2019-01-04fusefrontend: fix setting xattrs on directoriesJakob Unterwurzacher
Directories cannot be opened read-write. Retry with RDONLY.
2019-01-02fusefrontend: use O_RDONLY in the ListXAttr fallback pathJakob Unterwurzacher
Copy-paste error. https://github.com/rfjakob/gocryptfs/issues/308
2019-01-02fusefrontend: xattr: fix operations on files without read permissionsJakob Unterwurzacher
* listxattr is fixed via the /proc/self/fd trick * setxattr,removexattr are fixed by opening the file O_WRONLY Fixes https://github.com/rfjakob/gocryptfs/issues/308
2019-01-02fusefrontend: use Fsetxattr/Fgetxattr/etc on all platformsJakob Unterwurzacher
Darwin now also has these functions, use them. Simplifies the code and makes it symlink-safe on Darwin as well.
2019-01-01fusefrontend: make ListXAttr symlink-safe on LinuxJakob Unterwurzacher
Uses /proc/self/fd.
2019-01-01fusefrontend: make RemoveXAttr() symlink-safeJakob Unterwurzacher
Uses /proc/self/fd on Linux.
2019-01-01fusefrontend: make SetXAttr() symlink-safe on LinuxJakob Unterwurzacher
Uses the /proc/self/fd trick.
2019-01-01fusefrontend: make GetXAttr() symlink-safe on LinuxJakob Unterwurzacher
Uses the /proc/self/fd trick, which does not work on Darwin.
2019-01-01fusefrontend: mark Truncate, Unlink, Symlink symlink-safeJakob Unterwurzacher
No changes needed.
2019-01-01nametransform: rename WriteLongName() -> WriteLongNameAt()Jakob Unterwurzacher
And also rename DeleteLongName() -> DeleteLongNameAt(). The naming follow the names open the openat() etc syscalls.
2019-01-01fusefrontend: mark a few more functions as symlink-safe / unsafeJakob Unterwurzacher
2019-01-01fusefrontend: mark symlink-safe FUSE callsJakob Unterwurzacher
Document which FUSE calls are already symlink-safe in the function comment.
2018-07-01fsck: rename "CorruptItems" channel to "MitigatedCorruptions"Jakob Unterwurzacher
Make it clear that this channel is only used to report corruptions that are transparently mitigated and do not return an error to the user.
2018-06-19Fix three golint warningsJakob Unterwurzacher
We are clean again. Warnings were: internal/fusefrontend/fs.go:443:14: should omit type string from declaration of var cTarget; it will be inferred from the right-hand side internal/fusefrontend/xattr.go:26:1: comment on exported method FS.GetXAttr should be of the form "GetXAttr ..." internal/syscallcompat/sys_common.go:9:7: exported const PATH_MAX should have comment or be unexported
2018-06-12xattr: return EOPNOTSUPP instead of ENODATA in GetXattrJakob Unterwurzacher
Reading system.posix_acl_access and system.posix_acl_default should return EOPNOTSUPP to inform user-space that we do not support ACLs. xftestest essientially does chacl -l | grep "Operation not supported" to determine if the filesystem supports ACLs, and used to wrongly believe that gocryptfs does.
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.
2018-05-15xattr: 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.
2018-05-10xattr: 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.
2018-05-07xattr: added passing of a "flags" parameterBolshevik
Pass the "flags" parameter to the lower layer syscall. This makes Apple applications being able to successfully save data.
2018-05-01fusefrontend: xattr: return ENOSYS on unsupported flagsJakob Unterwurzacher
We previously returned EPERM to prevent the kernel from blacklisting our xattr support once we get an unsupported flag, but this causes lots of trouble on MacOS: Cannot save files from GUI apps, see https://github.com/rfjakob/gocryptfs/issues/229 Returning ENOSYS triggers the dotfiles fallback on MacOS and fixes the issue.
2018-04-17Improved xattr handling on non-linux systems (#227)bolshevik
* Fixed xattr filtering for MacOS. "system." and "user." prefixes are only relevant for Linux. * Small cleanup and additional tests.
2018-04-03fsck: report skipped corrupt filesJakob Unterwurzacher
OpenDir and ListXAttr skip over corrupt entries, readFileID treats files the are too small as empty. This improves usability in the face of corruption, but hides the problem in a log message instead of putting it in the return code. Create a channel to report these corruptions to fsck so it can report them to the user. Also update the manpage and the changelog with the -fsck option. Closes https://github.com/rfjakob/gocryptfs/issues/191
2018-04-02fusefrontend: xattr: return ENODATA for security.* and system.*Jakob Unterwurzacher
"ls -l" queries security.selinux, system.posix_acl_access, system.posix_acl_default and throws error messages if it gets something else than ENODATA.
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.
2018-03-25fusefrontend: add xattr supportJakob Unterwurzacher
At the moment, only for reverse mode. https://github.com/rfjakob/gocryptfs/issues/217
