-Subject: [PATCH] x86, x32: Correct invalid use of user timespec in the kernel
-
-The x32 case for the recvmsg() timout handling is broken:
-
-  asmlinkage long compat_sys_recvmmsg(int fd, struct compat_mmsghdr __user *mmsg,
-                                      unsigned int vlen, unsigned int flags,
-                                      struct compat_timespec __user *timeout)
-  {
-          int datagrams;
-          struct timespec ktspec;
-
-          if (flags & MSG_CMSG_COMPAT)
-                  return -EINVAL;
-
-          if (COMPAT_USE_64BIT_TIME)
-                  return __sys_recvmmsg(fd, (struct mmsghdr __user *)mmsg, vlen,
-                                        flags | MSG_CMSG_COMPAT,
-                                        (struct timespec *) timeout);
-          ...
-
-The timeout pointer parameter is provided by userland (hence the __user
-annotation) but for x32 syscalls it's simply cast to a kernel pointer
-and is passed to __sys_recvmmsg which will eventually directly
-dereference it for both reading and writing.  Other callers to
-__sys_recvmmsg properly copy from userland to the kernel first.
-
-The bug was introduced by commit ee4fa23c4bfc ("compat: Use
-COMPAT_USE_64BIT_TIME in net/compat.c") and should affect all kernels
-since 3.4 (and perhaps vendor kernels if they backported x32 support
-along with this code).
-
-Note that CONFIG_X86_X32_ABI gets enabled at build time and only if
-CONFIG_X86_X32 is enabled and ld can build x32 executables.
-
-Other uses of COMPAT_USE_64BIT_TIME seem fine.
-
-This addresses CVE-2014-0038.
