2012-04-20atl1c: add module parameter for l1c_wait_until_idleHuang, Xiong2-15/+24
l1c_wait_until_idle is called for serval modules (TXQ/RXQ/TXMAC/RXMAC). specific moudle have specific idle/busy status in reg REG_IDLE_STATUS. the previous code return wrongly if all modules are in idle status, regardless the 'stop' action is applied on individual module. Refine the reg REG_IDLE_STATUS definition as well. Signed-off-by: xiong <xiong@qca.qualcomm.com> Tested-by: Liu David <dwliu@qca.qualcomm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-04-20stmmac: do not fail when probe and there is no csr clk definedGiuseppe CAVALLARO2-7/+11
On some platforms, for example where we are doing the bring-up, the csr clock is not passed from the framework and the Ethernet device driver is failing when it can work w/o any issues and using the default values. So this patch just warnings the case of the csr clock cannot be acquired but w/o failing the probe step. I have just tested it on ST STiH415 SoC (ARM).

2012-04-20stmmac: verify the dma_cfg platform fieldsGiuseppe CAVALLARO4-7/+25
Recently the dma parameters that can be passed from the platform have been moved from the plat_stmmacenet_data to the stmmac_dma_cfg. In case of this new structure is not well allocated the driver can fails. This is an example how this field is managed in ST platforms static struct stmmac_dma_cfg gmac_dma_setting = { .pbl = 32, }; static struct plat_stmmacenet_data stih415_ethernet_platform_data[] = { { .dma_cfg = &gmac_dma_setting, .has_gmac = 1, [snip] This patch so verifies that the dma_cfg passed from the platform. In case of it is NULL there is no reason that the driver has to fail and some default values can be passed. These are ok for all the Synopsys chips and could impact on performances, only.

2012-04-19tipc: Ensure network address change doesn't impact configuration serviceAllan Stephens1-1/+1
Enhances command validation done by TIPC's configuration service so that it works properly even if the node's network address is changed in mid-operation.

Revises handling of a rejected message to ensure that a locally originated message is returned properly even if the node's network address is changed in mid-operation.

2012-04-19tipc: properly handle off-node send requests with invalid addrAllan Stephens1-2/+9

2012-04-19tipc: take lock while updating node network addressAllan Stephens1-1/+2
The routine that changes the node's network address now takes TIPC's network lock in write mode while the main address variable and associated data structures are being changed; this is needed to ensure that the link subsystem won't attempt to send a message off-node until the sending port's message header template has been updated with the node's new network address.

2012-04-19tipc: Ensure network address change doesn't impact local connectionsAllan Stephens4-31/+34
Revises routines that deal with connections between two ports on the same node to ensure the connection is not impacted if the node's network address is changed in mid-operation. The routines now treat the default node address of <0.0.0> as an alias for "this node" in the following situations: 1) Incoming messages destined to a connected port now handle the alias properly when validating that the message was sent by the expected peer port, ensuring that the message will be accepted regardless of whether it specifies the node's old network address or it's current one. 2) The code which completes connection establishment now handles the alias properly when determining if the peer port is on the same node as the connected port. An added benefit of addressing issue 1) is that some peer port validation code has been relocated to TIPC's socket subsystem, which means that validation is no longer done twice when a message is sent to a non-socket port (such as TIPC's configuration service or network topology service).

2012-04-19tipc: Ensure network address change doesn't impact new portAllan Stephens1-4/+11
Re-orders port creation logic so that the initialization of a new port's message header template occurs while the port list lock is held. This ensures that a change to the node's network address that occurs at the same time as the port is being created does not result in the template identifying the sender using the former network address. The new approach guarantees that the new port's template is using the current network address or that it will be updated when the address changes.

2012-04-19tipc: Optimize re-initialization of port message header templatesAllan Stephens1-2/+0
Removes an unnecessary check in the logic that updates the message header template for existing ports when a node's network address is first assigned. There is no longer any need to check to see if the node's network address has actually changed since the calling routine has already verified that this is so.

2012-04-19tipc: Ensure network address change doesn't impact name table updatesAllan Stephens1-4/+4
Revises routines that add and remove an entry from a node's name table so that the publication scope lists are updated properly even if the node's network address is changed in mid-operation.

