The diagnostic tool was saving the unencrypted version of the messages, which is an obvious
security flaw. As of this commit:
* encrypted messages saved instead of plain text.
* all messages are stored, even that created by the user of wnode.
This is in preparation for the switch to libp2p: the ID generated
will be from a private key created with the help of libp2p's crypto
library, while Whisper will still use Go's default crypto libraries
for encrypting its messages. This change removes a conflict.
It shouldn't have any impact as the person receiving emails is
the user, not the node.
* cmd,node,rpc: add allowedHosts to prevent dns rebinding attacks
* p2p,node: Fix bug with dumpconfig introduced in r54aeb8e4c0bb9f0e7a6c67258af67df3b266af3d
* rpc: add wildcard support for rpcallowedhosts + go fmt
* cmd/geth, cmd/utils, node, rpc: ignore direct ip(v4/6) addresses in rpc virtual hostnames check
* http, rpc, utils: make vhosts into map, address review concerns
* node: change log messages to use geth standard (not sprintf)
* rpc: fix spelling
* p2p: add DialRatio for configuration of inbound vs. dialed connections
* p2p: add connection flags to PeerInfo
* p2p/netutil: add SameNet, DistinctNetSet
* p2p/discover: improve revalidation and seeding
This changes node revalidation to be periodic instead of on-demand. This
should prevent issues where dead nodes get stuck in closer buckets
because no other node will ever come along to replace them.
Every 5 seconds (on average), the last node in a random bucket is
checked and moved to the front of the bucket if it is still responding.
If revalidation fails, the last node is replaced by an entry of the
'replacement list' containing recently-seen nodes.
Most close buckets are removed because it's very unlikely we'll ever
encounter a node that would fall into any of those buckets.
Table seeding is also improved: we now require a few minutes of table
membership before considering a node as a potential seed node. This
should make it less likely to store short-lived nodes as potential
seeds.
* p2p/discover: fix nits in UDP transport
We would skip sending neighbors replies if there were fewer than
maxNeighbors results and CheckRelayIP returned an error for the last
one. While here, also resolve a TODO about pong reply tokens.
The bulk of the issue was to adapt to the new requirement
that a v6 filter has to either contain a symmertric key or
an asymmetric one.
This commits revert one of the fixes that I made to remove
a linter warning: unexporting NewSentMessage. This is not
really a problem as I have a cleanup in the pipe that will
solve this issue.
* whisper: fixes warnings from the code linter
* whisper: more non-API-breaking changes
The remaining lint errors are because of auto-generated
files and one is because an exported function has a non-
exported return type. Changing this would break the API,
and will be part of another commit for easier reversal.
* whisper: un-export NewSentMessage to please the linter
This is an API change, which is why it's in its own commit.
This change was initiated after the linter complained that
the returned type wasn't exported. I chose to un-export
the function instead of exporting the type, because that
type is an implementation detail that I would like to
change in the near future to make the code more
readable and with an increased coverage.
* whisper: update gencodec output after upgrading it to new lint standards
This commit affects p2p/discv5 "topic discovery" by running it on
the same UDP port where the old discovery works. This is realized
by giving an "unhandled" packet channel to the old v4 discovery
packet handler where all invalid packets are sent. These packets
are then processed by v5. v5 packets are always invalid when
interpreted by v4 and vice versa. This is ensured by adding one
to the first byte of the packet hash in v5 packets.
DiscoveryV5Bootnodes is also changed to point to new bootnodes
that are implementing the changed packet format with modified
hash. Existing and new v5 bootnodes are both running on different
ports ATM.
This commit:
- Adds a --msgfile option to read the message to sign from a file
instead of command line argument.
- Adds a unit test for signing subcommands.
- Removes some weird whitespace in the code.
* dashboard: footer, deep state update
* dashboard: resolve asset path
* dashboard: remove bundle.js
* dashboard: prevent state update on every reconnection
* dashboard: fix linter issue
* dashboard, cmd: minor UI fix, include commit hash
* remove geth binary
* dashboard: gitCommit renamed to commit
* dashboard: move the geth version to the right, make commit optional

* common/fdlimit: Move fdlimit files to separate package
When go-ethereum is used as a library the calling program need to set
the FD limit.
This commit extract fdlimit files to a separate package so it can be
used outside of go-ethereum.
* common/fdlimit: Remove FdLimit from functions signature
* common/fdlimit: Rename fdlimit functions
