Before the initial seeding, reseed_counter used to always be 0. Now, the
value depends on whether or not the user has explicitly set the amount
of data to get from the nonce (via e.g.
mbedtls_ctr_drbg_set_nonce_len()). Add comments to clarify the possible
values reseed_counter can have before the initial seeding.
The library style is to start with the includes corresponding to the
current module and then the rest in alphabetical order. Some modules
have several header files (eg. ssl_internal.h).
The recently added error.h includes did not respect this convention and
this commit restores it. In some cases this is not possible just by
moving the error.h declarations. This commit fixes the pre-existing
order in these instances too.
Now that the Error module has error codes as well and is processed by
the generate_errors script like any other module, we don't need to
include the header manually.
One of the error codes was already reserved, this commit just makes it
explicit. The other one is a new error code for initializing return
values in the library: `MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED` should
not be returned by the library. If it is returned, then it is surely a
bug in the library or somebody is tampering with the device.
This is useful to inspect what the script does manually, in particular
to check that expected values do get tested. --keep-c provides the
same information but in a way that's harder to access.
Filter out non-ASCII characters in automatically processed headers.
Do this in a way that minimizes the code change: keep manipulating
strings, but strip off non-ASCII characters when reading lines, which
should only remove characters in comments that we don't parse anyway.
In a unit test we want to avoid accessing the network. To test the
handshake in the unit test suite we need to implement a connection
between the server and the client. This socket implementation uses
two ring buffers to mock the transport layer.
