Baruch Siach 7343178ccf bpf: fix uapi bpf_prog_info fields alignment ... [ Upstream commit 0472301a28f6cf53a6bc5783e48a2d0bbff4682f ] Merge commit 1c8c5a9d38 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next") undid the fix from commit 36f9814a49 ("bpf: fix uapi hole for 32 bit compat applications") by taking the gpl_compatible 1-bit field definition from commit b85fab0e67 ("bpf: Add gpl_compatible flag to struct bpf_prog_info") as is. That breaks architectures with 16-bit alignment like m68k. Add 31-bit pad after gpl_compatible to restore alignment of following fields. Thanks to Dmitry V. Levin his analysis of this bug history.
