Add a reference configuration with most symmetric cryptographic
algorithms enabled, but without any asymmetric cryptography. This
checks that we don't have spurious unexpected dependencies on
asymmetric-only modules such as bignum.
Keep HAVE_ASM disabled because it's platform-specific.
Keep HAVEGE disabled because it's untested and not recommended.
Keep MEMORY_BUFFER_ALLOC out because it isn't related to cryptography
at all and it makes memory sanitizers ineffective.
Keep THREADING disabled because it requires special build options.
To help the build system find the correct include files, paths starting
with "mbedtls/" or "psa/" must be used. Otherwise, you can run into
build failures like the following when building Mbed Crypto as a
submodule.
In file included from chachapoly.c:31:0:
../../include/mbedtls/chachapoly.h:43:10: fatal error: poly1305.h: No such file or directory
#include "poly1305.h"
^~~~~~~~~~~~
compilation terminated.
Includes for ALT implementations are not modified, as the alt headers
are provided by system integrators and not Mbed TLS or Mbed Crypto.
Make maintaining config files easier by removing any explicit
ciphersuite lists. These explicit lists are prone to being incomplete as
TLS defines more and more ciphersuites. Rather than try to play catch
up, let's refer to sets of ciphersuites with declarative language.
Remove TLS and NET options from config files and scripts.
Note that this fails check-names.sh because options that TLS and NET
files use are no longer present in config.h.
MBEDTLS_PSA_HAS_ITS_IO is not really useful since it doesn't actually
enable anything except the entropy seed file support, which only
requires the ITS interface and not a native implemetation. Remove it.
Since the ITS API has stabilized and we don't plan to make use of more
than ITS, we don't need an abstraction layer between key storage and
key storage over ITS. Merge the ITS code into the generic storage
module.
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.
Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.
Our default configuration file, include/mbedtls/config.h, should always
match configs/config-psa-crypto.h. It had gotten out of sync, so put it
back into sync.
Copy our include/mbedtls/config.h file, which is our default
configuration, to configs/config-psa-crypto.h, updating what was
previously there to the latest defaults.
Add new functions, psa_load_persistent_key(),
psa_free_persistent_key_data(), and psa_save_persistent_key(), for
managing persistent keys. These functions load to or save from our
internal representation of key slots. Serialization is a concern of the
storage backend implementation and doesn't abstraction-leak into the
lifetime management code.
An initial implementation for files is provided. Additional storage
backends can implement this interface for other storage types.
Upstream mbedtls maintains the default configuration in
include/mbedtls/config.h. We maintain the default configuration in
configs/config-default.h, and our PSA-specific configuration in
include/mbedtls/config.h. This means, each time we update Mbed TLS, we need
to update the default configuration file (configs/config-default.h)
manually using the copy from mbedtls.
We failed check-names.sh due to using a define which wasn't described or
defined anywhere. Even though we won't realistically enable
MBEDTLS_PSA_CRYPTO_SPM via the configuration system (and will do it from
PSA Crypto SPM tooling instead), add a description of the configuration to
config.h as good practice. Exclude MBEDTLS_PSA_CRYPTO_SPM from the "full"
configuration as well.
The default config.h omits non-crypto features. Remove some features
that had been accidentally left in but have dependencies that had been
removed.
Also update configs/config-psa-crypto.h to match
include/mbedtls/config.h. They were historically identical but started
diverging when the feature-psa branch was rebased on top of a more
recent upstream.
Now the code builds with the "full" config.
This is useful for testing interop with GnuTLS, which sends records larger
than 512 bytes.
This change is triggered by the addition of CCM interop testing with GnuTLS a
few commits ago.
Conflict: configs/config-picocoin.h was both edited and removed.
Resolution: removed, since this is the whole point of PR #1280 and the
changes in development are no longer relevant.
Enable the MBEDTLS_AES_ROM_TABLES option in the
configs/config-no-entropy.h to place AES lookup tables in ROM. This
saves considerable RAM space, a resource that is very limited in small
devices that use this configuration.
target_config.h is no longer needed for target/platform configurations so
this change removes it from the default and platform configurations for mbed
builds.
