2018-02-03Fix assignment error in Unix2syscall by converting Timespec into Nsec (#203)Felix Lechner
$ go.gcc build # github.com/rfjakob/gocryptfs/internal/syscallcompat internal/syscallcompat/unix2syscall_linux.go:32:13: error: incompatible types in assignment (cannot use type int64 as type syscall.Timespec_sec_t) s.Atim.Sec = u.Atim.Sec ^
2018-02-03MANPAGE: improve markdown renderingJakob Unterwurzacher
The man page is rendered on github at https://github.com/rfjakob/gocryptfs/blob/master/Documentation/MANPAGE.md . Improve formatting a little.
2018-02-01gccgo: replace syscall.NAME_MAX with unix.NAME_MAXJakob Unterwurzacher
For some reason the syscall.NAME_MAX constant does not exist on gccgo, and it does not hurt us to use unix.NAME_MAX instead. https://github.com/rfjakob/gocryptfs/issues/201
2018-01-31syscallcompat: switch from syscall.Getdents to unix.GetdentsJakob Unterwurzacher
On mips64le, syscall.Getdents() and struct syscall.Dirent do not fit together, causing our Getdents implementation to return garbage ( https://github.com/rfjakob/gocryptfs/issues/200 and https://github.com/golang/go/issues/23624 ). Switch to unix.Getdents which does not have this problem - the next Go release with the syscall package fixes is too far away, and will take time to trickle into distros.

2018-01-28added usage of reverse mode to READMEKenneth Newwood
2018-01-25syscallcompat: hardcode maxReclen = 280 for all architecturesJakob Unterwurzacher
Due to padding between entries, it is 280 even on 32-bit architectures. See https://github.com/rfjakob/gocryptfs/issues/197 for details.
2018-01-25syscallcompat: fix reversed warning outputJakob Unterwurzacher
We used to print somewhat strange messages: Getdents: corrupt entry #1: Reclen=276 > 280. Returning EBADR Reported at https://github.com/rfjakob/gocryptfs/issues/197
2018-01-25Update README.mdrfjakob
README: add missing word
2018-01-25fusefrontend: drop unused haveGetdents warningJakob Unterwurzacher
We don't actually print that warning anymore.
2018-01-25syscallcompat: explain why we don't use syscall.ParseDirent()Jakob Unterwurzacher
syscall.ParseDirent only returns the NAMES, we want everything.
2018-01-21Documentation: update xfstests outputv1.4.3Jakob Unterwurzacher
Also update the v1.4.3 release date to today. The release was delayed one day.
2018-01-21Documentation: add extractloop example outputJakob Unterwurzacher
2018-01-20Update changelog for 1.4.3Jakob Unterwurzacher
2018-01-20Travis CI: also build with vendored dependenciesJakob Unterwurzacher
2018-01-20dep: update dependenciesJakob Unterwurzacher
We needed a newer version of x/sys/unix to compile, and we want the fixes in go-fuse.
2018-01-20MacOS: rely on OSXFuse to create the mountpointJakob Unterwurzacher
As reported in https://github.com/rfjakob/gocryptfs/issues/194 , OSXFuse creates the mountpoint if it does not exist.
2018-01-20MANPAGE: improve description of -o and -koJakob Unterwurzacher
Was unclear for new users - see https://github.com/rfjakob/gocryptfs/issues/194
2018-01-17fusefrontend_reverse: use OpenNofollow in virtualFile.GetAttrJakob Unterwurzacher
Makes it robust against symlink races. Final piece, closes https://github.com/rfjakob/gocryptfs/issues/165
2018-01-17fusefrontend_reverse: use OpenNofollow in findLongnameParentJakob Unterwurzacher
Protects findLongnameParent against symlink races. Also add comments to several functions along the way. Reported at https://github.com/rfjakob/gocryptfs/issues/165
2018-01-17fusefronted: add PlaintextNames special-cases for Create & RenameJakob Unterwurzacher
gocryptfs.longname.XXX files were considered magic in PlaintextNames mode, which was wrong. Fix that and add tests. Fixes https://github.com/rfjakob/gocryptfs/issues/174
2018-01-16Run go fmtJakob Unterwurzacher
2018-01-16MacOS: rely on OSXFuse to create mountpoint below /VolumesJakob Unterwurzacher
OSXFuse automatically creates the mountpoint if it is below /Volumes because this would require root permissions which the user might not have. Reported at https://github.com/rfjakob/gocryptfs/issues/194

Provide basic man page for xray tool
2018-01-10Fix spellingFelix Lechner
2018-01-07package-source.bash: archive HEAD instead of masterJakob Unterwurzacher
To be able to check out an older version and create a tarball from it, let `git archive` operate on HEAD. This used to be broken in a bad way: we use `git describe` which operates on HEAD to name the tarball, but always archived HEAD.
2018-01-07package-source.bash: also create source-only tarballJakob Unterwurzacher
We used to only create a source + dependecies tarball, but having a source-only tarball makes packaging deb/rpm easier.
