test_psa_constant_names.py was originally written before the split of
crypto.h into crypto_values.h and more, so it now needs to read
crypto_values.h as well.
In both generate_psa_constants.py and test_psa_constant_names.py, read
crypto_extra.h as well. We don't currently define any value there, but
it's plausible that we will one day.
Calls to PSA_ALG_AEAD_WITH_DEFAULT_TAG_LENGTH and
PSA_ALG_FULL_LENGTH_MAC are not in canonical form, so exclude them
from the list of constructor macros to test.
Test psa_constant_names on many inputs. For each input, find out the
numerical value by compiling and running a C program, pass the
numerical value to psa_constant_names and compare the output with the
original input.
Gather inputs by parsing psa/crypto.h and
test_suite_psa_crypto_metadata.data. For macros that take an argument,
list some possible arguments using the parsed data.
Test a few cases. The logic to combine the constraint is similar to
the logic to combine the source and target, so it's ok to have less
parameter domain coverage for constraints.
Split the testing into tests that exercise policies in
test_suite_psa_crypto and tests that exercise slot content (slot
states, key material) in test_suite_psa_crypto_slot_management.
Test various cases of source and target policies with and without
wildcards. Missing: testing of the policy constraint on psa_copy_key
itself.
Test several key types (raw data, AES, RSA). Test with the
source or target being persistent.
Add failure tests (incompatible policies, source slot empty, target
slot occupied).
Remove front matter from our EC key format, to make it just the contents
of an ECPoint as defined by SEC1 section 2.3.3.
As a consequence of the simplification, remove the restriction on not
being able to use an ECDH key with ECDSA. There is no longer any OID
specified when importing a key, so we can't reject importing of an ECDH
key for the purpose of ECDSA based on the OID.
Remove pkcs-1 and rsaEncryption front matter from RSA public keys. Move
code that was shared between RSA and other key types (like EC keys) to
be used only with non-RSA keys.
New function psa_copy_key().
Conflicts:
* library/psa_crypto.c: trivial conflicts due to consecutive changes.
* tests/suites/test_suite_psa_crypto.data: the same code
was added on both sides, but with a conflict resolution on one side.
* tests/suites/test_suite_psa_crypto_metadata.function: the same code
was added on both sides, but with a conflict resolution on one side.
You can use PSA_ALG_ANY_HASH to build the algorithm value for a
hash-and-sign algorithm in a policy. Then the policy allows usage with
this hash-and-sign family with any hash.
Test that PSA_ALG_ANY_HASH-based policies allow a specific hash, but
not a different hash-and-sign family. Test that PSA_ALG_ANY_HASH is
not valid for operations, only in policies.
Test for a subclass of public-key algorithm: those that perform
full-domain hashing, i.e. algorithms that can be broken down as
sign(key, hash(message)).
Remove the type and bits arguments to psa_allocate_key() and
psa_create_key(). They can be useful if the implementation wants to
know exactly how much space to allocate for the slot, but many
implementations (including ours) don't care, and it's possible to work
around their lack by deferring size-dependent actions to the time when
the key material is created. They are a burden to applications and
make the API more complex, and the benefits aren't worth it.
Change the API and adapt the implementation, the units test and the
sample code accordingly.
Change the key derivation API to take inputs in multiple steps,
instead of a single one-site-fits-poorly function.
Conflicts:
* include/psa/crypto.h: merge independent changes in the documentation
of psa_key_agreement (public_key from the work on public key formats
vs general description and other parameters in the work on key derivation).
* tests/suites/test_suite_psa_crypto.data: update the key agreement
tests from the work on key derivation to the format from the work on
public key formats.
* tests/suites/test_suite_psa_crypto_metadata.function: reconcile the
addition of unrelated ALG_IS_xxx macros
Get rid of "key selection" algorithms (of which there was only one:
raw key selection).
Encode key agreement by combining a raw key agreement with a KDF,
rather than passing the KDF as an argument of a key agreement macro.

