net: ipv4: Convert IP network timestamps to be y2038 safe
[ Upstream commit 822c868532cae2cc1c51f4f18ab61c194d98aaf6 ]
ICMP timestamp messages and IP source route options require
timestamps to be in milliseconds modulo 24 hours from
midnight UT format.
Add inet_current_timestamp() function to support this. The function
returns the required timestamp in network byte order.
Timestamp calculation is also changed to call ktime_get_real_ts64()
which uses struct timespec64. struct timespec64 is y2038 safe.
Previously it called getnstimeofday() which uses struct timespec.
struct timespec is not y2038 safe.
