* Remove bad assertJune McEnroe2020-02-18
| | | | | If there's no room left in the buffer, tls_read will return 0 (since we gave it zero length to read into) and cause client->error to be set.
* 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.
* Intercept client QUIT with no parameter 1.0p3June McEnroe2019-12-28
| | | | Oops! Clients could get pounce to quit if they didn't send a message.
* Don't send self-PMs to the server 1.0p2June McEnroe2019-12-08

* Fix wordcmp return value when the words have differing lengthsMichael Forney2019-11-21
| | | | | | | | | | Otherwise, the result of strncmp gets converted size_t, since size_t has greater rank than int. Since wordcmp is only ever used as a boolean condition, this poses no real issue, but presumably, it is meant to behave like the other *cmp function and return a value less than, equal to, or greater than 0 depending on the result of the comparison.
* 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.
* client: Include time.h for gmtime and strftimeMichael Forney2019-11-20
|
* Format milliseconds as intJune McEnroe2019-11-20
| | | | | I don't know what I was thinking. I'm expecting a number less than 1000 of course that fits in int.
* Add concept of passive clientsJune McEnroe2019-11-14
|
* Use struct timeval for sub-second precisionJune McEnroe2019-11-14
|
* Remove server-time filter TODOJune McEnroe2019-11-14
| | | | | I think it's fine to keep it separate since it's a core function of the bouncer.
* Tweak filter regexesJune McEnroe2019-11-14
|
* Filter multi-prefixJune McEnroe2019-11-14
|
* Replace filters with regex replacesJune McEnroe2019-11-14
|
* Refactor filterUserhostInNamesJune McEnroe2019-11-13
|
* Factor out wordcpy for filtersJune McEnroe2019-11-13
|
* Skip initial NAMES parametersJune McEnroe2019-11-11
| | | | | | | Channel names can contain '!' so splitting the whole message on it won't work. I hate this code though.
* Filter userhost-in-namesJune McEnroe2019-11-11
| | | | I really want to be writing tests for these functions...
* Compare words without copying in filtersJune McEnroe2019-11-10
|
* Filter invite-notifyJune McEnroe2019-11-10
|
* Filter extended-joinJune McEnroe2019-11-10
|
* Filter ACCOUNT, AWAY, CHGHOST for incapable clientsJune McEnroe2019-11-10
|
* Maintain stateCaps and offer them to clientsJune McEnroe2019-11-09
|
* Parse capabilitiesJune McEnroe2019-11-09
| | | | | | The list that I've defined are the ones that I expect to be able to enable probably without any clients breaking... And of course server-time which pounce implements itself.
* Define macro for bit flag enumsJune McEnroe2019-11-09
|
* Only change AWAY status for registered clientsJune McEnroe2019-11-08
| | | | | | Turns out I did eventually fix this, because I may want to implement "passive clients" for logging or notification stuff, which wouldn't affect AWAY status either.
* Use #defines for constant stringsJune McEnroe2019-11-06
| | | | | GCC hates declaring static consts in headers and not using them, for some stupid reason.
* Change license to GPLv3June McEnroe2019-11-06
| | | | | | | | | | | | | | > Notwithstanding any other provision of this License, if you modify the > Program, your modified version must prominently offer all users > interacting with it remotely through a computer network (if your version > supports such interaction) an opportunity to receive the Corresponding > Source of your version by providing access to the Corresponding Source > from a network server at no charge, through some standard or customary > means of facilitating copying of software. This potentially means that every freenode user, for example, is interacting with this software, and offering the corresponding source to each of them is an unreasonable burden.
* Use explicit_bzero from LibreSSLJune McEnroe2019-11-06
|
* Zero PASS parameterJune McEnroe2019-11-04
|
* Hash client passwords with cryptJune McEnroe2019-11-04
|
* Use explicit_bzero to clear passwordsJune McEnroe2019-10-31
| | | | | GNU doesn't implement memset_s, but both FreeBSD and GNU implement explicit_bzero. Darwin doesn't, so #define it in terms of memset_s.
* Shrink client buffer sizeJune McEnroe2019-10-31
| | | | | | | Clients are generally not going to send huge amounts at a time, and IRC messages are limited to 512 bytes. If in the future we supported message tags from clients, which have a size limit of 8191 bytes, this would unfortunately have to be set much higher.
* Specify when command is allowed in Handlers listJune McEnroe2019-10-28
|
* Disallow PRIVMSG/NOTICE before registrationJune McEnroe2019-10-28
|
* Move entire login flow to state and reorganize itJune McEnroe2019-10-28
|
* Only increment consumer after successful sendJune McEnroe2019-10-27
|
* Improve client/server error messagesJune McEnroe2019-10-27
|
* Drop clients on zero-length readsJune McEnroe2019-10-27
|
* Require PASS before USERJune McEnroe2019-10-26
| | | | Prevent creating a ring consumer without authentication.
* OopsJune McEnroe2019-10-26
|
* Disconnect client on unknown commandJune McEnroe2019-10-26
| | | | | During registration, no other commands should be sent. Afterwards, only intercepted commands will get parsed.
* Add AGPLv3 notice on client registrationJune McEnroe2019-10-25
| | | | OwO
* Send PRIVMSG and NOTICE to other clientsJune McEnroe2019-10-25
|
* Clean up clientJune McEnroe2019-10-25
|
* Use produce/consume words for ring bufferJune McEnroe2019-10-25
| | | | To disambiguate clientRecv and clientRead, say clientConsume.
* Implement client reading from ring bufferJune McEnroe2019-10-25
| | | | It's still messy but it works!!
* Zero entire Client structJune McEnroe2019-10-24
| | | | | Does zeroing that extra 4K really matter? I'd rather not have uninitialized reads.
* Register readers by client usernamesJune McEnroe2019-10-24
