2016-04-21drivers: net: cpsw: fix wrong regs access in cpsw_ndo_openGrygorii Strashko
The cpsw_ndo_open() could try to access CPSW registers before calling pm_runtime_get_sync(). This will trigger L3 error: WARNING: CPU: 0 PID: 21 at drivers/bus/omap_l3_noc.c:147 l3_interrupt_handler+0x220/0x34c() 44000000.ocp:L3 Custom Error: MASTER M2 (64-bit) TARGET L4_FAST (Idle): Data Access in Supervisor mode during Functional access and CPSW will stop functioning. Hence, fix it by moving pm_runtime_get_sync() before the first access to CPSW registers in cpsw_ndo_open(). Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

2016-04-20fm10k: fix possible null pointer deref after kcallocJacob Keller
When writing a new default redirection table, we needed to populate a new RSS table using ethtool_rxfh_indir_default. We populated this table into a region of memory allocated using kcalloc, but never checked this for NULL. Fix this by moving the default table generation into fm10k_write_reta. If this function is passed a table, use it. Otherwise, generate the default table using ethtool_rxfh_indir_default, 4 at at time.

The diagram represents bit layout of the multi-bit VLAN update message format. Typically these diagrams are drawn using some power of 2 as the base, to more easily grasp where fields split. Although the numbers above can make it somewhat easy to understand which bit you're looking at, it makes the break points not line up.

2016-04-20fm10k: fix documentation of fm10k_tlv_parse_attrJacob Keller
fm10k_tlv_parse_attr is supposed to return FM10K_NOT_IMPLEMENTED for any TLV who's attribute id lies outside the range of results. It does not do this today. In addition, the documentation does not indicate that other attributes which are not implemented for a given TLV will be silently ignored. Fix this. Clean up the logic so that we don't rely on the fact that FM10K_NOT_IMPLEMENTED is greater than zero, as this can easily cause confusion. A future extension could look into some way of reporting unknown TLVs in order to make issues more easily discoverable. We can't just return FM10K_NOT_IMPLEMENTED here because we don't want to drop the entire message if it has an unknown TLV. While here, update the copyright year.

2016-04-20fm10k: do not disable PCI device in fm10k_io_error_detectedJacob Keller
fm10k_io_error_detected() does not need to call pci_disable_device(). In the cases where the reset needs to occur, the stack flow will result in calling fm10k_remove() which already disables the PCI device. If we leave the pci_disable_device(), we result in a warning about disabling an already disabled device. Many PCI drivers do call pci_disable_device() in their .error_detected() routines, but it does not appear to be required. In addition, these drivers have a check "is_pci_enabled()" call in their remove routines, which is how they chose to handle the duplicate device disable. This seems incorrect, since the PCI device structure is reference counted. It is very possible that the reference count for the PCI device could be greater than 1. In this case, you would remove the PCI device within the error_detected routine, reducing count to 1, then remove it again in the remove function, reducing it to zero. This would result in yet another disable somewhere else failing. Thus, we shouldn't be using is_pci_enabled() to check for this issue. Instead, just remove the extraneous pci_device_disable() found within the error_detected routine.

2016-04-20fm10k: correctly handle LPORT_MAP errorJacob Keller
Currently, any error responses from the switch manager after an LPORT_MAP request are silently ignored. At most the mailbox message will be reported as an error. This can result in unexpected behavior when the switch manager has configured a port with zero bandwidth. Add support for reading the fm10k_swapi_error structure from LPORT_MAP responses. If the message contains the necessary TLV and has a non-zero error code, report link down, clear the dglort_map, and delay the next get_host_state call by a reasonable delay. Also log an error message indicating that the LPORT_MAP request failed. The delay ensures preventing an interrupt storm on the switch manager, and reduces the number of mailbox messages we send in this scenario drastically.

2016-04-20fm10k: Fix multicast mode sync issuesNgai-Mint Kwan
Multicast mode checking is no longer a requirement to perform unicast and multicast address syncs. Specifically, a device operating in promiscuous and/or all multicast mode is not excluded. The issue occurs when the netdev is pre-configured to either multicast mode and is enabled for the first time. The multicast-group table in the Switch Manager will be missing obvious multicast entries associated to this netdev. Changes were also made to disallow unicast and multicast syncs with VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry. Requests with VLAN 0 by the netdev are only generated when the driver is freshly installed and the default VID is not set.

2016-04-16nfp: add async reconfiguration mechanismJakub Kicinski
Some callers of nfp_net_reconfig() are in atomic context so we used to busy wait for commands to complete. In worst case scenario that means locking up a core for up to 5 seconds when a command times out. Lets add a timer-based mechanism of asynchronously checking whether reconfiguration completed successfully for atomic callers to use. Non-atomic callers can now just sleep. The approach taken is quite simple because (1) synchronous reconfigurations always happen under RTNL (or before device is registered); (2) we can coalesce pending reconfigs. There is no need for request queues, timer which eventually takes a look at reconfiguration result to report errors is good enough.

2016-04-15qlge: Replace create_singlethread_workqueue with alloc_ordered_workqueueAmitoj Kaur Chawla
Replace deprecated create_singlethread_workqueue with alloc_ordered_workqueue. Work items include getting tx/rx frame sizes, resetting MPI processor, setting asic recovery bit so ordering seems necessary as only one work item should be in queue/executing at any given time, hence the use of alloc_ordered_workqueue. WQ_MEM_RECLAIM flag has been set since ethernet devices seem to sit in memory reclaim path, so to guarantee forward progress regardless of memory pressure.

2016-04-15cxgb4: Set VPD size so we can read both VPD structuresHariprasad Shenai
Chelsio adapters have two VPD structures stored in the VPD: - offset 0x000: an abbreviated VPD, and - offset 0x400: the complete VPD. After 104daa71b396 ("PCI: Determine actual VPD size on first access"), the PCI core computes the valid VPD size by parsing the VPD starting at offset 0x0. That size only includes the abbreviated VPD structure, so reads of the complete VPD at 0x400 fail. Explicitly set the VPD size with pci_set_vpd_size() so the driver can read both VPD structures. [bhelgaas: changelog, split patches, rename to pci_set_vpd_size() and return int (not ssize_t)] Fixes: 104daa71b396 ("PCI: Determine actual VPD size on first access") Tested-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Casey Leedom <leedom@chelsio.com> Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-04-14bgmac: fix MAC soft-reset bit for corerev > 4Felix Fietkau
Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means only some devices as most of BCM4708A0KF-s got core rev 4). This was tested for regressions on BCM47094 which doesn't seem to care which bit gets used.
