MBEDTLS_PSA_HAS_ITS_IO is not really useful since it doesn't actually
enable anything except the entropy seed file support, which only
requires the ITS interface and not a native implemetation. Remove it.
Since the ITS API has stabilized and we don't plan to make use of more
than ITS, we don't need an abstraction layer between key storage and
key storage over ITS. Merge the ITS code into the generic storage
module.
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.
Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on
SSL and therefore about to be removed, the only consumer of query_config
is the query_compile_time_config test. As such, it makes sense to move
query_config to be next to what uses it.
This commit improves hygiene and formatting of macro definitions
throughout the library. Specifically:
- It adds brackets around parameters to avoid unintended
interpretation of arguments, e.g. due to operator precedence.
- It adds uses of the `do { ... } while( 0 )` idiom for macros that
can be used as commands.
The previous prototype gave warnings are the strings produced by #cond and
__FILE__ are const, so we shouldn't implicitly cast them to non-const.
While at it modifying most example programs:
- include the header that has the function declaration, so that the definition
can be checked to match by the compiler
- fix whitespace
- make it work even if PLATFORM_C is not defined:
- CHECK_PARAMS is not documented as depending on PLATFORM_C and there is
no reason why it should
- so, remove the corresponding #if defined in each program...
- and add missing #defines for mbedtls_exit when needed
The result has been tested (make all test with -Werror) with the following
configurations:
- full with CHECK_PARAMS with PLATFORM_C
- full with CHECK_PARAMS without PLATFORM_C
- full without CHECK_PARAMS without PLATFORM_C
- full without CHECK_PARAMS with PLATFORM_C
Additionally, it has been manually tested that adding
mbedtls_aes_init( NULL );
near the normal call to mbedtls_aes_init() in programs/aes/aescrypt2.c has the
expected effect when running the program.
The sample programs require an additional handler function of
mbedtls_param_failed() to handle any failed parameter validation checks enabled
by the MBEDTLS_CHECK_PARAMS config.h option.
Some sample programs access structure fields directly. Making these work is
desirable in the long term, but these are not essential for the core
functionality in non-legacy mode.
Previously, the UDP proxy could only remember one delayed message
for future transmission; if two messages were delayed in succession,
without another one being normally forwarded in between,
the message that got delayed first would be dropped.
This commit enhances the UDP proxy to allow to delay an arbitrary
(compile-time fixed) number of messages in succession.
Functions time with TIME_AND_TSC() didn't have their return values checked.
I'm not sure whether Coverity complained about existing uses, but it did about
new ones, since we consistently check their return values everywhere but here,
which it rightfully finds suspicious.
So, let's check return values. This probably adds a few cycles to existing
loop overhead, but on my machine (x86_64) the added overhead is less than the
random-looking variation between various runs, so it's acceptable.
Some calls had their own particular error checking; remove that in favour of
the new general solution.

AES-XEX is a building block for other cryptographic standards and not yet a
standard in and of itself. We'll just provide the standardized AES-XTS
algorithm, and not AES-XEX. The AES-XTS algorithm and interface provided
can be used to perform the AES-XEX algorithm when the length of the input
is a multiple of the AES block size.
XTS mode is fully known as "xor-encrypt-xor with ciphertext-stealing".
This is the generalization of the XEX mode.
This implementation is limited to an 8-bits (1 byte) boundary, which
doesn't seem to be what was thought considering some test vectors [1].
This commit comes with tests, extracted from [1], and benchmarks.
Although, benchmarks aren't really nice here, as they work with a buffer
of a multiple of 16 bytes, which isn't a challenge for XTS compared to
XEX.

Allowing DECRYPT with crypt_and_tag is a risk as people might fail to check

This module used (len, pointer) while (pointer, len) is more common in the
rest of the library, in particular it's what's used in the CMAC API that is
very comparable to Poly1305, so switch to (pointer, len) for consistency.
While the old name is explicit and aligned with the RFC, it's also very long,
so with the mbedtls_ prefix prepended we get a 31-char prefix to each
identifier, which quickly conflicts with our 80-column policy.
The new name is shorter, it's what a lot of people use when speaking about
that construction anyway, and hopefully should not introduce confusion at
it seems unlikely that variants other than 20/1305 be standardised in the
foreseeable future.

