…chain#3700) Cherry-pick of go-ethereum 8581125a2 (PR #33839). The cgo path in secp256k1/secp256.go already rejects non-32-byte hashes, but the nocgo (pure-Go) path did not. PR #33104 added the check to Sign and sigToPub but missed VerifySignature. Without it, a wrong-length hash gets passed to decred's Verify and silently gives a bogus result — a truncated hash may match a different signature, an extended hash silently ignores extra bytes.

…898) (bnb-chain#3710) Fixes #34881 This fixes a hang in `Table.waitForNodes`. It is a replacement for PRs - #34890 doesn't really fix the issue, just makes it less likely - #33665 tries to fix it by moving the feed send outside of the lock I created this PR because I want to keep the synchronous node feed sending in `Table.nodeAdded`. --------- Co-authored-by: Felix Lange <fjl@twurst.com> Co-authored-by: Csaba Kiraly <csaba.kiraly@gmail.com>
…0) (bnb-chain#3708) * eth/downloader: drop peers sending invalid bodies or receipts (#34745) Cherry-pick of go-ethereum 75a64ee34 (PR #34745). - Fixes an error shadowing issue in the deliver() function, where a stale result from GetDeliverySlot caused the original failure to be overwritten by errStaleDelivery. - Adds errInvalidBody and errInvalidReceipt propagation via res.Done so the eth protocol handler tears down the connection of peers sending invalid responses, instead of just adjusting capacity while keeping the peer connected. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * eth/downloader: use batch index in deliver reconstruct (#34870) Cherry-pick of go-ethereum 5b837e578 (PR #34870). reconstruct() indexes into the parallel response slices (bodies, receipts). After PR #34745 (now applied in this stack) moved `accepted++` inside the success branch, passing `accepted` to `reconstruct()` underflowed the response index whenever an earlier header in the same batch hit a stale slot — the next successful slot would read from the wrong response slice element. Switch to the loop's range index `k`, which always tracks the response position regardless of stale gaps. NOTE: based on `fix/downloader-drop-invalid-peers` (PR bnb-chain#3699) — must land after / merged together with that PR.

…t (#34680) (bnb-chain#3706) Cherry-pick of go-ethereum 3772bb536 (PR #34680). accountTip and storageTip both returned common.Hash{} as the "not found" sentinel. That collides with a legitimate disk-layer fallback when the disk layer's root is itself the zero hash — as is the case for a fresh verkle/bintrie database whose empty trie hashes to EmptyVerkleHash. Switch to a (hash, ok) return signature so callers can distinguish the two cases. Update lookupAccount/lookupStorage at the call sites. The upstream regression test (TestLookupZeroBaseRootFallback) depends on test helpers not present in BSC's layertree_test.go and is omitted; the existing pathdb test suite (TestAccountLookup / TestStorageLookup et al.) still exercises the happy path. This is defensive hardening — BSC does not activate verkle in production, so the zero-root collision is theoretical today. Recommended as prerequisite for future verkle adoption.

…b-chain#3718) * crypto: add hash length check in nocgo sigToPub Upstream PR #33839 added the hash length guard to both VerifySignature and sigToPub. The prior backport only covered VerifySignature; mirror the same check in sigToPub so callers like Ecrecover reject malformed hash inputs with a clear error instead of relying on downstream library behavior. * triedb/pathdb: add regression test for zero-base-root fallback Cover the sentinel collision fixed in the prior commit: when the disk layer root is common.Hash{} (e.g. a fresh verkle/bintrie database whose empty trie hashes to zero), the legitimate fall-through to the disk layer must not be mistaken for the stale-state sentinel. Pins both the fall-through and the still-stale-on-unknown-state contract so a future refactor that always returns ok=true would fail here.

…nb-chain#3711) In openFreezerFileForAppend, if Seek fails after the file is successfully opened, the file handle is not closed, leaking a descriptor. Similarly in newTable, if opening the meta file fails, the already-opened index file is not closed. And if newMetadata fails, both the index and meta files are leaked. Under repeated error conditions (e.g., corrupted filesystem), these leaks accumulate and may exhaust the OS file descriptor limit, causing cascading failures.

…in#3707) Cherry-pick of go-ethereum b9c5fe6d2 (PR #34862). The mux tracer fanned out every standard hook to its children but never forwarded OnSystemCall{Start,End}. Tracers that rely on these — like logger.jsonLogger, which uses the start hook to silence its opcode hook for the duration of a system call — never got the signal when wrapped behind a mux. Combining --trace with --opcode-count in evm t8n produces exactly that wrapping, and the first system call (e.g. ProcessBeaconBlockRoot) crashes t8n on nil env deref. Forwards OnSystemCallStartV2 (with V1 fallback per child) and OnSystemCallEnd through the mux. Same precedence as core/state_processor.go.

…b-chain#3705) Cherry-pick of go-ethereum ea1cf7bf5 (PR #34787) — alternative to PR #34746 implementing the simpler approach: when serving GetBlockBodies / GetReceipts and a requested item is unavailable, stop serving instead of silently dropping it. Requests for unavailable items are typically a sign that the peer is following a different fork; replying with a sparse list is misleading because the dropped slots are silently elided. Halting at the first gap gives the requester a clearer signal and saves work. Adapted to BSC's two receipts handlers (68 and 69) which retain the empty-receipts-root branch — that branch continues to serve. Test adjusted to match the new "stop at gap" semantics.

