[PATCH 0/4] Crypto dependency fixes

[PATCH 0/4] Crypto dependency fixes

[Jussi Kukkonen]

This is a followup to (but does not strictly depend on) Nicholas'
"[PATCH v2] mesa: upgrade 10.6.3 -> 11.1.1" patch.

It adds packageconfig for xorg-xserver SHA1 implementation, and removes
some unnecessary crypto dependencies.

[PATCH 1/4] systemd: Don't depend on gcrypt unnecessarily

[Jussi Kukkonen]

Since upstream commit 79e8bde40 it's no longer necessary to depend
on gcrypt when --disable-gcrypt is used.

Looks good to me. this is the same implementation I used in the mesa
patch.. so we need to make sure that any review feedback is applied to
both before merging the too, should we get any review feedback.. but
in any case:

since its spans multiple recipes would it be better to control it with
a global knob instead of packageconfig.

Personally I'm not convinced that two recipes currently sharing a small
piece of configure code warrants a global configuration.

why not. this is probably a good thing. But I don't think we should
block the current patches as they are. If we want to add a
DISTRO_FEATURES the patches we did in mesa and xserver are needed
anyways. Once every possible 'crypto' config are available as
PACKAGECONFIG we simply need to add one line to pick the one we need
based on DISTRO_FEATURE content. So I think we should merge them, and
discuss/plan how to add crypto as a distro policy.

Thats ok. However, if there is a time to do something to consolidate crypto backend
policy then such instances are the right one. I know you have a solution for your problem.

I'm not sure it makes sense in -this- case..  but I've more then once thought
that it would be nice for a global distro "this is the preferred crypto engine"
setting.

That way you could do things like default to openssl, libgcrypt, libnss, etc..
whatever is appropriate for the system you are building.  It wouldn't promise
that everything would just use that crypto backend, but things that could -- should.

(This is certainly a more extensive patch then what's being discussed here..)

I was wondering if something like this was possible as well: that's how I
got into reviewing the reverse dependencies of openssl & gnutls.

There are some cases that might make this effort not worth the trouble:
SHA1 is easy and switching implementations is something upstream projects
want to support but with e.g. TLS it is not always so: An example is
glib-networking with only gnutls for TLS support*.

Jussi


*) There's a "wip/openssl" branch of glib-networking so this might get
fixed in future releases .

This is why I suggest it isn't an all or nothing, but instead a hint for the
recipes that support multiple crypto backends.

In one of my products, we use OpenSSL (w/ the FIPS module) as the primary crypto
engine for the system.  We had to configure a number of recipes/packageconfig
settings to use OpenSSL as the primary crypto engine.

It would have been much easier to just set a single distribution setting and
then update the recipes to pay attention to the single setting.
