Tobias Brunner ba16a95454 asn1: Add OIDs for HMAC-based PRFs as defined in RFC 8018 2018-03-07 15:23:03 +01:00
Tobias Brunner 6b8749ab18 proposal: Compare algorithms of all transform types for equality 2018-03-05 12:25:19 +01:00
Tobias Brunner 76c7c951e1 proposal: Make sure to consider all transform types when selecting proposals
This way there will be a mismatch if one of the proposals contains
transform types not contained in the other (the fix list of transform
types used previously resulted in a match if unknown transform types
were contained in one of the proposals).  Merging the sets of types
makes comparing proposals with optional transform types easier (e.g.
DH for ESP with MODP_NONE).

Tobias Brunner ec1ebb2377 transform: Move internal identifiers out of private range
Avoid any conflicts if implementations use transform types in the
private range.
Also removed the unused UNKNOWN_TRANSFORM_TYPE identifier.

Tobias Brunner c1c63a400e appveyor: Allow events to trigger early in threading unit tests
The timed wait functions tested in the threading unit tests often but
randomly trigger a bit early on AppVeyor Windows containers.  We allow this
if it is not earlier than 5ms.

Tobias Brunner ac140220c4 proposal: Add modp6144 to the default proposal
We always had modp4096 and modp8192 included, not sure why this wasn't.

Tobias Brunner d9c9b7b832 proposal: Add method to move a given DH group to the front
This way a responder (like strongSwan) selecting a proposal first and
then checking if the KE payload matches sees the peer's preferred group
first.

Tobias Brunner c7263577b3 auth-cfg: Classify key strengths as multi value rules
If that's not the case only the last value added would be considered
not all the keys of a trust chain.

Tobias Brunner 432358cf49 revocation: Skip any zero bytes when comparing serials in CRLs
Depending on the plugins that eventually parse the certificate and CRL,
serials with MSB set (i.e. negative numbers that have a zero byte prefixed
when encoded as ASN.1 INTEGER) might have (x509 plugin) or not have
(openssl plugin) a zero byte prefix when returned by get_serial() or
enumerated from the CRL.  Strip them before doing the comparison or
revocation checking might fail if not both credentials are parsed by the
same plugin (which should be rare and only happen if parsing of either
cert or CRL fails with one of the plugins and there is a fallback to the
implementation provided by the other plugin).

Fixes #2509.

Reinhard Pfau a8e940ade2 eap: Reset errno before calling strtoul() to parse EAP type
Reset errno to 0 before calling strtoul() since it sets errno only on
error cases. So the following test fails even on correct conversions if
errno had a value != 0.

Fixes #2506.

Eyal Birger 2389168388 ipsec-types: Don't mask the mark value if it is one of the 'unique' values
Support for mark=%unique/%unique-dir is implemented by using designated
magic mark values.

Use of masks is orthogonal to the 'unique' feature, as it is useful to be
able to designate portions of the packet mark for other purposes, while
still using different marks for different connections.

When these magic values are masked, their magic meaning is lost.

Perform masking only on explicit mark values.

Closes strongswan/strongswan#87.

Tobias Brunner 2307bffe56 proposal: Move proposal_t from libcharon to libstrongswan
This allows us to use it without having to initialize libcharon, which
was required for the logging (we probably could have included debug.h
instead of daemon.h to workaround that but this seems more correct).

Thomas Egerer 9cc61baaf5 unit-tests: Rename targets for libstrongswan and kernel-netlink
libstrongswan and kernel-netlink are the only two components which do
not adhere to the naming scheme used for all other tests. If the tests
are run by an external application this imposes problems due to clashing
names.

Tobias Brunner 364395d2de Treat RSASSA-PSS keys like rsaEncryption RSA keys
In theory we should treat any parameters and the identifier itself as
restriction to only use the key to create signatures accordingly (e.g.
only use RSA with PSS padding or even use specific hash algorithms).
But that's currently tricky as we'd have to store and pass this information
along with our private keys (i.e. use PKCS#8 to store them and change the
builder calls to pass along the identifier and parameters). That would
require quite some work.

Tobias Brunner 3ce8b0556a gcrypt: Add support for RSA-PSS signatures
For salt lengths other than 20 this requires 0bd8137e68c2 ("cipher:
Add option to specify salt length for PSS verification."), which was
included in libgcrypt 1.7.0 (for Ubuntu requires 17.04).  As that makes
it pretty much useless for us (SHA-1 is a MUST NOT), we require that version
to even provide the feature.
