Imibuzo Evame Ukubuzwa

Iyini i-kernel oops futhi ihluke kanjani ku-kernel panic?

I-kernel oops iyiphutha elingabulali ku-Linux kernel elibonisa okuthile okungalindelekile, okufana nokuyeka i-null pointer noma ukwephulwa kokufinyelela kwememori. Ngokungafani nokwethuka kwe-kernel, okumisa yonke isistimu, i-oops ivumela isistimu ukuthi iqhubeke nokusebenza esimweni esingase singazinzile. Ukulungisa iphutha kuhlanganisa ukuhlaziya umkhondo wesitaki, ukuhlonza imojuli enephutha, kanye nokuhlola ukulahlwa kwerejista ukuze ukhombe umsuka wenkinga.

Yimaphi amathuluzi avame ukusetshenziswa ukususa iphutha kumilayezo ye-kernel oops?

Amathuluzi ayinhloko ahlanganisa i-dmesg yokuthwebula oops okukhiphayo, addr2line kanye ne-gdb yokuhumusha amakheli ememori emigqeni yekhodi yomthombo, kanye objdump yokuhlaziywa kwe-disassembly. Onjiniyela be-Kernel futhi bathembele ku-ftrace, kprobes, kanye ne-KASAN ngokulungisa iphutha lesikhathi sokusebenza. Emaqenjini aphethe ingqalasizinda eyinkimbinkimbi, izinkundla ezifana ne-Mewayz zinikeza amamojula angaphezu kuka-207 ngo-$19/mo angasiza ukwenza lula ukuqapha kwesistimu nokugeleza komsebenzi wokuxilonga.

Ngiyifunda futhi ngiyihumushe kanjani i-kernel oops stack trace?

Qala ngokukhomba uhlobo lwephutha (isb., "BUG: ayikwazi ukuphatha iphutha lekhasi") kanye nesikhombi semiyalelo (IP/RIP) esibonisa lapho iphutha lenzeke khona. Okulandelayo, hlola umkhondo wekholi ukuze uqonde indlela yokwenza eholela ephutheni. Bheka amagama emojula kubakaki ukuze ubone ukuthi inkinga isuka kumojula elayishekayo noma i-core kernel. Amakheli ereferensi ehlukahlukene ane-kernel build yakho usebenzisa i-addr2line ukwenza imephu ibuyele emigqeni ethile yomthombo.

Ingabe amaphutha e-kernel oops angavinjelwa ngokuqhubekayo?

Yize kungewona wonke amaphutha e-kernel oops angavinjelwa, izinyathelo ezisebenzayo zinciphisa kakhulu ukwenzeka kwawo. Nika amandla izinketho zokulungisa iphutha ze-kernel njenge-KASAN, UBSAN, ne-lockdep ngesikhathi sokuthuthukiswa ukuze ubambe izinkinga kusenesikhathi. Gcina i-kernel yakho nezishayeli zivuselelwe, hlola amamojula angokwezifiso ngokucophelela, futhi uqaphe amalogi esistimu ukuze uthole izimpawu eziyisixwayiso. Izixazululo zokuqapha ezizenzakalelayo zisiza ukuthola amaphethini ngaphambi kokuba anyuke — I-Mewayz inikeza amamojula angu-207 alungele ukusetshenziswa aqala ku-$19/mo ukuze alandelele uhlelo oluphelele lwezempilo.
