3938. [func] Added quotas to be used in recursive resolvers
that are under high query load for names in zones
whose authoritative servers are nonresponsive or
are experiencing a denial of service attack.
- "fetches-per-server" limits the number of
simultaneous queries that can be sent to any
single authoritative server. The configured
value is a starting point; it is automatically
adjusted downward if the server is partially or
completely non-responsive. The algorithm used to
adjust the quota can be configured via the
"fetch-quota-params" option.
- "fetches-per-zone" limits the number of
simultaneous queries that can be sent for names
within a single domain. (Note: Unlike
"fetches-per-server", this value is not
self-tuning.)
- New stats counters have been added to count
queries spilled due to these quotas.
These options are not available by default;
use "configure --enable-fetchlimit" (or
--enable-developer) to include them in the build.
See the ARM for details of these options. [RT #37125]
3839. [test] Use only posix-compatible shell in system tests.
[RT #35625]
(cherry picked from commit 60988462e5)
(cherry picked from commit 812cf443bb)
This incorporates the following changes, plus a new configure
option "--enable-rrl" to turn them on:
3575. [func] Changed the logging category for RRL events from
'queries' to 'query-errors'. [RT #33540]
3554. [bug] RRL failed to correctly rate-limit upward
referrals and failed to count dropped error
responses in the statistics. [RT #33225]
3545. [bug] RRL slip behavior was incorrect when set to 1.
[RT #33111]
3518. [bug] Increase the size of dns_rrl_key.s.rtype by one bit
so that all dns_rrl_rtype_t enum values fit regardless
of whether it is teated as signed or unsigned by
the compiler. [RT #32792]
3494. [func] DNS RRL: Blunt the impact of DNS reflection and
amplification attacks by rate-limiting substantially-
identical responses. To enable, use "configure
--enable-rrl". [RT #28130]
3528. [func] New "dnssec-coverage" command scans the timing
metadata for a set of DNSSEC keys and reports if a
lapse in signing coverage has been scheduled
inadvertently. (Note: This tool depends on python;
it will not be built or installed on systems that
do not have a python interpreter.) [RT #28098]
(cherry picked from commit 831f59eb43)
determine which DS records should be published
in the parent zone, or which DLV records should be
published in a DLV zone, and queries the DNS to
ensure that it exists. (Note: This tool depends
on python; it will not be built or installed on
systems that do not have a python interpreter.)
