| 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.
GPL-2.0-only

- 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 <sebix@sebix.at>
- 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 <sebix@sebix.at>
- 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 <sebix@sebix.at>
- 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.
- https://launchpad.net/~matthewluckie/+archive/ubuntu/scamper

* Tue Jun 13 2023 Sebastian Wagner <sebix@sebix.at>
- 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.
* sc_ally:
* use scamper_file_t outfiles, add ability to write gz/bz2/xz files.
* ask for cycle-start and cycle-stop records, write them out.

* Mon Apr 25 2022 Dominique Leuenberger <dimstar@opensuse.org>
- 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
invalid. The obsoletes is technically wrong, but is there to fix
the upgrade path of a wrongly-packaged libscamperfile.so.2 in a
libscamperfile1 package.
