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.

Currently in process_backlog(), the process_queue dequeuing is performed with local IRQ disabled, to protect against flush_backlog(), which runs in hard IRQ context. This patch moves the flush operation to a work queue and runs the callback with bottom half disabled to protect the process_queue against dequeuing. Since process_queue is now always manipulated in bottom half context, the irq disable/enable pair around the dequeue operation are removed. To keep the flush time as low as possible, the flush works are scheduled on all online cpu simultaneously, using the high priority work-queue and statically allocated, per cpu, work structs. Overall this change increases the time required to destroy a device to improve slightly the packets reinjection performances.

This allows a privileged process to filter by socket mark when dumping sockets via INET_DIAG_BY_FAMILY. This is useful on systems that use mark-based routing such as Android.

由 Yuval Mintz 提交于
When ndo_set_rx_mode() is called for bnx2x, as part of process of configuring the new MAC address filters [both unicast & multicast] driver begins by flushing the existing configuration and then iterating over the network device's list of addresses and configures those instead. This has the side-effect of creating a short gap where traffic wouldn't be properly classified, as no filters are configured in HW. While for unicasts this is rather insignificant [as unicast MACs don't frequently change while interface is actually running], for multicast traffic it does pose an issue as there are multicast-based networks where new multicast groups would constantly be removed and added. This patch tries to remedy this [at least for the newer adapters] - Instead of flushing & reconfiguring all existing multicast filters, the driver would instead create the approximate hash match that would result from the required filters. It would then compare it against the currently configured approximate hash match, and only add and remove the delta between those.

Merge tag 'rxrpc-rewrite-20160824-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Add better client conn management strategy These two patches add a better client connection management strategy. They need to be applied on top of the just-posted fixes. (1) Duplicate the connection list and separate out procfs iteration from garbage collection. This is necessary for the next patch as with that client connections no longer appear on a single list and may not appear on a list at all - and really don't want to be exposed to the old garbage collector. (Note that client conns aren't left dangling, they're also in a tree rooted in the local endpoint so that they can be found by a user wanting to make a new client call. Service conns do not appear in this tree.) (2) Implement a better lifetime management and garbage collection strategy for client connections. In this, a client connection can be in one of five cache states (inactive, waiting, active, culled and idle). Limits are set on the number of client conns that may be active at any one time and makes users wait if they want to start a new call when there isn't capacity available. To make capacity available, active and idle connections can be culled, after a short delay (to allow for retransmission). The delay is reduced if the capacity exceeds a tunable threshold. If there is spare capacity, client conns are permitted to hang around a fair bit longer (tunable) so as to allow reuse of negotiated security contexts. After this patch, the client conn strategy is separate from that of service conns (which continues to use the old code for the moment). This difference in strategy is because the client side retains control over when it allows a connection to become active, whereas the service side has no control over when it sees a new connection or a new call on an old connection. ==================== Signed-off-by: NDavid S.

Merge tag 'rxrpc-rewrite-20160824-1' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: More fixes Here are a couple of fix patches: (1) Fix the conn-based retransmission patch posted yesterday. This breaks if it actually has to retransmit. However, it seems the likelihood of this happening is really low, despite the server I'm testing against being located >3000 miles away, and sometime of the time it's handled in the call background processor before we manage to disconnect the call - hence why I didn't spot it.

Before commit 99724c18 ("mlxsw: spectrum: Introduce support for router interfaces") we used to assign vFIDs to the created vPorts. Since these vPorts were used for slow path traffic we had to disable learning for them, as it doesn't make sense to have it enabled. This is no longer the case and now vPorts are either used for router interfaces (for which learning is disabled by the firmware) or bridge ports (for which learning is explicitly enabled by the driver). Therefore, we can remove the learning configuration upon vPort creation. Signed-off-by: NIdo Schimmel <idosch@mellanox.com> Signed-off-by: NJiri Pirko <jiri@mellanox.com> Signed-off-by: NDavid S.

Up until now we simply stored the learning configuration of a bridge port in the driver and decided whether to learn a new FDB record based on this value.

Instead, offload the learning configuration to the device, thereby preventing it from generating notifications when learning is disabled.

Up until now a learning session ended whenever the number of queried records was zero. This turned out to be problematic in situations where a large number of MACs (48K) had to be processed by the switch driver, as RTNL mutex is held during the learning session. Instead, limit the number of FDB records that can be processed in a session to 64. This means that every time the device is queried for learning notifications (currently, every 100ms), up to 64 records will be processed by the switch driver.

