Gilles Peskine cb25cdd53a Add ECDSA tests with hash and key of different lengths
Add some ECDSA test cases where the hash is shorter or longer than the
key length, to check that the API doesn't enforce a relationship
between the two.

For the sign_deterministic tests, the keys are
tests/data_files/ec_256_prv.pem and tests/data_files/ec_384_prv.pem
and the signatures were obtained with Python Cryptodome:

from binascii import hexlify, unhexlify
from Crypto.Hash import SHA256, SHA384
from Crypto.PublicKey import ECC
from Crypto.Signature import DSS
k2 = ECC.import_key(unhexlify("3077020101042049c9a8c18c4b885638c431cf1df1c994131609b580d4fd43a0cab17db2f13eeea00a06082a8648ce3d030107a144034200047772656f814b399279d5e1f1781fac6f099a3c5ca1b0e35351834b08b65e0b572590cdaf8f769361bcf34acfc11e5e074e8426bdde04be6e653945449617de45"))

Gilles Peskine 65fc0686a7 Add tests to ensure that we gather as much entropy as expected
There were tests to ensure that each entropy source reaches its
threshold, but no test that covers the total amount of entropy. Add
test cases with a known set of entropy sources and make sure that we
always gather at least MBEDTLS_ENTROPY_BLOCK_SIZE bytes from a strong
source.

Gilles Peskine 3efcebbc5e SE support: Use a transaction when registering a key
When registering a key in a secure element, go through the transaction
mechanism. This makes the code simpler, at the expense of a few extra
storage operations. Given that registering a key is typically very
rare over the lifetime of a device, this is an acceptable loss.

Drivers must now have a p_validate_slot_number method, otherwise
registering a key is not possible. This reduces the risk that due to a
mistake during the integration of a device, an application might claim
a slot in a way that is not supported by the driver.

Gilles Peskine 178c9aa966 Key derivation: forbid output_key without input_key
If none of the inputs to a key derivation is a
PSA_KEY_DERIVATION_INPUT_SECRET passed with
psa_key_derivation_input_key(), forbid
psa_key_derivation_output_key(). It usually doesn't make sense to
derive a key object if the secret isn't itself a proper key.

Gilles Peskine 1a2904c49a derive_input test function: Try output afterwards
After passing some inputs, try getting one byte of output, just to
check that this succeeds (for a valid sequence of inputs) or fails
with BAD_STATE (for an invalid sequence of inputs). Either output a
1-byte key or a 1-byte buffer depending on the test data.

The test data was expanded as follows:
* Output key type (or not a key): same as the SECRET input if success
  is expected, otherwise NONE.
* Expected status: PSA_SUCCESS after valid inputs, BAD_STATE after any
  invalid input.

Gilles Peskine 224b0d656a Key derivation: allow both keys and direct inputs
Allow a direct input as the SECRET input step in a key derivation, in
addition to allowing DERIVE keys. This makes it easier for
applications to run a key derivation where the "secret" input is
obtained from somewhere else. This makes it possible for the "secret"
input to be empty (keys cannot be empty), which some protocols do (for
example the IV derivation in EAP-TLS).

Conversely, allow a RAW_DATA key as the INFO/LABEL/SALT/SEED input to a key
derivation, in addition to allowing direct inputs. This doesn't
improve security, but removes a step when a personalization parameter
is stored in the key store, and allows this personalization parameter
to remain opaque.

Add test cases that explore step/key-type-and-keyhood combinations.

Gilles Peskine efa2ac879d Uniquify test case descriptions
Make check-test-cases.py pass.

Prior to this commit, there were many repeated test descriptions, but
none with the same test data and dependencies and comments, as checked
with the following command:

    for x in tests/suites/*.data; do perl -00 -ne 'warn "$ARGV: $. = $seen{$_}\n" if $seen{$_}; $seen{$_}=$.' $x; done

Wherever a test suite contains multiple test cases with the exact same
description, add " [#1]", " [#2]", etc. to make the descriptions
unique. We don't currently use this particular arrangement of
punctuation, so all occurrences of " [#" were added by this script.

