add_tables_for_view()/for_triggers(): To be able to determine correctly uppermost view which uses this view/table with trigger we have to pass pointer to TABLE_LIST object instead of pointer to view's LEX or to Table_triggers_list object. sql/sp_head.cc: sp_head::add_used_tables_to_table_list(): Added new argument which allows to mark tables which are added to table list for prelocking as belonging to view (this allows properly hide names of tables which are used in routines used by views). sql/sp_head.h: sp_head::add_used_tables_to_table_list(): Added new argument which allows to mark tables which are added to table list for prelocking as belonging to view (this allows properly hide names of tables which are used in routines used by views). sql/sql_base.cc: open_tables(): sp_cache_routines_and_add_tables_for_view()/for_triggers() now accept pointer to table list element as last argument, this allows them to determine correctly uppermost view which uses this view/table with trigger. sql/sql_trigger.h: Table_triggers_list: sp_cache_routines_and_add_tables_for_triggers() now accept pointer to table list element as last argument, this allows to determine correctly uppermost view which uses this table with trigger. |
