David Horstmann 0763ccf04f Refactor ARIA_SELF_TEST_IF_FAIL macro 
Change the ARIA_SELF_TEST_IF_FAIL macro to be more code-style friendly.
Currently it expands to the body of an if statement, which causes
problems for automatic brace-addition for if statements.

Convert the macro to a function-like macro that takes the condition as
an argument and expands to a full if statement inside a do {} while (0)
idiom.

Manuel Pégourié-Gonnard 0771d41584 Fix missing length check 
There was a check against the remaining size of the buffer, which used
to be correct, but was broken two commits ago when we started not just
copying the input but also adding to it.

Replace it with a check that the input length is not greater that what's
expected for this step. This guarantees we won't overflow the internal
buffer.

While at it, add an explicit cast to uint8_t when writing the length to
the buffer, so silence an MSVC warning. This cast is safe because we
checked that the length is no larger than 65 or 32 (depending on the
step), so in any case is fits in one byte.

This was found because some lengths had not been adjusted in the test
suite, and instead of failing cleanly, library code performed buffer
overflows. I'll fix the tests in the next commit.

Manuel Pégourié-Gonnard ec7012dbc7 Fix I/O format of PSA EC J-PAKE for compliance 
The format used by the mbedtls_ecjpake_xxx() APIs and that defined by
the PSA Crypto PAKE extension are quite different; the former is
tailored to the needs of TLS while the later is quite generic and plain.
Previously we only addressed some part of this impedance mismatch: the
different number of I/O rounds, but failed to address the part where the
legacy API adds some extras (length bytes, ECParameters) that shouldn't
be present in the PSA Crypto version. See comments in the code.

Add some length testing as well; would have caught the issue.

David Horstmann ed79483aca Free structs in mbedtls_x509_get_name() on error 
mbedtls_x509_get_name() allocates a linked list of mbedtls_x509_name
structs but does not free these when there is an error, leaving the
caller to free them itself. Change this to cleanup these objects within
the function in case of an error.

Przemek Stekiel a82290b727 Fix guards for mbedtls_ssl_ticket_write() and mbedtls_ssl_ticket_parse() functions 
Both functions are calling mbedtls_cipher_auth_[encrypt/decrypt]_ext() functions. These functions are guarded with MBEDTLS_CIPHER_MODE_AEAD || MBEDTLS_NIST_KW_C flags - make it consistent.
As a result ssl_server2 won't build now with MBEDTLS_SSL_SESSION_TICKETS enabled (mbedtls_cipher_auth_[encrypt/decrypt]_ext() functions not available).
Mark MBEDTLS_SSL_SESSION_TICKETS as dependent on MBEDTLS_CIPHER_MODE_AEAD || MBEDTLS_NIST_KW_C and disable MBEDTLS_SSL_SESSION_TICKETS in stream cipher only build.

Ronald Cron 067a1e735e tls13: Try reasonable sig alg for CertificateVerify signature 
Instead of fully validating beforehand
signature algorithms with regards to the
private key, do minimum validation and then
just try to compute the signature. If it
fails try another reasonable algorithm if any.

Ronald Cron 38391bf9b6 tls13: Do not impose minimum hash size for RSA PSS signatures 
When providing proof of possession of
an RSA private key, allow the usage for RSA
PSS signatures of a hash with a security
level lower that the security level of the
RSA private key.

We did not allow this in the first place to
align with the ECDSA case. But as it is not
mandated by the TLS 1.3 specification (in
contrary to ECDSA), let's allow it.

Ronald Cron 67ea2543ed tls13: server: Add sig alg checks when selecting best certificate 
When selecting the server certificate based on
the signature algorithms supported by the client,
check the signature algorithms as close as possible
to the way they are checked to compute the
signature for the server to prove it possesses
the private key associated to the certificate.

That way we minimize the odds of selecting a
certificate for which the server will not be
able to compute the signature to prove it
possesses the private key associated to the
certificate.

Gilles Peskine e9b55929dc Remove useless platform macro redefinitions: automatic part 
Some source files had code to set mbedtls_xxx aliases when
MBEDTLS_PLATFORM_C is not defined. These aliases are defined unconditionally
by mbedtls/platform.h, so these macro definitions were redundant. Remove
them.

This commit used the following code:
```
perl -i -0777 -pe 's~#if !defined\(MBEDTLS_PLATFORM_C\)\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*#endif.*\n~~mg' $(git grep -l -F '#if !defined(MBEDTLS_PLATFORM_C)')

Some source files included platform.h in a nested conditional. The previous
commit "Include platform.h unconditionally: automatic part" only removed

This commit once again replaces most occurrences of conditional inclusion of

```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

Gilles Peskine 945b23c46f Include platform.h unconditionally: automatic part 
We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.

There should be no change in behavior since just including the header should
not change the behavior of a program.

This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:

```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

Tom Cosgrove f334d9622b Add unit tests for bignum_new.c:mbedtls_mpi_core_montmul() 
These tests are also used to test the existing mpi_montmul() function (which
too is renamed with mbedtls_ prefix). Some of these are replays of captured
invocations during unit test runs. Others are generated.  They use a mixture
of primes and odd numbers for N, with four randomly-generated cases for each N.

The lines in the .data file were generated by the following script

```

ssl_tls12_server: fix potential NULL-dereferencing if local certifica…
 2022-08-19 20:22:59 +01:00
Leonid Rozenboim 19e5973566 mbedtls_ssl_check_curve prevent potential NULL pointer dereferencing 
Avoid the shorthand practice of the form 'x = func(foo)->bar' which
exposes the code to NULL pointer de-referencing when the 'func()'
returns a NULL pointer.

The first chunk is for when the curve group code is not recognized by
the library, and is cleanly rejected if offered.

The second chunk addresses the unlikely case of an internal error:
if 'mbedtls_pk_can_do()' returns TRUE, it should rule out
'mbedtls_pk_ec()' returning a NULL, unless there is a regression.

Janos Follath b7a88eca42 Bignum: Apply naming conventions 
Numbers:

- A, B for mbedtls_mpi_uint* operands
- a, b for mbedtls_mpi_uint operands
- X or x for result
- HAC references where applicable

Lengths:

- Reserve size or length for length/size in bytes or byte buffers.
- For length of mbedtls_mpi_uint* buffers use limbs
- Length parameters are qualified if possible (eg. input_length or
  a_limbs)

Setup functions:

- The parameters match the corresponding structure member's name
- The structure to set up is a standard lower case name even if in other
  functions different naming conventions would apply

Scope of changes/conventions:

- bignum_core
- bignum_mod
- bignum_mod_raw

Przemek Stekiel 76b753bbb7 Change the dependencies in pem.c to xxx_BASED_ON_USE_PSA and related files 
This is done to be able to bild test_psa_crypto_config_accel_hash component where MD5 is only available accelerated (PSA_WANT_ALG_MD5 is enabled and MBEDTLS_MD5_C is disabled) but MBEDTLS_USE_PSA_CRYPTO is disabled.
So the build should not attempt to enable pem_pbkdf1.
