and CONFIG_NET_DMA is enabled.
Default: 4096
+UDP variables:
+
+udp_mem - vector of 3 INTEGERs: min, pressure, max
+ Number of pages allowed for queueing by all UDP sockets.
+
+ min: Below this number of pages UDP is not bothered about its
+ memory appetite. When amount of memory allocated by UDP exceeds
+ this number, UDP 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 UDP sockets.
+
+ Default is calculated at boot time from amount of available memory.
+
+udp_rmem_min - INTEGER
+ Minimal size of receive buffer used by UDP sockets in moderation.
+ Each UDP socket is able to use the size for receiving data, even if
+ total pages of UDP sockets exceed udp_mem pressure. The unit is byte.
+ Default: 4096
+
+udp_wmem_min - INTEGER
+ Minimal size of send buffer used by UDP sockets in moderation.
+ Each UDP socket is able to use the size for sending data, even if
+ total pages of UDP sockets exceed udp_mem pressure. The unit is byte.
+ Default: 4096
+
CIPSOv4 Variables:
cipso_cache_enable - BOOLEAN
icmp_ratelimit - INTEGER
Limit the maximal rates for sending ICMP packets whose type matches
icmp_ratemask (see below) to specific targets.
- 0 to disable any limiting, otherwise the maximal rate in jiffies(1)
- Default: 100
+ 0 to disable any limiting,
+ otherwise the minimal space between responses in milliseconds.
+ Default: 1000
icmp_ratemask - INTEGER
Mask made of ICMP types for which rates are being limited.
icmp/*:
ratelimit - INTEGER
Limit the maximal rates for sending ICMPv6 packets.
- 0 to disable any limiting, otherwise the maximal rate in jiffies(1)
- Default: 100
+ 0 to disable any limiting,
+ otherwise the minimal space between responses in milliseconds.
+ Default: 1000
