So, in struct compat_msgbuf, replace the one-element array with a flexible-array member. This fixes warnings such as: ./ipc/msg.c:981:6-11: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays) Signed-off-by: Atul Raut --- ipc/msg.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/ipc/msg.c b/ipc/msg.c index fd08b3cb36d7..ee6af4fe52bf 100644 --- a/ipc/msg.c +++ b/ipc/msg.c @@ -978,7 +978,7 @@ SYSCALL_DEFINE4(msgsnd, int, msqid, struct msgbuf __user *, msgp, size_t, msgsz, struct compat_msgbuf { compat_long_t mtype; - char mtext[1]; + char mtext[]; }; long compat_ksys_msgsnd(int msqid, compat_uptr_t msgp, -- 2.34.1
