Package: linux-source-4.19
Version: 4.19.232-1
I updated my system today, and wanted to compile the kernel.
Unfortunately, compilation this time exited with an error.
I compile the kernel with my usual routine:
> tar -xvJf linux-source-4.19.tar.xz
> cd linux-source-4.19
> cp ../linux-patch-4.19-rt.patch.xz .
> unxz linux-patch-4.19-rt.patch.xz
> patch -p1 < linux-patch-4.19-rt.patch
> make oldconfig
> make -j4 targz-pkg
Output of uname -a:
> uname -a
Linux ravenclaw 4.19.208-rt88u0 #2 SMP Fri Dec 3 21:58:08 CET 2021
x86_64 GNU/Linux
libc 2.28-10
This recent kernel update included a security fix in the BPF subsystem,
and the error break there, so I think that the securityfix might have
broken something.