I used the following ad hoc code:

import sys

def fix_test_suite(data_file_name):
    in_paragraph = False
    total = {}
    index = {}
    lines = None
    with open(data_file_name) as data_file:
        lines = list(data_file.readlines())
        for line in lines:
            if line == '\n':
                in_paragraph = False
                continue
            if line.startswith('#'):
                continue
            if not in_paragraph:
                # This is a test case description line.
                total[line] = total.get(line, 0) + 1
                index[line] = 0
            in_paragraph = True
    with open(data_file_name, 'w') as data_file:
        for line in lines:
            if line in total and total[line] > 1:
                index[line] += 1
                line = '%s [#%d]\n' % (line[:-1], index[line])

Gilles Peskine 44393c81aa psa_crypto: Add an ECDH+HKDF test with longer output
A test case for 32+0 was present three times, evidently overeager
copy-paste. Replace the duplicates by test cases that read more than
32 bytes, which exercises HKDF a little more (32 bytes is significant
because HKDF-SHA-256 produces output in blocks of 32 bytes).

I obtained the test data by running our implementation, because we're
confident in our implementation now thanks to other test cases: this
data is useful as a non-regression test.

Hanno Becker 6dfa665398 X.509: Add numerous negative parsing tests for CertificatePolicy ext
This commit adds multiple test cases to the X.509 CRT parsing test suite
exercising the stack's behaviour when facing CertificatePolicy extensions
that are malformed for a variety of reasons. It follows the same scheme
as in other negative parsing tests: For each ASN.1 component, have test
cases for (a) unexpected tag, (b) missing length, (c) invalid length
encoding, (d) length out of bounds.

Hanno Becker c15ff98455 X.509: Adapt negative parsing test for no data in CrtPolicy ext
This commit modifies the test

   X509 CRT ASN1 (TBSCertificate v3, inv CertificatePolicies, data missing)

which exercises the behaviour of the X.509 CRT parser when facing a
CertificatePolicy extension with empty data field.

The following adaptations are made:
- The subject ID and issuer ID are modified to have length 0.
  The previous values `aa` and `bb` are OK, but a generic ASN.1
  parser will try to interpret them as ASN.1 tags and fail. For
  maintainability, it's therefore better to use something that
  can be parsed as ASN.1, and an empty ID is the easiest solution
  here.
- The TBS part of the certificate wasn't followed by signature
  algorithm and signature fields, which makes the test incompatible
  with future changes swapping to breadth-first parsing of
  certificates.

Hanno Becker 82a1fe5fcc X.509: Remove CRT policy parsing test 'bool len missing'
Judging from its name, the purpose of the test

   TBSCertificate v3, ext CertificatePolicies tag, bool len missing

in test_suite_x509parse.data is to exercise the X.509 parsing stack's
behaviour when parsing a CertificatePolicy extension which lacks the
length field of the boolean 'Criticality' value.

However, the test fails at an earlier stage due to a mismatch of inner
and outer length of the explicit ASN.1 extensions structure.

Since we already have tests exercising

- mismatch of inner and outer length in the extensions structure, namely
  'X509 CRT ASN1 (TBS, inv v3Ext, inner tag invalid)'
- missing length of the 'Criticality' field in an extension, namely
  'X509 CRT ASN1 (TBS, inv v3Ext, critical length missing)'

and since for both tests there's no relevance to the use of the
policy extension OID, the test

  'TBSCertificate v3, ext CertificatePolicies tag, bool len missing'

can be dropped.

actually out of range for int.

Tweak test data for one test case to not rely on
mbedtls_asn1_get_bitstring_null rejecting bitstrings shorter than two
octets. Instead, try bit strings that are genuinely invalid, or have a
nonzero number of unused bits.

Add a test case with a correct empty signature. This is commented out
because asn1parse currently does not support this. Uncomment it when
asn1parse is updated to support this.

Gilles Peskine 2cd8ecc08b New test helper macro ASSERT_ALLOC_WEAK
The new macro ASSERT_ALLOC_WEAK does not fail the test case if the

large amount of memory, but that aren't useful on platforms where
allocating such a large amount is not possible.

Ideally this macro should mark the test as skipped. We don't yet have
a facility for that but we're working on it. Once we have a skip

Gilles Peskine 3f37dca794 asn1write: Test short and large buffers more systematically
Use the test-many-sizes framework for string writes as
well (previously, it was only used for booleans and integers). This
way, more edge cases are tested with less test code.

This commit removes buffer overwrite checks. Instead of these checks,
run the test suite under a memory sanitizer (which we do in our CI).

