The codepaths that read "chunk" formatted files have been corrected to pay attention to the chunk size and notice broken files. * jk/chunk-bounds: (21 commits) t5319: make corrupted large-offset test more robust chunk-format: drop pair_chunk_unsafe() commit-graph: detect out-of-order BIDX offsets commit-graph: check bounds when accessing BIDX chunk commit-graph: check bounds when accessing BDAT chunk commit-graph: bounds-check generation overflow chunk commit-graph: check size of generations chunk commit-graph: bounds-check base graphs chunk commit-graph: detect out-of-bounds extra-edges pointers commit-graph: check size of commit data chunk midx: check size of revindex chunk midx: bounds-check large offset chunk midx: check size of object offset chunk midx: enforce chunk alignment on reading midx: check size of pack names chunk commit-graph: check consistency of fanout table midx: check size of oid lookup chunk commit-graph: check size of oid fanout chunk midx: stop ignoring malformed oid fanout chunk t: add library for munging chunk-format files ...
