The PSA subsystem may consume global resources. It currently doesn't
consume any heap when no keys are registered, but it may do so in the
future. It does consume mutexes, which are reported as leaks when
mutex usage checking is enabled.

Test hook failure checks may print information to stdout, which messes
up the usage of query_config mode. Nothing interesting happens in
query_config mode anyway, so that's no loss.

Create utility functions to set up test hooks and report errors that
the test hooks might detect. Call them in ssl_client2 and ssl_server2.
Test hooks are potentially enabled by compiling with
MBEDTLS_TEST_HOOKS.
This commit only sets up the functions. It doesn't make them do
anything yet.

Currently, MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG is tested with a dummy
insecure implementation of mbedtls_psa_external_get_random. This
function needs to be explicitly enabled at runtime. This needs to
happen when the PSA external RNG is used, which currently is the case
in SSL test programs only when MBEDTLS_USE_PSA_CRYPTO is enabled.

In ssl_client2 and ssl_server2, to generate random data, go through a
level of indirection provided by ssl_test_lib. This way the programs
don't depend on a particular choice of RNG implementation, and only
ssl_test_lib.{h,c} explicitly reference CTR_DRBG.

PSA and SSL programs are PSA clients thus should use
psa_key_id_t as the type for key identifiers, not
mbedtls_svc_key_id_t.
As a consequence, PSA, ssl_server2 and ssl_client2
programs cannot compile and must not be compiled if
MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER is defined.
Thus, add MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
compilation guard to those programs.

The example application programs/ssl/ssl_server2 allows the
configuration of up to two CRTs through the command line
parameters
- crt_file, key_file
- crt_file2, key_file2.
However, password protected key files are not supported.
This commit adds command line options
- key_pwd
- key_pwd2
which allow to specify passwords for the key files specified
in key_file and key_file2, respectively.
1. When `ssl_server2` export key functionality fails,
don't exit the server, but reset it, to have the
server recover for next connection.
2. Add text filters for `export keys functionality` test in ssl-opt.sh
to check for additional output, to verify if the export suceeded.
This was discovered in the `ssl-opt.sh` script, where the server exited,
before the test tried to kill the server priocess, resulting in a
`kill: No such process` message.

Since the server might want to have a different maximum fragment length
for the outgoing messages than the negotiated one - introduce a new way of
computing it. This commit also adds additional ssl-opt.sh tests ensuring
that the maximum fragment lengths are set as expected.
mbedtls_ssl_get_max_frag_len() is now a deprecated function,
being an alias to mbedtls_ssl_get_output_max_frag_len(). The behaviour
of this function is the same as before.

* ChangeLog: add/add conflict. Resolve by using the usual section order.
Rename identifiers containing double-underscore (`__`) to avoid `__`.
The reason to avoid double-underscore is that all identifiers
containing double-underscore are reserved in C++. Rename all such
identifiers that appear in any public header, including ssl_internal.h
which is in principle private but in practice is installed with the
public headers.
This commit makes check-names.sh pass.

If `context_buf = mbedtls_calloc( 1, buf_len )` failed,
`context_buf_len` was not initialized. Noticed by
`gcc -Os -Werror=maybe-uninitialized`.
This was only a problem in ssl_server2 (a test program), only with
MBEDTLS_SSL_CONTEXT_SERIALIZATION enabled.
Make client_random and server_random const in
mbedtls_ssl_export_keys_ext_t, so that the key exporter is discouraged
from modifying the client/server hello.
Update examples and tests use const for hello.random as well, to ensure
that the export callbacks are of the proper type.
Fixes#2759
This commit adds command line options
- nss_keylog=0/1
- nss_keylog_file=FILENAME
to the example programs ssl/ssl_client2 and ssl/ssl_server2 which
allow to print and export the session keys in the NSS keylog
for debugging purposes.
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.
* origin/pr/2781:
Documentation fixes according to review
Remove unused label in ssl_client2/ssl_server2
Add missing word in documentation of mbedtls_ssl_check_record()
cli/srv ex: Add dbg msg if record checking gives inconsistent result
Fix minor issues in documentation of mbedtls_ssl_check_record()
State that record checking is DTLS only and doesn't check content type
Update version_features.c
Pass dgrams to mbedtls_ssl_check_record in ssl_client2/server2
Add IO wrappers to ssl_server2 as interm's between NET and SSL layer
Add IO wrappers to ssl_client2 as interm's between NET and SSL layer
Introduce configuration option and API for SSL record checking
This is done to account for platforms, for which we want custom behavior
upon the program termination, hence we call `mbedtls_exit()` instead of
returning from `main()`.
* origin/pr/2697:
Update crypto submodule
Add all.sh component that exercises invalid_param checks
Remove mbedtls_param_failed from programs
Make it easier to define MBEDTLS_PARAM_FAILED as assert
Make test suites compatible with #include <assert.h>
Pass -m32 to the linker as well
Don't systematically rebuild programs
