DNS queries are not working in busybox.

Description of the problem:

1. /etc/resolv.conf is populated with name servers
2. Route to name server is set (checked with ping)
3. nslookup/ping fails for any domain (but the name server address is correct in nslookup)

Possible cause:
Statically-linked glibc programs (like busybox in this case) can't use getaddrinfo / gethostbyname functions without providing a libnss library (which is dynamically loaded).

Hey there

Are you interested in merging my work on memtester + powerpc build?
I've changed the scripts so it could build for powerpc and x86 / amd64 without breaking anything. Of course i'd have to merge your recent changes too. Also i've seperated creating iso and bootloader into seperate scripts with a switch in the main script so its cleaner.

Im more interested in contributing and being a part of MLL rather than creating my own fork. I'd be mainly improving things, add more overlays and support other exotic hardware if requested to.

greetings

With the newly introduced autorun functionality it is now possible to decide what we want to run on boot. If an overlay bundle puts executable script in /etc/autorun, this script will be executed by MLL at boot time.

Right now the DHCP network functionality is utilizing this autorun functionality as PoC. The corresponding autorun script is currently part of the rootfs structure. However, it is possible to create new overlay bundle (e.g. dhcp_client) and externalize all DHCP client functionality there. In this way MLL will become more modular and the rootfs structure will become a little bit simpler.

The nweb project is direct descendant of the original nweb HTTP server developed by Nigel Griffiths.

This HTTP server is so small, easy to compile and easy to use, that it is perfect candidate to become the first overlay bundle enabled by default in the build process since it has no external dependencies and its build process is simple and fast.

As minimum, this should become an overlay bundle. The entire source may be hosted as part of the MLL project since the original license is in the public domain and all other project references that I found either don't explicitly set license or they are in the public domain as well.

I have tested manually all overlay bundles with the latest changes on Ububtu 16.04. Unfortunately they all seem to be broken due to some GCC issues with the recently introduced -specs functionality. Going back to older kernel and glibc is not an option (the project moves ahead).

Hello, I have been working recently on a separate branch of minimal to add support of Nano, then to push it into the master branch for everyone to use, but I'm having trouble installing Ncurses and putting the libraries in the /lib folder required by Nano. Like it will fail at a mouse problem and won't generate the libraries, with the worst part being the file that's broken builds the libraries. Think you could take a look at it and see if I might've typed something wrong, because I checked the Internet and used Linux From Scratch as a source and nothing seemed to be wrong.
My Fork: https://github.com/AwlsomeAlex/minimal
(I know this has nothing to do with yours, but I wish to contribute to yours with Nano and eventually dialog being something I would like to implement.)

Hi,

I am using your script to build a minimal linux file system. However, I met the following problem when run 07_build_busybox.sh:

miscutils/lib.a(microcom.o): In function microcom_main': microcom.c:(.text.microcom_main+0x28b): undefined reference to__poll_chk'
networking/lib.a(ifplugd.o): In function ifplugd_main': ifplugd.c:(.text.ifplugd_main+0x318): undefined reference to__poll_chk'

collect2: error: ld returned 1 exit status
make: *** [busybox_unstripped] Error 1

Have you any sense what is wrong?

ps. if I did not spefic the CONFIG_SYSROOT, denote line 41 in 07_build_busybox.sh, these would be not errors.

Thanks in advance

Hello!
Dead project?
проект мъртъв?

I found multiple issues with the default build of MLL on StotinkaOS 7.3 (derived from CentOS 7.3).

• GLIBC build causes buffer overflow in the linker (/bin/ld) when the default language is not English. The easiest workaround is to set the LANG shell variable to en_US.UTF-8 before building GLIBC. This bug has already been reported.
• BusyBox cannot be compiled because the linker was not configured to use sysroots. One possible solution is to introduce additional build step in MLL where the binutils package is configured with explicit option to use sysroots and then we can use this new linker instead of the default one. This approach has already been analyzed and implemented by Jeff (refer to the mail thread from Feb 16-17).

