eCryptfs: Infinite loop due to overflow in ecryptfs_write()
commit 684a3ff7e69acc7c678d1a1394fe9e757993fd34 upstream.
ecryptfs_write() can enter an infinite loop when truncating a file to a
size larger than 4G. This only happens on architectures where size_t is
represented by 32 bits.
This was caused by a size_t overflow due to it incorrectly being used to
store the result of a calculation which uses potentially large values of
type loff_t.
