Gilles Peskine 6331d78675 Don't use the printf format %zd
We target C89 libc, so don't use %zd or %zu. Just use %u, and make
slot numbers `unsigned` for simplicity.

Gilles Peskine 3f3ada8839 Fix memory leak in ssl_server2 with SNI + async callback
In ssl_server2, the private key objects are normally local variables
of the main function. However this does not hold for private keys in
the SNI configuration. When async callbacks are used, the test code
transfers the ownership of the private keys to the async callbacks.
Therefore the test code must free the SNI private keys through the
async callbacks (but it must not free the straight private keys this
way since they are not even heap-allocated).

Gilles Peskine 157f6d8f74 SNI + SSL async callback: make all keys async
When testing async callbacks with SNI, make all the keys async, not
just the first one. Otherwise the test is fragile with respect to
whether a key is used directly or through the async callbacks.

Jaeden Amero e9ecf00007 aes: Remove AES-XEX
AES-XEX is a building block for other cryptographic standards and not yet a
standard in and of itself. We'll just provide the standardized AES-XTS
algorithm, and not AES-XEX. The AES-XTS algorithm and interface provided
can be used to perform the AES-XEX algorithm when the length of the input
is a multiple of the AES block size.

Aorimn 5f77801ac3 Implement AES-XTS mode
XTS mode is fully known as "xor-encrypt-xor with ciphertext-stealing".
This is the generalization of the XEX mode.
This implementation is limited to an 8-bits (1 byte) boundary, which
doesn't seem to be what was thought considering some test vectors [1].

This commit comes with tests, extracted from [1], and benchmarks.
Although, benchmarks aren't really nice here, as they work with a buffer
of a multiple of 16 bytes, which isn't a challenge for XTS compared to
XEX.

Manuel Pégourié-Gonnard 558da9c3fe Make SSL error code more generic
It's undesirable to have users of the SSL layer check for an error code
specific to a lower-level layer, both out of general layering principles, and
also because if we later make another crypto module gain resume capabilities,
we would need to change the contract again (checking for a new module-specific
error code).

Manuel Pégourié-Gonnard da19f4c79f Merge branch 'development' into iotssl-1260-non-blocking-ecc-restricted
Summary of merge conflicts:

include/mbedtls/ecdh.h -> documentation style
include/mbedtls/ecdsa.h -> documentation style
include/mbedtls/ecp.h -> alt style, new error codes, documentation style
include/mbedtls/error.h -> new error codes
library/error.c -> new error codes (generated anyway)
library/ecp.c:
    - code of an extracted function was changed
library/ssl_cli.c:
    - code addition on one side near code change on the other side
      (ciphersuite validation)
library/x509_crt.c -> various things
    - top fo file: helper structure added near old zeroize removed
    - documentation of find_parent_in()'s signature: improved on one side,
      added arguments on the other side
    - documentation of find_parent()'s signature: same as above
    - verify_chain(): variables initialised later to give compiler an
      opportunity to warn us if not initialised on a code path
    - find_parent(): funcion structure completely changed, for some reason git
      tried to insert a paragraph of the old structure...
    - merge_flags_with_cb(): data structure changed, one line was fixed with a
      cast to keep MSVC happy, this cast is already in the new version
    - in verify_restratable(): adjacent independent changes (function
      signature on one line, variable type on the next)
programs/ssl/ssl_client2.c:
    - testing for IN_PROGRESS return code near idle() (event-driven):

Manuel Pégourié-Gonnard 3dc62a0a9b chachapoly: force correct mode for integrated API
Allowing DECRYPT with crypt_and_tag is a risk as people might fail to check

Manuel Pégourié-Gonnard b1ac5e7842 poly1305: adjust parameter order
This module used (len, pointer) while (pointer, len) is more common in the
rest of the library, in particular it's what's used in the CMAC API that is
very comparable to Poly1305, so switch to (pointer, len) for consistency.

Manuel Pégourié-Gonnard dca3a5d884 Rename aead_chacha20_poly1305 to chachapoly
While the old name is explicit and aligned with the RFC, it's also very long,
so with the mbedtls_ prefix prepended we get a 31-char prefix to each
identifier, which quickly conflicts with our 80-column policy.

