* | Apply BIP30 checks to all blocks except the two historic violations.Gregory Maxwell2012-09-091-3/+6
|/ | | | | | | | | Matt pointed out some time ago that there existed a minor DOS attack where a node in its initial block download could be wedged by an overwrite attack in a fork created between checkpoints before a time where BIP30 was enforced. Now that the BIP30 timestamp is irreversibly past the check can be more aggressive and apply to all blocks except the two historic violations.

| * | Useless vector declarationxanatos2012-09-031-1/+0

* Special-case the last alert for alert-key-compromised caseGavin Andresen2012-08-271-0/+22
| | | | | | | | | | Hard-code a special nId=max int alert, to be broadcast if the alert key is ever compromised. It applies to all versions, never expires, cancels all previous alerts, and has a fixed message: URGENT: Alert key compromised, upgrade required Variations are not allowed (ignored), so an attacker with the private key cannot broadcast empty-message nId=max alerts.
* Alert system DoS preventionGavin Andresen2012-08-261-6/+19
| | | | | | | | | | | This fixes two alert system vulnerabilities found by Sergio Lerner; you could send peers unlimited numbers of invalid alert message to try to either fill up their debug.log with messages and/or keep their CPU busy checking signatures. Fixed by disconnecting/banning peers if they send 10 or more bad (invalid/expired/cancelled) alerts.

* Reject block.nVersion<=1 blocks if network has upgraded to version=2Gavin Andresen2012-08-201-1/+10
| | | | | | | | | | | If 950 of the last 1,000 blocks are nVersion=2, reject nVersion=1 (or zero, but no bitcoin release has created block.nVersion=0) blocks -- 75 of last 100 on testnet3. This rule is being put in place now so that we don't have to go through another "express support" process to get what we really want, which is for every single new block to include the block height in the coinbase.
* Block height in coinbase as a new block ruleGavin Andresen2012-08-201-1/+27
| | | | | | | | | | | "Version 2" blocks are blocks that have nVersion=2 and have the block height as the first item in their coinbase. Block-height-in-the-coinbase is strictly enforced when version=2 blocks are a supermajority in the block chain (750 of the last 1,000 blocks on main net, 51 of 100 for testnet). This does not affect old clients/miners at all, which will continue producing nVersion=1 blocks, and which will continue to be valid.

* / | Update Warning-strings to use a standard-formatPhilip Kaufmann2012-08-011-4/+4
|/ / | | | | | | | | | | | | | | | | - ensure warnings always start with "Warning:" and that the first character after ":" is written uppercase - ensure the first sentence in warnings ends with an "!" - remove unneeded spaces from Warning-strings - add missing Warning-string translation - remove a "\n" and replace with untranslatable "<br><br>"
* | Switch testnet3's message bytes to avoid connecting to old nodes.Gregory Maxwell2012-07-261-4/+4
| | | | | | | | | | | | | | | | The new bytes are based on "11" to appeal to Gavin's 11 fetish. This breaks existing testnet3 nodes as the blockchain files are also versioned. To upgrade a node delete everything except wallet.dat from your .bitcoin/testnet3 folder.

* | When creating new blocks, sort 'paid' area by fee-per-kbGavin Andresen2012-07-261-31/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | Modify CreateNewBlock so that instead of processing all transactions in priority order, process the first 27K of transactions in priority order and then process the rest in fee-per-kilobyte order. This is the first, minimal step towards better a better fee-handling system for both miners and end-users; this patch should be easy to backport to the old versions of Bitcoin, and accomplishes the most important goal-- allow users to "buy their way in" to blocks using transaction fees.
