Upstream merge from go-ethereum/v1.11.6 (#901) 
* ethdb/pebble: fix nil callbacks (#26650)

* eth/downloader: fix timeout resurrection panic (#26652)

* common/prque, eth/downloader: fix timeout resurrection panic

* go.mod: update pebble to latest master (#26654)

* core/vm: set tracer-observable `value` of a delegatecall to match parent `value` (#26632)

This is a breaking change in the tracing hooks API as well as semantics of the callTracer:

- CaptureEnter hook provided a nil value argument in case of DELEGATECALL. However to stay consistent with how delegate calls behave in EVM this hook is changed to pass in the value of the parent call.
- callTracer will return parent call's value for DELEGATECALL frames.

* eth/filters: avoid block body retrieval when no matching logs (#25199)

Logs stored on disk have minimal information. Contextual information such as block
number, index of log in block, index of transaction in block are filled in upon request.
We can fill in all these fields only having the block header and list of receipts.
But determining the transaction hash of a log requires the block body.

The goal of this PR is postponing this retrieval until we are sure we the transaction hash.
It happens often that the header bloom filter signals there might be matches in a block,
but after actually checking them reveals the logs do not match. We want to avoid fetching
the body in this case.

Note that this changes the semantics of Backend.GetLogs. Downstream callers of
GetLogs now assume log context fields have not been derived, and need to call
DeriveFields on the logs if necessary.

* eth/tracers: more fork overrides in traceBlockToFile (#26655)

This change allows all post-Berlin forks to be specified as overrides for futureForkBlock in the config parameter for traceBlockToFile.

* ethdb/pebble: Fix `MemTableStopWritesThreshold` (#26692)

MemTableStopWritesThreshold was set to the max size of all memtables before blocking writing but should be set to the max number of memtables. This is documented [here](https://github.com/cockroachdb/pebble/blob/master/options.go#L738-L742).

* eth/downloader: handle missing withdrawals if empty list is expected (#26675)

This PR relaxes the block body ingress handling a bit: if block body withdrawals are missing (but expected to be empty), the body withdrawals are set to 'empty list' before being passed to upper layers. 

This fixes an issue where a block passed from EthereumJS to geth was deemed invalid.

* all: remove deprecated uses of math.rand (#26710)

This PR is a (superior) alternative to https://github.com/ethereum/go-ethereum/pull/26708, it handles deprecation, primarily two specific cases. 

`rand.Seed` is typically used in two ways
- `rand.Seed(time.Now().UnixNano())` -- we seed it, just to be sure to get some random, and not always get the same thing on every run. This is not needed, with global seeding, so those are just removed. 
- `rand.Seed(1)` this is typically done to ensure we have a stable test. If we rely on this, we need to fix up the tests to use a deterministic prng-source. A few occurrences like this has been replaced with a proper custom source. 

`rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.

* eth/tracers: add native flatCallTracer (aka parity style tracer) (#26377)

Adds support for a native call tracer with the Parity format, which outputs call frames
in a flat array. This tracer accepts the following options:

- `convertParityErrors: true` will convert error messages to match those of Parity
- `includePrecompiles: true` will report all calls to precompiles. The default
  matches Parity's behavior where CALL and STATICCALLs to precompiles are excluded

Incompatibilities with Parity include:

- Parity removes the result object in case of failure. This behavior is maintained
  with the exception of reverts. Revert output usually contains useful information,
  i.e. Solidity revert reason.
- The `gasUsed` field accounts for intrinsic gas (e.g. 21000 for simple transfers)
  and refunds unlike Parity
- Block rewards are not reported

* metrics: improve accuracy of CPU gauges (#26793)

This PR changes metrics collection to actually measure the time interval between collections, rather
than assume 3 seconds. I did some ad hoc profiling, and on slower hardware (eg, my Raspberry Pi 4)
I routinely saw intervals between 3.3 - 3.5 seconds, with some being as high as 4.5 seconds. This
will generally cause the CPU gauge readings to be too high, and in some cases can cause impossibly
large values for the CPU load metrics (eg. greater than 400 for a 4 core CPU).