The idea is to use the simple program that is expected to be modified
rarely to set a breakpoint in a specific line and check that the
function mbedtls_zeroize() does actually set the buffer to 0 and is not
optimised out by the compiler.
Initializing arrays using non-constant expressions is not permitted in
C89, and was causing errors when compiling with Metrowerks CodeWarrior
(for classic MacOS) in C89 mode. Clang also produces a warning when
compiling with '-Wc99-extensions':
test/benchmark.c:670:42: warning: initializer for aggregate is not a compile-time constant [-Wc99-extensions]
const unsigned char *dhm_P[] = { dhm_P_2048, dhm_P_3072 };
^~~~~~~~~~

const unsigned char *dhm_G[] = { dhm_G_2048, dhm_G_3072 };
^~~~~~~~~~
Declaring the arrays as 'static' makes them constant expressions.

The _ext suffix suggests "new arguments", but the new functions have
the same arguments. Use _ret instead, to convey that the difference is
that the new functions return a value.

MSVC rightfully complained that there was some conversion from `size_t`
to `unsigned int` that could come with a loss of data. This commit
re-types the corresponding struct field `ctx_buffer::len` to `size_t`.
Also, the function `ctx_buffer_append` has an integer return value
which is supposed to be the (positive) length of the appended data
on success, and a check is inserted that the data to be appended does
not exceed MAX_INT in length.
Don't mangle arguments containing spaces and other special characters,
pass them unchanged to the proxy or server as applicable.
More robust parsing of server parameters: don't hit on partial words;
use ssl_server2's default values.
Minor style improvements.
The UDP proxy corrupts application data at the end of the datagram. If
there are multiple DTLS records within the same datagram, this leads
to the wrong message being corrupted. This commit always corrupts the
beginning of the message to prevent this.
Overall, the UDP proxy needs reworking if it is supposed to reliably
support multiple records within a single datagram, because it
determines its actions from the type of the first record in the
current datagram only.
This commit provides the new option pack=TIME for the udp proxy
./programs/test/udp_proxy. If used, udp packets with the same
destination will be queued and concatenated for up to TIME
milliseconds before being delivered.
This is useful to test how mbed TLS's deals with multiple DTLS records
within a single datagram.
This commit introduces the script `programs/test/udp_proxy_wrapper.sh` which can
be used to wrap the SSL server binary `programs/ssl/ssl_server2` by the UDP
proxy application `programs/test/udp_proxy` while maintaining the same
interface from the command line.
Specifically, given UDP proxy arguments ARGS_UDP and SSL server arguments
ARGS_SSL, the command line
> ./udp_proxy_wrapper.sh ARGS_UDP -- ARGS_SSL
behaves like
> ./ssl_server2 ARGS_SSL
wrapped by
> ./udp_proxy ARGS_UDP
The motivation and benefit of this is that scripts like `ssl-opt.sh` can be used
with the server command line `P_SRV` modified to `./udp_proxy_wrapper.sh
ARGS_UDP -- DEFAULT_ARGS_SSL` which will result in all tests being executed for
an SSL server behind a UDP proxy.
The library/net.c and its corresponding include/mbedtls/net.h file are
renamed to library/net_sockets.c and include/mbedtls/net_sockets.h
respectively. This is to avoid naming collisions in projects which also
have files with the common name 'net'.
Instead of polling the hardware entropy source a single time and
comparing the output with itself, the source is polled at least twice
and make sure that the separate outputs are different.
The self test is a quick way to check at startup whether the entropy
sources are functioning correctly. The self test only polls 8 bytes
from the default entropy source and performs the following checks:
- The bytes are not all 0x00 or 0xFF.
- The hardware does not return an error when polled.
- The entropy does not provide data in a patter. Only check pattern
at byte, word and long word sizes.
Now counts and displays the number of test suites executed, which can vary
depending on build configurations.
All tests are now executed as this is a sample and test program, rather than
exit on first failure.
Exit code now restricted to SUCCESS or FAILURE.
Our Windows implementation based on vsnprintf_s( ..., _TRUNCATE ) sometimes
writes *two* terminating NULLs. Allow for that, but obviously bytes past the
end of the buffer mustn't be touched.
- Added in each tests program to be sure they are run (putting them in a test
suite/function specific to the platform layer would cause them to be skipped
when PLATFORM_C is not defined).
- Platforms have already moved from a standard to a broken snprintf in the
past [1], so make sure to catch that if it ever happens again.
[1]: http://sourceforge.net/p/mingw-w64/mailman/message/31241434/
Things that are not guaranteed by the standard but should be true of all
platforms of interest to us:
- 8-bit chars
- NULL pointers represented by all-bits-zero
