Replace struct timeval with struct timespec as the main data type for
timestamps. This will allow the NTP code to work with timestamps in
nanosecond resolution.
Add offset option to the server/pool/peer directive. It specifies a
correction which will be applied to offsets measured with the NTP
source. It's particularly useful to compensate for a known asymmetry in
network delay or timestamping errors.
Add a new option (-c) to chronyc to enable printing of reports in a
column-separated values (CSV) format. IP addresses will not be resolved
to hostnames, time will be printed as number of seconds since the epoch
and values in seconds will not be converted to other units.
Add a new printf-like function to allow printing of all fields at once
and rework all commands which print a report to use it. Add functions
for printing of headers and information fields, and formatting of IP
addresses and reference IDs.
There was an incompatible change in the client access report. To avoid
bumping the protocol version drop support for the original request/reply
types and define new CLIENT_ACCESSES_BY_INDEX2 types as a newer version
of the command.
The clientlog record still uses 16-bit integers to count dropped
packets, but this will avoid an incompatible change in the command
reply if there will be a need to count more than 2^16 drops.
Require that at least one of the sources specified with this option is
selectable (i.e. recently reachable and not a falseticker) before
updating the clock. Together with the trust option this may be useful to
allow a trusted, but not very precise, reference clock or a trusted
authenticated NTP source to be safely combined with unauthenticated NTP
sources in order to improve the accuracy of the clock. They can be
selected and used for synchronization only if they agree with the
trusted and required source.
Assume time from a source that is specified with the trust option is
always true. It can't be rejected as falseticker in the source
selection if sources that are specified without this option don't agree
with it.
Instead of printing some large arbitrary values use dash in the LastRx
column of the sources output and the Last/Int columns in the clients
output when no sample or hit is recorded.
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.
- a feature test macro is needed to get msg_control in struct msghdr
- variables must not be named sun to avoid conflict with a macro
- res_init() needs -lresolv
- configure tests for IPv6 and getaddrinfo need -lsocket -lnsl
- pid_t is defined as long and needs to be cast for %d format
Follow the removal of the server authentication support and remove also
the client support. The -a and -f options are now silently ignored to
not break scripts. The authhash and password commands print a warning,
but they don't return an error.
Allow multiple hostnames/addresses separated by comma to be specified
with the -h option. Hostnames are resolved to up to 16 addresses. When
connecting to an address fails or no reply is received, try the next
address in the list.
Set the default value for the -h option to 127.0.0.1,::1.
If the specified hostname starts with /, consider it to be the path of
the chronyd Unix domain command socket. Create the client socket in the
same directory as the server socket (which is not accessible by others)
and change its permission to 0666 to allow chronyd running without root
privileges to send a reply. Remove the socket on exit.
Call connect() on the socket to set the remote address and switch from
sendto()/recvfrom() to send()/recv(). Setting the IP_RECVERR option no
longer seems to be necessary in order to get ECONNREFUSED errors.