2017-12-25fusefrontend: Use Linkat syscall to implement LinkSebastian Lackner
2017-12-25fusefrontend: Handle PlaintextNames mode in LinkSebastian Lackner
In PlaintextNames mode the "gocryptfs.longname." prefix does not have any special meaning. https://github.com/rfjakob/gocryptfs/issues/174
2017-12-25Pinned the link to line 38 of performance.txt to version 1.4.1 since ↵Rohan Talip
https://github.com/rfjakob/gocryptfs/commit/f0e29d9b90b63d5fbe4164161ecb0e1035bb4af4#diff-86b7f3262ae352959ee0e04cccaac1b0 added an extra line.
2017-12-11fusefrontend_reverse: Use O_DIRECTORY in OpenDir implementationSebastian Lackner
Also get rid of the defer - it is not really necessary here.
2017-12-11fusefrontend_reverse: Reject access to device nodes in newFile functionSebastian Lackner
Steps to reproduce: * Create a regular reverse mount point * Create a file "test" in the original directory * Access the corresponding encrypted directory in the mount point (ls <encrypted dir>) * Quickly delete the file in the original data - instead create a device node * Access the file again, it will access the device node and attempt to read from it Fixes https://github.com/rfjakob/gocryptfs/issues/187
2017-12-07fusefrontend_reverse: Use openBackingDir in GetAttrSebastian Lackner
Also fixes 48bd59f38843e5ebd4e4c9f666f1aea1c9990803 - the directory FD should also be closed in case of an error.
2017-12-07fusefrontend_reverse: Use openBackingDir in ReadlinkSebastian Lackner
2017-12-07fusefrontend_reverse: fix fd leak in GetAttrJakob Unterwurzacher
Fixes https://github.com/rfjakob/gocryptfs/issues/184
2017-12-07fusefrontend_reverse: secure Access against symlink races (somewhat)Jakob Unterwurzacher
Unfortunately, faccessat in Linux ignores AT_SYMLINK_NOFOLLOW, so this is not completely atomic. Given that the information you get from access is not very interesting, it seems good enough. https://github.com/rfjakob/gocryptfs/issues/165
2017-12-07syscallcompat: add FaccessatJakob Unterwurzacher
Add faccessat(2) with a hack for symlink, because the kernel does not actually looks at the passed flags. From man 2 faccessat: C library/kernel differences The raw faccessat() system call takes only the first three argu‐ ments. The AT_EACCESS and AT_SYMLINK_NOFOLLOW flags are actually implemented within the glibc wrapper function for faccessat().
2017-12-06tets_helpers: handle t=nil in InitFSJakob Unterwurzacher
The reverse tests call InitFS with t=nil. By calling panic we get a better error message instead of a generic nil pointer dereference.
2017-12-06fusefrontend_reverse: secure Readlink against symlink racesJakob Unterwurzacher
...by using Readlinkat. Tracking ticket: https://github.com/rfjakob/gocryptfs/issues/165
2017-12-06syscallcompat: add ReadlinkatJakob Unterwurzacher
We need readlinkat to implement Readlink symlink-race-free.
2017-12-06syscallcompat: add Darwin version of unix2syscallJakob Unterwurzacher
The "Atim" field is called "Atimespec" on Darwin, same for Mtim and Ctim.
2017-12-06fusefrontend_reverse: secure GetAttr against symlink racesJakob Unterwurzacher
...by using the OpenNofollow helper & Fstatat. Also introduce a helper to convert from unix.Stat_t to syscall.Stat_t. Tracking ticket: https://github.com/rfjakob/gocryptfs/issues/165
2017-12-05syscallcompat: OpenNofollow: use O_DIRECTORY flagJakob Unterwurzacher
...when opening intermedia directories to give us an extra layer of safety. From the FreeBSD man page: This flag can be used to prevent applications with elevated privileges from opening files which are even unsafe to open with O_RDONLY, such as device nodes.
2017-12-05fusefrontend_reverse: secure OpenDir against symlink racesJakob Unterwurzacher
...by using the new OpenNofollow helper. The benchmark shows a small but acceptable performance loss: $ ./benchmark-reverse.bash LS: 2.182 CAT: 18.221 Tracking ticket: https://github.com/rfjakob/gocryptfs/issues/165
2017-12-05syscallcompat: OpenNofollow: fix relPath="" caseJakob Unterwurzacher
Sometimes want to open baseDir itself. This case was broken, fix it.
2017-12-05Documentation: Add reverse mode benchmark resultsJakob Unterwurzacher
2017-12-03syscallcompat: convert Getdents to fd input, add emulationJakob Unterwurzacher
Now that we have Fstatat we can use it in Getdents to get rid of the path name. Also, add an emulated version of getdents for MacOS. This allows to drop the !HaveGetdents special cases from fusefrontend. Modify the getdents test to test both native getdents and the emulated version.
2017-12-03syscallcompat: add Fstatat + emulation + testJakob Unterwurzacher
Fstatat has recently been added to x/sys/unix. Make it available for use in gocryptfs.
2017-12-02fusefrontend_reverse: secure StatFs agains symlink racesJakob Unterwurzacher
...by ignoring the path that was passed in. https://github.com/rfjakob/gocryptfs/issues/165
