This is a rework of #24764 by Cristian Rodríguez
<crodriguez@owncloud.com>, which stalled.
Instead of assigning -1 we'll use a macro defined to INT_MAX however.
This changes a boolean param into a proper bitflag field.
Given this only defines a single flag for now this doesn't look like
much of an improvement. But we'll add another flag shortly, where it
starts to make more sense.
Add functions to get either the 'legacy' or standard SRK template, for RSA or
ECC. The 'legacy' templates are those used with earlier code, where a transient
key was created to use for tpm sealing; the standard SRK is the persistent
shared key as defined in TCG guidance docs.
This also replaces tpm2_get_primary_template() with the new functions; that
function's use of flags is confusing and unnecessary.
Remove _cleanup_tpm2_context_ and _cleanup_tpm2_handle_ macros, replacing their
use with _cleanup_(tpm2_context_unrefp) and _cleanup_(tpm2_handle_freep),
respectively.
Without this, the tests would generally be skipped, since we haven't made a
release with the addon stub yet. But even if the file is there, we always want
to test the freshly-built item.
This adds tpm2_get_capability_algs(), tpm2_supports_alg(), and
tpm2_test_parms(). These functions allow verifying that the TPM supports
specific algs and parameters.
When creating a new context, this checks if the TPM supports the symmetric algs
we use. If the TPM does not support the symmetric algs and parameters we
require, we log and return error.
No code change, just some splitting out of the relevant code from
udev-util.[ch].
This makes sense on its own, but is also prepartion to move the code
that checks for low battery state into battery-util.[ch], too.
By default, label_ops is initialized with a NULL pointer which translates
to noop labelling operations. In mac_selinux_init() and the new mac_smack_init(),
we initialize label_ops with a MAC specific LabelOps pointer.
We also introduce mac_init() to initialize any configured MACs and replace all
usages of mac_selinux_init() with mac_init().
In test-execute, only the unit was started, not the slice. Because of
that the slice cgroup was pruned even if it was still needed. From what
I can tell, this is because, in the test, we don't have all the
mechanics that starts the slice for a service. To fix the issue the
slice is started manually.
This adds functions to get the digest for a PolicyAuthorize operation. For
building a policy hash, this provides a function to calculate the hash; and for
building a policy hash to satisfy the authPolicy for an existing object, this
provides a function to perform PolicyAuthorize with an existing session.
This adds functions to get the digest for a PolicyAuthValue operation. For
building a policy hash, this provides a function to calculate the hash; and for
building a policy hash to satisfy the authPolicy for an existing object, this
provides a function to perform PolicyAuthValue with an existing session.
This adds functions to get the digest for a PolicyPCR operation. For building
a policy hash, this provides a function to calculate the hash; and for building
a policy hash to satisfy the authPolicy for an existing object, this provides a
function to perform PolicyPCR with an existing session.
This adds functions to get the "name" of a key. The key "name", as defined
by the TPM2 spec, includes its entire public area (with attribute fields),
not only its key fingerprint.
A function is added to calculate the name of a provided key public area,
as well as a function to get the name of a key which is present in the TPM.
These functions allow extending (or initializing) a TPM2B_DIGEST with additional
data, using a specified hash operation. This is needed to perform hash
calculations instead of relying on the TPM to perform the calculations in
trial sessions.
Recent gcc versions have started to trigger false positive
maybe-uninitialized warnings. Let's make sure we initialize
variables annotated with _cleanup_ to avoid these.
