Now that we require glibc 2.17 or later, we no longer need to check for
different return types in fdelt_chk. It was changed from unsigned long
int to long int in glibc 2.16 . See this commit:
https://sourceware.org/git/?p=glibc.git;a=commit;h=ceb9e56b3d1f8c1922e0526c2e841373843460e2

Pull request description:
This improves/documents the failure cases inside the asmap interpreter. 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.

fa47cf9d95dc2c2822fc96df16f179176935bf96 wallet: Fix typo in assert that is compile-time true (MarcoFalke)
Pull request description:
Commit 92bcd70808b9cac56b184903aa6d37baf9641b37 presumably added a check that a `dest` of type `CNoDestination` implies an empty `scriptChange`.
However, it accidentally checked for `boost::variant::empty`, which always returns false: https://www.boost.org/doc/libs/1_72_0/doc/html/boost/variant.html#id-1_3_46_5_4_1_1_16_2-bb

71f183a49b714a28622277fa668d8f9f3dac0aae build: warn on potentially uninitialized reads (Vasil Dimov)
Pull request description:
* Enable `conditional-uninitialized` warning class to show 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.

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.

2b9cba206594bfbcefcef0c88a0bf793819643bd Remove CWalletTx merging logic from AddToWallet (Russell Yanofsky)
Pull request description:
This is a pure refactoring, no behavior is changing.
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.

ff046aeeba8d4f3ff210d37ba020616c12450ab3 wallet: Make sure no DescriptorScriptPubKeyMan members are uninitialized after construction (practicalswift)
Pull request description:
This is a small folllow-up to #16528 ("Native Descriptor Wallets using DescriptorScriptPubKeyMan") which was merged in to `master` a couple of hours ago.
Make sure no `DescriptorScriptPubKeyMan` or `WalletDescriptor` members are left uninitialized after construction.
Before this change `bool m_internal` was left uninitialized when using the `DescriptorScriptPubKeyMan(WalletStorage&, WalletDescriptor&)` ctor.
The same goes for the now initialized integers which were left uninitialized when using the `WalletDescriptor()` ctor.

5d4999951ee32e333b511245862628e80f83b703 prevector: Avoid unnamed struct, which is a GNU extension (DesWurstes)
Pull request description:
Since we [started using](https://github.com/bitcoin/bitcoin/pull/7165) the `ax_cxx_compile_stdcxx.m4` macro we've been passing `[noext]` to indicate that we don't want to use an extended mode, i.e GNU extensions. 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__)

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.

b56607a89ba112083f2b0a7b64ab18d66b26e2be Remove CCoinsViewCache::GetValueIn(...) (practicalswift)
Pull request description:
Remove `CCoinsViewCache::GetValueIn(...)`.
Fixes #18858.
It seems like `GetValueIn` was added in #748 ("Pay-to-script-hash (OP_EVAL replacement)", merged in 2012) and the last use in validation code was removed in #8498 ("Near-Bugfix: Optimization: Minimize the number of times it is checked that no money...", merged in 2017).
`CCoinsViewCache::GetValueIn(…)` performs money summation like this:
```c++
CAmount CCoinsViewCache::GetValueIn(const CTransaction& tx) const
{
if (tx.IsCoinBase())
return 0;
CAmount nResult = 0;
for (unsigned int i = 0; i < tx.vin.size(); i++)
nResult += AccessCoin(tx.vin[i].prevout).out.nValue;
return nResult;
}
```
Note that no check is done to make sure that the resulting `nResult` is such that it stays within the money bounds (`MoneyRange(nResult)`), or that the summation does not trigger a signed integer overflow.
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;

CCoinsMap coins_map;

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."

2748e8793267126c5b40621d75d1930e358f057e script: prevent UB when computing abs value for num opcode serialize (pierrenn)
Pull request description:
This was reported by practicalswift here #18046
It seems that the original author of the line used a reference to glibc `abs`: https://github.com/lattera/glibc/blob/master/stdlib/abs.c
However depending on some implementation details this can be undefined behavior for unusual values.
A detailed explanation of the UB is provided here : https://stackoverflow.com/questions/17313579/is-there-a-safe-way-to-get-the-unsigned-absolute-value-of-a-signed-integer-with (by [Billy O'Neal](https://twitter.com/malwareminigun))
Simple relevant godbolt example : https://godbolt.org/z/yRwtCG

If the potential translation strings are translated in the future,
trailing whitespace is going to make translation effort harder.
|
|
|
|
Also, mark feebumper bilingual_str as Untranslated
They are technical and have previously not been translated either.
It is questionable whether they can even appear in the GUI.
|
|
Common errors and warnings should be translated when displayed in the
GUI, but not translated when displayed elsewhere. The wallet method
CreateWalletFromFile does not know its caller, so this commit changes it
to return a bilingual_str to the caller.
|
|
CWalletTx initialization has been fixed so it's no longer necessary to change
which wallet a transaction is bound to.

b855592d835bf4b3fb1263b88d4f96669a1722b1 [wallet] Move getHeight from Chain::Lock interface to simple Chain (Antoine Riard)
Pull request description:
This change is intended to make the bitcoin node and its rpc, network and gui interfaces more responsive while the wallet is in use. 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.

Disable copying of CWalletTx objects to prevent bugs where instances get copied
in and out of the mapWallet map and fields are updated in the wrong copy.
|
|
The change in walletdb.cpp is easier to review ignoring whitespace.
This change is need to get rid of CWalletTx copy constructor.
|
|
|
|
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.

This change is intended to make the bitcoin node and its rpc, network

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.

Remove findPruned and findFork, no more used after 17954.

Instead of calling getHeight, we rely on CWallet::m_last_block
processed_height where it's possible.
