We already have a specific component in all.sh for testing SSLv3, we don't
need to also test it in components that aren't specifically about it.
Previously config.py full enabled SSLv3, but it no longer does since it is
deprecated.
The splitting of this test into two versions depending on whether SHA-1 was
allowed by the server was a mistake in
5d2511c4d4 - the test has nothing to do with
SHA-1 in the first place, as the server doesn't request a certificate from
the client so it doesn't matter if the server accepts SHA-1 or not.
While the whole script makes (often implicit) assumptions about the version of
GnuTLS used, generally speaking it should work out of the box with the version
packaged on our reference testing platform, which is Ubuntu 16.04 so far.
With the update from Jan 8 2020 (3.4.10-4ubuntu1.6), the patches for rejecting
SHA-1 in certificate signatures were backported, so we should avoid presenting
SHA-1 signed certificates to a GnuTLS peer in ssl-opt.sh.
Because two buffers were aliased too early in the code, it was possible that
after an allocation failure, free() would be called twice for the same pointer.
When mbedtls_x509_crt_parse_path() checks each object in the supplied path, it only processes regular files. This change makes it also accept a symlink to a file. Fixes#3005.
This was observed to be a problem on Fedora/CentOS/RHEL systems, where the ca-bundle in the default location is actually a symlink.
ssl_decompress_buf() was operating on data from the ssl context, but called at
a point where this data is actually in the rec structure. Call it later so
that the data is back to the ssl structure.
Previously mocked non-blocking read/write was returning 0 when buffer was empty/full. That was causing ERR_SSL_CONN_EOF error in tests which was using these mocked callbacks. Beside that non-blocking read/write was returning ERR_SSL_WANT_READ/_WRITE depending on block pattern set by test design. Such behavior forced to redesign of these functions so that they could be used in other tests
This error occurs when free space in the buffer is in the middle (the buffer has come full circle) and function mbedtls_test_buffer_put is called. Then the arguments for memcpy are calculated incorrectly and program ends with segmentation fault
