48f3a3d101 Add NSS keylog support to ssl_server2 and ssl_client2
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.

9b9a790be6 Handle deleting non-existant files on Windows
If we try to delete a non-existant file using del on Windows, as
can happen when running make clean, del will throw an error. Make
the Makefiles more robust by only deleting files if they exist.

13c8e68477 Change requirements for setting timer callback
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.

3309a67996 Fix memory leak in client/server2
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.

a88399c091 Improve demo/testing code in client/server2
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.

afa8f71700 Add new config MBEDTLS_SSL_CONTEXT_SERIALIZATION
This is enabled by default as we generally enable things by default unless
there's a reason not to (experimental, deprecated, security risk).

We need a compile-time option because, even though the functions themselves
can be easily garbage-collected by the linker, implementing them will require
saving 64 bytes of Client/ServerHello.random values after the handshake, that
would otherwise not be needed, and people who don't need this feature
shouldn't have to pay the price of increased RAM usage.

686adb4d54 Normalize spelling to serialiZation
We have explicit recommendations to use US spelling for technical writing, so
let's apply this to code as well for uniformity. (My fingers tend to prefer UK
spelling, so this needs to be fixed in many places.)

26f982f50e Improve save API by always updating olen
This allows callers to discover what an appropriate size is. Otherwise they'd

combination of those).

b5e4e0a395 Add mbedtls_ssl_get_session_pointer()
Avoid useless copy with mbedtls_ssl_get_session() before serialising.

Used in ssl_client2 for testing and demonstrating usage, but unfortunately
that means mbedtls_ssl_get_session() is no longer tested, which will be fixed
in the next commit.

776521aee8 Return from the test and utility examples via exit()
All the core examples have been modified not to return from main
by the means of the return statement, but rather via exit() function,
which was done to make the examples more bare metal friendly.

This commit, for the sake of consistency, introduces the modifications
to the test and utility examples. These, while less likely to be used
in the low level environments, won't suffer from such a change.

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()`.

Conflict resolution:
* `scripts/config.pl`:
  Take the exclusion of `MBEDTLS_PSA_CRYPTO_SE_C` from the API branch.
  Take the removal of `MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C` (obsolete) from
  the development branch.
* `tests/scripts/all.sh`:
  Multiple instances of factoring a sequence of `config.pl` calls into
  a mere `config.pl baremetal` in the development branch, and a change in
  the composition of `baremetal` in the API branch. In each case, take the
  version from development.
* `tests/suites/test_suite_psa_crypto_slot_management.function`:
  A function became non-static in development and disappeared in the API

8dd1690993 Merge remote-tracking branch 'tls/development' into development
Resolve conflicts by performing the following operations:
- Reject changes related to building a crypto submodule, since Mbed
  Crypto is the crypto submodule.
- Reject X.509, NET, and SSL changes.
- Reject changes to README, as Mbed Crypto is a different project from
  Mbed TLS, with a different README.
- Avoid adding mention of ssl-opt.sh in a comment near some modified
  code in include/CMakeLists.txt (around where ENABLE_TESTING as added).
- Align config.pl in Mbed TLS with config.pl in Mbed Crypto where PSA
  options are concerned, to make future merging easier. There is no
  reason for the two to be different in this regard, now that Mbed TLS
  always depends on Mbed Crypto. Remaining differences are only the
  PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option and the absence of X.509,
  NET, and SSL related options in Mbed Crypto's config.pl.
- Align config.h in Mbed Crypto with Mbed TLS's copy, with a few notable
  exceptions:
  - Leave CMAC on by default.
  - Leave storage on by default (including ITS emulation).
  - Avoid documenting the PSA Crypto API as is in beta stage in
    documentation for MBEDTLS_PSA_CRYPTO_C.
  The only remaining differences are a lack of X.509, NET, and SSL
  options in Mbed Crypto's config.h, as well as an additional
  Mbed-Crypto-specific PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option.
  Documentation for the check params feature and related macros is also
  updated to match Mbed TLS's description.
- Reject tests/data_files/Makefile changes to generate DER versions of
  CRTs and keys, as none of those are used by Mbed Crypto tests.
- Add the "no PEM and no filesystem" test to all.sh, without ssl-opt.sh
  run, as Mbed Crypto doesn't have ssl-opt.sh. Also remove use of PSA
  Crypto storage and ITS emulation, since those depend on filesystem
  support.
- Reject addition of test when no ciphersuites have MAC to all.sh, as
  the option being tested, MBEDTLS_SSL_SOME_MODES_USE_MAC, is not
  present in Mbed Crypto.
- Use baremetal config in all.sh, as Mbed Crypto's baremetal
  configuration does exclude the net module (as it doesn't exist in Mbed
  Crypto)
- Reject cmake_subproject_build changes, continuing to link only
  libmbedcrypto.
- Reject changes to visualc and associated templates. Mbed Crypto
  doesn't need additional logic to handle submodule-sourced headers.
- Avoid adding fuzzers from Mbed TLS. The only relevant fuzzers are the
  privkey and pubkey fuzzers, but non-trivial work would be required to
  integrate those into Mbed Crypto (more than is comfortable in a merge
  commit).
- Reject addition of Docker wrappers for compat.sh and ssl-opt.sh, as
  those are not present in Mbed Crypto.
- Remove calls to SSL-related scripts from basic-in-docker.sh

