BIND 9.20.8
|
||||
-----------
|
||||
|
||||
New Features
|
||||
~~~~~~~~~~~~
|
||||
|
||||
- Add support for EDE 20 (Not Authoritative) ``f8a293aa11``
|
||||
|
||||
Support was added for EDE codes 20 (Not Authoritative) when client
|
||||
requests recursion (RD) but the server has recursion disabled.
|
||||
|
||||
RFC 8914 mention EDE 20 should also be returned if the client doesn't
|
||||
have the RD bit set (and recursion is needed) but it doesn't apply for
|
||||
BIND as BIND would try to resolve from the "deepest" referral in
|
||||
AUTHORITY section. For example, if the client asks for "www.isc.org/A"
|
||||
but the server only knows the root domain, it will return NOERROR but
|
||||
no answer for "www.isc.og/A", just the list of other servers to ask.
|
||||
:gl:`#1836` :gl:`!10243`
|
||||
|
||||
- Add support for EDE 7 and EDE 8. ``27442c3104``
|
||||
|
||||
Support was added for EDE codes 7 (Signature Expired) and 8 (Signature
|
||||
Not Yet Valid) which might occur during DNSSEC validation. :gl:`#2715`
|
||||
:gl:`!10242`
|
||||
|
||||
- Dig can now display the received BADVERS message during negotiation.
|
||||
``a763080a87``
|
||||
|
||||
Dig +showbadvers now displays the received BADVERS message and
|
||||
continues the EDNS version negotiation. Previously to see the BADVERS
|
||||
message +noednsneg had to be specified which terminated the EDNS
|
||||
negotiation. Additionally the specified EDNS value (+edns=value) is
|
||||
now used when making all the initial queries with +trace. i.e EDNS
|
||||
version negotiation will be performed with each server when performing
|
||||
the trace. :gl:`#5234` :gl:`!10247`
|
||||
|
||||
- Add an rndc command to reset some statistics counters. ``7c4603fc4a``
|
||||
|
||||
The new ``reset-stats`` command for ``rndc`` allows some statistics
|
||||
counters to be reset during runtime. At the moment only two
|
||||
"high-water" counters are supported, so the ability to reset them
|
||||
after the initial peaks during the server's "warm-up" phase may be
|
||||
useful for some operators. :gl:`#5251` :gl:`!10335`
|
||||
|
||||
- Implement -T cookiealwaysvalid. ``1da738ffbb``
|
||||
|
||||
When `-T cookiealwaysvalid` is passed to `named`, DNS cookie checks
|
||||
for the incoming queries always pass, given they are structurally
|
||||
correct. :gl:`!10264`
|
||||
|
||||
Removed Features
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
- Remove dns_qpmulti_lockedread declaration. ``42ab4fce4a``
|
||||
|
||||
This function was removed in 6217e434b57bd5d60ed69f792ae9a1a65a008f57
|
||||
but not from the header file. :gl:`!10314`
|
||||
|
||||
Feature Changes
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
- Carefully check if the server name used for SNI is a hostname.
|
||||
``92eb6416e5``
|
||||
|
||||
Previously the code would not check if the string intended to be used
|
||||
for SNI is a hostname.
|
||||
|
||||

|
||||
|
||||
Bug Fixes
|
||||
~~~~~~~~~
|
||||
|
||||
- Restore NSEC3 closest encloser lookup improvements. ``ab6fb7b8f2``
|
||||
|
||||
A performance improvement for finding the closest encloser when
|
||||
generating authoritative responses from NSEC3 zones was previously
|
||||
reverted after a bug was found that could trigger an assertion
|
||||
failure. ( :gl:`#4460`, #4950, and #5108 for details.) The bug has
|
||||
now been fixed, and the performance improvement has been restored.
|
||||
:gl:`#5204` :gl:`!10034`
|
||||
|
||||
- Add missing locks when returning addresses. ``2c7594709c``
|
||||
|
||||
Add missing locks in dns_zone_getxfrsource4 et al. Addresses CID
|
||||
468706, 468708, 468741, 468742, 468785, and 468778.
|
||||
|
||||
Cleanup dns_zone_setxfrsource4 et al to now return void.
|
||||
|
||||
Remove double copies with dns_zone_getprimaryaddr and
|
||||
dns_zone_getsourceaddr. :gl:`#4933` :gl:`!10259`
|
||||
|
||||
- Stop caching lack of EDNS support. ``96bb3a1952``
|
||||
|
||||
`named` could falsely learn that a server doesn't support EDNS when a
|
||||
spoofed response was received; that subsequently prevented DNSSEC
|
||||
lookups from being made. This has been fixed. :gl:`#3949` :gl:`#5066`
|
||||
|
||||
- Step() could ignore rollbacks. ``2334b7a371``
|
||||
|
||||
The `step()` function (used for stepping to the prececessor or
|
||||
successor of a database node) could overlook a node if there was an
|
||||
rdataset that was marked IGNORE because it had been rolled back,
|
||||
covering an active rdataset under it. :gl:`#5170` :gl:`!10257`
|
||||
|
||||
- Fix resolver statistics counters for timed out responses.
