Gilles Peskine 344e15b010 Update SE support to pass a location when registering a driver
Now that lifetimes have structures and secure element drivers handle
all the lifetimes with a certain location, update driver registration
to take a location as argument rather than a lifetime.

This commit updates the tests.

Andrzej Kurek 1605074f97
Guard from undefined behaviour in case of an INT_MAX max_pathlen
When parsing a certificate with the basic constraints extension
the max_pathlen that was read from it was incremented regardless
of its value. However, if the max_pathlen is equal to INT_MAX (which
is highly unlikely), an undefined behaviour would occur.
This commit adds a check to ensure that such value is not accepted
as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced.
Certificates added in this commit were generated using the
test_suite_x509write, function test_x509_crt_check. Input data taken 
from the "Certificate write check Server1 SHA1" test case, so the generated
files are like the "server1.crt", but with the "is_ca" field set to 1 and
max_pathlen as described by the file name.

Gilles Peskine 6710e15921 Enable X509_ALLOW_EXTENSIONS_NON_V3 in config full and fix tests
Enable MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 in the full config. There's
no reason to keep it out. We weren't testing it at all on the CI.

Add a missing dependency on !MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 to
some test cases that either were testing that v3 extensions are only
accepted in v3 certificates, or where parsing returns a different
error when MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 is enabled.

Add a few positive and negative test cases with
MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 enabled.

Fix one test case with MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 where the
intended output of mbedtls_x509_crt_info had changed in
890819a597 but the test case was missed
because it was never executed.

Improve pointer calculations when resizing I/O buffers
This commit introduces two changes:
- Add in_msg and out_msg calculations for buffer upsizing. This was previously
considered as unnecessary, but renegotiation using certain ciphersuites needs
this.
- Improving the way out_msg and in_msg pointers are calculated, so that even 
if no resizing is introduced, the pointers remain the same;

New tests added:
- various renegotiation schemes with a range of MFL's and ciphersuites;
- an ssl-opt.sh test exercising two things that were problematic: renegotiation
with TLS-ECDHE-ECDSA-WITH-AES-128-CCM-8 and a server MFL that's smaller
than the one negotiated by the client.

Gilles Peskine 06725c985f Fix intermittent crash in test suites with outcome file enabled
Fix an intermittent crash when running test suites in non-verbose
mode (i.e. with -v off) and with the outcome file enabled. The
array unmet_dependencies was only filled in verbose mode, but was used
in write_outcome_result regardless.

Since unmet_dependencies only ever contains strings that are integers
written out in decimal, store the integer instead. Do this
unconditionally since it doesn't cost any extra memory.

It would be better to record the dependency names, both in the verbose
output and in the outcome file. But the dependency names are not
currently available at runtime.

Gilles Peskine b99bd39b4e Merge mbed-crypto into mbedtls: the merge commit
Merge `unremove-non-crypto` into `mbedtls/development`. The branch
`unremove-non-crypto` was obtained by starting from `mbed-crypto/development`,
then reverting many commits that removed X.509 and TLS functionality when Mbed
Crypto forked from Mbed TLS (the “unremoval”), then make a few tweaks to
facilitate the merge.

The unremoval step restored old versions of some tls files. If a file doesn't
exist in mbed-crypto, check out the mbedtls version, regardless of what
happened during the unremoval of tls files in the crypto tree. Also
unconditionally take the mbedtls version of a few files where the
modifications are completely project-specific and are not relevant in
mbed-crypto:

* `.github/issue_template.md`: completely different. We may want to reconcile
  them independently as a follow-up.
* `.travis.yml`: would only be reverted to an earlier tls version.
* `README.md`: completely different. We may want to reconcile them
  independently as a follow-up.
* `doxygen/input/doc_mainpage.h`: the changes in crypto were minimal and not
  relevant except as a stopgap as mbed-crypto did not have its own product
  versioning in the Doxygen documentation.
* `tests/.jenkins/Jenkinsfile`: completely different.
* `tests/data_files/Makefile`: there were no changes in mbed-crypto,
  but the unremoval step restored an old version.

