This patch removes connection tracking handling for ICMPv6 messages related to Stateless Address Autoconfiguration, MLD, and MLDv2. They can not be tracked because they are massively using multicast (on pre-defined address). But they are not invalid and should not be detected as such. Signed-off-by:

The patch fixes a typo in the inverse mapping of Node Information request. Following draft-ietf-ipngwg-icmp-name-lookups-09, "Querier" sends a type 139 (ICMPV6_NI_QUERY) packet to "Responder" which answer with a type 140 (ICMPV6_NI_REPLY) packet. Signed-off-by:

Tap devices can make use of a small MAC filter set via the TUNSETTXFILTER ioctl. The filter has a set of exact matches plus a hash for imperfect filtering of additional multicast addresses. The current code is unbalanced, adding unicast addresses to the multicast hash, but only checking the hash against multicast addresses. This results in the filter dropping unicast addresses that overflow the exact filter. The fix is simply to disable the filter by leaving count set to zero if we find non-multicast addresses after the exact match table is filled. Signed-off-by:

Unfortunately, the OF device tree nodes for SBUS and PCI hme devices have the same device node name on some systems. So if the name of the parent node isn't 'sbus', skip it. Based upon an excellent report and detective work by Meelis Roos and Eric Brower. Signed-off-by:

From: Ondrej Zary <linux@rainbow-software.org> last year, I posted a patch which fixed hibernation on 3c509 cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I stopped using hibernation (as it did not work with my new IT8212 RAID controller). Now I fixed it and noticed that 3c509 does not wake up properly anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig down/up makes the card work again in PnP mode. However, in ISA mode, ifconfig up ends with "No such device" error. Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only some statistics-related change. So the cause of the problem must be somewhere else. This patch makes the resume work in PnP mode, but it's still not enough for ISA mode. Signed-off-by: -

From: Ilkka Virta <itvirta@iki.fi> In the lockup situation the driver seems to go off in an eternal storm of interrupts right after calling request_irq(). It doesn't actually do anything interesting in the interrupt handler. Since connecting the link afterwards works, something later in initialization must fix this. Looking at gem_do_start() and gem_open(), it seems that the only thing done while opening the device after the request_irq(), is a call to napi_enable(). I don't know what the ordering requirements are for the initialization, but I boldly tried to move the napi_enable() call inside gem_do_start() before the link state is checked and interrupts subsequently enabled, and it seems to work for me. Doesn't even break anything too obvious... Signed-off-by: -

Some Realtek chips (RTL8169sb/8110sb in my case) are unable to retrieve ethtool statistics when the interface is down. The process stays in endless loop in rtl8169_get_ethtool_stats. This is because these chips need to have receiver enabled (CmdRxEnb bit in ChipCmd register) that is cleared when the interface is going down. It's better to update statistics only when the interface is up and otherwise return copy of statistics grabbed when the interface was up (in rtl8169_close). It is interesting that PCI-E NICs (like 8168b/8111b...) are not affected. Signed-off-by:

Like the UDP header fix, pskb_may_pull() can potentially alter the SKB buffer. Thus the saddr and daddr, pointers may point to the old skb->data buffer. I haven't seen corruptions, as its only seen if the old skb->data buffer were reallocated by another user and written into very quickly (or poison'd by SLAB debugging). Signed-off-by:

The UDP header pointer assignment must happen after calling pskb_may_pull(). As pskb_may_pull() can potentially alter the SKB buffer. This was exposted by running multicast traffic through the NIU driver, as it won't prepull the protocol headers into the linear area on receive. Signed-off-by:

This patch adds a few device ID's. It also removes an ID that was used in an internal engineering version of a device and will never see commercial light. Even if this ID will be 'recycled' in the future, which is very unlikely, we don't know what kind of device will be behind it. Therefore it's safer to remove it. Signed-off-by:
