* fix(rpc): Improve input validation and error handling The `rpc-server` was vulnerable to Denial of Service attacks via several RPC commands (`SET_TENSOR`, `GRAPH_COMPUTE`, etc.). Malformed messages could trigger failed assertions (e.g., invalid `ggml_type`) or out-of-bounds reads/writes leading to `GGML_ABORT` calls, crashing the server process. This PR introduces robust input validation and replaces `abort()` calls with graceful error handling: - **Type Validation:** `deserialize_tensor` now checks if the `tensor->type` is within the valid `GGML_TYPE_COUNT` range *before* calling `ggml_new_tensor_4d`. Returns `nullptr` on invalid type. - **Bounds Checks:** Replaced `GGML_ABORT` in `set_tensor`, `set_tensor_hash`, and `get_tensor` handlers with error logging and returning `false` when data/offset parameters are out of buffer bounds. - **Size Checks:** Added safe arithmetic checks (for overflow) in `graph_compute` when calculating required message sizes based on client-provided `n_nodes` and `n_tensors`. Returns early if the reported sizes conflict with the actual message size or would lead to overflow. - **Error Propagation:** - `create_node` now checks for `nullptr` return values from `deserialize_tensor` and its recursive calls, propagating `nullptr` upwards on failure. Uses `find` instead of `at` for safer map access. - `copy_tensor` now checks for `nullptr` from `deserialize_tensor` and sets the response status to failure if deserialization or bounds checks fail. - `graph_compute` now checks for `nullptr` return from `create_node` and returns failure status correctly. The final return value now reflects the actual computation status. These changes improve the RPC server's resilience against malformed client requests, preventing crashes and ensuring errors are handled more gracefully.

This ambiguity made error handling difficult for the caller (`graph_compute`). This commit clarifies the meaning of nullptr: - `graph_compute` now checks if the input 'id' was non-zero when `create_node` returns nullptr, correctly identifying failures versus intentional null links. - `create_node` avoids recursive calls for zero IDs and propagates nullptr unambiguously on failure during recursion. Signed-off-by: Ville Vesilehto <[email protected]> * refactor(rpc): initial zero check in create_node The caller (`graph_compute`) already checks `id != 0` when handling a `nullptr` return from `create_node`, correctly distinguishing intentional null links from actual errors. This makes the initial `if (id == 0)` check redundant. Also removes the log message when a tensor ID is not found in the provided map which was added in this branch. Signed-off-by: Ville Vesilehto <[email protected]> * fix(rpc): Handle get_alloc_size failure in server Check the return value of `server.get_alloc_size` in the RPC server loop. If the call fails, return early to close the connection. Signed-off-by: Ville Vesilehto <[email protected]> * refactor(rpc): input size validation in graph_compute Removes detailed, step-by-step size calculations and overflow checks in favor of simpler direct comparisons, assuming 64-bit overflow is unlikely. Signed-off-by: Ville Vesilehto <[email protected]> * refactor(rpc): remove extra status code setting Removes the explicit setting of `response.result = GGML_STATUS_FAILED` when `create_node` returns `nullptr` within `graph_compute`. Primary signal is the `false` return value in case of failure. Signed-off-by: Ville Vesilehto <[email protected]> * refactor(rpc): remove redundant check for tensor->type Breaks CI on ubuntu-cpu-make. Tensor type is uint32_t, thus the check is not needed.
