Author: Jeremy Allison <j...@samba.org>
Date: Mon Dec 14 12:07:48 2020 -0800
smbd: smb_info_set_ea() can only get fsp==NULL in POSIX mode accessing a
symlink.
Ensure this is the case and force-return NT_STATUS_ACCESS_DENIED here.
Remove any race condition if anyone modifies the symlink whilst the
operation is in process.
This now allows us to require a valid fsp for operations on EAs.

vfs: SMB_VFS_GET_COMPRESSION() -> SMB_VFS_FGET_COMPRESSION()
Now that handle based fdos_mode() is used everywhere we can be sure that
we're
also always getting a handle in SMB_VFS_GET_COMPRESSION() so we can now
safely
remove the path parameter. :)

smbd: use fsp in smb_set_file_time()
Ensure we have a valid fsp whos name we pass to file_ntimes(). Remember,
file_ntimes() by default ends up calling SMB_VFS_GET_DOS_ATTRIBUTES() under
the
hood in order to get/set the creation date.
As any fsp->fsp_name contains a backpointer to the fsp ie
fsp->fsp_name->fsp == fsp
passing set_fsp->fsp_name to file_ntimes() allows replacing the path based
SMB_VFS_GET_DOS_ATTRIBUTES() with SMB_VFS_FGET_DOS_ATTRIBUTES() under the
hoods.
Also use the base_fsp->fsp_name for the base name in case of setting the
timestamps on a stream.

vfs: Add dirfsp arg to SMB_VFS_READDIR()
This allows for optimisations in VFS module: by passing the dirfsp as an
additional arg, the function can check fsp->fsp_name->flags which may
include eg
SMB_FILENAME_POSIX_PATH to trigger POSIX pathname processing.

smbd: use vfs_stat() in more places
This replaces the code in a bunch of places where we choose between stat()
and
lstat() based on req->posix_pathname. The new code inside vfs_stat() is
based on
checking the smb_fname flag SMB_FILENAME_POSIX_PATH.
req->posix_pathname is inherited from the global POSIX pathnames state and
the
smb_fname flags is also inherited from that indirectly via the UCF flags.
Tl;dr: no change in behaviour. :)

smbd: use vfs_stat() in dptr_ReadDirName()
This is subtle: we inherit the smb_fname flags from the directory to its
directory entries while listing a directory. This means if were listing a
directory in POSIX context, we now treat all entries as POSIX paths and
correctly call lstat() on the entries instead of stat().

smbd: optimisation using pathref fd to open real fd if possible
This is an optimisation that avoids going through the expensive
non_widelink_open() logic a second time. It depends on a usable
/proc/%d/fd/%d
filesystem and this is checked and set as "can_reopen" flag by the VFS in
the
openat() function in the fsp.

vfs_xattr_tdb: don't leak the fd into the caller
This is subtle: generally fsp_set_fd(fd) is called in the caller of
SMB_VFS_OPENAT() in non_widelink_open().
fsp_set_fd() has a check that asserts certain combindations of the existing
fsp->fh->fd and the new fd. Both being valid fds is not allowed.
Therefor inside the VFS we must reset fsp->fh->fd if we've set it.

smbd: reuse smb_fname->fsp in create_file_default()
This is the big bang for the internal pathref fsps: up to this point the
pathref
fsps were lingering around unused inside smb_fname->fsp.
With this change, the internal fsp will be the one that is going to be
returned
from SMB_VFS_CREATE_FILE() if the client requested access mask matches the
criteria in open_file():
uint32_t need_fd_mask =
FILE_READ_DATA |
FILE_WRITE_DATA |
FILE_APPEND_DATA |
FILE_EXECUTE |
WRITE_DAC_ACCESS |
WRITE_OWNER_ACCESS |
SEC_FLAG_SYSTEM_SECURITY |
READ_CONTROL_ACCESS;
As long as the client doesn't request any of the access rights listed
above, we
reuse the smb_fname->fsp, otherwise we close the smb_fname->fsp and call
fd_open() to open a new fsp.
In the future we can remove the four non-IO related access rights from the
list:
WRITE_DAC_ACCESS |
WRITE_OWNER_ACCESS |
SEC_FLAG_SYSTEM_SECURITY |
READ_CONTROL_ACCESS

This ensures that fsp->fsp_name->fsp is again set to the fsp and also
preserves
the link fsp->fsp_name->fsp_link.

smbd: add openat_pathref_fsp()
open_pathref_fsp() opens an "embedded" fsp inside smb_fname as
smb_fname->fsp. We call such an fsp a "pathref" fsp.
On system that support O_PATH the low level openat() is done with O_PATH. On
systems that lack support for O_PATH, we impersonate the root user as a
fallback.
Setting "is_pathref" in the fsp_flags before calling fd_openat() is what
triggers the special low-level behaviour inside the VFS.
The use of pathref fsps allows updating all callers of path based VFS
functions
like
dos_mode(smb_fname)
-> SMB_VFS_GET_DOS_ATTRIBUTES(smb_fname)
-> SMB_VFS_GETXATTR(smb_fname)
to use the handle based VFS function like
fdos_mode(smb_fname->fsp)
-> SMB_VFS_FGET_DOS_ATTRIBUTES(fsp)
-> SMB_VFS_FGETXATTR(fsp)

So it's also safe to use a root opened pathref fd, as the root open is done

still
impersonating the use. Qed.

fsp_get_pathref_fd() in these cases.

smbd: use fsp_get_io_fd() when accessing a file or it's associated metadata
In all places where we access or modify a file or it's associated metadata,
we
use fsp_get_io_fd() to fetch the low-level fd from the fsp. This ensures we
don't accidentally use a pathref fsp where the fd would be opened as root on
systems lacking O_PATH.

CI: skip kernel-oplocks tests on older kernels
The kernel of the gitlab shared runners container host has a bug in the
interaction between kernel oplocks and O_PATH opens which was fixed by
387e3746d01c34457d6a73688acd90428725070b in 5.3.1:
<https://kernel.googlesource.com/pub/scm/linux/kernel/git/jlayton/linux/+/refs/tags/locks-v5.3-1%5E%21/>
Don't actually start the OPLOCK5 test is kernel oplocks are not available,
instead of relying on the #ifdef HAVE_KERNEL_OPLOCKS_LINUX magic in
torture.c.

+ * 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),