Fix test errors by performing the following:
- Avoid using a link that Doxygen can't seem to resolve in Mbed Crypto,
  but can resolve in Mbed TLS. In documentation for
  MBEDTLS_CHECK_PARAMS, don't attempt to link to MBEDTLS_PARAM_FAILED.

Add the compile time option PSA_PRE_1_0_KEY_DERIVATION. If this is not

Most of the tests regarding key derivation haven't been adapted to the
new API yet and some of them have only been adapted partially. When this
new option is turned off, the tests using the old API and test cases
using the old API of partially adapted tests are skipped.

The sole purpose of this option is to make the transition to the new API
smoother. Once the transition is complete it can and should be removed
along with the old API and its implementation.

3abbcedc68 Remove mbedtls_param_failed from programs
All sample and test programs had a definition of mbedtls_param_failed.
This was necessary because we wanted to be able to build them in a
configuration with MBEDTLS_CHECK_PARAMS set but without a definition
of MBEDTLS_PARAM_FAILED. Now that we activate the sample definition of
MBEDTLS_PARAM_FAILED in config.h when testing with
MBEDTLS_CHECK_PARAMS set, this boilerplate code is no longer needed.

c7ad122f51 Make it easier to define MBEDTLS_PARAM_FAILED as assert
Introduce a new configuration option MBEDTLS_CHECK_PARAMS_ASSERT,
which is disabled by default. When this option is enabled,
MBEDTLS_PARAM_FAILED defaults to assert rather than to a call to
mbedtls_param_failed, and <assert.h> is included.

This fixes #2671 (no easy way to make MBEDTLS_PARAM_FAILED assert)
without breaking backward compatibility. With this change,
`config.pl full` runs tests with MBEDTLS_PARAM_FAILED set to assert,
so the tests will fail if a validation check fails, and programs don't
need to provide their own definition of mbedtls_param_failed().

961e677fe3 UDP proxy: Don't attempt to dissect dgram into records when dropping
To prevent dropping the same message over and over again, the UDP proxy
test application programs/test/udp_proxy _logically_ maintains a mapping
from records to the number of times the record has already been dropped,
and stops dropping once a configurable threshold (currently 2) is passed.

However, the actual implementation deviates from this logical view
in two crucial respects:
- To keep the implementation simple and independent of
  implementations of suitable map interfaces, it only counts how
  many times a record of a given _size_ has been dropped, and
  stops dropping further records of that size once the configurable
  threshold is passed. Of course, this is not fail-proof, but a
  good enough approximation for the proxy, and it allows to use
  an inefficient but simple array for the required map.
- The implementation mixes datagram lengths and record lengths:
  When deciding whether it is allowed to drop a datagram, it
  uses the total datagram size as a lookup index into the map
  counting the number of times a package has been dropped. However,
  when updating this map, the UDP proxy traverses the datagram
  record by record, and updates the mapping at the level of record
  lengths.

Apart from this inconsistency, the introduction of the Connection ID
feature leads to yet another problem: The CID length is not part of
the record header but dynamically negotiated during (potentially
encrypted!) handshakes, and it is hence impossible for a passive traffic
analyzer (in this case our UDP proxy) to reliably parse record headers;
especially, it isn't possible to reliably infer the length of a record,
nor to dissect a datagram into records.

The previous implementation of the UDP proxy was not CID-aware and
assumed that the record length would always reside at offsets 11, 12
in the DTLS record header, which would allow it to iterate through
the datagram record by record. As mentioned, this is no longer possible
for CID-based records, and the current implementation can run into
a buffer overflow in this case (because it doesn't validate that
the record length is not larger than what remains in the datagram).

This commit removes the inconsistency in datagram vs. record length
and resolves the buffer overflow issue by not attempting any dissection
of datagrams into records, and instead only counting how often _datagrams_
of a particular size have been dropped.

There is only one practical situation where this makes a difference:
If datagram packing is used by default but disabled on retransmission
(which OpenSSL has been seen to do), it can happen that we drop a
datagram in its initial transmission, then also drop some of its records
when they retransmitted one-by-one afterwards, yet still keeping the
drop-counter at 1 instead of 2. However, even in this situation, we'll
correctly count the number of droppings from that point on and eventually
stop dropping, because the peer will not fall back to using packing
and hence use stable record lengths.

98aaf25686 Add bad_cid option UDP proxy to insert unexpected CID records
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).

