      BUG#26489 Corruption in relay logs · cbcbfd77
      unknown authored
      Here is the scenario that causes the failure.(by Mats)
      
      1. The to-be corrupt log event (let's call it X), is split into two
         packets B and C on the network level (net_write_buff()). The parts
         are X = (x',x''). The part x' ends up in packet B and part x''
         ends up in packet C. Prior to the corrupt event X, the event Y has
         been written successfully, but has been split into two packets as
         well, which we call (y',y'').
      2. The master sends packet A = (y'',x') to the slave, increases the
         packet sequence number, the slave receives the packet, but fails
         to reply before the master gets a timeout.
      3. Since the master got a timeout, it reports failure, and aborts
         sending the binary log by exiting mysql_binlog_send(). However, it
         leaves the buffer intact, still holding y'' (but not x', since the
         write_pos is not increased).
      4. After exiting mysql_binlog_send(), the master does a
         disconnection of the client thread, which involves sending an
         error message e to the client (i.e., the slave).
      5. In this case, net_write_buff() is used again, but this time the
         old contents of the packet is used so that the new packet is
         D = (y'',e). Note that this will use a new packet sequence number,
         since the packet number was increased in step 2.
      6. The slave receives the tail y'' of the Y log event, concatenates
         this with x' (which it already received), and writes the event
         (x',y'') it to the relay log since it hasn't noticed anything is
         amiss.
      7. It then tries to read more bytes, which is either e (if the length
         given for X just happened to match the length given for Y, or just
         plain garbage because the slave is out of sync with what is
         actually sent.
      8. After a while, the SQL thread tries to execute the event (x',y''),
         which is very likely to be just nonsense.
      
      The problem can be fixed by not resetting net->error after the call of 
      mysql_binlog_send, so the error message will not be sent and the connection
      will be closed.
      
      
      sql/sql_parse.cc:
        Do not reset net->error, if net->error == 2, we should not try to use the connection again

      BUG#33862 completely failed DROP USER statement gets replicated · c78852a5
      unknown authored
      The problem is when create/rename/drop users, the statement was logged regardless of error, even if no data has been changed, the statement was logged.
      
      After this patch, create/rename/drop users don't write the binlog if the statement makes no changes, if the statement does make any changes, log the statement with possible error code.

                read_buffer_size set on master
      BUG#33413 show binlog events fails if binlog has event size of close
                to max_allowed_packet
      
      
      The size of Append_block replication event was determined solely by
      read_buffer_size whereas the rest of replication code deals with
      max_allowed_packet.
      When the former parameter was set to larger than the latter there were
      two artifacts: the master could not read events from binlog;
      show master events did not show.
      
      Fixed with 
      - fragmenting the used io-cached buffer into pieces each size of less
        than max_allowed_packet (bug#30435)
      - incrementing show-binlog-events handling thread's max_allowed_packet
        with the max estimated for the replication header size
      
      
      include/my_sys.h:
        accessor-macros added in order not to mess with the io cache's implementation
        details in code that merely exploits the io-cache.

      Wrt to future_group_master_log_position, there is no issue.

      failure on the slave.

      BUG#31793 (log event corruption causes crash): · 4d5c90aa
      unknown authored
      When running mysqlbinlog on a 64-bit machine with a corrupt relay log,
      it causes mysqlbinlog to crash. In this case, the crash is caused
      because a request for 18446744073709534806U bytes is issued, which
      apparantly can be served on a 64-bit machine (speculatively, I assume)
      but this causes the memcpy() issued later to copy the data to segfault.
      
      The request for the number of bytes is caused by a computation
      of data_len - server_vars_len where server_vars_len is corrupt in such
      a sense that it is > data_len. This causes a wrap-around, with the
      the data_len given above.
      
      This patch adds a check that if server_vars_len is greater than
      data_len before the substraction, and aborts reading the event in
      that case marking the event as invalid. It also adds checks to see
      that reading the server variables does not go outside the bounds
      of the available space, giving a limited amount of integrity check.
      
      
      mysql-test/r/mysqlbinlog.result:
        Result change.
      mysql-test/t/mysqlbinlog.test:
        Adding test that it fails gracefully for a corrupt relay log.
      sql/log_event.cc:
        Adding check that status var length does not cause wrap-around
        when performing subtraction. Extending get_str_len_and_pointer() to
        check that the string can actually be read without reading outside
        bounds. Adding checks when reading server variables from the Query-
        log_event so that the variable can really be read. Abort reading
        and mark the event as invalid otherwise.
