N\u00eb baz\u00ebn e kodit t\u00eb FreeBSD \u00ebsht\u00eb pranuar nj\u00eb implementim i protokollit t\u00eb komunikimit Netlink (RFC 3549), i p\u00ebrdorur n\u00eb Linux p\u00ebr organizimin e nd\u00ebrveprimit mes kernelit dhe proceseve n\u00eb hap\u00ebsir\u00ebn e p\u00ebrdoruesit. Projekti kufizohet me mb\u00ebshtetjen e familjes s\u00eb operacioneve NETLINK_ROUTE p\u00ebr menaxhimin e gjendjes s\u00eb n\u00ebnsistemit t\u00eb rrjetit n\u00eb kernel. <\/p>\n

N\u00eb form\u00ebn aktuale, niveli i mb\u00ebshtetjes p\u00ebr Netlink lejon p\u00ebrdorimin n\u00eb FreeBSD t\u00eb mjetit Linux ip nga paketa iproute2 p\u00ebr menaxhimin e nd\u00ebrfaqeve t\u00eb rrjetit, caktimin e adresave IP, konfigurimin e rutimit dhe manipulimin e objekteve nexthop, q\u00eb ruajn\u00eb t\u00eb dh\u00ebna p\u00ebr gjendjen e p\u00ebrdorur p\u00ebr d\u00ebrgimin e paket\u00ebs n\u00eb pik\u00ebn e d\u00ebshiruar t\u00eb destinacionit. Pas ndryshimeve t\u00eb vogla n\u00eb skedar\u00ebt header, b\u00ebhet i mundur edhe p\u00ebrdorimi i Netlink n\u00eb paket\u00ebn e rutimit Bird. <\/p>\n

Implementimi i Netlink p\u00ebr FreeBSD \u00ebsht\u00eb realizuar si nj\u00eb modul i ngarkuesh\u00ebm i kernelit, q\u00eb sipas mund\u00ebsis\u00eb nuk prek n\u00ebnsistemet e tjera t\u00eb kernelit dhe krijon radh\u00eb t\u00eb ve\u00e7anta detyrash (tasqueue) p\u00ebr p\u00ebrpunimin e mesazheve t\u00eb marra p\u00ebrmes protokollit dhe ekzekutimin e operacioneve n\u00eb m\u00ebnyr\u00eb asinkrone. Si arsye p\u00ebr portimin e Netlink p\u00ebrmendet mungesa e nj\u00eb mekanizmi standard p\u00ebr nd\u00ebrveprim me n\u00ebnsistemet e kernelit, gj\u00eb q\u00eb b\u00ebn q\u00eb n\u00ebnsisteme dhe driver\u00eb t\u00eb ndrysh\u00ebm t\u00eb krijojn\u00eb protokollet e tyre. <\/p>\n

Netlink ofron nj\u00eb shtres\u00eb komunikimi t\u00eb unifikuar dhe nj\u00eb format mesazhesh t\u00eb zgjeruesh\u00ebm, i cili mund t\u00eb sh\u00ebrbej\u00eb si nd\u00ebrmjet\u00ebs duke bashkuar automatikisht n\u00eb nj\u00eb k\u00ebrkes\u00eb t\u00eb vetme t\u00eb dh\u00ebna t\u00eb shp\u00ebrndara nga burime t\u00eb ndryshme. P\u00ebr shembull, n\u00eb Netlink mund t\u00eb kalohen n\u00ebnsisteme t\u00eb tilla t\u00eb FreeBSD si devd, jail dhe pfilctl, t\u00eb cilat aktualisht p\u00ebrdorin thirrjet e tyre ioctl, \u00e7ka do ta thjeshtoj\u00eb ndjesh\u00ebm krijimin e aplikacioneve p\u00ebr pun\u00eb me k\u00ebto n\u00ebnsisteme. P\u00ebr m\u00eb tep\u00ebr, p\u00ebrdorimi i Netlink p\u00ebr ndryshimin e objekteve dhe grupeve nexthop n\u00eb stack-un e rutimit do t\u00eb lejoj\u00eb nd\u00ebrveprim m\u00eb efikas me proceset e rutimit n\u00eb hap\u00ebsir\u00ebn e p\u00ebrdoruesit. <\/p>\n
