Change the resume path to use pci write config for a couple of reasons: 1. pci_write_config_dword() allows for more error checking of PCI health after resume. 2. better to toggle this register on all chip types, since that is what vendor driver does. Signed-off-by:

The fec driver was enabling receive buffer descriptor without allocating the buffers. Make sure the buffer descriptors are initialized to not start receiving packets. Open also calls fec_restart after the rx buffers are allocated. With the code in fec_restart, it zeroes out the buffer descriptors that have just been setup. Signed-off-by:

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. Fix is to call cond_resched(), as we run in process context. Reported-by:

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:

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. Signed-off-by:

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.

Early on this was an experimental facility that few people other than Alexey Kuznetsov played with. Now it's a pretty fundamental thing and as people add more features to AF_PACKET sockets this config options creates ifdef spaghetti. So kill it off. Signed-off-by:

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. Signed-off-by:

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:
