Ibibazo bikunze kubazwa

oops ya kernel niki kandi itandukaniye he no guhagarika umutima?

Bitandukanye na kernel panic, ihagarika sisitemu yose, oops ituma sisitemu ikomeza gukora muburyo bushobora kuba butajegajega. Gukemura oops bikubiyemo gusesengura umurongo wa stack, kumenya module ikosa, no gusuzuma imyanda yanditswe kugirango umenye intandaro yikibazo.

Nibihe bikoresho bikunze gukoreshwa mugukemura ubutumwa bwa kernel oops?

Ibikoresho byibanze birimo dmesg yo gufata ibyasohotse oops, addr2line na gdb yo guhindura adresse yibuka kumurongo winkomoko yinkomoko, hamwe na objdump yo gusesengura. Abashinzwe iterambere rya Kernel nabo bashingira kuri ftrace , kprobes , na KASAN mugukemura ikibazo. Ku matsinda acunga ibikorwa remezo bigoye, urubuga nka Mewayz rutanga module zirenga 207 kuri $ 19 / mo zishobora gufasha kugenzura imikorere ya sisitemu no gusuzuma ibikorwa.

Nigute nasoma kandi ngasobanura intangiriro ya oops stack trace?

Tangira umenya ubwoko bwa oops (urugero, "BUG: udashobora gukemura ikibazo cyurupapuro") hamwe nigitekerezo cyerekana (IP / RIP) cyerekana aho amakosa yabereye. Ibikurikira, suzuma guhamagarwa kugirango wumve inzira yo gukora iganisha ku ikosa. Shakisha amazina ya module mumutwe kugirango umenye niba ikibazo gikomoka muri module iremerewe cyangwa intangiriro yibanze. Aderesi ya aderesi hamwe na kernel yawe yubaka ukoresheje addr2line gushushanya ikarita kumurongo wihariye.

Ese amakosa ya kernel oops arashobora gukumirwa mubikorwa?

Mugihe amakosa yose ya kernel oops adashobora kwirindwa, ingamba zifatika zigabanya cyane ibibaho.

Komeza intangiriro yawe hamwe nabashoferi bavugururwa, gerageza module yihariye, kandi ukurikirane sisitemu ya sisitemu kubimenyetso byo kuburira. Igenzura ryikora ryikora rifasha kumenya uburyo mbere yo kwiyongera - Mewayz itanga 207 yiteguye-gukoresha-modules guhera kuri $ 19 / mo kugirango ikurikirane ubuzima bwiza.
