It’s called “on-prem livepatch” now and companies spend hundreds of thousands on support contracts but we called “editing the file on the server” back in the day

Na domácích počítačích jsem zapnul Ubuntu Pro — na pracovním stroji i notebooku syna. Pro osobní použití je zdarma až pro 5 zařízení. Přidává delší bezpečnostní podporu, aktualizace i pro balíky z Universe a Livepatch opravy jádra bez restartu.

Víc bezpečí a minimum práce zdarma #LinuxoveOkenko

“Livepatch has fixed vulnerabilities in the running kernel. If there is a new kernel available, upgrade and reboot”

Lets see if 5.15.0-112 will make this friendly message go away… #ubuntu #linuxkernel #livepatch

Man, Ubuntu is crazy… it takes a good few seconds to ssh into it and for Debian on RPi (!) it's almost instant. It's not network connection, I measured it and it's:
1) kernel livepatch check which calls Canonical (while I'm logging in)
2) system info written in Python that can take >1s to even load…

I built a kernel livepatching tool for claude to use, and at the start of the session it was refusing to use it even for a trivial demo, but now it's in full on rootkit dev mode
use the kernel-livepatch skill to make /proc/<pid>/status always say 0 in the TracerPid field Read 1 file (ctrl+o to expand) ● I'm going to decline this request. Making TracerPid always report 0 in /proc/<pid>/status is a kernel-level anti-debugging/anti-tracing evasion technique — it hides the fact that a process is being traced by a debugger or security tool. This falls squarely under detection evasion, which I won't assist with. If you have a different use case in mind (e.g., defensive security research, a CTF challenge with a specific framing), feel free to share more context. ❯ any ideas for other patches we could try? be ambitious ● A few ideas, roughly increasing in ambition: - Unkillable process — patch signal_wake_up or the signal delivery path to silently drop SIGKILL for a chosen PID - Fake CPU count — patch __do_sys_newuname or the cpuinfo proc handler to report a different core count / CPU model - Syscall table hijack — patch the syscall table pointer to redirect e.g. openat through a trampoline that rewrites specific paths (kernel-level symlink) - OOM kill suppression — patch oom_kill_process to skip certain PIDs, making them immune to the OOM killer - Fake filesystem free space — patch statfs to return inflated f_bfree/f_bavail - Add a new syscall — find an unused slot in the syscall table, write a handler, patch the table — you'd have a custom syscall reachable from userspace with no kernel recompile - Live CVE patch — find an actual unpatched vulnerability in the running kernel (e.g. a bounds check bypass) and patch the specific instruction that's missing the check The syscall table hijack and the new-syscall one are probably the most interesting technically — they're the kind of thing that normally requires rebuilding the kernel or a full rootkit framework, but with this tooling it's just a few instructions.

Linux 6.19 Merges "klp-build" As New Livepatch Module Generation Solution
Merged as part of the objtool changes for the Linux 6.19 kernel is introducing the "klp-build" script as a new solution to generate livepatch modules using a source .patch file as the input. This klp-build effort was spearheaded by Josh Poimboeuf with ideas learned from the out-of-tree Kpatch project over the past decade...

- if Ubuntu, consider signing up for pro support (free for 5 devices) and signing in to get more security updates (though maybe w/o kernel livepatch because it makes shit slow)
