Nagle increases latency and is the bane of all networking!

Activated by setting config.tcp_keepalive to a number, in seconds.
Defaults to 2h.
Depends on LuaSocket support for this option.

In case one wishes to enable this for all connections, not just c2s
(not Direct TLS ones, because LuaSec) and s2s. Unclear what use these
are, since they kick in after 2 hours of idle time.

Good to know if it fails, especially since the return value doesn't seem
to be checked anywhere.
Since LuaSec-wrapped sockets don't expose the setoption method, this
will likely show when mod_c2s tries to enable keepalives on direct tls
connections.

Couldn't use those with the host being deactivated.
Problem: This kicks in on reload, which isn't needed.

Increases log level for stream conditions that could indicate a problem
on our end, especially programming errors like invalid XML, or the
remote server saying that our certificate is invalid, since these should
be investigated.
Non-issues like closing of idle streams are lowered to debug since it's
mostly noise.
Other issues left at info are mostly about changes to the remote server,
e.g. complete or partial shutdown.

Reduces the number of left-over timers to handle after many s2s
connections were started, leaving only the ones related to incomplete
connections.

Skips a roundtrip through the main loop in case client-first data is
available already, if not then :onreadable() will set the appropriate
timeout.

There's the theory that the socket isn't the same before/after wrap(),
but since epoll operates on FD numbers this shouldn't matter.
|
| | |
| |
| |
| | |
The :init() method sets a different timeout than the TLS related methods.
|
| | |
| |
| |
| |
| |
| | |
Since TLS is a client-first protocol there is a chance that the
ClientHello message is available already. TLS Fast Open and/or the
TCP_DEFER_ACCEPT socket option would increase that chance.

So there's :startls(), :inittls() and :tlshandshake()
:starttls() prepares for plain -> TLS upgrade and ensures that the
(unencrypted) write buffer is drained before proceeding.
:inittls() wraps the connection and does things like SNI, DANE etc.
:tlshandshake() steps the TLS negotiation forward until it completes

This should probably never happen, but probably does anyways.
A debug message would show the truth of the matter.

Nicer to get rid of a conditional that covers such a large portion of a
pretty big function.
|
| | |
| |
| |
| |

These direct accesses are probably more optimized, but weird when the
module API has methods for these things.

Allows testing e.g. opportunistic writes or other settings easily in CI
or otherwise without editing the config file.
make integration-test PROSODY_NETWORK_SETTINGS='{"opportunistic_writes":true}'
|
| | |
| |
| |

| |

To make it easier to test select and event without having to edit the
config file, e.g. in CI.
make integration-test PROSODY_NETWORK_BACKEND=event

net.http.files serving a big enough file on a fast enough connection
with opportunistic_writes enabled could trigger a stack overflow through
repeatedly serving more data that immediately gets sent, draining the
buffer and triggering more data to be sent. This also blocked the server
on a single task until completion or an error.
This change prevents nested opportunistic writes, which should prevent
the stack overflow, at the cost of reduced download speed, but this is
unlikely to be noticeable outside of Gbit networks. Speed at the cost of
blocking other processing is not worth it, especially with the risk of
stack overflow.

It isn't quite an error.

When opportunistic writes are enabled this reduces the number of
syscalls and TCP packets sent on the wire.
Experiments with TCP Fast Open made this even more obvious.
That table trick probably wasn't as efficient. Lua generates bytecode
for a table with zero array slots and space for two entries in the hash
part, plus code to set [2] and [4]. I didn't verify but I suspect it
would have had to resize the table when setting [1] and [3], although
probably only once. Concatenating the strings directly in Lua is easier
to read and involves no extra table or function call.

This may speed up client-first protocols (e.g. XMPP, HTTP and TLS) when
the first client data already arrived by the time we accept() it.
If LuaSocket supported TCP_DEFER_ACCEPT we could use that to further
increase the chance that there's already data to handle.
In case no data has arrived, no harm should be done, :onreadable would
simply set the read timeout and we'll get back to it once there is
something to handle.

The :init method is more suited for new outgoing connections, which is
why it uses the connect_timeout setting.
Depending on whether a newly accepted connection is to a Direct TLS port
or not, it should be handled differently, and was already. The :starttls
method sets up timeouts on its own, so the one set in :init was not needed.
Newly accepted plain TCP connections don't need a write timeout set, a
read timeout is enough.
|

This should make sure that if there's data left to be written when
closing a connection, there's also a timeout so that it doesn't wait
forever.

Things can behave unexpectedly when fed ANSI escape codes.

In some cases you might end up with both 'xmpp.example.com' and
'xmpp.example.com.', which are the same thing so no point in doing the
same checks twice.

Clients would try to connect and receive an error or timeout, increasing
the time it takes to establish a connection. Probably not what you want.
If you really want IPv6 or IPv4 disabled, best remove the A or AAAA record.
|

| |
| |

Why would you do this?!

If you set 'use_ipv4 = false' then you probably don't care much for the
host not resolving to the IPv4 address, and same with 'use_ipv6'.

This may have mistakenly caused link-local addresses to be considered
global. May have caused mod_s2s and prosodyctl check dns to behave
incorrectly on networks using link-local IPv4 addresses. By my
guesstimate, these are extremely rare. Probably minimal impact beyond
a bit longer to establish s2s and some possible confusion from
prosodyctl check dns results.

This should a) prevent injection of text that looks like legitimate log
lines and b) not mangle tracebacks.

Made the pattern match a longer range than intended, but with no effect
since those characters are not present in the 'control_symbols' table.

If unbound was initialized prior to this then the config change here
wouldn't apply, and it will again think that 127.0.1.1 has been found
in DNS.

This replaces an earlier method in a private extension that logged
pretty-printed XML, which broke due to the escaping added in util.format
