      BUG#49124 Security issue with /*!-versioned */ SQL statements on Slave · 2124538d
      unknown authored
      /*![:version:] Query Code */, where [:version:] is a sequence of 5 
      digits representing the mysql server version(e.g /*!50200 ... */),
      is a special comment that the query in it can be executed on those 
      servers whose versions are larger than the version appearing in the 
      comment. It leads to a security issue when slave's version is larger 
      than master's. A malicious user can improve his privileges on slaves. 
      Because slave SQL thread is running with SUPER privileges, so it can
      execute queries that he/she does not have privileges on master.
      
      This bug is fixed with the logic below: 
      - To replace '!' with ' ' in the magic comments which are not applied on
        master. So they become common comments and will not be applied on slave.
      
      - Example:
        'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
        will be binlogged as
        'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/
      
      mysql-test/suite/rpl/t/rpl_conditional_comments.test:
        Test the patch for this bug.
      sql/mysql_priv.h:
        Rename inBuf as rawBuf and remove the const limitation.
      sql/sql_lex.cc:
        To replace '!' with ' ' in the magic comments which are not applied on
        master.
      sql/sql_lex.h:
        Remove the const limitation on parameter buff, as it can be modified in the function since
        this patch.
        Add member function yyUnput for Lex_input_stream. It set a character back the query buff.
      sql/sql_parse.cc:
        Rename inBuf as rawBuf and remove the const limitation.
      sql/sql_partition.cc:
        Remove the const limitation on parameter part_buff, as it can be modified in the function since
        this patch.
      sql/sql_partition.h:
        Remove the const limitation on parameter part_buff, as it can be modified in the function since
        this patch.
      sql/table.h:
        Remove the const limitation on variable partition_info, as it can be modified since
        this patch.

      Bug#45012 my_like_range_cp932 generates invalid string · e57a9d6f
      Alexander Barkov authored
      Problem: The functions my_like_range_xxx() returned
      badly formed maximum strings for Asian character sets,
      which made problems for storage engines.
      
      Fix: 
      - Removed a number my_like_range_xxx() implementations,
        which were in fact dumplicate code pieces.
      - Using generic my_like_range_mb() instead.
      - Setting max_sort_char member properly for Asian character sets
      - Adding unittest/strings/strings-t.c, 
        to test that my_like_range_xxx() return well-formed 
        min and max strings.
      
      Notes:
      
      - No additional tests in mysql/t/ available.
        Old tests cover the affected code well enough.

      Bug#52514: mysql 5.1 do_abi_check does not compile w/ gcc4.5 · c36fee08
      Davi Arnaut authored
                 due to GCC preprocessor change
            
      The problem is that newer GCC versions treats missing headers
      as fatal errors. The solution is to use a guard macro to prevent
      the inclusion of system headers when checking the ABI with the
      C Preprocessor.

      Bug#54453: Failing assertion: trx->active_trans when renaming a · b0035c76
      Davi Arnaut authored
                 table with active trx
      
      Essentially, the problem is that InnoDB does a implicit commit
      when a cursor (table handler) is unlocked/closed, creating
      a dissonance between the transaction state within the server
      layer and the storage engine layer. Theoretically, a statement
      transaction can encompass several table instances in a similar
      manner to a multiple statement transaction, hence it does not
      make sense to limit a statement transaction to the lifetime of
      the table instances (cursors) used within it.
      
      Since this particular instance of the problem is only triggerable
      on 5.1 and is masked on 5.5 due 2PC being skipped (assertion is in
      the prepare phase of a 2PC), the solution (which is less risky) is
      to explicitly end the transaction before the cached table is unlock
      on rename table.
      
      The patch is to be null merged into trunk.
      
      mysql-test/include/commit.inc:
        Fix counters, the binlog engine does not get involved anymore.

      BUG#55322: SHOW BINLOG EVENTS increases @@SESSION.MAX_ALLOWED_PACKET · 689a96fc
      Sven Sandberg authored
      Problem: when SHOW BINLOG EVENTS was issued, it increased the value of
      @@session.max_allowed_packet. This allowed a non-root user to increase
      the amount of memory used by her thread arbitrarily. Thus, it removes
      the bound on the amount of system resources used by a client, so it
      presents a security risk (DoS attack).
      
      Fix: it is correct to increase the value of @@session.max_allowed_packet
      while executing SHOW BINLOG EVENTS (see BUG 30435). However, the
      increase should only be temporary. Thus, the fix is to restore the value
      when SHOW BINLOG EVENTS ends.
      The value of @@session.max_allowed_packet is also increased in
      mysql_binlog_send (i.e., the binlog dump thread). It is not clear if this
      can cause any trouble, since normally the client that issues
      COM_BINLOG_DUMP will not issue any other commands that would be affected
      by the increased value of @@session.max_allowed_packet. However, we
      restore the value just in case.
      
      
      mysql-test/suite/rpl/r/rpl_packet.result:
        update result file
      mysql-test/suite/rpl/t/rpl_packet.test:
        Add test that verifies that @@session.max_allowed_packet does not change
        when issuing SHOW BINLOG EVENTS.
        Make previous sub-test clean up.
        Add comments listing the bugs in this test case.
      sql/sql_repl.cc:
        Restore the old value of thd->variables.max_allowed_packet at the
        end of mysql_binlog_send and mysql_show_binlog_events.

      Bug#55061: Build failing on sol 8 x86 - assembler code vs · e98169d5
      Alexey Kopytov authored
                 compiler problem
      
      GCC-style inline assembly is not supported by the Sun Studio
      compilers prior to version 12.
      
      Added a check for the Sun Studio version to avoid using 
      _FPU_GETCW() / _FPU_SETCW() when inline assembly is
       unsupported. This can lead to some differences in floating
      point calculations on Solaris 8/x86 which, however, is not worth
      bothering with Sun-style assembly .il templates.
