tools : reject truncated GGUF tensor data in split and export tools (#30497) 
* The problem here in the repo is gguf-split can silently produce corrupted tensor output when the input GGUF file is truncated. The fix is to add tensor-data bounds checks and short-read checks in gguf-split.cpp and export-lora.cpp, and a regression test that checks truncated input is rejected and valid tensor data is preserved.#

* Bug : GGUF-split can silently produce corrupted tensor output when the input GGUF file is truncated. Fix : add short-read checks in gguf-split.cpp (in copy_file_to_file in split_strategy) and export-lora.cpp (in read_tensor_data of file_input) so that truncated input is rejected.

GGUF split Example

CLI to split / merge GGUF files.

Command line options:

  • --split: split GGUF to multiple GGUF, default operation.
  • --split-max-size: max size per split in M or G, f.ex. 500M or 2G.
  • --split-max-tensors: maximum tensors in each split: default(128)
  • --merge: merge multiple GGUF to a single GGUF. You only need to specify the name of the first GGUF to merge, the name of the merged GGUF, and the CLI will find the other GGUFs it needs within the same folder.