Shell script for everything to do after the merge apart from the conflict
resolution:
```
tls_files=($(comm -23 <(git ls-tree -r --name-only HEAD) <(git ls-tree -r --name-only $(git merge-base upstream-crypto/development MERGE_HEAD))))
tls_files+=($tls_files .github/issue_template.md .travis.yml README.md doxygen/input/doc_mainpage.h tests/.jenkins/Jenkinsfile tests/data_files/Makefile)
git checkout --theirs HEAD -- $tls_files
git add -- $tls_files
```

Resolve the remaining conflicts:

* `library/CMakeLists.txt`:
    * Keep the TLS definition of `src_crypto`
    * `USE_SHARED_MBEDTLS_LIBRARY`: keep all three libraries, with both
      `include` and `crypto/include` in `target_include_directories`, all with
      version `2.21.0`.
* `programs/Makefile`:
    * Reconcile the APPS lists (add/add from a differently-formatted common
      ancestor): insert the `psa/*` from crypto into the tls list.
    * Keep the `fuzz` target defined only in tls version.
    * Keep the recipe (only in tls version) cleaning `ssl_pthread_server`
      stuff for the `clean` target.
* `scripts/config.py`:
    * `include_in_full`: add/add conflict. Keep both.
* `tests/scripts/all.sh`:
    * `component_test_no_use_psa_crypto_full_cmake_asan`: partially old
      version in crypto. Take the tls version.
    * `component_test_malloc_0_null` and more: take
      `component_test_malloc_0_null` from crypto (with `config.py` rather than
      `config.pl`, and with `$ASAN_FLAGS` rather than an explicit list), but
      add the call to `ssl-opt.sh` from tls. Take the other components from
      crypto.

With this commit, building and running the unit tests with both `make ` and
`cmake` work in the default configuration on Linux. Other platforms, build
systems and configurations are likely not to work, and there is some
regression in test coverage.

There is some loss of functionality because the unremoval step restored older
versions of tls content. This commit contains the latest tls version of
tls-only files, but some changes from the tls side in files that existed on
both sides have regressed. Most problematic changes are hunks that remove some
tls-specific feature and contain either a C preprocessor symbol identifying a
tls-specific module or option, or the name of a tls-specific file. Hunks
that remove a tls-specific preprocessor symbol can be identified with the
regular expression `^-.*MBEDTLS_(ERR_)?(PKCS11|X509|NET|SSL)_`.

Subsequent commits will revert a few parts of the patch from this merge commit
in order to restore the tls functionality that it removes, ensure that the
test coverage includes what was covered in either branch, and fix test
failures.

Gilles Peskine 7cfcb3fc03 Change the encoding of key types to have a parity bit
Change the encoding of key types, EC curve families and DH group
families to make the low-order bit a parity bit (with even parity).

This ensures that distinct key type values always have a Hamming
distance of at least 2, which makes it easier for implementations to
resist single bit flips.

Gilles Peskine f65ed6f254 Change key types to a 16-bit encoding
All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.

Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.

Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.

Reorder psa_core_key_attributes_t to avoid padding.

Gilles Peskine b87b719467 Remove old values of curve encodings

Gilles Peskine 228abc5773 Define EC curve family constants
Define constants for ECC curve families and DH group families. These
constants have 0x0000 in the lower 16 bits of the key type.

Support these constants in the implementation and in the PSA metadata
tests.

Switch the slot management and secure element driver HAL tests to the
new curve encodings. This requires SE driver code to become slightly
more clever when figuring out the bit-size of an imported EC key since
it now needs to take the data size into account.

Switch some documentation to the new encodings.

