2007-10-10[IrDA]: Kingsun Dazzle IrDA USB driverAlex Villacís Lasso3-0/+836
This dongle does not follow the usb-irda specification, so it needs its own special driver. Just like the Kingsun/Donshine dongle, it exposes two interrupt endpoints. Reception is performed through direct reads from the input endpoint. Transmission requires splitting the IrDA frames into 8-byte segments, in which the first byte encodes how many of the remaining 7 bytes are used as data. Speed change is made with a control URB just like the one in cypress_m8, and it seems to support up to 115200 bps. On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4100 Signed-off-by: Alex Villacís Lasso <a_villacis@palosanto.com> Signed-off-by: Samuel Ortiz <samuel@sortiz.org> Signed-off-by: David S.

2007-10-10[NET]: DIV_ROUND_UP cleanup (part two)Ilpo Järvinen10-16/+21
Hopefully captured all single statement cases under net/. I'm not too sure if there is some policy about #includes that are "guaranteed" (ie., in the current tree) to be available through some other #included header, so I just added linux/kernel.h to each changed file that didn't #include it previously.

2007-10-10[IPV4] IPSEC: Omit redirect for tunnelled packet.Masahide NAKAMURA1-1/+1
IPv4 IPsec tunnel gateway incorrectly sends redirect to sender if it is onlink host when network device the IPsec tunnelled packet is arrived is the same as the one the decapsulated packet is sent. With this patch, it omits to send the redirect when the forwarding skbuff carries secpath, since such skbuff should be assumed as a decapsulated packet from IPsec tunnel by own. Request for comments: Alternatively we'd have another way to change net/ipv4/route.c (__mkroute_input) to use RTCF_DOREDIRECT flag unless skbuff has no secpath. It is better than this patch at performance point of view because IPv4 redirect judgement is done at routing slow-path. However, it should be taken care of resource changes between SAD(XFRM states) and routing table. In other words, When IPv4 SAD is changed does the related routing entry go to its slow-path? If not, it is reasonable to apply this patch. Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[IPV6] IPSEC: Omit redirect for tunnelled packet.Masahide NAKAMURA1-1/+3
IPv6 IPsec tunnel gateway incorrectly sends redirect to router or sender when network device the IPsec tunnelled packet is arrived is the same as the one the decapsulated packet is sent. With this patch, it omits to send the redirect when the forwarding skbuff carries secpath, since such skbuff should be assumed as a decapsulated packet from IPsec tunnel by own. It may be a rare case for an IPsec security gateway, however it is not rare when the gateway is MIPv6 Home Agent since the another tunnel end-point is Mobile Node and it changes the attached network.

2007-10-10[IPV6] XFRM: Fix connected socket to use transformation.Noriaki TAKAMIYA2-2/+41
When XFRM policy and state are ready after TCP connection is started, the traffic should be transformed immediately, however it does not on IPv6 TCP. It depends on a dst cache replacement policy with connected socket. It seems that the replacement is always done for IPv4, however, on IPv6 case it is done only when routing cookie is changed. This patch fix that non-transformation dst can be changed to transformation one. This behavior is required by MIPv6 and improves IPv6 IPsec. Fixes by Masahide NAKAMURA.

2007-10-10[TCP] MIB: Add counters for discarded SACK blocksIlpo Järvinen3-1/+15
In DSACK case, some events are not extraordinary, such as packet duplication generated DSACK. They can arrive easily below snd_una when undo_marker is not set (TCP being in CA_Open), counting such DSACKs amoung SACK discards will likely just mislead if they occur in some scenario when there are other problems as well. Similarly, excessively delayed packets could cause "normal" DSACKs. Therefore, separate counters are allocated for DSACK events.

2007-10-10[TCP]: Discard fuzzy SACK blocksIlpo Järvinen1-0/+82
SACK processing code has been a sort of russian roulette as no validation of SACK blocks is previously attempted. Besides, it is not very clear what all kinds of broken SACK blocks really mean (e.g., one that has start and end sequence numbers reversed). So now close the roulette once and for all.
