2016-12-05USB: OHCI: ohci-omap: remove useless functionsManjunath Goudar1-25/+11
The ohci_hcd_omap_drv_probe and ohci_hcd_omap_drv_remove functions are removed as these are useless functions except calling usb_hcd_omap_probe and usb_hcd_omap_remove functions. The usb_hcd_omap_probe function renamed to ohci_hcd_omap_probe and usb_hcd_omap_remove function renamed to ohci_hcd_omap_remove for proper naming.

2016-12-05fsl/usb: Workarourd for USB erratum-A005697Changming Huang5-0/+28
The EHCI specification states the following in the SUSP bit description: In the Suspend state, the port is sensitive to resume detection. Note that the bit status does not change until the port is suspended and that there may be a delay in suspending a port if there is a transaction currently in progress on the USB. However, in NXP USBDR controller, the PORTSCx[SUSP] bit changes immediately when the application sets it and not when the port is actually suspended. So the application must wait for at least 10 milliseconds after a port indicates that it is suspended, to make sure this port has entered suspended state before initiating this port resume using the Force Port Resume bit. This bit is for NXP controller, not EHCI compatible.

2016-12-05usb: hub: Wait for connection to be reestablished after port resetGuenter Roeck1-2/+9
On a system with a defective USB device connected to an USB hub, an endless sequence of port connect events was observed. The sequence of events as observed is as follows: - Port reports connected event (port status=USB_PORT_STAT_CONNECTION). - Event handler debounces port and resets it by calling hub_port_reset(). - hub_port_reset() calls hub_port_wait_reset() to wait for the reset to complete. - The reset completes, but USB_PORT_STAT_CONNECTION is not immediately set in the port status register. - hub_port_wait_reset() returns -ENOTCONN. - Port initialization sequence is aborted. - A few milliseconds later, the port again reports a connected event, and the sequence repeats. This continues either forever or, randomly, stops if the connection is already re-established when the port status is read. It results in a high rate of udev events. This in turn destabilizes userspace since the above sequence holds the device mutex pretty much continuously and prevents userspace from actually reading the device status. To prevent the problem from happening, let's wait for the connection to be re-established after a port reset. If the device was actually disconnected, the code will still return an error, but it will do so only after the long reset timeout.

2016-12-05usbip: vudc: Refactor init_vudc_hw() to be more obviousKrzysztof Opasiak1-17/+18
Current implementation of init_vudc_hw() adds ep0 to ep_list and then after looping through all endpoints removes it from that list. As this may be misleading let's refactor this function and avoid adding and removing ep0 to eplist and place it immediately in correct place. In addition let's remove redundant 0 assignments as ep array is zeroed during allocation.

2016-11-29usb: fix improper return value when kzalloc failsPan Bian1-0/+1
The comment says function wa_nep_queue() should return 0 if ok, and <0 errno code on error. However, its implementation always returns 0, even if the call to kzalloc() fails. As a result, the return value may be inconsistent with the execution status, which may mislead the callers. This patch fixes the bug, returning -ENOMEM when the call to kzalloc() fails.

2016-11-29usb: return correct errno on failuresPan Bian1-0/+1
In function __wa_xfer_setup_segs(), variable result takes the return value. Its value should be a negative errno on failures. Because result may be reassigned in a loop, and its value is guaranteed to be not less than 0 during the following repeats of the loop. So when the call to kmalloc() or usb_alloc_urb() fails in the loop, the value of variable result may be 0 (indicates no error), which is inconsistent with the execution status. This patch fixes the bug, initializing variable result with -ENOMEM in the loop. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-11-29usb: return correct errno code when krealloc failsPan Bian1-0/+1
In function wusb_dev_sec_add(), variable result takes the return value. Its value should be negative on failures. When function krealloc() is called, an earlier check of variable result guarantees that the value of result must not be less than "sizeof(*secd)", and result is not reassigned when krealloc() returns a NULL pointer. As a result, a positive value may be returned, which makes it impossible for the caller of wusb_dev_sec_add() to detect the error. This patch fixes the bug by assigning -ENOMEM to result when krealloc() returns NULL. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Using a regulator to handle VBUS will eliminate the need for platform data and callbacks, and make the driver more generic allowing different types of regulators to handle VBUS. The regulator equivalents to the platform callbacks are: set_power -> regulator_enable/regulator_disable get_power -> regulator_is_enabled get_oci -> regulator_get_error_flags ocic_notify -> regulator event notification Signed-off-by: Axel Haslam <ahaslam@baylibre.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

In preparation to use a regulator instead of callbacks, move the platform data callbacks into separate functions.

