Allow setting FSCRYPT_CONSISTENT_OUTPUT=1 in the environment to cause
policies and protectors to sorted by last modification time. The CLI
tests need this to make the output of 'fscrypt' ordered in a consistent
way with regard to the operations performed.
|
|
Allow overriding the mountpoint where login protectors are stored by
setting the FSCRYPT_ROOT_MNT environmental variable. The CLI tests need
this to avoid touching the real "/".
|
|
Allow overriding the location of fscrypt.conf by setting the
FSCRYPT_CONF environmental variable. The CLI tests need this to avoid
touching the real /etc/fscrypt.conf.

There's no need to include the build time, author, and copyright info
in the output of "fscrypt --version". This information is:
- Overly complex (the current string is hard to parse)
- Inaccurate (there are other authors than just me)
- Unnecessary (the Apache 2 license is for Source Code)
- Makes reproducible builds impossible
The default version string is just fine.

Add support for 'fscrypt lock'. This command "locks" a directory,
undoing 'fscrypt unlock'.
When the filesystem keyring is used, 'fscrypt lock' also detects when a
directory wasn't fully locked due to some files still being in-use. It
can then be run again later to try to finish locking the files.

These were found by a combination of manual review and a custom script
that checks for common errors.
Also removed an outdated sentence from the comment for setupBefore().
|
|
Our current build tags set off the linter. We will later add in more
comprehensive build tags that will be properly formatted.

This command adds in the "fscrypt metadata" command. This command allows
advanced users to manipulate the metadata directly instead of just
creating a policy or protector as an option when encrypting a directory.
As some of these methods will require certain flags, error handling for
this case is also added. As the change passphrase method must indicate
when a old vs new password is necessary, additional KeyFuncs are added
which add this indicator.

This commit adds in the status command, which has 2 functions, allowing
the user to query the state of the entire system or a specific
filesystem.
This commit also adds in the purge command to remove all policy keys
corresponding to a filesystem. This (along with getting the unlock
status for the status commands) uses additional keyctl functionality in
the crypto and actions packages.

This commit adds in the framework for adding commands and subcommands to
the fscrypt tool. This commit adds in the "setup", "encrypt", and
"unlock" commands. Additional information can be found by running:
fscrypt <command> --help.
This commit defines how flags are parsed and errors are handled. It also
creates an extensible framework for prompting the user for information.

This commit adds in a stub fscrypt program. The binary just tells the
time and the tests do nothing, but the Makefile will build them! This
commit also adds documentation to the README that explains how to get,
build, run, test, format, lint, and install the code.
Also note that the executable is now in the cmd/fscrypt directory. The
library implementing the core functionality will be at the root. This
is essentially point 2 of https://medium.com/@benbjohnson/structuring-applications-in-go-3b04be4ff091
