Currently, when calculating block's bloom, we loop through all the
receipt logs to calculate the hash value. However, normally, after going
through applyTransaction, the receipt's bloom is already calculated
based on the receipt log, so the block's bloom can be calculated by just
ORing these receipt's blooms.

This PR addresses a flaw in the freezer table upgrade path.
In v1.15.0, freezer table v2 was introduced, including an additional
field (`flushOffset`) maintained in the metadata file. To ensure
backward compatibility, an upgrade path was implemented for legacy
freezer tables by setting `flushOffset` to the size of the index file.
However, if the freezer table is opened in read-only mode, this file
write operation is rejected, causing Geth to shut down entirely.
Given that invalid items in the freezer index file can be detected and
truncated, all items in freezer v0 index files are guaranteed to be
complete. Therefore, when operating in read-only mode, it is safe to
use the freezer data without performing an upgrade.
This is to prevent a crash on startup with a custom genesis configuration.
With this change in place, upgrading a chain created by geth v1.14.x and
below will now print an error instead of crashing:
Fatal: Failed to register the Ethereum service: invalid chain configuration: missing entry for fork "cancun" in blobSchedule
Arguably this is not great, and it should just auto-upgrade the config.
We'll address this in a follow-up PR for geth v1.15.2
This fixes an error where executing `evm run --dump ...` omits preimages
from the dump (because the statedb used for execution is a copy of
another instance).
The new SetCode transaction type introduces some additional complexity
when handling the transaction pool.
This complexity stems from two new account behaviors:
1. The balance and nonce of an account can change during regular
transaction execution *when they have a deployed delegation*.
2. The nonce and code of an account can change without any EVM execution
at all. This is the "set code" mechanism introduced by EIP-7702.
The first issue has already been considered extensively during the design
of ERC-4337, and we're relatively confident in the solution of simply
limiting the number of in-flight pending transactions an account can have
to one. This puts a reasonable bound on transaction cancellation. Normally
to cancel, you would need to spend 21,000 gas. Now it's possible to cancel
for around the cost of warming the account and sending value
(`2,600+9,000=11,600`). So 50% cheaper.
The second issue is more novel and needs further consideration.
Since authorizations are not bound to a specific transaction, we
cannot drop transactions with conflicting authorizations. Otherwise,
it might be possible to cherry-pick authorizations from txs and front
run them with different txs at much lower fee amounts, effectively DoSing
the authority. Fortunately, conflicting authorizations do not affect the
underlying validity of the transaction so we can just accept both.

This removes the method `TestingTTDBlock` introduced by #30744. It was
added to make the beacon consensus engine aware of the merge block in
tests without relying on the total difficulty. However, tracking the
merge block this way is very annoying. We usually configure forks in the
`ChainConfig`, but the method is on the consensus engine, which isn't
always created in the same place. By sidestepping the `ChainConfig` we
don't get the usual fork-order checking, so it's possible to enable the
merge before the London fork, for example. This in turn can lead to very
hard-to-debug outputs and validation errors.
So here I'm changing the consensus engine to check the
`MergeNetsplitBlock` instead. Alternatively, we assume a network is
merged if it has a `TerminalTotalDifficulty` of zero, which is a very
common configuration in tests.
Agreed to the following fork dates for Holesky and Sepolia on ACDC 150
Holesky slot: 3710976 (Mon, Feb 24 at 21:55:12 UTC)

After recent changes in Geth (removing TD):
39638c81c5 (diff-d70a44d4b7a0e84fe9dcca25d368f626ae6c9bc0b8fe9690074ba92d298bcc0d)
Non-Geth clients are failing many devp2p tests with an error:
`peering failed: status exchange failed: wrong TD in status: have 1 want 0`
Right now only Geth is passing it - all other clients are affected by
this change. I think there should be no validation of TD when checking `Status`
message in hive tests. Now Geth has 0 (and hive tests requires 0) and
all other clients have actual TD. And on real networks there is no validation
of TD when peering
Here we add some more changes for live tracing API v1.1:
- Hook `OnSystemCallStartV2` was introduced with `VMContext` as parameter.
- Hook `OnBlockHashRead` was introduced.
- `GetCodeHash` was added to the state interface
- The new `WrapWithJournal` construction helps with tracking EVM reverts in the tracer.

This PR changes the signature of `CalcExcessBlobGas` to take in just
the header timestamp instead of the whole object. It also adds a sanity
check for the parent->child block order to `VerifyEIP4844Header`.
A clarification was made to EIP-7691 stating that at the fork boundary
it is required to use the target blob count associated with the head
block, rather than the parent as implemented here.

