Spur v0.2.2

Changes since v0.2.1

• #107/#108: Set supplementary groups (video, render) for non-root job processes — fixes GPU device access when running as non-root
• #109: Replace GetNode heartbeat hack with proper Heartbeat RPC — cleaner separation of read/write paths, real telemetry in heartbeats
• #110: Sync CLAUDE.md and README.md with current codebase

Spur v0.2.1

Hotfix: fix namespace wrapper mount ordering (PR #106). Removes private /tmp mount that broke job output file visibility.

Spur v0.2.0

Spur v0.2.0

Major release with 99 commits since v0.1.0. Highlights:

Raft-based HA (PR #84, #93)

• Replaced K8s Lease leader election with OpenRaft consensus
• Works on both bare-metal and Kubernetes — unified HA
• Config: controller.peers = ["node1:6817", "node2:6817"]

Topology-aware scheduling (PR #80)

• topology/tree — fat-tree fabric-aware scheduling, minimize switch hops
• topology/block — rack-level job co-location
• Config: [topology] section with switch hierarchy

Bare-metal job isolation (PRs #100, #102, #103, #104, #105)

• UID/GID enforcement via setuid (jobs run as submitting user)
• PID + mount namespace isolation (private /tmp, /dev/shm, process view)
• GPU device restriction via selective bind-mount
• seccomp-BPF syscall whitelist (~150 syscalls, blocks ptrace/mount/bpf)
• Landlock LSM filesystem access control (kernel 5.13+)
• [isolation] config section for operator control
• Fork bomb protection (pids.max) and OOM isolation (memory.oom.group)

K8s operator improvements (PRs #85, #93, #98)

• hostNetwork, privileged, hostIPC, shmSize fields now applied to pods
• Extra device plugin resources (RDMA, InfiniBand)
• Cross-namespace SpurJob support
• Node state machine with auto-recovery from heartbeat timeout

Scheduler fixes (PR #94)

• Fixed misleading PendingReason::Priority on new jobs
• Dispatch failures now requeue instead of marking Failed
• salloc timeout + pending reason display

Binaries

• spur-v0.2.0-linux-x86_64.tar.gz — all binaries (dynamically linked, glibc 2.39+)
• spurd-static — statically linked agent (musl, works on Ubuntu 22.04+)
