W ga\u0142\u0119zi net-next, w kt\u00f3rej gromadzone s\u0105 zmiany do przysz\u0142ego wydania j\u0105dra Linux 6.16, wprowadzono zmian\u0119, kt\u00f3ra usuwa wsparcie dla protoko\u0142u sieciowego DCCP (Datagram Congestion Control Protocol). Wsparcie dla modu\u0142\u00f3w netfilter do filtrowania pakiet\u00f3w DCCP pozostaje. Protok\u00f3\u0142 DCCP zosta\u0142 znormalizowany i zaakceptowany w j\u0105dra w 2006 roku. Zak\u0142adano, \u017ce DCCP zwi\u0119kszy efektywno\u015b\u0107 strumieniowania i telefonii internetowej w przeci\u0105\u017conych sieciach, jednak w praktyce protok\u00f3\u0142 okaza\u0142 si\u0119 zb\u0119dny i nie zdoby\u0142 popularno\u015bci. <\/p>\n

Kod DCCP w j\u0105drze pozostaje bez wsparcia ju\u017c od pi\u0119ciu lat, a zmiany w ostatnich latach ogranicza\u0142y si\u0119 do poprawek wynikaj\u0105cych z refaktoryzacji API j\u0105dra. Kilka lat temu w ramach projektu Multipath DCCP podj\u0119to pr\u00f3b\u0119 rozwoju protoko\u0142u DCCP w j\u0105drze, ale cz\u0119\u015b\u0107 kodu tego projektu pozostaje w\u0142asno\u015bciowa. Tw\u00f3rca Multipath DCCP planowa\u0142 otworzy\u0107 kod w\u0142asno\u015bciowych cz\u0119\u015bci, przekaza\u0107 zgromadzone zmiany do g\u0142\u00f3wnego j\u0105dra i wzi\u0105\u0107 na siebie obowi\u0105zki maintainera DCCP w j\u0105drze Linux, ale od kilku lat nie nawi\u0105za\u0142 kontaktu. <\/p>\n

Usuni\u0119cie DCCP z j\u0105dra Linux usunie przeszkody utrudniaj\u0105ce przebudow\u0119 struktury danych inet_connection_sock w celu zwi\u0119kszenia efektywno\u015bci dzia\u0142ania stosu TCP. Obecnie struktura inet_connection_sock jest wsp\u00f3\u0142dzielona w TCP i DCCP, co uniemo\u017cliwia wprowadzenie pewnych optymalizacji dla TCP bez przer\u00f3bek kodu DCCP. Szczeg\u00f3lnie przebudowa struktury inet_connection_sock pozwoli na bardziej efektywne wykorzystanie pami\u0119ci podr\u0119cznej procesora podczas przyspieszonej obs\u0142ugi pakiet\u00f3w dla ju\u017c ustanowionego po\u0142\u0105czenia TCP (TCP fastpath).
