Kernel bugzilla #15239 On some workloads, it is quite possible to get a huge dst list to process in dst_gc_task(), and trigger soft lockup detection.

As noticed by Jon Masters <jonathan@jonmasters.org>, the conntrack hash size is global and not per namespace, but modifiable at runtime through /sys/module/nf_conntrack/hashsize. Changing the hash size will only resize the hash in the current namespace however, so other namespaces will use an invalid hash size. This can cause crashes when enlarging the hashsize, or false negative lookups when shrinking it. Move the hash size into the per-namespace data and only use the global hash size to initialize the per-namespace value when instanciating a new namespace. Additionally restrict hash resizing to init_net for now as other namespaces are not handled currently. Cc: stable@kernel.org Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S.

nf_conntrack_cachep is currently shared by all netns instances, but because of SLAB_DESTROY_BY_RCU special semantics, this is wrong. If we use a shared slab cache, one object can instantly flight between one hash table (netns ONE) to another one (netns TWO), and concurrent reader (doing a lookup in netns ONE, 'finding' an object of netns TWO) can be fooled without notice, because no RCU grace period has to be observed between object freeing and its reuse. We dont have this problem with UDP/TCP slab caches because TCP/UDP hashtables are global to the machine (and each object has a pointer to its netns). If we use per netns conntrack hash tables, we also *must* use per netns conntrack slab caches, to guarantee an object can not escape from one namespace to another one.

As discovered by Jon Masters <jonathan@jonmasters.org>, the "untracked" conntrack, which is located in the data section, might be accidentally freed when a new namespace is instantiated while the untracked conntrack is attached to a skb because the reference count it re-initialized. The best fix would be to use a seperate untracked conntrack per namespace since it includes a namespace pointer. Unfortunately this is not possible without larger changes since the namespace is not easily available everywhere we need it. For now move the untracked conntrack initialization to the init_net setup function to make sure the reference count is not re-initialized and handle cleanup in the init_net cleanup function to make sure namespaces can exit properly while the untracked conntrack is in use in other namespaces.

The report descriptor is read by user space (via the Service Discovery Protocol), so it is only available during the ioctl to connect. However, the HID probe function that needs the descriptor might not be called until a specific module is loaded. Keep a copy of the descriptor so it is available for later use.

This patch adds GSO/checksum offload to af_packet sockets using virtio_net_hdr. Based on Rusty's patch to add this support to tun. It allows GSO/checksum offload to be enabled when using raw socket backend with virtio_net. Adds PACKET_VNET_HDR socket option to prepend virtio_net_hdr in the receive path and process/skip virtio_net_hdr in the send path. This option is only allowed with SOCK_RAW sockets attached to ethernet type devices. v2 updates ---------- Michael's Comments - Perform length check in packet_snd() when GSO is off even when vnet_hdr is present. - Check for SKB_GSO_FCOE type and return -EINVAL - don't allow tx/rx ring when vnet_hdr is enabled. Herbert's Comments - Removed ethernet specific code. - protocol value is assumed to be passed in by the caller. Signed-off-by: NSridhar Samudrala <sri@us.ibm.com> Signed-off-by: NDavid S.

This patch introduces the similar helpers as those already done for uc list. However multicast lists are no list_head lists but "mademanually". The three macros added by this patch will make the transition of mc_list to list_head smooth in two steps: 1) convert all drivers to use these macros (with the original iterator of type "struct dev_mc_list") 2) once all drivers are converted, convert list type and iterators to "struct netdev_hw_addr" in one patch. >From now on, drivers can (and should) use "netdev_for_each_mc_addr" to iterate over the addresses with iterator of type "struct netdev_hw_addr". Also macros "netdev_mc_count" and "netdev_mc_empty" to read list's length. This is the state which should be reached in all drivers.

This change corrects an issue that will cause false hangs when using either 82575 or 82580 in legacy interrupt mode. The issue is caused when there is a slow traffic flow and an "ethtool -r" is executed while using legacy or MSI interrupts. MSI-X is not affected by this issue due to the fact that we were already reconfiguring the vectors after reset. If possible it would be best to push this for net-2.6 since it is resolving a bug but if that is not possible then net-next-2.6 will be fine.
