* scamper:
* add initial implementation of RFC 4656 OWAMP. the implementation is
functional but incomplete, and all owamp interfaces (e.g., warts,
json, command line interface, python interface, and the
implementation itself) are subject to change.
* document current owamp command line interface in scamper man page.
* remove unused scamper_privsep_open_udp and scamper_privsep_open_tcp.
* sc_remoted:
* use unveil(2) and pledge(2) where present (OpenBSD) to restrict
the files sc_remoted has access to after initialization, and restrict
system calls available to sc_remoted.
* add optional-at-runtime chroot support to sc_remoted, to restrict
the files sc_remoted has access to after initalization on operating
systems without unveil(2), and add "security considerations" section
to sc_remoted man page on chroot support.
* refactor debug messages: most were errors that should have been
emitted to stderr even without using -O debug.
* add -O notimes option to remove timestamps, useful when the system
independently prefaces debug output with a timestamp.

debug messages.
* Python module:
* bindings for ScamperOwamp.
* drop GIL when calling clibscamperctrl.scamper_mux_add which can be
IO bound.

internally.
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=97
* rework most internal use of printerror/scamper_debug, tagging
measurement results with errmsg strings if an error occurs affecting
a measurement.
* emit errmsg strings in json and warts output. errmsg strings will
also be emitted to debugfile / stderr as before. these strings
are not emitted in text output of measurements.
* add error result code (stop reason) to dealias measurements.
* silently ignore unlikely PTR lookup error conditions for trace and
tracelb -- PTR lookups are not essential components of these
- measurements.
* fix memory leaks when encountering unlikely error conditions in
sting, tbit, tracelb, udpprobe.
- libscamperfile:
* add scamper_*_errmsg_get functions.
* let neighbourdisc src_mac and dst_ip be null when reading warts

- scamper:
* move items that require privilege (opening files, unlinking files,
opening raw sockets, datalink interfaces) into scamper_priv.c and
have each follow a consistent pattern. previously these were
distributed throughout many source code files.
* add build option that allows scamper to decide if it will do
privilege separation at run time.
the --enable-scamper-privsep=rootonly configure option enables this
behavior. if run with root privileges, scamper will do privilege
separation. if not run with root privileges, scamper will not.
--enable-scamper-privsep=yes (the default) does privilege separation
regardless of root privilege status.
note: the previous --disable-privsep configure option has become
--disable-scamper-privsep
* restructure the way that blocked tasks (tasks that share a probe
signature) are handled
* add -O mss=foo option to ping, which will include mss option to
TCP syn probe methods.
* ignore packets on the datalink interface associated with a probe
that has a timestamp after the datalink packet's timestamp.
* increase scamper -H holdtime limit from 10s to 60s.
- python module:
* add ScamperCtrl.outfile setter

- scamper:
* remove use of v?snprintf from more places to render strings faster
(especially ping and trace JSON)
* remove "outfile" commands from control socket
* remove most "source" commands from control socket, leaving only
"source list" for now.
* remove scamper's -O outcopy option
* add sentences documenting privilege separation to man page
* http: accept valid wildcard certs
* host: add edns-client-subnet and SVCB queries
* trace: include monitor-name in JSON output if known
* ping: separate scamper_ping_probe_t from scamper_ping_reply_t,
saving memory.
* ping: add stop reason and information about probes with no replies
to JSON output
* icmpexts: introduce a scamper_icmpexts_t structure that contains
scamper_icmpext_t structures, rather than use a linked list.
update trace and tracelb to use new storage form.
- sc_remoted:
* add mux support, enabling drivers to work with multiple remote
scamper instances over a single unix domain socket
* add metadata support, enabling sc_remoted to supply remote scamper
metadata to drivers

