selftests/bpf: check null propagation only neither reg is PTR_TO_BTF_ID

2023-01-24T06:17:58+00:00

[ Upstream commit cedebd74cf3883f0384af9ec26b4e6f8f1964dd4 ]

Verify that nullness information is not porpagated in the branches
of register to register JEQ and JNE operations if one of them is
PTR_TO_BTF_ID. Implement this in C level so we can use CO-RE.

selftests: set the BUILD variable to absolute path

2023-01-18T10:42:00+00:00

commit 5ad51ab618de5d05f4e692ebabeb6fe6289aaa57 upstream.

The build of kselftests fails if relative path is specified through
KBUILD_OUTPUT or O= method. BUILD variable is used to determine
the path of the output objects. When make is run from other directories
with relative paths, the exact path of the build objects is ambiguous
and build fails.

	make[1]: Entering directory '/home/usama/repos/kernel/linux_mainline2/tools/testing/selftests/alsa'
	gcc     mixer-test.c -L/usr/lib/x86_64-linux-gnu -lasound  -o build/kselftest/alsa/mixer-test
	/usr/bin/ld: cannot open output file build/kselftest/alsa/mixer-test

Set the BUILD variable to the absolute path of the output directory.
Make the logic readable and easy to follow. Use spaces instead of tabs
for indentation as if with tab indentation is considered recipe in make.

selftests: Fix kselftest O=objdir build from cluttering top level objdir

commit 29e911ef7b706215caf02a82b0d3076611d6abe8 upstream.

make kselftest-all O=objdir builds create generated objects in objdir.
This clutters the top level directory with kselftest objects. Fix it
to create sub-directory under objdir for kselftest objects.

selftests: Use optional USERCFLAGS and USERLDFLAGS

2023-01-18T10:41:46+00:00

commit de3ee3f63400a23954e7c1ad1cb8c20f29ab6fe3 upstream.

This change enables to extend CFLAGS and LDFLAGS from command line, e.g.
to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static

USERCFLAGS and USERLDFLAGS are documented in
Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst

This should be backported (down to 5.10) to improve previous kernel
versions testing as well.

ktest.pl minconfig: Unset configs instead of just removing them

2023-01-18T10:41:45+00:00

commit ef784eebb56425eed6e9b16e7d47e5c00dcf9c38 upstream.

After a full run of a make_min_config test, I noticed there were a lot of
CONFIGs still enabled that really should not be. Looking at them, I
noticed they were all defined as "default y". The issue is that the test
simple removes the config and re-runs make oldconfig, which enables it
again because it is set to default 'y'. Instead, explicitly disable the
config with writing "# CONFIG_FOO is not set" to the file to keep it from
being set again.

With this change, one of my box's minconfigs went from 768 configs set,
down to 521 configs set.

kest.pl: Fix grub2 menu handling for rebooting

2023-01-18T10:41:45+00:00

commit 26df05a8c1420ad3de314fdd407e7fc2058cc7aa upstream.

grub2 has submenus where to use grub-reboot, it requires:

  grub-reboot X>Y

where X is the main index and Y is the submenu. Thus if you have:

menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ...
	[...]
}
submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ...
        menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ...
                [...]
        }
        menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ...
		[...]
        }
        menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ...
                [...]
        }

And wanted to boot to the "Linux test" kernel, you need to run:

 # grub-reboot 1>2

As 1 is the second top menu (the submenu) and 2 is the third of the sub
menu entries.

Have the grub.cfg parsing for grub2 handle such cases.
