net: Kill skb_truesize_check(), it only catches false-positives.

2009-03-17T00:31:55+00:00

[ Upstream commit 92a0acce186cde8ead56c6915d9479773673ea1a ] A long time ago we had bugs, primarily in TCP, where we would modify skb->truesize (for TSO queue collapsing) in ways which would corrupt the socket memory accounting. skb_truesize_check() was added in order to try and catch this error more systematically. However this debugging check has morphed into a Frankenstein of sorts and these days it does nothing other than catch false-positives. Signed-off-by: David S.

net: packet split receive api

2008-10-07T21:22:33+00:00

Add some packet-split receive hooks. For one this allows to do NUMA node affine page allocs. Later on these hooks will be extended to do emergency reserve allocations for fragments. Signed-off-by: Peter Zijlstra Signed-off-by: David S. Miller

net: add skb_recycle_check() to enable netdriver skb recycling

2008-10-01T09:33:12+00:00

This patch adds skb_recycle_check(), which can be used by a network driver after transmitting an skb to check whether this skb can be recycled as a receive buffer. skb_recycle_check() checks that the skb is not shared or cloned, and that it is linear and its head portion large enough (as determined by the driver) to be recycled as a receive buffer. If these conditions are met, it does any necessary reference count dropping and cleans up the skbuff as if it just came from __alloc_skb(). Signed-off-by: Lennert Buytenhek Signed-off-by: David S.

net: Add skb_queue_walk_from() and skb_queue_walk_from_safe().

2008-09-23T07:49:44+00:00

These will be used by TCP write queue handling and elsewhere. Signed-off-by: David S. Miller

net: Add skb_queue_next().

2008-09-23T07:44:42+00:00

A lot of code wants to iterate over an SKB queue at the top level using it's own control structure and iterator scheme. Provide skb_queue_next(), which is only valid to invoke if skb_queue_is_last() returns false. Signed-off-by: David S. Miller

net: Add skb_queue_is_last().

2008-09-23T07:34:07+00:00

Several bits of code want to know "is this the last SKB in a queue", and all of them implement this by hand. Provide an common interface to make this check. Signed-off-by: David S. Miller

net: Fix bus in SKB queue splicing interfaces.

2008-09-23T04:57:21+00:00

Handle the case of head being non-empty, by adding list->qlen to head->qlen instead of using direct assignment. Signed-off-by: David S. Miller

net: Add new interfaces for SKB list light-weight init and splicing.

2008-09-22T05:36:24+00:00

This will be used by subsequent changesets. Signed-off-by: David S. Miller

net: Add SKB DMA mapping helper functions.

net: Add DMA mapping tokens to skb_shared_info.
