commit e488371b0111df6cbfd57ea97407706fec2044e6
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Aug 10 16:17:51 2016 +0200
sourcestats: report asymmetry in statistics log
commit 39f34eb67404b99d7a0f18390a0646bc90803abd
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Aug 10 15:51:51 2016 +0200
sourcestats: correct offsets with asymmetric network jitter
Estimate asymmetry of network jitter on the path to the source as a
slope of offset against network delay in multiple linear regression. If
the asymmetry is significant and its sign doesn't change frequently, the
measured offsets (which are used later to estimate the offset and
frequency of the clock) are corrected to correspond to the minimum
network delay. This can significantly improve the accuracy and stability
of the estimated offset and frequency.
commit 9d9d6c30cf0aaf7ccce213db70816957aa0379b3
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Aug 10 15:10:11 2016 +0200
sourcestats: add debug message for regression results
commit 27d59e54cc235a27457abb2627f9c579e52e01b4
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Tue Aug 9 15:28:32 2016 +0200
regress: add linear regression with two independent variables
commit 507a01ab17f95fa8c5b339d10dc3be2862aa90f8
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Mon Aug 8 15:51:51 2016 +0200
sourcestats: extend array holding peer delays
Keep the same number of peer delays as offsets. This will be needed when
peer delay is included in offset correction.
commit f7b8cd1a0933ff03c74aa8af1f4263cbcc577958
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Thu Aug 4 13:59:42 2016 +0200
regress: save arrays of constants in single-precision
No need to waste space on double precision. Also, declare them as const.
commit 8bc48af6307bac64a1b0655a4e51c1d3d1da085a
Author: Bryan Christianson <bryan@xxxxxxxxxxxxx>
Date: Thu Aug 4 20:08:07 2016 +1200
rename 'Mac OS X' to 'macOS'
From the the release of macOS Sierra (Version 10.12) the Macintosh
operating system is called 'macOS'
commit b0838280a985ab5fc1a781e1fea2e5f15a688545
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Aug 3 12:13:22 2016 +0200
ntp: reset tentative flag only when sample was accumulated
When selecting sources from a pool, ignore responses which didn't
produce a new sample. Sources with acceptable delay (as configured by
the maxdelay* options) should be prefered.
commit cea21adbbbaf38271e33cd8b412c55ee541c0c37
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Aug 3 12:07:43 2016 +0200
ntp: close client sockets sooner with unsynchronised sources
When a valid packet is received from an unsynchronised source (i.e. only
a test of leap, stratum or root distance failed), there is no point in
waiting for another packet or the RX timeout, and the client socket can
be immediately closed.
commit c619d555f0a39661a4d30388b490d38b83782623
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Tue Aug 2 13:44:57 2016 +0200
test: add 010-multrecv
commit e306199588cc7be6b548edf6f740d0f20c77cf35
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Tue Aug 2 12:17:15 2016 +0200
ntp: add support for recvmmsg()
This is used to read multiple packets with one system call. It should
work on Linux and NetBSD.
commit 895c15d677da08568d44c41b8f25192074fae0aa
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Tue Aug 2 12:15:56 2016 +0200
configure: include config.h in test code
commit d18f9ca75a59c93431d7ed5b4e5e2eaafa291a42
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Mon Aug 1 17:25:43 2016 +0200
ntp: rework receiving messages
Allocate buffers for received messages on heap instead of stack and
prepare the code for receiving multiple messages at the same time.
commit 82e76c39d9769e9bca02a122fccd6b3e85fce4d2
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
