sorry but this is probaly a dumb quston as i baraly know c++ but why is Kernel() defined here but not here?

kernel.h is not included anywhere in the include path for that file, but it should work if you add it I think

i already tried that

Image attachment

#include "kernel.h"

in the image its there

02:15

oh put it in ""s ok

02:15

whats the difrence?

doing <kernal.h> will only work if it's in the same folder as you file you wrote that in

ah ok

#include <engine/kernel.h> should also work

good as putting it in ""s didnt

yeah it doesn't make any difference in this case

still not working it seems

Image attachment

idk just use the first one then

02:19

I don't have an editor open to figure out what the path should be

that also doesnt work though

hmm

wait do i need to put it in the .h file too?

02:20

wait where is the .h file???

network.h

02:21

idk why it doesn't work

ah ok

02:25

ok looks like ill just have to use io_open() drectly

02:30

burh you literaly have system.sh already included!

is vscode just being stupid?

02:32

i mean ig theres only one way to find out. its compileing time!

02:35

wait a second its because there is no storage.h file

02:35

but then how in the world would i refrence it

02:37

ok no its not just vscode being dumb it realy doesnt work

i am so confused

tldr what happened

im trying to call a funcson from a dif file but i cant get it to work

is there any setting which gives pistol bullets gravity?

and idk why

06:55

also wow did both of you suddenly appear at once?

MilkeeyCat

is there any setting which gives pistol bullets gravity?

yes

which one? xd

gun curvature or smth

06:56

Check ddnet settings commands page

there's gun_curvature, thanks, curvature is not the word I was looking for xd

so does anyone know what stupid mastake im making? https://discord.com/channels/252358080522747904/293493549758939136/1341229474657599520

hmm is there a pointer to the client in network.h? You might be able to get a reference to the over some other pointer within CNetClient. I'm home in 7 hours if you still need help then. GitHub code browsing is shit on mobile (edited)

07:03

@Tater can u check for me what CNetClient::m_pUser is set to? xd

07:03

ah fk

Is CNetClient subclass of Interface?

[ddnet/ddnet] Issue opened: #9703 Incorrect bullet rendering in demo

!Image Was broken in #9174

Pioooooo

Is CNetClient subclass of Interface?

if the .h file for network is where that would be then no

Oops I mean IInterface

doesnt look like it

Image attachment

08:19

why?

Because it isn't

08:20

gigachad

wait so how does the fact that it doesnt inherit from IInterface help me open a file?

Idk u asked why Kernel is not defined and this is why

08:22

Because it is a member function of IInterface

ah hmm so how would i refrence it then (agien c++ noob here)

Idk maybe u shouldn't use it here if u just want to open some random file for fuzzing

true

08:25

ill just look up how to open a file in c++ the normal way lol

08:31

also before i go to sleep in advance does anyone know what funcson gets called when the client disconects from the server? as i want to exit the program if that happens for fuzzing

08:36

bruh not even the normal way of opening files works??? im including the needed namespaces i thought

Image attachment

Image attachment

08:38

@Pioooooo do you know what im doing wong this time?

std::ifstream

@Pioooooo do you know what im doing wong this time?

ah lol

08:40

thanks

08:40

frogot thats how you acsess the meathod of a class in c++

08:40

or was it namespace

08:40

idr

It's a namespace

ok now to figger out why this isnt working and what the real way to do it is thats not in all of the exsamples i can find online

Here's a video recorded on a server running 15.3.2. The same effect can also be seen on older demos that were recorded on these older server versions. Expected behavior: the cursor shouldn't be shown because there is missing data. https://github.com/user-attachments/assets/f9ef9275-72cd-4008-9b34-07c50ad3ecc5 demo.zip

Hallo, Marcel D'Avis

Wir gehen erst, wenn Ihr Anschluss läuft.

dos shnitzal

I recently saw a map with a kog 2.0 soon

19:39

thats why

yeah, haters gonna hate

what is Kog2.0?

Discord mobile is so weird, in some places they render discord emoji and the system emoji in others

Nameless_Me

what is Kog2.0?

updated kog

fokkonaut

updated kog

so, just, kog? How is it diffrent?

i think it's the new source + login system etc

new game basically

+ fucking /save and /swap disabled angry

angry

built with unreal engine

AND /PRACTICE

ye but did you add sex?

that escalated quickly

i'll take that as a yes

Avolicious

that escalated quickly

Why did you disable the 3 commands?

just because to make you ask

I understand swap and save, for names

19:44

logins*

to get you distracted from 1&1 re-selling

Good

19:45

I believe you

eserde: Don't stop at the first deserialization error - Mainmatter

eserde can be used to collect multiple deserialization errors, rather than stopping at the first one. They can then be reported to the user at once, improving the developer experience for API consumers.

for fuzzing the networking is it fine to just ignore the clients packets or do any of them contain info that i need to send pack to the client

22:24

and is there any more checksums then the maps checksums

Some of those sent during the connecting process are necessary or the process won't advance. I'd maybe do separate runs for the connecting process and ingame, where you start the fuzzing a bit later.

hey awesome

22:29

this is exactly what i need

22:30

some SaaS we use provides us with an OpenAPI doc that it does not adhere to and the types we use are generated from that doc (edited)

22:30

we had a random error where one field they marked as non-optional but provided us with null and serde sent the whole thing crashing xd

Robyt3

Some of those sent during the connecting process are necessary or the process won't advance. I'd maybe do separate runs for the connecting process and ingame, where you start the fuzzing a bit later.

is that for the checksums or ignoreing the clients packets (edited)

Both. If the checksums in the map info don't match the map then the client will disconnect. If the client doesn't get some messages it will stop during the connecting process.

ok but the messages the client needs to receve dont depend on what the client sends the server right?

22:33

the fuzzing can figger out what messages to send to connect

I guess if the fuzzer is smart enough then that's alright. It goes back and forth during connecting, the client sends ready after loading the map, then the server sends back ready so the client joins

oh ok so if the server sends ready before the client it wouldnt work? (edited)

22:39

so in outer words i cant just send all the packets in 1 frame

The client should ignore messages when it doesn't expect them so connection wouldn't work, but there are also still crashes (and various open issues) because it doesn't ignore all.

david loves Jellycar Worlds

so in outer words i cant just send all the packets in 1 frame

yeah, the client couldn't respond fast enough

how long should i delay each packet do you think

I don't know if delaying works. I only tried a bit of network fuzzing where I mutated the existing message data but didn't generate new messages directly. (edited)

ok well ill at least try

22:42

btw where is the servers code so i can make it send 1 packet each frame?

probably not, writing a fuzzing test driver is probably the first challenge

22:44

unless you use the easier method of only mutating existing data, but I don't know if that works with AFL++, and it wasn't very effective with radamsa (edited)

yea hence why im trying this meatod

22:44

instead

22:47

so do you know where the servers code is?

You mean networking?

yea

src/engine/shared/network*

22:48

and basic functions for interacting with sockets in system.cpp/h

ok thanks

depends on the abstraction layer where you want to start fuzzing

im currently pretending like you got completly difrent packets on the client side then the server sends

22:49

by editing CNetClient::Recv

22:49

wait is that used by the server too?

22:49

probs not

given the name has Client in it
