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.
This commit adds the following command line options to programs/x509/cert_write:
- version (val 1, 2, 3): Set the certificate's version (v1, v2, v3)
- authority_identifier (val 0, 1): Enable or disable the addition of the
authority identifier extension.
- subject_identifier (val 0, 1): Enable or disable the addition of the
subject identifier extension.
- basic_constraints (val 0, 1): Enable or disable the addition of the
basic constraints extension.
- md (val MD5, SHA1, SHA256, SHA512): Set the hash function used
when creating the CRT.
The AES sample application programs/aes/aescrypt2 could miss zeroizing
the stack-based key buffer in case of an error during operation. This
commit fixes this and also clears another temporary buffer as well as
all command line arguments (one of which might be the key) before exit.

This commit adds four tests to tests/ssl-opt.sh:
(1) & (2): Check behaviour of optional/required verification when the
trusted CA chain is empty.
(3) & (4): Check behaviour of optional/required verification when the
client receives a server certificate with an unsupported curve.
In the TLS test client, allow SHA-1 as a signature hash algorithm.
Without this, the renegotation tests failed.
A previous commit had allowed SHA-1 via the certificate profile but
that only applied before the initial negotiation which includes the
signature_algorithms extension.
SHA-1 is now disabled by default in the X.509 layer. Explicitly enable
it in our tests for now. Updating all the test data to SHA-256 should
be done over time.
Adding the CA suppression list option to the 'ssl_server2' sample
program is a prerequisite for adding tests for this feature to the
integration test suite (ssl-opt.sh).
In the ecdsa.c sample application we don't use hashing, we use ecdsa
directly on a buffer containing plain text. Although the text explains
that it should be the message hash it still can be confusing.
Any misunderstandings here are potentially very dangerous, because ECDSA
truncates the message hash if necessary and this can lead to trivial
signature forgeries if the API is misused and the message is passed
directly to the function without hashing.
This commit adds a hash computation step to the ecdsa.c sample
application and clarification to the doxygen documentation of the
ECDSA functions involved.
The sample application programs/ssl/ssl_server2.c was previously
modifies to use inttypes.h to parse a string to a 64-bit integer.
However, MSVC does not support C99, so compilation fails. This
patch modifies the sample app to use the MSVC specific parsing
functions instead of inttypes.h.
use mbedtls_pk_check_pair to verify if issuer certificate and issuer key match,
instad of explicitely comparing RSA public component.
Raised and fix suggested by dbedev in #777
Add a test to ssl-opt.sh to ensure that in DTLS a 6 byte record counter
is compared in ssl_check_ctr_renegotiate() instead of a 8 byte one as in
the TLS case. Because currently there are no testing facilities to check
that renegotiation routines are triggered after X number of input/output
messages, the test consists on setting a renegotiation period that
cannot be represented in 6 bytes, but whose least-significant byte is 2.
If the library behaves correctly, the renegotiation routines will be
executed after two exchanged.
The sample applications programs/pkey/cert_req.c and
programs/pkey/cert_write.c use the library functions
mbedtls_pk_write_csr_pem() and mbedtls_pk_write_crt_pem() respectively which
are dependent on the configuration option MBEDTLS_PEM_WRITE_C. If the option
isn't defined the build breaks.
This change adds the compilation condition MBEDTLS_PEM_WRITE_C to these
sample application.
The sample application programs/pkey/gen_key.c uses the library function
mbedtls_pk_write_key_pem() which is dependent on the configuration option
MBEDTLS_PEM_WRITE_C. If the option isn't defined the build breaks.
This change adds the compilation condition MBEDTLS_PEM_WRITE_C to the gen_key.c
sample application.
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'.

* Fix crypt_and_hash to support decrypting GCM encrypted files
* Fix documentation in crypt_and_hash for the generic case
* Remove unused lastn from crypt_and_hash
lastn is not used with the cipher layer as it already provides padding
and understanding of length of the original data.
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.
Separates platform time abstraction into it's own header from the
general platform abstraction as both depend on different build options.
(MBEDTLS_PLATFORM_C vs MBEDTLS_HAVE_TIME)
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.

This commit fixes the `Destination buffer is too small` error returned
by `mbedtls_cert_write` command when the values of `subject_name` or
`issuer_name` parameters exceed 128 characters.
I have increased the size of these varaibles from 128 to 256 characters,
but I don't know if it's the best way to solve this issue...
Fixes#315.
- interrupt the connection abruptly (no close_notify)
- reconnect from the same port while server sill has an active connection from
this port.
Some real-world clients do that, see section 4.2.8 of RFC 6347.
This is not very useful for TLS as mbedtls_ssl_write() will automatically
fragment and return the length used, and the application should check for that
anyway, but this is useful for DTLS where mbedtls_ssl_write() returns an
error, and the application needs to be able to query the maximum length
instead of just guessing.
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
- Only the server needs to generate/parse tickets
- Only the client needs to store them
Also adjust prototype of ssl_conf_session_tickets() while at it.
GCC 4.9 with ASan + UBSan on OS X complains that we were casting to int from a
wider integer type. Anyway, this cast is totally non-portable (pthread_t could
even be structure), switching to long gets rid of the warning...
Initially thought it would be per-connection, but since max_version is in conf
too, and you need to lower that for a fallback connection, the fallback flag
should be in the same place
