2018-09-18main: sanitize commas from fsnameJakob Unterwurzacher
The cipherdir path is used as the fsname, as displayed in "df -T". Now, having a comma in fsname triggers a sanity check in go-fuse, aborting the mount with: /bin/fusermount: mount failed: Invalid argument fuse.NewServer failed: fusermount exited with code 256 Sanitize fsname by replacing any commas with underscores. https://github.com/rfjakob/gocryptfs/issues/262
2018-09-08fusefrontend: use OpenDirNofollow in openBackingDirJakob Unterwurzacher
Rename openBackingPath to openBackingDir and use OpenDirNofollow to be safe against symlink races. Note that openBackingDir is not used in several important code paths like Create(). But it is used in Unlink, and the performance impact in the RM benchmark to be acceptable: Before $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.bYO: gocryptfs v1.6-12-g930c37e-dirty; go-fuse v20170619-49-gb11e293; 2018-09-08 go1.10.3 WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 1.07979 s, 243 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0.882413 s, 297 MB/s UNTAR: 16.703 MD5: 7.606 LS: 1.349 RM: 3.237 After $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.jK3: gocryptfs v1.6-13-g84d6faf-dirty; go-fuse v20170619-49-gb11e293; 2018-09-08 go1.10.3 WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 1.06261 s, 247 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0.947228 s, 277 MB/s UNTAR: 17.197 MD5: 7.540 LS: 1.364 RM: 3.410
2018-09-08tests: restore Go 1.7 compatibilityJakob Unterwurzacher
Go 1.7 does not have t.Name() yet.
2018-09-08syscallcompat: use O_PATH in OpenDirNofollowJakob Unterwurzacher
This fixes the "0100 directory" problem in reverse mode, and should be slightly faster.
2018-09-08tests: add chmod testJakob Unterwurzacher
Makes sure we don't add regressions when fixing https://github.com/rfjakob/gocryptfs/issues/259
2018-09-08tests: restore TestUtimesNanoSymlinkJakob Unterwurzacher
The function seems to have been renamed by 426b9536 by mistake. Rename it back so the test is run again.
2018-09-08main: don't read the config file twice (fix pipe bug)Jakob Unterwurzacher
Instead, first Load() the file, then DecryptMasterKey(). Fixes https://github.com/rfjakob/gocryptfs/issues/258
2018-09-08configfile: add LoadAndDecrypt wrapperJakob Unterwurzacher
Callers that do not want to decrypt the masterkey should call plain Load(). https://github.com/rfjakob/gocryptfs/issues/258
2018-08-15main: add -e as an alias for -excludeJakob Unterwurzacher
2018-08-11reverse mode: add --exclude optionJakob Unterwurzacher
https://github.com/rfjakob/gocryptfs/issues/235
2018-08-11tests: VerifyExistence: panic on inconsistent resultsJakob Unterwurzacher
In the past we did not check whether all methods of checking the file return the same result. We should.
2018-07-01fsck: handle sparse files efficiently, fix xfstests generic/285Jakob Unterwurzacher
If we encounter a 128KB block of zeros, try to skip to the next data section by calling File.SeekData(). This fixes xfstests generic/285, which creates a 17TB sparse file, and runs fsck afterwards. Without this optimization, fsck would take ages.
2018-07-01trezor: add TrezorPayloadJakob Unterwurzacher
TrezorPayload stores 32 random bytes used for unlocking the master key using a Trezor security module. The randomness makes sure that a unique unlock value is used for each gocryptfs filesystem.
2018-07-01configfile: reduce function name stutterJakob Unterwurzacher
configfile.LoadConfFile() -> configfile.Load() configfile.CreateConfFile() -> configfile.Create()
2018-07-01trezor: exit with usage error if used together with -extpassJakob Unterwurzacher
Using an external program for the Trezor PIN is not supported at the moment.
2018-07-01trezor: add basic "-init -trezor" testJakob Unterwurzacher
Verify that the Trezor feature flag is set after "-init -trezor".
2018-07-01trezor: add skeleton for Trezor supportJakob Unterwurzacher
readpassword.Trezor() is not implemented yet and returns a hardcoded dummy key.
2018-06-07main: accept -dev, -nodev, -suid, -nosuid, -exec, -noexecJakob Unterwurzacher
When mounted via /etc/fstab like this, /a /b fuse.gocryptfs default 0 0 we always get extra options passed. As reported by @mahkoh at https://github.com/rfjakob/gocryptfs/pull/233 : mount passes `-o noexec` if `-o user` is set and `-o exec` is not set. If both `-o user` and `-o exec` are set, it passes `-o exec`. Make these options work, and in addtion, also make -suid and -rw work the same way. Reported-by: @mahkoh
2018-06-05main: make prefixOArgs errors testableJakob Unterwurzacher
By returning an error instead of calling os.Exit, error cases can be tested easily. Error cases were not tested until now.
2018-05-27xattr: use LGet/LSet etcJakob Unterwurzacher
Support has been merged into the xattr package ( https://github.com/pkg/xattr/pull/29 ), use it.
2018-05-17tests: add "mv broken symlink" testJakob Unterwurzacher
This currently fails because we do not use llistxattr yet.