Mounting NTFS USB drive fails with error : "failed: invalid argument"

Thanks,

BusyBox build failed on Ubuntu 16.04 64-bit default installation. The build failed on two Ubuntu 16.04 systems. Ubuntu 14 was not affected by this issue.

Dropbear is a relatively small SSH server and client.

One use case is the DHCP client funstionality.

If we have the DHCP client functionality as overlay bundle, there is high chance that it won't work properly on real hardware because the kernel provides minimal configuration and as result many devices may not be recognized, including the boot device. In this case all overlay bundles won't be accessible.

So, if we want to ensure that certain functionality is really there, it should be part of the initramfs structure.

This would require some major reachitecturing because the overlay bundles should be available before the initramfs structure has been packaged. Another challenge is to redesign the overlay bundles so that they generate independent structure which then could be merged with the initramfs structure.

It was reported that isohybrid is part of the syslinux-utils package. This should be investigated further and either the dependency list should be updated, or the isohybrid functionality should be removed from MLL.

During the build the following errors happen:
*** GENERATE ROOTFS BEGIN *** Preparing initramfs work area... cp: cannot stat ‘/home/jeff/minimal/src/work/busybox/busybox_installed’: No such file or directory cp: target ‘rootfs’ is not a directory 09_generate_rootfs.sh: 24: cd: can't cd to rootfs cp: cannot stat ‘../src’: No such file or directory Source files and folders have been copied to '/src'. cp: cannot stat ‘/home/jeff/minimal/src/work/glibc/glibc_prepared/lib/ld-linux*’: No such file or directory Dynamic loader is accessed via '/lib'. cp: cannot stat ‘/home/jeff/minimal/src/work/glibc/glibc_prepared/lib/libm.so.6’: No such file or directory cp: cannot stat ‘/home/jeff/minimal/src/work/glibc/glibc_prepared/lib/libc.so.6’: No such file or directory cp: cannot stat ‘/home/jeff/minimal/src/work/glibc/glibc_prepared/lib/libresolv.so.2’: No such file or directory cp: cannot stat ‘/home/jeff/minimal/src/work/glibc/glibc_prepared/lib/libnss_dns.so.2’: No such file or directory Reduced the size of libraries and executables.

Right now MLL provides just minimal kernel with default functionality. It will be good to "upgrade" this by adding kernel modules and firmware. Building and packing the default modules and firmware has been implemented in the mincs branch and this functionality can be implemented as overlay bundle.

The bundle should also provide autorun script which handles properly the mdev setup.

Any ideas why a fresh build and bootup with qemu is failing with this message? (I'll do some Googleing to see what I can find...).

How install on HD using fdisk? It's possible create an extra sh file for it?

Since this project aims at building small linux image, it would be great to also support small libC backend in addition to GlibC, such as musl or another libc.

Nice project, but it lacks a package manager or at least GCC to compile additional packages. Please add it or at least provide a tutorial on how to install GCC.

Thanks!

The title says it all. The Syslinux project has been abandoned long ago and since then the GRUB project evolved significantly.

Hello, I'm trying to extract the contents of the .iso image onto a USB so I can install it onto other computers, however most programs format the USB in vFat, which I want to avoid due to OverlayFS not supporting it. Is there a way to 'flash' Minimal Linux Live onto a ext4 USB? I've tried dd, it never works. Also if not, if I were to compile the OverlayFS under 'sparse' instead of 'folder' and lets say I made 20 MB worth of changes BUT the Sparse Image is only 10 MB, would it automatically increase, or would it remain 10 MB and delete the other 10 MB?

For my application I want to run folding at home version 7. In order to download the client I need openssl. I think I see how this kind of thing works from looking at the musl-busybox scripts. Is that a good example of what would need to be done?

Hey,

I've built my own image, then tried to run it using QEmu. QEmu just stuck with no output.
then i tried to pull the offical images from website, both 32 and 64 edition does the same.

P.S:
Im running macOS Sierra

I'm talking about two types of things:

• press space or wait some seconds actions. We could either have an option of config file to:
  • choose an option and ask nothing
  • disable them and take a fixed default if the above is not technically possible
• network discovery startup: possible run on background? Buildroot 2016.05 qemu_x86_64_defconfig does it.

