2016-09-19ipvlan: Introduce l3s modeMahesh Bandewar1-1/+6
In a typical IPvlan L3 setup where master is in default-ns and each slave is into different (slave) ns. In this setup egress packet processing for traffic originating from slave-ns will hit all NF_HOOKs in slave-ns as well as default-ns. However same is not true for ingress processing. All these NF_HOOKs are hit only in the slave-ns skipping them in the default-ns. IPvlan in L3 mode is restrictive and if admins want to deploy iptables rules in default-ns, this asymmetric data path makes it impossible to do so. This patch makes use of the l3_rcv() (added as part of l3mdev enhancements) to perform input route lookup on RX packets without changing the skb->dev and then uses nf_hook at NF_INET_LOCAL_IN to change the skb->dev just before handing over skb to L4.

2016-09-01rxrpc: Don't expose skbs to in-kernel users [ver #2]David Howells1-41/+31
Don't expose skbs to in-kernel users, such as the AFS filesystem, but instead provide a notification hook the indicates that a call needs attention and another that indicates that there's a new call to be collected. This makes the following possibilities more achievable: (1) Call refcounting can be made simpler if skbs don't hold refs to calls. (2) skbs referring to non-data events will be able to be freed much sooner rather than being queued for AFS to pick up as rxrpc_kernel_recv_data will be able to consult the call state. (3) We can shortcut the receive phase when a call is remotely aborted because we don't have to go through all the packets to get to the one cancelling the operation. (4) It makes it easier to do encryption/decryption directly between AFS's buffers and sk_buffs. (5) Encryption/decryption can more easily be done in the AFS's thread contexts - usually that of the userspace process that issued a syscall - rather than in one of rxrpc's background threads on a workqueue. (6) AFS will be able to wait synchronously on a call inside AF_RXRPC. To make this work, the following interface function has been added: int rxrpc_kernel_recv_data( struct socket *sock, struct rxrpc_call *call, void *buffer, size_t bufsize, size_t *_offset, bool want_more, u32 *_abort_code); This is the recvmsg equivalent. It allows the caller to find out about the state of a specific call and to transfer received data into a buffer piecemeal. afs_extract_data() and rxrpc_kernel_recv_data() now do all the extraction logic between them. They don't wait synchronously yet because the socket lock needs to be dealt with. Five interface functions have been removed: rxrpc_kernel_is_data_last() rxrpc_kernel_get_abort_code() rxrpc_kernel_get_error_number() rxrpc_kernel_free_skb() rxrpc_kernel_data_consumed() As a temporary hack, sk_buffs going to an in-kernel call are queued on the rxrpc_call struct (->knlrecv_queue) rather than being handed over to the in-kernel user. To process the queue internally, a temporary function, temp_deliver_data() has been added. This will be replaced with common code between the rxrpc_recvmsg() path and the kernel_rxrpc_recv_data() path in a future patch.

Userspace can begin and suspend a transaction within the signal handler which means they might enter sys_rt_sigreturn() with the processor in suspended state. sys_rt_sigreturn() wants to restore process context (which may have been in a transaction before signal delivery). To do this it must restore TM SPRS. To achieve this, any transaction initiated within the signal frame must be discarded in order to be able to restore TM SPRs as TM SPRs can only be manipulated non-transactionally.. >From the PowerPC ISA: TM Bad Thing Exception [Category: Transactional Memory] An attempt is made to execute a mtspr targeting a TM register in other than Non-transactional state.

2016-08-26bridge: switchdev: Add forward mark support for stacked devicesIdo Schimmel1-9/+4
switchdev_port_fwd_mark_set() is used to set the 'offload_fwd_mark' of port netdevs so that packets being flooded by the device won't be flooded twice. It works by assigning a unique identifier (the ifindex of the first bridge port) to bridge ports sharing the same parent ID. This prevents packets from being flooded twice by the same switch, but will flood packets through bridge ports belonging to a different switch. This method is problematic when stacked devices are taken into account, such as VLANs. In such cases, a physical port netdev can have upper devices being members in two different bridges, thus requiring two different 'offload_fwd_mark's to be configured on the port netdev, which is impossible. The main problem is that packet and netdev marking is performed at the physical netdev level, whereas flooding occurs between bridge ports, which are not necessarily port netdevs. Instead, packet and netdev marking should really be done in the bridge driver with the switch driver only telling it which packets it already forwarded. The bridge driver will mark such packets using the mark assigned to the ingress bridge port and will prevent the packet from being forwarded through any bridge port sharing the same mark (i.e. having the same parent ID). Remove the current switchdev 'offload_fwd_mark' implementation and instead implement the proposed method. In addition, make rocker - the sole user of the mark - use the proposed method.

2016-08-24net: dsa: rename switch operations structureVivien Didelot1-5/+5
Now that the dsa_switch_driver structure contains only function pointers as it is supposed to, rename it to the more appropriate dsa_switch_ops, uniformly to any other operations structure in the kernel. No functional changes here, basically just the result of something like: s/dsa_switch_driver *drv/dsa_switch_ops *ops/g However keep the {un,}register_switch_driver functions and their dsa_switch_drivers list as is, since they represent the -- likely to be deprecated soon -- legacy DSA registration framework. In the meantime, also fix the following checks from checkpatch.pl to make it happy with this patch: CHECK: Comparison to NULL could be written "!ops" #403: FILE: net/dsa/dsa.c:470: + if (ops == NULL) { CHECK: Comparison to NULL could be written "ds->ops->get_strings" #773: FILE: net/dsa/slave.c:697: + if (ds->ops->get_strings != NULL) CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats" #824: FILE: net/dsa/slave.c:785: + if (ds->ops->get_ethtool_stats != NULL) CHECK: Comparison to NULL could be written "ds->ops->get_sset_count" #835: FILE: net/dsa/slave.c:798: + if (ds->ops->get_sset_count != NULL) total: 0 errors, 0 warnings, 4 checks, 784 lines checked Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
