UPPER CASE HOST NAME ANYMORE
Description:
It is not possible to drop users with host names with upper case
letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing
with error.
Analysis: Since the fix 11748570 we came up with lower case hostnames
as standard. But in the current bug the hostname is created by
mysql_install_db script is still having upper case hostnames.
So, if we have the hostname with upper case letters like(Tmp_Host_Name)
then we will have as it is stored in the mysql.user table.
In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives
error because we do compare with the lower case of hostname since the
11748570 fix.
Fix: We need to convert the hostname to lower case before storing into
the mysql.user table when we run the mysql_install_db script.
HOST HAS '_' IN THE HOSTNAME
Problem:
=======
'_' and '%' are treated as a wildcards by the ACL code and
this is documented in the manual. The problem with
mysql_install_db is that it does not take this into account
when creating the initial GRANT tables:
--- cut ---
REPLACE INTO tmp_user SELECT @current_hostname,'root','','Y',
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y',
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','',
0,0,0,0 FROM dual WHERE LOWER( @current_hostname) != 'localhost';
--- cut ---
If @current_hostname contains any wildcard characters, then
a wildcard entry will be defined for the 'root' user,
which is a flaw.
Analysis:
========
As per the bug description when we have a hostname with a
wildcard character in it, it allows clients from several other
hosts with similar name pattern to connect to the server as root.
For example, if the hostname is like 'host_.com' then the same
name is logged in mysql.user table. This allows 'root' users
from other hosts like 'host1.com', 'host2.com' ... to connect
to the server as root user.
While creating the intial GRANT tables we do not have a check
for wildcard characters in hostname.
Fix:
===
As part of fix escape character "\" is added before wildcard
character to make it a plain character, so that the one and
only host with the exact name will be able to connect to the
server.
- Removed files specific to compiling on OS/2

1. Fixed the name of the table to proxies_priv
2. Fixed the column names to be of the form Capitalized_lowecarse instead of
Capitalized_Capitalized
3. Added Timestamp and Grantor columns
4. Added tests to plugin_auth to check the table structure
5. Updated the existing tests

Machines with hostname set to "localhost" cause uniqueness errors in
the SQL bootstrap data.
Now, insert zero lines for cases where the (lowercased) hostname is
the same as an already-inserted 'localhost' name. Also, fix a few tests
that expect certain local accounts to have a certain host name.
Fix is to remove any references to the current hostname when running
mysql_install_db --cross-bootstrap. (The dist-hook make target makes
this call, and the resulting data directory is included in the source
distribution as win/data/*.)
Also, a few other clean-ups to mysql_install_db while there.
were accidentally removed during a previous rototill of this
code. Fixes bug#27692.
While it can be argued we should strive to provide a 'secure by
default' installation, this happens to be the setup currently
documented in the manual as the default, so defer changes that
improve security out of the box to a co-ordinated effort later
on.
For now, make a note about the test databases and anonymous user
in mysql_install_db and recommend that mysql_secure_installation
be ran for users wishing to remove these defaults.
