The tests load certificate chains from files. The CA chains contain a
past or future certificate and an invalid certificate. The test then
checks that the flags set are MBEDTLS_X509_BADCERT_EXPIRED or
MBEDTLS_X509_BADCERT_FUTURE.
This change fixes a regression introduced by an earlier commit that
modified x509_crt_verify_top() to ensure that valid certificates
that are after past or future valid in the chain are processed. However
the change introduced a change in behaviour that caused the
verification flags MBEDTLS_X509_BADCERT_EXPIRED and
MBEDTLS_BADCERT_FUTURE to always be set whenever there is a failure in
the verification regardless of the cause.
The fix maintains both behaviours:
* Ensure that valid certificates after future and past are verified
* Ensure that the correct verification flags are set.
To do so, a temporary pointer to the first future or past valid
certificate is maintained while traversing the chain. If a truly valid
certificate is found then that one is used, otherwise if no valid
certificate is found and the end of the chain is reached, the program
reverts back to using the future or past valid certificate.
Fixes strict C99 builds in all.sh with glibc version >2.19 where platform support
wasn't being compiled in automatically.
Also fixes C99 syntax with armclang.
Pull Request #533 - Use MAKEFLAGS to pass args to make in all.sh
Modify the script at tests/scripts/all.sh to export the variable
MAKEFLAGS with -j if it was not set before. This should decrease the
total runtime of tests/scripts/all.sh by letting make run multiple jobs
in parallel. Also, add a check at the top of the script to cause a
failure if the environment is not Linux.w
Changes use of mklink in Windows test builds, to create junctions instead of
directory symbolic links. This removes the need for an elevated command prompt
when running cmake to create the Visual Studio project files.
Tighten up the test options in all.sh, test-ref-configs.pl and curves.pl
to ensure the builds are strict for all warnings, warnings are treated
as errors, and that wherever possible builds are strict to the C99
standard. (Note that builds that use the Unix sockets API cannot be).
Fixes many typos, and errors in comments.
* Clarifies many comments
* Grammar correction in config.pl help text
* Removed comment about MBEDTLS_X509_EXT_NS_CERT_TYPE.
* Comment typo fix (Dont => Don't)
* Comment typo fix (assure => ensure)
* Comment typo fix (byes => bytes)
* Added citation for quoted standard
* Comment typo fix (one complement => 1's complement)
The is some debate about whether to prefer "one's complement", "ones'
complement", or "1's complement". The more recent RFCs related to TLS
(RFC 6347, RFC 4347, etc) use " 1's complement", so I followed that
convention.
* Added missing ")" in comment
* Comment alignment
* Incorrect comment after #endif
The PKCS#1 standard says nothing about the relation between P and Q
but many libraries guarantee P>Q and mbed TLS did so too in earlier
versions.
This commit restores this behaviour.
