2009-10-29sky2: workarounds for Yukon-2 supremeStephen Hemminger
Changes related to support of Yukon supreme chip. Don't have this chip version to test on, these are reverse engineered from the vendor (GPL) driver. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-10-29sfc: Feed GRO result into RX allocation policy and interrupt moderationBen Hutchings
When GRO is successfully merging received packets, we should allocate raw page buffers rather than skbs that will be discarded by GRO. Otherwise, we should allocate skbs. GRO also benefits from higher interrupt moderation, so increase the score for mergeable RX packets. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2009-10-29net: Fix 'Re: PACKET_TX_RING: packet size is too long'Gabor Gombas
Currently PACKET_TX_RING forces certain amount of every frame to remain unused. This probably originates from an early version of the PACKET_TX_RING patch that in fact used the extra space when the (since removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled. The current code does not make any use of this extra space. This patch removes the extra space reservation and lets userspace make use of the full frame size.

2009-10-29net,socket: introduce DECLARE_SOCKADDR helper to catch overflow at build timeCyrill Gorcunov
proto_ops->getname implies copying protocol specific data into storage unit (particulary to __kernel_sockaddr_storage). So when we implement new protocol support we should keep such a detail in mind (which is easy to forget about). Lets introduce DECLARE_SOCKADDR helper which check if storage unit is not overfowed at build time. Eventually inet_getname is switched to use DECLARE_SOCKADDR (to show example of usage).

2009-10-29gigaset: fix bad assumptions about CAPI skbuffsTilman Schmidt
The CAPI interface incorrectly assumed that CAPI messages would always start at the beginning of the data buffer: fix by treating DATA_B3 messages as the link layer header to their payload data. This fix changes the way acknowledgement information is propagated through the hardware specific modules and thereby impacts the ISDN4Linux variant of the driver, too. Also some assumptions about methods not being called from interrupt context turned out to be unwarranted; fix by using dev_kfree_skb_any() wherever non-interrupt context isn't guaranteed.

I found that the current version of drivers/net/usb/dm9601.c can be used to successfully drive a low-power, low-cost network adapter with USB ID 0a46:9000, based on a DM9000E chipset.

2009-10-29AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2)Neil Horman
Augment raw_send_hdrinc to correct for incorrect ip header length values A series of oopses was reported to me recently. Apparently when using AF_RAW sockets to send data to peers that were reachable via ipsec encapsulation, people could panic or BUG halt their systems. I've tracked the problem down to user space sending an invalid ip header over an AF_RAW socket with IP_HDRINCL set to 1. Basically what happens is that userspace sends down an ip frame that includes only the header (no data), but sets the ip header ihl value to a large number, one that is larger than the total amount of data passed to the sendmsg call. In raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr that was passed in, but assume the data is all valid. Later during ipsec encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff to provide headroom for the ipsec headers. During this operation, the skb->transport_header is repointed to a spot computed by skb->network_header + the ip header length (ihl). Since so little data was passed in relative to the value of ihl provided by the raw socket, we point transport header to an unknown location, resulting in various crashes. This fix for this is pretty straightforward, simply validate the value of of iph->ihl when sending over a raw socket. If (iph->ihl*4U) > user data buffer size, drop the frame and return -EINVAL. I just confirmed this fixes the reported crashes. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-28bonding: fix a race condition in calls to slave MII ioctlsJiri Bohac
In mii monitor mode, bond_check_dev_link() calls the the ioctl handler of slave devices. It stores the ndo_do_ioctl function pointer to a static (!) ioctl variable and later uses it to call the handler with the IOCTL macro. If another thread executes bond_check_dev_link() at the same time (even with a different bond, which none of the locks prevent), a race condition occurs. If the two racing slaves have different drivers, this may result in one driver's ioctl handler being called with a pointer to a net_device controlled with a different driver, resulting in unpredictable breakage. Unless I am overlooking something, the "static" must be a copy'n'paste error (?). Signed-off-by: Jiri Bohac <jbohac@suse.cz> Signed-off-by: David S. Miller <davem@davemloft.net>
