Add the Data Path Acceleration Architecture Frame Manger Driver. The FMan embeds a series of hardware blocks that implement a group of Ethernet interfaces. This patch adds The FMan configuration, initialization and runtime control routines. The FMan driver supports several hardware versions differentiated by things like: - Different type of MACs - Number of MAC and ports - Available resources - Different hardware errata Signed-off-by:

Add Frame Manager Multi-User RAM support. This internal FMan memory block is used by the FMan hardware modules, the management being made through the generic allocator. The FMan Internal memory, for example, is used for allocating transmit and receive FIFOs. Signed-off-by:

By moving stats update into iptunnel_xmit(), we can simplify iptunnel_xmit() usage. With this change there is no need to call another function (iptunnel_xmit_stats()) to update stats in tunnel xmit code path. Signed-off-by:

The 6320 family of switch chips has a second bank for statistics, but is missing three statistics in the port registers. Generalise and extend the code: * adding a field to the statistics table indicating the bank/register set where each statistics is. * add a function indicating if an individual statistics is available on this device * calculate at run time the sset_count. * return strings based on the available statistics of the device * return statistics based on the available statistics of the device * Add support for reading from the second bank.

Bert Kenward says: ==================== sfc: additional virtual function support This introduces the client side of a mechanism to defer authorisation of operations, for example multicast subscription. Although primarily aimed at SRIOV VFs this can also apply to unprivileged PFs. Also handle reboot ordering corner cases better and reduce the level of some logging. v2: remove #ifdef DEBUG around new WARN_ON in mcdi.c. ==================== Signed-off-by: -

There are situations - mostly reset related - where our view of the filter table differs from the hardware. In this case we may try and remove filters that aren't actually installed. This isn't that interesting in most situations, so downgrade the logging. Signed-off-by:

Bert Kenward authored
For unprivileged functions operations can be authorised by an admin function. Extra steps are introduced to the MCDI protocol in this situation - the initial response from the MCDI tells us that the operation has been deferred, and we must retry when told. We then receive an event telling us to retry. Note that this provides only the functionality for the unprivileged functions, not the handling of the administrative side. Signed-off-by:

After reboot the vswitch configuration from the PF may not be complete before the VF attempts to restore filters. In that case we see NO_EVB_PORT errors from the MC. Retry up to a time limit or until a different result is seen. Signed-off-by:

Check if the device get enough bandwidth from the entire PCI chain to satisfy its capabilities. This patch determines the PCIe device's bandwidth capabilities by reading its PCIe Link Capabilities registers and then call the pcie_get_minimum_link function to ensure that the adapter is hooked into a slot which is capable of providing the necessary bandwidth capabilities.

Florian Westphal says: ==================== tcp: honour SO_BINDTODEVICE for TW_RST case too This is V2, this time as a small series since I followed Erics advice to split this into smaller chunks, I hope this makes it easier to review. First patch adds inet_sk_transparent helper. Second patch contains an if/else swap that I split from the original TW_RST v1 one. Third patch is the actual change without the superfluous sock_net change. ==================== Signed-off-by: -

Hannes points out that when we generate tcp reset for timewait sockets we pretend we found no socket and pass NULL sk to tcp_vX_send_reset(). Make it cope with inet tw sockets and then provide tw sk. This makes RSTs appear on correct interface when SO_BINDTODEVICE is used. Packetdrill test case: // want default route to be used, we rely on BINDTODEVICE `ip route del 192.0.2.0/24 via 192.168.0.2 dev tun0` 0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 // test case still works due to BINDTODEVICE 0.001 setsockopt(3, SOL_SOCKET, SO_BINDTODEVICE, "tun0", 4) = 0 0.100...0.200 connect(3, ..., ...) = 0 0.100 > S 0:0(0) <mss 1460,sackOK,nop,nop> 0.200 < S. 0:0(0) ack 1 win 32792 <mss 1460,sackOK,nop,nop> 0.200 > . 1:1(0) ack 1 0.210 close(3) = 0 0.210 > F. 1:1(0) ack 1 win 29200 0.300 < . 1:1(0) ack 2 win 46 // more data while in FIN_WAIT2, expect RST 1.300 < P. 1:1001(1000) ack 1 win 46 // fails without this change -- default route is used 1.301 > R 1:1(0) win 0 Reported-by:

tcp_md5_do_lookup requires a full socket, so once we extend _send_reset() to also accept timewait socket we would have to change if (!sk && hash_location) to something like if ((!sk || !sk_fullsock(sk)) && hash_location) { ... } else { (sk && sk_fullsock(sk)) tcp_md5_do_lookup() } Switch the two branches: check if we have a socket first, then fall back to a listener lookup if we saw a md5 option (hash_location).

When closing a listen socket, tcp_abort currently calls tcp_done without clearing the request queue. If the socket has a child socket that is established but not yet accepted, the child socket is then left without a parent, causing a leak. Fix this by setting the socket state to TCP_CLOSE and calling inet_csk_listen_stop with the socket lock held, like tcp_close does. Tested using net_test. With this patch, calling SOCK_DESTROY on a listen socket that has an established but not yet accepted child socket results in the parent and the child being closed, such that they no longer appear in sock_diag dumps.

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2015-12-22 This series contains updates to fm10k only. Bruce cleans up the initialization of fm10k_workqueue at the global level, which fixes a checkpatch.pl error. Made several other cleanups of the driver, like making structures that do not change constant, remove unused code, cleanup code comments and use boolean states true/false instead of an integer since a bool is all that is needed. Jacob fixed the TLV format for little endian structures which are 4 byte aligned copy, so add an additional __aligned(4) and __packed to ensure that these structures are actually 4 byte aligned and packed correctly. Updated the driver to use ether_addr_equal() instead of memcmp() to compare MAC addresses. Alex Duyck cleans up the exception handling so all of the paths result in a similar state if we fail. Specifically the driver will now unload the mailbox interrupt, free the queue vectors and MSI-X, and then detach the interface. ==================== Signed-off-by: -
