| * Added detection of memory overwrite with multi_mallocbb-10.5-montyMonty2023-02-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch also fixes some bugs detected by valgrind after this patch: - Not enough copy_func elements was allocated by Create_tmp_table() which causes an memory overwrite in Create_tmp_table::add_fields() I added an ASSERT() to be able to detect this also without valgrind. The bug was that TMP_TABLE_PARAM::copy_fields was not correctly set when calling create_tmp_table(). - Aria::empty_bits is not allocated if there is no varchar/char/blob fields in the table. Fixed code to take this into account. This cannot cause any issues as this is just a memory access into other Aria memory and the content of the memory would not be used. - Aria::last_key_buff was not allocated big enough. This may have caused issues with rtrees and ma_extra(HA_EXTRA_REMEMBER_POS) as they would use the same memory area. - Aria and MyISAM didn't take extended key parts into account, which caused problems when copying rec_per_key from engine to sql level. - Mark asan builds with 'asan' in version strihng to detect these in not_valgrind_build.inc. This is needed to not have main.sp-no-valgrind fail with asan.

| * Fix synopses in mysys APIsAlexander Kuleshov2023-01-061-1/+1
| | | | | | | | | | | | Since 7c58e97 the PSI_memory_key was added to some routines in the mysys/. This commit fixes synopses of functions that were updated with the PSI_memory_key parameter.
* | Added support to MEM_ROOT for write protected memoryMonty2021-07-181-75/+193
|/ | | | | | | | | | | | | | | | | | | | | | | This is useful for thing like Item_true and Item_false that we allocated and initalize once and want to ensure that nothing can change them Main changes: - Memory protection is achived by allocating memory with mmap() and protect it from write with mprotect() - init_alloc_root(...,MY_ROOT_USE_MPROTECT) will create a memroot that one can later use with protect_root() to turn it read only or turn it back to read-write. All allocations to this memroot is done with mmap() to ensure page alligned allocations. - alloc_root() code was rearranged to combine normal and valgrind code. - init_alloc_root() now changes block size to be power of 2's, to get less memory fragmentation. - Changed MEM_ROOT structure to make it smaller. Also renamed MEM_ROOT m_psi_key to psi_key. - Moved MY_THREAD_SPECIFIC marker in MEM_ROOT from block size (old hack) to flags. - Added global variable my_system_page_size. This is initialized at startup.
* MDEV-22929 fixup: root_name() clash with clang++ <fstream>Marko Mäkelä2020-12-031-4/+3
| | | | | | | | | | | | The clang++ -stdlib=libc++ header file <fstream> depends on <filesystem> that defines a member function path::root_name(), which conflicts with the rather unused #define root_name() that had been introduced in commit 7c58e97bf6f80a251046c5b3e7bce826fe058bd6. Because an instrumented -stdlib=libc++ (rather than the default -stdlib=libstdc++) is easier to build for a working -fsanitize=memory (cmake -DWITH_MSAN=ON), let us remove the conflicting #define for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows up commit commit 94a520ddbe39ae97de1135d98699cf2674e6b77e and commit 7c5519c12d46ead947d341cbdcbb6fbbe4d4fe1b. After these changes, the default test suites on a cmake -DWITH_UBSAN=ON build no longer fail due to passing null pointers as parameters that are declared to never be null, but plenty of other runtime errors remain.

| | | * MDEV-22387: Do not pass null pointer to some memcpy()Marko Mäkelä2020-09-031-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Passing a null pointer to a nonnull argument is not only undefined behaviour, but it also grants the compiler the permission to optimize away further checks whether the pointer is null. GCC -O2 at least starting with version 8 may do that, potentially causing SIGSEGV. These problems were caught in a WITH_UBSAN=ON build with the Bug#7024 test in main.view.

