nsd-4.1.27-bp151.3.3.1

- CVE-2020-28935.patch: Fix that symlink does not interfere
  with chown of pidfile (bsc#1179191, CVE-2020-28935)

- Update to upstream release 4.1.27:
  * FEATURES:
  - Deny ANY with only one RR in response, by default.  Patch from
    Daisuke Higashi.  The deny-any statement in nsd.conf sets ANY
    queries over UDP to be further moved to TCP as well.
    Also no additional section processig for type ANY, reducing
    the response size.
  - Fix #4215: on-the-fly change of TSIG keys with patch from Igor, adds
    nsd-control print_tsig, update_tsig, add_tsig, assoc_tsig
    and del_tsig.  These changes are gone after reload, edit the
    config file (or a file included from it) to make changes that
    last after restart.
  * BUG FIXES:
  - Fix #4213: disable-ipv6 and dnstap compile error.
  - Fix to reduce region_log_stats if condition, this removes a
    debug statement.
  - Fix for FreeBSD port with dnstap enabled.
  - Fix to remove unused code.
  - Fix #6: nsd-control-setup: Change validity time to a shorter
    period (<2038).
  - Fix unused definition in header remote.h.
  - Fix #4236: IPV4_MINIMAL_RESPONSE_SIZE=1480 is slightly too big.
  - Fix #4235: IP_PMTUDISC_OMIT on IPv4/UDP sockets.
  - Fixed radtree_insert memory leak.
  - Fixed access recycled variable.

- Update to upstream release 4.1.26:
  * FEATURES:
  - DNSTAP support for NSD, --enable-dnstap and then config in nsd.conf.
  - Support SO_REUSEPORT_LB in FreeBSD 12 with the reuseport: yes
    option in nsd.conf.
  - Added nsd-control changezone.  nsd-control changezone name pattern
    allows the change of a zone pattern option without downtime for
    the zone, in one operation.
  * BUG FIXES:
  - Fix #4194: Zone file parser derailed by non-FQDN names in RHS of
    DNSSEC RRs.
  - Fix #4202: nsd-control delzone incorrect exit code on error.
  - Tab style fix to use tab for 8 spaces, from Xiaobo Liu.
  - Fix #4205: enable-recvmmsg in mixed IPv4/IPv6 environment fails.
    This sets the msg_hdr.msg_namelen correctly after receipt.
  - Fix to not set GLOB_NOSORT so the nsd.conf include: files are
    sorted and in a predictable order.
  - Fix #3433: document that reconfig does not change per-zone stats.

- Update to upstream release 4.1.25:
  * FEATURES:
  - nsd-control prints neater errors for file failures.
  * BUG FIXES:
  - Fix that nsec3 precompile deletion happens before the RRs of
    the zone are deleted.
  - Fix printout of accepted remote control connection for unix sockets.
  - Fix use_systemd typo/leftover in remote.c.
  - Fix codingstyle in nsd-checkconf.c in patch from Sharp Liu.
  - append_trailing_slash has one implementation and is not repeated
    differently.
  - Fix coding style in nsd.c
  - Fix to combine the same error function into one, from Xiaobo Liu.
  - Fix initialisation in remote.c.
  - please clang analyzer and fix parse of IPSECKEY with bad gateway.
  - Fix nsd-checkconf fail on bad zone name.
  - Annotate exit functions with noreturn.
  - Remove unused if clause during server service startup.
  - Fix #4156: Fix systemd service manager state change notification
    When it is compiled, systemd readiness signalling is enabled.
    The option in nsd.conf is not used, it is ignored when read.

- Update to upstream release 4.1.24:
  - Features
  * #4102: control interface via local socket
  * configure --enable-systemd (needs pkg-config and libsystemd) can be
    used to then use-systemd: yes in nsd.conf and have readiness signalling
    with systemd.
  * RFC8162 support, for record type SMIMEA.
  - Bug Fixes
  * Patch to fix openwrt for mac os build darwin detection in configure.
  * Fix that first control-interface determines if TLS is used.
    Warn when IP address interfaces are used without TLS.
  * #4106: Fix that stats printed from nsd-control are recast from
    unsigned long to unsigned (remote.c).
  * Fix that type CAA (and URI) in the zone file can contain dots
    when not in quotes.
  * #4133: Fix that when IXFR contains a zone with broken NSEC3PARAM chain,
    NSD leniently attempts to find a working NSEC3PARAM.

- Update to upstream release 4.1.23:
  - Fix NSD time sensitive TSIG compare vulnerability.

- Update to upstream release 4.1.22:
  - Features:

    over UDP, and allows TCP queries like normal.
  * Use accept4 to speed up answer of TCP queries
  - Bug fixes:
  * Fix nsec3 hash of parent and child co-hosted nsec3 enabled zones.
  * Fix to use same condition for nsec3 hash allocation and free.
- Changes in version 4.1.21:
  - Features:
  * --enable-memclean cleans up memory for use with memory checkers,
    eg. valgrind.
  * refuse-any nsd.conf option that refuses queries of type ANY.
  * lower memory usage for tcp connections, so tcp-count can be
    higher.
  - Bug fixes:
  * Fix spelling error in xfr-inspect.
  * Fix buffer size warnings from compiler on filename lengths.

- Update to 4.1.20:
  + Fix memory leak in zone file read of unknown rr formatted RRs.
  + Fix memory leak when rehashing nsec3 after axfr or zonefile
    read, in the selectively allocated precompiled nsec3 hashes.

  + Drop SysV support from package (and hence usage of fillup)
  + Don't redefine %_rundir
  + Drop useless BuildRequires on systemd-devel

- Check group existence before creating it, for real.
- Stop deleting users from the system, it might remove a legitimate
  user that nsd unfortunately shared its name with.

- Own the config zones directory

  created names.

- update to 4.1.19 with the following bug fixes:
  * ignore fallthrough compiler warning in flex EOF rule.

    requires aligned access.
  * Fix spelling error in xfr-inspect.
  * Fix 3392: Fix regression in 4.1.18 for notify lists with ip4
    and ip6 targets.

    with 'make xfr-inspect' in the source dir.
  * retry timeout between sending notifies dropped from 15 to 3 sec.
  * NSD sends 16 notifies simultaneously.
  * configure --enable-packed reduces memory usage, at expense of unaligned
    reads. Saves about 17%.
