| * util.bit53: Add left- and right shift operationsKim Alvefur2021-06-281-0/+2
| | | | | | | | | | While not used by anything in Prosody, it is known to be used by some 3rd party modules.
| * util.prosodyctl: check turn: New command to verify STUN/TURN service is ↵Matthew Wild2022-03-041-2/+163
| | | | | | | | operational
| * util.hex: Deprecate to/from in favour of encode/decode, for consistency!Matthew Wild2022-03-044-4/+8
| |
| * core.certmanager: Turn soft dependency on LuaSec into a hardKim Alvefur2022-02-101-1/+1
| | | | | | | | | | | | The default network backend server_epoll already requires LuaSec so Prosody won't even start without it, so we can get rid of these lines here too.
* | prosodyctl: check dns: Allow admin to specify undiscoverable external IPs in ↵Matthew Wild2022-03-021-0/+5
| | | | | | | | config
* | prosodyctl: check dns: List discovered addresses for diagnostic purposesMatthew Wild2022-03-021-0/+16
| | | | | | | | | | | | It is very common to get the "unknown address" warning with this command, but people do not always understand it, or know how to debug it. Now we clearly show the addresses that prosodyctl discovered.
* | util.prosodyctl: check: warn about unreferenced components, suggest disco_itemsMatthew Wild2022-03-021-0/+35
| |
* | util.prosodyctl: Warn about enabled public registration in 'check config'Matthew Wild2022-03-021-0/+28
| |
* | util.async: Optionally allow too many 'done' callbacksKim Alvefur2022-02-221-2/+2
|/ | | | | Sometimes, like in mod_c2s and mod_s2s during shutdown, all you want is to wait for the first done() and not complicate things.
* prosody: Move last cleanup and shutdown code into util.startupKim Alvefur2019-01-011-0/+16
|
* util.dns: Remove compat for pre-0.11 lack of inet_ntop bindingKim Alvefur2022-02-151-32/+3
| | | | The inet_ntop binding was added in 8b612ec00e4a and included in 0.11.0
* util.dns: Replace base16 implementation with util.hexKim Alvefur2022-02-151-10/+1
| | | | Less code!
* util.dependencies: Refer to 'apt' instead of 'apt-get'Kim Alvefur2022-02-131-6/+6
| | | | | The more modern and user friendly frontend, should be in every supported version of Debian and Ubuntu by now
* util.startup: Enable DANE in http client library with use_daneKim Alvefur2022-02-051-0/+1
|
* util.xml: Add an option to allow <?processing instructions?>Kim Alvefur2022-02-041-1/+4
| | | | | These should generally be safe to just ignore, which should be the default behavior of Expat and LuaExpat
* util.format: Fix typo in comment [codespell]Kim Alvefur2022-02-041-1/+1
|
* Revert util.debug change accidentally committed in e157e5c79daaMatthew Wild2022-02-041-1/+1
|
* util.pluginloader: Fix method to return any module metadata (luacheck)Matthew Wild2022-02-041-1/+1
|
* util.pluginloader: Support for a per-file load filterMatthew Wild2022-02-031-6/+14
| | | | | Load filters can choose to block the loading of certain files, and optionally return some metadata about the loaded file.
* util.pluginloader: Support for multiple pluginloader instances, and optionsMatthew Wild2022-02-032-11/+29
|
* util.startup: Teach prosodyctl to be completely --silentKim Alvefur2021-11-281-0/+3
|
* util.startup: Teach prosodyctl to be --quiet as complement to --verboseKim Alvefur2021-11-281-1/+7
| | | | | | | | 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.
* util.dns: Minor updates of SVCB parserKim Alvefur2022-02-021-1/+2
| | | | Now based on draft-ietf-dnsop-svcb-https-08
* util.dns: Implement SVCB record parserKim Alvefur2020-10-041-0/+54
| | | | Based on draft-ietf-dnsop-svcb-https-00
* util.dns: Fix returning read position after zero-length nameKim Alvefur2020-10-041-1/+1
| | | | | | 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.
