man kernel_lockdown.7 是Linux手册页中关于kernel_lockdown机制的详细解释。这个机制用于增强内核的安全性,通过限制某些功能来防止潜在的攻击。 在这个手册页中,你可以找到关于如何配置和管理kernel_lockdown模式的详细信息。 确定系统是否处于lockdown模式: 你可以通过检查系统的启动参数或查看/sys/kernel/security/loc...
执行bpftrace时遇到的问题: 度娘了好久没有适合我的,后来看到一篇:bpftrace 执行失败 Operation not permitted,不是因为 kernel lockdown!By李佶澳 他是参考官网的操作:bpftrace/INSTALL.md at master · iovisor/bpftrace · GitHub 最后执行了下这两个操作,尤其是第二个后,瞬间好使...
vmware: kernel_lockdown breaks guestinfo fetching coreos/ignition#1092 Open Contributor lucab commented Sep 11, 2020 Indeed the Go logic seems to be broken in the same way, coreos/ignition#1092. Without going to kernel modules, I think there is a vsock-based alternative: https://github...

Work on the kernel lockdown feature started in the early 2010s, and was spearheaded by now-Google engineer, Matthew Garrett. The idea behind the kernel lockdown feature was to create a security mechanism to prevent users with elevetated permissions -- even the vaunted "root" account -- from...
Starting from kernel 5.4, lockdown is actually merged in the kernel. This issue is created to track its impact on bcc and tracing. We can add to proper documentation once 5.4 is released. The bcc/tracing will be impacted when lockdown co...

Kernel Density Estimation model was developed to predict the COVID-19 onset risk under two scenarios (i.e., with and without the Wuhan lockdown). The Wuhan lockdown, compared with the scenario without lockdown implementation, in general, delayed the arrival of the COVID-19 onset risk peak ...
As a result, beginning with kernel 6.2.1, openSUSE Tumbleweed will enable Kernel Lockdown whenever Secure Boot is also enabled. Microsoft’s reasons for insisting on Kernel Lockdown being enabled are easy to understand. Without it, Secure Boot is essentially useless, giving anyone who had it ...
