When a new master is selected, drop the old sync time stamp to prevent
calculating invalid delay in case delay_resp will be received before
first sync from the new master.

When the socket couldn't be opened (e.g. in clknetsim), the file
descriptor is invalid and shouldn't be used for sending.

Add 1 to port numbers printed in the log messages to make them
consistent with messages from port.c. The port number 0 is the UDS port,
which is last in the clock->port array.

This patch cleans up the BMC logic to allow assuming the GM role when no
other clocks are found in the network. By allowing the "best" to be NULL,
we can let the BMC to naturally pick the local clock as GM. As an added
bonus, this also get rid of the hacky check for a lost master.

This patch adds a new servo method to let the algorithm know about the
master clock's reported sync message interval. This information can be
used by the servo to adapt its synchronization parameters.

Management messages can cause a change in the clock quality. If this

This patch also replaces the hard coded logic for the UTC offset and the
time property flags with clock variables. This new clock state will be

This patch removes a redundant initialization of the kernel_leap clock

You'd probably expect the body of GET messages to be empty, but
interpretation #29 in
http://standards.ieee.org/findstds/interps/1588-2008.html implies
otherwise. With this change, ptp4l will respond to GETs containing
either an empty dataField or a dataField whose length matches the
managementId. If present, the contents of the dataField are ignored.

When a new master is selected, drop the old path delay and don't
calculate the offset until the delay is measured again with the new
master.

Reset the STA_UNSYNC flag and maxerror value with every frequency update

The clockid parameter to the function to get the system clock's maximum

When using software time stamping and a free running clock, the
statistics appear to be off by the TAI offset. This patch fixes the
issue by setting the internal UTC timescale flag in such cases.

Due to a bug in older kernels, frequency reading may silently fail and
return 0. Set the frequency to the read value to make sure the servo
has the actual frequency of the clock.

Add kernel_leap option for ptp4l and -x option for phc2sys to disable

Extend the clock_utc_correct function to handle leap seconds announced

New clock options should go into 'struct default_ds' so that we can avoid

Change the label of the frequency offset in the clock messages printed
by ptp4l and phc2sys from "adj" to "freq" to indicate it's a frequency

Also, modify clock_no_adjust() to print the frequency offset instead of
the ratio and use PRId64 instead of lld to print int64_t values.

Now that there are clock/port_management_set functions, the IDs that

If the port resets itself after detecting a fault, then the polling events
for that port are no longer valid. This patch fixes a latent bug that
would appear if a fault and another event were to happen simultaneously.

A timeout of 15 seconds is not always acceptable, make it configurable.
By popular consensus, instead of using a linear number of seconds, use
the 2^N format for the time interval, just like the other intervals in
the PTP data sets. In addition to numeric values, let the configuration
file support 'ASAP' to have the fault reset immediately.
[RC - moved the handling of special case tmo=0 and added a break out
of the fd event loop in case the fds have been closed.
- changed the linear seconds option to log second instead.
- changed the commit message to reflect the final version. ]
