proc/sys/net/sctp/* Variables:
addip_enable - BOOLEAN
Enable or disable extension of Dynamic Address Reconfiguration
(ADD-IP) functionality specified in RFC5061. This extension provides
the ability to dynamically add and remove new addresses for the SCTP
associations.
1: Enable extension.
0: Disable extension.
Default: 0
addip_noauth_enable - BOOLEAN
Dynamic Address Reconfiguration (ADD-IP) requires the use of
authentication to protect the operations of adding or removing new
addresses. This requirement is mandated so that unauthorized hosts
would not be able to hijack associations. However, older
implementations may not have implemented this requirement while
allowing the ADD-IP extension. For reasons of interoperability,
we provide this variable to control the enforcement of the
authentication requirement.
1: Allow ADD-IP extension to be used without authentication. This
should only be set in a closed environment for interoperability
with older implementations.
0: Enforce the authentication requirement
Default: 0
auth_enable - BOOLEAN
Enable or disable Authenticated Chunks extension. This extension
provides the ability to send and receive authenticated chunks and is
required for secure operation of Dynamic Address Reconfiguration
(ADD-IP) extension.
1: Enable this extension.
0: Disable this extension.
Default: 0
prsctp_enable - BOOLEAN
Enable or disable the Partial Reliability extension (RFC3758) which
is used to notify peers that a given DATA should no longer be expected.
1: Enable extension
0: Disable
Default: 1
max_burst - INTEGER
The limit of the number of new packets that can be initially sent. It
controls how bursty the generated traffic can be.
Default: 4
association_max_retrans - INTEGER
Set the maximum number for retransmissions that an association can
attempt deciding that the remote end is unreachable. If this value
is exceeded, the association is terminated.
Default: 10
max_init_retransmits - INTEGER
The maximum number of retransmissions of INIT and COOKIE-ECHO chunks
that an association will attempt before declaring the destination
unreachable and terminating.
Default: 8
path_max_retrans - INTEGER
The maximum number of retransmissions that will be attempted on a given
path. Once this threshold is exceeded, the path is considered
unreachable, and new traffic will use a different path when the
association is multihomed.
Default: 5
rto_initial - INTEGER
The initial round trip timeout value in milliseconds that will be used
in calculating round trip times. This is the initial time interval
for retransmissions.
Default: 3000

rto_max - INTEGER
The maximum value (in milliseconds) of the round trip timeout. This
is the largest time interval that can elapse between retransmissions.
Default: 60000
rto_min - INTEGER
The minimum value (in milliseconds) of the round trip timeout. This
is the smallest time interval the can elapse between retransmissions.
Default: 1000
hb_interval - INTEGER
The interval (in milliseconds) between HEARTBEAT chunks. These chunks
are sent at the specified interval on idle paths to probe the state of
a given path between 2 associations.
Default: 30000
sack_timeout - INTEGER
The amount of time (in milliseconds) that the implementation will wait
to send a SACK.
Default: 200
valid_cookie_life - INTEGER
The default lifetime of the SCTP cookie (in milliseconds). The cookie
is used during association establishment.
Default: 60000
cookie_preserve_enable - BOOLEAN
Enable or disable the ability to extend the lifetime of the SCTP cookie
that is used during the establishment phase of SCTP association
1: Enable cookie lifetime extension.
0: Disable
Default: 1
rcvbuf_policy - INTEGER
Determines if the receive buffer is attributed to the socket or to
association. SCTP supports the capability to create multiple
associations on a single socket. When using this capability, it is
possible that a single stalled association that's buffering a lot
of data may block other associations from delivering their data by
consuming all of the receive buffer space. To work around this,
the rcvbuf_policy could be set to attribute the receiver buffer space
to each association instead of the socket. This prevents the described
blocking.
1: rcvbuf space is per association
0: recbuf space is per socket
Default: 0
sndbuf_policy - INTEGER
Similar to rcvbuf_policy above, this applies to send buffer space.
1: Send buffer is tracked per association
0: Send buffer is tracked per socket.
Default: 0
sctp_mem - vector of 3 INTEGERs: min, pressure, max
Number of pages allowed for queueing by all SCTP sockets.
min: Below this number of pages SCTP is not bothered about its
memory appetite. When amount of memory allocated by SCTP exceeds
this number, SCTP starts to moderate memory usage.
pressure: This value was introduced to follow format of tcp_mem.
max: Number of pages allowed for queueing by all SCTP sockets.
Default is calculated at boot time from amount of available memory.
sctp_rmem - vector of 3 INTEGERs: min, default, max
See tcp_rmem for a description.
sctp_wmem - vector of 3 INTEGERs: min, default, max
See tcp_wmem for a description.