2016-11-26tipc: resolve connection flow control compatibility problemJon Paul Maloy1-1/+1
In commit 10724cc7bb78 ("tipc: redesign connection-level flow control") we replaced the previous message based flow control with one based on 1k blocks. In order to ensure backwards compatibility the mechanism falls back to using message as base unit when it senses that the peer doesn't support the new algorithm. The default flow control window, i.e., how many units can be sent before the sender blocks and waits for an acknowledge (aka advertisement) is 512. This was tested against the previous version, which uses an acknowledge frequency of on ack per 256 received message, and found to work fine. However, we missed the fact that versions older than Linux 3.15 use an acknowledge frequency of 512, which is exactly the limit where a 4.6+ sender will stop and wait for acknowledge. This would also work fine if it weren't for the fact that if the first sent message on a 4.6+ server side is an empty SYNACK, this one is also is counted as a sent message, while it is not counted as a received message on a legacy 3.15-receiver. This leads to the sender always being one step ahead of the receiver, a scenario causing the sender to block after 512 sent messages, while the receiver only has registered 511 read messages. Hence, the legacy receiver is not trigged to send an acknowledge, with a permanently blocked sender as result. We solve this deadlock by simply allowing the sender to send one more message before it blocks, i.e., by a making minimal change to the condition used for determining connection congestion.

We set "tgec->cfg" to NULL before passing it to kfree(). There is no need to set it to NULL at all. Let's just delete it. Fixes: 57ba4c9b56d8 ("fsl/fman: Add FMan MAC support") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-11-26tipc: improve sanity check for received domain recordsJon Paul Maloy1-5/+5
In commit 35c55c9877f8 ("tipc: add neighbor monitoring framework") we added a data area to the link monitor STATE messages under the assumption that previous versions did not use any such data area. For versions older than Linux 4.3 this assumption is not correct. In those version, all STATE messages sent out from a node inadvertently contain a 16 byte data area containing a string; -a leftover from previous RESET messages which were using this during the setup phase. This string serves no purpose in STATE messages, and should no be there. Unfortunately, this data area is delivered to the link monitor framework, where a sanity check catches that it is not a correct domain record, and drops it. It also issues a rate limited warning about the event. Since such events occur much more frequently than anticipated, we now choose to remove the warning in order to not fill the kernel log with useless contents. We also make the sanity check stricter, to further reduce the risk that such data is inavertently admitted. Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> Signed-off-by: David S.

2016-11-26tipc: fix compatibility bug in link monitoringJon Paul Maloy1-2/+3
commit 817298102b0b ("tipc: fix link priority propagation") introduced a compatibility problem between TIPC versions newer than Linux 4.6 and those older than Linux 4.4. In versions later than 4.4, link STATE messages only contain a non-zero link priority value when the sender wants the receiver to change its priority. This has the effect that the receiver resets itself in order to apply the new priority. This works well, and is consistent with the said commit. However, in versions older than 4.4 a valid link priority is present in all sent link STATE messages, leading to cyclic link establishment and reset on the 4.6+ node. We fix this by adding a test that the received value should not only be valid, but also differ from the current value in order to cause the receiving link endpoint to reset.

2016-11-26net: ethernet: mvneta: Remove IFF_UNICAST_FLT which is not implementedAndrew Lunn1-1/+1
The mvneta driver advertises it supports IFF_UNICAST_FLT. However, it actually does not. The hardware probably does support it, but there is no code to configure the filter. As a quick and simple fix, remove the flag. This will cause the core to fall back to promiscuous mode.

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc fixes from Helge Deller: "On parisc we were still seeing occasional random segmentation faults and memory corruption on SMP machines. Dave Anglin then looked again at the TLB related code and found two issues in the PCI DMA and generic TLB flush functions. Then, in our startup code we had some timing of the cache and TLB functions to calculate a threshold when to use a complete TLB/cache flush or just to flush a specific range. This code produced a race with newly started CPUs and thus lead to occasional kernel crashes (due to stale TLB/cache entries). The patch by Dave fixes this issue by flushing the local caches before starting secondary CPUs and by removing the race. The last problem fixed by this series is that we quite often suffered from hung tasks and self-detected stalls on the CPUs. It was somehow clear that this was related to the (in v4.7) newly introduced cr16 clocksource and the own implementation of sched_clock(). I replaced the open-coded sched_clock() function and switched to the generic sched_clock() implementation which seems to have fixed this isse as well. All patches have been sucessfully tested on a variety of machines, including our debian buildd servers. All patches (beside the small pr_cont fix) are tagged for stable releases" * 'parisc-4.9-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Also flush data TLB in flush_icache_page_asm parisc: Fix race in pci-dma.c parisc: Switch to generic sched_clock implementation parisc: Fix races in parisc_setup_cache_timing() parisc: Fix printk continuations in system detection