|
||||
``1d8334a62a``
|
||||
|
||||
When query responses timed out, the resolver could incorrectly
|
||||
increase the regular responses counters, even if no response was
|
||||
received. This has been fixed. :gl:`#5193` :gl:`!10287`
|
||||
|
||||
- Validating ADB fetches could cause a crash in import_rdataset()
|
||||
``b0c6af6ad7``
|
||||
|
||||
Previously, in some cases, the resolver could return rdatasets of type
|
||||
CNAME or DNAME without the result code being set to `DNS_R_CNAME` or
|
||||
`DNS_R_DNAME`. This could trigger an assertion failure in the ADB. The
|
||||
resolver error has been fixed. :gl:`#5201` :gl:`!10329`
|
||||
|
||||
- Nested DNS validation could cause assertion failure. ``6bf4390f25``
|
||||
|
||||
When multiple nested DNS validations were destroyed out of order, the
|
||||
EDE context could be freed before all EDE codes were copied, which
|
||||
could cause an assertion failure. This has been fixed. :gl:`#5213`
|
||||
:gl:`!10366`
|
||||
|
||||
- [9.20] Wait for memory reclamation to finish in named-checkconf.
|
||||
``9986dad2dc``
|
||||
|
||||
Previously, when named-checkzone loaded the zone to the QP database,
|
||||
the delayed memory reclamation could cause an assertion check on exit.
|
||||
This has been fixed. :gl:`#5220` :gl:`!10307`
|
||||
|
||||
- Ensure max-clients-per-query is at least clients-per-query.
|
||||
``8f78219cc1``
|
||||
|
||||
If the `max-clients-per-query` option is set to a lower value than
|
||||
`clients-per-query`, the value is adjusted to match
|
||||
`clients-per-query`. :gl:`#5224` :gl:`!10244`
|
||||
|
||||
- Fix handling of revoked keys. ``a347273b9c``
|
||||
|
||||
When a key is revoked, its key ID changes due to the inclusion of the
|
||||
"revoked" flag. A collision between this changed key ID and an
|
||||
unrelated public-only key could cause a crash in `dnssec-signzone`.
|
||||
:gl:`#5231` :gl:`!10256`
|
||||
|
||||
- Fix adbname reference. ``7ebcc54d3b``
|
||||
|
||||
Call `dns_adbname_ref` before calling `dns_resolver_createfetch` to
|
||||
ensure `adbname->name` remains stable for the life of the fetch.
|
||||
:gl:`#5239` :gl:`!10303`
|
||||
|
||||
- Fix write after free in validator code. ``5de1b3ba3c``
|
||||
|
||||
Raw integer pointers were being used for the validator's nvalidations
|
||||
and nfails values but the memory holding them could be freed before
|
||||
they ceased to be used. Use reference counted counters instead.
|
||||
:gl:`#5239` :gl:`!10300`
|
||||
|
||||
- Don't enforce NOAUTH/NOCONF flags in DNSKEYs. ``5d126d8081``
|
||||
|
||||
All DNSKEY keys are able to authenticate. The `DNS_KEYTYPE_NOAUTH`
|
||||
(and `DNS_KEYTYPE_NOCONF`) flags were defined for the KEY rdata type,
|
||||
and are not applicable to DNSKEY. Previously, however, because the
|
||||
DNSKEY implementation was built on top of KEY, the `_NOAUTH` flag
|
||||
prevented authentication in DNSKEYs as well. This has been corrected.
|
||||
:gl:`#5240` :gl:`!10315`
|
||||
|
||||
- Fix several small DNSSEC timing issues. ``3a78a4c288``
|
||||
|
||||
The following small issues related to `dnssec-policy` have been fixed:
|
||||
- In some cases the key manager inside BIND 9 could run every hour,
|
||||
while it could have run less often. - While `CDS` and `CDNSKEY`
|
||||
records will be removed correctly from the zone when the corresponding
|
||||
`DS` record needs to be updated, the expected timing metadata when
|
||||
this will happen was never set. - There were a couple of cases where
|
||||
the safety intervals are added inappropriately, delaying key rollovers
|
||||
longer than necessary. - If you have identical `keys` in your
|
||||
`dnssec-policy`, they may be retired inappropriately. Note that having
|
||||
keys with identical properties is discouraged in all cases.
|
||||
:gl:`#5242` :gl:`!10301`
|
||||
|
||||
- Copy __FILE__ when allocating memory. ``59635e33d0``
|
||||
|
||||
When allocating memory under -m trace|record, the __FILE__ pointer is
|
||||
stored, so it can be printed out later in order to figure out in which
|
||||
file an allocation leaked. (among others, like the line number).
|
||||
|
||||
However named crashes when called with -m record and using a plugin
|
||||
leaking memory. The reason is that plugins are unloaded earlier than
|
||||
when the leaked allocations are dumped (obviously, as it's done as
|
||||
late as possible). In such circumstances, `__FILE__` is dangling
|
||||
because the dynamically loaded library (the plugin) is not in memory
|
||||
anymore.
|
||||
|
||||
Fix the crash by systematically copying the `__FILE__` string instead
|
||||
of copying the pointer. Of course, this make each allocation to
|
||||
consume a bit more memory (and longer, as it needs to calculate the
|
||||
length of `__FILE__`) but this occurs only under -m trace|record
|
||||
debugging flags. :gl:`!10336`
|
||||
|
||||
- Fix invalid cache-line padding for qpcache buckets. ``4297ae4795``
|
||||
|
||||
The isc_queue_t was missing in the calculation of the required padding
|
||||
size inside the qpcache bucket structure. :gl:`!10317`
