0.0.30 (Released December 18th, 2024)

These are some of the highlights of drgn 0.0.30. See the GitHub release for the full release notes, including more improvements and bug fixes.

This release is relatively small, as most development effort has been focused on the upcoming module API, which is expected to land in the next release.

Symbol Index and Kallsyms

Stephen Brennan continued his efforts towards making it possible to debug the Linux kernel without full DWARF debugging information. The next step in this release was adding new helpers for looking up symbols from kallsyms: load_vmlinux_kallsyms() and load_module_kallsyms(). These are built on top of a new, generic API for fast symbol lookups: drgn.SymbolIndex.

New Python 3.13 REPL

Python 3.13 added a vastly improved REPL with multiline editing, colorized output, interactive help, and more. drgn now makes use of this REPL when it is available.

Stack Tracing Through Interrupt Handlers

drgn had a longstanding bug where stack traces would stop at an interrupt handler frame. This release fixes that (as long as the kernel is configured to use the ORC unwinder).

Linux 6.13 Support

No drgn changes were required to support Linux 6.13 as of rc3.
