None of the changes are bug fixes (they only change behavior for corrupted asmap files), but they may make things easier to follow. In a second step, a sanity checker is added that effectively executes every potential code path through the asmap file, checking the same failure cases as the interpreter, and more. It takes around 30 ms to run for me for a 1.2 MB asmap file. I've verified that this accepts asmap files constructed by https://github.com/sipa/asmap/blob/master/buildmap.py with a large dataset, and no longer accepts it with 1 bit changed in it.

2020-05-06Merge #18806: net: remove is{Empty,Full} flags from CBloomFilter, clarify ↵fanquake
CVE fix 1ad8ea2b73134bdd8d6b50704a019d47ad2191d8 net: remove is{Empty,Full} flags from CBloomFilter, clarify CVE fix (Sebastian Falbesoner) Pull request description: The BIP37 bloom filter class `CBloomFilter` contains two flags `isEmpty`/`isFull` together with an update method with the purpose to, according to the comments, "avoid wasting cpu", i.e. the mechanism should serve as an optimization for the trivial cases of empty (all bits zero) or full (all bits one) filters. However, the real reason of adding those flags (introduced with commit https://github.com/bitcoin/bitcoin/commit/37c6389c5a0ca63ae3573440ecdfe95d28ad8f07 by gmaxwell) was a _covert fix_ of [CVE-2013-5700](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-5700), a vulnerability that allowed a divide-by-zero remote node crash. According to gmaxwell himself (https://github.com/bitcoin/bitcoin/pull/9060#issuecomment-257749165): > the IsEmpty/IsFull optimizations were largely a pretextual optimization intended to make unexploitable a remote crash vulnerability (integer division by zero) that existed in the original bloom filtering code without disclosing it. I'm doubtful that they are all that useful. :) For more information on how to trigger this crash, see PR https://github.com/bitcoin/bitcoin/pull/18515 which contains a detailled description and a regression test. It has also been discussed on a [recent PR club meeting on fuzzing](https://bitcoincore.reviews/18521.html). The covert fix code already led to issues and PR based on the wrong assumption that the flags are there for optimization reasons (see #16886 and #16922). This PR gets rid of the flags and the update method and just focuses on the CVE fix itself, i.e. it can be seen as a revert of the covert fix commit modulo the actual fix.

Instead of AddToWallet taking a temporary CWalletTx object and then potentially merging it with a pre-existing CWalletTx, have it take a callback so callers can update the pre-existing CWalletTx directly. This makes AddToWallet simpler because now it is only has to be concerned with saving CWalletTx objects and not merging them. This makes AddToWallet calls clearer because they can now make direct updates to CWalletTx entries without having to make temporary objects and then worry about how they will be merged. Motivation for this change came from the bumpfee PR #8456 where we wanted to be able to call AddToWallet to make a simple update to an existing transaction, but were reluctant to, because the existing CWalletTx merging logic did not apply and seemed dangerous try to update as part of that PR. After this refactoring, the bumpfee PR could call AddToWallet safely instead of implementing a duplicate AddToWallet function. This also allows getting rid of the CWalletTx copy constructor to prevent unintentional copying.

Make sure no `DescriptorScriptPubKeyMan` or `WalletDescriptor` members are left uninitialized after construction.

Speaking to Cory he clarified that the intention was to "require only vanilla c++11 and turn _off_ extension support so they would fail to compile". However in the codebase we are currently making use of some GNU extensions. We should either remove there usage, or at least amend our CXX compiler checks. I'd prefer the former. #### anonymous structs ```bash ./prevector.h:153:9: warning: anonymous structs are a GNU extension [-Wgnu-anonymous-struct] struct { ``` This is fixed in https://github.com/bitcoin/bitcoin/commit/b849212c1ec01cc8633b8cdcd390da9b1051be0d. #### variadic macros ```bash ./undo.h:57:50: warning: must specify at least one argument for '...' parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments] ::Unserialize(s, VARINT(nVersionDummy)); ``` This is taken care of in #18087. The `LOG_TIME_*` macros introduced in #16805 make use of a [GNU extension](https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html). ```bash In file included from validation.cpp:22: ./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments] BCLog::Timer<std::chrono::milliseconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__) ^ ./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments] ./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments] ./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments] ./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments] ./logging/timer.h:101:92: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments] BCLog::Timer<std::chrono::seconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__) ^ 6 warnings generated. ``` This is fixed in 081a0ab64eb442bc85c4d4a4d3bc2c8e97ac2a6d and 612e8e138b97fc5ad2f38847300132a8fc423c3f. #### prevention To ensure that usage doesn't creep back in we can add [`-Wgnu`](https://clang.llvm.org/docs/DiagnosticsReference.html#wgnu) to our compile time flags, which will make Clang warn whenever it encounters GNU extensions. This would close #14130. Also related to #17230, where it's suggested we use a GNU extension, the `gnu::pure` attribute.