Gilles Peskine 3a032c36c1 Add test cases for BOOLEANs and INTEGERs
Omit negative integers and MPIs that would result in values that look
like negative INTEGERs, since the library doesn't respect the
specifications there, but fixing it has a serious risk of breaking
interoperability when ASN.1 is used in X.509 and other
cryptography-related applications.

Gilles Peskine 27d806fab4 Add ASN.1 parsing tests
Add self-contained ASN.1 parsing tests, so that ASN.1 parsing is not
solely tested through X.509 and TLS.

The tests cover every function and almost complete line coverage in
asn1parse.c.

A few test cases containing negative and edge case INTEGER values are
deliberately deactivated because the historical library behavior is at
odds with official specifications, but changing the behavior might
break interoperability.

Other than that, these tests revealed a couple of minor bugs which
will be fixed in subsequent commits.

Hanno Becker f9b3303eb9 Introduce specific error for ver/cfg mismatch on deserialization
This commit introduces a new SSL error code

  `MBEDTLS_ERR_SSL_VERSION_MISMATCH`

which can be used to indicate operation failure due to a
mismatch of version or configuration.

It is put to use in the implementation of `mbedtls_ssl_session_load()`
to signal the attempt to de-serialize a session which has been serialized
in a build of Mbed TLS using a different version or configuration.

Hanno Becker fe1275e3fe Improve test for detection of ver/cfg corruption in serialized data
This commit improves the test exercising the behaviour of

only tested the first bit of each byte.

Manuel Pégourié-Gonnard a3d831b9e6 Add test for session_load() from small buffers
This uncovered a bug that led to a double-free (in practice, in general could
be free() on any invalid value): initially the session structure is loaded
with `memcpy()` which copies the previous values of pointers peer_cert and
ticket to heap-allocated buffers (or any other value if the input is
attacker-controlled). Now if we exit before we got a chance to replace those
invalid values with valid ones (for example because the input buffer is too
small, or because the second malloc() failed), then the next call to
session_free() is going to call free() on invalid pointers.

This bug is fixed in this commit by always setting the pointers to NULL right
after they've been read from the serialised state, so that the invalid values
can never be used.

(An alternative would be to NULL-ify them when writing, which was rejected
mostly because we need to do it when reading anyway (as the consequences of
free(invalid) are too severe to take any risk), so doing it when writing as
well is redundant and a waste of code size.)

Also, while thinking about what happens in case of errors, it became apparent
to me that it was bad practice to leave the session structure in an
half-initialised state and rely on the caller to call session_free(), so this
commit also ensures we always clear the structure when loading failed.

Manuel Pégourié-Gonnard f5fa0aa664 Add test for session_save() on small buffers 2019-08-23 12:48:41 +03:00
Manuel Pégourié-Gonnard 5b1674e0ba Disable test for load-save identity
This test appeared to be passing for the wrong reason, it's actually not
appropriate for the current implementation. The serialised data contains
values of pointers to heap-allocated buffers. There is no reason these should
be identical after a load-save pair. They just happened to be identical when I
first ran the test due to the place of session_free() in the test code and the
fact that the libc's malloc() reused the same buffers. The test no longer
passes if other malloc() implementations are used (for example, when compiling
with asan which avoids re-using the buffer, probably for better error
detection).

So, disable this test for now (we can re-enable it when we changed how
sessions are serialised, which will be done in a future PR, hence the name of
the dummy macro in depends_on). In the next commit we're going to add a test
that save-load is the identity instead - which will be more work in testing as
it will require checking each field manually, but at least is reliable.

Manuel Pégourié-Gonnard 6eac11b007 Start adding unit test for session serialisation
This initial test ensures that a load-save function is the identity. It is so

Gilles Peskine f3801fff77 Update import_key and generate_key SE methods to the current API
The methods to import and generate a key in a secure element drivers
were written for an earlier version of the application-side interface.
Now that there is a psa_key_attributes_t structure that combines all
key metadata including its lifetime (location), type, size, policy and
extra type-specific data (domain parameters), pass that to drivers
instead of separate arguments for each piece of metadata. This makes
the interface less cluttered.

Update parameter names and descriptions to follow general conventions.

