The ModList packet right before crashing is actually sent from the client: Sending plugin message: channel=FML|HS, data=[2, 183 if I abort before sending this message, no server error log. Likewise if I abort right after, then the server does log the "java.util.zip.DataFormatException: incorrect header check" error when inflating. So the client is confusing the server. SevTech: 5140 bytes, Beyond: 3823 bytes, Skyfactory: 3809 bytes. Is this beyond some threshold where the packet is supposed to be compressed? No mention of compression on https://wiki.vg/Minecraft_Forge_Handshake but it is only updated for 1.7-1.9, maybe there was a Forge or vanilla change in 1.10+? https://github.com/MinecraftForge/MinecraftForge/commits/1.10.x has some changes related to multipart packets (FML|MP), but those are only server to client, not client to server. https://wiki.vg/Protocol#Packet_format - with and without compression Receiving from server: packet = Some(SetInitialCompression(SetInitialCompression { threshold: 256 })) This is handled and set in Conn compression.threshold, used in write_packet(), so it should be compressed.

}The encoder is initialized once, lazily, with an io::Cursor to an empty buffer. The encoder is then reset to a cursor of the buffer to compress. This causes different results, a corrupt deflate stream, versus initializing the encoder with the input buffer itself. Does compression need a running stream like encryption, or can the encoder be reconstructed on each use? Why does initializing with an empty buffer and resetting produce different results than initializing with the data? It is possible this was always broken, testing on a few server configurations, this code path was not hit. |
|
Changing to initialize with the input, each time, able to connect to FTB Beyond:
but are there other consequences? How many times is encryption used, need to confirm additional state is not needed for multiple packets. If not, could remove the compression_write (and compression_read?) member variables entirely. Is compression_read broken too? Uses same io::Cursor technique. Is it possible to stick with cursors but fix the decompression/compression? |
|
Compressing the compressed = [120, 1, 99, 100, 98, 6, 0, 0, 13, 0, 7] Compressing the cursor... produces correct results if initializing with the data, but not if initializing with empty then resetting - seems to be missing header/trailer? compressed = [99, 100, 98, 6, 0] New reduced test case: use std::io::{self, Read};
use flate2::{Compression, read::{ZlibDecoder, ZlibEncoder}};
const USE_RESET: bool = true;

Reading to the end of the encoder after creating it, but before resetting, shows it has data: read empty = [120, 1, 3, 0, 0, 0, 0, 1] This is the missing header we seek. But it wouldn't be available if the encoder is lazily initialized. What was the point of the compression_write member variable anyways, it was present very early in the project, among the first commits: 6f6d3c96 Main part of the protocol complete, with a curious comment: compression_read: Option<ZlibDecoder<io::Cursor<Vec<u8>>>>, // Pending reset support
compression_write: Option<ZlibEncoder<io::Cursor<Vec<u8>>>>,The "// Pending reset support" comment was removed in 8a2c247 Minor changes, maybe reset never worked as expected here, since the headers are missing... although, I did update flate2 myself in #4 fd2c51ea |

Previously, the zlib compressor was initialized once, lazily, then reused for each packet by resetting the stream. This didn't properly emit the zlib headers, so packet compression was broken and caused "java.util.zip.DataFormatException: incorrect header check" on the server. Since packets are only compressed above a threshold, this problem manifested itself only on larger servers, such as 1.10.2 FTB Beyond and Skyfactory 3, and 1.12.2 SevTech: Ages, which require sending a large ModList above the compression threshold enabled by the server. Change to instead recreate the zlib compressor, each time it is used as to capture the full header. For symmetry, the decompressor is also recreated each time. * Removes self.compression_write and self.compression_read instance variables * Remove self.compression_write, initialize with cursor * Log compressing/decompressing packets in network debug mode
