Arnd Bergmann 56af94aace samples: user-trap: fix strict-aliasing warning ... I started getting warnings for this one file, though I can't see what changed since it was originally introduced in commit fec7b66905 ("samples: add an example of seccomp user trap"). samples/seccomp/user-trap.c: In function 'send_fd': samples/seccomp/user-trap.c:50:11: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] 50 | *((int *)CMSG_DATA(cmsg)) = fd; | ~^~~~~~~~~~~~~~~~~~~~~~~ samples/seccomp/user-trap.c: In function 'recv_fd': samples/seccomp/user-trap.c:83:18: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] 83 | return *((int *)CMSG_DATA(cmsg)); | ~^~~~~~~~~~~~~~~~~~~~~~~ Using a temporary pointer variable avoids the warning.
