| * Bug#23498283 - BUFFER OVERFLOWShishir Jaiswal2016-06-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DESCRIPTION =========== Buffer overflow is reported in Regex library. This can be triggered when the data corresponding to argv[1] is >= 512 bytes resutling in abnormal behaviour. ANALYSIS ======== Its a straight forward case of SEGFAULT where the target buffer is smaller than the source string to be copied. A simple pre-copy validation should do. FIX === A check is added before doing strcpy() to ensure that the target buffer is big enough to hold the to-be copied data. If the check fails, the program aborts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DESCRIPTION =========== Buffer overflow is reported in a lot of code sections spanning across server, client programs, Regex libraries etc. If not handled appropriately, they can cause abnormal behaviour. ANALYSIS ======== The reported casea are the ones which are likely to result in SEGFAULT, MEMORY LEAK etc. FIX === - sprintf() has been replaced by my_snprintf() to avoid buffer overflow. - my_free() is done after checking if the pointer isn't NULL already and setting it to NULL thereafter at few places. - Buffer is ensured to be large enough to hold the data. - 'unsigned int' (aka 'uint') is replaced with 'size_t' to avoid wraparound. - Memory is freed (if not done so) after its alloced and used. - Inserted assert() for size check in InnoDb memcached code (from 5.6 onwards) - Other minor changes

| * Bug#20642505: HENRY SPENCER REGULAR EXPRESSIONS (REGEX) LIBRARYTatiana Azundris Nuernberg2015-05-181-1/+23
| | | | | | | | | | | | | | | | | | | | The MySQL server uses Henry Spencer's library for regular expressions to support the REGEXP/RLIKE string operator. This changeset adapts a recent fix from the upstream for better 32-bit compatiblity. (Note that we cannot simply use the current upstream version as a drop-in replacement for the version used by the server as the latter has been extended to understand MySQL charsets etc.)

| * | | WL#5665: Removal of the autotools-based build systemDavi Arnaut2010-11-201-33/+0

In order to support tools that need to extract the server version, a new file that (only) contains the server version, called VERSION, is introduced. The file contents are human and machine-readable. The format is: MYSQL_VERSION_MAJOR=5 MYSQL_VERSION_MINOR=5 MYSQL_VERSION_PATCH=8 MYSQL_VERSION_EXTRA=-rc The CMake based version extraction in cmake/mysql_version.cmake is changed to extract the version from this file. The configure to CMake wrapper is retained for backwards compatibility and to support the BUILD/ scripts. Also, a new a makefile target show-dist-name that prints the server version is introduced.

One major source of warnings was the in-house function my_bcmp which (unconventionally) took pointers to unsigned characters as the byte sequences to be compared. Since my_bcmp and bcmp are deprecated functions whose only difference with memcmp is the return value, every use of the function is replaced with memcmp as the special return value wasn't actually being used by any caller. There were also various other warnings, mostly due to type mismatches, missing return values, missing prototypes, dead code (unreachable) and ignored return values.

Instead, put them into top level CMakeLists.txt, but disable on Windows, because a) SAFEMALLOC does not add any functionality that is not already present in Debug C runtime ( and 2 safe malloc one on top of the other only unnecessarily slows down the server) b)SAFE_MUTEX does not work on Windows and have been explicitely disabled on Windows with #undef previously.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with gcc 4.3.2 This patch fixes a number of GCC warnings about variables used before initialized. A new macro UNINIT_VAR() is introduced for use in the variable declaration, and LINT_INIT() usage will be gradually deprecated. (A workaround is used for g++, pending a patch for a g++ bug.) GCC warnings for unused results (attribute warn_unused_result) for a number of system calls (present at least in later Ubuntus, where the usual void cast trick doesn't work) are also fixed.

| | | | | | | | | | | | | | | | | | | | | | | | value" error even though the value was correct): a C function in my_getopt.c was taking bool* in parameter and was called from C++ sql_plugin.cc, but on some Mac OS X sizeof(bool) is 1 in C and 4 in C++, giving funny mismatches.

Instead set the output file name. - Created work around for bug in CMake 2.4.6 and output names, to set the "mysqld<suffix>.pdb" name to the same base name. - Set the correct manifest "name" (patch by iggy)

To fix this, the (previous) files in 5.1 now are deleted ("bk rm"), and the previously deleted files depending on 5.0 are now moved to the respective source directories ("bk mv"). The current 5.1 contents is restored in these files. If you need the previous history of the 5.1 files ("bk revtool"), access those in "BitKeeper/deleted". Contrary to the original plan, I did not introduce the name "CMakeLists.historic" - mostly in order not to clutter the source tree. This fixes bug#29982.

Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c
