* cfg80211: change GO_CONCURRENT to IR_CONCURRENT for STAArik Nemtsov2015-05-061-1/+1
| | | | | | | | | | | | | The GO_CONCURRENT regulatory definition can be extended to station interfaces requesting to IR as part of TDLS off-channel operations. Rename the GO_CONCURRENT flag to IR_CONCURRENT and allow the added use-case. Change internal users of GO_CONCURRENT to use the new definition.

| | | | | | | | | | | This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, iflink of the parent interface was always accessed, even when interface didn't have a parent and hence we crashed there. Handle the interface types properly: for a child interface, return the ifindex of the parent, for parent interface, return its ifindex. For child devices, make sure to set the parent pointer prior to invoking register_netdevice(), this allows the new ndo to be called by the stack immediately after the child device is registered.

| * net: remove unused 'dev' argument from netif_needs_gso()Johannes Berg2015-04-172-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 04ffcb255f22 ("net: Add ndo_gso_check") Tom originally added the 'dev' argument to be able to call ndo_gso_check(). Then later, when generalizing this in commit 5f35227ea34b ("net: Generalize ndo_gso_check to ndo_features_check") Jesse removed the call to ndo_gso_check() in netif_needs_gso() by calling the new ndo_features_check() in a different place. This made the 'dev' argument unused. Remove the unused argument and go back to the code as before.

| * act_mirred: Fix bogus header when redirecting from VLANHerbert Xu2015-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you redirect a VLAN device to any device, you end up with crap in af_packet on the xmit path because hard_header_len is not equal to skb->mac_len. So the redirected packet contains four extra bytes at the start which then gets interpreted as part of the MAC address. This patch fixes this by only pushing skb->mac_len. We also need to fix ifb because it tries to undo the pushing done by act_mirred.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_filter_wr is requesting __GFP_NOFAIL allocation although it can return ENOMEM without any problems obviously (t4_l2t_set_switching does that already). So the non-failing requirement is too strong without any obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the failure paths easier. The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL and then checks the return value and returns -ENOMEM on failure. This doesn't make any sense what so ever. Either the allocation cannot fail or it can. del_filter_wr seems to be safe as well because the filter entry is not marked as pending and the return value is propagated up the stack up to c4iw_destroy_listen.

Mitch provides a fix for i40e, where VFs were gone and the associated VSI's had been removed and the rings were not stopped, which in some circumstances cased memory corruption or DMAR errors. So stop all the rings associated with each VF before releasing its resources. Also cleaned up a poorly indented piece of code. Fixes VF link state, where VF devices were assuming link is up unless told otherwise, which means that VFs instantiated on a PF with no link, would report the wrong state. Anjali adds support to add Flow director Sideband rules for a VF from it's PF. Fixes a recently discovered hardware issue, where after a VFLR hardware might be indicating to us a reset completion little too early, so wait another 10 msec for cache to be cleaned up. Jesse enables the user to dump the internal hardware state for better debugging by allowing a bash script to acquire information about the internal hardware state. The data output to the kernel log is collected by the script and can then be sent to Intel. Also fixed a possible failure path to allocate memory that was found by smatch.

| | * i40e: Add support to program FDir SB rules for VF from PF through ethtoolAnjali Singhai Jain2015-04-141-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch we can now add Flow director Sideband rules for a VF from it's PF. Here is an example on how it can be done when VF id = 5 and queue = 2: "ethtool -N ethx flow-type udp4 src-ip x.x.x.x dst-ip y.y.y.y src-port p1 dst-port p2 action 2 user-def 5" User-def specifies VF id and action specifies queue.

| | * i40e: stop VF ringsMitch Williams2015-04-141-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly stop the rings belonging to each VF when disabling SR-IOV. Even though the VFs were gone, and the associated VSIs were removed, the rings were not stopped, and in some circumstances the hardware would continue to access the memory formerly used by the rings, causing memory corruption or DMAR errors, both of which would lead to general malaise of the kernel. To relieve this condition, explicitly stop all the rings associated with each VF before releasing its resources.

| * | bnx2x: Fix busy_poll vs netpollEric Dumazet2015-04-152-90/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9a2620c877454 ("bnx2x: prevent WARN during driver unload") switched the napi/busy_lock locking mechanism from spin_lock() into spin_lock_bh(), breaking inter-operability with netconsole, as netpoll disables interrupts prior to calling our napi mechanism. This switches the driver into using atomic assignments instead of the spinlock mechanisms previously employed. Based on initial patch from Yuval Mintz & Ariel Elior I basically added softirq starvation avoidance, and mixture of atomic operations, plain writes and barriers. Note this slightly reduces the overhead for this driver when no busy_poll sockets are in use.

| * | net: hip04: Make tx coalesce timer actually workThomas Gleixner2015-04-151-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code sets the expiry value of the timer to a relative value and starts it with hrtimer_start_expires. That's fine, but that only works once. The timer is started in relative mode, so the expiry value gets overwritten with the absolut expiry time (now + expiry). So once the timer expired, a new call to hrtimer_start_expires results in an immidiately expired timer, because the expiry value is already in the past. Use the proper mechanisms to (re)start the timer in the intended way. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: "David S.

Most noteworthy: - Add more Octeon-optimized crypto functions - Octeon crypto preemption and locking fixes - Little endian support for Octeon - Use correct CSR to soft reset Octeons - Support LEDs on the Octeon-based DSR-1000N - Fix PCI interrupt mapping for the Octeon-based DSR-1000N - Mark prom_free_prom_memory() as __init for a number of systems - Support for Imagination's Pistachio SOC. This includes arch and CLK bits. I'd like to merge pinctrl bits later - Improve parallelism of csum_partial for certain pipelines - Organize DTB files in subdirs like other architectures - Implement read_sched_clock for all MIPS platforms other than Octeon - Massive series of 38 fixes and cleanups for the FPU emulator / kernel - Further FPU remulator work to support new features. This sits on a separate branch which also has been pulled into the 4.1 KVM branch - Clean up and fixes for the SEAD3 eval board; remove unused file - Various updates for Netlogic platforms - A number of small updates for Loongson 3 platforms - Increase the memory limit for ATH79 platforms to 256MB - A fair number of fixes and updates for BCM47xx platforms - Finish the implementation of XPA support - MIPS FDC support.
