Functions

func Dup3

func Dup3(oldfd int, newfd int, flags int) (err error)

Dup3 is not available on Darwin, so we use Dup2 instead.

func EnospcPrealloc

func EnospcPrealloc(fd int, off int64, len int64) error

Sorry, fallocate is not available on OSX at all and fcntl F_PREALLOCATE is not accessible from Go. See https://github.com/rfjakob/gocryptfs/issues/18 if you want to help.

func Faccessat

func Faccessat(dirfd int, path string, mode uint32) error

Faccessat exists both in Linux and in MacOS 10.10+, but the Linux version DOES NOT support any flags. Emulate AT_SYMLINK_NOFOLLOW like glibc does.

func Fallocate

func Fallocate(fd int, mode uint32, off int64, len int64) error

See above.

func Fchmodat

func Fchmodat(dirfd int, path string, mode uint32, flags int) (err error)

func Fchownat

func Fchownat(dirfd int, path string, uid int, gid int, flags int) (err error)

func Fstatat

func Fstatat(dirfd int, path string, stat *unix.Stat_t, flags int) (err error)

func Getdents

func Getdents(fd int) ([]fuse.DirEntry, error)

func Linkat

func Linkat(olddirfd int, oldpath string, newdirfd int, newpath string, flags int) (err error)

Linkat exists both in Linux and in MacOS 10.10+.

func Mkdirat

func Mkdirat(dirfd int, path string, mode uint32) (err error)

func Mknodat

func Mknodat(dirfd int, path string, mode uint32, dev int) (err error)

func OpenNofollow

func OpenNofollow(baseDir string, relPath string, flags int, mode uint32) (fd int, err error)

OpenNofollow opens the file/dir at "relPath" in a way that is secure against symlink attacks. Symlinks that are part of "relPath" are never followed. This function is implemented by walking the directory tree, starting at "baseDir", using the Openat syscall with the O_NOFOLLOW flag. Symlinks that are part of the "baseDir" path are followed.

func Openat

func Openat(dirfd int, path string, flags int, mode uint32) (fd int, err error)

func Readlinkat

func Readlinkat(dirfd int, path string) (string, error)

Readlinkat exists both in Linux and in MacOS 10.10+. We may add an emulated version for users on older MacOS versions if there is demand. Buffer allocation is handled internally, unlike the bare unix.Readlinkat.

func Renameat

func Renameat(olddirfd int, oldpath string, newdirfd int, newpath string) (err error)

func Symlinkat

func Symlinkat(oldpath string, newdirfd int, newpath string) (err error)

func Unix2syscall

func Unix2syscall(u unix.Stat_t) syscall.Stat_t

Unix2syscall converts a unix.Stat_t struct to a syscall.Stat_t struct.

func Unlinkat

func Unlinkat(dirfd int, path string, flags int) (err error)
