* mod_auth_internal_{plain,hashed}: Use constant-time string comparison for ↵Matthew Wild2021-05-102-3/+5
| | | | secrets
* util.xmppstream: Reduce default xmppstream limit to 1MBMatthew Wild2021-05-101-1/+1
|
* util.set: Add is_set() to test if an object is a setMatthew Wild2021-05-101-2/+8

* util.hashes: Add constant-time string comparison (binding to CRYPTO_memcmp)Matthew Wild2021-05-101-0/+14

* mod_c2s, mod_s2s, mod_component, mod_bosh, mod_websockets: Set default ↵Matthew Wild2021-05-075-5/+7
| | | | | | | | | | | | stanza size limits c2s/bosh/ws streams will default to 256KB, s2s and components to 512KB. These values are aligned with ejabberd's default settings, which should reduce issues related to inconsistent size limits between servers on the XMPP network. The previous default (10MB) is excessive for any production server, and allows significant memory usage by even unauthenticated sessions.
* util.startup: Set more aggressive defaults for GCMatthew Wild2021-05-071-1/+7
| | | | | | | | | Testing has demonstrated that the default GC parameters are not sufficient to prevent runaway memory growth when running under Lua 5.2 and Lua 5.3. Setting the GC speed to 500 was tested on Lua versions 5.1->5.4 and did not display unbounded memory growth.
* prosodyctl: check config: Add 'gc' to list of global optionsMatthew Wild2021-04-301-1/+1

* mod_saslauth: Use a defined SASL errorKim Alvefur2021-03-181-1/+1
|
* mod_saslauth: Improve code styleKim Alvefur2021-03-181-1/+3
| | | | | | This many returns deserve their own line. `session["sasl_handler"]` style isn't used anywhere else.
* mod_c2s: Log about missing conn on async state changesKim Alvefur2021-03-181-0/+4
|
* mod_c2s: Improve code styleKim Alvefur2021-03-181-2/+6
| | | | | We don't use the quoted table indexing style that often, it's not needed here and it's enough to check for falsyness rather than `nil`.
* mod_c2s: Fix traceback in session close when conn is nilKim Alvefur2021-03-171-2/+2
| | | | Unclear how this happens.
* mod_saslauth: Don't throw errors in async code when connections are gonetmolitor2021-03-181-0/+1
| | | | Fixes #1515
* mod_c2s: Don't throw errors in async code when connections are gonetmolitor2021-03-181-2/+2
| | | | Fixes #1507
* mod_http: Restore ip field for requests without proxiesKim Alvefur2021-02-271-2/+2
| | | | | 8603011e51fe optimized out more than just the loop, leaving the .ip field blank when the request wasn't from a proxy.
* mod_http: Fix trusted proxies check (thanks buildbot)Kim Alvefur2021-02-181-1/+1
| | | | | is_trusted_proxy() is only in trunk, I dun goofed when I rebased 8603011e51fe from trunk.
* mod_http: Skip IP resolution in non-proxied caseKim Alvefur2021-02-181-1/+1
| | | | | Skips doing the whole get_ip_from_request() dance if the request isn't from a proxy at all, even if the client sent the header for some reason.
* Tag 0.11.8Kim Alvefur2021-02-150-0/+0
|
* mod_pep: Advertise base pubsub feature (fixes #1632)0.11.8Kim Alvefur2021-02-151-0/+1
| | | | | Noticed while discussing feature discovery in Gajim Thanks lovetox
* util.interpolation: Fix combination of filters and fallback values #1623Kim Alvefur2021-01-251-2/+2
|
* net.adns: Prevent empty packets from being sent on "connect" (fix #1619)Kim Alvefur2021-01-121-0/+5
| | | | Thanks Ge0rG for testing
* net.server_epoll: Fix off-by-one in 2c559953ad41Kim Alvefur2021-01-101-1/+1
| | | | Thanks tmolitor
* util.timer: Ensure timers can't run more than once per tick (fixes #1620)Kim Alvefur2021-01-081-1/+14
| | | | See longer explanation in 2c559953ad41
* net.server_epoll: Ensure timers can't run more than once per tickKim Alvefur2021-01-081-2/+18
| | | | | | | | This makes sure that a timer that returns 0 (or less) does not prevent runtimers() from completing, as well as making sure a timer added with zero timeout from within a timer does not run until the next tick. Thanks tmolitor
* util.stanza: Move misplaced argument to correct placeKim Alvefur2020-12-241-2/+2
| | | | | valid_utf8() takes only one argument, so the false was probably meant to be valid_xml_cdata(text, attribute=false)
* mod_s2s: Fix copypaste mistake in b3ae48362f78Kim Alvefur2020-12-161-1/+1
| | | | | Directly sending something over s2s needs to use sends2s() but the code copied from mod_c2s had .send()
* MUC: Fix logic bug causing unnecessary presence to be sent, fixes #1615 ↵Matthew Wild2020-12-151-2/+2
| | | | (thanks damencho)
* mod_s2s: Prevent whitespace keepalives the stream has been openedKim Alvefur2020-12-101-1/+4
| | | | | | | | | This will result in the stream timing out instead, which is probably correct if the stream has not been opened yet. This was already done for c2s in e69df8093387 Thanks Ge0rG
* mod_saslauth: Only advertise channel binding if a finished message is availableKim Alvefur2020-11-231-1/+1
| | | | In some cases this method returns nothing, unclear why.
* mod_saslauth: Disable 'tls-unique' channel binding with TLS 1.3 (closes #1542)Kim Alvefur2020-11-231-1/+4
| | | | | | | | The 'tls-unique' channel binding is undefined in TLS 1.3 according to a single sentence in parenthesis in Apendix C of RFC 8446 This may trigger downgrade protection in clients that were expecting channel binding to be available.
* util.promise: Use xpcall() for promise function to preserve tracebacksMatthew Wild2020-11-231-1/+1