2018-05-15xattr: return EOPNOTSUPP for unsupported attributesJakob Unterwurzacher
mv is unhappy when we return EPERM when it tries to set system.posix_acl_access: mv: preserving permissions for ‘b/x’: Operation not permitted Now we return EOPNOTSUPP like tmpfs does and mv seems happy.
2018-05-10fsck: update testcases with binary xattrsJakob Unterwurzacher
2018-05-10xattr: optimize storage, store as binary instead of bae64Bolshevik
Values a binary-safe, there is no need to base64-encode them. Old, base64-encoded values are supported transparently on reading. Writing xattr values now always writes them binary.
2018-05-04tests: example_filesystems: create a private copy in /tmpJakob Unterwurzacher
The tests write to the example_filesystems folder, which 1) May leave your source tree in a modified state 2) Triggers test failures when the fsck tests run concurrently, which happens on Travis CI every now and then. Fix both problem by copying the example_filesystems folder to a private location in /tmp.
2018-04-27tests: helpers: fix a few error reportsJakob Unterwurzacher
These were using stale err values.
2018-04-08Fix the easy golint warningsJakob Unterwurzacher
Reported by https://goreportcard.com/report/github.com/rfjakob/gocryptfs
2018-04-08tests: retry umountJakob Unterwurzacher
Gnome may still have files open causing spurious test failures.
2018-04-07tests: cli_test: fix fd leakJakob Unterwurzacher
One fd leak found in TestMountBackground.
2018-04-07tests: matrix: check for fd leaksJakob Unterwurzacher
And fix two in test_helpers.Mount(). Leftover fds can cause an unmount failure like this later: fusermount: failed to unmount /tmp/gocryptfs-test-parent/873632270/default-plain: Device or resource busy so try to catch them early.
2018-04-02fsck: add xattr supportJakob Unterwurzacher
With testcases.
2018-04-02fsck: test against example_filesystemsJakob Unterwurzacher
2018-04-02fsck: clean up log outputJakob Unterwurzacher
Make sure we get only 1 warning output per problem. Also, add new corruption types to broken_fs_v1.4.
2018-04-02fsck: add initial implementationJakob Unterwurzacher
Most corruption cases except xattr should be covered. With test filesystem. The output is still pretty ugly. xattr support will be added in the next commits.
2018-04-01tests: add a few explicit file Close() in matrix_testJakob Unterwurzacher
These can cause EBUSY errors when unmounting.
2018-04-01main: add "-fsck" flagJakob Unterwurzacher
The fsck operation is not yet implemented, this commits just adds the flag and improves cli flag handling.
2018-03-28Switch from private copy to pkg/xattrJakob Unterwurzacher
Now that https://github.com/pkg/xattr/pull/24 has been merged there is no reason to keep our private copy. Switch to the upstream version.
2018-03-26tests: replace xattr.SupportedJakob Unterwurzacher
This function has been deprecated by the pkg/xattr upstream, so write our own.
2018-03-25fusefrontend: handle empty xattrs efficientlyJakob Unterwurzacher
We handle empty files by storing an actual empty file on disk. Handle xattrs similarily and encrypt the empty value to the empty value.
2018-03-25fusefrontend: add xattr supportJakob Unterwurzacher
At the moment, only for reverse mode. https://github.com/rfjakob/gocryptfs/issues/217
2018-03-24test_helpers: add SwitchTestParentDirJakob Unterwurzacher
SwitchTestParentDir changes testParentDir. This is used when you want to perform tests on a special filesystem. For example, the xattr tests cannot run on tmpfs and use /var/tmp instead of /tmp.
2018-03-22Add `-masterkey=stdin` functionalityJakob Unterwurzacher
https://github.com/rfjakob/gocryptfs/issues/218
2018-03-13tests: extractloop.sh: better cleanup logic, handle missing /procJakob Unterwurzacher
macos does not have /proc, so don't try to read it.
2018-03-13tests: extractloop.sh: don't abort if md5sum is missingJakob Unterwurzacher
MacOS does not have it installed by default.
2018-03-07macos: extractloop.sh: exclude symlink & mute ln error messageJakob Unterwurzacher
Extracting the symlink fails with linux-3.0/arch/microblaze/boot/dts/system.dts: Can't set permissions to 0755 so just exclude it. The ln error Looks scary but is harmless, so get rid of it. The symlink is only created to make it more convenient to view the csv log.
2018-03-07macos: tests: make extractloop.bash work on macosJakob Unterwurzacher
macos' bash and ln lack a few features we used.
2018-03-07tests: convert remaining wget calls to dl-linux-tarball.bash helperJakob Unterwurzacher
Makes the scripts work when wget is not available (macos)
2018-03-07macos: tests: use curl of wget is not availableJakob Unterwurzacher
2018-03-06tests: drop "-z" from fusermount to catch forgotten fdsJakob Unterwurzacher
macos does not have lazy unmount, so let's not use it on linux either. If the unmount fails, run "lsof" to find the open file. Also fix the first bug we found this way.
2018-03-05macos: fix fd leak in reverse testsJakob Unterwurzacher
Causes "Resource busy" unmount failures on macos
