* The fsp flags "is_pathref" and "is_fsa"
|
||
* =======================================
|
||
*
|
||
* Summary
|
||
* -------
|
||
*
|
||
* The flag "is_pathref" is a property of the low-level VFS-layer file
|
||
* handle. If "is_pathref" is true, only a subset of VFS calls are allowed
|
||
* on the handle and on systems that support it, the low-level fd is open
|
||
* with O_PATH. If "is_pathref" is false, the low-level fd is a "normal"
|
||
* file descriptor that can be used with all VFS calls.
|
||
*
|
||
* The flag "is_fsa" is a property of the FSA layer in Samba. The term FSA
|
||
* layer refers to the parts of smbs that implement Windows NTFS semantics
|
||
* on-top of a POSIX filesystem. If "is_fsa" is true, the fsp was
|
||
* processed by the SMB_VFS_CREATE_FILE() VFS call, otherwise the fsp was
|
||
* created by openat_pathref_fsp() which only connected the low-level
|
||
* handle by calling into VFS SMB_VFS_OPENAT(), but the whole FSA layer
|
||
* logic is skipped.
|
||
*
|
||
* Note that only three possible combinations of "is_pathref" and "is_fsa"
|
||
* are possible:
|
||
*
|
||
* | is_fsa \ is_pathref | + | - |
|
||
* |---------------------+---+---|
|
||
* | + | + | + |
|
||
* | - | + | - |
|
||
*
|
||
* So a fsp can't be a full low-level fd (is_pathref=false) and not be
|
||
* processed by the FSA layer.
|
||
*
|
||
* Details
|
||
* -------
|
||
*
|
||
* On Linux the O_PATH flag to open() can be used to open a filehandle on
|
||
* a file or directory with interesting properties:
|
||
*
|
||
* - the file-handle indicates a location in the filesystem tree,
|
||
* - no permission checks are done by the kernel and
|
||
* - only operations that act purely at the file descriptor level are
|
||
* allowed.
|
||
*
|
||
* The file itself is not opened, and other file operations (e.g.,
|
||
* read(2), write(2), fchmod(2), fchown(2), fgetxattr(2), ioctl(2),
|
||
* mmap(2)) fail with the error EBADF.
|
||
*
|
||
* The following subset of operations that is relevant to Samba is allowed:
|
||
*
|
||
* - close(2),
|
||
* - fchdir(2), if the file descriptor refers to a directory,
|
||
* - fstat(2),
|
||
* - fstatfs(2) and
|
||
* - passing the file descriptor as the dirfd argument of openat() and the
|
||
* other "*at()" system calls. This includes linkat(2) with
|
||
* AT_EMPTY_PATH (or via procfs using AT_SYMLINK_FOLLOW) even if the
|
||
* file is not a directory.
|
||
*
|
||
* Opening a file or directory with the O_PATH flag requires no
|
||
* permissions on the object itself (but does require execute permission
|
||
* on the directories in the path prefix). By contrast, obtaining a
|
||
* reference to a filesystem object by opening it with the O_RDONLY flag
|
||
* requires that the caller have read permission on the object, even when
|
||
* the subsequent operation (e.g., fchdir(2), fstat(2)) does not require
|
||
* read permis‐ sion on the object. [1]
|
||
*
|
||
* If for example Samba receives an SMB request to open a file requesting
|
||
* SEC_FILE_READ_ATTRIBUTE access rights because the client wants to read
|
||
* the file's metadata from the handle, Samba will have to call POSIX
|
||
* open() with at least O_RDONLY access rights.
|
||
*
|
||
* Usecase for O_PATH in Samba
|
||
* ---------------------------
|
||
*
|
||
* By leveraging this Linux specific flags we can avoid permission
|
||
* mismatches as described above. Additionally O_PATH allows basing all
|
||
* filesystem accesses done by the fileserver on handle based syscalls by
|
||
* opening all client pathnames with O_PATH and consistently using for
|
||
* example fstat() instead of stat() throughout the codebase.
|
||
*
|
||
* Subsequently we will refer to Samba file-handles (fsp's) opened with
|
||
* O_PATH "path referencing fsp's" or "pathref" fsp's for short.
|
||
*
|
||
* Currently Samba bases the decision whether to call POSIX open() on a
|
||
* client pathname or whether to leave the low-level handle at -1, what we
|
||
* call a stat-open, in the function open_file() and it is based on the
|
||
* client requested SMB acccess mask.
|
||
*
|
||
* The set of rights that trigger an open() include READ_CONTROL_ACCESS,
|
||
* resulting in a call to open() with at least O_RDONLY. If the filesystem
|
||
* supports NT style ACLs natively (like GPFS or ZFS), the filesystem may
|
||
* grant the user requested right READ_CONTROL_ACCESS, but it may not
|
||
* grant READ_DATA (O_RDONLY), resulting in a permission denied error.
|
||
*
|
||
* Historically the set of access rights that triggered opening a file was:
|
||
*
|
||
* FILE_READ_DATA
|
||
* FILE_WRITE_DATA
|
||
* FILE_APPEND_DATA
|
||
* FILE_EXECUTE
|
||
* WRITE_DAC_ACCESS
|
||
* WRITE_OWNER_ACCESS
|
||
* SEC_FLAG_SYSTEM_SECURITY
|
||
* READ_CONTROL_ACCESS
|
||
*
|
||
* By using O_PATH this can be trimmed down to
|
||
*
|
||
* FILE_READ_DATA
|
||
* FILE_WRITE_DATA
|
||
* FILE_APPEND_DATA
|
||
* FILE_EXECUTE
|
||
*
|
||
* Fallback on systems without O_PATH support
|
||
* ------------------------------------------
|
||
*
|
||
* A fallback is needed that allows opening a file-handle with the same
|
||
* higher level semantics even if the system doesn't support O_PATH. This
|
||
* is implemented by qimpersonating the root user for the open()
|
||
* syscall. To avoid bypassing restrictive permissions on intermediate
|
||
* directories components of a path, the root user is only impersonated
|
||
* after changing directory to the parent directory of the client
|
||
* requested pathname.
|
||
*
|
||
* In order to avoid privilege escalation security issues with these root
|
||
* opened file-handles we must carefully control their usage throughout
|
||
* the codebase. Therefor we
|
||
*
|
||
* - tag the pathref fsp's with the flag "is_pathref" and
|
||
*
|
||
* - control access to the file-handle by making the structure private and only
|
||
* allowing access with accessor functions.
|
||
*
|
||
* Two functions are used to fetch the low-level system file-handle from an fsp
|
||
*
|
||
* - fsp_get_io_fd(fsp): enforces fsp is NOT a pathref file-handle and
|
||
*
|
||
* - fsp_get_pathref_fd(fsp): allows fsp to be either a pathref file-handle or a
|
||
* traditional POSIX file-handle opened with O_RDONLY or any other POSIX open
|
||
* flag.
|
||
*
|
||
* The general guideline when to use which function is:
|
||
*
|
||
* - if you do something like fstat(fd), use fsp_get_pathref_fd(fsp),
|
||
* - if you do something like *at(dirfd, ...), use fsp_get_pathref_fd(fsp),
|
||
* - if you want to print the fd for example in DEBUG messages, use
|
||
* fsp_get_pathref_fd(fsp),
|
||
* - if you want to call close(fd), use fsp_get_pathref_fd(fsp),
|
||
* - if you're doing a logical comparison of fd values, use
|
||
* fsp_get_pathref_fd().
|
||
*
|
||
* In any other case use fsp_get_io_fd().
