2011-08-31Fix rpc-hanging deadlocksGavin Andresen
Collapsed multiple wallet mutexes to a single cs_wallet, to avoid deadlocks with wallet methods that acquired locks in different order. Also change master RPC call handler to acquire cs_main and cs_wallet locks before executing RPC calls; requiring each RPC call to acquire the right set of locks in the right order was too error-prone.

2011-08-19Make some global variables less-global (static)Giel van Schijndel
Explicitly make these global variables less-global to reduce the maximum scope of this global state. In my experience global variables tend to be a major source of bugs. As such the less accessible they are the less likely they are to be the source of a bug. Signed-off-by: Giel van Schijndel <me@mortis.eu>

Use 'unsigned char' rather than 'char' for pchMessageStart.
2011-08-10Use 'unsigned char' rather than 'char' for pchMessageStart.Venkatesh Srinivas
Regarding https://bitcointalk.org/index.php?topic=28022.0 main.cpp has: "char pchMessageStart[4] = { 0xf9, 0xbe, 0xb4, 0xd9 };" Per discussion on the thread linked, leaving the signedness of pchMessageStart is unsafe for values > 0x80. This patch specifies 'unsigned char' in main.cpp and net.h. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2011-07-21Actually use mapAlreadyAskedFor.Matt Corallo
Previously, mapAlreadyAskedFor was read from, but never added to. The original intent was to use mapAlreadyAskedFor to keep track of the time an item was requested and "Each retry is 2 minutes after the last". This implements that intent.

2011-07-13fix warnings: expression result unused [-Wunused-value]Giel van Schijndel
In the assert()s take advantage of the fact that string constants ("string") are effectively of type 'const char []', which when used in an expression yield a non-NULL pointer. An assertion that should always fail can thus be formulated as: assert(!"fail); An assertion where a text message should be added to the expression can be written as such: assert("message" && expression); Signed-off-by: Giel van Schijndel <me@mortis.eu>
2011-07-13Make an invalid addrIncoming so that old clients crash.Matt Corallo
This prevents old clients from opening, and thus corrupting or otherwise causing harm to encrypted wallets.
2011-07-13Add wallet privkey encryption.Matt Corallo
This commit adds support for ckeys, or enCrypted private keys, to the wallet. All keys are stored in memory in their encrypted form and thus the passphrase is required from the user to spend coins, or to create new addresses. Keys are encrypted with AES-256-CBC using OpenSSL's EVP library. The key is calculated via EVP_BytesToKey using SHA512 with (by default) 25000 rounds and a random salt. By default, the user's wallet remains unencrypted until they call the RPC command encryptwallet <passphrase> or, from the GUI menu, Options-> Encrypt Wallet. When the user is attempting to call RPC functions which require the password to unlock the wallet, an error will be returned unless they call walletpassphrase <passphrase> <time to keep key in memory> first. A keypoolrefill command has been added which tops up the users keypool (requiring the passphrase via walletpassphrase first). keypoolsize has been added to the output of getinfo to show the user the number of keys left before they need to specify their passphrase (and call keypoolrefill). Note that walletpassphrase will automatically fill keypool in a separate thread which it spawns when the passphrase is set. This could cause some delays in other threads waiting for locks on the wallet passphrase, including one which could cause the passphrase to be stored longer than expected, however it will not allow the passphrase to be used longer than expected as ThreadCleanWalletPassphrase will attempt to get a lock on the key as soon as the specified lock time has arrived. When the keypool runs out (and wallet is locked) GetOrReuseKeyFromPool returns vchDefaultKey, meaning miners may start to generate many blocks to vchDefaultKey instead of a new key each time. A walletpassphrasechange <oldpassphrase> <newpassphrase> has been added to allow the user to change their password via RPC. Whenever keying material (unencrypted private keys, the user's passphrase, the wallet's AES key) is stored unencrypted in memory, any reasonable attempt is made to mlock/VirtualLock that memory before storing the keying material. This is not true in several (commented) cases where mlock/VirtualLocking the memory is not possible. Although encryption of private keys in memory can be very useful on desktop systems (as some small amount of protection against stupid viruses), on an RPC server, the password is entered fairly insecurely. Thus, the only main advantage encryption has for RPC servers is for RPC servers that do not spend coins, except in rare cases, eg. a webserver of a merchant which only receives payment except for cases of manual intervention. Thanks to jgarzik for the original patch and sipa, gmaxwell and many others for all their input. Conflicts: src/wallet.cpp

2011-06-15CWallet classPieter Wuille
* A new class CKeyStore manages private keys, and script.cpp depends on access to CKeyStore. * A new class CWallet extends CKeyStore, and contains all former wallet-specific globals; CWallet depends on script.cpp, not the other way around. * Wallet-specific functions in CTransaction/CTxIn/CTxOut (GetDebit, GetCredit, GetChange, IsMine, IsFromMe), are moved to CWallet, taking their former 'this' argument as an explicit parameter * CWalletTx objects know which CWallet they belong to, for convenience, so they have their own direct (and caching) GetDebit/... functions. * Some code was moved from CWalletDB to CWallet, such as handling of reserve keys. * Main.cpp keeps a set of all 'registered' wallets, which should be informed about updates to the block chain, and does not have any notion about any 'main' wallet. Function in main.cpp that require a wallet (such as GenerateCoins), take an explicit CWallet* argument. * The actual CWallet instance used by the application is defined in init.cpp as "CWallet* pwalletMain". rpc.cpp and ui.cpp use this variable. * Functions in main.cpp and db.cpp that are not used by other modules are marked static. * The code for handling the 'submitorder' message is removed, as it not really compatible with the idea that a node is independent from the wallet(s) connected to it, and obsolete anyway.
2011-06-15move wallet code to separate filePieter Wuille
This introduces two new source files, keystore.cpp and wallet.cpp with corresponding headers. Code is moved from main and db, in a preparation for a follow-up commit which introduces the classes CWallet and CKeyStore.
