2019-03-17Add contrib/statfs toolJakob Unterwurzacher
This should help debugging https://github.com/rfjakob/gocryptfs/issues/375 and https://github.com/rfjakob/gocryptfs/issues/274 , as MacOS does not have "stat -f".

2019-03-03Allow multiple -extpass argumentsJakob Unterwurzacher
To support arguments containing spaces, -extpass can now be passed multiple times. https://github.com/rfjakob/gocryptfs/issues/289
2019-03-02Include rendered man page in source tarballsJakob Unterwurzacher
This gives users who build from the source tarball, but do not want to install pandoc, access to the man pages. Apperently the gocryptfs homebrew package ships without the man pages at the moment to avoid pandoc. Requested at https://github.com/rfjakob/gocryptfs/issues/355
2019-03-02Update depsJakob Unterwurzacher
go-fuse now has a v1.0.0. release! https://github.com/hanwen/go-fuse/releases/tag/v1.0.0

Error was: tests/matrix/matrix_test.go:101:9: no new variables on left side of :=
2019-02-17ParseHeader: print hexdump on errorJakob Unterwurzacher
Should help debugging https://github.com/rfjakob/gocryptfs/issues/363
2019-02-17nametransform: reject names longer than 255 charsJakob Unterwurzacher
Looks like we allowed creating longer names by accident. Fix that, and add a test that verifies it.

