In preparation for FORTIFY_SOURCE performing compile-time and run-time

avoid intentionally reading across neighboring array fields.
Add a wrapping structure to serve as the memcpy() source, so the compiler
can do appropriate bounds checking, avoiding this future warning:

returns an error without dispatching the requested nvme command. Check

Problem:
On reconfigure of device, there is no way to defend if the backend
storage is matching with the initial backend storage.
Say, if an initial connect request for backend "pool1/image1" got
mapped to /dev/nbd0 and the userspace process is terminated. A next
reconfigure request within NBD_ATTR_DEAD_CONN_TIMEOUT is allowed to
use /dev/nbd0 for a different backend "pool1/image2"
For example, an operation like below could be dangerous:
$ sudo rbd-nbd map --try-netlink rbd-pool/ext4-image
/dev/nbd0
$ sudo blkid /dev/nbd0
/dev/nbd0: UUID="bfc444b4-64b1-418f-8b36-6e0d170cfc04" TYPE="ext4"
$ sudo pkill -9 rbd-nbd
$ sudo rbd-nbd attach --try-netlink --device /dev/nbd0 rbd-pool/xfs-image
/dev/nbd0
$ sudo blkid /dev/nbd0
/dev/nbd0: UUID="d29bf343-6570-4069-a9ea-2fa156ced908" TYPE="xfs"
Solution:
Provide a way for userspace processes to keep some metadata to identify
between the device and the backend, so that when a reconfigure request is
made, we can compare and avoid such dangerous operations.
With this solution, as part of the initial connect request, backend
path can be stored in the sysfs per device config, so that on a reconfigure
request it's easy to check if the backend path matches with the initial
connect backend path.
Please note, ioctl interface to nbd will not have these changes, as there
won't be any reconfigure.

when network connections fail and nodes reconnect. Previously,
this would result in lost messages which could only be handled

Merge tag 'fs.openat2.unknown_flags.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull openat2 fixes from Christian Brauner:
- Remove the unused VALID_UPGRADE_FLAGS define we carried from an
extension to openat2() that we haven't merged. Aleksa might be
getting back to it at some point but just not right now.
- openat2() used to accidently ignore unknown flag values in the upper
32 bits.
The new openat2() syscall verifies that no unknown O-flag values are
set and returns an error to userspace if they are while the older
open syscalls like open() and openat() simply ignore unknown flag
values:
#define O_FLAG_CURRENTLY_INVALID (1 << 31)
struct open_how how = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID,
.resolve = 0,
};
/* fails */
fd = openat2(-EBADF, "/dev/null", &how, sizeof(how));
/* succeeds */
fd = openat(-EBADF, "/dev/null", O_RDONLY | O_FLAG_CURRENTLY_INVALID);
However, openat2() silently truncates the upper 32 bits meaning:
#define O_FLAG_CURRENTLY_INVALID_LOWER32 (1 << 31)
#define O_FLAG_CURRENTLY_INVALID_UPPER32 (1 << 40)
struct open_how how_lowe32 = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_LOWER32,
};
struct open_how how_upper32 = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_UPPER32,
};
/* fails */
fd = openat2(-EBADF, "/dev/null", &how_lower32, sizeof(how_lower32));
/* succeeds */
fd = openat2(-EBADF, "/dev/null", &how_upper32, sizeof(how_upper32));
Fix this by preventing the immediate truncation in build_open_flags()
and add a compile-time check to catch when we add flags in the upper
32 bit range.

Pull device properties framework updates from Rafael Wysocki:
"These unify device properties access in some pieces of code and make
related changes.
Specifics:
- Handle device properties with software node API in the ACPI IORT
table parsing code (Heikki Krogerus).
- Unify of_node access in the common device properties code, constify
the acpi_dma_supported() argument pointer and fix up CONFIG_ACPI=n
stubs of some functions related to device properties (Andy
Shevchenko)"