…4888) (bnb-chain#3701) Cherry-pick of go-ethereum e1e3eaa38 (PR #34888). The discv4 read loop allocates `buf` once and reuses it for every ReadFromUDPAddrPort call. When a packet fails handlePacket, the raw buffer `buf[:nbytes]` was sent by reference to the `unhandled` channel; by the time the consumer (discv5 in mixed-mode) processes it, the next ReadFromUDPAddrPort had overwritten the buffer contents. bytes.Clone the slice before sending so the consumer owns an independent copy.

…ers (#34743) (bnb-chain#3702) * p2p/discover: fix timeout loop early exit when removing expired matchers (#34743) Cherry-pick of go-ethereum 51c97216c (PR #34743), adapted minimally to keep BSC's manual list iteration (BSC has not adopted the upstream iterList helper, so the upstream regression fixed by 60db25b07 never applied here). In both the gotreply and timeout-deadline loops, plist.Remove(el) invalidates el.Next(), so the next iteration's el.Next() returns nil and the loop exits after removing only the first expired/done matcher. Save el.Next() before calling plist.Remove(el) so iteration continues through every entry. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * p2p/discover: fix resetTimeout loop early exit on clock-warp removal The prior backport of upstream #34743 ported the gotreply and timeout loops but missed the resetTimeout loop. When the system clock jumps backward, expired matchers can still be removed inside resetTimeout via plist.Remove(el); after removal el.Next() returns nil, exiting the loop early and skipping subsequent stale matchers. Save the next element before removing the current one, matching the pattern used in the other two loops. --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* eth/tracers/logger: fix exclude address list (#34887) Cherry-pick of go-ethereum f7b7d4c7e (PR #34887). In NewAccessListTracer, when a prelude AccessList entry's address was in addressesToExclude, list.addAddress was correctly skipped — but the inner for-loop still called list.addSlot for every slot under that address, causing the excluded address to leak into the tracer's output with storage keys attached. Refactored to `continue` on the excluded address so both addAddress and the slot loop are skipped together.

…ade (bnb-chain#3721) Wire the Pasteur hardfork to upgrade two system contracts whose bytecode changed on the genesis-contract side: - StakeHub (0x2002): propagate slash eviction to BSCValidatorSet after consensus-key rotation (bsc-genesis-contract bnb-chain#664) - BSCGovernor (0x2004): reject blacklisted voter on castVoteBySig (bnb-chain#667) Adds the `pasteur` bytecode package (StakeHub/Governor for Mainnet, Chapel, Rialto) and applies it in upgradeBuildInSystemContract when IsOnPasteur. Bytecode extracted from the regenerated genesis (bsc-genesis-contract commit 3f02a2e); CommitUrl points there for now and should be updated to the Pasteur release merge commit once available. PasteurTime scheduling in params/config.go is intentionally left unset. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

… block at Pasteur (bnb-chain#3726) Builds on the Pasteur precompile set introduced in bnb-chain#3623. The legacy v1 Tendermint light-client precompiles 0x64 (tmHeaderValidate) and 0x65 (iavlMerkleProofValidate) are only reachable via the deprecated BC<->BSC cross-chain stack (contracts/deprecated/), which no longer exists. Rename the existing *Nano suspend handlers to tmHeaderValidateDeprecated / iavlMerkleProofValidateDeprecated (error "deprecated") and map 0x64/0x65 to them in the Pasteur set, deprecating them from Pasteur. For the v2 cometBFT light-client (0x67), the verification work scales with the light block's validator/signature count while the gas was flat. Price the Pasteur variant's RequiredGas per input byte (CometBFTLightBlockValidatePerByteGas) so gas tracks the real CPU/memory cost (cf. the per-key pricing of 0x66 blsSignatureVerify). The pre-Pasteur Hertz variant keeps the flat gas so earlier blocks replay identically. Note: the per-byte rate is tunable; raising 0x67 gas affects the live Greenfield/op-stack relayer gas budget and should be coordinated.

…2.6 (bnb-chain#3727) Update the Pasteur upgrade CommitUrl for StakeHub (0x2002) and BSCGovernor (0x2004) from the interim commit 3f02a2e to the tagged release v1.2.6 (commit 041881a02475638b19f3d840871b7621cdebd8f8). The embedded bytecode is unchanged: verified the StakeHub/Governor code for Mainnet/Chapel/Rialto matches the v1.2.6 genesis byte-for-byte, so this only corrects the provenance reference to the official release tag.

…bnb-chain#3728) The fake-beacon service (bnb-chain#2678) is an internal-only op-stack blob/DA shim, off by default and bound to localhost. Its block-number lookup (fetchBlockNumberByTime) has an unbounded retry loop with no lower bound and no ctx cancellation, plus an inner nil-header dereference, so an operator who enables and exposes it can leak handler goroutines (SRC-2026-1000). Rather than patch an auxiliary, default-off feature, the service is removed entirely. Removes the beacon/fakebeacon package and its --fake-beacon[.addr|.port] flags and startup wiring in cmd/geth and cmd/utils. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