The new name is shorter, it's what a lot of people use when speaking about
that construction anyway, and hopefully should not introduce confusion at
it seems unlikely that variants other than 20/1305 be standardised in the
foreseeable future.

Simon Butcher 6fd96addf4 Change the default IP addresses for DTLS samples
Changes the IP address to bind to for dtls_server.c to be "::" or optionally
"0.0.0.0" if the preprocessor symbol FORCE_IPV4 is defined.

Also changes the destinaton IP address for dtls_client.c to be "::1" or if
FORCE_IPV4 symbol is defined "127.0.0.1".

This change allows on compilation dtls_server.c and dtls_client.c to both be
compiled to use either IPv4 or IPv6 so out of the box they will work together
without problem, and to avoid dtls_server.c binding to IPv6 and dtls_client.c
binding to IPv4.

Gilles Peskine 26d01bcb5c Async callback: use mbedtls_pk_check_pair to compare keys
In the current test code, the object that is used as a public key in
the certificate also contains a private key. However this is because
of the way the stest code is built and does not demonstrate the API in
a useful way. Use mbedtls_pk_check_pair, which is not what real-world
code would do (since the private key would typically be in an external
cryptoprocessor) but is a more representative placeholder.

Gilles Peskine 1febfef561 Rename mbedtls_ssl_async_{get,set}_data for clarity

Gilles Peskine 807d74a062 SSL async callback: cert is not always from mbedtls_ssl_conf_own_cert
The certificate passed to async callbacks may not be the one set by
mbedtls_ssl_conf_own_cert. For example, when using an SNI callback,
it's whatever the callback is using. Document this, and add a test
case (and code sample) with SNI.

Gilles Peskine c912572a7f ssl_server2: merge redundant async_private_error=resume/pk
Testing the case where the resume callback returns an error at the
beginning and the case where it returns an error at the end is
redundant. Keep the test after the output has been produced, to
validate that the product does not use even a valid output if the
return value is an error code.

Gilles Peskine d3268834f3 Document what the SSL async sign callback needs to do with RSA
Document how the SSL async sign callback must treat its md_alg and
hash parameters when doing an RSA signature: sign-the-hash if md_alg
is nonzero (TLS 1.2), and sign-the-digestinfo if md_alg is zero
(TLS <= 1.1).

In ssl_server2, don't use md_alg=MBEDTLS_MD_NONE to indicate that
ssl_async_resume must perform an encryption, because md_alg is also
MBEDTLS_MD_NONE in TLS <= 1.1. Add a test case to exercise this
case (signature with MBEDTLS_MD_NONE).

Gilles Peskine df13d5c7a6 Pass the SSL context to async callbacks
When a handshake step starts an asynchronous operation, the
application needs to know which SSL connection the operation is for,
so that when the operation completes, the application can wake that
connection up. Therefore the async start callbacks need to take the
SSL context as an argument. It isn't enough to let them set a cookie
in the SSL connection, the application needs to be able to find the
right SSL connection later.

Also pass the SSL context to the other callbacks for consistency. Add
a new field to the handshake that the application can use to store a
per-connection context. This new field replaces the former
context (operation_ctx) that was created by the start function and
passed to the resume function.

Add a boolean flag to the handshake structure to track whether an
asynchronous operation is in progress. This is more robust than
relying on the application to set a non-null application context.

