This changes the challenge resend logic again to use the existing
`ChallengeData` field of `v5wire.Whoareyou` instead of storing a second
copy of the packet in `Whoareyou.Encoded`. It's more correct this way
since `ChallengeData` is supposed to be the data that is used by the ID
verification procedure.
Also adapts the cross-client test to verify this behavior.
Follow-up to #31543
This changes the p2p protocol handlers to delay message decoding. It's
the first part of a larger change that will delay decoding all the way
through message processing. For responses, we delay the decoding until
it is confirmed that the response matches an active request and does not
exceed its limits.
In order to make this work, all messages have been changed to use
rlp.RawList instead of a slice of the decoded item type. For block
bodies specifically, the decoding has been delayed all the way until
after verification of the response hash.
The role of p2p/tracker.Tracker changes significantly in this PR. The
Tracker's original purpose was to maintain metrics about requests and
responses in the peer-to-peer protocols. Each protocol maintained a
single global Tracker instance. As of this change, the Tracker is now
always active (regardless of metrics collection), and there is a
separate instance of it for each peer. Whenever a response arrives, it
is first verified that a request exists for it in the tracker. The
tracker is also the place where limits are kept.
In both `TestSimultaneousRequests` and `TestSameRequestID`, we send two
concurrent requests. The client under test is free to respond in either
order, so we need to handle responses both ways.
Also fixes an issue where some generated blob transactions didn't have
any blobs.

TestBlobTxWithoutSidecar test could run infinitely in case of a client
not requesting the good transaction. This adds a timeout to make the
test fail in this case.

The main purpose of this change is to enforce the version setting when
constructing the blobSidecar, avoiding creating sidecar with wrong/default
version tag.
I added a test for BlockRangeUpdate in #29158 but forgot to enable it.
Here I'm adding two more tests for it. Also applied a small refactoring
to combine calls to `dial()` and `peer()` into a single function, since
these two calls are duplicated in each test.
This PR implements eth/69. This protocol version drops the bloom filter
from receipts messages, reducing the amount of data needed for a sync
by ~530GB (2.3B txs * 256 byte) uncompressed. Compressed this will
be reduced to ~100GB
The new version also changes the Status message and introduces the
BlockRangeUpdate message to relay information about the available history
range.

This ensures that if we receive a blob transaction announcement where we cannot
link the tx to the sidecar commitments, we will drop the sending peer. This check
is added in the protocol handler for the PooledTransactions message.
Tests for this have also been added in the cross-client "eth" protocol test suite.

This is a not-particularly-important "cleanliness" PR. It removes the
last remnants of the `x/exp` package, where we used the `maps.Keys`
function.
The original returned the keys in a slice, but when it became 'native'
the signature changed to return an iterator, so the new idiom is
`slices.Collect(maps.Keys(theMap))`, unless of course the raw iterator
can be used instead.
In some cases, where we previously collect into slice and then sort, we
can now instead do `slices.SortXX` on the iterator instead, making the
code a bit more concise.
This PR might be _slighly_ less optimal, because the original `x/exp`
implementation allocated the slice at the correct size off the bat,
which I suppose the new code won't.
Putting it up for discussion.

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
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.

push to that fork.
`TerminalTotalDifficultyPassed` is removed. `TerminalTotalDifficulty`
must now be non-nil, and it is expected that networks are already

This PR fixes an issue with blob transaction propagation due to the blob
transation txpool rejecting transactions with gapped nonces. The
specific changes are:
- fetch transactions from a peer in the order they were announced to
minimize nonce-gaps (which cause blob txs to be rejected
- don't wait on fetching blob transactions after announcement is
received, since they are not broadcast
Testing:
- unit tests updated to reflect that fetch order should always match tx
announcement order
- unit test added to confirm blob transactions are scheduled immediately
for fetching
- running the PR on an eth mainnet full node without incident so far

