| Summary: File access library for scamper's binary dump format | |
Scamper is a program that is able to conduct Internet measurement tasks to large numbers of IPv4 and IPv6 addresses, in parallel, to fill a specified packets-per-second rate. Currently, it supports the well-known ping and traceroute techniques, as well as MDA traceroute, alias resolution, some parts of tbit, sting, and neighbour discovery. This package contains the library that provides access to the binary output files that scamper can produce in certain modes.

* update to version 20240920:
* 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
send signals to the privileged process, which it then forwards to
unprivileged process. the user who started scamper is otherwise not
able to send the unprivileged process signals, as that process
typically runs as user nobody.
* host: add -O nsid to signal queried server to include nsid OPT
record in response. parse any server-provided OPT records.
* udpprobe: record ifname replies were received on
* udpprobe: increase supported probe size from 1000 to 1400 bytes.
* factor out most repeated tls code patterns into utils_tls.c
* add functions to utils_tls.c to load key material from opened
file descriptors, to allow key material to be reloaded in
unprivileged process
* reload TLS key material on HUP signal
* do not negotiate use of TLS v1.1
* refactor privsep code to make it obvious which functions belong to
which process, and develop an obvious pattern in the code.
* make route socket interface work on NetBSD again
* tracelb: fix sport validation
* other minor code cleanups
* sc_minrtt:
* thread input stage, add batch import. by default, sc_minrtt
will import N files per batch, where N is the number of processors
online.
* add -b batchc parameter that allows for batch size to be adjusted
according to what is appropriate for the system
* set exit status to zero when import is successful
* add -v to emit version of scamper release the utility came from
* refactor code in places
* libscamperfile:
* bump version to account for added interfaces for udpprobe, host
objects.
* Python module:
* add nsid option to ScamperCtrl.do_dns method
* add ScamperUdpprobeReply.ifname attribute

(udpsize, edns_version, edns_do attributes)
* add context manager support to ScamperFile and ScamperCtrl, allowing
for Python with / as syntax
* sc_bdrmap:
* change -v vp-ases option to -V vp-ases
* add -v to emit version of scamper release the utility came from
* sc_attach, sc_hoiho, sc_remoted:
* add -v to emit version of scamper release the utility came from

