Large buffer in kernel space

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

Can somebody please explain to me, which method should I use to build (for
kernel space manipulation only) large (20MB-30MB) buffer in memory that can
be used across /net/ipv4/*.c files? It is mainly for mining some data in IP
packet processing process... (but needs to be large because i want to run
2Mbps flows)

Shoould I use kmalloc vmalloc or sth else? How should I pass an address to
this (allocated) memory to other files that will use it to insert some data
into??

thanks for any suggestions
