Conflict resolution:
* ChangeLog
* tests/data_files/Makefile: concurrent additions, order irrelevant
* tests/data_files/test-ca.opensslconf: concurrent additions, order irrelevant
* tests/scripts/all.sh: one comment change conflicted with a code
addition. In addition some of the additions in the
iotssl-1381-x509-verify-refactor-restricted branch need support for
keep-going mode, this will be added in a subsequent commit.
The relevant ASN.1 definitions for a PKCS#8 encoded Elliptic Curve key are:
PrivateKeyInfo ::= SEQUENCE {
version Version,
privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
privateKey PrivateKey,
attributes [0] IMPLICIT Attributes OPTIONAL
}
AlgorithmIdentifier ::= SEQUENCE {
algorithm OBJECT IDENTIFIER,
parameters ANY DEFINED BY algorithm OPTIONAL
}
ECParameters ::= CHOICE {
namedCurve OBJECT IDENTIFIER
-- implicitCurve NULL
-- specifiedCurve SpecifiedECDomain
}
ECPrivateKey ::= SEQUENCE {
version INTEGER { ecPrivkeyVer1(1) } (ecPrivkeyVer1),
privateKey OCTET STRING,
parameters [0] ECParameters {{ NamedCurve }} OPTIONAL,
publicKey [1] BIT STRING OPTIONAL
}
Because of the two optional fields, there are 4 possible variants that need to
be parsed: no optional fields, only parameters, only public key, and both
optional fields. Previously mbedTLS was unable to parse keys with "only
parameters". Also, only "only public key" was tested. There was a test for "no
optional fields", but it was labelled incorrectly as SEC.1 and not run because
of a great renaming mixup.
Change the script generate_errors.pl to call the grep function in Perl
instead of calling the external tool grep directly as this causes
problems when ANSI escape sequences are included in the grep output
string.
Only delete things that we expect to find, to avoid deleting other
things that people might have lying around in their build tree.
Explicitly skip .git to avoid e.g. accidentally matching a branch
name.
Use $ARMC5_BIN_DIR or --armc5-bin-dir to set the location of
armcc (version 5), for compatibility with later versions of Mbed TLS.
Ignore --armc6-bin-dir for the same reason, since in 2.1 we only test
with a single version of armcc and we expect version 5. Keep
defaulting to armcc in the $PATH for backward compatibility with the
2.1 branch.
Allow scripts to run all.sh --no-yotta unconditionally. --no-yotta
just happens to be a no-op in 2.1 since 2.1's all.sh doesn't do
anything with Yotta.
All options can now be overridden by a subsequent option, e.g.
"all.sh --foo --no-foo" is equivalent to "all.sh --no-foo". This
allows making wrapper scripts with default options and occasionally
overriding those options when running the wrapper script.
In mbedtls_ssl_derive_keys, don't call mbedtls_md_hmac_starts in
ciphersuites that don't use HMAC. This doesn't change the behavior of
the code, but avoids relying on an uncaught error when attempting to
start an HMAC operation that hadn't been initialized.
The 'critical' boolean can be set to false in two ways:
- by leaving it implicit (test data generated by openssl)
- by explicitly setting it to false (generated by hand)
This covers all lines added in the previous commit. Coverage was tested using:
make CFLAGS='--coverage -g3 -O0'
(cd tests && ./test_suite_x509parse)
make lcov
firefox Coverage/index.html # then visual check
Test data was generated by taking a copy of tests/data_files/crl-idp.pem,
encoding it as hex, and then manually changing the values of some bytes to
achieve the desired errors, using https://lapo.it/asn1js/ for help in locating
the desired bytes.
