__inte_lookup_established: kernel 2.6.15

[Vikas Aggarwal <vik.reck@xxxxxxxxx>]

Hi,

 Can someone provide me a doucmentation or his knowledge about the function

  static inline struct sock * __inet_lookup_established(struct inet_hashinfo *hashinfo,
                                   const u32 saddr, const u16 sport,  const u32 daddr, const u16 hnum,
                                  const int dif)

File:

lxr/source/include/net/inet_hashtables.h#378

kernel:2.6.15

 

By the name it appears it is  going  through hash table for ESTABLISHED state socket.

 

Can someone please send some code commentry or some details about the tables it is going through.

 

Is there a known documentation to describe this implementation.

 

thanks much in advance

vik.
