  "message": "UPSTREAM: bpf: Fix integer overflow in argument calculation for bpf_map_area_alloc\n\ncommit 7dd5d437c258bbf4cc15b35229e5208b87b8b4e0 upstream.\n\nIn 32-bit architecture, the result of sizeof() is a 32-bit integer so\nthe expression becomes the multiplication between 2 32-bit integer which\ncan potentially leads to integer overflow. As a result,\nbpf_map_area_alloc() allocates less memory than needed.\n\nFix this by casting 1 operand to u64.\n\nFixes: 0d2c4f964050 (\"bpf: Eliminate rlimit-based memory accounting for sockmap and sockhash maps\")\nFixes: 99c51064fb06 (\"devmap: Use bpf_map_area_alloc() for allocating hash buckets\")\nFixes: 546ac1ffb70d (\"bpf: add devmap, a map for storing net device references\")\nSigned-off-by: Bui Quang Minh \u003cminhquangbui99@gmail.com\u003e\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\nLink: https://lore.kernel.org/bpf/20210613143440.71975-1-minhquangbui99@gmail.com\nSigned-off-by: Connor O\u0027Brien \u003cconnoro@google.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nSigned-off-by: Lee Jones \u003clee.jones@linaro.org\u003e\nChange-Id: I9ce1991224a87eb39acf1da4923534e22380fc42\n",
