# In older versions of swiftonfile, metadata stored as xattrs of files
# were serialized using PICKLE format. The PICKLE format is vulnerable to

# Deserializing pickled metadata can result in malicious code being
# executed if an attacker has stored malicious code as xattr from filesystem
# interface. Although, new metadata is always serialized using JSON format,
# existing metadata already stored in PICKLE format can be loaded by setting
# the following option to 'on'.
# You can turn this option to 'off' once you have migrated all your metadata
# from PICKLE format to JSON format using swiftonfile-migrate-metadata tool.
