net: Add sysctl to toggle early demux for tcp and udp

2017-03-24T20:17:07+00:00

Certain system process significant unconnected UDP workload. It would be preferrable to disable UDP early demux for those systems and enable it for TCP only. By disabling UDP demux, we see these slight gains on an ARM64 system- 782 -> 788Mbps unconnected single stream UDPv4 633 -> 654Mbps unconnected UDPv4 different sources The performance impact can change based on CPU architecure and cache sizes. There will not much difference seen if entire UDP hash table is in cache. Both sysctls are enabled by default to preserve existing behavior. v1->v2: Change function pointer instead of adding conditional as suggested by Stephen. v2->v3: Read once in callers to avoid issues due to compiler optimizations. Also update commit message with the tests. v3->v4: Store and use read once result instead of querying pointer again incorrectly. v4->v5: Refactor to avoid errors due to compilation with IPV6={m,n} Signed-off-by: Subash Abhinov Kasiviswanathan Suggested-by: Eric Dumazet Cc: Stephen Hemminger Cc: Tom Herbert Cc: David Miller Signed-off-by: David S.

ipv6: Pull IPv6 GSO registration out of the module

2012-11-15T22:39:24+00:00

Sing GSO support is now separate, pull it out of the module and make it its own init call. Remove the cleanup functions as they are no longer called. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

ipv6: Add new offload registration infrastructure.

2012-11-15T22:36:17+00:00

Create a new data structure for IPv6 protocols that holds GRO/GSO callbacks and a new array to track the protocols that register GRO/GSO. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

inet: Sanitize inet{,6} protocol demux.

2012-06-20T01:56:21+00:00

Don't pretend that inet_protos[] and inet6_protos[] are hashes, thay are just a straight arrays. Remove all unnecessary hash masking. Document MAX_INET_PROTOS. Use RAW_HTABLE_SIZE when appropriate. Reported-by: Ben Hutchings Signed-off-by: David S. Miller

net: add __rcu annotations to protocol

2010-10-27T18:37:31+00:00

Add __rcu annotations to : struct net_protocol *inet_protos struct net_protocol *inet6_protos And use appropriate casts to reduce sparse warnings if CONFIG_SPARSE_RCU_POINTER=y Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
