All of them are copied from (former) CRT and key files in `tests/data_files`.
For files which have been regenerated since they've been copied to `certs.c`,
update the copy.
Add declarations for DER encoded test CRTs to certs.h
Add DER encoded versions of CRTs to certs.c
fix comment in certs.c
Don't use (signed) char for DER encoded certificates
Consistently use `const char *` for test CRTs regardless of encoding
Remove non-sensical and unused PW variable for DER encoded key
Provide test CRTs in PEM and DER fmt, + pick suitable per config
This commit modifies `certs.h` and `certs.c` to start following the
following pattern for the provided test certificates and files:
- Raw test data is named `NAME_ATTR1_ATTR2_..._ATTRn`
For example, there are
`TEST_CA_CRT_{RSA|EC}_{PEM|DER}_{SHA1|SHA256}`.
- Derived test data with fewer attributes, iteratively defined as one
of the raw test data instances which suits the current configuration.
For example,
`TEST_CA_CRT_RSA_PEM`
is one of `TEST_CA_CRT_RSA_PEM_SHA1` or `TEST_CA_CRT_RSA_PEM_SHA256`,
depending on whether SHA-1 and/or SHA-256 are defined in the current
config.
Add missing public declaration of test key password
Fix signedness and naming mismatches
Further improve structure of certs.h and certs.c
Fix definition of mbedtls_test_cas test CRTs depending on config
Remove semicolon after macro string constant in certs.c
This allows to test PSK-based ciphersuites via ssl_server2 in builds
which have MBEDTLS_X509_CRT_PARSE_C enabled but both MBEDTLS_FS_IO and
MBEDTLS_CERTS_C disabled.

A similar change is applied to the `crt_file` and `key_file` arguments.
This commit adds the command line option 'bad_cid' to the UDP proxy
`./programs/test/udp_proxy`. It takes a non-negative integral value N,
which if not 0 has the effect of duplicating every 1:N CID records
and modifying the CID in the first copy sent.
This is to exercise the stacks documented behaviour on receipt
of unexpected CIDs.
It is important to send the record with the unexpected CID first,
because otherwise the packet would be dropped already during
replay protection (the same holds for the implementation of the
existing 'bad_ad' option).
This commit modifies mbedtls_ssl_get_peer_cid() to also allow passing
NULL pointers in the arguments for the peer's CID value and length, in
case this information is needed.
For example, some users might only be interested in whether the use of
the CID was negotiated, in which case both CID value and length pointers
can be set to NULL. Other users might only be interested in confirming
that the use of CID was negotiated and the peer chose the empty CID,
in which case the CID value pointer only would be set to NULL.
It doesn't make sense to pass a NULL pointer for the CID length but a
non-NULL pointer for the CID value, as the caller has no way of telling
the length of the returned CID - and this case is therefore forbidden.
This commit modifies the CID configuration API mbedtls_ssl_conf_cid_len()
to allow the configuration of the stack's behaviour when receiving an
encrypted DTLS record with unexpected CID.
Currently, the stack silently ignores DTLS frames with an unexpected CID.
However, in a system which performs CID-based demultiplexing before passing
datagrams to the Mbed TLS stack, unexpected CIDs are a sign of something not
working properly, and users might want to know about it.
This commit introduces an SSL error code MBEDTLS_ERR_SSL_UNEXPECTED_CID
which the stack can return in response to an unexpected CID. It will
conditionally be put to use in subsequent commits.
There are two options:
1. Don't set it, and don't use it during record protection,
guarding the respective paths by a check whether TLS or
DTLS is used.
2. Set it to the default value even for TLS, and avoid the
protocol-dependent branch during record protection.
This commit picks option 2.