This PR adds the `dns:read` and `dns:edit` permissions to the required
set of permissions checked before deploying an ENR tree to Cloudflare.
These permissions are necessary for a successful publish.
**Background**:
The current logic for `devp2p dns to-cloudflare` checks for `zone:edit`
and `zone:read` permissions. However, when running the command with only
these two permissions, the following error occurs:
```
wrong permissions on zone REMOVED-ZONE: map[#zone:edit:false #zone:read:true]
```
Adding `zone:read` and `zone:edit` to the API token led to a different
error:
```
INFO [08-19|14:06:16.782] Retrieving existing TXT records on pos-nodes.hardfork.dev
Authentication error (10000)
```
This suggested that additional permissions were required. I added
`dns:read`, but encountered another error:
```
INFO [08-19|14:11:42.342] Retrieving existing TXT records on pos-nodes.hardfork.dev
INFO [08-19|14:11:42.851] Updating DNS entries
failed to publish REMOVED.pos-nodes.hardfork.dev: Authentication error (10000)
```
Finally, after adding both `dns:read` and `dns:edit` permissions, the
command executed successfully with the following output:
```
INFO [08-19|14:13:07.677] Checking Permissions on zone REMOVED-ZONE

```
With this PR, the required permissions for deploying an ENR tree to
Cloudflare now include `zone:read`, `zone:edit`, `dns:read`, and
`dns:edit`. The initial check now includes all of the necessary
permissions and indicates in the error message which permissions are
missing:
```
INFO [08-19|14:17:20.339] Checking Permissions on zone REMOVED-ZONE

```
enode.Node was recently changed to store a cache of endpoint information. The IP address in the cache is a netip.Addr. I chose that type over net.IP because it is just better. netip.Addr is meant to be used as a value type. Copying it does not allocate, it can be compared with ==, and can be used as a map key.
This PR changes most uses of Node.IP() into Node.IPAddr(), which returns the cached value directly without allocating.
While there are still some public APIs left where net.IP is used, I have converted all code used internally by p2p/discover to the new types. So this does change some public Go API, but hopefully not APIs any external code actually uses.
There weren't supposed to be any semantic differences resulting from this refactoring, however it does introduce one: In package p2p/netutil we treated the 0.0.0.0/8 network (addresses 0.x.y.z) as LAN, but netip.Addr.IsPrivate() doesn't. The treatment of this particular IP address range is controversial, with some software supporting it and others not. IANA lists it as special-purpose and invalid as a destination for a long time, so I don't know why I put it into the LAN list. It has now been marked as special in p2p/netutil as well.
Here we clean up internal uses of type discover.node, converting most code to use
enode.Node instead. The discover.node type used to be the canonical representation of
network hosts before ENR was introduced. Most code worked with *node to avoid conversions
when interacting with Table methods. Since *node also contains internal state of Table and
is a mutable type, using *node outside of Table code is prone to data races. It's also
cleaner not having to wrap/unwrap *enode.Node all the time.
discover.node has been renamed to tableNode to clarify its purpose.
While here, we also change most uses of net.UDPAddr into netip.AddrPort. While this is
technically a separate refactoring from the *node -> *enode.Node change, it is more
convenient because *enode.Node handles IP addresses as netip.Addr. The switch to package
netip in discovery would've happened very soon anyway.
The change to netip.AddrPort stops at certain interface points. For example, since package
p2p/netutil has not been converted to use netip.Addr yet, we still have to convert to
net.IP/net.UDPAddr in a few places.
Node discovery periodically revalidates the nodes in its table by sending PING, checking
if they are still alive. I recently noticed some issues with the implementation of this
process, which can cause strange results such as nodes dropping unexpectedly, certain
nodes not getting revalidated often enough, and bad results being returned to incoming
FINDNODE queries.
In this change, the revalidation process is improved with the following logic:
- We maintain two 'revalidation lists' containing the table nodes, named 'fast' and 'slow'.
- The process chooses random nodes from each list on a randomized interval, the interval being
faster for the 'fast' list, and performs revalidation for the chosen node.
- Whenever a node is newly inserted into the table, it goes into the 'fast' list.
Once validation passes, it transfers to the 'slow' list. If a request fails, or the
node changes endpoint, it transfers back into 'fast'.
- livenessChecks is incremented by one for successful checks. Unlike the old implementation,
we will not drop the node on the first failing check. We instead quickly decay the
livenessChecks give it another chance.
- Order of nodes in bucket doesn't matter anymore.
I am also adding a debug API endpoint to dump the node table content.

Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths.
Package path implements utility routines for manipulating slash-separated paths.
The path package should only be used for paths separated by forward slashes, such as the paths in URLs
Improving two things here:
On hive, where we look at these tests, the Go code comment above the test
is not visible. When there is a failure, it's not obvious what the test is actually
expecting. I have converted the comments in to printed log messages to
explain the test more.
Second, I noticed that besu is failing some tests because it happens to request
a header when we want it to send transactions. Trying the minimal fix here to
serve the headers.
