Introduces the headline feature of the kernel catalog: pulling a kernel
bundle over HTTP without any local build step.
Catalog format (internal/kernelcat/catalog.go):
- Catalog { Version, Entries } + CatEntry { Name, Distro, Arch,
KernelVersion, TarballURL, TarballSHA256, SizeBytes, Description }.
- catalog.json is embedded via go:embed and ships with each banger
binary. It starts empty (Phase 5's CI pipeline will populate it).
- Lookup(name) returns the matching entry or os.ErrNotExist.
Fetch (internal/kernelcat/fetch.go):
- HTTP GET with streaming SHA256 over the response body.
- zstd-decode (github.com/klauspost/compress/zstd) -> tar extract into
<kernelsDir>/<name>/.
- Hardens against path-traversal tarball entries (members whose
normalised path escapes the target dir, and unsafe symlink
targets) and sha256-mismatch downloads; any failure removes the
partially-populated target dir.
- Regular files, directories, and safe symlinks are supported; other
tar types (hardlinks, devices, fifos) are silently skipped.
- After extraction, recomputes sha256 over the on-disk vmlinux and
writes the manifest with Source="pull:<url>".
Daemon methods (internal/daemon/kernels.go):
- KernelPull(ctx, {Name, Force}) - lookup in embedded catalog, refuse
overwrite unless Force, delegate to kernelcat.Fetch.
- KernelCatalog(ctx) - return the embedded catalog annotated per-entry
with whether it has been pulled locally.
RPC: kernel.pull, kernel.catalog dispatch cases.
CLI:
- `banger kernel pull <name> [--force]`.
- `banger kernel list --available` prints the catalog with a
pulled/available STATE column and a human-readable size.
Tests: fetch round-trip (extract + manifest + sha256), sha256 mismatch
rejection with cleanup, missing-vmlinux rejection, path-traversal
rejection, HTTP error propagation, catalog parsing, lookup,
pulled-status reconciliation. All 20 packages green.
