validation: correct lifetime of precomputed tx data

This makes sure `txsdata` always outlives the Script check queue (since local
objects are destructed in reverse order of construction).

This is the root cause for a security vulnerability reported by Cory Fields in
2024 that could be exploited by crafting an invalid block to cause nodes to
read freed memory. The vulnerability was covertly fixed in commit
`492e1f09943fcb6145c21d470299305a19e17d8b`.

See security advisory for CVE-2024-52911 for more details.

AI analysis · Critical 87/100

This commit fixes a memory safety bug in Bitcoin Core's block validation. When checking a new block, the program creates a queue of script checks that may run on multiple threads in the background. It also precomputes some transaction data used by those checks. Previously, the precomputed data was destroyed before the background check queue finished, so the workers could read memory that had already been freed. An attacker could craft a malicious block to trigger this, potentially causing crashes, memory corruption, or worse. The fix simply moves the precomputed data variable so it is created before the queue and destroyed after it, guaranteeing the data stays alive as long as the checks need it.

This is a pure variable-name cleanup in Bitcoin Core's ARM SHA-256 code. The old names (ABEF_SAVE/CDGH_SAVE) were misleading labels; the new names (ABCD_SAVE/EFGH_SAVE) match how ARM's SHA-256 instructions actually order the hash state. No instructions, values, or behavior change.

AI analysis · Low 34/100

This commit changes a Bitcoin Core internal helper function so that it can now report failure when a PSBT (Partially Signed Bitcoin Transaction) is internally inconsistent. Previously, the helper would build transaction precomputation data without checking whether the underlying unsigned transaction could actually be constructed. Now it returns an optional value that callers must check, and they reject or abort the operation if the transaction cannot be valid. This is a defensive hardening change that prevents the code from continuing with malformed PSBTs.

This commit finishes implementing the 'AddInput' and 'AddOutput' methods for PSBT version 2 in Bitcoin Core. PSBTs are files used to collaboratively build or sign Bitcoin transactions offline. Previously, adding inputs/outputs to a PSBTv2 would silently fail (return false). The change now properly checks version compatibility, respects the 'modifiable' flags that say whether inputs/outputs may be added, and handles time-lock consistency when new inputs are appended. It is a feature-completion patch with defensive checks, not a fix for an active vulnerability.

This commit adds a helper function that calculates when a Bitcoin transaction becomes valid based on time or block height locks inside a Partially Signed Bitcoin Transaction (PSBT). It also makes the existing unsigned-transaction builder use this new calculation instead of always using a simple fallback value. The change appears to be a correctness improvement for PSBT version 2 locktime handling, not an obvious security fix, but it prevents a PSBT from being turned into a transaction when its inputs disagree about whether the lock is based on time or block height.

Replace PSBT.tx with PSBT::GetUnsignedTx and PSBT::GetUniqueID

The global unsigned tx is decomposed into separate fields inside of
PSBT, which mirrors what PSBTv2 will do. However, we still need to get
the global unsigned tx so PSBT::GetUnsignedTx is introduced to do that.
In order to also have a stable unique ID, we also introduce
PSBT::GetUniqueID to replace uses of PSBT.tx.GetHash().

This commit refactors how Bitcoin Core handles Partially Signed Bitcoin Transactions (PSBTs). Previously, a PSBT stored a complete copy of the unsigned transaction. Now, the transaction is broken into separate fields and reconstructed on demand. The change also introduces a stable unique ID for each PSBT. This is primarily a code-cleanup and preparation step for a future PSBT version 2, not a direct fix for an active security bug.

Allow specifying PSBT version in constructor

The constructor will create the PSBT of the specified version, as long
as it is 0 or 2.

This change lets the PSBT constructor choose between version 0 or version 2 when creating a new Partially Signed Bitcoin Transaction. It also fixes a small consistency bug in the joinpsbts RPC where newly created PSBTs during joining/shuffling were always version 0, even when the inputs being joined were version 2. There is no direct evidence this is a security fix, and the new version parameter is guarded by an assertion that only allows 0 or 2.

This commit changes the default version number used when Bitcoin Core creates new Partially Signed Bitcoin Transactions (PSBTs) from version 0 to version 2. PSBT is a standard format for passing around unsigned or partially signed transactions between wallets and signers. The change itself is a one-line default-value update plus a test that confirms new PSBTs are created as version 2. It does not fix a memory corruption bug, crash, or remote-code-execution flaw, and there is no evidence in the commit or supplied references that it addresses a known security incident.

This commit adds a new test case to Bitcoin Core's functional test suite. It verifies that two PSBT (Partially Signed Bitcoin Transaction) version 0 encodings—one with the version field explicitly set to 0 and one with it omitted—can be merged together correctly. There is no code change to the actual Bitcoin Core node software, only a new regression test.

This commit is a small internal refactor in Bitcoin Core's Partially Signed Bitcoin Transaction (PSBT) handling. It makes each PSBT input and output aware of which PSBT version it belongs to, currently hard-coded to version 0. The change does not fix a known bug or vulnerability by itself; it appears to lay groundwork for future PSBT version support. There is no evidence in the commit or supplied references that this is a security patch.

psbt: Use PSBTInput and PSBTOutput fields instead of accessing global tx

PSBTInput now has the previous txid and output index, and PSBTOutput has
the amount and script. We no longer need to access the global unsigned
tx for these fields.

Additionally, we can change iterating tx.vin and tx.vout to psbtx.inputs
and psbtx.outputs.

This is in prepration for use with PSBTv2 where the global unsigned tx
will not exist.

This commit is a code cleanup in Bitcoin Core's Partially Signed Bitcoin Transaction (PSBT) handling. It changes internal code to read input and output details from the PSBT data structures themselves rather than from the global unsigned transaction. The stated goal is to prepare for a future PSBT version (PSBTv2) where the global unsigned transaction may not exist. There is no direct security fix here, but any inconsistency between the PSBT fields and the global transaction could, in principle, lead to wrong analysis or signing behavior. The patch appears to keep behavior equivalent by using the same data through a different path.

This commit is a small code cleanup: it adds a helper function called GetOutPoint to PSBTInput and replaces several direct accesses to transaction input data with calls to that helper. There is no change in behavior or security fix visible in the diff. It appears to be a refactoring to make the code easier to maintain.

This commit refactors how inputs and outputs are added to Partially Signed Bitcoin Transactions (PSBTs). Previously, callers had to pass both a raw transaction input/output and a PSBT-specific input/output, which could become inconsistent. Now the functions accept only the PSBT-specific object and derive the raw transaction data from it. For PSBT version 2, the code currently just returns false and does not actually add anything, which appears to be intentional but incomplete support. The change reduces the risk of mismatched data and duplicate inputs, but it is primarily a code-quality and API-safety improvement rather than a fix for an active exploit.