2012-04-19tipc: Add routines for safe checking of node's network addressAllan Stephens4-6/+24
Introduces routines that test whether a given network address is equal to a node's own network address or if it lies within the node's own network cluster, and which work properly regardless of whether the node is using the default network address <0.0.0> or a non-zero network address that is assigned later on. In essence, these routines ensure that address <0.0.0> is treated as an alias for "this node", regardless of which network address the node is actually using. Old users of the pre-existing more strict match in_own_cluster() have been accordingly redirected to what is now called in_own_cluster_exact() --- which does not extend matching to <0,0,0>.

2012-04-19tipc: Don't record failed publication attempt as a successAllan Stephens1-2/+3

2012-04-19tipc: Update node-scope publications when network address is assignedAllan Stephens2-7/+12
Ensures that node-scope name publications that exist prior to the configuration of a node's network address are properly re-initialized with that address when it is assigned. TIPC's node-scope publications are now tracked using a publications list like the lists used for cluster-scope and zone-scope publications so they can be easily updated when required. The inclusion of node scope name publications in a conventional publication list means that they must now also be withdrawn, just like cluster and zone scope publications are currently withdrawn. So some conditional tests on scope ==/!= TIPC_NODE_SCOPE are inserted/removed accordingly.

2012-04-19tipc: Separate cluster-scope and zone-scope names into distinct listsAllan Stephens1-5/+26
Utilizes distinct lists to track zone-scope and cluster-scope names published by a node. For now, TIPC continues to process the entries in both lists in the same way; however, an upcoming patch will utilize the existence of the lists to prevent the sending of cluster-scope names to nodes that are not part of the local cluster. To achieve this, an array of publication lists is introduced, so that they can be iterated over and accessed via publ->scope as an index where convenient.

2012-04-19powerpc/85xx: don't call of_platform_bus_probe() twiceTimur Tabi3-22/+8
Commit 46d026ac ("powerpc/85xx: consolidate of_platform_bus_probe calls") replaced platform-specific of_device_id tables with a single function that probes the most of the busses in 85xx device trees. If a specific platform needed additional busses probed, then it could call of_platform_bus_probe() again. Typically, the additional platform-specific busses are children of existing busses that have already been probed. of_platform_bus_probe() does not handle those child busses automatically. Unfortunately, this doesn't actually work. The second (platform-specific) call to of_platform_bus_probe() never finds any of the busses it's asked to find. To remedy this, the platform-specific of_device_id tables are eliminated, and their entries are merged into mpc85xx_common_ids[], so that all busses are probed at once.

2012-04-19net ax25: Reorder ax25_exit to remove races.Eric W. Biederman1-4/+5
While reviewing the sysctl code in ax25 I spotted races in ax25_exit where it is possible to receive notifications and packets after already freeing up some of the data structures needed to process those notifications and updates. Call unregister_netdevice_notifier early so that the rest of the cleanup code does not need to deal with network devices. This takes advantage of my recent enhancement to unregister_netdevice_notifier to send unregister notifications of all network devices that are current registered. Move the unregistration for packet types, socket types and protocol types before we cleanup any of the ax25 data structures to remove the possibilities of other races. Signed-off-by: Eric W.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI", switchable using a password protected AT command. Both product ID and USB interface configuration will change when switched. The "sierra_net" driver supports the "Direct IP" mode. This driver supports the "QMI" mode. There are also multiple possible USB interface configurations in each mode, some providing more than one wwan interface. Like many other devices made for Windows, different interface types are identified using a static interface number. We define a Sierra specific interface whitelist to support this.

Also shift initial value of its last_arp_tx so that it doesn't immediately cause fake detection of "up" state.

The sp_pri_to_cos[] array size depends on the config but lets say it is BX_E3B0_MAX_NUM_COS_PORT0 and max_num_of_cos is also DCBX_E3B0_MAX_NUM_COS_PORT0. In the original code "pri == max_num_of_cos" was accepted but it is one past the end of the array. Also we used "pri" before capping it.

2012-04-19ksz884x: don't copy too much in netdev_set_mac_address()Dan Carpenter1-1/+1
MAX_ADDR_LEN is 32. ETH_ALEN is 6. mac->sa_data is a 14 byte array, so the memcpy() is doing a read past the end of the array. I asked about this on netdev and Ben Hutchings told me it's supposed to be copying ETH_ALEN bytes (thanks Ben). Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

2012-04-19xen/xenbus: Add quirk to deal with misconfigured backends.Konrad Rzeszutek Wilk1-16/+53
A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" CC: stable@kernel.org Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> [v3: Split delay in non-essential (30 seconds) and essential devices per Ian and Stefano suggestion] [v4: Added comments per Stefano suggestion] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
