This commit modifies the example programs ssl_client2 and ssl_server2
to allocate various structures on the heap instead of the stack. This
allows more fine-grained memory usage tracking via valgrind massif.
So far, ssl_client2 and ssl_server2 were relying on MBEDTLS_CTR_DRBG_C
being set. This commit adapts them to use HMAC DRBG in case CTR DRBG
is disabled in the configuration.
Note that disabling CTR DRBG in favor of HMAC DRBG can be useful on
constrained systems because Mbed TLS' HMAC DRBG is slightly smaller,
and moreover needed anyway as part of deterministic ECDSA.
Now function mbedtls_ssl_set_hostname is compile-time configurable
in config.h with define MBEDTLS_X509_REMOVE_HOSTNAME_VERIFICATION.
This affects to many x509 API's. See config.h for details.
The code wants timer callbacks to be set (checked in fetch_input()), and can't
easily check whether we're using nbio, so it seems easier to require the
callbacks to be always set rather than only with nbio as was previously done.
context_buf was never free()d. Moreover, since we want to free it on error
paths as well, and even properly zeroize it in order to demonstrate good
memory hygiene, we need to make it and its length main()-scoped.
Previously it was missing reset in case 1, and in case 2 the code was never
executed as the option value was reset to 0.
Tighten checking of return values of save(NULL, 0) now that it works.
Also, improve the printed output as well as the comments.
I checked manually that everything now works and fail in the expected way:
save, reset-or-reinit and load all succeed, but the subsequent read or write
fails.
This commit introduces the option MBEDTLS_SSL_CONF_SINGLE_HASH
which can be used to register a single supported signature hash
algorithm at compile time. It replaces the runtime configuration
API mbedtls_ssl_conf_sig_hashes() which allows to register a _list_
of supported signature hash algorithms.
In contrast to other options used to hardcode configuration options,
MBEDTLS_SSL_CONF_SINGLE_HASH isn't a numeric option, but instead it's
only relevant if it's defined or not. To actually set the single
supported hash algorithm that should be supported, numeric options
MBEDTLS_SSL_CONF_SINGLE_HASH_TLS_ID
MBEDTLS_SSL_CONF_SINGLE_HASH_MD_ID
must both be defined and provide the TLS ID and the Mbed TLS internal
ID and the chosen hash algorithm, respectively.
This commit introduces the option MBEDTLS_SSL_CONF_SINGLE_EC
which can be used to register a single supported elliptic curve
at compile time. It replaces the runtime configuration API
mbedtls_ssl_conf_curves() which allows to register a _list_
of supported elliptic curves.
In contrast to other options used to hardcode configuration options,
MBEDTLS_SSL_CONF_SINGLE_EC isn't a numeric option, but instead it's
only relevant if it's defined or not. To actually set the single
elliptic curve that should be supported, numeric options
MBEDTLS_SSL_CONF_SINGLE_EC_TLS_ID
MBEDTLS_SSL_CONF_SINGLE_EC_GRP_ID
must both be defined and provide the TLS ID and the Mbed TLS internal
ID and the chosen curve, respectively.
If MBEDTLS_SSL_SINGLE_CIPHERSUITE is enabled, it overwrites
the runtime configuration of supported ciphersuites, which
includes both the configuration API and the fields which are
used to store the configuration. Both are therefore no longer
needed and should be removed for the benefit of code-size,
memory usage, and API clarity (no accidental hiccup of runtime
vs. compile-time configuration possible).
The configuration API mbedtls_ssl_conf_ciphersuites() has
already been removed in case MBEDTLS_SSL_SINGLE_CIPHERSUITE,
and this commit removes the field
mbedtls_ssl_config::ciphersuite_list
which it updates.
This commit introduces an internal zero-cost abstraction layer for
SSL ciphersuites: Instead of addressing ciphersuites via pointers
to instances of mbedtls_ssl_ciphersuite_t and accessing their fields
directly, this commit introduces an opaque type
mbedtls_ssl_ciphersuite_handle_t,
and getter functions
mbedtls_ssl_suite_get_xxx()
operating on ciphersuite handles.
The role of NULL is played by a new macro constant
MBEDTLS_SSL_CIPHERSUITE_INVALID_HANDLE
which results of functions returning handles can be checked against.
(For example, when doing a lookup of a ciphersuite from a peer-provided
ciphersuite ID in the per's Hello message).
The getter functions have the validity of the handle as a precondition
and are undefined if the handle is invalid.
So far, there's only one implementation of this abstraction layer, namely
mbedtls_ssl_ciphersuite_handle_t being mbedtls_ssl_ciphersuite_t const *
and
getter functions being field accesses.
In subsequent commits, however, the abstraction layer will be useful
to save code in the situation where only a single ciphersuite is enabled.

If the ExtendedMasterSecret extension is configured at compile-time
by setting MBEDTLS_SSL_CONF_EXTENDED_MASTER_SECRET and/or
MBEDTLS_SSL_CONF_ENFORCE_EXTENDED_MASTER_SECRET, the runtime
configuration APIs mbedtls_ssl_conf_extended_master_secret()
and mbedtls_ssl_conf_extended_master_secret_enforce() must
either be removed or modified to take no effect (or at most
check that the runtime value matches the hardcoded one, but
that would undermine the code-size benefits the hardcoding
is supposed to bring in the first place).
Previously, the API was kept but modified to have no effect.
While convenient for us because we don't have to adapt example
applications, this comes at the danger of users calling the runtime
configuration API, forgetting that the respective fields are
potentially already hardcoded at compile-time - and hence silently
using a configuration they don't intend to use.
This commit changes the approach to removing the configuration
API in case the respective field is hardcoded at compile-time,
and exemplifies it in the only case implemented so far, namely
the configuration of the ExtendedMasterSecret extension.
It adapts ssl_client2 and ssl_server2 by omitting the call to
the corresponding API if MBEDTLS_SSL_CONF_XXX are defined and
removing the command line parameters for the runtime configuration
of the ExtendedMasterSecret extension.
