Fixes: RIPD-1574
Alias beast address classes to the asio equivalents. Adjust users of
address classes accordingly. Fix resolver class so that it can support
ipv6 addresses. Make unit tests use ipv6 localhost network. Extend
endpoint peer message to support string endpoint
representations while also supporting the existing fields (both are
optional/repeated types). Expand test for Livecache and Endpoint.
Workaround some false positive ipaddr tests on windows (asio bug?)
Replaced usage of address::from_string(deprecated) with free function
make_address. Identified a remaining use of v4 address type and
replaced with the more appropriate IPEndpoint type (rpc_ip cmdline
option). Add CLI flag for using ipv4 with unit tests.
Release Notes
-------------
The optional rpc_port command line flag is deprecated. The rpc_ip
parameter now works as documented and accepts ip and port combined.
* The compiler can provide many non-explicit constructors for
aggregate types. This is sometimes desired, but it can
happen accidentally, resulting in run-time errors.
* This commit assures that no types are aggregates unless existing
code is using aggregate initialization.
Make sure statically-configured bootcache entries have at least
a reasonable minimum priority. This provides additional protection
against Sybil attacks.
Show the bootcache in the ouput of the print command.
Replace Journal public data members with member function accessors
in order to make Journal lighter weight. The change makes a
Journal cheaper to pass by value.
Also add missing stream checks (e.g., calls to JLOG) to avoid
text processing that ultimately will not be stored in the log.
The Journal API is affected. There are two uses for the
Journal::Severity enum:
o It is used to declare a threshold which log messages must meet
in order to be logged.
o It declares the current logging level which will be compared
to the threshold.
Those uses that affect the threshold are now named threshold()
rather than severity() to make the uses easier to distinguish.
Additionally, Journal no longer carries a Severity variable.
All handling of the threshold() is now delegated to the
Journal::Sink.
Sinks are no longer constructed with a default threshold of
kWarning; their threshold must be passed in on construction.
The RippleAddress class was used to represent a number of fundamentally
different types: account public keys, account secret keys, node public
keys, node secret keys, seeds and generators.
The class is replaced by the following types:
* PublicKey for account and node public keys
* SecretKey for account and node private keys
* Generator for generating secp256k1 accounts
* Seed for account, node and generator seeds
* A new, unified interface for generating random numbers and
filling buffers supporting any engine that fits the
UniformRandomNumberGenerator concept;
* Automatically seeded replacement for rand using the fast
xorshift+ PRNG engine;
* A CSPRNG engine that can be used with the new framework
when needing to to generate cryptographically secure
randomness.
* Unit test cleanups to work with new engine.
Multiple servers behind NAT might share a single public IP, making it
difficult for them to connect to the Ripple network since multiple
incoming connections from the same non-private IP are currently not
allowed.
RippleD now automatically allows between 2 and 5 incoming connections,
from the same public IP based on the total number of peers that it is
configured to accept.
Administrators can manually change the limit by adding an "ip_limit"
key value pair in the [overlay] stanza of the configuration file and
specifying a positive non-zero number. For example:
[overlay]
ip_limit=3
The previous "one connection per IP" strategy can be emulated by
setting "ip_limit" to 1.
The implementation imposes both soft and hard upper limits and will
adjust the value so that a single IP cannot consume all inbound slots.
* Remove cxx14 compatibility layer from ripple
* Update travis to clang 3.6 and drop gcc 4.8
* Remove unneeded beast CXX14 defines
* Do not run clang build with gdb with travis
* Update circle ci to clang 3.6 & gcc-5
* Don't run rippled in gdb, clang builds crash gdb
* Staticly link libstdc++, boost, ssl, & protobuf
* Support builds on ubuntu 15.10
* Each peer has a "sane/insane/unknown" status
* Status updated based on peer ledger sequence
* Status reported in peer json
* Only sane peers preferred for historical ledgers
* Overlay endpoints only accepted from known sane peers
* Untrusted proposals not relayed from insane peers
* Untrusted validations not relayed from insane peers
* Transactions from insane peers are not processed
* Periodically drop outbound connections to bad peers
* Bad peers get bootcache valence of zero
Peer "sanity" is based on the ledger sequence number they are on. We
quickly become able to assess this based on current trusted validations.
We quarrantine rogue messages and disconnect bad outbound connections to
help maintain the configured number of good outbound connections.
* Brings the soci subtree into rippled.
* Validator, peerfinder, and SHAMapStore use new soci backend.
* Optional postgresql backend for soci (if POSTGRESQL_ROOT env var is set).
Legacy workarounds for Visual Studio non thread-safe initialization
of function local objects with static storage duration are removed:
* Remove LeakChecked
* Remove StaticObject
* Remove SharedSingleton
This adds support for a cgi /crawl request, issued over HTTPS to the configured
peer protocol port. The response to the request is a JSON object containing
the node public key, type, and IP address of each directly connected neighbor.
The IP address is suppressed unless the neighbor has requested its address
to be revealed by adding "Crawl: public" to its HTTP headers. This field is
currently set by the peer_private option in the rippled.cfg file.