2019-02-17tests: parallel_cp.sh: automount fsJakob Unterwurzacher
Teach the script to automatically mount and unmount.
2019-02-15Update dependenciesJakob Unterwurzacher
Fix for https://github.com/rfjakob/gocryptfs/issues/351 was just merged into go-fuse. Closes https://github.com/rfjakob/gocryptfs/issues/351
2019-02-04dep: update dependenciesv1.7-rc2Jakob Unterwurzacher
This also drops now-unused dependencies.
2019-02-04Disable Trezor supportJakob Unterwurzacher
Trezor support has been broken since Sept 2018 ( https://github.com/rfjakob/gocryptfs/issues/261 ). Disable trezor.go by renaming to trezor.go.broken. This keeps "dep" from having to pull in A LOT OF dependencies: Before: $ du -sh vendor/ 49M vendor/ After: $ du -sh vendor/ 16M vendor/
2019-01-23tests: simplify parallel_cp.shJakob Unterwurzacher
Get rid of one extra directory level. Hopefully makes it easier to follow the debug logs.
2019-01-20tests: darwin: ignore error in TestMvWarningSymlinkJakob Unterwurzacher
https://github.com/rfjakob/gocryptfs/issues/349
2019-01-20fusefronted: comment why Access() does not check context.UidJakob Unterwurzacher
https://github.com/rfjakob/gocryptfs/issues/347
2019-01-20tests: check that we can delete directories with all permissionJakob Unterwurzacher
Regression test for https://github.com/rfjakob/gocryptfs/issues/354
2019-01-20fusefrontend: ensure directories without W or X perms can be deletedJakob Unterwurzacher
This fixed the "Permission denied" bug, but still has the problem that the directory may be replaced behind our back. Mitigated by the fact that we skip the workaround when running as root with -allow_other. https://github.com/rfjakob/gocryptfs/issues/354
2019-01-20tests: matrix: split out directory tests into their own fileJakob Unterwurzacher
matrix_test.go is already too big.
2019-01-20Revert "syscallcompat: drop Faccessat AT_SYMLINK_NOFOLLOW helper"Jakob Unterwurzacher
Breaks mounting on MacOS: unix.Faccessat on Darwin does NOT (yet) support AT_SYMLINK_NOFOLLOW. See d44fe89ba4f3252c5bd00c4f7730197732f2a26a . This reverts commit 0805a63df1b5f915b228727f6074c2506922d0ad.
2019-01-20syscallcompat: drop Faccessat AT_SYMLINK_NOFOLLOW helperJakob Unterwurzacher
unix.Faccessat has added support for AT_SYMLINK_NOFOLLOW in July 2018, https://github.com/golang/sys/commit/bd9dbc187b6e1dacfdd2722a87e83093c2d7bd6e#diff-341484dbbe3180cd7a31ef2ad2d679b6 which means we no longer need our own helper. Closes https://github.com/rfjakob/gocryptfs/issues/347
2019-01-20ctlsock: fix buffer truncation of JSON unmarshal errorJakob Unterwurzacher
In the error case, buf was not restored to the original capacity. Instead of truncating "buf" and restoring (or forgetting to restore) later, introduce the "data" slice. Fixes https://github.com/rfjakob/gocryptfs/issues/356
2019-01-16fusefrontend: Always use intFd() method instead of int(f.fd.Fd()).Sebastian Lackner
2019-01-16fusefrontend: Rework the Utimens handling on macOS.Sebastian Lackner
For Linux, everything effectively stays the same. For both path-based and fd-based Utimens() calls, we use unix.UtimesNanoAt(). To avoid introducing a separate syscall wrapper for futimens() (as done in go-fuse, for example), we instead use the /proc/self/fd - trick. On macOS, this changes quite a lot: * Path-based Utimens() calls were previously completely broken, since unix.UtimensNanoAt() ignores the passed file descriptor. Note that this cannot be fixed easily since there IS no appropriate syscall available on macOS prior to High Sierra (10.13). We emulate this case by using Fchdir() + setattrlist(). * Fd-based Utimens() calls were previously translated to f.GetAttr() (to fill any empty parameters) and syscall.Futimes(), which does not does support nanosecond precision. Both issues can be fixed by switching to fsetattrlist(). Fixes https://github.com/rfjakob/gocryptfs/issues/350
2019-01-15tests: Increase timeout in Mount() function.Sebastian Lackner
This avoids sporadic test failures on macOS.
2019-01-15mount: Replace commas in volume name.Sebastian Lackner
Fixes the following test failure: cli_test.go:534: Failed to mount "[...]/542399800,foo,bar" on "[...]/542399800,foo,bar.mnt": exit status 19
2019-01-15fusefrontend: Print 'too many open files' warning for both short and long names.Sebastian Lackner
While we're at it, also replace os.* constants with syscall.* constants.
2019-01-15fusefrontend_reverse: Delete leftover debug statement.Sebastian Lackner
2019-01-14tests: reduce noise on MacOSJakob Unterwurzacher
This should get rid of Openat: O_NOFOLLOW missing: flags = 0x0 Fchmodat: adding missing AT_SYMLINK_NOFOLLOW flag sys_common_test.go:203: chmod on symlink should have failed, but did not. New mode=0333 UnmountErr: "[...]/057376762.mnt" was not found in MountInfo, cannot check for FD leak and add some context to --- FAIL: TestUtimesNano (0.00s) matrix_test.go:628: no such file or directory See https://github.com/rfjakob/gocryptfs/pull/343#issuecomment-453888006 for full test output
2019-01-14syscallcompat: fix FchmodatNofollow testsJakob Unterwurzacher
FchmodatNofollow dropped the flags parameter.
2019-01-14syscallcompat: rework Fchmodat to FchmodatNofollowJakob Unterwurzacher
We never want Fchmodat to follow symlinks, so follow what Qemu does, and call our function FchmodatNofollow.
2019-01-14syscallcompat: Drop Fstatat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Drop Mkdirat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Drop Symlinkat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Drop Fchownat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Drop Fchmodat emulation on macOS.Sebastian Lackner
On macOS the function has a flags argument, so we don't need the /proc/self/fd trick used on Linux.
2019-01-14syscallcompat: Drop Unlinkat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Drop Renameat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Drop Openat emulation on macOS.Sebastian Lackner
2019-01-14syscallcompat: Use pthread_setugid_np() to implement *User() functions on macOS.Sebastian Lackner
Fixes -allow_other mode on macOS.
2019-01-13fusefrontend: drop last remaining call into loopbackFileSystemJakob Unterwurzacher
The only call forwarded to loopbackFileSystem was Statfs, which is trivial to implement. Implement it and drop loopbackFileSystem, as having it carries the risk that a coding error bypasses the usual encryption/decryption chain.
2019-01-13fusefrontend: Do not pass unsupported flags to Faccessat on macOS.Sebastian Lackner
Fixes mounting of forward mounts on macOS High Sierra.
2019-01-13macos: filter SUID and SGID bits in OpenatUser, MknodatUser, MkdiratUserJakob Unterwurzacher
When gocryptfs runs as root, we don't want to allow people to create SUID root files.
2019-01-12fusefrontend: Preserve SUID/SGID/sticky-bits in openWriteOnlyFile and Rmdir.Sebastian Lackner
Fixes https://github.com/rfjakob/gocryptfs/issues/336 and https://github.com/rfjakob/gocryptfs/issues/337.
2019-01-12fusefrontend: -allow_other: Use SymlinkatUser in Symlink FUSE call.Sebastian Lackner
Instead of manually adjusting the user after creating the symlink, adjust effective permissions and let the kernel deal with it. Related to https://github.com/rfjakob/gocryptfs/issues/338.
2019-01-12fusefrontend: -allow_other: Use MknodatUser in Mknod FUSE call.Sebastian Lackner
Instead of manually adjusting the user and mode after creating the device file, adjust effective permissions and let the kernel deal with it. Related to https://github.com/rfjakob/gocryptfs/issues/338.
2019-01-12fusefrontend: -allow_other: Use MkdiratUser in Mkdir FUSE call.Sebastian Lackner
Revert commit fcaca5fc94d981aa637beb752edc8cb3c2265e96. Instead of manually adjusting the user and mode after creating the directory, adjust effective permissions and let the kernel deal with it. Related to https://github.com/rfjakob/gocryptfs/issues/338.
2019-01-12fusefrontend: -allow_other: Use OpenatUser in Create FUSE call.Sebastian Lackner
Revert commit b22cc03c7516b2003880db8375d26c76d6dff093. Instead of manually adjusting the user and mode after creating the file, adjust effective permissions and let the kernel deal with it. Related to https://github.com/rfjakob/gocryptfs/issues/338.