* accounts/usbwallet: mitigate ledger app chunking issue (#26773)

This PR mitigates an issue with Ledger's on-device RLP deserialization, see
https://github.com/LedgerHQ/app-ethereum/issues/409

Ledger's RLP deserialization code does not validate the length of the RLP list received,
and it may prematurely enter the signing flow when a APDU chunk boundary falls immediately
before the EIP-155 chain_id when deserializing a transaction. Since the chain_id is
uninitialized, it is 0 during this signing flow. This may cause the user to accidentally
sign the transaction with chain_id = 0. That signature would be returned from the device 1
packet earlier than expected by the communication loop. The device blocks the
second-to-last packet waiting for the signer flow, and then errors on the successive
packet (which contains the chain_id, zeroed r, and zeroed s)

Since the signature's early arrival causes successive errors during the communication
process, geth does not parse the improper signature produced by the device, and therefore
no improperly-signed transaction can be created. User funds are not at risk.

We mitigate by selecting the highest chunk size that leaves at least 4 bytes in the
final chunk.

This changes the test to match the comment description. Using timestampedConfig in this test case is incorrect, the comment says 'local is at Gray Glacier' and isn't aware of more forks.

* cmd/evm: update readmes for the tests (#26841)

* core, core/types: plain Message struct (#25977)

Here, the core.Message interface turns into a plain struct and
types.Message gets removed.

This is a breaking change to packages core and core/types. While we do
not promise API stability for package core, we do for core/types. An
exception can be made for types.Message, since it doesn't have any
purpose apart from invoking the state transition in package core.
types.Message was also marked deprecated by the same commit it
got added in, 4dca5d4db7 (November 2016).

The core.Message interface was added in December 2014, in commit
db494170dc, for the purpose of 'testing' state transitions. It's the
same change that made transaction struct fields private. Before that,
the state transition used *types.Transaction directly.

Over time, multiple implementations of the interface accrued across
different packages, since constructing a Message is required whenever
one wants to invoke the state transition. These implementations all
looked very similar, a struct with private fields exposing the fields
as accessor methods.

By changing Message into a struct with public fields we can remove all
these useless interface implementations. It will also hopefully
simplify future changes to the type with less updates to apply across
all of go-ethereum when a field is added to Message.

* Increase websocket frame size (from erigon rpc client) (#26883)

Originally submitted at https://github.com/ledgerwatch/erigon/pull/2739

example block failure: https://etherscan.io/tx/0x1317d973a55cedf9b0f2df6ea48e8077dd176f5444a3423368a46d6e4db89982#internal

When a database failure occurs, bubble it up a into statedb, and report it in suitable places, such as during a 'bad block' report.

* consensus: improve consensus engine definition (#26871)

Makes clear the distinction between Finalize and FinalizedAndAssemble:

- In Finalize function, a series of state operations are applied according to consensus rules. The statedb is mutated and the root hash can be checked and compared afterwards.

This function should be used in block processing(receive afrom network and apply it locally) but not block generation.

- In FinalizeAndAssemble function, after applying state mutations, the block is also to be assembled with the latest
  state root computed, updating the header. 

 This function should be used in block generation only.

* cmd/evm, tests: record preimages if dump is expected (#26955)

With #25287 we made it so that preimages were not recorded by default. This had the side effect that the evm command is no longer able to dump state since it does a preimage lookup to determine the address represented by a key.

This change enables the recording of preimages when the dump command is given.

* core/state: add account address to Trie slot accessors (#26934)

This changes the Trie interface to add the plain account address as a
parameter to all storage-related methods.

After the introduction of the TryAccount* functions, TryGet, TryUpdate and
TryDelete are now only meant to read an account's storage. In their current
form, they assume that an account storage is stored in a separate trie, and
that the hashing of the slot is independent of its account's address.

The proposed structure for a stateless storage breaks these two
assumptions: the hashing of a slot key requires the address and all slots
and accounts are stored in a single trie.

