Hello,
when I try to compile my kernel in the root console (), I get this:
| Code: | make && make modules_install
make[1]: Nothing to be done for `all'.
make[1]: Nothing to be done for `relocs'.
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h

CALL scripts/checksyscalls.sh
CHK include/generated/compile.h

ar: invalid option -- 's'

In a Konsole started as the normal user, then doing sudo su -, it works, the kernel compiles.
That's a problem very similar to my own with lspci: https://forums.gentoo.org/viewtopic-p-7482030.html#7482030.
root Konsole:
| Code: | whereis ar
ar: /bin/ar /usr/bin/ar /usr/include/ar.h /usr/share/man/man1p/ar.1p.bz2
ls -la /bin/ar
lrwxrwxrwx 1 root root 12 Jun 16 2013 /bin/ar -> /bin/busybox
ls -la /usr/bin/ar
lrwxrwxrwx 1 root root 22 Dec 25 01:29 /usr/bin/ar -> x86_64-pc-linux-gnu-ar

normal user Konsole:
| Code: | whereis ar

b0nafide had the same error message here: https://forums.gentoo.org/viewtopic-t-914546-start-0.html . But my link is ok:

| Busybox AR does not understand the options used by the kernel build. You should not be building the kernel as root anyway, so you can avoid the problem by building the kernel as a normal user. In the long term, you should probably change the Busybox configuration not to install an ar link. |

Shouldn't the busybox version used in gentoo and the kernel tools be made compatible by the gentoo devs?
Why should I make the kernel (and makeconfig, and make modules_prepare and modules_install?) as a normal user? If a normal user (or a malware started in his environment) can change part of the kernel objects in /usr/src/linux, he can get control over the whole system as soon as the new kernel is active.
What is the right way in gentoo to change the busybox config? I found one in /etc/portage/savedconfig/sys-apps and it begins with: | Code: | #
# Automatically generated make config: don't edit |

Why would they spend effort to do that when the far more featureful binutils ar works fine as-is?

You should make the kernel as an unprivileged user for the same reason you should run any complex piece of software without privilege: grant only the privileges required for the task at hand, so that any attempt to perform an unauthorized task will be blocked by the lack of privilege.
Malware running as your user can already cause significant problems if you do not enable ptrace restrictions.
Why would you let an unprivileged user modify anything in /usr/src/linux? |

Can one configure to use the binutils instead of busybox when root?
| Quote: | | unauthorized task will be blocked |
I understand that and with executing normal software, I agree.
But compiling the kernel or modifiying the objects in /usr/src/linux - isn't that a task a usual user should be unauthorized to do? The kernel that the normal user creates will have power over anything when executed later. https://wiki.gentoo.org/wiki/Kernel/Configuration#Build recommends doing it as root as well.
I am asking because I get this permission conflict:
| Code: | /usr/src/linux $ make
make[1]: Nothing to be done for `all'.
/bin/sh: scripts/basic/modules.order: Permission denied
make[1]: *** [scripts/basic/modules.order] Error 1
make: *** [scripts_basic] Error 2
|
Do I need the hardened sources to restrict ptrace? |

Maybe. Most people just avoid installing busybox ar at all, in which case binutils ar is the only one available.

Assuming no malicious action, the kernel compiled by the user will be no more or less dangerous than the kernel compiled by root. If you run the compilation as an unprivileged user who does not run bad things, the resulting kernel is fine. If you run the compilation from a root shell running under an xterm that runs as a user who runs bad things, the bad things can manipulate the xterm to affect the root shell. Running bad things is always a bad idea, whether because they can manipulate your xterm or because they can directly manipulate the generated file. If you are concerned about malware affecting the build, you must run the privileged processes only in contexts where no unprivileged process can affect them. Among other things, this means never run a root shell or sudo shell from an xterm run by a potentially infected user. Instead, vt-switch to the text console, log in there as a known clean user (root or isolated unprivileged user) and do your system maintenance there.
Normal users should not have modify permission over /usr/src/linux.
Wiki pages are written by users, some of whom may not be all that well informed about the options offered by the kernel. I still see people who do not know the kernel can create a built-in initramfs, too.

This is correct. You must write the generated objects elsewhere by setting $KBUILD_OUTPUT. See Documentation/kbuild/kbuild.txt for other variables you can set to affect the build.

No. The patch was originally written by Kees Cook and proposed for mainline, but ended up in YAMA instead of core code. |

Hi Hu,
thank you for your new thoughts about the xterm environment. Now, trying to compile as an unprivileged user in the same directory as always, .config is not found any more. I have changed its ownership to the user.
| Code: | /usr/src/linux $ make
GEN /opt/kernel/Makefile

| As a generated output, the .config file must be in $KBUILD_OUTPUT. Since generated files will be written there, $KBUILD_OUTPUT must be writable to the user. Have you done these things? |

Yes, at least now.
after make mrproper:

/opt/kernel $ echo $KBUILD_OUTPUT
/opt/kernel
/opt/kernel $ make

I think it is the job of make and perl-cleaner to check for the right tools or use the right version directly by using the whole path. |

To solve the problem with perl-cleaner, I unmerged busybox. Then I deleted the dead links in /bin and /sbin with | Code: | | find /sbin -maxdepth 1 -follow -type l -delete |
.
After running 'make mrproper' as root in /usr/src/linux, the compilation as a normal user starts. It stops at | Code: | CC kernel/itimer.o
make[3]: *** No rule to make target `/opt/kernel/include/config/hz.h', needed by `kernel/hz.bc'. Stop.
make[2]: *** [kernel] Error 2
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2

This file doesn't exist in /usr/srx/linux/config, either. |

| Strange. Out of tree builds have worked for me for years. I see both those files in my $KBUILD_OUTPUT directory. I do not see the rule that generates kernel/hz.bc. Please post the full set of commands you ran, starting with a clean /usr/src/linux tree and no output directory. This will include you creating the directory, exporting appropriate environment variables, and whichever make commands you ran. |

| Unmerge it. Remove any files left behind by the package manager. Emerge it. Before removing unmanaged files, make copies of anything you want to save. You might have a customized .config file there. |

As I said above:

Therefore, given your use of /opt/kernel for your build directory, you should put it in /opt/kernel/ with the name .config. |
