Janos Follath 52735ef2fe ECDH: Prevent direct access in non-legacy mode
Some sample programs access structure fields directly. Making these work is
desirable in the long term, but these are not essential for the core
functionality in non-legacy mode.

when signing the CSR.

Manuel Pégourié-Gonnard 6346a75dfb Merge branch 'development' into iotssl-1260-non-blocking-ecc-restricted
* development:
  ssl-opt.sh: change expected output for large srv packet test with SSLv3
  Adapt ChangeLog
  Fix bug in SSL ticket implementation removing keys of age < 1s
  ssl-opt.sh: Add DTLS session resumption tests
  Add ChangeLog entry
  Fix typo
  Fix hmac_drbg failure in benchmark, with threading
  Remove trailing whitespace
  Remove trailing whitespace
  ssl_server2: add buffer overhead for a termination character
  Add missing large and small packet tests for ssl_server2
  Added buffer_size and response_size options for ssl-server2. Added appropriate tests.

Solving a conflict in tests/ssl-opt.sh: two set of tests were added at the
same place (just after large packets):
- restartable ECC tests (in this branch)
- server-side large packets (in development)

Resolution was to move the ECC tests after the newly added server large packet
ones.

Hanno Becker 0b44d5cc79 Zeroize sensitive data in aescrypt2 and crypt_and_hash examples
This commit replaces multiple `memset()` calls in the example
programs aes/aescrypt2.c and aes/crypt_and_hash.c by calls to
the reliable zeroization function `mbedtls_zeroize()`.

While not a security issue because the code is in the example
programs, it's bad practice and should be fixed.

Janos Follath a0b67c2f3e Bignum: Deprecate mbedtls_mpi_is_prime()
When using a primality testing function the tolerable error rate depends
on the scheme in question, the required security strength and wether it
is used for key generation or parameter validation. To support all use
cases we need more flexibility than what the old API provides.

Hanno Becker 095d9cf58e Fix ordering of free()ing of internal structures in ssl_server2
If `MBEDTLS_MEMORY_BUFFER_ALLOC_C` is configured and Mbed TLS'
custom buffer allocator is used for calloc() and free(), the
read buffer used by the server example application is allocated
from the buffer allocator, but freed after the buffer allocator
has been destroyed. If memory backtracing is enabled, this leaves
a memory leak in the backtracing structure allocated for the buffer,
as found by valgrind.

Fixes #2069.

Hanno Becker 30a95102b1 Fix memory leak and freeing without initialization in cert_write
* The variables `csr` and `issuer_crt` are initialized but not freed.
* The variable `entropy` is unconditionally freed in the cleanup section
  but there's a conditional jump to that section before its initialization.
  This cmmot Moves it to the other initializations happening before the
  first conditional jump to the cleanup section.

Fixes #1422.

Hanno Becker 101bcba26f UDP proxy: Allow more than one message to be delayed
Previously, the UDP proxy could only remember one delayed message
for future transmission; if two messages were delayed in succession,
without another one being normally forwarded in between,
the message that got delayed first would be dropped.

This commit enhances the UDP proxy to allow to delay an arbitrary
(compile-time fixed) number of messages in succession.

Manuel Pégourié-Gonnard 6e7aaca146 Move MTU setting to SSL context, not config
This setting belongs to the individual connection, not to a configuration
shared by many connections. (If a default value is desired, that can be handled
by the application code that calls mbedtls_ssl_set_mtu().)

There are at least two ways in which this matters:
- per-connection settings can be adjusted if MTU estimates become available
  during the lifetime of the connection
- it is at least conceivable that a server might recognize restricted clients
  based on range of IPs and immediately set a lower MTU for them. This is much
easier to do with a per-connection setting than by maintaining multiple
near-duplicated ssl_config objects that differ only by the MTU setting.

renegotiating.

Mohammad Azim Khan 9ebdcffef4 Fix Wformat-overflow warning in ssl_mail_client.c
sprintf( (char *) buf, "%s\r\n", base );
 Above code generates Wformat-overflow warning since both buf and base
are of same size. buf should be sizeof( base ) + characters added in
the format. In this case format 2 bytes for "\r\n".
