Kailasnath Nagarkar	322afb2c0a	Bug #19984392 : MEDIUMINT: STACK BUFFER OVERFLOW IN PROTOCOL_TEXT::STORE_LONG ISSUE: Queries with mediumint as column when operated with long long type of data results in buffer overflow in store_long function. The merging rule specified for (MYSQL_TYPE_LONGLONG MYSQL_TYPE_INT24) is MYSQL_TYPE_LONG. Due to this store_long function was getting called which resulted in buffer overflow. SOLUTION: The correct merging rule for (MYSQL_TYPE_LONGLONG, MYSQL_TYPE_INT24) should be MYSQL_TYPE_LONGLONG. So, instead of function store_long, function store_longlong is called which correctly handles the type MYSQL_TYPE_LONGLONG. External Bug #23645238 is a duplicate of this issue.	9 years ago
Sreeharsha Ramanavarapu	8bb95e9a97	Bug #24380263 : INCORRECT BEHAVIOR WITH PARAMETER AND DERIVED TABLE IN JOIN ISSUE: ------ This problem occurs under the following conditions: 1) A parameter is used in the select-list of a derived table. 2) The derived table is part of a JOIN. SOLUTION: --------- When a derived table is materialized, a temporary table is created. This temporary table creates a field each for the items in the select-list of the derived table. This set of fields is later used to setup the join. Currently no field is created in the temporary table if a parameter is used in the select-list. Create a field for the parameter. By default Item_param's result type in a prepared statement is set to STRING_RESULT. This can change during the execute phase depending on the user variable. But since the execute phase creates its own temporary table, it will be handled separately. This is a backport of the fix for BUG#22392374.	9 years ago

Sergei Petrunia	15ef38d2ea	MDEV-10228: Delete missing rows with OR conditions Fix get_quick_keys(): When building range tree from a condition in form keypart1=const AND (keypart2 < 0 OR keypart2>=0) the SEL_ARG for keypart2 represents an interval (-inf, +inf). However, the logic that sets UNIQUE_RANGE flag fails to recognize this, and sets UNIQUE_RANGE flag if (keypart1, keypart2) covered a unique key. As a result, range access executor assumes the interval can have at most one row and only reads the first row from it.	9 years ago
Neha Kumari	a63a250d40	BUG#23509275 :DBUG_PRINT in THD::decide_logging_format prints incorrectly, access out-of-bound Problem: In debug builds, there is a chance that an out-of-bounds read is performed when tables are locked in LTM_PRELOCKED_UNDER_LOCK_TABLES mode. It can happen because the debug code uses enum values as index for an array of mode descriptions, but it only takes into consideration 3 out of 4 of the enum values. Fix: This patch fixes it by implementing a getter for the enum which returns a string representation of the enum, effectively removing the out-of-bounds read. Moreover, it also fixes the lock mode descriptions that would be print out in debug builds.	9 years ago
Thayumanavar S	2674cf91c5	BUG#23703568 - IS CLIENT LIBRARY SUPPOSED TO RETRY EINTR INDEFINITELY OR NOT Commit#ebd24626ca38e7fa1e3da2acdcf88540be70fabe obsoleted the THREAD and THREAD_SAFE_CLIENT preprocessor symbols. This is not removed in the sql/net_serv.cc thereby the code that retries on EINTR became dead code. Remove the THREAD_SAFE_CLIENT preprocessor directive form sql/net_serv.cc. Also check errno for EINTR only if there is an error in preceding read call.	9 years ago
Arun Kuruvila	fd31eea949	Bug #23295288 : HANDLE_FATAL_SIGNAL (SIG=11) IN GET_SERVER_FROM_TABLE_TO_CACHE Description:- Server received SIG11 in the function, "get_server_from_table_to_cache()". Analysis:- Defining a server with a blank name is not handled properly. Fix:- Modified "get_server_from_table_to_cache()" to take care of blank server name.	9 years ago
Sreeharsha Ramanavarapu	ac460e584d	Bug #23280699 : MYSQLD GOT SIGNAL 11 IN IS_NULL ON SELECT FROM I_S Issue: ------ There is a difference in the field type created when the following DDLs are used: 1) CREATE TABLE t0 AS SELECT NULL; 2) CREATE TABLE t0 AS SELECT GREATEST(NULL,NULL); The first statement creates field of type Field_string and the second one creates a field of type Field_null. This creates a problem when the query mentioned in this bug is used. Since the null_ptr is calculated differently for Field_null. Solution: --------- When there is a function returning null in the select list as mentioned above, the field should be of type Field_string. This was fixed in 5.6+ as part of Bug#14021323. This is a backport to mysql-5.5. An incorrect comment in innodb_bug54044.test has been corrected in all versions.	9 years ago

