eef9ce8c1a Fix for bug #53907: Table dump command can be abused to dump arbitrary tables.
Problem: one with SELECT privilege on some table may dump other table
performing COM_TABLE_DUMP command due to missed check of the table name.

Fix: check the table name.

c2ebb0ac88 Bug #42064: low memory crash when importing hex strings, in
Item_hex_string::Item_hex_string

The status of memory allocation in the Lex_input_stream (called
from the Parser_state constructor) was not checked which led to
a parser crash in case of the out-of-memory error.

The solution is to introduce new init() member function in
Parser_state and Lex_input_stream so that status of memory
allocation can be returned to the caller.

3f8bde448c BUG#53560 CREATE TEMP./DROP TEMP. are not binglogged correctly after a failed statement
This patch fixes two problems described as follows:

1 - If there is an on-going transaction and a temporary table is created or
dropped, any failed statement that follows the "create" or "drop commands"
triggers a rollback and by consequence the slave will go out sync because
the binary log will have a wrong sequence of events.

To fix the problem, we changed the expression that evaluates when the
cache should be flushed after either the rollback of a statment or
transaction.

2 - When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the
OPTION_KEEP_LOG was not set into the thd->options. For that reason, if
the transaction had updated only transactional engines and was rolled
back at the end (.e.g due to a deadlock) the changes were not written
to the binary log, including the creation of the temporary table.
      
To fix the problem, we have set the OPTION_KEEP_LOG into the thd->options
when a "CREATE TEMPORARY TABLE SELECT * FROM" is executed.

sql/log.cc:
  Reorganized the code based on the following functions:
  
  - bool ending_trans(const THD* thd, const bool all);
  - bool trans_has_updated_non_trans_table(const THD* thd);
  - bool trans_has_no_stmt_committed(const THD* thd, const bool all);
  - bool stmt_has_updated_non_trans_table(const THD* thd);
sql/log.h:
  Added functions to organize the code in log.cc.
sql/log_event.cc:
  Removed the OPTION_KEEP_LOG since it must be used only when
  creating and dropping temporary tables.
sql/log_event_old.cc:
  Removed the OPTION_KEEP_LOG since it must be used only when
  creating and dropping temporary tables.
sql/sql_parse.cc:
  When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the
  OPTION_KEEP_LOG was not set into the thd->options.
        
  To fix the problem, we have set the OPTION_KEEP_LOG into the
  thd->options when a "CREATE TEMPORARY TABLE SELECT * FROM"
  is executed.

79e60f0a40 Bug#48157: crash in Item_field::used_tables
MySQL handles the join syntax "JOIN ... USING( field1,
... )" and natural joins by building the same parse tree as
a corresponding join with an "ON t1.field1 = t2.field1 ..."
expression would produce. This parse tree was not cleaned up
properly in the following scenario. If a thread tries to
lock some tables and finds that the tables were dropped and
re-created while waiting for the lock, it cleans up column
references in the statement by means a per-statement free
list. But if the statement was part of a stored procedure,
column references on the stored procedure's free list
weren't cleaned up and thus contained pointers to freed
objects.
      
Fixed by adding a call to clean up the current prepared
statement's free list.

This is a backport from MySQL 5.1

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.

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.
Fixed by checking the table name for compliance similar to how it's 
normally checked by the parser and returning an error message if 
it's not compliant.

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.

  Add skip flag. Only used in server builds.

Problem: "COM_FIELD_LIST is an old command of the MySQL server, before there was real move to only
SQL. Seems that the data sent to COM_FIELD_LIST( mysql_list_fields() function) is not

e925bd737f BUG#48632: Fix for Bug #23300 Has Not Been Backported
To 5.x Release
      
Notes
=====
      
This is a backport of BUG#23300 into 5.1 GA.
      
Original cset revid (in betony):
luis.soares@sun.com-20090929140901-s4kjtl3iiyy4ls2h

Description
===========
      
When using replication, the slave will not log any slow query
logs queries replicated from the master, even if the
option "--log-slow-slave-statements" is set and these take more
than "log_query_time" to execute.
                    
In order to log slow queries in replicated thread one needs to
set the --log-slow-slave-statements, so that the SQL thread is
initialized with the correct switch. Although setting this flag
correctly configures the slave thread option to log slow queries,
there is an issue with the condition that is used to check
whether to log the slow query or not. When replaying binlog
events the statement contains the SET TIMESTAMP clause which will
force the slow logging condition check to fail. Consequently, the
slow query logging will not take place.
                    
This patch addresses this issue by removing the second condition
from the log_slow_statements as it prevents slow queries to be
binlogged and seems to be deprecated.

In statement-based or mixed-mode replication, use DROP TEMPORARY TABLE
to drop multiple tables causes different errors on master and slave, 
when one or more of these tables do not exist. Because when executed
on slave, it would automatically add IF EXISTS to the query to ignore

execution if the query does not expect any errors.

REORGANIZE PARTITION

There were several problems which lead to this this,
all related to bad error handling.

1) There was several bugs preventing the ddl-log to be used for
   cleaning up created files on error.

2) The error handling after the copy partition rows did not close
   and unlock the tables, resulting in deletion of partitions
   which were in use, which lead InnoDB to put the partition to

  The delete of the newly created partition is handled by the ddl-log.

