Andy Gross 3fc6f9d16d Fix uninitialized variable in x509_crt
This patch fixes an issue we encountered with more stringent compiler
warnings.  The signature_is_good variable has a possibility of being
used uninitialized.  This patch moves the use of the variable to a
place where it cannot be used while uninitialized.

Hanno Becker fb1b7e1db9 HMAC DRBG: Split entropy-gathering requests to reduce request sizes
According to SP800-90A, the DRBG seeding process should use a nonce
of length `security_strength / 2` bits as part of the DRBG seed. It
further notes that this nonce may be drawn from the same source of
entropy that is used for the first `security_strength` bits of the
DRBG seed. The present HMAC DRBG implementation does that, requesting
`security_strength * 3 / 2` bits of entropy from the configured entropy
source in total to form the initial part of the DRBG seed.

However, some entropy sources may have thresholds in terms of how much
entropy they can provide in a single call to their entropy gathering
function which may be exceeded by the present HMAC DRBG implementation
even if the threshold is not smaller than `security_strength` bits.
Specifically, this is the case for our own entropy module implementation
which only allows requesting at most 32 Bytes of entropy at a time
in configurations disabling SHA-512, and this leads to runtime failure
of HMAC DRBG when used with Mbed Crypto' own entropy callbacks in such
configurations.

This commit fixes this by splitting the seed entropy acquisition into
two calls, one requesting `security_strength` bits first, and another
one requesting `security_strength / 2` bits for the nonce.

Fixes #237.

Gilles Peskine e30c09198c Exclude DTLS 1.2 only with older OpenSSL
compat.sh used to skip OpenSSL altogether for DTLS 1.2, because older
versions of OpenSSL didn't support it. But these days it is supported.

We don't want to use DTLS 1.2 with OpenSSL unconditionally, because we
still use legacy versions of OpenSSL to test with legacy ciphers. So
check whether the version we're using supports it.

Gilles Peskine 560f332dd2 Document the rationale for the armel build
Call the component xxx_arm5vte, because that's what it does. Explain
"armel", and more generally why this component exists, in a comment.
2019-08-09 16:06:27 +02:00
Gilles Peskine e07b9ff2d9 Switch armel build to -Os
Without any -O option, the default is -O0, and then the assembly code
is not used, so this would not be a non-regression test for the
assembly code that doesn't build.

Aurelien Jarno a6901796f6 bn_mul.h: require at least ARMv6 to enable the ARM DSP code
Commit 16b1bd8932 "bn_mul.h: add ARM DSP optimized MULADDC code"
added some ARM DSP instructions that was assumed to always be available
when __ARM_FEATURE_DSP is defined to 1. Unfortunately it appears that
the ARMv5TE architecture (GCC flag -march=armv5te) supports the DSP
instructions, but only in Thumb mode and not in ARM mode, despite
defining __ARM_FEATURE_DSP in both cases.

This patch fixes the build issue by requiring at least ARMv6 in addition
to the DSP feature.

Darryl Green 64b4b6e35e Change worktree_rev to HEAD for rev-parse
Due to how the checking script is run in docker, worktree_rev is
ambiguous when running rev-parse. We're running it in the checked
out worktree, so we can use HEAD instead, which is unambiguous.

Gilles Peskine 5bdae19778 Add ChangeLog entry for entropy_nv_seed test case fix 2019-07-19 17:43:03 +02:00
Gilles Peskine 756b3f2c25 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.

Call mbedtls_entropy_free on test failure.

Restore the previous NV seed functions which the call to
mbedtls_platform_set_nv_seed() changed. This didn't break anything,
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.

Gilles Peskine fc41bd7f35 Don't call memset after calloc
memset has undefined behavior when either pointer can be NULL, which
is the case when it's the result of malloc/calloc with a size of 0.
The memset calls here are useless anyway since they come immediately
after calloc.

Hanno Becker 2c5ef1143d ECP restart: Don't calculate address of sub ctx if ctx is NULL
All modules using restartable ECC operations support passing `NULL`
as the restart context as a means to not use the feature.

The restart contexts for ECDSA and ECP are nested, and when calling
restartable ECP operations from restartable ECDSA operations, the
address of the ECP restart context to use is calculated by adding
the to the address of the ECDSA restart context the offset the of
the ECP restart context.

If the ECP restart context happens to not reside at offset `0`, this
leads to a non-`NULL` pointer being passed to restartable ECP
operations from restartable ECDSA-operations; those ECP operations
will hence assume that the pointer points to a valid ECP restart
address and likely run into a segmentation fault when trying to
dereference the non-NULL but close-to-NULL address.

The problem doesn't arise currently because luckily the ECP restart
context has offset 0 within the ECDSA restart context, but we should
not rely on it.

This commit fixes the passage from restartable ECDSA to restartable ECP
operations by propagating NULL as the restart context pointer.

Apart from being fragile, the previous version could also lead to
NULL pointer dereference failures in ASanDbg builds which dereferenced
the ECDSA restart context even though it's not needed to calculate the
address of the offset'ed ECP restart context.

Ron Eldor b43fe57d34 Update the test encoding to support python3
Since Python3 handles encoding differently than Python2,
a change in the way the data is encoded and sent to the target is needed.
1. Change the test data to be sent as hex string
2. Convert the characters to binary bytes.

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