Gilles Peskine b44692f126 Merge branch 'mbedtls_ssl_get_key_exchange_md_ssl_tls-return_hashlen' into tls_async_server-2.9
Conflict resolution:
* ChangeLog: put the new entry from my branch in the proper place.
* include/mbedtls/error.h: counted high-level module error codes again.
* include/mbedtls/ssl.h: picked different numeric codes for the
  concurrently added errors; made the new error a full sentence per
  current standards.
* library/error.c: ran scripts/generate_errors.pl.
* library/ssl_srv.c:
    * ssl_prepare_server_key_exchange "DHE key exchanges": the conflict
      was due to style corrections in development
      (4cb1f4d49c) which I merged with
      my refactoring.
    * ssl_prepare_server_key_exchange "For key exchanges involving the
      server signing", first case, variable declarations: merged line
      by line:
        * dig_signed_len: added in async
        * signature_len: removed in async
        * hashlen: type changed to size_t in development
        * hash: size changed to MBEDTLS_MD_MAX_SIZE in async
        * ret: added in async
    * ssl_prepare_server_key_exchange "For key exchanges involving the
      server signing", first cae comment: the conflict was due to style
      corrections in development (4cb1f4d49c)
      which I merged with my comment changes made as part of refactoring
      the function.
    * ssl_prepare_server_key_exchange "Compute the hash to be signed" if
      `md_alg != MBEDTLS_MD_NONE`: conflict between
      ebd652fe2d
      "ssl_write_server_key_exchange: calculate hashlen explicitly" and
      46f5a3e9b4 "Check return codes from
      MD in ssl code". I took the code from commit
      ca1d742904 made on top of development
      which makes mbedtls_ssl_get_key_exchange_md_ssl_tls return the
      hash length.
* programs/ssl/ssl_server2.c: multiple conflicts between the introduction
  of MBEDTLS_ERR_SSL_ASYNC_IN_PROGRESS and new auxiliary functions and
  definitions for async support, and the introduction of idle().
    * definitions before main: concurrent additions, kept both.
    * main, just after `handshake:`: in the loop around
      mbedtls_ssl_handshake(), merge the addition of support for
      MBEDTLS_ERR_SSL_ASYNC_IN_PROGRESS and SSL_ASYNC_INJECT_ERROR_CANCEL
      with the addition of the idle() call.
    * main, if `opt.transport == MBEDTLS_SSL_TRANSPORT_STREAM`: take the
      code from development and add a check for
      MBEDTLS_ERR_SSL_ASYNC_IN_PROGRESS.
    * main, loop around mbedtls_ssl_read() in the datagram case:
      take the code from development and add a check for
      MBEDTLS_ERR_SSL_ASYNC_IN_PROGRESS; revert to a do...while loop.
    * main, loop around mbedtls_ssl_write() in the datagram case:
      take the code from development and add a check for
      MBEDTLS_ERR_SSL_ASYNC_IN_PROGRESS; revert to a do...while loop.

Previously, the idling loop in ssl_server2 didn't check whether
the underlying call to mbedtls_net_poll signalled that the socket
became invalid. This had the consequence that during idling, the
server couldn't be terminated through a SIGTERM, as the corresponding
handler would only close the sockets and expect the remainder of
the program to shutdown gracefully as a consequence of this.
This was subsequently attempted to be fixed through a change
in ssl-opt.sh by terminating the server through a KILL signal,
which however lead to other problems when the latter was run
under valgrind.

This commit changes the idling loop in ssl_server2 and ssl_client2
to obey the return code of mbedtls_net_poll and gracefully shutdown
if an error occurs, e.g. because the socket was closed.

As a consequence, the server termination via a KILL signal in
ssl-opt.sh is no longer necessary, with the previous `kill; wait`
pattern being sufficient. The commit reverts the corresponding
change.

Brendan Shanks e61514d70d benchmark: Fix incompatibility with C89 compilers
Initializing arrays using non-constant expressions is not permitted in
C89, and was causing errors when compiling with Metrowerks CodeWarrior
(for classic MacOS) in C89 mode. Clang also produces a warning when
compiling with '-Wc99-extensions':

test/benchmark.c:670:42: warning: initializer for aggregate is not a compile-time constant [-Wc99-extensions]
        const unsigned char *dhm_P[] = { dhm_P_2048, dhm_P_3072 };
                                         ^~~~~~~~~~

                                         ^~~~~~~~~~

Declaring the arrays as 'static' makes them constant expressions.

Manuel Pégourié-Gonnard 4fa619fe56 Fix race condition in error printing in ssl_server2.c
The race goes this way:
1. ssl_recv() succeeds (ie no signal received yet)
2. processing the message leads to aborting handshake with ret != 0
3. reset ret if we were signaled
4. print error if ret is still non-zero
5. go back to net_accept() which can be interrupted by a signal
We print the error message only if the signal is received between steps 3 and
5, not when it arrives between steps 1 and 3.

This can cause failures in ssl-opt.sh where we check for the presence of "Last
error was..." in the server's output: if we perform step 2, the client will be
notified and exit, then ssl-opt.sh will send SIGTERM to the server, but if it
didn't get a chance to run and pass step 3 in the meantime, we're in trouble.

