Mtundu wokhazikika wa FreeBSD 14.0 ufika ndipo izi ndi zake zatsopano

FreeBSD

FreeBSD ndi njira yotsegulira gwero.

Pomaliza, a mtundu watsopano wa FreeBSD 14.0, yomwe imabwera pambuyo pochedwa pang'ono komanso patangodutsa zaka ziwiri ndi theka kuchokera pamene FreeBSD 13.0 inatulutsidwa.

FreeBSD 14 ndiye mndandanda womaliza wa polojekitiyi yomwe idzakhala ndi chithandizo cha machitidwe a 32-bit, Chifukwa chake, mtundu wotsatira wadongosolo, womwe udzakhala "FreeBSD 15", sudzakhalanso wogwirizana ndi nsanja za 32-bit hardware.

Musanapitirire ku mfundo zazikulu pakumasulidwa kwatsopanoku, ndikofunikira kunena kuti woyang'anira mtundu wa FreeBSD yatumiza chenjezo lokhudza zinthu zomwe zingasinthidwe kuchokera kunthambi yapitayi. Kuphatikiza apo, pakhoza kukhala zovuta pakukonza kusintha kwa master.passwd: popeza mu FreeBSD 14.0 chipolopolo cha csh chidasinthidwa ndi sh, kusintha kusintha kwa /etc/ kudzakupangitsani kusintha mzere wogwiritsa ntchito /etc/master.passwd, zikunenedwa kuti kusinthaku kuyenera kukanidwa, apo ayi mzere wokhala ndi mawu achinsinsi opanda kanthu udzayikidwa.

Zatsopano Zatsopano mu FreeBSD 14

Popeza tachenjeza kale za zovuta zomwe zingasinthidwe kuchokera kunthambi yapitayi, ndi nthawi yoti muyambe ndi zatsopano zomwe zaperekedwa mu FreeBSD 14 ndi imodzi mwazo, monga tafotokozera mu chenjezo pamwambapa, Chigoba chosasinthika cha wogwiritsa ntchito mizu ndi "sh", chomwe chili ndi ntchito zingapo zatsopano zopangidwira kugwiritsidwa ntchito molumikizana.

Kusintha kwina komwe kumawonekera ndi pKwa zida za NVME, momwe driver wa "nda". Imathandizidwa ndi kusakhazikika pamapulatifomu onse. Kuti mubwezeretse dalaivala wakale wa nvd, zoikamo "hw.nvme.use_nvd=1" zimaperekedwa mu loader.conf.

Kuphatikiza pa izo, kusintha kwakukulu mu FreeBSD 14 ndikusintha kwa wotumiza maimelo watsopano kukhala dma (DragonFly Mail Agent) m'malo mwa sendmail. Kusintha kumeneku kumathandizira kasinthidwe ka MTA kudzera mwa mailer.conf, kupatsa ogwiritsa ntchito chidziwitso chamakono komanso chothandiza cha kasamalidwe ka imelo.

Ikufotokozedwanso kuti Adawonjezera chida chatsopano cha "fwget" chomwe chimazindikiritsa zida zomwe mukufuna firmware ndikuyika phukusi loyenera la firmware. Pakadali pano, zida za PCI zokha ndi firmware ndizothandizidwa ndi Intel ndi AMD GPUs.

KTLS, imawonjezera chithandizo cha TLS 1.3 mathamangitsidwe a hardware kumbali yolandira. Speedup imatsimikiziridwa ndikusuntha zochitika zina zokhudzana ndi kukonza mapaketi obisika kumbali ya khadi ya netiweki.

Kundende kumalimbikitsidwa poyambitsa .include malangizo, kulola kuphatikiza mafayilo owonjezera omwe njira zawo zimatha kubisika pokweza kasinthidwe. The sysctl security.bsd.see_jail_proc parameter yakulitsidwa, mothandizidwa ndi omwe ogwiritsa ntchito osaloleka m'malo osiyana a Jail tsopano akhoza kuletsedwa kuthetsa mphamvu, kusintha patsogolo ndi kukonza njira.

Pa UFS, pamasinthidwe omwe kudula mitengo kumayatsidwa, kuyang'ana kumbuyo kwamafayilo pogwiritsa ntchito zithunzi za UFS kumaloledwa. Macheke owonjezera a hashi awonjezedwa ku ma superblocks, mamapu amagulu a silinda, ndi ma innode kuti azindikire ziphuphu.

Awonjezera fayilo ya FIRECRACKER kernel kasinthidwe njira kulola FreeBSD kuthamanga pa Firecracker virtualization system, opangidwa kuti aziyendetsa makina enieni okhala ndi mitu yochepa. Nthawi yoyambira ya FreeBSD 14 kernel yomwe ikuyendetsa Firecracker yawonjezedwa mpaka 25 milliseconds, kukulolani kuti muyambitse malo a FreeBSD ngati pakufunika kuti mugwiritse ntchito makina opangira makompyuta opanda seva.

Mwa kusintha kwina Chodziwika bwino ndi FreeBSD 14.0:

  • Mafayilo owonjezera a tarfs, omwe angagwiritsidwe ntchito ndi mafayilo a tar-zstd.
  • Onjezani chida chatsopano cha base64 kuti musindikize ndikusintha data ya base64.
  • OpenSSH yasinthidwa kukhala 9.5p1.
  • Zolemba za rc.d zimalola kugwiritsa ntchito njira ya boma, ngakhale dzina la pulogalamu (procname) ndi fayilo ya PID sizikufotokozedwa mu script.
  • Thandizo lokwezeka la NXP DPAA2 (Data Path Acceleration Architecture Gen2) maupangiri amtundu wa hardware acceleration.
  • Dalaivala wowonjezera wa igc wa olamulira a Intel I225 Ethernet, akuthandizira kuthamanga kwa 2,5Gbps.
  • The hyve hypervisor tsopano imathandizira TPM ndi GPU kudutsa.
  • FreeBSD imathandizira mpaka 1024 cores pamapulatifomu amd64 ndi arm64.
    ZFS yasinthidwa kukhala mtundu wa OpenZFS 2.2, ndikupereka kusintha kwakukulu kwa magwiridwe antchito.
  • Tsopano ndizotheka kuchita cheke chakumbuyo kwamafayilo pamafayilo a UFS omwe akuyenda ndi zosintha zofewa zolembetsedwa.
  • Zithunzi zoyeserera za ZFS tsopano zikupezeka kwa AWS ndi Azure.
  • Njira yosasinthika yowongolera kusokonekera kwa TCP tsopano ndi CUBIC.
  • Yathandizira kupanga mafayilo osinthika a 64-bit zomanga mu PIE (Position Independent Executable) mode.
  • Kutha kupititsa patsogolo mwayi wopita ku TPM (Trusted Platform Module) ndi GPU (m'malo opezeka a AMD ndi Intel chips) awonjezedwa ku Bhyve hypervisor.
  • Chiwerengero cha ma CPU cores (ma MAXCPU parameter) pamakina otengera amd64 ndi Arm64 zomangamanga chawonjezeka kuchoka pa 256 mpaka 1024.

potsiriza ngati muli chidwi kudziwa zambiri za izo, mutha kuwona zambiri mu kutsatira ulalo.

Tsitsani ndi Pezani FreeBSD 14.0

Kwa iwo omwe ali ndi chidwi chofuna kupeza mtundu watsopano, muyenera kudziwa kuti mutha kupeza zithunzi zoyikamo zomanga zosiyanasiyana. kuchokera patsamba lovomerezekamu kalilole wanu aliyense.
