md() already checks for md_info == NULL. Also, in the future it might also
return other errors (eg hardware errors if acceleration is used), so it make
more sense to check its return value than to check for NULL ourselves and then
assume no other error can occur.
Also, currently, md_info == NULL can never happen except if the MD and OID modules
get out of sync, or if the user messes with members of the x509_crt structure
directly.
This commit does not change the current behaviour, which is to treat MD errors
the same way as a bad signature or no trusted root.
The fact that self-signed end-entity certs can be explicitly trusted by
putting them in the CA list even if they don't have the CA bit was not
documented though it's intentional, and tested by "Certificate verification #73
(selfsigned trusted without CA bit)" in test_suite_x509parse.data
It is unclear to me whether the restriction that explicitly trusted end-entity
certs must be self-signed is a good one. However, it seems intentional as it is
tested in tests #42 and #43, so I'm not touching it for now.
With cmake, CFLAGS has to be set when invoking cmake, not make (which totally
ignores the value of CFLAGS when it runs and only keeps the one from cmake).
Also, in that case the flags were either redundant (-Werror etc) or wrong
(-std=c99 -pedantic) as some parts of the library will not build with
-pedantic (see the other -pedantic tests, which are correct, for what needs to
be disabled).
This is step 1 of a plan to get rid once and for all of missing depends_on in
the X509 test suite (step 2 will be RSA/ECDSA, and step 0 was curves.pl).
We have code to skip them but didn't have explicit tests ensuring they are
(the corresponding branch was never taken).
While at it, remove extra copy of the chain in server10*.crt, which was
duplicated for no reason.
This shows inconsistencies in how flags are handled when callback fails:
- sometimes the flags set by the callback are transmitted, sometimes not
- when the cert if not trusted, sometimes BADCERT_NOT_TRUSTED is set,
sometimes not
This adds coverage for 9 lines and 9 branches. Now all lines related to
callback failure are covered.
Now all checks related to profile are covered in:
- verify_with_profile()
- verify_child()
- verify_top()
(that's 10 lines that were previously not covered)
Leaving aside profile enforcement in CRLs for now, as the focus is on
preparing to refactor cert verification.
Previously flags was left to whatever value it had before. It's cleaner to
make sure it has a definite value, and all bits set looks like the safest way
for when it went very wrong.
The change in the truncated HMAC extension aligns Mbed TLS with the
standard, but breaks interoperability with previous versions. Indicate
this in the ChangeLog, as well as how to restore the old behavior.
Add mbedTLS.vcxproj to the VS2010 application template so that the next
time we auto-generate the application project files, the
LinkLibraryDependencies for mbedTLS.vcxproj are maintained.
Fixes#1347
In 2.7.0, we replaced a number of MD functions with deprecated inline
versions. This causes ABI compatibility issues, as the functions are no
longer guaranteed to be callable when built into a shared library.
Instead, deprecate the functions without also inlining them, to help
maintain ABI backwards compatibility.
Fix valid tag length values for mbedtls_ccm_encrypt_and_tag() function.
Add valid value ranges for mbedtls_ccm_auth_decrypt() parameters.
