for sending replies to received ECHO (ping) requests.

---help---
|

Enable support for IPPROTO_ICMP sockets. These sockets are needed
|
|
for application level support for sending ECHO (ping) requests and
|
|
receiving associated ECHO replies.

int "Preallocated ICMP packet sockets"

default 4
|
|
---help---
|
|
Number of ICMP connections (all tasks).
|
|
|
|
This number of connections will be pre-allocated during system boot.
|
|
If dynamic connections allocation is enabled, more connections may
|
|
be allocated at a later time, as the system needs them. Else this
|
|
will be the maximum number of connections available to the system
|
|
at all times.
|
|
|
|
Set to 0 to disable (and rely only on dynamic allocations).
|
|
|
|
config NET_ICMP_ALLOC_CONNS
|
|
int "Dynamic ICMP connections allocation"
|
|
default 0
|
|
---help---
|
|
Dynamic memory allocations for ICMP.
|
|
|
|
When set to 0 all dynamic allocations are disabled.
|
|
|
|
When set to 1 a new connection will be allocated every time,
|
|
and it will be free'd when no longer needed.
|
|
|
|
Setting this to 2 or more will allocate the connections in
|
|
batches (with batch size equal to this config). When a
|
|
connection is no longer needed, it will be returned to the
|
|
free connections pool, and it will never be deallocated!

|
int "Maximum number of ICMP connections"

depends on NET_ICMP_ALLOC_CONNS > 0
|
|
---help---
|
|
If dynamic connections allocation is selected (NET_ICMP_ALLOC_CONNS > 0)
|
|
this will limit the number of connections that can be allocated.
|
|
|
|
This is useful in case the system is under very heavy load (or
|
|
under attack), ensuring that the heap will not be exhausted.