This PR removes `locals` as a concept from transaction pools. Therefore,
the pool now acts as very a good simulation/approximation of how our
peers' pools behave. What this PR does instead, is implement a
locals-tracker, which basically is a little thing which, from time to
time, asks the pool "did you forget this transaction?". If it did, the
tracker resubmits it.
If the txpool _had_ forgotten it, chances are that the peers had also
forgotten it. It will be propagated again.
Doing this change means that we can simplify the pool internals, quite a
lot.
### The semantics of `local`
Historically, there has been two features, or usecases, that has been
combined into the concept of `locals`.
1. "I want my local node to remember this transaction indefinitely, and
resubmit to the network occasionally"
2. "I want this (valid) transaction included to be top-prio for my
miner"
This PR splits these features up, let's call it `1: local` and `2:
prio`. The `prio` is not actually individual transaction, but rather a
set of `address`es to prioritize.
The attribute `local` means it will be tracked, and `prio` means it will
be prioritized by miner.
For `local`: anything transaction received via the RPC is marked as
`local`, and tracked by the tracker.
For `prio`: any transactions from this sender is included first, when
building a block. The existing commandline-flag `--txpool.locals` sets
the set of `prio` addresses.

I hit this case while trying something with the simulated backend. The
EVM only enables instruction set forks after the merge when 'Random' is
set. In the simulated backend, the random value will be set via the
engine API for all blocks after genesis. But for the genesis block
itself, the random value will not be assigned in the vm.BlockContext
because the genesis has a non-zero difficulty. For my case, this meant
that estimateGas did not work for the first transaction sent on the
simulated chain, since the contract contained a PUSH0 instruction.
This could also be fixed by explicitly configuring a zero difficulty in
the simulated backend. However, I think that zero difficulty is a better
default these days.

This is a follow-up PR to #29792 to get rid of the data file sync.
**This is a non-backward compatible change, which increments the
database version from 8 to 9**.
We introduce a flushOffset for each freezer table, which tracks the position
of the most recently fsync’d item in the index file. When this offset moves
forward, it indicates that all index entries below it, along with their corresponding
data items, have been properly persisted to disk. The offset can also be moved
backward when truncating from either the head or tail of the file.
Previously, the data file required an explicit fsync after every mutation, which
was highly inefficient. With the introduction of the flush offset, the synchronization
strategy becomes more flexible, allowing the freezer to sync every 30 seconds
instead.
The data items above the flush offset are regarded volatile and callers must ensure
they are recoverable after the unclean shutdown, or explicitly sync the freezer
before any proceeding operations.

Fixes a typo in the error message within the `fuzzCrossG2Add`
function. The panic message incorrectly references "G1 point addition
mismatch" when it should be "G2 point addition mismatch," as the
function deals with G2 points.
This doesn't affect functionality but could cause confusion during
debugging. I've updated the message to reflect the correct curve.
This PR builds on #29040 and updates it to the new version of the spec.
I filled the EEST tests and they pass.

Same as #31015 but requires the contract to exist. Not compatible with
any verkle testnet up to now.
This adds a `isSytemCall` flag so that it is possible to detect when a
system call is executed, so that the code execution and other locations
are not added to the witness.

The total difficulty is the sum of all block difficulties from genesis
to a certain block. This value was used in PoW for deciding which chain
is heavier, and thus which chain to select. Since PoS has a different
fork selection algorithm, all blocks since the merge have a difficulty
of 0, and all total difficulties are the same for the past 2 years.
Whilst the TDs are mostly useless nowadays, there was never really a
reason to mess around removing them since they are so tiny. This
reasoning changes when we go down the path of pruned chain history. In
order to reconstruct any TD, we **must** retrieve all the headers from
chain head to genesis and then iterate all the difficulties to compute
the TD.
In a world where we completely prune past chain segments (bodies,
receipts, headers), it is not possible to reconstruct the TD at all. In
a world where we still keep chain headers and prune only the rest,
reconstructing it possible as long as we process (or download) the chain
forward from genesis, but trying to snap sync the head first and
backfill later hits the same issue, the TD becomes impossible to
calculate until genesis is backfilled.
All in all, the TD is a messy out-of-state, out-of-consensus computed
field that is overall useless nowadays, but code relying on it forces
the client into certain modes of operation and prevents other modes or
other optimizations. This PR completely nukes out the TD from the node.
It doesn't compute it, it doesn't operate on it, it's as if it didn't
even exist.
Caveats:
- Whenever we have APIs that return TD (devp2p handshake, tracer, etc.)
we return a TD of 0.
- For era files, we recompute the TD during export time (fairly quick)
to retain the format content.
- It is not possible to "verify" the merge point (i.e. with TD gone, TTD
is useless). Since we're not verifying PoW any more, just blindly trust
it, not verifying but blindly trusting the many year old merge point
seems just the same trust model.
- Our tests still need to be able to generate pre and post merge blocks,
so they need a new way to split the merge without TTD. The PR introduces
a settable ttdBlock field on the consensus object which is used by tests
as the block where originally the TTD happened. This is not needed for
live nodes, we never want to generate old blocks.
- One merge transition consensus test was disabled. With a
non-operational TD, testing how the client reacts to TTD is useless, it
cannot react.
Questions:
- Should we also drop total terminal difficulty from the genesis json?
It's a number we cannot react on any more, so maybe it would be cleaner
to get rid of even more concepts.

This implements a basic mechanism to query the node's external IP using
a STUN server. There is a built-in list of public STUN servers for convenience.
The new detection mechanism must be selected explicitly using `--nat=stun`
and is not enabled by default in Geth.
Fixes#30881
