DNS_R_NCACHENXRRSET can be return when zones are in transition state
from being unsigned to signed and signed to unsigned. The validation
should be resumed and should result in a insecure answer.
(cherry picked from commit 718e597def)
- clone keynode->dsset rather than return a pointer so that thread
use is independent of each other.
- hold a reference to the dsset (keynode) so it can't be deleted
while in use.
- create a new keynode when removing DS records so that dangling
pointers to the deleted records will not occur.
- use a rwlock when accessing the rdatalist to prevent instabilities
when DS records are added.

Also disable the semantic patch as the code needs tweaks here and there because
some destroy functions might not destroy the object and return early if the
object is still in use.
if validator_start() is called with validator->event->message set to
NULL, we can't use message->rcode to decide which negative proofs are
needed, so we use the rdataset attributes instead to determine whether
the rdataset was cached as NXDOMAIN or NODATA.
as initial-key and static-key trust anchors will now be stored as a
DS rrset, code referencing keynodes storing DNSKEY trust anchors will
no longer be reached.
this function is used by dns_view_untrust() to handle revoked keys, so
it will still be needed after the keytable/validator refactoring is
complete, even though the keytable will be storing DS trust anchors
instead of keys. to simplify the way it's called, it now takes a DNSKEY
rdata struct instead of a DST key.
- val->keynode and val->seensig were set but never used.
- val->nearest, val->soaset, val->soaname, val->nsecset and val->nsec3set
were never used at all.
- pull out the code that checks whether a key was signed by a trust
anchor into a separate function, anchor_signed().
- pull out the code that looks up a DS while validating a zone key
into a separate function, get_dsset().
- check in create_validator() whether the sigrdataset is bound, so that
we can always pass in &val->fsigrdataset during an insecurity proof;
this will allow a reduction of code duplication.
- also simplified some calls: don't pass siginfo where val->siginfo
is sufficient, don't INSIST where returning false is sufficient.
- also added header comments to several local functions.
This commit add RUNTIME_CHECK() around all simple dns_name_copy() calls where
the third argument is NULL using the semantic patch from the previous commit.
isc_event_allocate() calls isc_mem_get() to allocate the event structure. As
isc_mem_get() cannot fail softly (e.g. it never returns NULL), the
isc_event_allocate() cannot return NULL, hence we remove the (ret == NULL)
handling blocks using the semantic patch from the previous commit.
Use them in structs for various rdata types where they are missing.
This doesn't change the structs since we are replacing explicit
uint8_t field types with aliases for uint8_t.
Use dns_dsdigest_t in library function arguments.
Improve dnssec-cds with these more specific types.
Replace dns_fixedname_init() calls followed by dns_fixedname_name()
calls with calls to dns_fixedname_initname() where it is possible
without affecting current behavior and/or performance.
This patch was mostly prepared using Coccinelle and the following
semantic patch:
@@
expression fixedname, name;
@@
- dns_fixedname_init(&fixedname);
...
- name = dns_fixedname_name(&fixedname);
+ name = dns_fixedname_initname(&fixedname);
The resulting set of changes was then manually reviewed to exclude false
positives and apply minor tweaks.
It is likely that more occurrences of this pattern can be refactored in
an identical way. This commit only takes care of the low-hanging fruit.
