Authenticated disk encryption is experimentally supported by cryptsetup
since v2.0.0 and allows for automatic dm-integrity setup for LUKS
devices. Add support for the mode to systemd-repart. The PR adds support
for `cryptsetup luksFormat --integrity` to systemd-repart and
"encryptedwithintegrity" dissection policy.
Limitations:
- No discard, online-only mode for repart.
Closes#39250
The unix-domain socket to AF_VSOCK multiplexers in Firecracker and
vhost-device-vsock sends OK PORT response to the client, resulting
ssh clients to abort the connection with the additional response. This
patch addresses this issue by waiting and expecting the possible OK PORT
response from the multiplexer, if any, and then handover the socket fd
to the ssh client. It only checks if the response begins with OK and
consume the response till the first \n, for simplicity.

When a Yubikey or other fido2 device has FIPS mode enabled, UV will
always be required and cannot be disabled. Unhelpfully, when it is not
sent down, the hardware token (not the library) returns a generic
FIDO_ERR_MISSING_PARAMETER:
$ systemd-cryptenroll --fido2-device=auto --fido2-with-client-pin=no foo
<...>
libfido2: rx: payload_len=1
libfido2: fido_rx: buf=0x55c9ce170940, len=1
libfido2: 0000: 14
libfido2: cbor_parse_reply: blob[0]=0x14
libfido2: fido_dev_get_assert_rx: adjust_assert_count
Failed to ask token for assertion: FIDO_ERR_MISSING_PARAMETER
This can be set even when the token doesn't support UV (as in, fingerprint
reader), in which case using the PIN is required.
Check if 'alwaysUv' is set, and if not already configured, force
either UV (if available) or PIN when enrolling.
Now that we have Management Component Transport Protocol (MCTP) transports
available over USB, it would be helpful to apply udev's persistent
naming rules to MCTP interfaces, to follow the USB hub/port topology.
Enable persistent naming for ARPHRD_MCTP-type devices, using a "mc" name
prefix, and add appropriate definitions for the v260 naming sheme.
Adds a new `SYSTEMD_NSS_RESOLVE_INTERFACE` environment variable to the nss-resolve module, whose value is subsequently passed down to the `ifindex` resolved lookup option.
This allows name lookups to be constrained to a just single interface for e.g. captive portal browsers.
This allows us to query the window size without moving the cursor. We have
various reports about the cursor being in an unexpected position and/or state.

LUKS2 supports built-in integrity checking which may come very handy to
mitigate partial rollback attacks on the storage when only some specific
parts are restored to some old encrypted state. Specific use-cases like
Confidential VMs may want to mandate the usage of feature e.g. on the root
volume. Introduce "encryptedwithintegrity" image policy to support that.
Note, due to the current libcryptsetup limitations, checking whether the
feature is enabled or not for the 'file' case (e.g. DDI image as a raw file)
requires setting up a loop device. To avoid that and keep dissect fully
functional when working unpriviliged, implement a minimal custom LUKS header
parser.
Authenticated disk encryption is experimentally supported by cryptsetup since
v2.0.0 and allows for automatic dm-integrity setup for LUKS devices. Add
support for the mode to systemd-repart. Currently, the option can only be used
in 'online' mode as libcryptsetup does not support creating integrity data
without the use of in-kernel dm-integrity infrastructure.
Integrity=/IntegrityAlgorithm= are added in the anticipation of other integrity
protection options, e.g. enabling dm-integrity for a plain unencrypted
partition.

In setup_output() we assume stdout has been set up properly
before stderr, hence the stdout we're inheriting from must
be writable (or more precisely, would have been adjusted to be).
Hence no need to duplicate it.
Note that exec_input_is_inheritable() rightfully refuses EXEC_INPUT_FILE,
in which case std_output would have been reset in service_fix_stdio()
already.
While at it, use the generic fallback logic of first trying user manager
stdout when stdin is not writable.
* Do not interleave root_directory_as_fd with stdio fields
* Do not use different serialization key for different modes
pointing to same path
* Escape stdio file paths (as per

There is currently no way to figure out a rate limit was hit on a unit,
as the last result is stripped in order to keep reporting the first
result, which is useful in case of a watchdog failure, which is the
reason why it was changed as such.
But rate limiting is also an important information to provide to
users, so allow the Result property to reflect it when it
happens.
This can happen expectedly if an addon purely provides .dtbauto
sections, and there's no match for this machine. Reduce the log message
of this case to "debug" level.

This fixes extensions refreshing + verity-protected DDIs.
TEST-50-DISSECT previously passed because confext refreshing
is tested after live mount, the latter of which used to
load libcryptsetup in pid1.

rename() may yield ENOTEMPTY rather than EEXIST for existing dir,
so catch that too. Also, both the source and target must be
writable when exchanging.
Test coverage for this logic (i.e. user units with ExecStartPre=)
will be added later.
While blocking dlopen() in child generally makes sense, it does
also lead to misery - in the very case of extension/cred refreshing
it then enforces loading of libcryptsetup/libacl in pid1, which
are otherwise never used. Let's add a flag to opt out hence, but
still prohibit it in namespace_fork/enter().
