NET: random : secure_tcp_sequence_number should not assume CONFIG_KTIME_SCALAR
[NET] random : secure_tcp_sequence_number should not assume CONFIG_KTIME_SCALAR
[ Upstream commit: 6dd10a62353a50b30b30e0c18653650975b29c71 ]
All 32 bits machines but i386 dont have CONFIG_KTIME_SCALAR. On these
machines, ktime.tv64 is more than 4 times the (correct) result given
by ktime_to_ns()
Again on these machines, using ktime_get_real().tv64 >> 6 give a
32bits rollover every 64 seconds, which is not wanted (less than the
120 s MSL)
Using ktime_to_ns() is the portable way to get nsecs from a ktime, and
have correct code.
