Syd: Ukubhala i-Kernel yohlelo lokusebenza ku-Rust [Ividiyo]

I-Syd iphrojekthi yokufisa ebonisa ukuthi iRust ingasetshenziswa kanjani ukuze kubhalwe i-kernel yohlelo lokusebenza evikelekile, esebenza kahle kakhulu - isendlalelo se-sandboxing esibamba futhi silawule amakholi wesistimu ukuvikela amasistimu okusingatha ezinqubweni ezingathenjwa. Lesi sifundo sevidiyo sihlola izinqumo zezakhiwo, iziqinisekiso zokuphepha, nemithelela yokusebenza emhlabeni wangempela yokwakha ingxenye yengqalasizinda ebaluleke kangaka ngolimi lwezinhlelo ezidizayinelwe ukwethembeka.

Emaqenjini aqhuba imisebenzi yebhizinisi eyinkimbinkimbi — kungakhathaliseki ukuthi ngezinkundla ezifana Mewayz noma amathuluzi angaphakathi angokwezifiso — ukuqonda ukuthi ukuphepha kweleveli ye-kernel yesimanje kubaluleke kangakanani. Izimiso ezisekelwe ku-Syd zazisa ngokuqondile ukuthi isofthiwe yebhizinisi iyivikela kanjani idatha, ihlukanise imithwalo yomsebenzi, futhi igcine ukuzinza abasebenzisi abangu-138,000+ abathembele kukho nsuku zonke.

Iyini I-Kernel Yohlelo Lokusebenza futhi Kungani Ibalulekile?

I-kernel yohlelo lokusebenza ihlala phakathi kwezinhlelo zesikhala somsebenzisi kanye nesistimu yokusebenza, esebenza njengonogada wezingcingo zesistimu. Ngokungafani ne-OS kernel egcwele, igxila kancane ku-sandboxing - ikhawulela lokho uhlelo lokusebenza oluthile olungafinyelela kuyo, lulungise, noma luqalise. I-Syd ithatha lo mqondo futhi iwusebenzise ngokuphelele ku-Rust, isebenzisa imodeli yobunikazi bolimi neziqinisekiso zokuphepha zenkumbulo ukuze kuqedwe zonke izigaba zobungozi.

Lokhu kubalulekile ngoba izindlela ezijwayelekile ze-sandboxing zivame ukuthembela ekusetshenzisweni okusekelwe ku-C lapho ibhafa eyodwa echichimayo noma isiphazamisi sokusebenzisa ngemva kwamahhala singafaka engcupheni wonke umngcele wokuphepha. Ngokukhetha i-Rust, iphrojekthi ye-Syd yehlisa indawo yokuhlasela kungqimba ebaluleke kakhulu yesitaki sesoftware. Ezinkundla zebhizinisi eziphethe idatha yezezimali ebucayi, amarekhodi ekhasimende, nokugeleza komsebenzi, lezi zinketho zezakhiwo zingena zibe yimiphumela yokuphepha yangempela.

Kungani Ukugqwala Kuba Ulimi Olukhethwayo Lwengqalasizinda Ebalulekile Yezokuphepha?

Ukwenyuka kwe-Rust ezinhlelweni zesistimu akuzenzekelanga. Ulimi luphoqelela ukuphepha kwenkumbulo ngesikhathi sokuhlanganisa ngaphandle kokuncika kumqoqi kadoti, okuyenza ifaneleke ngokuhlukile ukusebenza, ikhodi ebucayi yokuvikela. Iphrojekthi ye-Syd ibonisa izinzuzo ezimbalwa ze-Rust ezisebenza kabanzi ekuthuthukisweni kwesofthiwe yebhizinisi:

