Spring cleaning time... There seems to be a lot of places in the network code that have extra bogus semicolons after conditionals. Most commonly is a bogus semicolon after: switch() { } Signed-off-by: NStephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This is an implementation of TCP Illinois invented by Shao Liu at University of Illinois. It is a another variant of Reno which adapts the alpha and beta parameters based on RTT. The basic idea is to increase window less rapidly as delay approaches the maximum. See the papers and talks to get a more complete description.

Add a packet socket option to allow the orig_dev index to be returned to userspace when passing traffic through a decapsulated device, such as the bonding driver. This is very useful for layer 2 traffic being able to report which physical device actually received the traffic, instead of having the encapsulating device hide that information. The new option is called PACKET_ORIGDEV. Signed-off-by: NPeter P. Waskiewicz Jr. <peter.p.waskiewicz.jr@intel.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add IP(V6)_PMTUDISC_PROBE value for IP(V6)_MTU_DISCOVER. This option forces us not to fragment, but does not make use of the kernel path MTU discovery. That is, it allows for user-mode MTU probing (or, packetization-layer path MTU discovery). This is particularly useful for diagnostic utilities, like traceroute/tracepath.

Switch ingress queueing back to use ingress_lock. qdisc_lock_tree now locks both the ingress and egress qdiscs on the device. All changes to data that might be used on both ingress and egress needs to be protected by using qdisc_lock_tree instead of manually taking dev->queue_lock. Additionally the qdisc stats_lock needs to be initialized to ingress_lock for ingress qdiscs. Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The attached patch adds gratuitous arp filtering, more precisely: it allows checking that the IPv4 source address matches the IPv4 destination address inside the ARP header. It also adds a check for the hardware address type when matching MAC addresses (nothing critical, just for better consistency).

This fixes an error in the calculation of t_ipi when X converges towards very low sending rates (between 1 and 64 bytes per second). Although this case may not sound likely, it can be reproduced by connecting, hitting enter (1 byte sent) and waiting for some time, during which the nofeedback timer halves the sending rate until finally it reaches the region 1..64 bytes/sec. Computing X is handled correctly (tested separately); but by dividing X _before_ entering the calculation of t_ipi, X becomes zero as a result. This in turn triggers a BUG condition caught in scaled_div(). Fixed by replacing with equivalent statement and explicit typecast for good measure. Calculation verified and effect of patch tested - reduced never below 1 byte per 64 seconds afterwards, i.e. not allowing divide-by-zero.

This patchset based on work by Aji_Srinivas@emc.com provides allows spanning tree to be controled from userspace. Like hotplug, it uses call_usermodehelper when spanning tree is enabled so there is no visible API change. If call to start usermode STP fails it falls back to existing kernel STP.

While in the STP learning state, don't route packets; wait until forwarding delay has expired. The purpose of the forwarding delay is to detect loops in the network, and if a brouter started up and started forwarding, it could cause a flood.

The skb transport pointer is currently used to specify the start of the checksum region for transmit checksum offload. Unfortunately, the same pointer is also used during receive side processing. This creates a problem when we want to retransmit a received packet with partial checksums since the skb transport pointer would be overwritten. This patch solves this problem by creating a new 16-bit csum_start offset value to replace the skb transport header for the purpose of checksums. This offset is calculated from skb->head so that it does not have to change when skb->data changes. No extra space is required since csum_offset itself fits within a 16-bit word so we can use the other 16 bits for csum_start. For backwards compatibility, just before we push a packet with partial checksums off into the device driver, we set the skb transport header to what it would have been under the old scheme.

esp_init_state doesn't account for the beet pseudo header in the header_len calculation, which may result in undersized skbs hitting xfrm4_beet_output, causing unnecessary reallocations in ip_finish_output2. The skbs should still always have enough room to avoid causing skb_under_panic in skb_push since we have at least 16 bytes available from LL_RESERVED_SPACE in xfrm_state_check_space.
