2011-11-26net: Revert ARCNET and PHYLIB to tristate optionsBen Hutchings
commit 88491d8103498a6166f70d5999902fec70924314 ("drivers/net: Kconfig & Makefile cleanup") changed the type of these options to bool, but they select code that could (and still can) be built as modules.

2011-11-26ipv4: Don't use the cached pmtu informations for input routesSteffen Klassert
The pmtu informations on the inetpeer are visible for output and input routes. On packet forwarding, we might propagate a learned pmtu to the sender. As we update the pmtu informations of the inetpeer on demand, the original sender of the forwarded packets might never notice when the pmtu to that inetpeer increases. So use the mtu of the outgoing device on packet forwarding instead of the pmtu to the final destination. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S.

2011-11-26route: Use the device mtu as the default for blackhole routesSteffen Klassert
As it is, we return null as the default mtu of blackhole routes. This may lead to a propagation of a bogus pmtu if the default_mtu method of a blackhole route is invoked. So return dst->dev->mtu as the default mtu instead. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-11-23ehea: Reduce memory usage in buffer poolsAnton Blanchard
Now that we enable multiqueue by default the ehea driver is using quite a lot of memory for its buffer pools. With 4 queues we consume 64MB in the jumbo packet ring, 16MB in the medium packet ring and 16MB in the tiny packet ring. We should only fill the jumbo ring once the MTU is increased but for now halve it's size so it consumes 32MB. Also reduce the tiny packet ring, with 4 queues we had 16k entries which is overkill.

2011-11-23qlge: fix size of external list for TX address descriptorsThadeu Lima de Souza Cascardo
When transmiting a fragmented skb, qlge fills a descriptor with the fragment addresses, after DMA-mapping them. If there are more than eight fragments, it will use the eighth descriptor as a pointer to an external list. After mapping this external list, called OAL to a structure containing more descriptors, it fills it with the extra fragments. However, considering that systems with pages larger than 8KiB would have less than 8 fragments, which was true before commit a715dea3c8e, it defined a macro for the OAL size as 0 in those cases. Now, if a skb with more than 8 fragments (counting skb->data as one fragment), this would start overwriting the list of addresses already mapped and would make the driver fail to properly unmap the right addresses on architectures with pages larger than 8KiB. Besides that, the list of mappings was one size too small, since it must have a mapping for the maxinum number of skb fragments plus one for skb->data and another for the OAL. So, even on architectures with page sizes 4KiB and 8KiB, a skb with the maximum number of fragments would make the driver overwrite its counter for the number of mappings, which, again, would make it fail to unmap the mapped DMA addresses.

2011-11-23ipv6: tcp: fix tcp_v6_conn_request()Eric Dumazet
Since linux 2.6.26 (commit c6aefafb7ec6 : Add IPv6 support to TCP SYN cookies), we can drop a SYN packet reusing a TIME_WAIT socket. (As a matter of fact we fail to send the SYNACK answer) As the client resends its SYN packet after a one second timeout, we accept it, because first packet removed the TIME_WAIT socket before being dropped. This probably explains why nobody ever noticed or complained. Reported-by: Jesse Young <jlyo@jlyo.org> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

This patch adds in the infrastructure code to create the network priority cgroup.

This is a value that is both arbitrary and unique to a cgroup in this subsystem, and is used to index the per-device priority map 2) priomap - This is a writeable file. On read it reports a table of 2-tuples <name:priority> where name is the name of a network interface and priority is indicates the priority assigned to frames egresessing on the named interface and originating from a pid in this cgroup This cgroup allows for skb priority to be set prior to a root qdisc getting selected.
