commit 024842a38b9cff743de8101429f1c8e693070730
Author: Bryan Christianson <bryan@xxxxxxxxxxxxx>
Date: Mon Nov 30 10:13:03 2015 +1300
contrib: update chronylogrotate.sh script
1. Remove obsolete options when running chronyc
2. Add copyright/licence notice
3. Use logger utility to print/store error messages
commit 657929f8ec8fe7483c8e857d2aa3ba80ce8c4410
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Fri Nov 27 15:25:24 2015 +0100
cmdmon: update CLIENT_ACCESSES_BY_INDEX command
Add new fields from clientlog to the report and print them in chronyc.
Rework the code to skip empty records in the hash table. The reply no
longer has variable length, all client fields are filled even if some
are empty. Reply with RPY_NULL when the facility is disabled.
commit b506594c2d964ae462be6688f82b103195837821
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Nov 25 13:23:52 2015 +0100
clientlog: limit response rate
When the measured NTP or command request rate of a client exceeds
a threshold, reply only to a small fraction of the requests to reduce
the network traffic. Clients are allowed to send a burst of requests.
Try to detect broken clients which increase the request rate when not
getting replies and suppress the rate limiting for them.
Add ratelimit and cmdratelimit directives to configure the thresholds,
bursts and leak rates independently for NTP and command response rate
limiting. Both are disabled by default. Commands from localhost are
never limited.
commit 830135edea4c59c5b0a2f352bfd3309a1ca90893
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Wed Nov 25 09:57:12 2015 +0100
clientlog: measure request rates
Extend the record with estimates of the current client's NTP and command
request rates. Store them as 8-bit scaled log2 values to save memory.
commit 464cdbbb6e242c0daf2cdf3870439f035af4c00d
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Tue Nov 24 14:51:15 2015 +0100
clientlog: store records in hash table instead of tree
This simplifies the code and allows older records to be reused when no
more memory can be allocated for new addresses. Each slot of the hash
table has 16 records and there is no chaining between different slots.
Reused records may be newer than records in other slots, but the search
time remains constant.
commit 086e886d1e074e4a372d287f6508fa0a8c861c35
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Mon Nov 23 15:53:45 2015 +0100
clientlog: reduce amount of logged information
Don't log NTP peer access and auth/bad command access. Also, change
types for logging number of hits from long to uint32_t. This reduces the
size of the node and allows more clients to be monitored in the same
amount of memory.
commit f2b82c1e1d67ce3edec1b4da005c1ab46f27633e
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Tue Nov 24 12:30:54 2015 +0100
conf: don't allow disabling clientloglimit
Don't treat zero as a special value disabling clientloglimit. It's not
useful, the amount of available memory is never unlimited.
commit 801830df57ac866a69c0393dc58ae418788a2df9
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Fri Nov 27 11:03:16 2015 +0100
util: add macros for maximum, minimum and clamp
If MAX/MIN are defined in system headers, undefine them first.
commit 8b235297a596f3ddd6050994c845e2d7e22e72b2
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date: Mon Nov 23 15:24:33 2015 +0100
util: add function for IP address hashing
Move the hashing function from find_slot() in ntp_sources to make it
available to clientlog and improve the hashing a bit.
commit 59a3140621e723d631aaf99230db3f7c52b41192

cmdmon: tidy up declarations in read_from_cmd_socket()
commit 16bd56ae7e59651583f3d0e495f8eeb60462f7b2
Author: Bryan Christianson <bryan@xxxxxxxxxxxxx>
