Jesper Dangaard Brouer d800bad67d bpf: Fix too large copy from user in bpf_test_init ... Commit bc56c919fc ("bpf: Add xdp.frame_sz in bpf_prog_test_run_xdp().") recently changed bpf_prog_test_run_xdp() to use larger frames for XDP in order to test tail growing frames (via bpf_xdp_adjust_tail) and to have memory backing frame better resemble drivers. The commit contains a bug, as it tries to copy the max data size from userspace, instead of the size provided by userspace. This cause XDP unit tests to fail sporadically with EFAULT, an unfortunate behavior. The fix is to only copy the size specified by userspace.