377d710296 BUG#47418 RBR fails, failure with mixup of base/temporary/view
'CREATE TABLE IF NOT EXISTS ... SELECT' statement were causing 'CREATE
TEMPORARY TABLE ...' to be written to the binary log in row-based 
mode (a.k.a. RBR), when there was a temporary table with the same name.
Because the 'CREATE TABLE ... SELECT' statement was executed as 
'INSERT ... SELECT' into the temporary table. Since in RBR mode no 
other statements related to temporary tables are written into binary log,
this sometimes broke replication.

This patch changes behavior of 'CREATE TABLE [IF NOT EXISTS] ... SELECT ...'.
it ignores existence of temporary table with the 
same name as table being created and is interpreted
as attempt to create/insert into base table. This makes behavior of
'CREATE TABLE [IF NOT EXISTS] ... SELECT' consistent with
how ordinary 'CREATE TABLE' and 'CREATE TABLE ... LIKE' behave.

b3dd4d9486 Bug#33982 debug assertion and crash reloading grant tables after sighup or kill
In certain rare cases when a process was interrupted
during a FLUSH PRIVILEGES operation the diagnostic
area would be set to an error state but the function
responsible for the operation would still signal
success. This would lead to a debug assertion error
later on when the server would attempt to reset the
DA before sending the error message.

This patch fixes the issue by assuring that
reload_acl_and_cache() always fails if an error
condition is raised.

The second issue was that a KILL could cause
a console error message which referred to a DA
state without first making sure that such a
state existed.

This patch fixes this issue in two different
palces by first checking DA state before
fetching the error message.

 

sql/sql_acl.cc:
  * Make sure that there is an error to print before attempting to do so.
  * Minor style change: change 1 to TRUE for clarity.
sql/sql_parse.cc:
  * Always fail reload_acl_and_cache() if the query was killed.
sql/sql_servers.cc:
  * Make sure that there is an error to print before attempting to do so.

c8b5804f29 Bug#48157: crash in Item_field::used_tables
MySQL handles the join syntax "JOIN ... USING( field1,
... )" and natural joins by building the same parse tree as
a corresponding join with an "ON t1.field1 = t2.field1 ..."
expression would produce. This parse tree was not cleaned up
properly in the following scenario. If a thread tries to
lock some tables and finds that the tables were dropped and
re-created while waiting for the lock, it cleans up column
references in the statement by means a per-statement free
list. But if the statement was part of a stored procedure,
column references on the stored procedure's free list weren't
cleaned up and thus contained pointers to freed objects.

Fixed by adding a call to clean up the current prepared
statement's free list.

be397eb400 Bug #49137 Replication failure on SBR/MBR + multi-table DROP TEMPORARY TABLE
In statement-based or mixed-mode replication, use DROP TEMPORARY TABLE
to drop multiple tables causes different errors on master and slave, 
when one or more of these tables do not exist. Because when executed
on slave, it would automatically add IF EXISTS to the query to ignore
all ER_BAD_TABLE_ERROR errors.

To fix the problem, do not add IF EXISTS when executing DROP TEMPORARY
TABLE on the slave, and clear the ER_BAD_TABLE_ERROR error after
execution if the query does not expect any errors.

mysql-test/suite/rpl/r/rpl_drop_temp.result:
  Updated for the patch of bug#49137.
mysql-test/suite/rpl/t/rpl_drop_temp.test:
  Added the test file to verify if DROP MULTI TEMPORARY TABLE
  will cause different errors on master and slave, when one or
  more of these tables do not exist.
sql/log_event.cc:
  Added code to handle above cases which are 
  removed from sql_parse.cc
sql/sql_parse.cc:
  Remove the code to issue the 'Unknown table' error, 
  if the temporary table does not exist when dropping 
  it on slave. The above cases decribed in comments
  will be handled later in log_event.cc.

06a1df9181 Bug#48983: Bad strmake calls (length one too long)
The problem is a somewhat common misusage of the strmake function.
The strmake(dst, src, len) function writes at most /len/ bytes to
the string pointed to by src, not including the trailing null byte.
Hence, if /len/ is the exact length of the destination buffer, a
one byte buffer overflow can occur if the length of the source
string is equal to or greater than /len/.

client/mysqldump.c:
  Make room for the trailing null byte.
libmysql/libmysql.c:
  Add comment, there is enough room in the buffer.
  Increase buffer length, two strings are concatenated.
libmysqld/lib_sql.cc:
  Make room for the trailing null byte.
mysys/default.c:
  Make room for the trailing null bytes.
mysys/mf_pack.c:
  Make room for the trailing null byte.
server-tools/instance-manager/commands.cc:
  Copy only if overflow isn't possible in both cases.
server-tools/instance-manager/listener.cc:
  Make room for the trailing null byte.
sql/log.cc:
  Make room for the trailing null byte.
sql/sp_pcontext.h:
  Cosmetic fix.
sql/sql_acl.cc:
  MAX_HOSTNAME already specifies space for the trailing null byte.
sql/sql_parse.cc:
  Make room for the trailing null byte.
sql/sql_table.cc:
  Make room for the trailing null byte.

d13c54351d Remove compiler warnings (Including some warnings from -Wstrict-aliasing)
Don't use static link by default (in compile-pentium) as some new systems doesn't have all static libraries available
Change type for functions in plugin.h:str_mysql_ftparser_param() to const unsigned char and string lengths to size_t.
One effect of the above change is that one needs to include mysql_global.h or define size_t before including plugin.h
