Friedrich Vock 1bdd4ae98b bpf: Fix potential integer overflow in resolve_btfids ... [ Upstream commit 44382b3ed6 ] err is a 32-bit integer, but elf_update returns an off_t, which is 64-bit at least on 64-bit platforms. If symbols_patch is called on a binary between 2-4GB in size, the result will be negative when cast to a 32-bit integer, which the code assumes means an error occurred. This can wrongly trigger build failures when building very large kernel images.
