532 * The fsp flags "is_pathref" and "is_fsa"
533 * =======================================
538 * The flag "is_pathref" is a property of the low-level VFS-layer file
539 * handle. If "is_pathref" is true, only a subset of VFS calls are allowed
540 * on the handle and on systems that support it, the low-level fd is open
541 * with O_PATH. If "is_pathref" is false, the low-level fd is a "normal"
542 * file descriptor that can be used with all VFS calls.
544 * The flag "is_fsa" is a property of the FSA layer in Samba. The term FSA
545 * layer refers to the parts of smbd that implement Windows NTFS semantics
546 * on-top of a POSIX filesystem. If "is_fsa" is true, the fsp was
547 * processed by the SMB_VFS_CREATE_FILE() VFS call, otherwise the fsp was
548 * created by openat_pathref_fsp() which only connected the low-level
549 * handle by calling into VFS SMB_VFS_OPENAT(), but the whole FSA layer
552 * Note that only three possible combinations of "is_pathref" and "is_fsa"
555 * | is_fsa \ is_pathref | + | - |
556 * |---------------------+---+---|
560 * So a fsp can't be a full low-level fd (is_pathref=false) and not be
561 * processed by the FSA layer.
566 * On Linux the O_PATH flag to open() can be used to open a filehandle on
567 * a file or directory with interesting properties:
569 * - the file-handle indicates a location in the filesystem tree,
570 * - no permission checks are done by the kernel and
571 * - only operations that act purely at the file descriptor level are
574 * The file itself is not opened, and other file operations (e.g.,
575 * read(2), write(2), fchmod(2), fchown(2), fgetxattr(2), ioctl(2),
576 * mmap(2)) fail with the error EBADF.
578 * The following subset of operations that is relevant to Samba is allowed:
581 * - fchdir(2), if the file descriptor refers to a directory,
584 * - passing the file descriptor as the dirfd argument of openat() and the
585 * other "*at()" system calls. This includes linkat(2) with
586 * AT_EMPTY_PATH (or via procfs using AT_SYMLINK_FOLLOW) even if the
587 * file is not a directory.
589 * Opening a file or directory with the O_PATH flag requires no
590 * permissions on the object itself (but does require execute permission
591 * on the directories in the path prefix). By contrast, obtaining a
592 * reference to a filesystem object by opening it with the O_RDONLY flag
593 * requires that the caller have read permission on the object, even when
594 * the subsequent operation (e.g., fchdir(2), fstat(2)) does not require
595 * read permission on the object. [1]
597 * If for example Samba receives an SMB request to open a file requesting
598 * SEC_FILE_READ_ATTRIBUTE access rights because the client wants to read
599 * the file's metadata from the handle, Samba will have to call POSIX
600 * open() with at least O_RDONLY access rights.
602 * Usecase for O_PATH in Samba
603 * ---------------------------
605 * By leveraging this Linux specific flags we can avoid permission
606 * mismatches as described above. Additionally O_PATH allows basing all
607 * filesystem accesses done by the fileserver on handle based syscalls by
608 * opening all client pathnames with O_PATH and consistently using for
609 * example fstat() instead of stat() throughout the codebase.
611 * Subsequently we will refer to Samba file-handles (fsp's) opened with
612 * O_PATH "path referencing fsp's" or "pathref" fsp's for short.
614 * Currently Samba bases the decision whether to call POSIX open() on a
615 * client pathname or whether to leave the low-level handle at -1, what we
616 * call a stat-open, in the function open_file() and it is based on the
617 * client requested SMB acccess mask.
619 * The set of rights that trigger an open() include READ_CONTROL_ACCESS,
620 * resulting in a call to open() with at least O_RDONLY. If the filesystem
621 * supports NT style ACLs natively (like GPFS or ZFS), the filesystem may
622 * grant the user requested right READ_CONTROL_ACCESS, but it may not
623 * grant READ_DATA (O_RDONLY), resulting in a permission denied error.
625 * Historically the set of access rights that triggered opening a file was:
633 * SEC_FLAG_SYSTEM_SECURITY
634 * READ_CONTROL_ACCESS
636 * By using O_PATH this can be trimmed down to
643 * Fallback on systems without O_PATH support
644 * ------------------------------------------
646 * A fallback is needed that allows opening a file-handle with the same
647 * higher level semantics even if the system doesn't support O_PATH. This
648 * is implemented by impersonating the root user for the open()
649 * syscall. To avoid bypassing restrictive permissions on intermediate
650 * directories components of a path, the root user is only impersonated
651 * after changing directory to the parent directory of the client
652 * requested pathname.
654 * In order to avoid privilege escalation security issues with these root
655 * opened file-handles we must carefully control their usage throughout
656 * the codebase. Therefore we
658 * - tag the pathref fsp's with the flag "is_pathref" and
660 * - control access to the file-handle by making the structure private and only
661 * allowing access with accessor functions.
663 * Two functions are used to fetch the low-level system file-handle from an fsp
665 * - fsp_get_io_fd(fsp): enforces fsp is NOT a pathref file-handle and
667 * - fsp_get_pathref_fd(fsp): allows fsp to be either a pathref file-handle or a
668 * traditional POSIX file-handle opened with O_RDONLY or any other POSIX open
671 * The general guideline when to use which function is:
673 * - if you do something like fstat(fd), use fsp_get_pathref_fd(fsp),
674 * - if you do something like *at(dirfd, ...), use fsp_get_pathref_fd(fsp),
675 * - if you want to print the fd for example in DEBUG messages, use
676 * fsp_get_pathref_fd(fsp),
677 * - if you want to call close(fd), use fsp_get_pathref_fd(fsp),
678 * - if you're doing a logical comparison of fd values, use
679 * fsp_get_pathref_fd().
681 * In any other case use fsp_get_io_fd().