Document the public-key output on key generation more precisely.
Explain that it is optional in a driver, and when a driver would
implement it. Declare that it is optional in the core, too (which
means that a crypto core might not support drivers for secure elements
that do need this feature).

Update the implementation and the tests accordingly.

Gilles Peskine 5386f6ba07 Fix PSA init/deinit in mbedtls_xxx tests when using PSA
In tests of mbedtls_cipher_xxx and mbedtls_pk_xxx with
MBEDTLS_USE_PSA_CRYPTO enabled, initialize and deinitialize the PSA
subsystem in every function. Before, the tests were only passing
because the first function to be called happened to call
psa_crypto_init() but not mbedtls_psa_crypto_free(). In some
configurations (not tested on CI), psa_crypto_init() was not called so
the tests using PSA failed.

Call PSA_DONE() at the end of each test function. This ensures that no
resources are leaked in the form of PSA crypto slot contents.
Incidentally, this also fixes a build error due to
test_helper_psa_done() being unused in test_suite_pk: the fact that it
wasn't used betrayed the missing calls to PSA_DONE().

Jaeden Amero 8dd1690993 Merge remote-tracking branch 'tls/development' into development
Resolve conflicts by performing the following operations:
- Reject changes related to building a crypto submodule, since Mbed
  Crypto is the crypto submodule.
- Reject X.509, NET, and SSL changes.
- Reject changes to README, as Mbed Crypto is a different project from
  Mbed TLS, with a different README.
- Avoid adding mention of ssl-opt.sh in a comment near some modified
  code in include/CMakeLists.txt (around where ENABLE_TESTING as added).
- Align config.pl in Mbed TLS with config.pl in Mbed Crypto where PSA
  options are concerned, to make future merging easier. There is no
  reason for the two to be different in this regard, now that Mbed TLS
  always depends on Mbed Crypto. Remaining differences are only the
  PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option and the absence of X.509,
  NET, and SSL related options in Mbed Crypto's config.pl.
- Align config.h in Mbed Crypto with Mbed TLS's copy, with a few notable
  exceptions:
  - Leave CMAC on by default.
  - Leave storage on by default (including ITS emulation).
  - Avoid documenting the PSA Crypto API as is in beta stage in
    documentation for MBEDTLS_PSA_CRYPTO_C.
  The only remaining differences are a lack of X.509, NET, and SSL
  options in Mbed Crypto's config.h, as well as an additional
  Mbed-Crypto-specific PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option.
  Documentation for the check params feature and related macros is also
  updated to match Mbed TLS's description.
- Reject tests/data_files/Makefile changes to generate DER versions of
  CRTs and keys, as none of those are used by Mbed Crypto tests.
- Add the "no PEM and no filesystem" test to all.sh, without ssl-opt.sh
  run, as Mbed Crypto doesn't have ssl-opt.sh. Also remove use of PSA
  Crypto storage and ITS emulation, since those depend on filesystem
  support.
- Reject addition of test when no ciphersuites have MAC to all.sh, as
  the option being tested, MBEDTLS_SSL_SOME_MODES_USE_MAC, is not
  present in Mbed Crypto.
- Use baremetal config in all.sh, as Mbed Crypto's baremetal
  configuration does exclude the net module (as it doesn't exist in Mbed
  Crypto)
- Reject cmake_subproject_build changes, continuing to link only
  libmbedcrypto.
- Reject changes to visualc and associated templates. Mbed Crypto
  doesn't need additional logic to handle submodule-sourced headers.
- Avoid adding fuzzers from Mbed TLS. The only relevant fuzzers are the
  privkey and pubkey fuzzers, but non-trivial work would be required to
  integrate those into Mbed Crypto (more than is comfortable in a merge
  commit).
- Reject addition of Docker wrappers for compat.sh and ssl-opt.sh, as
  those are not present in Mbed Crypto.
- Remove calls to SSL-related scripts from basic-in-docker.sh

Fix test errors by performing the following:
- Avoid using a link that Doxygen can't seem to resolve in Mbed Crypto,
  but can resolve in Mbed TLS. In documentation for
  MBEDTLS_CHECK_PARAMS, don't attempt to link to MBEDTLS_PARAM_FAILED.

Gilles Peskine c744d99386 Limit keys to 65528 bits
65528 bits is more than any reasonable key until we start supporting
post-quantum cryptography.

