Merge bitcoin/bitcoin#23970: Remove pointless and confusing shift in RelayAddress
fa9f4554ca5e64e7960b74dd0ad8fb1cd7c2f091 refactor: Remove pointless and confusing shift in RelayAddress (MarcoFalke)
Pull request description:
The second argument written to the siphash is already quantized to 24 hours, so it seems confusing to quantize the first argument to 32 bits (out of 64 bits).
> The shifting is pointless, we should get rid of it. It seems to be a silly evolution of this 2010 Satoshi code: 5cbf753 (where it made sense because everything was XORed together, and the address used the high bits, while the time used the low ones).
(Copied from https://github.com/bitcoin/bitcoin/pull/18642#issuecomment-613773120)
(The original code was `uint256 hashRand = hashSalt ^ (((int64)addr.ip)<<32) ^ ((GetTime()+addr.ip)/(24*60*60));`)
This also allows to remove a integer sanitizer suppression for the whole file.
