https://mailman.caida.org/pipermail/scamper-announce/2023-August/000034.html

Merged ChangeLog

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:

• fix regression in multicall binary introduced in 20230605, so that scamper-ping, scamper-trace, etc, work again.
• for scamper -v (have scamper report its version), return 0 on exit from scamper process, rather than -1 (255).
• 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)
• fix handling of EPOLLHUP on client disconnection -- Linux-specific (scamper -U /path/to/socket)
• 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
• fix handling of disconnected instances
• 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:

• in sc_prefixprober, shuffle IPv6 addresses within a prefix, unless told not to.
• 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
• have sc_wartsdump print firsthop for trace records.

misc:

• build libcmdtest.a in tests to reduce duplication in Makefile.