• Izifinyezo ezingabizi kakhulu: Amaphethini ezinga eliphezulu ahlanganiswe phansi ukuze abe ikhodi yomshini ephumelelayo, ukuze onjiniyela bangadeli ukusebenza ukuze bafundeke noma baphephe.
• Ubunikazi nokuboleka: Umhlanganisi uvimbela imijaho yedatha nezikhombi ezilengayo ngaphambi kokuthi ikhodi iqale isebenze, esusa imithombo evame kakhulu yokuba sengozini kwezokuvikela kusofthiwe yesistimu.
• Ukuvumelana ngokungesabi: I-Syd iphatha izinqubo eziningi ze-sandbox ngasikhathi sinye ngaphandle kweziphazamisi zokuvikela intambo ezikhungethe ukusetshenziswa kwe-C ne-C++.
• Isistimu yohlobo olucebile: Ukubhala ngekhodi okungaguquki ngezinhlobo kusho ukuthi amaphutha amaningi engqondo abanjwa ngesikhathi sokuhlanganiswa kunasekukhiqizweni, okunciphisa umthwalo wokusebenza emaqenjini aphethe amasistimu ayinkimbinkimbi.
• I-ecosystem ekhulayo: Amakhreyithi okuphatha i-seccomp, ptrace, kanye ne-Linux namespace enza i-Rust isebenze kakhulu ekuthuthukisweni kwe-kernel.

"Ikhodi evikeleke kakhulu ikhodi lapho zonke izigaba zeziphazamisi zingenakwenzeka khona ngesakhiwo. Ukugqwala akukusizi nje ukubhala isofthiwe ephephile - kwenza amaphethini angaphephile angameleleki. Kunoma iyiphi inkundla ephethe imisebenzi ebalulekile yebhizinisi esikalini, lowo mehluko umehluko phakathi kokuthemba ukuphepha nokuwunjiniyela."

Ihumusha Kanjani I-Syd's Architecture ibe Ukuphepha Kwesofthiwe Yebhizinisi?

Izimiso ze-sandboxing eziboniswe ku-Syd zinokufana okuqondile kokuthi izinkundla zebhizinisi zesimanje zivikela kanjani idatha yomsebenzisi. Ukuhlukaniswa kwenqubo, ukufinyelela okunelungelo elincane, nokuhlunga ikholi yesistimu kuyimiqondo efanayo eyisisekelo enika amandla ama-architecture we-SaaS abaqashile abaningi. Uma inkundla efana ne-Mewayz isebenzela izinkulungwane zamabhizinisi ngesikhathi esisodwa kuwo wonke amamojula ahlanganisiwe angu-207, idatha yomuntu ngamunye oqashiwe kufanele ibekwe yodwa ngokuqinile - ngokomqondo kufane nendlela i-Syd ehlukanisa ngayo izinhlelo zokusebenza ezingathenjwa ohlelweni lomsingathi.

Indlela ye-Syd yokuvimbela kanye nokuqinisekisa izingcingo zesistimu ikhombisa ukuthi izinkundla zebhizinisi ezakhiwe kahle ziqinisekisa kanjani zonke izicelo ze-API, ziphoqelela izimvume ezisekelwe endimeni, kanye nokufinyelela kwedatha yokuhlola. Ividiyo ibonisa ukuthi ukuphepha akusona isici esiboshwe ngemuva kweqiniso kodwa isisekelo sezakhiwo esilukwe kuzo zonke izingqimba zesistimu.

Yini Angayifunda Amathimba Okuthuthukisa Kunjiniyela Wezinga Le-Kernel?

Ngisho noma iqembu lakho lingalokothi libhale ikhodi ye-kernel, isiyalo esiboniswe kuphrojekthi ye-Syd sinika izifundo ezibalulekile. Onjiniyela be-Kernel basebenza ngaphansi kwemikhawulo ephoqelela ukuqina kobunjiniyela okukhethekile - akukho ndawo yokuvuza kwenkumbulo, akukho ukubekezelela ukuziphatha okungachaziwe, akukho mkhawulo wemibandela yomjaho. Ukwamukela ngisho nengxenye encane yalo mcabango kuthuthukisa kakhulu ikhwalithi yekhodi yesendlalelo sohlelo lokusebenza.

