Incompatible Change: The secure_file_priv system variable is used to limit the effect of data import and export operations. The following changes have been made to how the server handles this variable:
secure_file_priv can be set to NULL to disable all import and export operations.
The server checks the value of secure_file_priv at startup and writes a warning to the error log if the value is insecure. A non-NULL value is considered insecure if it is empty, or the value is the data directory or a subdirectory of it, or a directory that is accessible by all users. If secure_file_priv is set to a nonexistent path, the server writes an error message to the error log and exits.
Previously, the secure_file_priv system variable was empty by default. Now the default value is platform specific and depends on the value of the INSTALL_LAYOUT CMake option, as shown in the following table.
INSTALL_LAYOUT Value | Default secure_file_priv Value |
|---|---|
STANDALONE, WIN |
NULL |
DEB, RPM, SLES, SVR4 |
/var/lib/mysql-files |
| Otherwise | mysql-files under the CMAKE_INSTALL_PREFIX value |
To specify the default secure_file_priv value explicitly if you are building from source, use the new INSTALL_SECURE_FILE_PRIVDIR CMake option. To specify a directory for the embedded server, set the new INSTALL_SECURE_FILE_PRIV_EMBEDDEDDIR option. Its default value is NULL.
