Today CVE-2020-7221 was publicly discussed on oss-sec [1]. MariaDB
upstream had not mentioned this CVE in their last release notes. The CVE
is related to auth-pam and the possibility of a local mariadb to root
user exploit in the mysql_install_db script.
Upstream has made amendments to the script, but according to the oss-sec
posts the folder permissions were not updated as they should have been.
In OpenWrt the script mysql_install_db is actually patched to never run
the commands in question. This has been this way since MariaDB 10.4 was
made available.
Still, the directory permissions set by the postinstall script are too
lax. To quote the discoverer of the issue, Matthias Gerstner from Suse,
they exhibit "the dangerous situation of a setuid-root binary residing
in a directory owned by an unprivileged user".
This commit fixes this by changing the permissions to the following:
root:mariadb 0750 /usr/lib/mariadb/plugin/auth_pam_tool_dir
This way the setuid-root binary is only available to root and the
mariadb user, while at the same time the mariadb user has no ownership
of the directory.

MariaDB 10.4 includes some changes in sql/sql_statistics.cc that require
std::fmin and std::fmax. But these functions aren't available when
libstdc++ is compiled against uClibc, because uClibc doesn't pass the
test when libstdc++ checks for C99 math that supports "TR1" facilities
(macro: GLIBCXX_CHECK_C99_TR1).
Hence compilation fails:

val = std::fmax(estimate_total_distincts * (rows - nulls) / rows, 1.0);
This commit updates package dependencies to prevent a build against
uClibc. There is no reason to waste CPU cycles on the build bots.
The dependencies are also tidied up. In the past it made sense to define
MARIADB_COMMON_DEPENDS and MARIADB_COMMON_DEPENDS_EXE, because the
server had different dependencies compared to the library. But since the
library is now in its own package we can remove the differentiation.

This way when only wanting the library nobody needs to download and
compile the server package, saving space and time. Also this way we can

At present there are some flaws related to configuration, also related
to the packaging of mariadb. For starters there are complaints that the
configuration is too static.
To address this a new configuration layout is introduced. The primary
configuration file (my.cnf) is changed so that it now only includes
further configuration files in the directory /etc/mysql/conf.d. More
default configuration files are added for the server and the client.
This is the new default configuration.
With these changes it's possible for the user to select if they want to
change the default configuration (in conf.d/*.cnf) or if they want to
drop their own files into conf.d instead. If the user .cnf files are
read after the default .cnf files (files are included in alphabetical
order), they will overwrite the settings from the default configuration.
The other flaw is that the my.cnf file is included in mariadb-server.
But that doesn't really fit the requirements, as the client also uses
the configuration file(s). To accomodate this a new package
mariadb-common is added. It installs the shared my.cnf file.
The remaining changes add base packages, both for the server and the
client. These are meant as foundation for the packages containing the
respective binaries. In summary they will install the configuration,
small miscellaneous files (SQL scripts etc.) and the user "mariadb".
That means that everything is ready for the binaries, like mysql and
mysqld. If there is not enough space left on flash memory, the user can
just drop the binaries on a pendrive, link them to /usr/bin and get
started.
The ideas and configuration files were copied from Debian. Some
amendments were made.

This commit deals with changes related to plugins and how they're built
or disabled.
Currently a lot of plugins are packaged which are merely for tests or
plain examples. Other distros do not bundle these, hence this commit
does away with them.
A few new plugins are added related to PAM and Kerberos (auth_gssapi,
auth_gssapi_client and auth_pam).
The BuildPlugin template is refactored to also allow building of library
plugins (needed for auth_gssapi_client). The template is also cleaned up
- some extraneous dollar signs are removed and the install function is
now defined outside the template.
Unwanted plugins/engines are now turned off efficiently (without using
cmake variables) by blanking CMakeLists.txt files in the associated
folders. The idea was lifted from Gentoo.
ha_sequence is now built into the server. This is an upstream
preference. The plugin is about 30 kbytes in size, so there is no harm
adding it into the server, which weighs in at about 15 Mbytes anyway.
Last but not least the auth_socket plugin is now also built into the
server. This allows the local root user to login to the database
without a password being set. This makes maintenance easier without
being detrimental to security. The idea was lifted from Debian.

libedit changed its interface a while back. mariadb currently does not
recognize this interface and instead uses a static old readline version.
It does not link in the system readline due to licence incompatibility.
This commit adds a patch that enables mariadb to detect and use the
system libedit. The patch was sent upstream already ([1]).

Historically programs added /usr/lib/mysql to the library search path when
linking. mariadb does not do so anymore, although even its mysql_config
script suggests to use this path. When an old version of the library still
resides in this directory (like from an old mysql installation) it will be
linked against instead of the current library which is in /usr/lib.
To prevent this simply install symlinks from the staging libs in /usr/lib
into /usr/lib/mysql. This fixes build failures on the build bots which are
seen with libzdb and libdbi-drivers.