- Remove upper bound on Cython, Cython 3 appears to be supported.
* Sat Aug 17 2024 Sebastian Wagner <[email protected]>
- update to version 20240716:
* 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.
* cleanup scamper_dlhdr.[ch], use scamper_dlhdr_t to scamper_probe_t
instead of its constituent parts.
* update tbit usage statement in scamper, and manual page, with
currently supported options
* python module:
* use join to assemble command strings for all ScamperCtrl.do_*()
for orders of magnitude faster command generation
* implement __richcmp__ for all classes where __eq__, __lt__, etc,
were previously defined individually
* if string passed to ScamperAddr is invalid, raise an exception
* implement ScamperCtrl.do_tbit method, ScamperTbit classes
* sc_minrtt:
* add sc_minrtt utility, which takes the output of sc_pinger to
produce a minimized RTT input file for sc_hoiho. to build, pass
- -enable-sc_minrtt as well as --with-pcre or --with-pcre2 to
configure, and have sqlite3 development headers and libraries in
build environment.
* tests:
* more ping and tbit command unit tests
* split out ARP reply parsing code into dl_parse_arp, add fuzzing cradle.
- update to version 20240725:
* scamper:
* add dynamic BPF filters for linux "any" packet interface, allowing
both -O dyn-filter and -O dl-any.
* avoid generating debugging statements that won't be emitted, saving
CPU in the usual scamper operating mode.
* process dltx timestamps when -N > 1 and tx timestamp is available
after the response has already arrived
* don't allow TCP traceroute and -N > 1 because packet matching
responses from the destination is challenging.
* use scamper_seteuid_[raise|lower] in scamper when built without
privsep, rather than use a repeated code pattern.
* configure:
* add --enable-scamper-ring to configure to make -O ring the default
* python module:
* take account of stop_hop when iterating through traceroute hops,
add ScamperTrace.stop_hop attribute.
* add ScamperTrace.addrs() convenience method, which returns unique
addresses observed in the path
* add ScamperHost.ans_ptrs() convenience method, which returns the
text from PTR records in a response
* update documentation:
https://www.caida.org/catalog/software/scamper/python/
* sc_analysis_dump:
* drop geolocation code from utility, which was not plumbed into
configure.
* tests:
* add check-ifdef.pl to check for obvious #ifdef bugs
- update to version 20240813:
* scamper:
* properly set icmp_id on ICMP probe signature in ping when -F 0.
* reduce code duplication in scamper_fd.c by replacing fd_udp() and
fd_tcp() with fd_tcpudp().
* process IPv6 TCP replies in dealias.
* simplify BPF logic, support unit testing of dl_filter_compile.
* fix 20240725 regression to actually call scamper_debug logic for
datalink packets.
* python module:
* raise exception if ScamperCtrl.do_*() is called on a ScamperInst
that has signalled EOF.
* add ScamperInst.is_eof() method.
* configure:
* check for tcp_timer.h in configure, use if found, to fix check
for tcp_var.h.
* sc_pinger, sc_minrtt:
* support batch probing with radargun primitive.
* update sc_pinger manual page with batch probing details.
* tests:
* silence benign clang static analysis warnings.
* add more ping command unit tests.
* add unit_dl_filter_compile to test bpf compiler.
* enhance check-ifdef.pl to find #define / #ifdef ordering issues,
make pass through code to adjust header ordering.
* Mon May 13 2024 Dominique Leuenberger <[email protected]>
- Fix dependency of libscamperfile-devel: require the new
libscamperfile9. The last updated bumped the so-version, which
results in a different package name.
- Drop all obsoletes of libscamperfile9: obsoleting old library
packages is explicitly not to be done according to the packaging
guidelines around shared libraries.
* Sun May 05 2024 Sebastian Wagner <[email protected]>
* update to version 20240503:
* 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.
* python library
* improve the usefulness of the ScamperInstError exceptions
* let all address parameters to do_() methods also be ScamperAddr
* support creation of ScamperAddr from bytes objects
* updates to support new functionality in udpprobe primitive
* support RR filters on all sections of a DNS response
* add tx, rx, and rtt attributes to DNS responses
* add qtype=txt, qclass=chaos, tcp DNS queries, and ScamperHostTxt
class.
* add helper method to get ns and txt records out of ans section
- - ans_nses() and ans_txts()
* add rx and ifname attributes to ScamperPingReply
* add ScamperDealiasProbe.is_from_target() method
* configure:
* remove obsolete AC_PROG_GCC_TRADITIONAL
* fix net/pfvar.h conditional
* sc_hoiho:
* fix crashes in IP and FNU stages so that router name regular
expression inferences work again.
* sc_wartscat:
* fix index into infiles array
* tests:
* add tests for string_byte2hex, and json escaping
* add unit tests for TXT records
* add fuzzing cradle for host_rr_list
* in fuzz_cmd cradle, ensure any error strings only contain printable
characters.
* Sat Mar 16 2024 Dirk Müller <[email protected]>
- update to 20240229:
* 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.
[#]# python module:
* generate module .c with Cython 0.29.37, to enable module to compile
with Python 3.11.
* link against libpython
* have all time parameters take either a timedelta or float/int. float/int
parameters are all seconds.
* add ScamperInstError exception which identifies the scamper instance
and includes the error string returned by the instance.
* reduce copying in methods that return bytes objects
* add str method for ScamperInst
- reenable python build
* Tue Feb 06 2024 Sebastian Wagner <[email protected]>
- Temporarily disable Python build because of incompatibility with Python 3.11
Reported upstream, will be fixed in next version.
* Mon Feb 05 2024 Sebastian Wagner <[email protected]>
- Update to version 20240122:
* scamper
* fix regression in 20240117 where trace -W 0 (probe as soon as
there's a response) was not accepted, despite being the default.
add unit test for this.
* for trace, improve probe and reply matching of UDP packets
* fix printing UDP responses to traceroute probes in scamper -O text output
* for trace section of scamper.1 man page, document -O const-payload,
and expand documentation for -O dl.
* python module:
* ship scamper release with a the C source code pre-generated for the
python module, so that the build process does not require a cython
installation. bootstrap.pl will build the C source code unless told
not to via --without-cython
* rename ScamperPing.reply_count to ScamperPing.stop_count, as the
reply_count attribute meant something different on a ScamperPing
object than what it means with ScamperDealiasProbe, etc
* sc_remoted:
* expand sc_remoted.1 manual page with information about validating
scamper client TLS certificates, and how to use -M monitor-name.
* Wed Jan 17 2024 Sebastian Wagner <[email protected]>
- update to version 20240117:
- scamper:
- fix crashes if a task is provided an apparent response, but the task
- has not yet sent a packet in ping, sting, tbit, trace, tracelb.
- find and fix memory leaks in measurement command parsing code via
- fuzzing.
- add udpprobe, http, dealias -m midarest, and dealias -m midardisc methods.
- udpprobe and http do not currently have json output methods.
- remove -d dport, -s sport, and -t ttl dealias parameters. these
- were only valid for mercator, and can be specified in a probedef instead.
- record size of responses for dealias probes.
- modify all commands to be able to take human-friendly wait parameters --
- e.g. trace -W 0.5s or trace -W 500ms instead of trace -W 50000.
- support transmitting raw packets on linux ppp interfaces
- add -b payload-size parameter to ping
- python interface:
- add python interface to most of scamper. building this module requires
- cython < 3.0. to build, use something like:
- PYTHON=/path/to/python CYTHON=/path/to/cython ./configure --with-python
- the documentation for this interface is available at
- https://www.caida.org/catalog/software/scamper/python/
- the ubuntu PPA provides python3-scamper, and the FreeBSD port should
- hopefully provide py-scamper shortly. these sources may be useful
- for getting the module packaged for other operating systems.

