dst__openssl_toresult3() first calls toresult() and subsequently uses
ERR_get_error_line_data() in a loop. Given this, it is a mistake to use
ERR_get_error() in toresult() because it causes the retrieved error to
be removed from the OpenSSL error queue, thus preventing it from being
retrieved by the subsequent ERR_get_error_line_data() calls. Fix by
using ERR_peek_error() instead of ERR_get_error() in toresult().
When two or more absolute, two-label names are added to a completely
empty RBT, an extra, empty node for the root name will be created due to
node splitting. check_tree() expects that, but the extra node will not
be created when just one name is added to a completely empty RBT. This
problem could be handled inside check_tree(), but that would introduce
unnecessary complexity into it since adding a single name will result in
a different node count for a completely empty RBT (node count will be 1)
and an RBT containing only an empty node for the root name, created due
to prior node splitting (node count will be 2). Thus, first explicitly
create a node for the root name to prevent rare check_tree() failures
caused by a single name being added in the first iteration of the
insert/remove loop.
Each zone used in the "inline" system test contains a few dozen records.
Over a dozen of these zones are used in the test. Most records present
in these zones are not subsequently used in the test itself, but all of
them need to be signed by the named instances launched by the test,
which puts quite a bit of strain on lower-end machines, leading to
intermittent failures of the "inline" system test. Remove all redundant
records from the zones used in the "inline" system test in order to
stabilize it.
If "rndc signing -nsec3param ..." is ran for a zone which has not yet
been loaded or transferred (i.e. its "db" field is NULL), it will be
silently ignored by named despite rndc logging an "nsec3param request
queued" message, which is misleading. Prevent this by keeping a
per-zone queue of NSEC3PARAM change requests which arrive before a zone
is loaded or transferred and processing that queue once the raw version
of an inline-signed zone becomes available.
5006. [cleanup] Code preparing a delegation response was extracted from
query_delegation() and query_zone_delegation() into a
separate function in order to decrease code
duplication. [GL #431]
Changes introduced by the previous two commits make the parts of
query_delegation() and query_zone_delegation() which prepare a
delegation response functionally equivalent. Extract this code into a
separate function, query_prepare_delegation_response(), and then call
the latter from both query_delegation() and query_zone_delegation() in
order to reduce code duplication. Add a comment describing the purpose
of the extracted code. Fix coding style issues.
