NAME¶

kpatch-build - build script

SYNOPSIS¶

kpatch-build [options] <patch file>

DESCRIPTION¶

This script takes a patch based on the version of the kernel currently running and creates a kernel module that will replace modified functions in the kernel such that the patched code takes effect.

OPTIONS¶

-h|--help
Show this help message

-a|--archversion
Specify the kernel arch version

-r|--sourcerpm
Specify kernel source RPM

-s|--sourcedir
Specify kernel source directory

-c|--config
Specify kernel config file

-v|--vmlinux
Specify original vmlinux

-j|--jobs
Specify the number of make jobs

-t|--target
Specify custom kernel build targets

-n|--name
Specify the name of the kpatch module

-o|--output
Specify output folder

-d|--debug
Keep scratch files in /tmp
(can be specified multiple times)

--oot-module
Enable patching out-of-tree module,
specify current version of module

--oot-module-src
Specify out-of-tree module source directory

-R|--non-replace
Disable replace flag of KLP
(replace is on by default)

--skip-cleanup
Skip post-build cleanup

--skip-compiler-check
Skips check that ensures that the system compiler version and
the compiler version that built the kernel match. Skipping this
check is not recommended, but is useful if the exact compiler
version is not available or is not easily installed. Use
only when confident that the two versions of compiler output
identical objects for a given target. Otherwise, use of
this option might result in unexpected changed objects
being detected.