Wildcard patterns now work with command line COMPONENT arguments
without --except as well as with. You can now run e.g.
`all.sh "check_*` to run all the sanity checks.
After backing up and restoring config.h, `git diff-files` may report
it as potentially-changed because it isn't sure whether the index is
up to date. Use `git diff` instead: it actually reads the file.
Only look for armcc if component_build_armcc is to be executed,
instead of requiring the option --no-armcc.
You can still pass --no-armcc, but it's no longer required when
listing components to run. With no list of components or an exclude
list on the command line, --no-armcc is equivalent to having
build_armcc in the exclude list.
Build the list of components to run in $RUN_COMPONENTS as part of
command line parsing. After parsing the command line, it no longer
matters how this list was built.
Extract the list of available components by looking for definitions of
functions called component_xxx. The previous code explicitly listed
all components in run_all_components, which opened the risk of
forgetting to list a component there.
Add a conditional execution facility: if a function support_xxx exists
and returns false then component_xxx is not executed (except when the
command line lists an explicit set of components to execute).

MAKEFLAGS was set to -j if it was already set, instead of being set if
not previously set as intended. So now all.sh will do parallel builds
if invoked without MAKEFLAGS in the environment.
Don't bail out of all.sh if the OS isn't Linux. We only expect
everything to pass on a recent Linux x86_64, but it's useful to call
all.sh to run some components on any platform.
In all.sh, always run both MemorySanitizer and Valgrind. Valgrind is
slower than ASan and MSan but finds some things that they don't.
Run MSan unconditionally, not just on Linux/x86_64. MSan is supported
on some other OSes and CPUs these days.
Use `all.sh --except test_memsan` if you want to omit MSan because it
isn't supported on your platform. Use `all.sh --except test_memcheck`
if you want to omit Valgrind because it's too slow.
Make the test scripts more portable (tested on FreeBSD): don't insist
on GNU sed, and recognize amd64 as well as x86_64 for `uname -m`. The
`make` utility must still be GNU make.
Call `set disable-randomization off` only if it seems to be supported.
The goal is to neither get an error about disable-randomization not
being supported (e.g. on FreeBSD), nor get an error if it is supported
but fails (e.g. on Ubuntu).
Only fiddle with disable-randomization from all.sh, which cares
because it reports the failure of ASLR disabling as an error. If a
developer invokes the Gdb script manually, a warning about ASLR
doesn't matter.
Use `cmake -D CMAKE_BUILD_TYPE=Asan` rather than manually setting
`-fsanitize=address`. This lets cmake determine the necessary compiler
and linker flags.
With UNSAFE_BUILD on, force -Wno-error. This is necessary to build
with MBEDTLS_TEST_NULL_ENTROPY.

fixed processing of PSA macros in check names script.
This required changes in:
*list-macros.sh to scan the PSA headers
*check-names to scan PSA files and allow PSA_* macro names
Add new initializers for cipher operation objects and use them in our

straightforwardness.
Add new initializers for MAC operation objects and use them in our tests
and library code. Prefer using the macro initializers due to their
straightforwardness.
Add new initializers for hash operation objects and use them in our

Add new initializers for key policies and use them in our docs, example
programs, tests, and library code. Prefer using the macro initializers

