我在自己的電腦上編譯 kernel module kernel 4.15.0-36-generic 程式碼僅有 static int driver_entry(void) { printk(KERN_INFO "eeeentry"); return 0; } static void driver_exit(void) { printk(KERN_INFO "Good bye"); } module_init(driver_entry); module_exit(driver_exit); MODULE_LICENSE("GPL"); 但我不知道為何 insmod 和 rmmod 時，印出的順序是相反的XD，insmod 印出 Good bye rmmod 印出eeeentry [ 131.604421] sayHello: loading out-of-tree module taints kernel. [ 131.604458] sayHello: module verification failed: signature and/or required key missing - tainting kernel [ 131.606243] eeeentry [ 151.454288] Good bye [ 324.322405] eeeentry [ 372.027624] Good bye [ 430.550556] eeeentry -------------------------------------------------------------------------- 第一次 insmod 沒有出現任何我的 printk [ 21.142600] IPv6: ADDRCONF(NETDEV_UP): ens33: link is not ready [ 21.189327] IPv6: ADDRCONF(NETDEV_UP): ens33: link is not ready [ 21.192464] e1000: ens33 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None [ 21.193253] IPv6: ADDRCONF(NETDEV_CHANGE): ens33: link becomes ready [ 77.120885] rfkill: input handler disabled [ 364.034842] sayHello: loading out-of-tree module taints kernel. [ 364.034883] sayHello: module verification failed: signature and/or required key missing - tainting kernel 然後 rmmod 出現 driver_entry 21.142600] IPv6: ADDRCONF(NETDEV_UP): ens33: link is not ready [ 21.189327] IPv6: ADDRCONF(NETDEV_UP): ens33: link is not ready [ 21.192464] e1000: ens33 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None [ 21.193253] IPv6: ADDRCONF(NETDEV_CHANGE): ens33: link becomes ready [ 77.120885] rfkill: input handler disabled [ 364.034842] sayHello: loading out-of-tree module taints kernel. [ 364.034883] sayHello: module verification failed: signature and/or required key missing - tainting kernel [ 364.039197] driver entry 請問有人遇過嗎? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 219.68.215.61 ※ 文章網址: https://www.ptt.cc/bbs/LinuxDev/M.1539617309.A.C65.html
