ucode-mod-bpf: add map info method and map type constants

2026-07-20T08:43:36Z

Scripts need the map type to know how to interact with a map, e.g. per-CPU value handling or keyless queue/stack semantics. Add an info() map method returning type, key/value size and max_entries, along with BPF_MAP_TYPE constants for comparison. Signed-off-by: Felix Fietkau

ucode-mod-bpf: add ring buffer and perf event buffer support

2026-07-20T08:43:36Z

Add consumer support for BPF_MAP_TYPE_RINGBUF and BPF_MAP_TYPE_PERF_EVENT_ARRAY maps. ringbuf(callback) and perf_buffer(callback, pages, lost_callback) map methods return a buffer resource with fileno, poll and consume methods. The fileno method exposes the epoll fd and matches the interface uloop.handle() expects, so a buffer can be passed directly to uloop for event loop integration. The ring buffer callback receives the sample data and may return a negative integer to stop consumption; the perf callbacks additionally receive the CPU number. Signed-off-by: Felix Fietkau

ucode-mod-bpf: add map-in-map and prog array support

2026-07-20T08:43:36Z

Updates on array/hash-of-maps and prog array maps take the fd of the inner object as a 4-byte value. Accept bpf.map and bpf.program resources as map values and convert them to their fd. Lookups on map-in-map types return the inner map id; add open_map_id and open_program_id to obtain a usable object from such an id. Signed-off-by: Felix Fietkau

ucode-mod-bpf: add support for keyless maps

2026-07-20T08:43:36Z

Queue and stack maps have zero-sized keys and require a NULL key pointer; the kernel rejects any non-NULL key with EINVAL, making these maps unusable. Accept a null key argument on maps without a key, mapping get() to peek, set() to push and delete() with return to pop. Signed-off-by: Felix Fietkau

ucode-mod-bpf: add per-CPU map support

2026-07-20T08:43:36Z

Lookup, update and lookup-and-delete on per-CPU maps use buffers of roundup(value_size, 8) * num_possible_cpus bytes. The previous code sized buffers for a single value, so get() on a per-CPU map made the kernel overflow the stack buffer and set() passed undersized data. Track the map type and size the buffers accordingly. get() and delete() with return now yield an array with one value per CPU, set() accepts either such an array or a single value replicated to all CPUs.

ucode-mod-bpf: fix error reporting in tc hook setup

2026-07-20T08:43:36Z

Failures in the detach path returned NULL without recording any error state, so error() reported a stale or empty error. Attach failures reported a hardcoded ENOENT regardless of the actual cause. Record errno for all failures; if_nametoindex, bpf_tc_attach and bpf_tc_detach all set it. Signed-off-by: Felix Fietkau

ucode-mod-bpf: fix stale errno when rodata map is missing

2026-07-20T08:43:36Z

bpf_object__next_map does not set errno when it runs out of maps, so the reported error code was whatever errno happened to hold. With errno 0 the failure was invisible to error(). Report ENOENT instead. Signed-off-by: Felix Fietkau

ucode-mod-bpf: fix unaligned access in integer iterator

2026-07-20T08:43:36Z

The iterator key buffer is a flexible array member placed directly after a bool, leaving it without natural alignment for the u32/u64 loads in next_int. Copy the key via memcpy instead of dereferencing a misaligned pointer, which traps on strict-alignment targets. Signed-off-by: Felix Fietkau

ucode-mod-bpf: fix key/value aliasing in map argument conversion

2026-07-20T08:43:36Z

uc_bpf_map_arg converted integer arguments through a single static buffer. When map set was called with both an integer key and an integer value, the second conversion overwrote the first, so the element was written at the wrong key. Convert into a caller-provided buffer instead. Signed-off-by: Felix Fietkau
