NetBSD logo
NetBSD ndeimwe yeaya akawanda maOS mumhuri yeUnix ayo asina kujairika kunzwa kana kuverenga nezvazvo. Asi izvi hazvisiye padivi chokwadi chekuti inosiyaniswa nekusarudzika kwayo, kugona kumhanya pane dzakasiyana siyana dzehardware mapuratifomu uye pamusoro pezvese kutarisisa kwayo kwehutsanana uye nyore mukugadzira.
Ndokusaka Ini ndinoona zvakakodzera kugovera nhau dzekutanga kweNetBSD 10, iyo inouya mushure megore nehafu kubva pakuvandudzwa kwayo kwekupedzisira. Iyo vhezheni itsva ine kuvandudzwa kwakakosha, senge rutsigiro rwekuwana kutonga runyorwa muFFS faira system, inocherekedza mashandiro ekuita, disk encryption uchishandisa Adiantum algorithm, uye kuisirwa kweWireGuard VPN mutyairi mukernel.
Chii chitsva muNetBSD 10?
Mushanduro itsva yeNetBSD 10, sKuvandudza kwakakosha kwakaitwa kuLinux kuenderana, uye kubatanidzwa kwerutsigiro kune akati wandei nzira dzakakosha kunomira pachena paLinux inoenderana layer (compat_linux). Izvi zvinosanganisira kuwedzera rutsigiro rwechiitikofd, timerfd, POSIX nguva, preadv uye pwritev, iyo inovandudza kudyidzana uye kushanda kwezvikumbiro zvakagadzirirwa Linux nharaunda paNetBSD. Mukuwedzera, kwave kune aYakakura yekuvandudza kune madhiraivha edhiraivha yeIntel, NVIDIA uye AMD GPUs pane x86 masisitimu, pamwe neiyo subsystem nguva DRM/KMS ine Linux kernel 5.6.
Chimwe chinhu chitsva icho NetBSD 10 inopa ndeye yakawedzera hardware rutsigiro kune itsva Intel uye AMD processors, maArM mabhodhi seRaspberry Pi 4, uye yakagadziridzwa rutsigiro rwezvivakwa seMIPS. Yakawedzerwa tsigiro yezvekuchengetedza edzengedzo senge PAN (Yakarongeka Kuwana Usambofa), PA (Pointer Authentication) uye BTI (Bazi Target Identification) paArmv8-A processors.
Vakagadziridzwa zvakare akawanda echitatu-bato zvinhu senge hwindo maneja gcc, OpenSSL, postfix, tmux, OpenSSH, X.org Server, pakati pezvimwe, kushanduro dzavo dzichangoburwa. Pamusoro pazvo 17 madhiraivha emidziyo mitsva akawedzerwa, kusanganisira mahwendefa eWacom, Gigabit Ethernet yemhando dzakasiyana, pakati pevamwe.
Kubudirira kwefaira nzira cache mu kernel yakagadziridzwa, pamwe chete ne Task scheduler performance yakanyorerwa hombe.LITTLE Arm systems. Kuita kwesarudzo uye poll system yekufona kwetmpfs faira system yakagadziridzwa, uye chaiyo optimizations yakawedzerwa kune x86 uye AArch64 zvivakwa, kuvandudza I/O uye network kuita paAArch64 masisitimu.
Kune rumwe rutivi, yakashandiswa inokurumidza muti-base algorithm yekutsvaga ndangariro mapeji, Kutsvaga mapeji endangariro akachena uye akasviba akakwidziridzwa, uye fsync yemafaira makuru yakagadziridzwa zvakanyanya. Mukuwedzera, kubata kwekuvhara kwakagadziridzwa uye kushanda kweparallel execution yemabasa kwakawedzerwa.
PaNetBSD 10 Yakawedzera rutsigiro rwe disk encryption uchishandisa Adiantum algorithm, kuwana hunyanzvi hwepamusoro mumasisitimu pasina kukwidziridzwa kwehardware yeAES encryption. Otomatiki encryption yekuchinjana partitions yakagoneswa uye tsigiro yehardware encryption yekumhanyisa masisitimu yakawedzerwa pa x86 uye Arm processors.
Pamusoro pezvo, tsigiro yePOSIX.1e ACLs yakawedzerwa kuFFS faira system, inoshandiswa kuburikidza neakawedzera faira hunhu hunotakurwa kubva kuFreeBSD. Kushandisa ACL, rudzi rutsva rwefaira system inonzi FFSv2ea yakaunzwa, iyo iripo mafaira masisitimu anogona kushandurwa uchishandisa fsck_ffs utility.
Zvevamwe zvinoshandukaizvo zvinomira pachena:
- Yakawedzera WireGuard-inoenderana wg network interface kutsigira VPN paNetBSD 10.
- Iyo yakasarudzika password hashing algorithm yakashandurwa kuita Argon2id, uye iyo software yekumisikidza yeAES yakapihwa nekernel yakagadziridzwa kuti ipe nguva dzinoenderana dzekuuraya mukati mezvivakwa.
- Universal Disk Format (UDF) rutsigiro rwakavandudzwa uye rutsigiro rweZFS rwakawedzerwa kune iyo fstat utility.
- Tsigiro yeFUSE (Filesystem muUserspace) yakawedzerwa uye yakachinjika endian magadzirirwo akawedzerwa kune software RAID kuita.
- Linux-inoshamwaridzika chiitikofd uye timerfd system mafoni akaitwa, fexecve yakawedzerwa kuita mafaera mune faira descriptor, uye yakazara system mashandiro akagadziridzwa.
- Tekinoroji dzechinyakare uye vatyairi vakaita seHIPPI, FDDI, TokenRing, vatyairi veSMBFS, pakati pevamwe vakabviswa, nepo IPv6 router advertising yakaendeswa kunzvimbo yevashandisi uye maraibhurari uye vatyairi vemidziyo yenhaka yakabviswa.
Kana uri kufarira kuziva zvakawanda nezvazvo, unogona kutarisa iyo ruzivo mune inotevera chinongedzo. Kana vari avo vanofarira iyi vhezheni itsva, iwe unofanirwa kuziva izvozvo Kuisa mifananidzo ye630 MB saizi inopihwa, iyo inounganidzwa kweanopfuura makumi mashanu system architectures uye gumi nematanhatu akasiyana eCPU mhuri.
