SPDX-License-Identifier: GPL-2.0 ===================== MPTCP Sysfs variables ===================== /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 stale_loss_cnt - INTEGER The number of MPTCP-level retransmission intervals with no traffic and pending outstanding data on a given subflow required to declare it stale. The packet scheduler ignores stale subflows. A low stale_loss_cnt value allows for fast active-backup switch-over, an high value maximize links utilization on edge scenarios e.g. lossy link with high BER or peer pausing the data processing. This is a per-namespace sysctl. Default: 4 |
