Ronald Cron 78a38f607c tls13: srv: Do not use early_data_status
Due to the scope reduction for
mbedtls_ssl_read_early_data(), on
server as early data state variable
we now only need a flag in the
handshake context indicating if
the server has accepted early data
or not.

Ronald Cron 3b9034544e Revert "tls13: Introduce early_data_state SSL context field"
This reverts commit 0883b8b625.
Due to the scope reduction of mbedtls_ssl_read_early_data()
it is not necessary anymore to refine the usage
of early_data_status/state rather the opposite.

Introduce early_data_state SSL context field to
distinguish better this internal state from

Ryan Everett a103ec9ad4 Make one shot operations thread safe
These all follow a pattern of locking some key slot,
reading its contents, and then unregistering from reading the slot.

Ryan Everett c053d968f2 Make psa_destroy_key threadsafe
We do not require linearizability in the case of destroying a key in use.
Using a key and destroying it simultaneously will not cause any issues
as the user will only use the copy of the key in the slot.
Two simulatenous deletion calls to one key cannot interfere, the first caller
sets the slot's state to PENDING_DELETION, the second caller will back off.
Remove outdated comment about one key being in multiple slots, psa_open_key
does not put the key into a new slot.

This function, and mbedtls_psa_crypto_free, are not thread safe as they wipe slots
regardless of state. They are not part of the PSA Crypto API, untrusted applications
cannot call these functions in a crypto service.
In a service intergration, mbedtls_psa_crypto_free on the client cuts the communication
with the crypto service.

Gilles Peskine 9cd2e9ad1b mbedtls_pk_get_psa_attributes: require MBEDTLS_PSA_CRYPTO_C
Ideally this and other pk functions would work with
MBEDTLS_PSA_CRYPTO_CLIENT (i.e. whether PSA API functions are implemented
locally or via client-server communication). However, at the moment, some
helper functions are missing when MBEDTLS_PSA_CRYPTO_C is disabled, at least
mbedtls_ecc_group_to_psa(). For the time being, don't provide
mbedtls_pk_get_psa_attributes() when MBEDTLS_PSA_CRYPTO_C is disabled. We
can improve later, looking generally at a group of functions to generalize,
not mixed with delivering new APIs.

Ryan Everett 1b70a07eca Replace psa_unlock_key_slot calls in operations which act on FULL slots
Replaces calls to psa_unlock_key_slot with calls to psa_unregister_read.

All instances follow a pattern of a call to psa_get_and_lock_key_slot_X,
followed by some code which reads from a slot, followed by a call to psa_unregister_read.

Ryan Everett c70ce576bd Update psa_destroy_key, psa_purge_key and psa_close_key
This does not yet implement destruction while a key is in use for psa_destroy_key;
that will be implemented in a separate pr.
(I am not sure if I am allowed to change the documentation in the include files.)

Ryan Everett 2afb516011 Update and rename psa_get_empty_key_slot
Rename to psa_reserve_free_key_slot, as this function reserves a slot which is
free (not always empty) for filling.
Implement necessary state transitions and state checks.
Rename unlocked_persistent_key_slot to unused_persistent_key_slot.

except for where we do not care about what the state of the slot was before.
