Correctly parse ntpq :config output on Python 3 and check return MACs.
Add AES and other algorithm support to ntpq and ntpdig, from OpenSSL.
Remove support for NetInfo. NetInfo was last supported in Mac OS X v10.4
The configure step now supports --disable-nts for running
on systems with older versions of OpenSSL.
The default restrictions now start with noquery and limited
to reduce the opportunities for being used for DDoS-ing.
The draft RFC for NTS has dropped support for TLSv1.2
We now need OpenSSL with TLSv1.3 support (version 1.1.1 or newer).
The config keyword +tlsciphers+ has been removed.
Additional filtering and sort options have been added to ntpq/mrulist
Details are in the man page.
Rate limiting has been cleaned up.
With "restrict limited", traffic is now limited to
an average of 1 packet per second with bursts of 20.
(needs doc and maybe config)
SIGHUP and hourly checks have been unified. Both now
check for a new log file
check for a new certificate file
check for a new leap file
SIGHUP also restarts all pending DNS and NTS probes.
NTS client now requires ALPN on TLSv1.3.
asciidoctor (1.5.8 or newer) is now supported and is the preferred AsciiDoc
processor. asciidoc is still supported, but the minimum supported version
has been raised from 8.6.0 to 8.6.8. asciidoc3 (3.0.2 or newer) is also
supported.
HTML docs are now built by default if an AsciiDoc processor is installed. If
you do not want HTML docs, configure with --disable-doc. (Note: Man pages
are controlled by a separate --disable-manpage.)
Analysis shows that CVE-2020-11868, affecting NTP Classic,
cannot affect us, as the peer mode involved has been removed.
== 2019-11-17: 1.1.8 ==
Fix bug in NTS-KE client so that NTP server names work.
Fix/tweak several NTS logging messages.
== 2019-09-02: 1.1.7 ==
The numeric literal argument of the 'time1' fudge option on a clock
can now have one or more letter suffixes that compensate for era
rollover in a GPS device. Each "g" adds the number of seconds in a
1024-week (10-bit) GPS era. Each "G" adds the number of seconds in a
8192-week (13-bit) GPS era.
The neoclock4x driver has been removed, due to the hardware and the
vendor having utterly vanished from the face of the earth.
The NTS ALPN negotiation sequence has been modified for improved
interoperability with other NTS implementations.
NTS key rotation now happens every 24 hours. It used to rotate
every hour to enable testing of recovery from stale cookies.
== 2019-07-10: 1.1.6 ==
Fixes to code quality checks.
Fixes to NTS server list.
Fix to bug #600.
== 2019-06-30: 1.1.5 ==
Add ALPN for the NTS server, as required by the NTP draft.
Revert some ntpq behavior.
== 2019-06-21: 1.1.4 ==
NTS is now implemented. See .../devel/nts.adoc
https://tools.ietf.org/html/draft-ietf-ntp-using-nts-for-ntp
We thank Cisco for sponsoring the NTS development.
Lots of fixes and cleanups to PPS, both implementation and documentation.
Pthread support is now required. --disable-dns-lookup is gone.
NIST lockclock mode is now a runtime option set by the (previously unused)
flag1 mode bit of the local-clock driver.
As always, lots of minor fixups and cleanups everywhere. See the git log.
