Conrad Hoffmann [Thu, 23 Apr 2020 17:29:50 +0000 (19:29 +0200)] 
geoip: trigger CNAME chain resolution

Currently, when the geoip module returns a CNAME, knot will not resolve
it any further, even if it is within its authority. This forces clients
or recursors to issue an additional request to resolve the CNAME.

This commit enables the module to take advantage of knot's chain
resolution by updating the query data with the returned CNAME and
returning KNOT_IN_STATE_FOLLOW instead of KNOT_IN_STATE_HIT, which will
let knot to continue with the processing as it would for regular CNAME
results.

6 years agogeoip: stricter validation of CNAME usage
Conrad Hoffmann [Thu, 23 Apr 2020 07:59:14 +0000 (09:59 +0200)] 
geoip: stricter validation of CNAME usage

The geoip module does not validate the semantic validity of views, such
as that a CNAME cannot occur along with any other record. It will take
care to only return the right type in any given response, but this can
still lead to inconsistent results. Furthermore, one can supply two
CNAMEs in a view, and the module will write both of them into a
response.

This adds some input validation to tighten the rules of what the module
will accept as valid configuration, specifically that a CNAME cannot
occur along any other record in a view. This prevents ambiguities that
might otherwise arise in the query processing.

The additional storing of the domain name in case of a CNAME was chosen
in anticipation of using it for enabling CNAME chaing resolution,
implemented seperately.

xdp bugfix: avoid buffer leak opportunity

I had looked at this case before but I didn't see the problem;
fortunately Dan pointed me to it again.

When we bail out due to error, we can't just __release the indices
that we haven't processed; they would need to do at least
kxsk_dealloc_umem_frame()

We need that in kresd, as overwriting the program would detach
all the AF_XDP sockets and only the last kresd could receive.
It's not perfect, but I suppose we can bear that extraneous message.
