* Remove redundant clientDiff functionJune McEnroe2021-09-02
|
* Avoid overwriting manual AWAY messagesJune McEnroe2021-08-21
| | | | | | Setting an AWAY message then disconnecting will no longer replace the AWAY message with the default one. Reconnecting continues to always clear AWAY.
* Use seprintf for capListJune McEnroe2021-06-09
|
* Add seprintfJune McEnroe2021-06-09
| | | | | | | | | Based on seprint(2) from Plan 9. I'm not sure if my return value exactly matches Plan 9's in the case of truncation. seprint(2) is described only as returning a pointer to the terminating '\0', but if it does so even in the case of truncation, it is awkward for the caller to detect. This implementation returns end in the truncation case, so that (ptr == end) indicates truncation.
* Support echo-message capabilityJune McEnroe2021-01-24
| | | | | | | Only request it with labeled-response, since it is impossible to correlate messages to clients without. For clients without echo-message, synthesize a label on PRIVMSG/NOTICE/TAGMSG, then filter out received messages with that label.
* Add -o and -t options to trust self-signed certificates 2.2June McEnroe2021-01-11
|
* Add lazy client registration timeoutJune McEnroe2020-11-20
| | | | | | I don't think this is worth adding a configuration option for since real clients will definitely accomplish registration faster than 10s and it's long enough to even type out manually for testing.
* Set client sockets non-blockingJune McEnroe2020-11-16
| | | | | | | | | | | | | | | | | | | | | Except for during writes. This prevents pounce getting blocked on a client sending only a partial TLS record, for example. Writes still need to block because pounce doesn't have a way to resume them. (And it would do so by having a buffer, but sockets already have a send buffer, so what would be the point of that?) I don't think it should be a problem since outside of stateSync, writes only happen when poll returns POLLOUT. I feel like ideally SO_SNDLOWAT would be set to guarantee a full IRC message can always be written on POLLOUT, but since it's actually TLS records being sent, it's not obvious what the size would be. I'm also making an assumption here that tls_read returning TLS_WANT_POLLOUT is unlikely to happen, since I don't actually set pollfd.events based on that. I'm not sure how wanting to resume a tls_read after a POLLOUT could be cleanly handled. I'm just going to hope that if it does happen, the regular poll loop will eventually sort it out...
* Swap localAccept parameter orderJune McEnroe2020-11-14
|
* Make struct Client publicJune McEnroe2020-11-14
|
* Refactor certificate loading and load all certs from config pathsJune McEnroe2020-08-28
|
* Import xdg.c from catgirlJune McEnroe2020-08-24
|
* Implement stub of palaverapp.com capabilityJune McEnroe2020-08-11
| | | | | | This needs to be documented! But the documentation won't make any sense until there's something that can implement the actual functionality of the capability.
* Refactor clientCA and clientSTS as clientCapsJune McEnroe2020-08-10
|
* Say "OpenSSL" in additional permission noticesJune McEnroe2020-08-06
| | | | LibreSSL is "a modified version of that library".
* Remove compat.hJune McEnroe2020-08-01
|
* Use snprintf instead of strlcatJune McEnroe2020-08-01
|
* Rewrite configure script for all platformsJune McEnroe2020-07-24
|
* Add -R blind-req optionJune McEnroe2020-07-06
| | | | | Allows requesting userhost-in-names on freenode, which is available but hidden.
* Add additional permission for linking with LibreSSLJune McEnroe2020-06-08
| | | | https://www.gnu.org/licenses/gpl-faq.en.html#GPLIncompatibleLibs
* Add server send queueing with time intervalJune McEnroe2020-05-11
| | | | | | | | | This addresses pounce getting killed with "Excess flood" when it sends NAMES commands for too many channels when a client connects. These commands, as well as automatic AWAY commands, are by default throttled to 5 per second. Tested on freenode with 36 channels and 200ms interval.
* Replace .mk files with configure scriptJune McEnroe2020-03-01
| | | | Copied and expanded from catgirl.
