release: 0.15.29 (eBPF execve parent-PID capture)#1124
Merged
Conversation
Carries #1123: the eBPF execve handler now reads task_struct->real_parent->tgid in-kernel (BTF-resolved TASK_OFFSETS map) so the fileless-systemd parent-lineage gate (0.15.28) actually engages in prod. The 0.15.28 re-audit found execve events carried ppid=0 in-kernel (4995/5000); every ppid came from a userspace /proc fallback that misses short-lived execs (systemd sealed-executor fexecve). Validated live on test001: comm=systemd /proc/self/fd/9 -> ppid=1 -> gate suppresses. Version bump (Cargo.toml + workspace lock + agents-install token) + CHANGELOG [0.15.29]. No code change beyond #1123 already on main. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Carries #1123 (merged): the eBPF execve handler now reads
task_struct->real_parent->tgidin-kernel via a BTF-resolvedTASK_OFFSETSmap, so the fileless-systemd parent-lineage gate (0.15.28) actually engages in prod.Why
The 0.15.28 post-deploy re-audit found
fileless:systemdstill firing on Azure. Root cause: the eBPF execve handler hardcodedevent.ppid = 0; every prod execveppidcame from a userspace/proc/<pid>/statusfallback that misses short-lived execs — notably systemd's sealed-executorfexecveof/proc/self/fd/N(audit:ppid=0on 4995/5000 execve). So the 0.15.28 gate, which needs the parent, almost never engaged.Validated live (test001, x86_64 k6.x)