This limit is chosen to allow bit-sizes to be stored in 16 bits, with
65535 left to indicate an invalid value. It's a whole number of bytes,
which facilitates some calculations, in particular allowing a key of
exactly PSA_CRYPTO_MAX_STORAGE_SIZE to be created but not one bit
more.

As a resource usage limit, this is arguably too large, but that's out
of scope of the current commit.

Test that key import, generation and derivation reject overly large
sizes.

Gilles Peskine 1801740a7c SE driver: report the bit size on key import
Add a parameter to the key import method of a secure element driver to
make it report the key size in bits. This is necessary (otherwise the
core has no idea what the bit-size is), and making import report it is
easier than adding a separate method (for other key creation methods,
this information is an input, not an output).

Run all functions that take a key handle as input with a key that is
in a secure element. All calls are expected to error out one way or
another (not permitted by policy, invalid key type, method not
implemented in the secure element, ...). The goal of this test is to
ensure that nothing bad happens (e.g. invalid pointer dereference).

Run with various key types and algorithms to get good coverage.

PSA Storage: Add psa_trusted_storage_linux persistent storage support for v1.0.0 APIs
2019-07-24 11:19:32 +01:00
Simon D Hughes bda5a21112 Add psa_trusted_storage_linux persistent storage support for v1.0.0 APIs
The following provides more information on this PR:
- PSA stands for Platform Security Architecture.
- Add support for use of psa_trusted_storage_api internal_trusted_storage.h v1.0.0
  as the interface to the psa_trusted_storage_linux backend (i.e. for persistent
  storage when MBEDTLS_PSA_ITS_FILE_C is not defined). This requires changes
  to psa_crypto_its.h and psa_crypto_storage.c to migrate to the new API.

2019-07-23 16:13:14 +02:00
Gilles Peskine 0e8d495bd9 Add the lifetime to the key storage format
Stored keys must contain lifetime information. The lifetime used to be
implied by the location of the key, back when applications supplied
the lifetime value when opening the key. Now that all keys' metadata
are stored in a central location, this location needs to store the
lifetime explicitly.
2019-07-23 14:46:52 +02:00
Gilles Peskine bfd322ff34 Use a key attribute structure in the internal storage interface
Pass information via a key attribute structure rather than as separate
parameters to psa_crypto_storage functions. This makes it easier to
maintain the code when the metadata of a key evolves.

This has negligible impact on code size (+4B with "gcc -Os" on x86_64).

Gilles Peskine 66afcca5a9 entropy_nv_seed: cope with SHA-256
This test case was only executed if the SHA-512 module was enabled and
MBEDTLS_ENTROPY_FORCE_SHA256 was not enabled, so "config.pl full"
didn't have a chance to reach it even if that enabled
MBEDTLS_PLATFORM_NV_SEED_ALT.

Now all it takes to enable this test is MBEDTLS_PLATFORM_NV_SEED_ALT
and its requirements, and the near-ubiquitous MD module.

Gilles Peskine e39b903de5 entropy_nv_seed: clean up properly
Call mbedtls_entropy_free on test failure.

Restore the previous NV seed functions which the call to

but only because the NV seed functions used for these tests happened
to work for the tests that got executed later in the .data file.

Janos Follath adbec81cc4 Remove the deprecated PSA_ALG_SELECT_RAW option
This change affects the psa_key_derivation_s structure. With the buffer
removed from the union, it is empty if MBEDTLS_MD_C is not defined.

We can avoid undefined behaviour by adding a new dummy field that is
always present or make the whole union conditional on MBEDTLS_MD_C.

In this latter case the initialiser macro has to depend on MBEDTLS_MD_C
as well. Furthermore the first structure would be either
psa_hkdf_key_derivation_t or psa_tls12_prf_key_derivation_t both of
which are very deep and would make the initialisation macro difficult
to maintain, therefore we go with the first option.

Add the compile time option PSA_PRE_1_0_KEY_DERIVATION. If this is not

Most of the tests regarding key derivation haven't been adapted to the
new API yet and some of them have only been adapted partially. When this
new option is turned off, the tests using the old API and test cases
using the old API of partially adapted tests are skipped.

The sole purpose of this option is to make the transition to the new API
smoother. Once the transition is complete it can and should be removed
along with the old API and its implementation.

