2015-08-29netfilter: nfnetlink: work around wrong endianess in res_id fieldPablo Neira Ayuso
The convention in nfnetlink is to use network byte order in every header field as well as in the attribute payload. The initial version of the batching infrastructure assumes that res_id comes in host byte order though. The only client of the batching infrastructure is nf_tables, so let's add a workaround to address this inconsistency. We currently have 11 nfnetlink subsystems according to NFNL_SUBSYS_COUNT, so we can assume that the subsystem 2560, ie. htons(10), will not be allocated anytime soon, so it can be an alias of nf_tables from the nfnetlink batching path when interpreting the res_id field. Based on original patch from Florian Westphal. Reported-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2015-08-28sfc: Allow driver to cope with a lower number of VIs than it needs for RSSShradha Shah
Previously, the driver would refuse to load if it couldn't secure enough VIs from the MC to fulfill its RSS requirements. This was causing probe to fail on later functions in configurations where we'd run out of VIs, such as having many VFs. This change allows the driver to load with fewer VIs, down to a minimum of 2. A warning will be printed saying that RSS requirements were not met, possibly affecting performance. efx->max_tx_channels needs to be set to avoid going down the failure path in efx_probe_nic() immediately in the loop after the probe() NIC-type function. Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack of VIs. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-28IGMP: Inhibit reports for local multicast groupsPhilip Downey
The range of addresses between 224.0.0.0 and 224.0.0.255 inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting. Multicast routers should not forward any multicast datagram with destination addresses in this range, regardless of its TTL. Currently, IGMP reports are generated for this reserved range of addresses even though a router will ignore this information since it has no purpose. However, the presence of reserved group addresses in an IGMP membership report uses up network bandwidth and can also obscure addresses of interest when inspecting membership reports using packet inspection or debug messages. Although the RFCs for the various version of IGMP (e.g.RFC 3376 for v3) do not specify that the reserved addresses be excluded from membership reports, it should do no harm in doing so. In particular there should be no adverse effect in any IGMP snooping functionality since 224.0.0.x is specifically excluded as per RFC 4541 (IGMP and MLD Snooping Switches Considerations) section 2.1.2. Data Forwarding Rules: 2) Packets with a destination IP (DIP) address in the 224.0.0.X range which are not IGMP must be forwarded on all ports. IGMP reports for local multicast groups can now be optionally inhibited by means of a system control variable (by setting the value to zero) e.g.: echo 0 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports To retain backwards compatibility the previous behaviour is retained by default on system boot or reverted by setting the value back to non-zero e.g.: echo 1 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports Signed-off-by: Philip Downey <pdowney@brocade.com> Signed-off-by: David S.

2015-08-28r8169: Add software counter for multicast packagesCorinna Vinschen
The multicast hardware counter on 8168/8111 chips is only 32 bit while the statistics in struct rtnl_link_stats64 are 64 bit. Given that statistics are requested on an irregular basis, an overflow of the hardware counter can go unnoticed. To count even very large numbers of multicast packets reliably, add a software counter and remove previously applied code to fill the multicast field requested by @rtl8169_get_stats64 with the values read from the rx_multicast hardware counter.

Synchronous connections are initially created with type eSCO. Link manager may reject proposed link parameters, which triggers connection setup retry with a different set. Link type embedded in responses should be disregarded until Synchronous Connect Complete returns Success (0x00). Current code updates link type every time which creates an issue when link type changes to SCO and back to eSCO on further attepts.

2015-08-28Bluetooth: hci_intel: Add support for platform driverLoic Poulain
A platform device can be used to provide some specific resources in order to manage the controller. In this first patch we retrieve the reset gpio which is used to power on/off the controller. The main issue is to match the current tty with the correct pdev. In case of ACPI, we can easily find the right tty/pdev pair because they are both child of the same UART port. If controller is powered-on from the driver, we need to wait for a HCI boot event before being able to send any command.

2015-08-28Bluetooth: hci_intel: Add Intel baudrate configuration supportLoic Poulain
Implement the set_baudrate callback for hci_intel. - Controller requires a read Intel version command before updating its baudrate. - The operation consists in an async cmd since the controller does not respond at the same speed. - Wait 100ms to let the controller change its baudrate. - Clear RTS until we change our own UART speed Manage speed change in the setup function, we need to restore the oper speed once chip has booted on patched firmware.

2015-08-28Bluetooth: hci_uart: Fix zero len data packet reception issueLoic Poulain
Packets with a variable length value equal to zero were not received. Since no more data expected (and input buffer entirely consumed), we need to complete/forward the packet immediately instead of waiting for more data.

2015-08-28nl802154: stricter input checking for boolean inputsStefan Schmidt
So far we handled boolean input by forcing them with !! and assigning them into a bool. This allowed userspace to send values > 1 which were used as 1. We should be stricter here and return -EINVAL for all but 0 or 1.

2015-08-28Bluetooth: Make the function sco_conn_del have a return type of voidNicholas Krause
This makes the function sco_conn_del have a return type of void now due to this function always running successfully and thus never needing to signal its caller when a non recoverable internal failure occurs by returning a error code to its respective caller.
