Add function to calculate the hash digest for a provided pin, and also verify
that the final byte in the digest is not 0. This is required because the TPM
will always remove all trailing 0's from an auth value before using it.
Fixes: #27716
Older code did not save the pcr bank (i.e. pcr hash algorithm), and instead let
tpm2_unseal() find the best pcr bank to use. In commit
2cd9d57548 we changed tpm2_unseal() to no longer
handle an unset pcr bank. This adds back in the handling of an unset pcr_bank
so older sealed data should continue to work.
In #20155, verify_shutdown_creds() needs to authenticate for both
org.freedesktop.login1.hibernate-multiple-sessions and
org.freedesktop.login1.hibernate-ignore-inhibit . Previously, the second
authentication attempt would fail with -ESTALE.
Fixes#20155.
This allows using it with CLEANUP_ARRAY(). For the 2 call sites
where we don't need to free the array, we do a regular for loop
calling json_variant_unref() instead.
We have this very similar code in various places, and it#s not entirely
obvious (since we want a prolonged timeout for the reload), hence unify
this at one place.
When this option is set to direct, the service restarts without entering a failed
state. Dependent units are not notified of transitory failure.
This is useful for the following use case:
We have a target with Requires=my-service, After=my-service.
my-service.service is a oneshot service and has Restart=on-failure in
its definition.
my-service.service can get stuck for various reasons and time out, in
which case it is restarted. Currently, when it fails the first time, the
target fails, even though my-service is restarted.
The behavior we're looking for is that until my-service is not restarted
anymore, the target stays pending waiting for my-service.service to
start successfully or fail without being restarted anymore.
The article "a" goes before consonant sounds and "an" goes before vowel
sounds. This commit changes an to a for UKI, UDP, UTF-8, URL, UUID, U-Label, UI
and USB, since they start with the sound /ˌjuː/.
quality_check_password() used to return the same value 0 in two
different cases: when pwq_allocate_context() failed with a
ERRNO_IS_NOT_SUPPORTED() code, and when pwquality_check() rejected the
password. As result, users of quality_check_password() used to report
password weakness also in case when the underlying library was not
available.
Fix this by changing quality_check_password() to forward the
ERRNO_IS_NOT_SUPPORTED() code to its callers, and change the callers
to handle this case gracefully.
