kexec_file: kernel signature verification failed .但是执行未失败,内核成功加载 原因分析:【是否新引入rpm包,是否进行了安全编译选项扫描】否【定位分析】1、arm64验签使用的keyring为NULL,和内核签名keyring不符,需要使用VERIFY_USE_PLATFORM_KEYRING2、验签失败后,只有开启CONFIG_KEXEC_SIG_FORCE的情况下,才会返回...

这种特殊的内核风格仅在古代才需要,因为恐慌内核必须以与运行中的内核不同的物理地址加载,但是只有在编译时才能更改加载地址(也就是内核是不可重定位的)。 其次,kdump不会启动,因为底层的kexec_file_load系统调用在EADDRNOTAVAIL中失败。如果系统无法分配一个或多个缓冲区来将惊慌内核加载到RAM中,则会发生这种情况。请...
CONFIG_KEXEC_FILE in the linux kernel requires X86_64. Right now unfortunately it seems like we're stuck on x86 unless we either use the regular kexec or we port KEXEC_FILE over to the other architectures like arm or powerpc.hugelgupf changed the title KEXEC_FILE only works on X86_64 ...

MAINTAINERS: add kexec_core.c and kexec_file.c Browse files In the below commits kexec.c was split to kexec.c, kexec_file.c and kexec_core.c. commit a43cac0 ("kexec: split kexec_file syscall code to kexec_file.c") commit 2965faa ("kexec: split kexec_load syscall from kexec ...
本文以Alibaba Cloud Linux 3系統為例,介紹了通過配置crash_kexec_post_notifiers參數來解決系統未產生vmcore檔案的問題。 作業系統限制 Alibaba Cloud Linux 3 Anolis OS 8.x 問題現象 當系統發生Panic且crash_kexec_post_notifiers參數值為Y時,沒有產生vmcore檔案。
