* 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.
* 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.
* 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)).
* Use Xr for the first "pounce" in README 1.1June McEnroe2020-01-17

* Add litterbox to READMEJune McEnroe2020-01-17
|
* Rename SASL EXTERNAL section to CertFPJune McEnroe2020-01-17
|
* Document process of generating client certificatesJune McEnroe2020-01-17
|
* Set certificate expiry to 10 yearsJune McEnroe2020-01-16
| | | | | I'm pretty sure any kind of "renewing" of these is going to suck, so just set it long enough that the world will probably be ash by then.
* Allow signing by CA in -gJune McEnroe2020-01-12
|
* Clean up documentation for -AJune McEnroe2020-01-12
|
* Rename all local-related options to local-June McEnroe2020-01-12
| | | | | | | This disambiguates client-ca and client-pass from client-cert and client-key, which apply to opposite sides of the program. The old option names will continue to work.
* Use the CAP_PREAD rightJune McEnroe2020-01-12
| | | | Required for the rewind call when loading the CA.
* 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.
* Rename -A and -Q to -y and -qJune McEnroe2020-01-07
| | | | | | | | | | | The other upper-case options are related to the listening side of things, not the server side, so this is more consistent. This is incompatible, but will fail loudly, and I expect these options are more likely set in a configuration file, if they are set at all. I also want to free up -A for setting a client CA, but assuming your away message is not also an existing file path, that will continue to fail loudly.
* 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.
* Update source URLJune McEnroe2019-12-24
| | | | Oops, thought I did this already.
* Exit on zero-length server readJune McEnroe2019-12-22
|
* Revert "Exit when server gets POLLHUP"June McEnroe2019-12-22
| | | | | | | Turns out the more likely thing is that the fd will just continue to be POLLIN and produce zero-length reads. This reverts commit 5707b15920a1ce57f01db0d592487d833218be9d.
* Exit when server gets POLLHUPJune McEnroe2019-12-20
| | | | | | This should maybe gracefully inform clients of what happened, but for now this is much better than the infinite poll loop that happened previously.
* Add CONTRIBUTING section to READMEJune McEnroe2019-12-17
|
* Don't send self-PMs to the server 1.0p2June McEnroe2019-12-08
|
* Reference openssl(1) by absolute pathedef2019-11-27
| | | | | This still allows using openssl(1) from PATH, but defaults to using ${LIBRESSL_PREFIX}/bin/openssl.
* Simplify Linux.mkJune McEnroe2019-11-27
| | | | | This should just be what is definitely necessary, and all distros have their own problems. This works on Void Linux at least.
* Don't always create ${ETCDIR}/rc.dJune McEnroe2019-11-26
|
* Link calico with libcrypto on Linux 1.0p1June McEnroe2019-11-21
| | | | For the strlcpy implementation.
* 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.
* Zero temporary SASL PLAIN bufferJune McEnroe2019-11-21
|
* Use a static buffer for plainBase64June McEnroe2019-11-21
|
* Use a fixed buffer size for SASL PLAIN authenticationMichael Forney2019-11-21
| | | | | | | handleAuthenticate only sends a single AUTHENTICATE message, so according to https://ircv3.net/specs/extensions/sasl-3.1.html, its maximum length is 399. So, we know that the authentication string can be at most 299 bytes.
* Avoid a couple VLAs with constant sizeMichael Forney2019-11-20
| | | | These are really just regular arrays masquerading as VLAs.
* client: Include time.h for gmtime and strftimeMichael Forney2019-11-20
|
* Use strlcpy for sun_pathsJune McEnroe2019-11-20
| | | | | | | | | | | | My understanding is that sun_path need not be nul-terminated, but I didn't notice that SUN_LEN actually requires it. > The length of UNIX-domain address, required by bind(2) and connect(2), > can be calculated by the macro SUN_LEN() defined in <sys/un.h>. The > sun_path field must be terminated by a NUL character to be used with > SUN_LEN(), but the terminating NUL is not part of the address. Thanks to Duncan Overbruck <mail@duncano.de> for the report.
* 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.
* Mention the name CertFP in SASL EXTERNAL guide 1.0June McEnroe2019-11-18

* Document accept and exit behaviorJune McEnroe2019-11-18

* Remove ISUPPORT draft referenceJune McEnroe2019-11-18
| | | | | I don't actually deal with it at all other than storing them for syncing clients.
* Document inadvertent echo bugJune McEnroe2019-11-18
|
* Request NAMES on sync by defaultJune McEnroe2019-11-15
| | | | This inverts the meaning of -N!

|
* 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.