Sergei Golubchik	e81455bb16	MDEV-7973 bigint fail with gcc 5.0 -LONGLONG_MIN is the undefined behavior in C. longlong2decimal() used to do this: int longlong2decimal(longlong from, decimal_t to) { if ((to->sign= from < 0)) return ull2dec(-from, to); return ull2dec(from, to); and later in ull2dec() (DIG_BASE is 1000000000): static int ull2dec(ulonglong from, decimal_t to) { for (intg1=1; from >= DIG_BASE; intg1++, from/=DIG_BASE) {} this breaks in gcc-5 at -O3. Here ull2dec is inlined into longlong2decimal. And gcc-5 believes that 'from' in the inlined ull2dec is always a positive integer (indeed, if it was negative, then -from was used instead). So gcc-5 uses signed comparison with DIG_BASE. Fix: make a special case for LONGLONG_MIN, don't negate it	11 years ago

Kailasnath Nagarkar	07a33cdcef	Bug #23296299 : HANDLE_FATAL_SIGNAL (SIG=11) IN MY_TOSORT_UTF32 This patch is specific for mysql-5.5 ISSUE: When a charater that is larger than possible to handle is passed to function my_tosort_utf32(), it results in segmentation fault. In the scenario mentioned in the bug AES_ENCRYPT function is used which returns large value. This value is further passed to my_tosort_utf32 function. This causes to cross array bound for array uni_plane, resulting in segment violation. SOLUTION: This issue has got addressed in 5.6 onward releases through worklog 2673. The fix is similar backport of that. Check for maximum character before accessing the array uni_plane. In addition to function my_tosort_utf32, the same potential problem is also present in functions my_tolower_utf16, my_toupper_utf16, my_tosort_utf16, my_tolower_utf32, my_toupper_utf32, my_tosort_unicode, my_tolower_utf8mb4 and my_toupper_utf8mb4. Fixed these functions as well.	10 years ago
Christopher Powers	6986645c79	Bug#14111584 PB2: PERFSCHEMA.AGGREGATE FAILS ON PB2 SPORADICALLY Permanently removed test case perfschema.aggregate.

This test needs to be redesigned to accommodate such variances.	10 years ago

Sergey Vojtovich	7f38a070ba	MDEV-10043 - main.events_restart fails sporadically in buildbot (crashes upon shutdown) There was race condition between shutdown thread and event worker threads. Shutdown thread waits for thread_count to become 0 in close_connections(). It may happen so that event worker thread was started but didn't increment thread_count by this time. In this case shutdown thread may miss wait for this working thread and continue deinitialization. Worker thread in turn may continue execution and crash on deinitialized data. Fixed by incrementing thread_count before thread is actually created like it is done for connection threads. Also let event scheduler not to inc/dec running threads counter for symmetry with other "service" threads.	10 years ago
Thayumanavar S	9f7288e2e0	BUG#23080148 - BACKPORT BUG 14653594 AND BUG 20683959 TO MYSQL-5.5 The bug asks for a backport of bug#1463594 and bug#20682959. This is required because of the fact that if replication is enabled, master transaction can commit whereas slave can't commit due to not exact 'enviroment'. This manifestation is seen in bug#22024200.	10 years ago

Shishir Jaiswal	957aefdc8f	Bug#23498283 - BUFFER OVERFLOW 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.	10 years ago
