Jakob Unterwurzacher f1dbd19fe9 tests: add hkdf_sanity tests with broken example filesystem
These are deliberately corrupt.

Jakob Unterwurzacher efc88346be cli: enable "-raw64" by default
This brings the CLI options back in sync with the default
feature flags.

Jakob Unterwurzacher f1244b6d06 tests: recreate v1.3 example filesystem
The filesystem was created with a gocryptfs version that ignored
the HKDF flag (hence everything was actually encrypted WITHOUT hkdf).

Fix it by recreating it.
2017-03-07 20:56:50 +01:00
Jakob Unterwurzacher 2362e67a9e cli: add "-hkdf" option
This commit also enables actually passing the HKDF setting to
fusefrontend, this was missing till now.

Jakob Unterwurzacher a80d798c2d tests: reverse: don't run tests that ignore "-plaintextnames" twice
TestMain() runs all tests twice, once with plaintextnames=true and once
with false. Several tests mount their own filesystem and ignore the
plaintextnames variable. It makes no sense to run them twice, so
skip execution when plaintextnames is set.

M. Vefa Bicakci d48ccb3dda Report correct symbolic link dentry sizes
Prior to this commit, gocryptfs's reverse mode did not report correct
directory entry sizes for symbolic links, where the dentry size needs to
be the same as the length of a string containing the target path.

This commit corrects this issue and adds a test case to verify the
correctness of the implementation.

This issue was discovered during the use of a strict file copying program
on a reverse-mounted gocryptfs file system.

Jakob Unterwurzacher b7538fc026 tests: add v1.3 example filesystem

Jakob Unterwurzacher b2f154a9a9 tests: stop calling t.Fatal from example_test_helpers
Calling t.Fatal immeadiately aborts the test, which means the
filesystem will not get unmounted, which means test.bash will
hang.

Jakob Unterwurzacher 8adfbf2dc3 Check for trailing garbage after the password
From the comment:

// CheckTrailingGarbage tries to read one byte from stdin and exits with a
// fatal error if the read returns any data.
// This is meant to be called after reading the password, when there is no more
// data expected. This helps to catch problems with third-party tools that
// interface with gocryptfs.

Add a new "-plaintextnames" filesystem created by gocryptfs v0.7.
There have been no format changes to "-plaintextnames" since then.

Jakob Unterwurzacher 930e597f5a tests: expect mount failure for v0.6 and older example filesystems 2016-06-19 20:04:09 +02:00
Jakob Unterwurzacher 4d067e2de1 tests: adapt for read-only operation
The v0.6 and older example filesystem are mounted read-only
because they are deprecated, so skip the read-write tests.

Jakob Unterwurzacher 96750a7d3c tests: exit with correct error code from TestMain
extpass_test and example_filesystems_test did it wrong,
always returning 0.

Jakob Unterwurzacher 82d87ff8ed Add "-ro" (read-only) flag
From the man page:

  **-ro**
  :      Mount the filesystem read-only

Also add a test.

Jakob Unterwurzacher 218bf83ce3 tests: spin off TestPasswd from TestInit
Also, capture all stderr and stdout but pass "-q".
This way we get to see error messages if there are any, or
spurious output when there should be none due to "-q".

Jakob Unterwurzacher 37d824c9a8 test: add pingpong.bash and pingping-rsync.bash
Mounts two gocryptfs filesystems, "ping" and "pong" and moves the
linux-3.0 kernel tree back and forth between them.

When called as "pingpong-rsync.bash" it uses "rsync --remove-source-files"
for moving the files, otherwise plain "mv".

Jakob Unterwurzacher 5da292828c fusefrontend: fix chown on dangling symlinks
We (actually, go-fuse) used to call Chown() instead of Lchown()
which meant that the operation would fail on dangling symlinks.

Fix this by calling os.Lchown() ourself. Also add a test case
for this.

Jakob Unterwurzacher f58a8d8740 tests: rename extractloop.md5sums to linux-3.0.md5sums
This file will also be used by other tests, so it should
have a generic name.

Jakob Unterwurzacher c2a5303eeb tests: split example_filesystems into its own package
Running these tests from integration_tests' TestMain() was awkward
because they were run twice with unchanged settings.
integration_tests tests everything with OpenSSL and with native
Go crypto, but this does not take affect for the example filesystems.

To make this work, test_helpers is also split into its own package.