Improve the management and caching of client rxrpc connection objects. From this point, client connections will be managed separately from service connections because AF_RXRPC controls the creation and re-use of client connections but doesn't have that luxury with service connections. Further, there will be limits on the numbers of client connections that may be live on a machine. No direct restriction will be placed on the number of client calls, excepting that each client connection can support a maximum of four concurrent calls. Note that, for a number of reasons, we don't want to simply discard a client connection as soon as the last call is apparently finished: (1) Security is negotiated per-connection and the context is then shared between all calls on that connection. The context can be negotiated again if the connection lapses, but that involves holding up calls whilst at least two packets are exchanged and various crypto bits are performed - so we'd ideally like to cache it for a little while at least. (2) If a packet goes astray, we will need to retransmit a final ACK or ABORT packet. To make this work, we need to keep around the connection details for a little while. (3) The locally held structures represent some amount of setup time, to be weighed against their occupation of memory when idle. To this end, the client connection cache is managed by a state machine on each connection. There are five states: (1) INACTIVE - The connection is not held in any list and may not have been exposed to the world. If it has been previously exposed, it was discarded from the idle list after expiring. (2) WAITING - The connection is waiting for the number of client conns to drop below the maximum capacity. Calls may be in progress upon it from when it was active and got culled. The connection is on the rxrpc_waiting_client_conns list which is kept in to-be-granted order. Culled conns with waiters go to the back of the queue just like new conns. (3) ACTIVE - The connection has at least one call in progress upon it, it may freely grant available channels to new calls and calls may be waiting on it for channels to become available. The connection is on the rxrpc_active_client_conns list which is kept in activation order for culling purposes. (4) CULLED - The connection got summarily culled to try and free up capacity. Calls currently in progress on the connection are allowed to continue, but new calls will have to wait. There can be no waiters in this state - the conn would have to go to the WAITING state instead. (5) IDLE - The connection has no calls in progress upon it and must have been exposed to the world (ie. the EXPOSED flag must be set). When it expires, the EXPOSED flag is cleared and the connection transitions to the INACTIVE state. The connection is on the rxrpc_idle_client_conns list which is kept in order of how soon they'll expire. A connection in the ACTIVE or CULLED state must have at least one active call upon it; if in the WAITING state it may have active calls upon it; other states may not have active calls. As long as a connection remains active and doesn't get culled, it may continue to process calls - even if there are connections on the wait queue. This simplifies things a bit and reduces the amount of checking we need do. There are a couple flags of relevance to the cache: (1) EXPOSED - The connection ID got exposed to the world. If this flag is set, an extra ref is added to the connection preventing it from being reaped when it has no calls outstanding. This flag is cleared and the ref dropped when a conn is discarded from the idle list. (2) DONT_REUSE - The connection should be discarded as soon as possible and should not be reused. This commit also provides a number of new settings: (*) /proc/net/rxrpc/max_client_conns The maximum number of live client connections. Above this number, new connections get added to the wait list and must wait for an active conn to be culled. Culled connections can be reused, but they will go to the back of the wait list and have to wait. (*) /proc/net/rxrpc/reap_client_conns If the number of desired connections exceeds the maximum above, the active connection list will be culled until there are only this many left in it. (*) /proc/net/rxrpc/idle_conn_expiry The normal expiry time for a client connection, provided there are fewer than reap_client_conns of them around. (*) /proc/net/rxrpc/idle_conn_fast_expiry The expedited expiry time, used when there are more than reap_client_conns of them around. Note that I combined the Tx wait queue with the channel grant wait queue to save space as only one of these should be in use at once. Note also that, for the moment, the service connection cache still uses the old connection management code. Signed-off-by: NDavid Howells <dhowells@redhat.com>

The main connection list is used for two independent purposes: primarily it is used to find connections to reap and secondarily it is used to list connections in procfs. Split the procfs list out from the reap list. This allows us to stop using the reap list for client connections when they acquire a separate management strategy from service collections. The client connections will not be on a management single list, and sometimes won't be on a management list at all. This doesn't leave them floating, however, as they will also be on an rb-tree rooted on the socket so that the socket can find them to dispatch calls.

If a duplicate packet comes in for a call that has just completed on a connection's channel then there will be an oops in the data_ready handler because it tries to examine the connection struct via a call struct (which we don't have - the pointer is unset). Since the connection struct pointer is available to us, go direct instead. Also, the ACK packet to be retransmitted needs three octets of padding between the soft ack list and the ackinfo.
