What is Snort 3?

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

What is Inspektor Gadget?

The eBPF observability tool just started reaching for the GPU.

Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

◆ Current state

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

◆ Where it's heading

Snort is adapting an inspection engine built for readable traffic to a network where most of it is not. The investment is in inferring application identity from what remains visible, and in doing so on flows the sensor joined late. Alongside that, output is becoming more machine-consumable, with appid in alert_json, binary flow state dumps, and new DNS counters. The C codebase is being hardened continuously, which suggests fuzzing and sanitizer work running behind the feature stream.

◆ Prediction

QUIC handling has moved from an extractor to an appid preference in consecutive releases while midstream detection keeps widening; extending the same treatment to more encrypted protocols is the clearest continuation these entries support.

The eBPF observability tool just started reaching for the GPU.

◆ Current state

Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.

◆ Where it's heading

Two directions run in parallel. The kernel-side surface keeps growing — SockOps, SkSKB and SkMsg program types, map pinning, non-destructive map iteration, OTel and Python stack symbolization — which makes the tool a more general eBPF runtime rather than a fixed set of gadgets. Meanwhile the output side is becoming opinionated about ecosystems it serves: v0.54.0 taught advise_networkpolicy to emit Cilium NetworkPolicy resources alongside Kubernetes ones. GPU telemetry extends the first direction past the boundary eBPF normally stops at.

◆ Prediction

The GPU work is explicitly described as an initial design laying groundwork, so expect the next releases to build actual gadgets on top of the bridge rather than to expand it further; the pinned-map plumbing added in the same release is what those gadgets would consume.
