Georgi Kodinov	addd0a3e67	On behalf of Kristofer : Bug#53417 my_getwd() makes assumptions on the buffer sizes which not always hold true The mysys library contains many functions for rewriting file paths. Most of these functions makes implicit assumptions on the buffer sizes they write to. If a path is put in my_realpath() it will propagate to my_getwd() which assumes that the buffer holding the path name is greater than 2. This is not true in cases. In the special case where a VARBIN_ITEM is passed as argument to the LOAD_FILE function this can lead to a crash. This patch fixes the issue by introduce more safe guards agaist buffer overruns.	16 years ago
Jimmy Yang	6bc1a96b31	Port fix for 53165 to InnoDB 5.1 plugin. The change buffering options are different in 5.1 comparing to that of 5.5, so a hand port is necessary to avoid wrong default option to be set by a simple branch merge.	16 years ago

Andrei Elkin	efcc90b6eb	Bug #50942 mix_innodb_myisam_side_effects.test is not deterministic The test was used to fail because of UPDATE t3,t4 SET t3.a=t4.a + bug27417(1); did not prescribe the order of two row operations implied by the update. Fixed with forcing the order with adding a where condition w/o affecting the former bug fixes logics. mysql-test/extra/binlog_tests/mix_innodb_myisam_side_effects.test: implemented the bug page suggestion to make a test deterministic. mysql-test/suite/binlog/r/binlog_row_mix_innodb_myisam.result: results are updated and (!) corrected. mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result: results are updated	16 years ago
Georgi Kodinov	71b453fa06	Bug #53371 : COM_FIELD_LIST can be abused to bypass table level grants. This is the 5.1 merge and extension of the fix. The server was happily accepting paths in table name in all places a table name is accepted (e.g. a SELECT). This allowed all users that have some privilege over some database to read all tables in all databases in all mysql server instances that the server file system has access to. Fixed by : 1. making sure no path elements are allowed in quoted table name when constructing the path (note that the path symbols are still valid in table names when they're properly escaped by the server). 2. checking the #mysql50# prefixed names the same way they're checked for path elements in mysql-5.0.	16 years ago

Kristofer Pettersson	5dd5d70506	Bug#50373 --secure-file-priv="" Iterative patch improvement. Previously committed patch caused wrong result on Windows. The previous patch also broke secure_file_priv for symlinks since not all file paths which must be compared against this variable are normalized using the same norm. The server variable opt_secure_file_priv wasn't normalized properly and caused the operations LOAD DATA INFILE .. INTO TABLE .. and SELECT load_file(..) to do different interpretations of the --secure-file-priv option. The patch moves code to the server initialization routines so that the path always is normalized once and only once. It was also intended that setting the option to an empty string should be equal to lifting all previously set restrictions. This is also fixed by this patch. mysql-test/r/loaddata.result: * Removed test code which will currently break the much used --mem feature of mtr. mysql-test/t/loaddata.test: * Removed test code which will currently break the much used --mem feature of mtr. sql/item_strfunc.cc: * Replaced string comparing code on opt_secure_file_priv with an interface which guarantees that both file paths are normalized using the same norm on all platforms. sql/mysql_priv.h: * Added signature for is_secure_file_path() sql/mysqld.cc: * New function for checking if a path compatible with the secure path restriction. * Added initialization of the opt_secure_file_priv variable. sql/sql_class.cc: * Replaced string comparing code on opt_secure_file_priv with an interface which guarantees that both file paths are normalized using the same norm on all platforms. sql/sql_load.cc: * Replaced string comparing code on opt_secure_file_priv with an interface which guarantees that both file paths are normalized using the same norm on all platforms.	16 years ago
Georgi Kodinov	f63608ea97	Bug #53371 : COM_FIELD_LIST can be abused to bypass table level grants. The server was not checking the supplied to COM_FIELD_LIST table name for validity and compliance to acceptable table names standards.

Alexey Kopytov	97374a1184	Bug #48419 : another explain crash.. WHERE predicates containing references to empty tables in a subquery were handled incorrectly by the optimizer when executing EXPLAIN. As a result, the optimizer could try to evaluate such predicates rather than just stop with "Impossible WHERE noticed after reading const tables" as it would do in a non-subquery case. This led to valgrind errors and crashes. Fixed the code checking the above condition so that subqueries are not excluded and hence are handled in the same way as top level SELECTs. mysql-test/r/explain.result: Added a test case for bug #48419. mysql-test/r/ps.result: Updated test results to take the new (and more correct) "Extra" comments in execution plans. mysql-test/t/explain.test: Added a test case for bug #48419. sql/sql_select.cc: There is no point in excluding subqueries from checking for identically false WHERE conditions.	16 years ago

Davi Arnaut	54705ab176	Bug#50974: Server keeps receiving big (> max_allowed_packet) packets indefinitely. The server could be tricked to read packets indefinitely if it received a packet larger than the maximum size of one packet. This problem is aggravated by the fact that it can be triggered before authentication. The solution is to no skip big packets for non-authenticated sessions. If a big packet is sent before a session is authen- ticated, a error is returned and the connection is closed. include/mysql_com.h: Add skip flag. Only used in server builds. sql/net_serv.cc: Control whether big packets can be skipped.	16 years ago

Alexey Kopytov	6d43510a42	Backport of the fix for bug #50335 to 5.0. The problem was in an incorrect debug assertion. The expression used in the failing assertion states that when finding references matching ORDER BY expressions, there can be only one reference to a single table. But that does not make any sense, all test cases for this bug are valid examples with multiple identical WHERE expressions referencing the same table which are also present in the ORDER BY list. Fixed by removing the failing assertion. We also have to take care of the 'found' counter so that we count multiple references only once. We rely on this fact later in eq_ref_table(). mysql-test/r/join.result: Added a test case for bug #50335. mysql-test/t/join.test: Added a test case for bug #50335. sql/sql_select.cc: Removing the assertion in eq_ref_table() as it does not make any sense.
