| | | | | | | | | | | | signed integer overflow: x * y cannot be represented in type 'long long int' (on optimized builds). Avoid integer overflow, do the check before the calculation.

| | | | | | | | | | | | | | | | | | | | my_copy_fix_mb() passed MIN(src_length,dst_length) to my_append_fix_badly_formed_tail(). It could break a multi-byte character in the middle, which put the question mark to the destination. Fixing the code to pass the true src_length to my_append_fix_badly_formed_tail().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in row_merge_fts_doc_tokenize, stack smashing strmake() puts one extra 0x00 byte at the end of the string. The code in my_strnxfrm_tis620[_nopad] did not take this into account, so in the reported scenario the 0x00 byte was put outside of a stack variable, which made ASAN crash. This problem is already fixed in in MySQL: commit 19bd66fe43c41f0bde5f36bc6b455a46693069fb Author: bin.x.su@oracle.com <> Date: Fri Apr 4 11:35:27 2014 +0800 But the fix does not seem to be correct, as it breaks when finds a zero byte in the source string. Using memcpy() instead of strmake(). - Unlike strmake(), memcpy() it does not write beyond the destination size passed. - Unlike the MySQL fix, memcpy() does not break on the first 0x00 byte found in the source string.

| * MDEV-22387: Do not violate __attribute__((nonnull))Marko Mäkelä2020-11-022-4/+6
| | | | | | | | | | | | | | | | | | | | | | 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-23941: strings/json_lib.c:893:12: style: Suspicious conditionVicențiu Ciorbaru2020-10-231-1/+1
| | | | | | | | | | | | | | | | | | | | The characters parsed are always ascii characters, hence one byte. This means that the code did not have "incorrect" logic because the boolean condition, if true, would also evaluate to the value of 1. The condition however is semantically wrong, assuming a length is equal to the condition outcome. Change paranthesis to make it also read according to the intent.

| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | For some reason, GCC emits more -Wmaybe-uninitialized warnings when using the flag -Og than when using -O2. Many of the warnings look genuine.

| * | MDEV-20377: Make WITH_MSAN more usableMarko Mäkelä2020-07-011-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MemorySanitizer (clang -fsanitize=memory) requires that all code be compiled with instrumentation enabled. The only exception is the C runtime library. Failure to use instrumented libraries will cause bogus messages about memory being uninitialized. In WITH_MSAN builds, we must avoid calling getservbyname(), because even though it is a standard library function, it is not instrumented, not even in clang 10. Note: Before MariaDB Server 10.5, ./mtr will typically fail due to the old PCRE library, which was updated in MDEV-14024. The following cmake options were tested on 10.5 in commit 94d0bb4dbeb28a94d1f87fdd55f4297ff3df0157: cmake \ -DCMAKE_C_FLAGS='-march=native -O2' \ -DCMAKE_CXX_FLAGS='-stdlib=libc++ -march=native -O2' \ -DWITH_EMBEDDED_SERVER=OFF -DWITH_UNIT_TESTS=OFF -DCMAKE_BUILD_TYPE=Debug \ -DWITH_INNODB_{BZIP2,LZ4,LZMA,LZO,SNAPPY}=OFF \ -DPLUGIN_{ARCHIVE,TOKUDB,MROONGA,OQGRAPH,ROCKSDB,CONNECT,SPIDER}=NO \ -DWITH_SAFEMALLOC=OFF \ -DWITH_{ZLIB,SSL,PCRE}=bundled \ -DHAVE_LIBAIO_H=0 \ -DWITH_MSAN=ON MEM_MAKE_DEFINED(): An alias for VALGRIND_MAKE_MEM_DEFINED() and __msan_unpoison(). MEM_GET_VBITS(), MEM_SET_VBITS(): Aliases for VALGRIND_GET_VBITS(), VALGRIND_SET_VBITS(), __msan_copy_shadow(). InnoDB: Replace the UNIV_MEM_ macros with corresponding MEM_ macros. ut_crc32_8_hw(), ut_crc32_64_low_hw(): Use the compiler built-in functions instead of inline assembler when building WITH_MSAN. This will require at least -msse4.2 when building for IA-32 or AMD64. The inline assembler would not be instrumented, and would thus cause bogus failures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replacing the slow loop in my_hash_sort_utf8mbX() to the fast skip_trailing_spaces(), which consumes 8 bytes in one iteration, and is around 8 times faster on long data. Also, renaming: - my_hash_sort_utf8() to my_hash_sort_utf8mb3() - my_hash_sort_utf8_nopad() to my_hash_sort_utf8mb3_nopad() to merge to 10.5 easier (automatically?).
