2026-05-232c fix epoll_create and pidfd_open flags in BPF codegenPaul Buetow
epoll_create(size) was recording size (args[0]) as flags — hardcode to 0 since the syscall has no flags argument. pidfd_open(pid, flags) was recording pid (args[0]) as flags — use args[1] instead. Add test fixtures and codegen tests that verify the correct argument indexes and reject the old wrong ones. Regenerate generated_tracepoints.c. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

2026-05-06add Dockerfile and Rocky Linux 9 build docsPaul Buetow
Introduces a Docker-based build path so ior can be compiled on any Linux host without a native Rocky 9 toolchain setup: - Dockerfile: Rocky 9 minimal image with Go (version from ARG, default from go.mod), static libelf/libzstd built from source, libbpfgo at v0.9.2-libbpf-1.5.1, and mage; CMD runs mage generate + mage all against the repo root mounted as a volume. - scripts/build-with-docker.sh: reads GO_VERSION from go.mod, passes it as --build-arg to docker build, mounts tracefs and BTF into the container, writes the binary to the repo root. - Magefile.go: adds BuildDocker target that wraps the script. - README.md: simplified to the two build paths (Docker + native) with links to docs/; removed GOTOOLCHAIN=auto throughout. - docs/build-rocky-linux-9.md: full manual Rocky 9 steps, libbpfgo toolchain setup/rollback, compile-once-run-everywhere explanation, and timing semantics. - docs/tui-reference.md: complete TUI hotkey reference, recording mode details, and the .ior.zst vs Parquet trade-off table. - AGENTS.md: removed GOTOOLCHAIN=auto from all build commands. - internal/c/generated_tracepoints.c: regenerated against the host kernel.

2026-05-02fix BPF tracepoint context type for RHEL 9 stock kernelPaul Buetow
The BPF handler generator emitted struct trace_event_raw_sys_enter/ trace_event_raw_sys_exit (the BTF-blessed aliases). RHEL 9 carries an rt-tree backport that adds preempt_lazy_count to struct trace_entry, which widens those aliases by 8 bytes and shifts args/ret. The actual tracepoint context the kernel hands the program is still syscall_trace_enter / syscall_trace_exit, where the offsets did not move. Programs typed against the wider alias read past max_ctx_offset and the verifier rejects the attach with EACCES. Switching the generator to emit syscall_trace_enter/exit lines up with the real context on RHEL 9 (and is identical on every other distro, since the two structs only diverge there). Same fix bcc shipped in iovisor/bcc#4920 and inspektor-gadget did in inspektor-gadget#2546. Field accesses (ctx->args[N], ctx->ret) are unchanged. Verified end-to-end on Rocky Linux 9.7 stock 5.14.0-611.5.1.el9_7 (no kernel-ml needed) and Fedora 6.19. README rewritten accordingly: drops the elrepo kernel-ml step and the trailing 'permission denied' troubleshooting paragraph; adds a historical note explaining why the old workaround existed.