The primary use of MEM_UNDEFINED is for declaring memory uninitialized in Valgrind or MemorySanitizer. We do not want MEM_UNDEFINED to have the unwanted side effect that AddressSanitizer would no longer be able to complain about accessing unallocated memory. MEM_UNDEFINED(): Define as no-op for AddressSanitizer. MEM_MAKE_ADDRESSABLE(): Define as MEM_UNDEFINED() or ASAN_UNPOISON_MEMORY_REGION(). MEM_CHECK_ADDRESSABLE(): Wrap also __asan_region_is_poisoned().

On the right of every chunk there will be either 1-7 trailing poisoned bytes, or next chunk's redzone, or poisoned non allocated memory or redzone of a malloc()ed buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TRASH was mapped to TRASH_FREE and was supposed to be used for memory that should not be accessed anymore, while TRASH_ALLOC() is to be used for uninitialized but to-be-used memory. But sometimes TRASH() was used in the latter sense. Remove TRASH() macro, always use explicit TRASH_ALLOC() or TRASH_FREE().

* | | | Reducing memory when using information schemaMonty2017-11-021-1/+21
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The background is that one user had a lot of views and using some complex queries on information schema temporary memory of more than 2G was used. - Added new element 'total_alloc' to MEM_ROOT for easier debugging. - Added MAX_MEMORY_USED to information_schema.processlist. - Added new status variable "Memory_used_initial" that shows how much MariaDB uses at startup. This gives the base value for "Memory_used". - Reuse memory continuously for information schema queries instead of only freeing memory at query end. Other things - Removed some not needed set_notnull() calls for not null columns.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Addendum: * Before calling THD::init_for_queries(), flip the current_thd to wsrep thread so that memory gets allocated for the right THD. * Use wsrep_creating_startup_threads instead of plugins_are_initialized as the condition for the execution of THD::init_for_queries() within start_wsrep_THD(), as use of latter could still leave some room for race.

The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC. Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc(). There are plenty of new asserts to ensure that for a debug server the counting is correct. Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS. - The later is there mainly to show how query is progressing. The following changes in interfaces was needed to get this to work: - init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root() - my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - Added flag for hash_init() so that one can mark hash table to be thread specific. - Added flags to init_tree() so that one can mark tree to be thread specific. - Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG. - Added flag to Warning_info::Warning_info() if the structure should be fully initialized. - String elements can now be marked as thread specific. - Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC. - Changed type of myf from int to ulong, as this is always a set of bit flags. Other things: - Removed calls to net_end() and thd->cleanup() as these are now done in ~THD() - We now also show EXAMINED_ROWS in SHOW PROCESSLIST - Added new variable 'memory_used' - Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory. - Removed calls to the obsoleted function init_dynamic_array() - Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...) client/completion_hash.cc: Updated call to init_alloc_root() client/mysql.cc: Updated call to init_alloc_root() client/mysqlbinlog.cc: init_dynamic_array() -> my_init_dynamic_array() Updated call to init_alloc_root() client/mysqlcheck.c: Updated call to my_init_dynamic_array() client/mysqldump.c: Updated call to init_alloc_root() client/mysqltest.cc: Updated call to init_alloc_root() Updated call to my_init_dynamic_array() Fixed compiler warnings extra/comp_err.c: Updated call to my_init_dynamic_array() extra/resolve_stack_dump.c: Updated call to my_init_dynamic_array() include/hash.h: Added HASH_THREAD_SPECIFIC include/heap.h: Added flag is internal temporary table. include/my_dir.h: Safety fix: Ensure that MY_DONT_SORT and MY_WANT_STAT don't interfer with other mysys flags include/my_global.h: Changed type of myf from int to ulong, as this is always a set of bit flags. include/my_sys.h: Added MY_THREAD_SPECIFIC and MY_THREAD_MOVE Added malloc_flags to DYNAMIC_ARRAY Added extra mysys flag argument to my_init_dynamic_array() Removed deprecated functions init_dynamic_array() and my_init_dynamic_array.._ci Updated paramaters for init_alloc_root() include/my_tree.h: Added my_flags to allow one to use MY_THREAD_SPECIFIC with hash tables.
