- scamper:
- allow multiple parallel measurements to the same destination,
- provided the measurements have probe signatures that scamper can
- distinguish.
- return the associated task ID with each DATA blob in control socket.
- this task ID matches the ID returned in an OK when scamper accepted
- the task.
- in ping, only compute delay statistics on responses from destination.
- in ping, allow timeout to be expressed in fractions of a second.
- libscamperfile:
- support reading gz-compressed warts files.
- libscamperctrl:
- add libscamperctrl, a library to interact with a collection of
- scamper instances.
- modify sc_ally, sc_filterpolicy, sc_prefixscan, sc_speedtrap, and
- sc_pinger to use this library.
- this library is likely to evolve. current behaviour is documented
- in libscamperctrl manual page.
- misc:
- improve sc_wartsfilter manual page with examples.
- add remote control socket support to sc_pinger.
- fix kqueue/epoll loop in sc_remoted.
- consistently use size_t throughout when counting number of items.
- build without warnings using -Wextra -Wno-unused-parameter.
- improvements through adding function attributes to printf-like
- functions.
- deorbit some unused functions from utils.c.

- scamper:
* gracefully handle situations where there is no
/etc/resolv.conf, or no nameserver lines in an /etc/resolv.conf
but a measurement or scamper-internal task wants to resolve a
name

- warts/json:
* in JSON output for ping, print the TCP/UDP src/dst ports or
ICMP id/seq used in individual probe packets,

in scamper's man page. output these hostnames into warts and
json outputs.
* bump libscamperfile version for the above changes.

JSON through an option now documented in scamper's man page.
* improvements to reading warts files via fuzzing.

geographic hints from router hostnames, documented in the
sc_hoiho man page

- update to version 20190916:
* scamper
* add a host implementation for looking up DNS records. it uses
the first nameserver it finds in /etc/resolv.conf by default.
* add an -O ptr option to tracelb.
* bugfix json output for tracelb.
* integrate patricia trie implementation into scamper hotspot
* use HAVE_SYSCTL macro to solve a compile issue on android
* include <linux/sockios.h> to get SIOCGSTAMP in Linux kernel > 5.2
* add -A option to ping code to set the ack number to use in tcp
probes (or sequence number in SYN packets). do not randomly
generate sequence and ack values for each TCP ping.
* rework options handling to allow for long long values.
* set the window size in TCP probes to 65535, instead of advertising a
zero receive window.
* update configure scripts around the use of --with-privsep-dir-owner
* sc_ally:
* when outputting alias sets, conduct a canonical sort to allow for
easy diffs
* update man page because sc_ally can take more than two addresses per
line
* sc_erosprober:
* new driver to periodically probe addresses and rotate output files.
* sc_hoiho:
* new utility for holistic orthography of Internet hostname
observations. this utility is only built if --with-sc_hoiho is
passed to configure. sc_hoiho requires pcre or pcre2, which can be
controlled by passing --with-pcre or --with-pcre2 to configure.
* sc_uptime:
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=19
* scamper:
* increase the size of a buffer in scamper's traceroute json
creation to reduce chance of truncation.

output.
* enforce a minimum firsthop value of 1 when reading a warts
traceroute object.
* sc_bdrmap:
* choose a static ICMP checksum value when using Paris traceroute
to reduce churn in observed topology in bdrmap output.
* add ability to pass list of ASes to -d traces to see
traceroutes towards specific ASes, useful for understanding
bdrmap inferences.
