/proc/sys/net/mptcp/* 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.
|
|
|
|
Default: 120
|
|
|
|
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.
|
|
|
|
Default: 0
|
|
|
|
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.
|
|
|
|
Default: 1