Those would speed up the boot process and make it more automatic.

BTW, those features are awesome... I just wish boot was faster :-)

Currently the website provides the following as the command which should be executed in order to resolve all build dependencies:

sudo apt wget make gawk gcc bc genisoimage

However, the correct command is this one:

sudo apt install wget make gawk gcc bc genisoimage

The website should be updated accordingly. Also, the information about the RAM usage should be revised and updated if needed.

This is the official 'bug issue' for #67.

The command which causes the bug is this one:

GCC is 5.4.0 on Ubuntu 16.04.
MLL kernel is 4.12.4, glibc is 2.26 and BusyBox is 1.27.1 (BTW it doesn't matter).

I'm not yet familiar with the sysroot.specs functionality (yep, my bad) and I'll be glad if anyone could assist me and figure out what the problem is and how I can fix it permanently.

I notice DNS doesn't work. We should get this working. I'm not sure what's involved yet by reading http://lists.busybox.net/pipermail/busybox/2001-November/005103.html it looks like we either have to change some compile options for busybox or add in uclibc?

The cf_cli overlay bundle currently uses hard coded value for the CF CLI URL. The problem is that the URL contains multiple = characters which break the URL parsing. This particular overlay bundle needs alternative approach for the URL parsing. One solution is to use source.

Alternatively, the overall approach regarding the URL parsing should be revised and updated in all scripts.

Hello,
Nice minimal Linux support and version...

Hello, I know I've bothered you enough but this time I found something interesting. Whenever Minimal Linux Live tries to build GLIBC on an x86 host, it always fails in the build stage, giving the error
Makefile:recipe for target 'io/subdir_lib' failed.
However further up the log I can find GLIBC throwing out errors when it's trying to compile ../sysdeps/unix/sysv/linux/posix_fallocate.c giving the error
error: bp cannot be used in asm here
}
^
I also installed all of the required dependencies for GLIBC due to me originally thinking that was the problem, but less dependencies are on my x86_64 machine and it builds fine. I also checked the kernel, everything seems to compile (headers). But I'm honestly not sure what's happening. I've provided a build log to help you out so this is less of a guessing game: (Visible problem from Lines 84,141 - 84,165).
Minimal Linux Live Build Log
Thanks.

What would be needed to be able to build a minimal Linux desktop?

For a lot of professional Linux users a system that enables you to start Firefox or Chromium and be able to switch to a terminal window/workspace without closing down the browser first would be the minimal usable graphical desktop.

The hardest part would be to get Firefox or Chromium working on a Linux+busybox system.

Any ideas how to accomplish this? I suppose the simplest route would be to use Wayland and a patched Firefox/Chromium? Or are a lot more dependencies needed for this to work?

https://wiki.archlinux.org/index.php/wayland

Multiple packages (partially) ignore the glibc sysroot and compile using the host systems libraries and includes.
One example would be the links package.

nweb example on the linker problem:

gcc --verbose $CFLAGS --sysroot=$MAIN_SRC_DIR/work/glibc/glibc_prepared $SRC_DIR/nweb23.c -o nweb

to

gcc --verbose -Wl,--verbose -Wl,--sysroot=$MAIN_SRC_DIR/work/glibc/glibc_prepared -L =/lib -L =/lib64 $CFLAGS --sysroot $MAIN_SRC_DIR/work/glibc/glibc_prepared $SRC_DIR/nweb23.c -o nweb

The second tells the linker the sysroot too and where to search for libraries (-L =/lib -L =/lib64 is very important)

Whenever I try to load Links I get the following error:

links: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

And when I check my /lib and /lib64, the library file is not present. Is there maybe a configuration workaround, or does the dependency HAVE to be added?

EDIT: Adding the --disable-zlib argument to the configuration to see what happens.

EDIT 2: That gave the same error. Any Suggestions?

Instead of downloading the kernel under work, I want to reuse an existing kernel source to help testing a hacked kernel for development.

I have implemented that at: https://github.com/************/runlinux based on this repo. Feel free to link from the README to it if deemed worthy :-)

Also if you find it interesting, I can patch this repo to do that as well: we could add a --src flag that points to the desired source to use.

