Many if not all of these messages can be triggered by sending a few rogue frames which is trivially done and then we overflow our logs. Signed-off-by:

This fixes two issues with the key debugfs: 1) key index obviously isn't unique 2) various missing break statements led to bogus output Signed-off-by:

David Woodhouse noticed that under some circumstances the number of slab allocations kept growing. After looking a bit, this seemed to happen when you had a management mode interface that was *down*. The reason for this is that when the device is down, all management frames get queued to the in-kernel MLME (via ieee80211_sta_rx_mgmt) but then the sta work is invoked but doesn't run when the netif is down. When you then bring the interface up, all such frames are freed, but if you change the mode all of them are lost because the skb queue is reinitialised as soon as you go back to managed mode. The skb queue is correctly cleared when the interface is brought down, but the code doesn't account for the fact that it may be filled while it is not up. This patch should fix the issue by simply ignoring all interfaces that are down when going through the RX handlers. Signed-off-by:

This dongle does not follow the usb-irda specification, so it needs its own special driver. First, it uses control URBs for data transfer, instead of bulk or interrupt transfers; the only interrupt endpoint exposed seems to be a dummy to prevent the interface from being rejected. Second, it uses obfuscation and padding at the USB traffic level, for no apparent reason other than to make reverse engineering harder (full details on obfuscation in comments at beginning of source). Although it is advertised as a "4 Mbps FIR dongle", it apparently loses packets at speeds greater than 57600 bps. On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4959 . The Windows driver that is used normally to control this dongle has a filename of KS-959.SYS . Signed-off-by:

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:

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.

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:

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.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
