* 2.3.2 release
* Bug fixes / improvements since 2.3.1:
- systemd service file added and RPM spec updated
to handle systemd
- fixed segfault when shutting down NTP time service
- ptpengine:always_respect_utc_offset is now enabled
by default, to protect from clock jumps when GM
stops announcing currentUtcOffsetValid flag
- re-arranged order of InterfaceInfo fields to
fix memory alignment issues (SF bug #70)
- corrected logMessageInterval field values
for hybrid mode (SF bug #69)
- fixed NTPd check failures resulting from signals
interrupting select()
- increased statistics file line buffer size to prevent
truncation and merging of lines
- added Sequence ID to statistics log
- Solaris build fixes - linking lnsl and lsocket when
building without SNMP support
- critical: added minimum POSIX timer interval to prevent from
timers firing to quickly for the process to handle,
resulting in 100% CPU and endless signal queue
- improved processing of unicast destination, domain
and local preference lists
- CPU affinity setting moved to a separate function
- fixed incorrect PTP_UNICAST flag setting for multicast
- fixed missing management or signalling message acceptance
condition (clockid==clockid, portid=0xffff): ISPCS 2015 plugfest,
fourth missing: (clockid=0x(f), portid==portid)
- signaling.c: fixed order of grant processing for PTP messages
(ann,syn,fup,dresp,pdelayresp) instead of numeric loop,
to assist with interop where transmission request order
makes a difference to the master
- signaling.c: do not reset known clock ID when changing GMs,
to allow to keep accepting announce from other masters
- signaling.c: update unicast index when transport address
match only: fix for cache misses for non-best masters
- daemonconfig:c - reworked all config mapping macros
to functions, parseConfig now handless all operations:
parsing, quiet parsing, reload check, help - no hidden
values in dictionary anymore
- closed sf bug #64 - leaving mcast group with 0x0 address
- peer multicast group only joined when needed, not always
- logMessage now keeps hash of the last message body,
preventing from same message being repeated
- null checks getInterfaceInfo set of helper functions
in case if some data returned by getifaddrs() is null:
fixes segfaults on some exotic interface types
- signaling.c: use message type <-> smaller index number
conversion so grant table is 5-element, not 16-element:
significantly reduced memory footprint
- added dummy Makefile to src/dep to allow make commands
from that directory
- added buffer overflow protection for management
TLVs: protects against read past message length,
and against read past buffer space
* New features since 2.3.1:
- support for user variables in configuration:
- variables specified variables:name=val, and
used as @name@
- built-in variables: @pid@, @hostname@
- support for configuration templates:
- built-in
- template files
- unicast port number mask to assist with nodes
using different port IDs for negotiation
- option to accept any GM when unicast negotiation
is enabled
- UDP checksums disabled on Linux by default:
enables interop with TCs that don't correct checksums
- Added QNX support:
- clean build on QNX 6.5 out of the box
- adjfreq emulation using native ClockAdjust
- binding to CPU cores
- Experimental (but yield best results):
* interpolated getTime attached to IRQ0
* RX/TX timestamps in software on send or receive,
bypassing pcap or socket timestamping
- support for systems without getopt_long (like QNX)
- adjfreq-like behaviour on systems with adjtime only:
properly scaled adjtime() pulled into PI servo
(vastly improved sync on systems like OpenBSD and OSX),
support for drift file for those systems
- fixed preserving incorrect master address when
best master lowers priority (GM change as a result
of announce from current master, not foreign)
- PTP MIB enhanced with string values, counter support,
clearing counters and more, added some missing items
from previously supported items
- Alarm subsystem, many events implemented
- Alarm handlers: SNMP traps and log
- enhanced management message support: enable/disable port,
some missing values, PTPd now properly applies
configuration when receiving SET messages
- added simple SNMP poller script: snmptpq
- SNMP MIB now using PTPd's own Enterprise number
2013-06-10 Wojciech Owczarek <wojciech@owczarek.co.uk>

* slaves correctly negotiate message rates over supported
range of intervals until an acceptable interval is granted
+ support for unicast Peer Delay target - exotic use case
- greatly improved network robustness
- added support for slave-only builds (configure --slave-only):
allows building a binary incapable of running as master
- simple failover mechanism - ptpengine:backup_interface
- ptpengine:max_delay_max_rejected setting to unblock ptpd
rejecting all messages when max_delay set

and delay messages - min or median can be used in envifonments with high PDV
- added small step detection (millisecond level)
- added ptpengine:clock_update_timeout setting to reset slave
if no clock updates for a period of time
- when running slave-only in unicast mode, unicast address
does not have to be specified - ptpd will wait for a GM and latch onto it

- added options allowing to step the clock on startup
- improved sequence and re-ordering checks
- added support for "any domain" operation where ptpd will sync with
any available domain

from statistics file: allows sending statistics into syslog
- support for software transmit timestamping on Linux
- lookup tables used for matching Sync and FollowUp when
no transport information available
- added periodic status updates to log file (global:periodic_updates)
- status file will always display counters for common error events
if they are non-zero (includes denied unicast grants and ignored
Announce resulting from rejected UTC properties)

in the status file
- restored compatibility with 802.1AS
* Bug fixes / improvements since 2.3.0:
- added CentOS / RHEL 7.x support
- statistics code enabled by default - can be disabled
- NTPd failover code enabled by default - can be disabled
- Improved status file - more error conditions included,
message performance statistics included

other implementations: included is the old interval timer implementation,
and new (now default), POSIX timer implementation. This allows for
fully standards-compliant message rates. This can be disabled with
a configure flag

