2022-08-03cuckoocache: Check for uint32 overflow in setup_bytesCarl Dong
This fixes an potential overflow which existed prior to this patchset. If CuckooCache::cache<Element, Hash>::setup_bytes is called with a `size_t bytes` which, when divided by sizeof(Element), does not fit into an uint32_t, the implicit conversion to uint32_t in the call to setup will result in an overflow. At least on x86_64, this overflow is possible: static_assert(std::numeric_limits<size_t>::max() / 32 <= std::numeric_limits<uint32_t>::max()); static_assert(std::numeric_limits<size_t>::max() / 4 <= std::numeric_limits<uint32_t>::max()); This commit detects such cases and signals to callers that the `size_t bytes` input is too large.
2022-08-03cuckoocache: Return approximate memory sizeCarl Dong
Returning the approximate total size eliminates the need for InitS*Cache() to do nElems*sizeof(uint256). The cuckoocache has a better idea of this information.

A few "a->an" and "an->a". "Shows, if the supplied default SOCKS5 proxy" -> "Shows if the supplied default SOCKS5 proxy". Change made on 3 occurrences. "without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command". Removed duplicate words such as "the the".
2017-06-12Add an explanation of quickly hashing onto a non-power of two range.Gregory Maxwell
In Olaoluwa Osuntokun's recent protocol proposal they were using a mod in an inner loop. I wanted to suggest a normative protocol change to use the trick we use here, but to find an explanation of it I had to dig up the PR on github. After I posted about it several other developers commented that it was very interesting and they were unaware of it. I think ideally the code should be self documenting and help educate other contributors about non-obvious techniques that we use. So I've written a description of the technique with citations for future reference.
