Deepa Dinamani <deepa.kernel@gmail.com> writes: > SO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval > as the time format. struct timeval is not y2038 safe. > The subsequent patches in the series add support for new socket > timeout options with _NEW suffix that will use y2038 safe > data structures. Although the existing struct timeval layout > is sufficiently wide to represent timeouts, because of the way > libc will interpret time_t based on user defined flag, these > new flags provide a way of having a structure that is the same > for all architectures consistently. > Rename the existing options with _OLD suffix forms so that the > right option is enabled for userspace applications according > to the architecture and time_t definition of libc. > > Signed-off-by: Deepa Dinamani <deepa.kernel@gmail.com> > Acked-by: Willem de Bruijn <willemb@google.com> > Cc: ccaulfie@redhat.com > Cc: deller@gmx.de > Cc: paulus@samba.org > Cc: ralf@linux-mips.org > Cc: rth@twiddle.net > Cc: cluster-devel@redhat.com > Cc: linuxppc-dev@lists.ozlabs.org > Cc: linux-alpha@vger.kernel.org > Cc: linux-arch@vger.kernel.org > Cc: linux-mips@vger.kernel.org > Cc: linux-parisc@vger.kernel.org > Cc: sparclinux@vger.kernel.org > --- > arch/alpha/include/uapi/asm/socket.h | 7 +++++-- > arch/mips/include/uapi/asm/socket.h | 6 ++++-- > arch/parisc/include/uapi/asm/socket.h | 6 ++++-- > arch/powerpc/include/uapi/asm/socket.h | 4 ++-- The powerpc changes look OK to me.
