Live Patching Now Available For Linux New submitter cyranix writes "You
may never have to reboot your Linux machine ever again, even for kernel
patching," and excerpts from the long (and nicely human-readable)
description of newly merged kernel code that does what Ksplice has for
quite a while (namely, offer live updating for Linux systems, no
downtime required), but without Oracle's control. It provides a basic
infrastructure for function "live patching" (i.e. code redirection),
including API for kernel modules containing the actual patches, and
API/ABI for userspace to be able to operate on the patches (look up what
patches are applied, enable/disable them, etc). It's relatively simple
and minimalistic, as it's making use of existing kernel infrastructure
(namely ftrace) as much as possible. It's also self-contained, in a
sense that it doesn't hook itself in any other kernel subsystem (it
doesn't even touch any other code). It's now implemented for x86 only as
a reference architecture, but support for powerpc, s390 and arm is
already in the works (adding arch-specific support basically boils down
to teaching ftrace about regs-saving).
