- Add outbound name
- Add outbound conn in ctx
- Refactor splice: it can be turn on from all inbounds and outbounds
- Refactor splice: Add splice copy to vless inbound
- Fix http error test
- Add freedom splice toggle via env var
- Populate outbound obj in context
- Use CanSpliceCopy to mark a connection
- Turn off splice by default
In the past, we use Starlark script, it is over engineered and barely used.
By switching to simple key value string contains logic we can reduce core size about 0.7MB
* Vision server allow multiple blocks of padding
* Fix Vision client to support multiple possible padding blocks
* Vision padding upgrade
- Now we have two types of padding: long (pad to 900-1400) and traditional (0-256)
- Long padding is applied to tls handshakes and first (empty) packet
- Traditional padding is applied to all beginning (7) packets of the connection (counted two-way)
- Since receiver changed its way to unpad buffer in fd6973b3c6, we can freely extend padding packet length easily in the future
- Simplify code
* Adjust receiver withinPaddingBuffers
Now default withinPaddingBuffers = true to give it a chance to do unpadding
* Fix magic numbers for Vision
Thanks @H1JK
Thanks @RPRX for guidance
This only affects the Vision client for protocols expecting server to send data first.
The change is compatible with existing version of Vision server.
* Add fingerprint xray_random
xray_random means to pick a random uTLS fingerprint at the core startup
This way, the fingerprint is stable for a user for some days. While there is no identifiable signature for the whole xray community
* Fingerprint "random" refine
Exclude old fingerprint from RNG
In the past, when user open xtls vision on the server side, plain vless+tls can connect.
Pure tls is known to have certain tls in tls characters.
Now server need to specify "xtls-rprx-vision,none" for it be able usable on the same port.
Before this change, Vision client need a pure inbound like socks or http.
After this change, it will support any inbound.
This is useful in traffic forwarder use case inside China.
* Add XTLS RPRX's Vision
* Add helpful warning when security is wrong
* Add XTLS padding (draft)
* Fix number of packet to filter
* Xtls padding version 1.0 and unpadding logic
* Fix UDP destination override
* Fix code style
* Fix fakedns object init
Do type convertion at runtime in case if user don't use fakedns in config.
Since dispatcher now depend on fakedns object, move the injection order of
fakedns to top (As a temporary solution)
* Amend logic for handing fakedns client
A map is used by server side when client turn on fakedns
Client will send domain address in the buffer.UDP.Address, server record all possible target IP addrs.
When target replies, server will restore the domain and send back to client.

* Fix some tests to PickPort correctly
* Add retry logic for two socks tests
Two socks tests listen for both TCP and UDP with same port number, in some cases the port is not available
Add retry logic for server core, start server core and client core separately
Extract a common method
* Add retry logic for two dokodemo tests
Two dokodemo tests listen for 5 ports, in some cases they are not available
Add retry logic for client core, start server and client separately
* Fix Dial function crash instance when there is no instance context in the ctx
* check ctx to fix. (#841)
* Feat: core.ToContext(ctx, v) for ctx initialization (#852)
* remove exported API: toContext
* Remove unnecessary API
* rework document for API
* fix: make sure the ctx is propagated to connections by detached connection

* DialSystem for Quic
DialSystem() is needed in case of Android client,
where the raw conn is protected for vpn service
* Fix client dialer log
Log such as:
tunneling request to tcp:www.google.com:80 via tcp:x.x.x.x:443
the second "tcp" is misleading when using mKcp or quic transport
Remove the second "tcp" and add the correct logging for transport dialer:
- transport/internet/tcp: dialing TCP to tcp:x.x.x.x:443
- transport/internet/quic: dialing quic to udp:x.x.x.x:443
* Quic new stream allocation mode
Currently this is how Quic works: client muxing all tcp and udp traffic through a single session, when there are more than 32 running streams in the session,
the next stream request will fail and open with a new session (port). Imagine lineup the session from left to right:
|
| |
| | |
As the streams finishes, we still open stream from the left, original session. So the base session will always be there and new sessions on the right come and go.
However, either due to QOS or bugs in Quic implementation, the traffic "wear out" the base session. It will become slower and in the end not receiving any data from server side.
I couldn't figure out a solution for this problem at the moment, as a workaround:
| |
| | |
| | |
I came up with this new stream allocation mode, that it will never open new streams in the old sessions, but only from current or new session from right.
The keeplive config is turned off from server and client side. This way old sessions will natually close and new sessions keep generating.
Note the frequency of new session is still controlled by the server side. Server can assign a large max stream limit. In this case the new allocation mode will be similar to the current mode.
Occasional error is observed when we execute long test
Print time and memory for better troubleshooting in the future

Core setup router object first, when InjectContext() is called, observatory object is still null,
so observatory need to be injected after InjectContext()
* verify peer cert function for better man in the middle prevention
* publish cert chain hash generation algorithm

* apply coding style
* added test case for pinned certificates
* refactored cert pin
* pinned cert test
* added json loading of the PinnedPeerCertificateChainSha256
* removed tool to prepare for v5
* Add server cert pinning for Xtls
Change command "xray tls certChainHash" to xray style
