Xuan Zhuo 340de910d6 xsk: Fix for xp_aligned_validate_desc() when len == chunk_size ... [ Upstream commit ac31565c21937eee9117e43c9cd34f557f6f1cb8 ] When desc->len is equal to chunk_size, it is legal. But when the xp_aligned_validate_desc() got chunk_end from desc->addr + desc->len pointing to the next chunk during the check, it caused the check to fail. This problem was first introduced in bbff2f321a ("xsk: new descriptor addressing scheme"). Later in 2b43470add ("xsk: Introduce AF_XDP buffer allocation API") this piece of code was moved into the new function called xp_aligned_validate_desc(). This function was then moved into xsk_queue.h via 26062b185e ("xsk: Explicitly inline functions and move definitions").