This PR therefore adds an address parameter to the interface. It is ignored
in the MPT version, so this change has no functional impact, however it
will reduce the diff size when merging verkle trees.

* metrics: add cpu counters (#26796)

This PR adds counter metrics for the CPU system and the Geth process.
Currently the only metrics available for these items are gauges. Gauges are
fine when the consumer scrapes metrics data at the same interval as Geth
produces new values (every 3 seconds), but it is likely that most consumers
will not scrape that often. Intervals of 10, 15, or maybe even 30 seconds
are probably more common.

So the problem is, how does the consumer estimate what the CPU was doing in
between scrapes. With a counter, it's easy ... you just subtract two
successive values and divide by the time to get a nice, accurate average.
But with a gauge, you can't do that. A gauge reading is an instantaneous
picture of what was happening at that moment, but it gives you no idea
about what was going on between scrapes. Taking an average of values is
meaningless.

* metrics/influxdb: use smaller dependency and reuse code between v1 and v2 reporters  (#26963)

This change switches to use the smaller influxdata/influxdb1-client package instead of depending on the whole infuxdb package. The new smaller client is very similar to the influxdb-v2 client, which made it possible to refactor the two reporters to reuse code a lot more.

This change enables log rotation, which can be activated using the flag --log.rotate. Additional parameters that can be given are: 

  - log.maxsize to set maximum size before files are rotated,
  - log.maxbackups to set how many files are retailed, 
  - log.maxage to configure max age of rotated files, 
  - log.compress whether to compress rotated files

The way to configure location of the logfile(s) is left unchanged, via the `log.logfile` parameter.

* core/txpool: move some validation to outside of mutex (#27006)

Currently, most of transaction validation while holding the txpool mutex: one exception being an early-on signature check. 

This PR changes that, so that we do all non-stateful checks before we entering the mutex area. This means they can be performed in parallel, and to enable that, certain fields have been made atomic bools and uint64.

This includes a semantic change to the `callTracer` as well as `flatCallTracer`.
The value of field `gas` in the **first** call frame will change as follows:

- It previously contained gas available after initial deductions (i.e. tx costs)
- It will now contain the full tx gasLimit value

* build: upgrade -dlgo version to Go 1.20.3

* core/txpool: disallow future churn by remote txs (#26907)

Prior to this change, it was possible that transactions are erroneously deemed as 'future' although they are in fact 'pending', causing them to be dropped due to 'future' not being allowed to replace 'pending'. 

This change fixes that, by doing a more in-depth inspection of the queue.

* core, miner: drop transactions from the same sender when error occurs (#27038)

This PR unifies the error handling in miner. 

Whenever an error occur while applying a transaction, the transaction should be regarded as invalid and all following transactions from the same sender not executable because of the nonce restriction. The only exception is the `nonceTooLow` error which is handled separately.

The EIP150Hash was an idea where, after the fork, we hardcoded the forked hash as an extra defensive mechanism. It wasn't really used, since forks weren't contentious and for all the various testnets and private networks it's been a hassle to have around. 

This change removes that config field.

node: refactor package node (#21105) 
This PR significantly changes the APIs for instantiating Ethereum nodes in
a Go program. The new APIs are not backwards-compatible, but we feel that
this is made up for by the much simpler way of registering services on
node.Node. You can find more information and rationale in the design
document: https://gist.github.com/renaynay/5bec2de19fde66f4d04c535fd24f0775.

There is also a new feature in Node's Go API: it is now possible to
register arbitrary handlers on the user-facing HTTP server. In geth, this
facility is used to enable GraphQL.

There is a single minor change relevant for geth users in this PR: The
GraphQL API is no longer available separately from the JSON-RPC HTTP
server. If you want GraphQL, you need to enable it using the
./geth --http --graphql flag combination.

The --graphql.port and --graphql.addr flags are no longer available.

50b872bf05 p2p, swarm: fix node up races by granular locking (#18976) 
* swarm/network: DRY out repeated giga comment

I not necessarily agree with the way we wait for event propagation.
But I truly disagree with having duplicated giga comments.

