Imibuzo Ebuzwa Rhoqo

Yintoni ikernel oops kwaye yohluke njani kwi-kernel panic?

I-kernel oops yimposiso engabulaliyo kwi Linux kernel ebonisa into engalindelekanga yenzekileyo, njenge null pointer dereference okanye ukwaphulwa kofikelelo kwinkumbulo. Ngokungafaniyo ne-kernel panic, ethi imise inkqubo yonke, i-oops ivumela inkqubo ukuba iqhubeke nokusebenza kwimeko enokuthi ingazinzanga. Ukucoca i-oops kubandakanya ukuhlalutya umkhondo wokupakisha, ukuchonga imodyuli eneziphene, kunye nokuphonononga iindawo zokulahla irejista ukukhomba oyena nobangela womba.

Zeziphi izixhobo eziqhele ukusetyenziswa ukulungisa imiyalezo ye-kernel oops?

Izixhobo eziphambili ziquka dmesg yokubamba i-oops output, addr2line kunye gdb yokuguqulela idilesi yememori kwimigca yekhowudi yomthombo, kunye objdump yohlalutyo lwe-disassembly. Abaphuhlisi be-Kernel baxhomekeke kwi-ftrace, kprobes, kunye ne-KASAN yokulungisa ingxaki. Kumaqela alawula iziseko ezingundoqo, amaqonga afana ne-Mewayz anikezela ngeemodyuli ze-207 kwi-$ 19 / mo enokunceda ukulungelelanisa inkqubo yokubeka iliso kunye nokuxilongwa komsebenzi.

Ndiyifunda njani kwaye nditolike njani umkhondo we-kernel oops?

Qala ngokuchonga uhlobo lwe-oops (umzekelo, "BUG: ayikwazi ukuphatha impazamo yephepha") kunye nesalathisi somyalelo (IP/RIP) esibonisa apho impazamo yenzekile. Emva koko, jonga umkhondo wokufowuna ukuqonda indlela yophumezo ekhokelela kwimpazamo. Jonga amagama emodyuli kwizibiyeli ukuchonga ukuba umba usuka kwimodyuli elayishekayo okanye ikernel engundoqo. Iidilesi zereferensi ezinqamlezileyo kunye nokwakhiwa kwekernel yakho usebenzisa addr2line ukwenza imephu emva kwimigca yemvelaphi ethile.

Ingaba iimpazamo zekernel oops zinokuthintelwa ngokuqhubekayo?

Ngelixa ingezizo zonke iimpazamo zekernel oops ezinokuthintelwa, amanyathelo asebenzayo anciphisa kakhulu ukwenzeka kwazo. Yenza i-kernel debugging iinketho ezifana ne-KASAN, UBSAN, kunye ne-lockdep ngexesha lophuhliso ukubamba imiba kwangoko. Gcina i-kernel yakho kunye nabaqhubi behlaziywa, zivavanye iimodyuli zesiko ngokucokisekileyo, kwaye ujonge iilogi zenkqubo yeempawu ezilumkisayo. Izisombululo zokubeka iliso ezizenzekelayo zinceda ukufumanisa iipateni ngaphambi kokuba zinyuke - i-Mewayz ibonelela ngeemodyuli ze-207 ezilungele ukusetyenziswa eziqala kwi-$ 19 / mo yokulandelela impilo yenkqubo ebanzi.
