[NET]: Optimize pskb_trim_rcsum()

2005-09-08T19:32:03+00:00

Since packets almost never contain extra garbage at the end, it is worthwhile to optimize for that case. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[NET]: skb_get/set_timestamp use const

2005-09-06T22:48:03+00:00

The new timestamp get/set routines should have const attribute on parameters (helps to indicate direction). Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[NET]: Implement SKB fast cloning.

2005-08-29T23:01:54+00:00

Protocols that make extensive use of SKB cloning, for example TCP, eat at least 2 allocations per packet sent as a result. To cut the kmalloc() count in half, we implement a pre-allocation scheme wherein we allocate 2 sk_buff objects in advance, then use a simple reference count to free up the memory at the correct time. Based upon an initial patch by Thomas Graf and suggestions from Herbert Xu. Signed-off-by: David S. Miller

[NET]: Fix sparse warnings

2005-08-29T23:01:32+00:00

Of this type, mostly: CHECK net/ipv6/netfilter.c net/ipv6/netfilter.c:96:12: warning: symbol 'ipv6_netfilter_init' was not declared. Should it be static? net/ipv6/netfilter.c:101:6: warning: symbol 'ipv6_netfilter_fini' was not declared. Should it be static? Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[NET]: Store skb->timestamp as offset to a base timestamp

2005-08-29T22:58:24+00:00

Reduces skb size by 8 bytes on 64-bit. Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

[NET]: Kill skb->real_dev

2005-08-29T22:32:25+00:00

Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument. It remains to be seen whether we can use this same exact thing to get rid of skb->input_dev as well. Signed-off-by: David S. Miller

[NET]: Reduce tc_index/tc_verd to u16

[NET]: Remove HIPPI private from skbuff.h

2005-08-29T22:31:42+00:00

This removes the private element from skbuff, that is only used by HIPPI. Instead it uses skb->cb[] to hold the additional data that is needed in the output path from hard_header to device driver. PS: The only qdisc that might potentially corrupt this cb[] is if netem was used over HIPPI. I will take care of that by fixing netem to use skb->stamp. I don't expect many users of netem over HIPPI Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[NET]: Kill skb->tc_classid

[NET]: Kill skb->list

2005-08-29T22:31:14+00:00

Remove the "list" member of struct sk_buff, as it is entirely redundant. All SKB list removal callers know which list the SKB is on, so storing this in sk_buff does nothing other than taking up some space. Two tricky bits were SCTP, which I took care of, and two ATM drivers which Francois Romieu fixed up. Signed-off-by: David S. Miller Signed-off-by: Francois Romieu
