Functions ¶
func DirSeek ¶
DirSeek tests that seeking on a directory works for https://github.com/4831c0/go-fuse/issues/344 .
Go port of xfstests generic/257.
Hint: $ go test ./fs -run TestPosix/DirSeek -v
func FallocateKeepSize ¶
func FcntlFlockLocksFile ¶
func FcntlFlockSetLk ¶
func FstatDeleted ¶
FstatDeleted is similar to NlinkZero, but Fstat()s multiple deleted files in random order and checks that the results match an earlier Stat().
Excercises the fd-finding logic in rawBridge.GetAttr.
func LinkUnlinkRename ¶
LinkUnlinkRename implements rename with a link/unlink sequence
func LseekEnxioCheck ¶
func LseekHoleSeeksToEOF ¶
func MkdirRmdir ¶
func OpenSymlinkRace ¶
Test if Open() is vulnerable to symlink-race attacks using two goroutines:
goroutine "shuffler": In a loop: * Replace empty file "OpenSymlinkRace" with a symlink pointing to /etc/passwd * Replace back with empty file
goroutine "opener": In a loop: * Open "OpenSymlinkRace" and call Fstat on it. Now there's three cases:
- Size=0: we opened the empty file created by shuffler. Normal and uninteresting.
- Size>0 but Dev number different: we (this test) opened /etc/passwd ourselves because we resolved the symlink. Normal.
- Size>0 and Dev number matches the FUSE mount: go-fuse opened /etc/passwd. The attack has worked.
func ParallelFileOpen ¶
func ReadDir ¶
ReadDir creates 110 files one by one, checking that we get the expected entries after each file creation.
func ReadDirConsistency ¶
Creates files, read them back using readdir
func RenameOpenDir ¶
func SetattrSymlink ¶
func SymlinkReadlink ¶
SymlinkReadlink tests basic symlink functionality
func TruncateFile ¶
func TruncateNoFile ¶