Proof of concept output: ``` coins.cpp:243:17: runtime error: signed integer overflow: 9223200000000000000 + 2100000000000000 cannot be represented in type 'long' GetValueIn = -9221444073709551616 ``` Proof of concept code: ```c++ CMutableTransaction mutable_transaction; mutable_transaction.vin.resize(4393); Coin coin; coin.out.nValue = MAX_MONEY; assert(MoneyRange(coin.out.nValue)); CCoinsCacheEntry coins_cache_entry; coins_cache_entry.coin = coin; coins_cache_entry.flags = CCoinsCacheEntry::DIRTY; CCoinsView backend_coins_view; CCoinsViewCache coins_view_cache{&backend_coins_view}; CCoinsMap coins_map; coins_map.emplace(COutPoint{}, std::move(coins_cache_entry)); coins_view_cache.BatchWrite(coins_map, {}); const CAmount total_value_in = coins_view_cache.GetValueIn(CTransaction{mutable_transaction}); std::cout << "GetValueIn = " << total_value_in << std::endl; ``` ACKs for top commit: MarcoFalke: ACK b56607a89ba112083f2b0a7b64ab18d66b26e2be promag: Code review ACK b56607a89ba112083f2b0a7b64ab18d66b26e2be. jb55: ACK b56607a89ba112083f2b0a7b64ab18d66b26e2be hebasto: ACK b56607a89ba112083f2b0a7b64ab18d66b26e2be, I have not tested the code, but I have reviewed it and it looks OK, I agree it can be merged.

Enable -Wconditional-uninitialized to warn on potentially uninitialized reads. Fix the sole such warning in Bitcoin Core in GetRdRand(): r1 would be set to 0 on rdrand failure, so initializing it to 0 is a non-functional change. From "Intel 64 and IA-32 ArchitecturesSoftware Developer's Manual" [1], page 1711: "CF=1 indicates that the data in the destination is valid. Otherwise CF=0 and the data in the destination operand will be returned as zeros for the specified width."

Currently, because the node's `cs_main` mutex is always locked before the wallet's `cs_wallet` mutex (to prevent deadlocks), `cs_main` currently stays locked while the wallet does relatively slow things like creating and listing transactions. Switching the lock order so `cs_main` is acquired after `cs_wallet` allows `cs_main` to be only locked intermittently while the wallet is doing slow operations, so the node is not blocked waiting for the wallet. To review the present PR, most of getting right the move is ensuring any `LockAssertion` in `Chain::Lock` method is amended as a `LOCK(cs_main)`. And in final commit, check that any wallet code which was previously locking the chain is now calling a method, enforcing the lock taking job. So far the only exception I found is `handleNotifications`, which should be corrected.

2020-05-01Remove CWalletTx merging logic from AddToWalletRussell Yanofsky
Instead of AddToWallet taking a temporary CWalletTx object and then potentially merging it with a pre-existing CWalletTx, have it take a callback so callers can update the pre-existing CWalletTx directly. This makes AddToWallet simpler because now it is only has to be concerned with saving CWalletTx objects and not merging them. This makes AddToWallet calls clearer because they can now make direct updates to CWalletTx entries without having to make temporary objects and then worry about how they will be merged. This is a pure refactoring, no behavior is changing.
2020-04-30[wallet] Remove locked_chain from CWallet, its RPCs and testsAntoine Riard

Currently because the node's cs_main mutex is always locked before the wallet's cs_wallet mutex (to prevent deadlocks), cs_main currently stays locked while the wallet does relatively slow things like creating and listing transactions. This commit only remmove chain lock tacking in wallet code, and invert lock order from cs_main, cs_wallet to cs_wallet, cs_main. must happen at once to avoid any deadlock. Previous commit were only removing Chain::Lock methods to Chain interface and enforcing they take cs_main. Remove LockChain method from CWallet and Chain::Lock interface.
