2019-11-21Fix wordcmp return value when the words have differing lengthsMichael Forney
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.
2019-11-21Declare globals as extern in headers, and define in source fileMichael Forney
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.

2019-11-21Use a static buffer for plainBase64June McEnroe
2019-11-21Use a fixed buffer size for SASL PLAIN authenticationMichael Forney
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.
2019-11-20Avoid a couple VLAs with constant sizeMichael Forney
These are really just regular arrays masquerading as VLAs.

2019-11-20Use strlcpy for sun_pathsJune McEnroe
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.
2019-11-20Format milliseconds as intJune McEnroe
I don't know what I was thinking. I'm expecting a number less than 1000 of course that fits in int.

I don't actually deal with it at all other than storing them for syncing clients.

This inverts the meaning of -N!

2019-11-14Remove server-time filter TODOJune McEnroe
I think it's fine to keep it separate since it's a core function of the bouncer.

2019-11-11Revert "Test getopt_config"June McEnroe
This reverts commit c8a771828e1d5fc8c476bbd650fafcfb7ba390a8. It just feels gross... idk.

2019-11-11Skip initial NAMES parametersJune McEnroe
Channel names can contain '!' so splitting the whole message on it won't work. I hate this code though.
2019-11-11Filter userhost-in-namesJune McEnroe
I really want to be writing tests for these functions...

2019-11-09Remove extended-join and invite-notifyJune McEnroe
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.
2019-11-09Maintain stateCaps and offer them to clientsJune McEnroe
2019-11-09Parse capabilitiesJune McEnroe
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.

2019-11-08Avoid calling getopt_long again after it returns -1June McEnroe
On GNU, calling getopt_long again will reset optind back to the first non-option argument, which would cause an infinite loop of reading the same configurtion file forever.
2019-11-08Only change AWAY status for registered clientsJune McEnroe
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.

2019-11-07Include path in readlinkat errorJune McEnroe
2019-11-07Call clientConsume before clientRecvJune McEnroe
This might reduce the frequency of a client getting its own message back because it was behind in the ring when it sent it.
