MPTCP Sysfs variables¶
- enabled - BOOLEAN
Control whether MPTCP sockets can be created.
MPTCP sockets can be created if the value is 1. This is a per-namespace sysctl.
Default: 1 (enabled)
- add_addr_timeout - INTEGER (seconds)
Set the timeout after which an ADD_ADDR control message will be resent to an MPTCP peer that has not acknowledged a previous ADD_ADDR message.
The default value matches TCP_RTO_MAX. This is a per-namespace sysctl.
- checksum_enabled - BOOLEAN
Control whether DSS checksum can be enabled.
DSS checksum can be enabled if the value is nonzero. This is a per-namespace sysctl.
- allow_join_initial_addr_port - BOOLEAN
Allow peers to send join requests to the IP address and port number used by the initial subflow if the value is 1. This controls a flag that is sent to the peer at connection time, and whether such join requests are accepted or denied.
Joins to addresses advertised with ADD_ADDR are not affected by this value.
This is a per-namespace sysctl.