* p2p/simulations: encapsulate Node.Up field so we avoid data races

The Node.Up field was accessed concurrently without "proper" locking.
There was a lock on Network and that was used sometimes to access
the  field. Other times the locking was missed and we had
a data race.

For example: https://github.com/ethereum/go-ethereum/pull/18464
The case above was solved, but there were still intermittent/hard to
reproduce races. So let's solve the issue permanently.

resolves: ethersphere/go-ethereum#1146

* p2p/simulations: fix unmarshal of simulations.Node

Making Node.Up field private in 13292ee897
broke TestHTTPNetwork and TestHTTPSnapshot. Because the default
UnmarshalJSON does not handle unexported fields.

Important: The fix is partial and not proper to my taste. But I cut
scope as I think the fix may require a change to the current
serialization format. New ticket:
https://github.com/ethersphere/go-ethereum/issues/1177

* p2p/simulations: Add a sanity test case for Node.Config UnmarshalJSON

* p2p/simulations: revert back to defer Unlock() pattern for Network

It's a good patten to call `defer Unlock()` right after `Lock()` so
(new) error cases won't miss to unlock. Let's get back to that pattern.

The patten was abandoned in 85a79b3ad3,
while fixing a data race. That data race does not exist anymore,
since the Node.Up field got hidden behind its own lock.

* p2p/simulations: consistent naming for test providers Node.UnmarshalJSON

* p2p/simulations: remove JSON annotation from private fields of Node

As unexported fields are not serialized.

* p2p/simulations: fix deadlock in Network.GetRandomDownNode()

Problem: GetRandomDownNode() locks -> getDownNodeIDs() ->
GetNodes() tries to lock -> deadlock

On Network type, unexported functions must assume that `net.lock`
is already acquired and should not call exported functions which
might try to lock again.

* p2p/simulations: ensure method conformity for Network

Connect* methods were moved to p2p/simulations.Network from
swarm/network/simulation. However these new methods did not follow
the pattern of Network methods, i.e., all exported method locks
the whole Network either for read or write.

* p2p/simulations: fix deadlock during network shutdown

`TestDiscoveryPersistenceSimulationSimAdapter` often got into deadlock.
The execution was stuck on two locks, i.e, `Kademlia.lock` and
`p2p/simulations.Network.lock`. Usually the test got stuck once in each
20 executions with high confidence.

`Kademlia` was stuck in `Kademlia.EachAddr()` and `Network` in
`Network.Stop()`.

Solution: in `Network.Stop()` `net.lock` must be released before
calling `node.Stop()` as stopping a node (somehow - I did not find
the exact code path) causes `Network.InitConn()` to be called from
`Kademlia.SuggestPeer()` and that blocks on `net.lock`.

Related ticket: https://github.com/ethersphere/go-ethereum/issues/1223

* swarm/state: simplify if statement in DBStore.Put()

* p2p/simulations: remove faulty godoc from private function

The comment started with the wrong method name.

The method is simple and self explanatory. Also, it's private.
=> Let's just remove the comment.

p2p/simulations: fix a deadlock and clean up adapters (#17891) 
This fixes a rare deadlock with the inproc adapter:

- A node is stopped, which acquires Network.lock.
- The protocol code being simulated (swarm/network in my case)
  waits for its goroutines to shut down.
- One of those goroutines calls into the simulation to add a peer,
  which waits for Network.lock.

The fix for the deadlock is really simple, just release the lock
before stopping the simulation node.

Other changes in this PR clean up the exec adapter so it reports
node startup errors better and remove the docker adapter because
it just adds overhead.

In the exec adapter, node information is now posted to a one-shot
server. This avoids log parsing and allows reporting startup
errors to the simulation host.

A small change in package node was needed because simulation
nodes use port zero. Node.{HTTP,WS}Endpoint now return the live
endpoints after startup by checking the TCP listener.

all: new p2p node representation (#17643) 
Package p2p/enode provides a generalized representation of p2p nodes
which can contain arbitrary information in key/value pairs. It is also
the new home for the node database. The "v4" identity scheme is also
moved here from p2p/enr to remove the dependency on Ethereum crypto from
that package.

