d0dfa1de9e adopt struct timespec
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.

32ac6ffa26 util: add UTI_GetRandomBytesUrandom()
This function always uses /dev/urandom, even if arc4random() is
available, and is intended for generating long-term keys.

saved, and real user UID/GID between system drivers.

8b235297a5 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.

116c697282 util: rework timestamp fuzzing
Use UTI_GetRandomBytes() instead of random() to generate random bits
below precision. Save the result in NTP_int64 in the network order and
allow precision in the full range from -32 to 32. With precision 32
the fuzzing now makes the timestamp completely random and can be used to
hide the time.

6199a89170 util: add function to generate random bytes
Add a function to fill a buffer with random bytes which uses a better
PRNG than random(). Use arc4random() if it's available on the system.
Fall back to reading from /dev/urandom, which should be available on
all currently supported systems.

30b6213910 util: set uid/gid of created directory even when zero
Call chown() in create_dir() even when the specified uid/gid is zero.
This is needed on BSD systems, where directories are created with gid
of the parent directory.

f1ed08abf0 conf: create directory for Unix domain command socket
Try to create the directory where will be the Unix domain command socket
bound to allow starting with empty /var/run. Check the permissions and
owner/group in case the directory already existed. It MUST NOT be
accessible by others as permissions on Unix domain sockets are ignored
on some systems (e.g. Solaris).

interval to which is mapped NTP time.

777303f130 Add support for different authentication hashes
Allow different hash functions to be used in the NTP and cmdmon
protocols. This breaks the cmdmon protocol compatibility. Extended key
file format is used to specify the hash functions for chronyd and new
authhash command is added to chronyc. MD5 is the default and the only
function included in the chrony source code, other functions will be
available from libraries.

a7892a1a15 Always send timevals in cmdmon protocol in 64-bit format
This is to avoid incompatibility between 64/32-bit client/server.
While at it, convert all time values in the protocol to timeval
to avoid Y2K38 problem.

8884034104 Equivalent to V1.19.99.1
This is a verbatim copy of the files at that stage of the repository that was
built from the CVS import.  It allows future development to see a bit of recent
history, but without carrying around the baggage going back to 1997.  If that
is really required, git grafts can be used.
