Subject: [PATCH proxmox-ebpf 0/3] add proxmox-ebpf library
Date: Wed, 2 Sep 2026 14:32:26 +0200 [thread overview]
Message-ID: <20260902123229.638967-1-h.laimer@proxmox.com> (raw)
proxmox-ebpf holds the eBPF programs and the code to load and drive
them, grouped into subsystems. It is a library only, whoever needs a
subsystem pulls in just that one through a cargo feature and calls it
from their side. This series is the shared part, the actual
subsystems come as their own series on top.
The core is the shared subsystem code. It takes care of the whole
lifecycle, from loading and attaching per interface to pinning in
bpffs and tearing down again, so nothing has to keep running and each
call picks up where the last one left off. Updates are handled too,
the compiled object is hashed at build time and that hash plus a
schema version are recorded per subsystem, so a call can tell what
changed. A changed program is swapped onto the existing links without
interrupting traffic, a changed map schema gets a teardown and
rebuild. The BPF C code is also built natively against a small shim,
so the parsing and packet building logic can be tested without a
kernel. Packaging is debcargo like the other rust crates.
proxmox-ebpf:
Hannes Laimer (3):
add the shared tc subsystem code
tests: add a native harness for the BPF C programs
debian: package the crate as a rust library