* scamper:
* handle many ports in BPF compiler better.
* remove cycles, autoreload features from file input sources.
* do not compile in support for select(2) by default (saving CPU and
memory in the default use).
* normalize kqueue(2) / epoll(2) code paths.
* use IP_RECVIF on platforms (FreeBSD) that don't have IP_PKTINFO.
* remove sig_tx_ip_src from task signature structure, nothing used it.
* add holdtime (-H) parameter back to scamper, will controls the
length of time that scamper will hold task signatures before
allowing a follow up measurement to use the same signature. 5
seconds by default, disable with zero (to save memory and CPU).
* fix compilation when platform has IPV6_PKTINFO but not
IPV6_RECVPKTINFO setsockopt (old platforms).
* replace calls to getaddrinfo AI_NUMERICHOST with calls to inet_pton
(fixes complilation on old MacOS, and is probably the faster
solution generally).
* increase pps-max (scamper -p) to 50,000.
* adjust timestamps using datalink timestamps when using
trace -N <squeries>.
* reduce memory use in storing traceroute state.
* remove per-measurement pktbufs, to save a tiny amount of memory.
* refactor BPF compiler to make it more obvious what is going on.
* refactor ping task signatures to make it more obvious what is going
on.
* refactor scamper's timeout calculation to make it more obvious what
is going on.
* move output of done tasks into its own function to make it more
obvious what is going on.

* scamper:
* add -O noring to disable use of ring buffer on Linux when
scamper is configured with --enable-scamper-ring
* udpprobe: add -S src parameter, update manual page with
previously supported but undocumented options
* sc_prefixprober:
* allow do-not-probe list to be embedded in the input set of
prefixes to probe, update manual page.
* add -v to emit version of scamper release the sc_prefixprober
utility came from
* Python module:
* add src parameter to ScamperCtrl.do_udpprobe
* update to version 20240916:
* scamper:
* with ping -F 0 and trace -s 0, choose a different TCP or UDP source
port if an otherwise available source port has been used in the past
5 seconds to the same destination IP and port.
* ping: add udp-sport probe method
* ping: refactor udp packet matching on datalink sockets
* allow -D when outputting to a file.
* use SO_TIMESTAMP on linux packet sockets, rather than call an ioctl,
to fix buggy linux timestamps when not using ring
* rework privsep code to be signal aware, and forward signals from
scamper's privileged process to scamper's unprivileged process via
the socketpair between the processes. i.e.,
scamper -D -U /path/to/scamper-unix-socket -e /path/to/scamper.pid
kill -HUP `cat /path/to/scamper.pid`
now works. TERM and INT also propagate from privileged to
unprivileged process. this allows the user that started scamper to
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=72
* scamper
* add -O dl-any option to scamper, which causes scamper to open a
cooked datalink interface bound to "any" on Linux. Note that
scamper's implementation of -O dl-any currently prevents
transmission of packets on the datalink socket, but this will
change in the future.
* add -O dyn-filter option to scamper, which causes scamper to
dynamically adjust the BPF filter that it configures on a datalink
socket according to TCP/UDP ports that scamper is using. this
option is only available on Linux, and BSD systems with BIOCSETFNR
(FreeBSD and MacOS). note that both -O dyn-filter and -O dl-any
cannot currently be used at the same time, but this will change in
the future.
* only raise SO_SNDBUF and SO_RCVBUF; some systems (e.g. Linux)
already have larger socket buffers than scamper's defaults.
* add -O sockrx to ping, to force ping to receive ICMP responses over
a regular socket, even when using -O dl (which still records datalink
transmit timestamps).
* speed up receiving on datalink sockets by avoiding unnecessary
memsets and removing unused fields, and adjust BSD, Linux, DLPI code
to follow similar code patterns.
* consider both directions for TCP packets on datalink sockets,
allowing datalink transmit timestamps to be recorded for non TCP-syn
packets.
* avoid processing duplicate copies of the same packet on Linux
loopback interface with datalink sockets.
* remove "observe" functionality from scamper control socket, as
signalled over a year ago. "outfile" and "source" will be removed
from the control socket in the future.
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=69
* scamper:
* improvements with -N squeries; let -Q send all probes when using -N.
add -H wait-probe-hop, which specifies the minimum delay between
probes with the same TTL. identify the hop that would have caused
traceroute to stop when not using -N so that a normal traceroute
path with one hop representing the destination or stopping hop in
the path is rendered. in the json output, put extra hops beyond
the stopping hop into a extra_hops array.
* make ring-nolocked the default when using -O ring.
* improvements with udpprobe: provide ability to send multiple copies
of the same payload, add json output, reuse available UDP sockets
where possible.
* consistently set and record the IPv4 tos and IPv6 tclass fields for
both ping and trace.
* fix warts.bz2 and warts.xz output, which could previously use all
available space on the file system.
* speed up rendering of byte arrays as hex in json output.
* fix obtaining IPv6 hoplimit on received packets on MacOS.
* record the name of the interface that received IPv4 and IPv6 ICMP
responses in ping.
* add TXT queries to host command; add chaos query class; add
DNS-over-TCP.
* fix use of ctype functions according to netbsd (cast all parameters
to unsigned char). make pass through use of ctype functions to do
ctype function calls last in most logical statements.
* cleanup scamper_file_warts.h so that only necessary struct
definitions are in that header.
* libscamperfile:
* add new functions, bump library version due to udpprobe changes.

