Public bug reported: This is a follow-on request of bug:
HWE kernels should support eBPF CO-RE https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926330 [Availability] - Package is already available in all Ubuntu versions. - This is a backported version (Impish) to Bionic and Focal [Rationale] - Current package dwarves-dfsg is old in Ubuntu Bionic and Focal. - HWE kernel compilation needs recent "pahole" binary to encode BTF[1] information. - After talking to SRU team members, updating dwarves-dfsg seemed risky. - Creating a new package containing only the new "pahole" tool binary is the best option. - Kernel HWE compilations will need to use this package, so it has to be in main repository (as kernels builds depend on main only). [Security] - This package is already stable and exists in Ubuntu. [Quality assurance] - This package is already stable and exists in Ubuntu. [Dependencies] - Same dependencies as dwarves-dfsg package (already satisfied). [Standards compliance] - This package is already stable and exists in Ubuntu. [Maintenance] - SRUs for dwarves-dfsg package within Impish should be applied to this package as well. [Background information] Bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926330 contains more information about why this is needed. I have been maintaining BTFHUB (https://github.com/aquasecurity/btfhub) in order to generate BTF files to each existing Ubuntu kernel but I feel that a simple change, like adding a recent pahole tool to the main archive in Bionic and Focal, is enough to resolve a VERY BIG problem for eBPF applications to run in HWE kernels in those Ubuntu versions. A very complete explanation on why BTF is needed for eBPF to be portable among different kernels currently exists at: https://github.com/aquasecurity/btfhub/tree/main/tools. Projects that would already benefit from this change: - Microsoft: Sysmon Tools for Linux - Microsoft: Inspektor Gadge - Elastic: They're working together with us upstream - Aqua Security: libbpfgo & tracee-ebpf - All BCC libbpf-tools and many more. ---- [1] https://www.kernel.org/doc/html/latest/bpf/btf.html ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1949286 Title: [MIR]: Include dwarves-dfsg-hwe package into Bionic and Focal Status in linux package in Ubuntu: New Status in linux source package in Bionic: New Status in linux source package in Focal: New Bug description: This is a follow-on request of bug: HWE kernels should support eBPF CO-RE https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926330 [Availability] - Package is already available in all Ubuntu versions. - This is a backported version (Impish) to Bionic and Focal [Rationale] - Current package dwarves-dfsg is old in Ubuntu Bionic and Focal. - HWE kernel compilation needs recent "pahole" binary to encode BTF[1] information. - After talking to SRU team members, updating dwarves-dfsg seemed risky. - Creating a new package containing only the new "pahole" tool binary is the best option. - Kernel HWE compilations will need to use this package, so it has to be in main repository (as kernels builds depend on main only).
