Original motivation was tiresome warnings about Lua 5.4 not being
supported yet.
Can still be handy to tweak log level, e.g. to prevent logging to
interfere with command output.

Doesn't affect normal usage by Prosody since neither A nor AAAA records
use this and SRV records has the host name last so the position is not
needed.

Note the duplicate 9 and 16 entries, neither of which are especially
relevant for our resolver usage.

Goal is to regenerate this file from the IANA registry using a tool.
Having it in a separate file will reduce vcs noise in util.dns

Probably worked anyway but settings might not always have been applied
depending on what order things happens in.
Error was hidden by the pcall, which was sorta intentional...

We break the SHOULD about the merged _xmpp and _xmpps SRV handling, but
we follow all the MUSTs

When there are no records to return the return value from dns.lookup()
might be nil or might be a table containing zero records, depending on
which DNS library is used

It is unexpected that 'example.com' matches 'exampleicom.org' and this
use of Lua patterns is undocumented and unlikely to be widely known or
used.

The Lua string.format %q doesn't behave correctly for all characters
that should be escaped in a quoted-string. And who knows what effects
higher Unicode might have here.
Applying percent-encoding of filenames seems like the safest way to deal
with filenames, as well as being easier than implementing the actual
quoted-string transform, which seems complicated and I'm not even sure
it covers every possible character.
Filenames can safely be assumed to be UTF-8 since they are passed in an
attribute in the query without any escaping.

Stops an error when extra_labels is nil since it attempts to index it

It's what `gwl` in my vim did. Must be optimal then.

Fixes that a multi-line string ended up "like\
\9this" instead of "like\nthis" as can be demonstrated by somehow
initiating a connection to a HTTP server.
|
|
|
|
|
| |
This should ensure any certificate needed for HTTP services will also be
included in the certificate import.

Since XEP-0363 is essentially mandatory now this will hopefully help
diagnose some common issues.

Shortest first, then alphabetically, so that it prefers the base domain
over subdomains.
Fixes that it might otherwise pick a random sub-domain for filename on
each run, cluttering the certs directory and potentially tricking
Prosody into using an older certificate that might be about to expire.

Enables generation of summaries for more than Atom without additional

Allows using different ones even if multiple semantically different
formats share the same root element xmlns, e.g. generic Atom and
XEP-0277 entries.

Relevant and sometimes needed for Direct TLS which mod_s2s uses this
context for. Primarily when e.g. mod_net_multiplex or equivalent ALPN
based dispatch is used.
All these contexts should likely move away from mod_tls and into either
mod_s2s or portmanager. The later already duplicates some of this work.

As in the argument to user:create() and user:roles()
Tricky to come up with something sensible to write when Prosody core
only knows of the 'prosody:admin' role so far.
|
|
|
|
|
|
|
|
|
|
| |
So that the same TLS context is used for both Direct TLS and starttls,
since they are supposed to be functionally identical apart from the few
extra round trips.
A new event is added because the 's2s-created' event fires much later,
after a connection has already been established, where we need the TLS
context before that.
|
|
|
|
|
|
|
|
|
|

Makes it faster by cutting out the roundtrips involved in <starttls/>,
at the cost of making an additional SRV lookup.
Since we already ignore a missing <starttls/> offer and try anyway there
is not much difference in security. The fact that XMPP is used and the
hostnames involved might still be visible until the future Encrypted
ClientHello extension allows hiding those too.
|
|
|
|
|
|
| |
Only allowing it to be passed directly makes it hard to combine plain
(i.e. starttls) and Direct TLS connections in the same connection
resolution procedure. But now we can, using chained resolvers!
|
|
|
|
| |
Say if you wanted to try both _xmpp and _xmpps services

Makes the code more like util.xmppstream, allowing easier comparisons if
we ever need to apply fixes in the future.

LuaExpat uses a registry reference to track handlers, which makes
it so that an upvalue like this creates a reference loop that keeps the
parser and its handlers from being garbage collected. The same issue has
affected util.xmppstream in the past.
Code for checking:
local xml_parse = require"util.xml".parse;
for i = 1, 10000 do xml_parse("<root/>") end
collectgarbage(); collectgarbage();
print(collectgarbage("count"), "KiB");
A future release of LuaExpat may fix the underlying issue there.

Yes. This is as bad as it sounds. CVE pending.
In Prosody itself, this only affects mod_websocket, which uses util.xml
to parse the <open/> frame, thus allowing unauthenticated remote DoS
using Billion Laughs. However, third-party modules using util.xml may
also be affected by this.
This commit installs handlers which disallow the use of doctype
declarations and processing instructions without any escape hatch. It,
by default, also introduces such a handler for comments, however, there
is a way to enable comments nontheless.
This is because util.xml is used to parse human-facing data, where
comments are generally a desirable feature, and also because comments
are generally harmless.

Debugging a case where certs are not imported correctly but prosodyctl
still reports success. Hoping this will shed some light on it.

Prevents potential weirdness in case there's any %s or such in a host,
file or directory name, since show_warning() is printf().

This tool hasn't been updated for recent XEP-0227 changes, hasn't seen
many changes at all since its introduction and I don't remember anyone
mentioning ever using it.
Using mod_storage_xmlarchive and the migrator or the 3rd party
mod_migrate tool should work better these days and should be the way
forward.