Merge the work on all.sh that was done on mbedtls-2.14.0 with the
changes from mbedtls-2.14.0 to the current tip of mbed-crypto/development.
There is a merge conflict in test/scripts/all.sh, which is the only
file that was modified in the all.sh work branch. I resolved it by
taking the copy from the all.sh branch and applying the changes
between mbedtls-2.14.0 and mbedtls-2.16.0. As evidenced by
`git diff mbedtls-2.14.0 d668baebc5e1709f4118aba3802d9af0ee4e4d83`,
many of the commits in
`git log mbedtls-2.14.0 d668baebc5e1709f4118aba3802d9af0ee4e4d83`
cancelled each other or were redundant with parallel commits that had
also occured via another branch included in mbedtls-2.14.0, leaving
the following differences:
* Removal of one unimportant blank line.
* The changes from db2b8db715
"psa: Add storage implementation for files", to turn off
PSA storage when MBEDTLS_FS_IO is turned off, which I manually
replayed.
Merge the work on all.sh that was done on mbedtls-2.14.0 with the
changes from mbedtls-2.14.0 to mbedtls-2.16.0.
There is a merge conflict in test/scripts/all.sh, which is the only
file that was modified in the all.sh work branch. I resolved it by
taking the copy from the all.sh branch and applying the changes
between mbedtls-2.14.0 and mbedtls-2.16.0. These changes consisted of
two commits:
* "Add tests to all.sh for CHECK_PARAMS edge cases": adds two
test components which are reproduced here as
test_check_params_without_platform and component_test_check_params_silent.
* "tests: Backup config.h before modifying it": moot because the
component framework introduced in the all.sh branch backs up config.h
systematically.
In all.sh, always save config.h before running a component, instead of
doing it manually in each component that requires it (except when we
forget, which has happened). This would break a script that requires
config.h.bak not to exist, but we don't have any of those.

Call cleanup from run_component instead of calling it from each
individual component function.
Clean up after each component rather than before. With the new
structure it makes more sense for each component to leave the place
clean. Run cleanup once at the beginning to start from a clean slate.
Move almost all the code of this script into functions. There is no
intended behavior change. The goal of this commit is to make
subsequent improvements easier to follow.
A very large number of lines have been reintended. To see what's going
on, ignore whitespace differences (e.g. diff -w).
I followed the following rules:
* Minimize the amount of code that gets moved.
* Don't change anything to what gets executed or displayed.
* Almost all the code must end up in a function.
* One function does one thing. For most of the code, that's from one
"cleanup" to the next.
* The test sequence functions (run_XXX) are independent.
The change mostly amounts to putting chunks of code into a function
and calling the functions in order. A few test runs are conditional;
in those cases the conditional is around the function call.
Change the way some lines are wrapped to cut at a more logical place.
This commit mainly rewrites multi-line calls to TEST_EQUAL, and also a
few calls to PSA_ASSERT.
This commit is the result of the following command, followed by
reindenting (but not wrapping lines):
perl -00 -i -pe 's/^( *)TEST_ASSERT\(([^;=]*)(?: |\n *)==([^;=]*)\);$/${1}TEST_EQUAL($2,$3);/gm' tests/suites/test_suite_psa_*.function

Cause a compilation error on ARRAY_LENGTH(p) where p is a pointer as
opposed to an array. This only works under GCC and compatible
compilers such as Clang. On other compilers, ARRAY_LENGTH works but
doesn't check the type of its argument.
Document when a context must be initialized or not, when it must be
set up or not, and whether it needs a private key or a public key will
do.
The implementation is sometimes more liberal than the documentation,
accepting a non-set-up context as a context that can't perform the
requested information. This preserves backward compatibility.
The MPI_VALIDATE_RET() macro cannot be used for parameter
validation of mbedtls_mpi_lsb() because this function returns
a size_t.
Use the underlying MBEDTLS_INTERNAL_VALIDATE_RET() insteaed,
returning 0 on failure.
Also, add a test for this behaviour.
For mbedtls_pk_parse_key and mbedtls_pk_parse_keyfile, the password is
optional. Clarify what this means: NULL is ok and means no password.
Validate parameters and test accordingly.
The test that mbedtls_aria_free() accepts NULL parameters
can be performed even if MBEDTLS_CHECK_PARAMS is unset, but
was previously included in the test case aria_invalid_params()
which is only executed if MBEDTLS_CHECK_PARAMS is set.
It's good to make a backup of config.h before modifying it, so that when
"cleanup" runs the next test has a clean default config.h to start from.
Fixes 840af0a9ae ("Add tests to all.sh for CHECK_PARAMS edge cases")