8367ccc03b Allow to configure the stack's behaviour on unexpected CIDs
This commit modifies the CID configuration API mbedtls_ssl_conf_cid_len()
to allow the configuration of the stack's behaviour when receiving an

31f6e372e6 UDP Proxy: Don't drop CID records
ApplicationData records are not protected against loss by DTLS
and our test applications ssl_client2 and ssl_server2 don't
implement any retransmission scheme to deal with loss of the
data they exchange. Therefore, the UDP proxy programs/test/udp_proxy
does not drop ApplicationData records.

With the introduction of the Connection ID, encrypted ApplicationData
records cannot be recognized as such by inspecting the record content
type, as the latter is always set to the CID specific content type for
protected records using CIDs, while the actual content type is hidden
in the plaintext.

To keep tests working, this commit adds CID records to the list of
content types which are protected against dropping by the UDP proxy.

ad4a137965 Add CID configuration API
Context:
The CID draft does not require that the length of CIDs used for incoming
records must not change in the course of a connection. Since the record
header does not contain a length field for the CID, this means that if
CIDs of varying lengths are used, the CID length must be inferred from
other aspects of the record header (such as the epoch) and/or by means
outside of the protocol, e.g. by coding its length in the CID itself.

Inferring the CID length from the record's epoch is theoretically possible
in DTLS 1.2, but it requires the information about the epoch to be present
even if the epoch is no longer used: That's because one should silently drop
records from old epochs, but not the entire datagrams to which they belong
(there might be entire flights in a single datagram, including a change of
epoch); however, in order to do so, one needs to parse the record's content
length, the position of which is only known once the CID length for the epoch
is known. In conclusion, it puts a significant burden on the implementation
to infer the CID length from the record epoch, which moreover mangles record
processing with the high-level logic of the protocol (determining which epochs
are in use in which flights, when they are changed, etc. -- this would normally
determine when we drop epochs).

Moreover, with DTLS 1.3, CIDs are no longer uniquely associated to epochs,
but every epoch may use a set of CIDs of varying lengths -- in that case,
it's even theoretically impossible to do record header parsing based on
the epoch configuration only.

We must therefore seek a way for standalone record header parsing, which
means that we must either (a) fix the CID lengths for incoming records,
or (b) allow the application-code to configure a callback to implement
an application-specific CID parsing which would somehow infer the length
of the CID from the CID itself.

Supporting multiple lengths for incoming CIDs significantly increases
complexity while, on the other hand, the restriction to a fixed CID length
for incoming CIDs (which the application controls - in contrast to the
lengths of the CIDs used when writing messages to the peer) doesn't
appear to severely limit the usefulness of the CID extension.

Therefore, the initial implementation of the CID feature will require
a fixed length for incoming CIDs, which is what this commit enforces,
in the following way:

In order to avoid a change of API in case support for variable lengths
CIDs shall be added at some point, we keep mbedtls_ssl_set_cid(), which
includes a CID length parameter, but add a new API mbedtls_ssl_conf_cid_len()
which applies to an SSL configuration, and which fixes the CID length that
any call to mbetls_ssl_set_cid() which applies to an SSL context that is bound
to the given SSL configuration must use.

While this creates a slight redundancy of parameters, it allows to
potentially add an API like mbedtls_ssl_conf_cid_len_cb() later which
could allow users to register a callback which dynamically infers the
length of a CID at record header parsing time, without changing the
rest of the API.

Adapt tests in all.sh:
- tests with submodule enabled (default) no longer need to enable it

all other test cases in this script
- tests with submodule disabled (old default) now need to disable it
  explicitly, and execute some runtime tests, as those are no longer tested
anywhere else in this script

Adapt documentation in Readme: remove the section "building with submodule"
and replace it with a new section before the other building sections.
Purposefully don't document how to build not from the submodule, as that
option is going away soon.

which is key derivation, but we no longer use the generator
terminology so this reason no longer applies.

a99d3fbd05 Rename generator functions to psa_key_derivation_xxx
Generators are mostly about key derivation (currently: only about key
derivation). "Generator" is not a commonly used term in cryptography.
So favor "derivation" as terminology. Call a generator a key
derivation operation structure, since it behaves like other multipart
operation structures. Furthermore, the function names are not fully
consistent.

In this commit, I rename the functions to consistently have the prefix
"psa_key_derivation_". I used the following command:

    perl -i -pe '%t = (
        psa_crypto_generator_t => "psa_key_derivation_operation_t",
        psa_crypto_generator_init => "psa_key_derivation_init",
        psa_key_derivation_setup => "psa_key_derivation_setup",
        psa_key_derivation_input_key => "psa_key_derivation_input_key",
        psa_key_derivation_input_bytes => "psa_key_derivation_input_bytes",
        psa_key_agreement => "psa_key_derivation_key_agreement",
        psa_set_generator_capacity => "psa_key_derivation_set_capacity",
        psa_get_generator_capacity => "psa_key_derivation_get_capacity",
