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 -- Hitachi Computer Products (America) Inc. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
