2020-09-21net: recognize TORv3/I2P/CJDNS networksVasil Dimov
Recognizing addresses from those networks allows us to accept and gossip them, even though we don't know how to connect to them (yet). Co-authored-by: eriknylund <erik@daychanged.com>

2020-08-25Merge #19628: net: change CNetAddr::ip to have flexible sizeMarcoFalke
102867c587f5f7954232fb8ed8e85cda78bb4d32 net: change CNetAddr::ip to have flexible size (Vasil Dimov) 1ea57ad67406b3aaaef5254bc2fa7e4134f3a6df net: don't accept non-left-contiguous netmasks (Vasil Dimov) Pull request description: (chopped off from #19031 to ease review) Before this change `CNetAddr::ip` was a fixed-size array of 16 bytes, not being able to store larger addresses (e.g. TORv3) and encoded smaller ones as 16-byte IPv6 addresses. Change its type to `prevector`, so that it can hold larger addresses and do not disguise non-IPv6 addresses as IPv6. So the IPv4 address `1.2.3.4` is now encoded as `01020304` instead of `00000000000000000000FFFF01020304`. Rename `CNetAddr::ip` to `CNetAddr::m_addr` because it is not an "IP" or "IP address" (TOR addresses are not IP addresses). In order to preserve backward compatibility with serialization (where e.g. `1.2.3.4` is serialized as `00000000000000000000FFFF01020304`) introduce `CNetAddr` dedicated legacy serialize/unserialize methods. Adjust `CSubNet` accordingly. Still use `CSubNet::netmask[]` of fixed 16 bytes, but use the first 4 for IPv4 (not the last 4). Do not accept invalid netmasks that have 0-bits followed by 1-bits and only allow subnetting for IPv4 and IPv6.

2019-10-28Fix occurences of c_str() used with size() to data()Wladimir J. van der Laan
Using `data()` better communicates the intent here. Also, depending on how `c_str()` is implemented, this fixes undefined behavior: The part of the string after the first NULL character might have undefined contents.
2019-08-08util: refactor upper/lowercase functionsKarl-Johan Alm
This includes renaming Downcase() to ToLower() and make it return a string rather than modify referenced arg. Also adds ToUpper() string version.
2019-02-14Add WriteHDKeypath function and move *HDKeypath to util/bip32.{h,cpp}Andrew Chow
Creates new files util/bip32.h and util/bip32.cpp for containing BIP 32 stuff. Moves FormatKeyPath from descriptor.cpp to util/bip32. Adds a wrapper around it to prepent the 'm' for when just the BIP 32 style keypath is needed.
2019-02-11Add pf_invalid arg to std::string DecodeBase{32,64}Glenn Willen
Add support for the optional "pf_invalid" out parameter (which allows the caller to detect decoding failures) to the std::string versions of DecodeBase32 and DecodeBase64. The char* versions already have this feature. Also, rename all uses of pfInvalid to pf_invalid to match style guidelines.
2019-01-10util: Make ToLower and ToUpper take a charWladimir J. van der Laan
Unfortunately, `std::string` elements are (bare) chars. As these are the most likely type to be passed to these functions, make them use char instead of unsigned char. This avoids some casts.
