[nsd-users] NSD 4.3.0 released

[Wouter Wijngaards]

Hi,

NSD 4.3.0 is available:
https://nlnetlabs.nl/downloads/nsd/nsd-4.3.0.tar.gz
sha256 7a007d655d30f1edd001206839107e651966e1e519d53ba2c036491044111e97

This release adds cpu affinity.  By pinning a server process to a
specific cpu, having a separate network card also for that cpu, and
an interface address also for that server process, the throughput is
increased.  This increases performance of the nameserver.

Sparse TSIG signing support is removed, to comply with the latest tsig
standard update draft.

There is a feature to drop update queries, with opcode UPDATE,
with nsd.conf option drop-updates.


4.3.0

- Fix unused check of fd in parent_handle_reload_command.
- Attempt to fix signedness of nscount lookup in ixfr query_process.
- Fix identical branches for ssl_print of errors in remote.c.
- Fix type cast bounds, signedness of opt_rdlen in edns_parse_record.
- Fix to separate header and data lines in parse_zone_list_file.
- Fix to define max number of EDNS records we are willing to

- Fix size of string len and capacity type cast in udbradtree.
- Fix to protect rrcount in tsig_find_rr from overflow.
- Annotate radix_find_prefix_node not reachable trail code.
- Fix to protect rrcount in packet_find_notify_serial from overflow.
- Fix to close socket on error in create_tcp_accept_sock.
- Fix to log on failure to chmod for socket for remote control.
- Fix to remove unneeded if in open of socket for remote control.