OpenBSD and LynxOS ()
- moving standard deviation algorithm fix improving the outlier
filters

PHC kernels
- fixed bug where ptpd would cause 100% CPU usage because of a
late TX timestamp
- fixed bug / feature request #22: prevent FMR from overwriting
best master
- improved servo stability detection: servo no longer reporting
stable when discarding most samples or heavily slewing
- ptpd will now join and leave multicast groups only when running
multicast or hybrid: allows running unicast and multicast
independently

and vice versa. In hybrid mode, only unicast Delay Request /
response is accepted; multicast management messages are always
accepted

- IEEE 802.3 Support
- Support for reading from the Berkeley Packet Filter, resulting in lower jitter
- Configuration file support, multiple previously unsupported options
- Rewritten command line parameter handling, new parameters
- Command line options to print default configuration, print lock file, check configuration and more,
- Full help (-H) for all configuration options,
- Configuration reload support with SIGHUP,
- Rewritten logging subsystem,
- Separate log file and statistics file, SIGHUP reprints the headers
- Support for mode and interface specific lock files
- Network interface checks before startup and during config reload
- Added ./configure --sigusr2=counters - will dump PTP engine countersto current log target when SIGUSR2 received
- Support for presets - groups of PTP protocol options defining ptpd behaviour
presets available: slaveonly, masteronly, masterslave
- Support for tick adjustment as well as frequency
maximum frequency offset is now configurable and can be above 512 ppm - tick is used above 512 ppm,
- Added a compatibility option to always honour the UTC offset announced by a GM when in slave state
- Added an announce receipt timeout "grace period" for slave state
slave can wait n times timeout without fully resetting
allows a seamless failover without resetting delay values etc.,
- Added support for DELAY_DISABLED delay mode - syntonisation only
- Initial support for informing the clock subsystem about the sync status
STA_UNSYNC is unset when adjusting the clock (allows syncing hardware RTC clocks with the system clock)
also maxerror and esterror are set,
- Support for RTC clock control on Linux
- Support for legacy command line switches from previous versions
- Configurable log level for normal logs, not only debug logs.
- Generic log file handler mechanism with a simple built-in logrotate implementation
for each log file container you can specify max size and max number of files
- Extensive support for realtime statistics
online long term statistics and moving statistics
mean and std dev.
Some new features included depend on statistics support, enabled with the --enable-statistics
configure switch. Statistics rely on double precision so may be disabled for simple embedded systems
- Outlier filters based on Peirce's criterion
blocks / filters spikes from delayMS and delaySM
- Generic PI controler model
- P and I components changed from attenuations to gains
- Double precision servo allows for tighter clock control

- Support for "panic mode"
if ptpd sees offset from master above 1 second, it will pause clock updates for a given amount of time
- NTPd integration and failover
ptpd can now connect to local ntpd using mode 7 packets (code derived from ntpdc)
and using authenticated requests can enable/disable ntpd clock control.
Enable with configure --enable-ntpdc
- Dump counters + clear counters using a SIGUSR2 handler to dump all counters to the log file
configure --enable-sigusr2=counters
- Support for ACLs for management and timing messages

- Support for non-Ethernet interfaces on Linux (Infiniband, GRE etc.)
- Support for offset / delay asymmetry correction
- Ptpd can now prefer or require GMs with valid UTC time
- Support for setting IP DSCP values
- Periodic IGMP joins also in master mode - improved robustness against network port failures
- Support for binding PTPd to a CPU core
- Control over tick rate on Linux, allowing faster clock slewing if needed
* Bug fixes:
- TTL no longer defaults to 64 in P2P mode - in P2P it's set to 1,
- Fixed an issue whereby observed drift would be reset to 0 if it
could not be read from the drift file (empty or nonexistent drift file),
now the kernel value is used if read from file fails.
- Support for updating utmp/wtmp when stepping the clock (FR #38)
- Mean Path Delay filtering now done in float (patch #49)
- Multiple other SourceForge bugs closed: Bugs closed:
#25, #34, #26, #42, #39, #33, #46, #45, #28,
#27, #48, #54, #47, #40, #37, #53, #50, #52, #59, #60
* Cleanups and other changes:
- Major startup.c cleanup, removed the parallel daemon checks,
in favour of better lock handling and the automatic lock file
name support,
- Some minor refactoring,
- Added a TimePropertiesDS structure and removed its fields
from PtpClock
- Improved log file format with full date and interface name,
removed the "===" indents
- Delay Request interval no longer mandatory in hybrid mode,
but a warning will be issued if it's not explicitly defined -
default of 0 is used,
- Removed the experimental status of hybrid mode,
- Manual stepping of the clock no longer just resets the observed
drift: resets it or restores it based on the drift handling setting,
and sets the time immediately before writing any logs - this allows
to re-sync and stabilise time almost instantly
- Up to date man pages written