Record signature handling is changed significantly. The identity scheme
registry is removed and acceptable schemes must be passed to any method
that needs identity. This means records must now be validated explicitly
after decoding.

The enode API is designed to make signature handling easy and safe: most
APIs around the codebase work with enode.Node, which is a wrapper around
a valid record. Going from enr.Record to enode.Node requires a valid
signature.

* p2p/discover: port to p2p/enode

This ports the discovery code to the new node representation in
p2p/enode. The wire protocol is unchanged, this can be considered a
refactoring change. The Kademlia table can now deal with nodes using an
arbitrary identity scheme. This requires a few incompatible API changes:

  - Table.Lookup is not available anymore. It used to take a public key
    as argument because v4 protocol requires one. Its replacement is
    LookupRandom.
  - Table.Resolve takes *enode.Node instead of NodeID. This is also for
    v4 protocol compatibility because nodes cannot be looked up by ID
    alone.
  - Types Node and NodeID are gone. Further commits in the series will be
    fixes all over the the codebase to deal with those removals.

* p2p: port to p2p/enode and discovery changes

This adapts package p2p to the changes in p2p/discover. All uses of
discover.Node and discover.NodeID are replaced by their equivalents from
p2p/enode.

New API is added to retrieve the enode.Node instance of a peer. The
behavior of Server.Self with discovery disabled is improved. It now
tries much harder to report a working IP address, falling back to
127.0.0.1 if no suitable address can be determined through other means.
These changes were needed for tests of other packages later in the
series.

* p2p/simulations, p2p/testing: port to p2p/enode

No surprises here, mostly replacements of discover.Node, discover.NodeID
with their new equivalents. The 'interesting' API changes are:

 - testing.ProtocolSession tracks complete nodes, not just their IDs.
 - adapters.NodeConfig has a new method to create a complete node.

These changes were needed to make swarm tests work.

Note that the NodeID change makes the code incompatible with old
simulation snapshots.

* whisper/whisperv5, whisper/whisperv6: port to p2p/enode

This port was easy because whisper uses []byte for node IDs and
URL strings in the API.

* eth: port to p2p/enode

Again, easy to port because eth uses strings for node IDs and doesn't
care about node information in any way.

* les: port to p2p/enode

Apart from replacing discover.NodeID with enode.ID, most changes are in
the server pool code. It now deals with complete nodes instead
of (Pubkey, IP, Port) triples. The database format is unchanged for now,
but we should probably change it to use the node database later.

* node: port to p2p/enode

This change simply replaces discover.Node and discover.NodeID with their
new equivalents.

* swarm/network: port to p2p/enode

Swarm has its own node address representation, BzzAddr, containing both
an overlay address (the hash of a secp256k1 public key) and an underlay
address (enode:// URL).

There are no changes to the BzzAddr format in this commit, but certain
operations such as creating a BzzAddr from a node ID are now impossible
because node IDs aren't public keys anymore.

Most swarm-related changes in the series remove uses of
NewAddrFromNodeID, replacing it with NewAddr which takes a complete node
as argument. ToOverlayAddr is removed because we can just use the node
ID directly.

54aeb8e4c0 p2p/simulations: various stability fixes (#15198) 
p2p/simulations: introduce dialBan

- Refactor simulations/network connection getters to support
  avoiding simultaneous dials between two peers If two peers dial
  simultaneously, the connection will be dropped to help avoid
  that, we essentially lock the connection object with a
  timestamp which serves as a ban on dialing for a period of time
  (dialBanTimeout).

- The connection getter InitConn can be wrapped and passed to the
  nodes via adapters.NodeConfig#Reachable field and then used by
  the respective services when they initiate connections. This
  massively stablise the emerging connectivity when running with
  hundreds of nodes bootstrapping a network.

p2p: add Inbound public method to p2p.Peer

p2p/simulations: Add server id to logs to support debugging
in-memory network simulations when multiple peers are logging.

p2p: SetupConn now returns error. The dialer checks the error and
only calls resolve if the actual TCP dial fails.
