samba4repo

Wrapper for SRPM building tools for Samba 4 on Fedora 37, CentOS 8 and 9

The samba here is built with the domain controller fully enabled, in the "samba-dc" packagtes. The RPMs from RHEL upstream included only stubs, they did not actually include the domain controller components, partly because those are incompatible with the default Kerberos built into Fedora and RHEL. The experiemental Samba support for that default Kerberos is tentative and not yet suitable for production.

AlmaLinux 10 builds

"epel-rpm-macros" from EPEL is needed for successful compilation. But EPEL 10 does not exist yet.

Instal tools form https://github.com/nkadel/epelrpmmacrorepo .

Git Checkout

This repository relies on extensive git submodules. When cloning it locally, use:

• git clone --recurse-submodules https://github.com/nkadel/samba4repo

NOTE: The git repos at github.com do not include the tarballs

This is for basic security reasons: you'll need to get the tarballs separaately. These can normally be pulled from the Source: references, and pulled with this command.

• make getsrc

If necessary for manual download, look at:

• https://www.samba.org/ftp/samba/

Building Samba

These are rebuilt from Fedora rawhide releases, and need to be built and installed in the following order.

• make cfgs # Create local .cfg configs for "mock".

• • centos-stream+epel-8-x86_64.cfg # Used for some Makefiles
• • centos-stream+epel-9-x86_64.cfg # Used for some Makefiles
• • fedora-37-x86_64.cfg # Used for some Makefiles
• • samba4repo-8-x86_64.cfg # Activates local RPM dependency repository
• • samba4repo-9-x86_64.cfg # Activates local RPM dependency repository
• • samba4repo-f34-x86_64.cfg # Activates local RPM dependency repository

• make repos # Creates local local yum repositories in $PWD/samba4repo

• • samba4repo/el/8
• • samba4repo/el/9
• • samba4repo/fedora/37

• make # Make all distinct versions using "mock"

Building a compoenent, without "mock" and in the local working system, can also be done for testing.

• make build

Samba 4.10 nad later has strong dependencies on additional components that may or not be built into the current Fedora releases. These are in the following submodules:

Formerly not provided by RHEL, no longer needed

* liburing-xxx-srpm
* lmdb-xxxx-srpm

• Now compiled internally by Samba, to avoid conflict with sssd

  • libtalloc-xxx-srpm
  • libtdb-xxx-srpm
  • libldb-xxx-srpm
  • libtevent-xxx-srpm

• Still needed

  • python-iso86001-xxx-srpm
  • python-nose-1.3.x-srpm/
  • python-pyasn1-xxx-srpm
  • python-setproctitle-xxx-srpm

Then build the final package.

• samba-xxx-srpm

Installing Samba ==============--

The relevant yum repository is built locally in samba4reepo. To enable the repository, use this:

• make repo

Then install the .repo file in /etc/yum.repos.d/ as directed. This requires root privileges, which is why it's not automated.

Samba RPM Build Security

There is a significant security risk with enabling yum repositories for locally built components. Generating GPG signed packages and ensuring that the compneents are in this build location are securely and safely built is not addressed in this test setup.

CentOS Overlap

CentOS 8 has published libraries such as libtalloc and libldb of sufficiently recent release for Samba 4.16. Unfortunately, they elected to discard "python3-talloc-devel" and similar components, simply to diverge from Fedora and "mark their territory". So unfortunately, those have to be built and updated from here.

Amazon Linux Compilation

Mock on CentOS and RHEL cannot compile Amazon Linux RPMS with mock. The necessary yum repositories are accessible on Amazon Linux hosts, not publicly available the way CentOS and RHEL repos are. A tentative command to build on an amazon Linux 2 host is:

• grep -l '^MOCK.-7-x86_64' srpm/Makefile | while read name; do pushd dirname $name; make MOCKS=amazonlinux-2-x86_64; popd; done