2. Convert the characters to binary bytes.

This is done because the mbed tools translate the encoding differently
(mbed-greentea, and mbed-htrunner)

yet, but this will be the case in a subsequent commit.

Move PSA_ASSERT to psa_helpers.function, since that's the sort of
things it's for.

Include "psa_helpers.function" from the PSA crypto tests.

In the ITS test, don't include "psa_helpers". The ITS tests are
meant to stand alone from the rest of the library.

harder because the binary data isn't valid DER-encoded ASN.1.

This commit uses the ASN.1 NULL TLV '05 00' to test invalid
tags, and adapts surrounding structures' length values accordingly.
This eases reviewing because now the ASN.1 structures are still
well-formed at the place where the mismatch occurs.

Hanno Becker 6ccfb18ab1 Always return a high-level error code from X.509 module
Some functions within the X.509 module return an ASN.1 low level
error code where instead this error code should be wrapped by a
high-level X.509 error code as in the bulk of the module.

Specifically, the following functions are affected:
- mbedtls_x509_get_ext()
- x509_get_version()
- x509_get_uid()

This commit modifies these functions to always return an
X.509 high level error code.

Care has to be taken when adapting `mbetls_x509_get_ext()`:
Currently, the callers `mbedtls_x509_crt_ext()` treat the
return code `MBEDTLS_ERR_ASN1_UNEXPECTED_TAG` specially to
gracefully detect and continue if the extension structure is not
present. Wrapping the ASN.1 error with
`MBEDTLS_ERR_X509_INVALID_EXTENSIONS` and adapting the check
accordingly would mean that an unexpected tag somewhere
down the extension parsing would be ignored by the caller.

The way out of this is the following: Luckily, the extension
structure is always the last field in the surrounding structure,
so if there is some data remaining, it must be an Extension
structure, so we don't need to deal with a tag mismatch gracefully
in the first place.

We may therefore wrap the return code from the initial call to
`mbedtls_asn1_get_tag()` in `mbedtls_x509_get_ext()` by
`MBEDTLS_ERR_X509_INVALID_EXTENSIONS` and simply remove
the special treatment of `MBEDTLS_ERR_ASN1_UNEXPECTED_TAG`
in the callers `x509_crl_get_ext()` and `x509_crt_get_ext()`.

This renders `mbedtls_x509_get_ext()` unsuitable if it ever
happened that an Extension structure is optional and does not
occur at the end of its surrounding structure, but for CRTs
and CRLs, it's fine.

The following tests need to be adapted:
- "TBSCertificate v3, issuerID wrong tag"
  The issuerID is optional, so if we look for its presence
  but find a different tag, we silently continue and try
  parsing the subjectID, and then the extensions. The tag '00'
  used in this test doesn't match either of these, and the
  previous code would hence return LENGTH_MISMATCH after
  unsucessfully trying issuerID, subjectID and Extensions.
  With the new code, any data remaining after issuerID and
  subjectID _must_ be Extension data, so we fail with
  UNEXPECTED_TAG when trying to parse the Extension data.
- "TBSCertificate v3, UIDs, invalid length"
  The test hardcodes the expectation of
  MBEDTLS_ERR_ASN1_INVALID_LENGTH, which needs to be
  wrapped in MBEDTLS_ERR_X509_INVALID_FORMAT now.

Fixes #2431.
2019-06-04 13:59:48 +01:00
Hanno Becker 12f62fb82c Obey bounds of ASN.1 substructures
When parsing a substructure of an ASN.1 structure, no field within
the substructure must exceed the bounds of the substructure.
Concretely, the `end` pointer passed to the ASN.1 parsing routines
must be updated to point to the end of the substructure while parsing
the latter.

This was previously not the case for the routines
- x509_get_attr_type_and_value(),
- mbedtls_x509_get_crt_ext(),
- mbedtls_x509_get_crl_ext().
These functions kept using the end of the parent structure as the
`end` pointer and would hence allow substructure fields to cross
the substructure boundary. This could lead to successful parsing
of ill-formed X.509 CRTs.

This commit fixes this.

Care has to be taken when adapting `mbedtls_x509_get_crt_ext()`
and `mbedtls_x509_get_crl_ext()`, as the underlying function
`mbedtls_x509_get_ext()` returns `0` if no extensions are present
but doesn't set the variable which holds the bounds of the Extensions
structure in case the latter is present. This commit addresses
this by returning early from `mbedtls_x509_get_crt_ext()` and
`mbedtls_x509_get_crl_ext()` if parsing has reached the end of
the input buffer.