Remove the macro PSA_ECC_CURVE_BITS which can no longer be implemented.
2020-01-31 10:15:32 +01:00
Gilles Peskine 025fccdc32 Change the encoding of EC curves and DH groups to include the size
Change the representation of psa_ecc_curve_t and psa_dh_group_t from
the IETF 16-bit encoding to a custom 24-bit encoding where the upper 8
bits represent a curve family and the lower 16 bits are the key size
in bits. Families are based on naming and mathematical similarity,
with sufficiently precise families that no two curves in a family have
the same bit size (for example SECP-R1 and SECP-R2 are two different
families).

As a consequence, the lower 16 bits of a key type value are always
either the key size or 0.

Gilles Peskine 4295e8b9c5 Rework PSA curve to mbedlts group id conversion
Don't rely on the bit size encoded in the PSA curve identifier, in

For some inputs, the error code on EC key creation changes from
PSA_ERROR_INVALID_ARGUMENT to PSA_ERROR_NOT_SUPPORTED or vice versa.
There will be further such changes in subsequent commits.
2020-01-31 10:15:32 +01:00
Gilles Peskine 7bfcfac164 Change key type encodings to avoid bit 16
Key types are now encoded through a category in the upper 4 bits (bits
28-31) and a type-within-category in the next 11 bits (bits 17-27),
with bit 16 unused and bits 0-15 only used for the EC curve or DH
group.

For symmetric keys, bits 20-22 encode the block size (0x0=stream,
0x3=8B, 0x4=16B).

Piotr Nowicki 890b5ca330 Change non-blocking read/write in TCP mock socket
Previously mocked non-blocking read/write was returning 0 when buffer was empty/full. That was causing ERR_SSL_CONN_EOF error in tests which was using these mocked callbacks. Beside that non-blocking read/write was returning ERR_SSL_WANT_READ/_WRITE depending on block pattern set by test design. Such behavior forced to redesign of these functions so that they could be used in other tests

Gilles Peskine 95c893d17f More systematic handling of trailing garbage in parse_prefixes
Before, the string to parse may contain trailing garbage (there was

indicating the length of the content. Now, the string to parse is the
exact content, and the test code runs an extra test step with a
trailing byte added.

Gilles Peskine 42a1acfd0e get_len_step: Fix end-of-buffer calculation when buffer_size==0
Fix get_len_step when buffer_size==0. The intent of this test is to
ensure (via static or runtime buffer overflow analysis) that
mbedtls_asn1_get_len does not attempt to access beyond the end of the
buffer. When buffer_size is 0 (reached from get_len when parsing a
1-byte buffer), the buffer is buf[1..1] because allocating a 0-byte
buffer might yield a null pointer rather than a valid pointer. In this
case the end of the buffer is p==buf+1, not buf+buffer_size which is
buf+0.

The test passed because calling mbedtls_asn1_get_len(&p,end,...) with
end < p happens to work, but this is not guaranteed.

Rejected changes in non-conflicting files:

* `CMakeLists.txt`: discard their addition which has already been side-ported.
* `doxygen/mbedtls.doxyfile`: keep the version number change. Discard the changes related to `../crypto` paths.

Keep the following changes after examination:

* `.travis.yml`: all of their changes are relevant.
* `include/mbedtls/error.h`: do keep their changes. Even though Crypto doesn't use TLS errors, it must not encroach on TLS's allocated numbers.
* `tests/scripts/check-test-cases.py`: keep the code dealing with `ssl-opt.sh`. It works correctly when the file is not present.

Gilles Peskine eba088a8ac test_suite_pk: check the signature size after pk_sign
Add a check that the signature size from pk_sign is less than the
documented maximum size.

Reduce the stack consumption in pk_sign_verify.

Gilles Peskine f85e4e67bd test_suite_pk: fix use of sig_len without initialization
In pk_sign_verify, if mbedtls_pk_sign() failed, sig_len was passed to
mbedtls_pk_verify_restartable() without having been initialized. This
worked only because in the only test case that expects signature to
fail, the verify implementation doesn't look at sig_len before failing
for the expected reason.

The value of sig_len if sign() fails is undefined, so set sig_len to
something sensible.