* util.dnsregistry: Regenerate from IANA registryKim Alvefur2022-02-021-57/+120
| | | | | Note the duplicate 9 and 16 entries, neither of which are especially relevant for our resolver usage.
* util.dns: Move DNS parameters details into util.dnsregistryKim Alvefur2020-10-042-56/+63
| | | | | 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
* util.prosodyctl.check: Fix reset of libunbound before DNS checksKim Alvefur2022-02-011-1/+1
| | | | | | | 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...
* util.prosodyctl.check: Fix A/AAAA check for proxy65 and httpKim Alvefur2022-01-301-2/+2
| | | | | | 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
* util.prosodyctl.check: Include multiplexed ports in DNS checks #1704Kim Alvefur2022-01-301-0/+13
|
* util.format: Expand explanation of purpose in commentsKim Alvefur2022-01-271-1/+6
|
* util.format: Skip control code escaping when doing full serializationKim Alvefur2022-01-271-1/+1
| | | | | | 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.
* util.prosodyctl.cert: Look for certs matching 'http_host'Kim Alvefur2022-01-271-0/+4
| | | | | This should ensure any certificate needed for HTTP services will also be included in the certificate import.
* util.prosodyctl.check: Fix use of LuaSocket URL parserKim Alvefur2022-01-271-1/+1
|
* util.prosodyctl.check: Add HTTP related DNS checksKim Alvefur2022-01-271-8/+41
| | | | | Since XEP-0363 is essentially mandatory now this will hopefully help diagnose some common issues.
* util.prosodyctl.cert: Look for certificates in a consistent orderKim Alvefur2022-01-261-0/+9
| | | | | | | | | 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.
* util.xtemplate: Yet another string template libraryKim Alvefur2022-01-241-0/+86
| | | | | | This one takes a stanza as input Roughly based on util.interpolation

| * util.xml: Deduplicate handlers for restricted XML0.11.13Kim Alvefur2022-01-201-12/+5
| | | | | | | | | | Makes the code more like util.xmppstream, allowing easier comparisons if we ever need to apply fixes in the future.
| * util.xml: Break reference to help the GC (fix #1711)Kim Alvefur2022-01-201-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * util.xml: Do not allow doctypes, comments or processing instructions0.11.12Jonas Schäfer2022-01-101-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | util.prosodyctl.cert: Check success of copy operations, warn on failKim Alvefur2022-01-191-4/+9
| | | | | | | | | | Debugging a case where certs are not imported correctly but prosodyctl still reports success. Hoping this will shed some light on it.
* | util.prosodyctl.cert: Pass variables via formatting instead of concatenationKim Alvefur2022-01-191-5/+5
| | | | | | | | | | Prevents potential weirdness in case there's any %s or such in a host, file or directory name, since show_warning() is printf().
* | util.jid: Explicitly check for nil rather than falsyKim Alvefur2022-01-151-14/+14
| | | | | | | | A boolean false should blow up.
* | util.xml: Do not allow doctypes, comments or processing instructionsJonas Schäfer2022-01-101-2/+23

* | util.prosodyctl.cert: Fix boolean logic bugKim Alvefur2022-01-091-1/+1
| | | | | | | | | | | | | | Boolean logic, never correct on the first try. We want to skip copying the same cert if it _has_ been imported already, not if it has not.
* | util.startup: Allow supplying an argument parsing settingsKim Alvefur2022-01-091-2/+2
| | | | | | | | | | | | The 'prosody' global is not global this early so there was no way to override the process type field or argument parsing settings from outside, e.g. from the migrator.
* | util.prosodyctl.check: Parameterize replacement instructionsKim Alvefur2022-01-081-11/+25
| | | | | | | | | | This ought to make it easier to translate in the future. And easier to reword, now!
