The Next Unbreakable Enterprise Kernel Developer Release (UEK-next) is the next generation of the UEK kernel based upon the upstream Linux v6.15 tag.

The UEK-next developer release allows Oracle Linux users to try out the latest developments from upstream Linux combined with Oracle UEK-specific features.

To read more about Linux kernel development at Oracle, see:

The original README for the Linux kernel along with a other useful documentation can be found at Documentation/admin-guide/README.rst

UEK-next is not supported for production use, however we will provide limited test and development support for these kernels to help validate applications and workloads.

UEK-next does not have a Secure Boot signature and as a result cannot be used on systems where Secure Boot is enabled.

The UEK-next release is built by applying UEK specific fixes on top of the latest Linux mainline release tag.

UEK-next developer releases are upstream Linux kernels with Oracle Linux patches for use to evaluate new features in upstream Linux and enable developers to experiment with the latest hardware support, and to validate application compatibility with the latest kernels.

Every UEK-next release is based on a major upstream release (e.g.: 6.13 based, 6.14 based, etc.)

• UEK-next is also now available for installation on Oracle Linux 10

• Several selftest issues identified with BPF which are also present on the mainline kernel

• Running selinux in target or enforcing mode results in syslog messages being generated

Issues found while using this release that are not present in upstream Linux may be reported using Github Issues at:

• https://github.com/oracle/linux-uek/issues

If you have kernel patches, please contribute to upstream Linux first! Patches accepted by upstream will be part of the next UEK-next build a few weeks after that kernel is released.
