2015-03-23Always use a 50% chance to choose between tried and new entriesPieter Wuille
This change was suggested as Countermeasure 2 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015.
2015-03-23Do not bias outgoing connections towards fresh addressesPieter Wuille

2015-03-23Simplify hashing codePieter Wuille
2015-03-23Make addrman's bucket placement deterministic.Pieter Wuille
Give each address a single fixed location in the new and tried tables, which become simple fixed-size arrays instead of sets and vectors. This prevents attackers from having an advantages by inserting an address multiple times. This change was suggested as Countermeasure 1 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015. It is also more efficient.

Also correct the file license

serialization now has no dependencies.
2014-09-19Apply clang-format on some infrequently-updated filesPieter Wuille
2014-09-05Improve readability of CAddrInfo::IsTerribleTeran McKinney
- Replaced 86400 with 24*60*60 - Remove references to specific timespans in comments Github-Pull: #4724
2014-08-18addrman: Do not propagate obviously poor addresses onto the networkJeff Garzik
2014-01-23Remove redundant .c_str()sWladimir J. van der Laan
After the tinyformat switch sprintf() family functions support passing actual std::string objects. Remove unnecessary c_str calls (236 of them) in logging and formatting.
2013-12-25Changed Get64(.) to GetLow64()Thomas Holenstein
The function Get64(.) has a bug in case the width is not divisible by 64. Since it is only ever used as Get64(0) this simply changes it to this special case. Additionally, an assert is added, and a cast to prevent a compiler error.
2013-11-10Cleanup code using forward declarations.Brandon Dahler
Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

2012-12-18Split off hash.h from util.hPieter Wuille

2012-05-18Update License in File HeadersFordy
I originally created a pull to replace the "COPYING" in crypter.cpp and crypter.h, but it turned out that COPYING was actually the correct file.
2012-05-09Clean up warningsPieter Wuille
* Use -Wall -Wextra -Wformat -Wformat-security -Wno-unused-parameters * Remove xCXXFLAGS usage in makefile.unix * Fix several recent and older sign-compare warnings
2012-05-05Fix addrman crashesPieter Wuille
A function returned the element to remove from a bucket, instead of its position in that bucket. This function was only called when a tried bucket overflowed, which only happens after many outgoing connections have been made. Closes: #1065, #1156
2012-05-05Add extra asserts to addrmanPieter Wuille
2012-04-17Further reduce header dependenciesPieter Wuille
This commit removes the dependency of serialize.h on PROTOCOL_VERSION, and makes this parameter required instead of implicit. This is much saner, as it makes the places where changing a version number can have an influence obvious.
2012-04-15Fix loop index var types, fixing many minor sign comparison warningsJeff Garzik
foo.size() typically returns an unsigned integral type; make loop variables match those types' signedness.
2012-04-15fix warnings: '&&' within '||' [-Wlogical-op-parentheses]Wladimir J. van der Laan
2012-02-24CAddrMan: stochastic address managerPieter Wuille
Design goals: * Only keep a limited number of addresses around, so that addr.dat does not grow without bound. * Keep the address tables in-memory, and occasionally write the table to addr.dat. * Make sure no (localized) attacker can fill the entire table with his nodes/addresses. See comments in addrman.h for more detailed information.
