Current IPv6 implementation uses inetpeer to store metrics for routes. The problem of inetpeer is that it doesn't take subnet prefix length in to consideration. If two routes have the same address but different prefix length, they share same inetpeer. So changing metrics of one route also affects the other. The fix is to allocate separate metrics storage for each route. Signed-off-by:

The externs here didn't agree with the declarations in qos.c. Better would be probably to move this into a header, but since it's common practice to have naked externs with sysctls I left it for now. Cc: samuel@sortiz.org Signed-off-by:

Commit bd30ce4b (caif: Use RCU instead of spin-lock in caif_dev.c) added a potential NULL dereference in case alloc_percpu() fails. caif_device_alloc() can also use GFP_KERNEL instead of GFP_ATOMIC. Signed-off-by:

Attempt to reduce the number of IP packets emitted in response to single SCTP packet (2e3216cd) introduced a complication - if a packet contains two COOKIE_ECHO chunks and nothing else then SCTP state machine corks the socket while processing first COOKIE_ECHO and then loses the association and forgets to uncork the socket. To deal with the issue add new SCTP command which can be used to set association explictly. Use this new command when processing second COOKIE_ECHO chunk to restore the context for SCTP state machine. Signed-off-by:

Fix a number of issues in ibmveth_set_csum_offload: - set_attr6 and clr_attr6 may be used uninitialised - We store the result of the IPV4 checksum change in ret but overwrite it in a couple of places before checking it again later. Add ret4 to make it obvious what we are doing. - We weren't clearing the NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM flags if the enable of that hypervisor feature failed. Signed-off-by:

descs[].fields.address is 32bit which truncates any dma mapping errors so dma_mapping_error() fails to catch it. Use a dma_addr_t to do the comparison. With this patch I was able to transfer many gigabytes of data with IOMMU fault injection set at 10% probability. Signed-off-by:

d8873315 introduced the IFF_SKB_TX_SHARING flag, which I unilaterally set in ether_setup. In doing this I didn't realize that other flags (such as IFF_XMIT_DST_RELEASE) might be set prior to calling the ether_setup routine. This patch changes ether_setup to or in SKB_TX_SHARING so as not to inadvertently clear other existing flags. Thanks to Pekka Riikonen for pointing out my error Signed-off-by:

dev_forward_skb loops an skb back into host networking stack which might hang on the memory indefinitely. In particular, this can happen in macvtap in bridged mode. Copy the userspace fragments to avoid blocking the sender in that case. As this patch makes skb_copy_ubufs extern now, I also added some documentation and made it clear the SKBTX_DEV_ZEROCOPY flag automatically instead of doing it in all callers. This can be made into a separate patch if people feel it's worth it. Signed-off-by:

flow_cache_lookup will return a cached object (or null pointer) that the resolver (i.e. xfrm_policy_lookup) previously found for another namespace using the same key/family/dir. Instead, make the namespace part of what identifies entries in the cache. As before, flow_entry_valid will return 0 for entries where the namespace has been deleted, and they will be removed from the cache the next time flow_cache_gc_task is run. Reported-by:
