Subject: [PATCH 0/3] UDP memory accounting and limitation (take 12)

Hello,

This is the latest patch set of UDP memory accounting and limitation.

I split my patch set into accounting interface consolidation and UDP
memory accounting support. This patch set implements UDP memory
accounting support.

To use consolidated accounting functions, I matched format of udp_mem
sysctl with tcp_mem. UDP IPv6 is finally supported.

However, currently, only receive buffer accounting is implemented.

The patch set was tested on net-2.6.25 tree.


Changelog take 11 -> take 12:
 * split into accounting interface consolidation and UDP memory
   accounting support.
 * used new accounting interface
 * supported IPv6
 * dropped send buffer accounting

Changelog take 10 -> take 11:
 * stoped using spin lock in memory accounting function
 * socket lock and backlog processing were used to avoid conflict
   between receive system call processing and BH
 * revised memory accounting functions
 * stooped changing sock_queue_rcv_skb() and skb_set_owner_r()
 * added __udp_queue_rcv_skb to set proper destructor
 * removed udp_set_owner_r()
 * removed reclaim in inet_sock_destruct()

Changelog take 9 -> take 10:
 * supported using sk_forward_alloc
 * introduced several memory accounting functions with spin lock
 * changed detagram receive functions to be able to customize
   destructor
 * fixed accounting bugs in previous takes

Best regards,
Hideo Aoki
