Here is an update to net/rtorrent 0.16.24 and net/libtorrent 0.16.24
released on Sep 22, 2026.

changelog:
https://github.com/rakshasa/rtorrent/releases#release-v0.16.24

changelog has some security changes:
Fix one-byte overflow of the domain name buffer in udns dns_getdn
Fix heap overflow writing the question name of a compressed DNS reply
Fix use-after-free when p.multicall commands disconnect peers

portwise rtorrent does the following:
- regens test/Makefile.in patch to remove a new, third instance of -ldl

portwise libtorrent does the following:
- major bump due to removed symbols
- unbreaks tests by linking using static archive

Tests were already broken, due to undefined symbols when using libtool's
.la files. I tried putting manager.o into archive files. Alternatively,
I also tried patching test/Makefile.am with manager.{cc,h} and
introducing autoreconf / automake. Both alternatives let tests run but
they would double free during test cleanup.

ld: error: undefined symbol: torrent::manager
>>> referenced by runtime.cc:17 (runtime/runtime.cc:17)
>>>               runtime.o:(torrent::runtime::total_handshakes()) in archive /usr/obj/pobj/libtorrent-0.16.24/libtorrent-0.16.24/src/torrent/.libs/libtorrent_torrent.a
>>> referenced by file.cc:85 (data/file.cc:85)
>>>               file.o:(torrent::File::prepare(bool, int, int)) in archive /usr/obj/pobj/libtorrent-0.16.24/libtorrent-0.16.24/src/torrent/.libs/libtorrent_torrent.a
>>> referenced by file_list.cc:497 (data/file_list.cc:497)
>>>               file_list.

tj@ asked AI and proposed linking tests using the static archive
.libs/libtorrent.a. This makes sense since it has all of the objects
(plus a few more) found in torrent/.libs/libtorrent_torrent.a and
.libs/libtorrent_other.a

This unbreaks tests and downloading a debian torrent works.

OK to commit during ports slowdown?