* Advertise STS policyJune McEnroe2020-02-27
| | | | | Duration is set to INT_MAX since pounce will never accept cleartext connections.
* Set consumer pos with CAP REQ causal.agency/consumer=nJune McEnroe2020-02-27
| | | | | So the spec doesn't say I can use cap values in CAP REQ. But it also doesn't explicitly say I can't.
* Add causal.agency/consumer capabilityJune McEnroe2020-02-27
|
* Send CAP LS 302 to the serverJune McEnroe2020-02-27
|
* Support CAP LS 302 from clientsJune McEnroe2020-02-27
|
* Support cap-notifyJune McEnroe2020-02-27
|
* Support setnameJune McEnroe2020-02-26

* Support labeled-responseJune McEnroe2020-02-26
|
* Support batchJune McEnroe2020-02-26
|
* Support account-tagJune McEnroe2020-02-26
|
* Support message-tagsJune McEnroe2020-02-25
|
* Request server-time from the server and filter tags for clientsJune McEnroe2020-02-25
| | | | | | | | This doesn't yet, but it will break the "robustness principle" according to which a server "SHOULD NOT" assume that a client capable of parsing one tag is capable of parsing all tags. In future, TagCaps will have all other caps that use tags ORed into it, and only if the client supports none of them will tags be filtered out.
* Bump buffer sizes to allow for tagsJune McEnroe2020-02-25
| | | | | I still think this limit is unreasonably large in comparison to 512 for the actual message.
* Implement source address selectionmultiplexd2020-02-18
| | | | | | This commit introduces a '-S' command line option and a "bind" configuration file option for selecting the source address when making outbound TCP connections (similar to the corresponding option in catgirl(1)).
* Add option to set local client CAJune McEnroe2020-01-12
| | | | | | | | | This is a little bit messy. Allows setting either -A or -W or both. Implements SASL EXTERNAL for clients that expect that when connecting with a client certificate. Need to test that reloading still works inside capsicum, since I suspect that rewind call may be blocked.
* Add a vendor capability for passive clientsJune McEnroe2020-01-10
| | | | | | This way things like litterbox can do it automatically without having to be configured with a hyphen-prefixed username, which is usually invalid anywhere else.
* Update source URLJune McEnroe2019-12-24
| | | | Oops, thought I did this already.
* Reference openssl(1) by absolute pathedef2019-11-27
| | | | | This still allows using openssl(1) from PATH, but defaults to using ${LIBRESSL_PREFIX}/bin/openssl.
* Declare globals as extern in headers, and define in source fileMichael Forney2019-11-21
| | | | | | | | | | | | | | | Otherwise, each source file that includes the header gets its own definition, and according to the C standard (C99 6.9p5): > If an identifier declared with external linkage is used in an > expression (other than as part of the operand of a sizeof operator > whose result is an integer constant), somewhere in the entire > program there shall be exactly one external definition for the > identifier Most compilers use the .bss section for zero data, but if it uses .data instead, or if -Wl,--warn-common is used, this will cause a linking error.
* Request NAMES on sync by defaultJune McEnroe2019-11-15
| | | | This inverts the meaning of -N!
* Use struct timeval for sub-second precisionJune McEnroe2019-11-14
|
* Filter multi-prefixJune McEnroe2019-11-14
|
* Filter userhost-in-namesJune McEnroe2019-11-11
| | | | I really want to be writing tests for these functions...
* Filter invite-notifyJune McEnroe2019-11-10
|
* Filter extended-joinJune McEnroe2019-11-10
|
* Rename listen to localJune McEnroe2019-11-10
|
* Remove extended-join and invite-notifyJune McEnroe2019-11-09
| | | | | | | | | | | | The remaining caps only generate new commands which can easily be filtered out when sending to clients so will be in the first pass of support. extended-join is probably safe to pass through unaltered, just causing extraneous parameters on JOIN commands, but maybe not. invite-notify reuses the INVITE command where the invited user is not self.
* Maintain stateCaps and offer them to clientsJune McEnroe2019-11-09