The following X.509 parsing tests need to be adapted:
- "TBSCertificate, issuer two inner set datas"
  This test exercises the X.509 CRT parser with a Subject name
  which has two empty `AttributeTypeAndValue` structures.
  This is supposed to fail with `MBEDTLS_ERR_ASN1_OUT_OF_DATA`
  because the parser should attempt to parse the first structure
  and fail because of a lack of data. Previously, it failed to
  obey the (0-length) bounds of the first AttributeTypeAndValue
  structure and would try to interpret the beginning of the second
  AttributeTypeAndValue structure as the first field of the first
  AttributeTypeAndValue structure, returning an UNEXPECTED_TAG error.
- "TBSCertificate, issuer, no full following string"
  This test exercises the parser's behaviour on an AttributeTypeAndValue
  structure which contains more data than expected; it should therefore
  fail with MBEDTLS_ERR_ASN1_LENGTH_MISMATCH. Because of the missing bounds
  check, it previously failed with UNEXPECTED_TAG because it interpreted
  the remaining byte in the first AttributeTypeAndValue structure as the
  first byte in the second AttributeTypeAndValue structure.
- "SubjectAltName repeated"
  This test should exercise two SubjectAltNames extensions in succession,
  but a wrong length values makes the second SubjectAltNames extension appear
  outside of the Extensions structure. With the new bounds in place, this
  therefore fails with a LENGTH_MISMATCH error. This commit adapts the test
  data to put the 2nd SubjectAltNames extension inside the Extensions
  structure, too.

Hanno Becker 6c87b3f9df Record enc/dec tests: Don't take turns in sending / receiving roles
Part of the record encryption/decryption tests is to gradually
increase the space available at the front and/or at the back of
a record and observe when encryption starts to succeed. If exactly
one of the two parameters is varied at a time, the expectation is
that encryption will continue to succeed once it has started
succeeding (that's not true if both pre- and post-space are varied
at the same time).

Moreover, previously the test would take turns when choosing which
transform should be used for encryption, and which for decryption.

With the introduction of the CID feaature, this switching of transforms
doesn't align with the expectation of eventual success of the encryption,
since the overhead of encryption might be different for the parties,
because both parties may use different CIDs for their outgoing records.

This commit modifies the tests to not take turns between transforms,
but to always use the same transforms for encryption and decryption
during a single round of the test.

Manually cherry-picked from ca5bed742f
by taking that patch, replacing KEYPAIR by KEY_PAIR
throughout (renaming applied in this branch), and discarding parts
about import_twice in test_suite_psa_crypto (this test function was
removed from this branch).

Gilles Peskine 705cbfd802 Enrollment algorithm in policy: add support in psa_copy_key tests
Add parameters to psa_copy_key tests for the enrollment algorithm (alg2).

This commit only tests with alg2=0, which is equivalent to not setting
an enrollment algorithm.

Gilles Peskine cbce4d8889 Persistent key reload: test more metadata
In the tests for opening a persistent key after closing it, also read
back and check the key data if permitted by policy, and the key
policy.

Gilles Peskine 2c86ebc2f8 EC key pair import: check the buffer size
When importing a private elliptic curve key, require the input to have
exactly the right size. RFC 5915 requires the right size (you aren't
allowed to omit leading zeros). A different buffer size likely means
that something is wrong, e.g. a mismatch between the declared key type
and the actual data.

Jaeden Amero 3d07ffade2 Merge remote-tracking branch 'tls/development' into development
Resolve conflicts by performing the following operations:
    - Reject changes to files removed during the creation of Mbed Crypto
      from Mbed TLS.
    - Reject the addition of certificates that would not be used by any
      tests, including rejecting the addition of Makefile rules to
      generate these certificates.
    - Reject changes to error.c referencing modules that are not part of
      Mbed Crypto.

Gilles Peskine 35ef36b62f Rename psa_generate_random_key back to psa_generate_key
generate_key is a more classical name. The longer name was only
introduced to avoid confusion with getting a key from a generator,
which is key derivation, but we no longer use the generator
terminology so this reason no longer applies.