- update to version 20230605:
* HEADSUP: if you previously used -e pidfile to record the pid of a
running scamper process, there is a good chance that the pidfile is
owned by root. scamper now attempts to write this file using the uid
that started scamper, and will not be able to write it if scamper is
not started by root (it should not be, rather the scamper binary
should be setuid root). Please delete the existing pidfile, or change
its ownership, prior to restarting scamper, or scamper will not start.
* scamper:
* write a process ID that the user that started scamper can kill
in the pidfile when using privsep.
* when using privsep, exit the unprivileged process if the privileged
process exits (is killed)
* run as real uid from the start of scamper, for both privsep and
not-privsep.
* fix bug where attempting to open an unsupported datalink would
leave a freed scamper_fd_t in the fd_tree and fd_list, leading to
a crash.
* fix double free triggered when a user provides an invalid dealias
command.
* fix memory leak if the payload was specified twice to ping or trace
* rework pollfunc selection logic, use kqueue/epoll by default.
* remove _malloc_options = "AJ" as this only works on unsupported
versions of FreeBSD.
* add additional paramaters to attach command to allow the user
to override list and cycle parameters, documented in manual page.
* catch EAGAIN/EINTR from select/kqueue/epoll to allow gdb to attach
and detach without flagging errors.
* for DNS replies for host command, record reply flags and rcode.
* add support for SOA and NS queries in host.
* add a JSON output for host measurements.
* do not let scamper emit warts to a tty. check for isatty in
configure.
* only allow -O and -z to be specified multiple times in a trace command
* only allow -O to be specified multiple times in a ping command
* split command parsing logic out from task probing logic. add
fuzzing cradle for parsing logic for all measurement types, and
basic unit tests for dealias, ping, and trace parsing logic.
* autodetect output type by file extension if output type is not
explicitly specified on the command line.
* libscamperfile:
* remove all struct definitions from libscamperfile (e.g.
scamper_trace, scamper_ping, scamper_addr, etc). provide typedefs
for each (scamper_trace_t) and _get() functions that return the
field requested. This change will allow hopefully allow
libscamperfile's version to stabilize. all scamper utilities now
use these get functions.
* shift some functions that were previously implemented in
libscamperfile into the one place they were used, if they were only
used in (for example scamper / sc_analysis_dump / other scamper
utility). delete other functions that were not used anywhere in
the public scamper release.
* libscamperctrl:
* fix bug by ensuring line_off is always valid after the read.
* catch EAGAIN from select.
* add kqueue support.
* add scamper_attp_* routines to allow applications to specify
list and cycle parameters.
* for scamper_inst_do, take a parameter to keep with each task.
* add scamper_task_getparam function to get the parameter.
* add scamper_task_getcmd function to get the command associated with a task.
* use TYPE_FATAL instead of TYPE_ERR in application callback when
scamper_inst_read encounters a fatal error, only use TYPE_ERR when
scamper does not accept a command.
* sc_prefixprober:
* new driver to conduct measurements (ping, trace, tracelb) to an
address in each prefix.