The purpose of step 3 was to avoid spurious "Last error" messages in the
output so that ssl-opt.sh can check for a successful run by the absence of
that message. However, it is enough to suppress that message when the last
error we get is the one we expect from being interrupted by a signal - doing
more could hide real errors.

Also, improve the messages printed when interrupted to make it easier to
distinguish the two cases - this could be used in a testing script wanted to
check that the server doesn't see the client as disconnecting unexpectedly.

Hanno Becker d4d60579e4 Address issues found by coverity
1) `mbedtls_rsa_import_raw` used an uninitialized return
   value when it was called without any input parameters.
   While not sensible, this is allowed and should be a
   succeeding no-op.

2) The MPI test for prime generation missed a return value
   check for a call to `mbedtls_mpi_shift_r`. This is neither
   critical nor new but should be fixed.

3) Both the RSA keygeneration example program and the
   RSA test suites contained code initializing an RSA context
   after a potentially failing call to CTR DRBG initialization,
   leaving the corresponding RSA context free call in the
   cleanup section of the respective function orphaned.
   While this defect existed before, Coverity picked up on
   it again because of newly introduced MPI's that were
   also wrongly initialized only after the call to CTR DRBG
   init. The commit fixes both the old and the new issue
   by moving the initializtion of both the RSA context and
   all MPI's prior to the first potentially failing call.

to `unsigned int` that could come with a loss of data. This commit
re-types the corresponding struct field `ctx_buffer::len` to `size_t`.
Also, the function `ctx_buffer_append` has an integer return value
which is supposed to be the (positive) length of the appended data
on success, and a check is inserted that the data to be appended does
not exceed MAX_INT in length.

Hanno Becker fbb0b701e4 Corrupt application data in the beginning instead of the end in UDP proxy
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.

Hanno Becker f65ca329b6 Introduce UDP proxy wrapper script
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.

directly on a buffer containing plain text. Although the text explains
that it should be the message hash it still can be confusing.

Any misunderstandings here are potentially very dangerous, because ECDSA
truncates the message hash if necessary and this can lead to trivial
signature forgeries if the API is misused and the message is passed
directly to the function without hashing.

This commit adds a hash computation step to the ecdsa.c sample
application and clarification to the doxygen documentation of the
ECDSA functions involved.

Andres AG 0b736db0f3 Remove use of inttypes.h in MSVC from ssl_server2
The sample application programs/ssl/ssl_server2.c was previously
modifies to use inttypes.h to parse a string to a 64-bit integer.
However, MSVC does not support C99, so compilation fails. This
patch modifies the sample app to use the MSVC specific parsing
functions instead of inttypes.h.

Andres AG 692ad84e5c Add DTLS test to check 6 byte record ctr is cmp
Add a test to ssl-opt.sh to ensure that in DTLS a 6 byte record counter
is compared in ssl_check_ctr_renegotiate() instead of a 8 byte one as in
the TLS case. Because currently there are no testing facilities to check
that renegotiation routines are triggered after X number of input/output
messages, the test consists on setting a renegotiation period that
cannot be represented in 6 bytes, but whose least-significant byte is 2.
If the library behaves correctly, the renegotiation routines will be
executed after two exchanged.

Simon Butcher c58d7b4074 Merge fix for X.509 compatibility issues 2016-10-13 15:54:03 +01:00
Simon Butcher e19acd5e79 Add extra compilation conditions to X.509 samples
The sample applications programs/pkey/cert_req.c and
programs/pkey/cert_write.c use the library functions
mbedtls_pk_write_csr_pem() and mbedtls_pk_write_crt_pem() respectively which
are dependent on the configuration option MBEDTLS_PEM_WRITE_C. If the option
isn't defined the build breaks.

This change adds the compilation condition MBEDTLS_PEM_WRITE_C to these
sample application.

lastn is not used with the cipher layer as it already provides padding
and understanding of length of the original data.

Instead of polling the hardware entropy source a single time and
comparing the output with itself, the source is polled at least twice

Andres AG b34e42e69e Add a new self test to entropy module
The self test is a quick way to check at startup whether the entropy
sources are functioning correctly. The self test only polls 8 bytes
from the default entropy source and performs the following checks:

- The bytes are not all 0x00 or 0xFF.
- The hardware does not return an error when polled.
- The entropy does not provide data in a patter. Only check pattern
  at byte, word and long word sizes.