Ividiyo igqamisa indlela amathuluzi kaRust - i-Clippy yokuhlanganisa, i-Miri yokuthola ukuziphatha okungachazwanga, kanye ne-cargo-fuzz yokuhlola i-fuzz ezenzakalelayo - idala ukugeleza komsebenzi okuthuthukayo lapho izimbungulu zivela khona kusenesikhathi futhi kaningi. Lawa mathuluzi afanayo nezinqubo ziyatholakala kunoma iyiphi iphrojekthi ye-Rust, noma ngabe wakha imojuli ye-kernel noma injini yebhizinisi ezishintshayo. Amaqembu aphethe imisebenzi yonkana i-CRM, ezezimali, i-HR, i-inventory, namamojula okuphatha amaphrojekthi azuza kakhulu kungqalasizinda eyakhiwe ngaleli zinga lokunakekela.

Imibuzo Evame Ukubuzwa

Iyini i-Syd futhi iyixazulula yiphi inkinga?

I-Syd iwuhlelo olusekelwe ku-Rust oludizayinelwe izinqubo ezingathenjwa ze-sandboxing kumasistimu e-Linux. Ibamba amakholi wesistimu ukuphoqelela izinqubomgomo zokuphepha, ukuvimbela izinhlelo zokusebenza ekufinyeleleni amafayela angagunyaziwe, izinsiza zenethiwekhi, noma amakhono esistimu. Ngokusebenzisa lesi sendlalelo esibalulekile sokuvikela ku-Rust kune-C, i-Syd isusa ubungozi benkumbulo obekukade kungumthombo oyinhloko wokuhlasela ngokumelene namathuluzi e-sandboxing.

Ingabe ngidinga ukwazi i-Rust ukuze ngiqonde imiqondo ye-kernel yohlelo lokusebenza?

Cha. Ngenkathi ukusetshenziswa kwe-Syd kuqondene ne-Rust-specific, imiqondo eyisisekelo - ukucatshangelwa kwekholi yesistimu, ukuhlukaniswa kwenqubo, ukusebenzisa amalungelo amancane, kanye nokuphathwa kwenqubomgomo yezokuphepha - kuwulimi-agnostic. Ividiyo ichaza lezi zimiso ngendlela ezuzisa noma yimuphi umthuthukisi noma umholi wezobuchwepheshe ophathelene nokuvikeleka kwesofthiwe, kungakhathaliseki ukuthi uluphi ulimi oluyinhloko lokuhlela.

Isebenza kanjani le mibono yokuphepha yezinga eliphansi ezinkundleni zebhizinisi ze-SaaS?

Wonke umgomo oboniswa ku-Syd ukala ufika ekuvikelekeni kwezinga lohlelo lokusebenza. Cubungula amamephu wokuhlukanisa ukuze uhlukanise abaqashi ezinkundleni zokuxhumana ezinabaqashi abaningi. Ukuhlunga ikholi yesistimu kufana nokuqinisekiswa kwesicelo se-API kanye nokusetshenziswa kwemvume. Isu lokuvikela elijulile eliboniswe kuvidiyo liyindlela izinkundla ezifana ne-Mewayz ezivikela ngayo idatha yebhizinisi ebucayi kuwo wonke amamojula ahlanganisa ezezimali, ukusebenza, izinsiza zabantu, nokuphathwa kwamakhasimende — ukuqinisekisa ukuthi umsebenzisi ngamunye, ithimba, nenhlangano ifinyelela kuphela lokho abagunyazwe ukukubona.

Ukuvikeleka nokuthembeka akukona okucatshangelwayo — kuyizisekelo zobunjiniyela. Kungakhathaliseki ukuthi uyizinqubo ze-sandboxing ezingeni le-kernel noma uphethe yonke imisebenzi yebhizinisi kuwo wonke amamojula ahlanganisiwe, izimiso zihlala zinjalo. Usulungele ukuqhuba ibhizinisi lakho endaweni eyakhiwe ngokuvikeleka kwezinga lebhizinisi nokujula kokusebenza? Qala isivivinyo sakho samahhala se-Mewayz namuhla futhi uthole ukuthi amamojula ahlanganisiwe angu-207 angakwazi kanjani ukuhlela yonke into kusukela ku-CRM kuya ku-accounting, ukuphathwa kwephrojekthi kuya ku-HR — konke ngaphakathi kwesistimu yokusebenza yebhizinisi eyodwa, evikelekile.
