CentralNode 7.1

7111 notice

This is a TESTING build, this program is NOT complete.

Info

So I've decided to make this spaghetti public, in case there are good souls willing to test it and hunt for bugs.
They are all over the place, creeping from the bushes, waiting to throw SEGFAULTS at people.
If you find a bug, please create a new issue,
or shoot me a message on Discord xoreaxeax#9705
Thank you very much.

Supported terminals:

Feel free to create a pull request if you find additional terminals that work with CNODE

gnome-terminal
terminator
WSL terminal
rxvt
rxvt-unicode

Unsupported terminals:

These terminals don't support changing color palettes, if you find any new, fire up a pull request. Thank you

qterminal - qterminal is demented, along with it's color palette that cannot be changed (at least I couldn't find it in preferences)
xterm - raw xterm doesn't seem to support ncurses colors
konsole - :( that's just sad and depressing

Dependencies:

uuid-dev
libcurl4
ncurses
libssl

Building tools:

make
nasm
gcc

Building:

make

Code notes:

Coding style:

As of right now, just stick to these few basic rules, everything will be polished either way when complete

1. Keep the opening curly bracket on the same line as function definitions.
2. case is indented by one level from switch:

switch (number) {
    case 1:
        break;
    default:
        break;
}

3. NODE_SETLASTERR() needs to be the first thing called on error, inside the function where the error happened.

Spaghetti

I know this code is a lot of spaghetti bolognese, but at this point, I just wanna push it out to (semi) functional state while slowly working on untangling it all, piece by piece.
If you feel like improving some code, shoot a pull request

Include files

I know this may sound non-standard, but internal headers are included before system headers, so please follow that, or stuff will go break break (wow, wonderful)

NODE_SETLASTERR() rule:

As mention above, this is always called inside the function where error happens, never outside of it.
NODE_SETLASTERR() calls log_write(LOG_ERROR, ...) and automataically logs errors, if possible.
log_write_trace() only logs messages with DEBUG logging level.

Memory leaks

As of build 7111, all memory allocations are free'd. Valgrind will show some lost bytes, but all of them should be tied to ncurses window functions. This is NOT a leak. Address Sanitizer is set-up in Makefile, please test Central Node with ASAN present.

log_write() warning

log_write() does NOT check for erroneous format specifiers, neither does the compiler. This is why logging should be done by NODE_SETLASTERR(), but if it's necessary, always double check the stuff and arguments you feed log_write() with.

TODO:

• tinc daemon ctl
• tinc config exchange system
• Config editing from TUI
• Panic mode
• nodeWD

Additional notes

There is an issue present with generation 2 of Windows Subsystem Linux, where the system reports an incorrect number of network interfaces, which are passsed to ioctl() by Central Node. This results in the following error message being written to the log file over and over again:
[Mon Jan 01 12:00:00 00]-[ERR]: I/O control operation failed: Cannot assign requested address
This issue is not present on generation 1 WSL. I'll figure out a solution to this soon.