* util.stanza: Reject ASCII control characters (fixes #1606)Kim Alvefur2020-11-112-1/+10

* mod_pubsub: Fix notification stanza type setting (fixes #1605)Kim Alvefur2020-11-061-1/+1
|
* mod_pubsub: Lower priority of default <body> generatorKim Alvefur2020-11-051-1/+1
| | | | | | | in order to avoid conflict with a handler at the default (0) priority, making it easier to write your own formatting in plugins. this follows the common pattern of default modules having lower priority
* util.dbuffer: Optimize :sub() and :byte()Matthew Wild2020-10-281-4/+26

* util.debug: Fix locals being reported under wrong stack frame in some cases ↵Matthew Wild2020-10-162-1/+94
| | | | (+tests!!)
* Back out changeset 2c1583bb0e0fKim Alvefur2020-10-151-0/+4
| | | | Same reason as 712b2e6a09d9
* Back out 6dde2c9fa272: Doesn't work on Lua 5.1Kim Alvefur2020-10-151-13/+6
|
* util.strbitop: Remove redundant init functionKim Alvefur2020-10-151-4/+0
| | | | | When you have 3 almost identical functions, you tend to edit one and then copypaste. Forgot to remove this line from the other two.
* util.strbitop: Create buffer in the correct size (optimization)Kim Alvefur2020-10-151-6/+13
| | | | | This avoids dynamically growing the buffer as Lua does when luaL_addchar is used, thus saving on realloc calls.
* util.strbitop: Add tests covering basicsKim Alvefur2020-10-151-0/+41
| | | | Also as docs
* util.strbitop: Reformat codeKim Alvefur2020-10-151-9/+9

* net.websocket.frames: Add test for empty frame with MASK and key setMatthew Wild2020-10-151-0/+10

* net.websocket.frames: Use C string XOR implementationKim Alvefur2020-10-142-24/+8

* util.strbitop: Library for bitwise operations on stringsKim Alvefur2019-09-073-2/+93

* net.websocket.frames: Add small test covering xor-maskingKim Alvefur2020-10-141-0/+13
| | | | This is basically a recording of current behavior, to detect changes.
* net.http.server: Don't send Content-Length on 1xx/204 responses, per RFC ↵Matthew Wild2020-10-131-1/+4
| | | | (fixes #1596)
* net.websocket.frames: Read buffer length correctly in Lua 5.1 (fix #1598)Kim Alvefur2020-10-121-3/+3
| | | | | | | COMPAT: The __len metamethod does not work with tables in Lua 5.1. Both strings and util.dbuffer now expose their length as a :len() method.
* util.dbuffer: Expose length as :len() method, like stringsKim Alvefur2020-10-122-0/+2
| | | | Ref #1598
* MUC: Preserve disco 'node' attribute (or lack thereof) in response (fix ↵Kim Alvefur2020-10-071-2/+2