The currently existing dropbear overlay bundle needs additional autorun script which properly handles the start process of the SSH server. Hints regarding the startup process can be found here. Note that these explanations have been provided for interactive console and the actual autorun process has to be slightly different.

PowerPC live images cant be build due to the static arch name in copy of the linux image path.

It would be great to make it easier for people to run on real hardware if they don't have CDs.

I have implemented it at: https://github.com/************/runlinux/blob/8da285b7ddd0f6fa8a411fa020d12bc8f5ee7ef5/runlinux#L82-L84 and could PR here.

I think the image generated by grub-mkrescue is also bootable from a CD, but I can't test that (qemu -cdrom also works in addition to -hda).

@ladiko has also implemented it at https://github.com/ladiko/minimal/blob/0b2ae8b868f1d4294d7d2dfec41b093da5696705/src/create_boot_stick.sh but at 3 lines long I think mine is simpler :-)

This is more of a discussion than an issue. What I want to do is with the mll-utils on my side project, AwlsomeLinux, and add the functionality to install/copy the OverlayFS to an actual File System (ext2 on /dev/sdxx) and have the InitramFS go into the actual filesystem, where do you recommend me looking for this information or do you know of such information? I've checked the closest things to Minimal Linux Live (Tiny Core doesn't even use OverlayFS, Alpine uses an Init Manager similar to Systemd (OpenRC), and Slax is too confusing.) Also does a Package Manager for Minimal Linux Live sound too far-fetched? Thanks!

is there any way to fix this by not patching every linux header for every linux verion to not duplicate definitions?

Currently the default download URL for Apache Felix points to online folder (accessible via HTTP) where only the latest stable version is available. This means that whenever new Apache Felix version is released, the corresponding URL in MLL becomes invalid.

Currently this doesn't cause build issues because all overlay bundles are disabled by default. Nevertheless, this should be fixed. One option is to use the Apache's online archive where (most probably) all Felix versions are available, including the latest one.

With the addition of Minimal Linux Live being Installable to other machines, would it be possible to create another user in the Installation Progress? Or even better, provide a login prompt for the root user? I tired looking around in the init (since that is where it would most likely be added) but I can't seem to find /sbin/init, which is executed after OverlayFS has been added. What file is being copied over into the OverlayFS to become /sbin/init?

Many thanks for MLL! Wonderful way of learning!
When booted from a USB device (the isohybrid version of resulting .iso), the network does work for me.
Apart from lo, ifconfig shows sit0 network device (IPv6-in-IPv4). (no eth0).
Tested on 32bit and 64bit version on different laptops.
(Tested with other linux distro, network works on these.)
Network works within qemu. ifconfig also shows lo and eth0 devices. eth0 has an ip address (given by dhcp, i suppose.)
Thanks in advance for any hints,

Just tried minimal for the first time. Very cool. One glitch: in 09_pack_rootfs.sh my build failed on "cpio -R" because my $PATH includes "./" -- which I find convenient when developing but in this case (I presume) causes the shell script to find the busybox cpio build in a previous step. I patched the script to use /bin/cpio and all completed successfully. Perhaps there are other similar vulnerabilities in the build scripts?

Seems like Redox OS no longer uses MLL as base for the Redox OS installer. In this case the Markdown readme page for MLL should be updated accordingly in order to avoid discrepancies. However, this requires some further research.

In Linux Kernel 4.10, they added more EFI support (specifically towards Apple Devices) to the configuration. However they failed to introduce a default value so whenever the 02_build_kernel.sh script is executed it hangs at the configuration section below:
APPLE_PROPERTIES
I've tried to create a sed to set a default value in the configuration but this specific setting is only found in a Kconfig table in the directory drivers/firmware/efi/Kconfig. An easy fix would to just say "Use Linux Kernel 4.9 and below!" or "Input 'n' manually." but I just wanted to bring this to your attention to see if you have any suggestions on automating this.

Theres also another one for OVERLAY_FS_REDIRECT_DIR but I haven't tested to see if adding a 'sed' command for the default config would work.