- Drop libscamperfile1 provides from the lib subpckage:
libscamperfile.so.2 is not a drop-in replacement for anything
that linked libscamperfile.so.1, and as such the provides is

the upgrade path of a wrongly-packaged libscamperfile.so.2 in a
libscamperfile1 package.

that is not empty, so that sc_uptime can meet the probe interval.
* add the ability to expire addresses out of the database after they
have not been seen in traceroute for a while, and they do not
respond with an incrementing IPID value, with optional -E expiry
parameter.
* loading addresses into the state database is now a separate step (-a)

* add do-not-probe support
* replace import code that used a row for each sample with a blob that
stores multiple samples per blob.

* add cycle-start and cycle-stop json record implementations.
* fix traceroute json record: the hop transmit time value it reported
was junk.
* add support for sending json over the control socket. use
"attach format json" to get this mode; "attach" by itself still
returns uuencoded warts. Initial patch supplied by Young Hyun.
* fix possible memory leaks detected with static analysis.
* quality assurance on research paper cites in manual pages.
* spelling errors noticed by Iain R. Learmonth.
sc_ally:
* add feature to dump inferred aliases from the collected data.
sc_speedtrap:

- update to 20161204a
* More fixes to libscamperfile caught with fuzz testing. corrupt
warts files provided by Greg Ward of Dyn
* if targets or commands are specified in a file, and that file
ends after all probing of commands in that file has completed,
finish the source, allowing scamper to exit. this scenario is
most likely when stdin is the input file. Reported by Alex
Colvin of Dyn
* use select/poll/epoll/kqueue to look for read events on stdin files
* malloc enough memory for a prefix6_t in the prefixtree code. reported
by Sebastian Wagner via gcc7. only sc_bdrmap uses that code
* increase size of string buffers for some ping and trace fields for text
output to silence gcc7 warning.
* allow source IP address to be null when outputting a trace with json
* update sc_tbitblind.1 man page to show correct use of scamper's IPFW
firewall support, which changed in the 20161204 release
* fix unlikely unaligned access when computing checksums with IPv6
addresses
* Wed Jun 21 2017 [email protected]
- update to 20161204
* add remote control socket support to scamper. scamper can be
configured to connect to a remote controller at run time to
allow remote systems to control a scamper instance. the
remote controller is handled by the sc_remoted utility, and
is documented in the sc_remoted manual page (see below).
* fixes to libscamperfile caught with fuzz testing. corrupt
warts data files provided by Greg Ward of Dyn.
* add a PATRICIA trie implementation based off Sedgewick's
Algorithms in C++ book. this improves the performance
of scamper compared to holding addresses in splaytrees.
* improve speed of warts(5) code.
* improve speed of scamper_writebuf by allocating pagesize blocks
at a time.
* begin to document ping warts records in warts(5).

be built in as long as --without-debugfile is not used.
backported to 20141211g.
* silence compiler warnings from Microsoft Visual Studio.
backported to 20141211g.
