switchdev: pass pointer to fib_info instead of copy

2016-06-24T17:21:59+00:00

[ Upstream commit da4ed55165d41b1073f9a476f1c18493e9bf8c8e ] The problem is that fib_info->nh is [0] so the struct fib_info allocation size depends on number of nexthops. If we just copy fib_info, we do not copy the nexthops info and driver accesses memory which is not ours. Given the fact that fib4 does not defer operations and therefore it does not need copy, just pass the pointer down to drivers as it was done before.

This drops API ncsi_stop_dev() as it does nothing. Signed-off-by: Gavin Shan Signed-off-by: Joel Stanley

net/ncsi: Enumerate NCSI channels in advance

2016-06-03T20:51:46+00:00

All NCSI packages and channels are enumerated when user brings up the interface. The enumeration is heavy task and consumes lots of time. We can just do it for once when considering the fact: NCSI physical topology won't change. This enumerates NCSI packages and channels when user activates the interface for the first time, meaing the procedure won't be revisited when user reactivates the interface. The time consumed by it will be saved and the response time is improved. In order for it, we replace ncsi_dev_config() with ncsi_dev_probe() that is triggered on first call to ncsi_start_dev(). Similarly, the NCSI packages and channels are not released in ncsi_stop_dev() which is triggered when the interface is closed. It means the release is postponed until the interface is unregistered.

net/ncsi: Manage NCSI device

2016-06-03T20:51:45+00:00

There are multiple packages and channels connecting to NCSI enabled interface. The available packages and channels are probed with NCSI packets when NCSI device is started. Among the available packages and channels, only one channel should be selected to be active to provide service. When the active channel enters to failure state, we need choose another channel as active one to do failover. This implements the state machine to support above tasks. Also, the public interfaces are exposed for NIC driver to manage NCSI device. Signed-off-by: Gavin Shan Signed-off-by: Joel Stanley

net/ncsi: Resource management

2016-06-03T20:51:43+00:00

According to NCSI spec (DSP0222), the NCSI enabled interface can connected to multiple packages simultaneously, up to 8 packages. Each package includes multiple channels, up to 32 channels. At one moment, one channel is enabled to provide service to the NCSI enabled interface. Besides, each channel comprises capabilities, modes, filters, version and statistics etc. All of them are resources to NCSI protocol stack. At the meanwhile, the NCSI device seen from NIC driver is represented by "struct ncsi_dev", which is expected to populated and started by NIC driver before the NIC can work. All possible NCSI packages and NCSI channels connected to the NCSI interface are tracked from the NCSI device. Also, the NCSI device recognizes active channel that is currently providing service to NCSI enabled interface. Also, the NCSI requests (pairs of command and response) are embedded in NCSI device. This introduces the data structs to represents the NCSI resources mentioned as above. Also, functions used by NCSI stack internally are implemented. Besides, this introduces kernel config option CONFIG_NET_NCSI to enable NCSI stack. Signed-off-by: Gavin Shan

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec

2016-05-04T20:35:31+00:00

Steffen Klassert says: ==================== pull request (net): ipsec 2016-05-04 1) The flowcache can hit an OOM condition if too many entries are in the gc_list. Fix this by counting the entries in the gc_list and refuse new allocations if the value is too high. 2) The inner headers are invalid after a xfrm transformation, so reset the skb encapsulation field to ensure nobody tries access the inner headers. Otherwise tunnel devices stacked on top of xfrm may build the outer headers based on wrong informations. 3) Add pmtu handling to vti, we need it to report pmtu informations for local generated packets. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller

vxlan: Add checksum check to the features check function

2016-05-03T20:00:54+00:00

We need to perform an additional check on the inner headers to determine if we can offload the checksum for them. Previously this check didn't occur so we would generate an invalid frame in the case of an IPv6 header encapsulated inside of an IPv4 tunnel. To fix this I added a secondary check to vxlan_features_check so that we can verify that we can offload the inner checksum. Signed-off-by: Alexander Duyck Signed-off-by: David S. Miller

switchdev: Adding complete operation to deferred switchdev ops

2016-04-24T18:23:32+00:00

When using switchdev deferred operation (SWITCHDEV_F_DEFER), the operation is executed in different context and the application doesn't have any way to get the operation real status. Adding a completion callback fixes that. This patch adds fields to switchdev_attr and switchdev_obj "complete_priv" field which is used by the "complete" callback. Application can set a complete function which will be called once the operation executed.
