ValdikSS	27a6d256f0	Handle HTTP GET and POST in packets larger than --max-payload If --max-payload 1200 is used and there's HTTP request with lots of cookies which exceed 1200 bytes in size, this packet would have been skipped as 'too large', and the circumvention won't be applied. Fix this by checking for "GET " or "POST" in the beginning of the packet regardless of its size.	3 years ago

ValdikSS	d7c681d1a2	Add Max Payload Size limit option (`--max-payload-size`) This option excludes TCP packets with the data payload larger than defined value from being copied by WinDivert driver to GoodbyeDPI. As most of HTTP and TLS ClientHello packets are repatively small, and file transfers are usually big and are sent/received using the whole available MTU/MSS, we can just exclude them from being processed by our userspace program to reduce unnecessary CPU load.	3 years ago
ValdikSS	ab74ddc425	Update readme	3 years ago
ValdikSS	cc1676ad92	--allow-no-sni option. Useful with --blacklist and undetectable SNI. This option is added specially for protonmail.com, as it sends low Window Size in SYN-ACK for requests from Russia, to force the client to fragment the packet. GoodbyeDPI doesn't do reassembling and can't extract SNI in this case, thus won't circumvent the censorship if --blacklist option is used.	3 years ago

ValdikSS	46c4f36de8	Add Fake Packet maximum TTL limit to Auto TTL mode This patchset adds maximum TTL size of the fake packet to be sent, to further improve compatibility with asymmertic routing and non-standard TTL value set on servers.	3 years ago

ValdikSS	bb8bafb663	Add Auto TTL range adjustment, introduce min-ttl and use it for --set-ttl as well.	3 years ago
ValdikSS	e25d7432de	Better Auto TTL adjusting algorithm which honors short distance Say you set --auto-ttl to 4. If the TTL distance to the destination host is too short, say 6, auto-ttl would decrease it by 4 and send a fake packet with TTL 2, which is too low for the packet to travel via DPI system. But if you set --auto-ttl to a lower value such as 2, that may introduce issues over long lines where outgoing-path TTL and incoming-path TTL may have difference more than 2 hops due to higher chance of assymetric routing along the path. To solve this issue, this commit introduce auto-ttl range of two values. If the incoming TTL distance is more than autottl2, it is subtracted by autottl2 value. If the distance is less than autottl2, the distance value is used as a normalized weigth of [autottl1; autottl2] scale. The simplified formula is as follows: 128 > extracted_ttl > 98: // Server is running Windows nhops = 128 - extracted_ttl 64 > extracted_ttl > 34: // Server is running Linux/FreeBSD/other nhops = 64 - extracted_ttl if (nhops - autottl2 < autottl2) ttl_of_fake_packet = nhops - autottl1 - trunc((autottl2 - autottl1) * ((float)nhops/10)); else ttl_of_fake_packet = nhops - autottl2	3 years ago
