Pull rdma fixes from Doug Ledford: "One ocrdma fix: - The new CQ API support was added to ocrdma, but they got the arming logic wrong, so without this, transfers eventually fail when they fail to arm the interrupt properly under load Two related fixes for mlx4: - When we added the 64bit extended counters support to the core IB code, they forgot to update the RoCE side of the mlx4 driver (the IB side they properly updated). I debated whether or not to include these patches as they could be considered feature enablement patches, but the existing code will blindy copy the 32bit counters, whether any counters were requested at all (a bug). These two patches make it (a) check to see that counters were requested and (b) copy the right counters (the 64bit support is new, the 32bit is not).

The dm9000 driver doesn't work in at least one device-tree configuration, spitting an error message on irq resource : [ 1.062495] dm9000 8000000.ethernet: insufficient resources [ 1.068439] dm9000 8000000.ethernet: not found (-2). [ 1.073451] dm9000: probe of 8000000.ethernet failed with error -2 The reason behind is that the interrupt might be provided by a gpio controller, not probed when dm9000 is probed, and needing the probe deferral mechanism to apply. Currently, the interrupt is directly taken from resources. This patch changes this to use the more generic platform_get_irq(), which handles the deferral. Moreover, since commit Fixes: 7085a740 ("drivers: platform: parse IRQ flags from resources"), the interrupt trigger flags are honored in platform_get_irq(), so remove the needless code in dm9000.

Latest version of the document is at http://www.ti.com/lit/ug/sprugr9h/sprugr9h.pdf and section 3.1 Host Packet Descriptor describes this field. Define and use a constant for the size of sw_data field similar to other fields in the struct for desc and document the sw_data field in the header. As the sw_data is not touched by hw, it's type can be changed to u32. Rename the helpers to match with the updated dma desc field sw_data.

The commit 89907779 ("netcp: try to reduce type confusion in descriptors") introduces a regression in Kernel 4.5-rc1 and it breaks get/set_pad_info() functionality. The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to store DMA/MEM buffer pointer and buffer size respectively. And in both cases for Keystone 2 the pointer type size is 32 bit regardless of LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally is not expected to be defined. Unfortunately, above commit changed buffer's pointers save/restore code (get/set_pad_info()) and added intermediate conversation to u64 which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver crash in RX/TX path due to "Unable to handle kernel NULL pointer" exception. This issue was reported and discussed in [1]. Hence, fix it by partially reverting above commit and restoring get/set_pad_info() functionality as it was before.

Dmitry Vyukov noted recently that the sctp_port_hashtable had an error in its size computation, observing that the current method never guaranteed that the hashsize (measured in number of entries) would be a power of two, which the input hash function for that table requires. The root cause of the problem is that two values need to be computed (one, the allocation order of the storage requries, as passed to __get_free_pages, and two the number of entries for the hash table). Both need to be ^2, but for different reasons, and the existing code is simply computing one order value, and using it as the basis for both, which is wrong (i.e. it assumes that ((1<<order)*PAGE_SIZE)/sizeof(bucket) is still ^2 when its not). To fix this, we change the logic slightly. We start by computing a goal allocation order (which is limited by the maximum size hash table we want to support. Then we attempt to allocate that size table, decreasing the order until a successful allocation is made. Then, with the resultant successful order we compute the number of buckets that hash table supports, which we then round down to the nearest power of two, giving us the number of entries the table actually supports. I've tested this locally here, using non-debug and spinlock-debug kernels, and the number of entries in the hashtable consistently work out to be powers of two in all cases.

This patch fixes the problem that more CAN messages could be sent to the interface as could be send on the CAN bus. This was more likely for slow baud rates. The sleeping _start_xmit was woken up in the _write_bulk_callback. Under heavy TX load this produced another bulk transfer without checking the free_slots variable and hence caused the overflow in the interface.

In __request_region, if a conflict with a BUSY and MUXED resource is detected, then the caller goes to sleep and waits for the resource to be released. A pointer on the conflicting resource is kept. At wake-up this pointer is used as a parent to retry to request the region. A first problem is that this pointer might well be invalid (if for example the conflicting resource have already been freed). Another problem is that the next call to __request_region() fails to detect a remaining conflict. The previously conflicting resource is passed as a parameter and __request_region() will look for a conflict among the children of this resource and not at the resource itself. It is likely to succeed anyway, even if there is still a conflict. Instead, the parent of the conflicting resource should be passed to __request_region(). As a fix, this patch doesn't update the parent resource pointer in the case we have to wait for a muxed region right after.

In commit 44d27137 ("Bluetooth: Compress the size of struct hci_ctrl") we squashed down the size of the structure by using a union with the assumption that all users would use the flag to determine whether we had a req_complete or a req_complete_skb. Unfortunately we had a case in hci_req_cmd_complete() where we weren't looking at the flag. This can result in a situation where we might be storing a hci_req_complete_skb_t in a hci_req_complete_t variable, or vice versa. During some testing I found at least one case where the function hci_req_sync_complete() was called improperly because the kernel thought that it didn't require an SKB. Looking through the stack in kgdb I found that it was called by hci_event_packet() and that hci_event_packet() had both of its locals "req_complete" and "req_complete_skb" pointing to the same place: both to hci_req_sync_complete(). Let's make sure we always check the flag. For more details on debugging done, see <http://crbug.com/588288>.

The PHY link state is not chaged in GENETv2 caused by the previous commit 49f7a471 ("net: bcmgenet: Properly configure PHY to ignore interrupt") was set to PHY_IGNORE_INTERRUPT in bcmgenet_mii_probe(). The internal PHY should use phy_mac_interrupt() when not in use PHY_POLL. The statement for phy_mac_interrupt() has two conditions. The first condition to check GENET_HAS_MDIO_INTR is not related PHY link state, so this patch removes it.

The unix_stream_read_generic function tries to use a continue statement to restart the receive loop after waiting for a message. This may not work as intended as the caller might use a recvmsg call to peek at control messages without specifying a message buffer. If this was the case, the continue will cause the function to return without an error and without the credential information if the function had to wait for a message while it had returned with the credentials otherwise. Change to using goto to restart the loop without checking the condition first in this case so that credentials are returned either way.

However, when ino is compared with sock_i_ino return value of type unsigned long, ino is sign extended to signed long, and this results to incorrect comparison on 64-bit architectures for inode numbers greater than INT_MAX.

If we fail to update the PHY, we should print a warning and continue. The current code to exit is buggy as it has not freed up the NIC resources yet. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Fix bnxt_update_phy_setting() to check the correct parameters when determining whether to update the PHY. Requested line speed/duplex should only be checked for forced speed mode. This avoids unnecessary link interruptions when loading the driver. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

When shutting down the NIC, we shutdown async event processing before freeing all the rings. If there is a link change event during reset, the driver may miss it and the link state may be incorrect after the NIC is re-opened. Poll the link at the end of __bnxt_open_nic() to get the correct link status. Signed-off-by Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
