Fix misuse of signed ints in the HAVEGE module
2019-07-05 15:30:30 +01:00
k-stachowiak 653a4a2fba Prevent dead code warning
The window size variable in ecp_pick_window_size() can take values
4, 5 or 6, but we clamp it not to exceed the value of
MBEDTLS_ECP_WINDOW_SIZE. If that is 6 (default) or higher, the
static analyzer will point out that the test:
w > MBEDTLS_ECP_WINDOW_SIZE always evaluates to false.

This commit removes the test for the cases of the window size
large enough to fit all the potential values of the variable.

Ashley Duncan d85a7e9b09 Remove use of CMAKE_SOURCE_DIR
Remove use of CMAKE_SOURCE_DIR in case mbedtls is built from within
another CMake project. Define MBEDTLS_DIR to ${CMAKE_CURRENT_SOURCE_DIR}
in the main CMakeLists.txt file and refer to that when defining target
include paths to enable mbedtls to be built as a sub project.

Fixes https://github.com/ARMmbed/mbedtls/issues/2609

Gilles Peskine 7846299adb Fix misuse of signed ints in the HAVEGE module
The elements of the HAVEGE state are manipulated with bitwise
operations, with the expectations that the elements are 32-bit
unsigned integers (or larger). But they are declared as int, and so
the code has undefined behavior. Clang with Asan correctly points out
some shifts that reach the sign bit.

Since these are supposed to be 32-bit unsigned integers, declare them
as uint32_t.

This is technically an API break, since the type mbedtls_havege_state
is exposed in a public header. However normal applications should not
be affected.

Jaeden Amero 7654161dbf psa: Add NV seed as an entropy source when needed
When MBEDTLS_PSA_INJECT_ENTROPY is used, we now require also defining
MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES. When
MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES is defined, we do not add entropy
sources by default. This includes the NV seed entropy source, which the
PSA entropy injection API is built upon.

The PSA entropy injection feature depends on using NV seed as an entropy
source. Add NV seed as an entropy source for PSA entropy injection.

Fixes e3dbdd8d90 ("Gate entropy injection through a dedicated configuration option")

Hanno Becker 8b0f9e6388 Allow DHM selftest to run if MBEDTLS_PEM_PARSE_C is unset
If MBEDTLS_PEM_PARSE_C is unset, the DHM selftest fails because
it uses PEM encoded test data.

This commit fixes this by providing the DER encoded form of the
test data instead in case MBEDTLS_PEM_PARSE_C is unset.

Jaeden Amero 8d4d4f55f0 Makefile: Use full paths to refer to parent files
When running lcov, files can't be found relative to the parent project
(Mbed TLS) root. Use full, non-relative paths to refer to files used in
building Mbed Crypto from Mbed TLS in order to enable lcov to locate the
files properly.

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.

set the returned error code to `MBEDTLS_ERR_X509_FEATURE_UNAVAILABLE`
and continue parsing. If the extension is critical, return error anyway,
unless `MBEDTLS_X509_ALLOW_UNSUPPORTED_CRITICAL_EXTENSION` is configured.
Fail parsing on any other error.

Janos Follath 293c3dae6d Remove redundant memset()
The preceding calloc() already zeroizes that memory area, therfore the
memset() is not necessary. Compilers are likely to optimize this out,
but it still can be confusing to readers.

Janos Follath 6c379b4b80 Propogate error when parsing SubjectAltNames
The previous behaviour of mbedtls_x509_parse_subject_alternative_name()
was to silently ignore errors coming from x509_get_other_name(). The
current commit fixes it and returns with an error.

Janos Follath 2f0ec1e3bf Tidy up style in x509_info_subject_alt_name 2019-05-10 11:06:31 +01:00
Janos Follath 22f605fbab Print unparseable SubjectAlternativeNames
In x509_info_subject_alt_name() we silently dropped names that we
couldn't parse because they are not supported or are malformed. (Being
malformed might mean damaged file, but can be a sign of incompatibility
between applications.)

This commit adds code notifying the user that there is something, but
we can't parse it.
2019-05-10 10:57:44 +01:00
Janos Follath ab23cd1eae Remove unneeded checks from x509_get_other_name
Lengths are aleady checked in mbedtls_asn1_get_len() which is called in
mbedtls_asn1_get_tag(), therefore it is not necessary to check
the lengths explicitly afterwards.

Also with the previous flow data was left in the output buffer on some
errors.

Resolve merge conflicts by performing the following actions:

- Reject changes to deleted files.
- Reject changes to generate_errors.pl and generate_visualc_files.pl.
  Don't add an 'include-crypto' option which would attempt to use the
  non-existent crypto submodule.
- list-identifiers.sh had the `--internal` option added to it, which
  lists identifiers only in internal headers. Add PSA-specific internal
  headers to list-identifiers.sh.

Autogenerate errors.c There are changes in error.c due to updating the
crypto submodule to a version that no longer has the SSL, X.509, or net
modules. The errors are correctly sourced from Mbed TLS and not Mbed
Crypto, but they do move around within the file due to how the error
