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.
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.
