- Description needed
+ 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
+ impact is a sort of arbitrary kernel write-where-what primitive by
+ unprivileged users where the to-be-written area must contain valid
+ timespec data initially (the first 64 bit long field must be positive
+ and the second one must be < 1G).