* bugfix: correct SCAMPER_DL_IS_ICMP_TIME_REPLY macro so that scamper
does not ignore ICMP replies quoting TCP/UDP packets for 1/256
source port values.
* bugfixes for -O icmp-rxerr: handle EPOLLERR on linux, try using
IPV6_RECVHOPLIMIT before IPV6_HOPLIMIT for IPv6 udp probing.
* bugfix: fix possible assertions in dealias, trace, and tracelb code.
* ping: count UDP replies as from the target
* trace: correct datalink timestamp adjustments
* add more specific error messages when a scamper command is not
accepted, return them over control socket or terminal, as appropriate.
* scamper_fd_t: refactor fd_addr, fd_sport, fd_dl, fd_ifindex
* scamper_fd_t: decouple udp4raw/udp4dg from each other. use udp4dg
and udp6 sockets in udpprobe primitive, rather than have each
udpprobe task create its own socket.
* scamper_fd_t: add methods that return an available open socket for
probing a given destination without blocking if another task is
probing the same destination. use this with ping -F 0 and trace -s 0,
instead of generating random port values, so that scamper opens
the minimum number of file descriptors.
* ping and trace: have -O dl mean to capture transmit and receive
timestamps from a datalink interface. add -O raw option so that
IPv4 TCP probes can be transmitted over a raw socket, to allow transmitted
TCP packets to be observed on the datalink interface.
* add memory-mapped ring buffer support (PACKET_RX_RING) for receiving
packets on datalink sockets on Linux. enable at scamper runtime
with -O ring. contributed by Alistair King.

- update to version 20230614a
* configure:
* better tests for zlib, libbz2, and liblzma that check for both
libraries and headers.
* change --with-sc_uptime, --with-sc_hoiho, and --with-tests to be
--enable-sc_uptime, --enable-sc_hoiho, and --enable-tests
* disable maintainer mode, pass foreign to AM_INIT_AUTOMAKE
* scamper:
* remove reading regular files from poll/select/epoll/kqueue path,
which fixes reading regular input files (-f option to scamper) using
epoll or kqueue
* fix reading stdin as input (-f option to scamper) when using
epoll (catch EPOLLHUP)
* add DNS server to host signature, add host path for scamper_task_find
* rework scamper_osinfo to work with malformed release names (uname -r)
* dealias: do not crash on malformed prefixscan and bump commands
* dealias: fix memory leak of probedefs on malformed commands
* sting: fix memory leak of recorded packets
* remove tsps input method (-O tsps option to scamper)
* update manual page
* libscamperctrl:
* link against list.o and splaytree.o so that the library is self-contained
* fix memory leak when task is not accepted
* API improvements
* libscamperfile:
* fix memory leak when reading SOA/MX from warts file
* fix memory leak when reading PMTUD traceroute structures from warts file
* sting: fix memory leak of recorded packets
* sc_analysis_dump, sc_warts2pcap, sc_wartscat, sc_wartsfilter:
* link against list.o/utils.o so that these utilities are not reliant on
those symbols being exported from libscamperfile
* sc_prefixprober:
* allow compression type to be specified using -O
* free scamper_addr_t as each are removed from the list to probe
* sc_remoted:
* catch EPOLLHUP with epoll
* sc_warts2text:
* fix memory leaks
* sc_wartsdump:
* fix memory leaks
* link against utils.o so that sc_wartsdump is not reliant on those
symbols being exported from libscamperfile
