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()`.
For the sake of consistency, introduces the modifications have been made
to the test and utility examples as well. These, while less likely to be
used in the low level environments, won't suffer from such a change.
Don't use string literals that are longer than 4095 bytes, which is
the minimum that C99 compilers are required to support. Compilers are
extremely likely to support longer literals, but `gcc -std=c99 -pedantic`
complains.

Adapt ChangeLog
ssl_server2: Fail gracefully if no PEM-encoded CRTs are available
ssl_server2: Skip CA setup if `ca_path` or `ca_file` argument "none"
ssl_client2: Fail gracefully if no PEM-encoded CRTs are available
ssl_client2: Skip CA setup if `ca_path` or `ca_file` argument "none"
This allows to test PSK-based ciphersuites via ssl_server2 in builds
which have MBEDTLS_X509_CRT_PARSE_C enabled but both MBEDTLS_FS_IO and
MBEDTLS_CERTS_C disabled.
When MBEDTLS_MEMORY_BUFFER_ALLOC_C was defined, the sample ssl_server2.c was
using its own memory buffer for memory allocated by the library. The memory
used wasn't obvious, so this adds a macro for the memory buffer allocated to
make the allocated memory size more obvious and hence easier to configure.
Newer features in the library have increased the overall RAM usage of the
library, when all features are enabled. ssl_server2.c, with all features enabled
was running out of memory for the ssl-opt.sh test 'Authentication: client
max_int chain, server required'.
This commit increases the memory buffer allocation for ssl_server2.c to allow
the test to work with all features enabled.
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.
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.
This commit adds four tests to tests/ssl-opt.sh:
(1) & (2): Check behaviour of optional/required verification when the
trusted CA chain is empty.
(3) & (4): Check behaviour of optional/required verification when the
client receives a server certificate with an unsupported curve.
SHA-1 is now disabled by default in the X.509 layer. Explicitly enable
it in our tests for now. Updating all the test data to SHA-256 should
be done over time.
Adding the CA suppression list option to the 'ssl_server2' sample
program is a prerequisite for adding tests for this feature to the
integration test suite (ssl-opt.sh).
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.
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.
The library/net.c and its corresponding include/mbedtls/net.h file are
renamed to library/net_sockets.c and include/mbedtls/net_sockets.h
respectively. This is to avoid naming collisions in projects which also
have files with the common name 'net'.

This is not very useful for TLS as mbedtls_ssl_write() will automatically
fragment and return the length used, and the application should check for that
anyway, but this is useful for DTLS where mbedtls_ssl_write() returns an
error, and the application needs to be able to query the maximum length
instead of just guessing.
