| * | USB: cdc-wdm: Avoid hanging on interface with no USB_CDC_DMM_TYPEBjørn Mork2012-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The probe does not strictly require the USB_CDC_DMM_TYPE descriptor, which is a good thing as it makes the driver usable on non-conforming interfaces. A user could e.g. bind to it to a CDC ECM interface by using the new_id and bind sysfs files. But this would fail with a 0 buffer length due to the missing descriptor. Fix by defining a reasonable fallback size: The minimum device receive buffer size required by the CDC WMC standard, revision 1.1 Signed-off-by: Bjørn Mork <bjorn@mork.no> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The CP2101/2/3 will respond to both a GET/SET_BAUDDIV command, and GET/SET_BAUDRATE command, while CP2104 and higher devices only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in kernel version 3.2.0 only implements the GET/SET_BAUDDIV command. This patch implements the two new codes for the GET/SET_BAUDRATE commands. Then there is a change in the way that the baudrate is assigned or retrieved. This is done according to the CP210x USB specification in AN571. This document can be found here: http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart Sections 5.3/5.4 describe the USB packets for the old baudrate method. Sections 5.5/5.6 describe the USB packets for the new method. This patch also implements the new request scheme, and eliminates the unnecessary baudrate calculations since it uses the "actual baudrate" method. This patch solves the problem reported for the CP2104 in bug 42586, and also keeps support for all other devices (CP2101/2/3). This patchfile is also attached to the bug report on bugzilla.kernel.org. This patch has been developed and test on the 3.2.0 mainline kernel version under Ubuntu 10.11.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xHCI hub port code gets passed a zero-based port number by the USB core. It then adds one to in order to find a device slot by port number and device speed by calling xhci_find_slot_id_by_port. That function clearly states it requires a one-based port number. The xHCI port status change event handler was using a zero-based port number that it got from find_faked_portnum_from_hw_portnum, not a one-based port number. This lead to the doorbells never being rung for a device after a resume, or worse, a different device with the same speed having its doorbell rung (which could lead to bad power management in the xHCI host controller). This patch should be backported to kernels as old as 2.6.39. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Acked-by: Andiry Xu <andiry.xu@amd.com> Cc: stable@vger.kernel.org

From Stefan Gula. 2) Resegmentation of TSO frames while trimming can violate invariants expected by callers, namely that the number of segments can only stay the same or decrease, never increase. If MSS changes, however, we can trim data but then end up with more segments. Fix this by only segmenting to the MSS already recorded in the SKB. That's the simplest fix for now and if we want to get more fancy in the future that's a more involved change. This probably explains some retransmit counter inaccuracies.

This happens with the spinlock held. However, there's a bug resetting this variable -- that happens after the spinlock has been released. This means that it is possible for interrupts to be missed if the reset happens after some other interrupt reasons were already added to the variable. I found this by code inspection, looking for a reason that we sometimes see random commands time out. It seems possible that this causes such behaviour, but I can't say for sure right now since it happens extremely infrequently on my test systems.

If a device is set online we only know that we already know the LCU. But if the pathgroup was lost in between we have to do a validate server again to activate some features. Since we have no indication when a pathgroup gets lost we have to do a validate server every time a device is set online.

* | | | | | vmwgfx: Fix assignment in vmw_framebuffer_create_handleRyan Mallon2012-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

Where is that paper bag ... ah here. I've failed to take an odd interaction between my other cleanups and this reclaim_buffers patch into account and also failed to properly test it. Looks like there are more dragons and hidden trapdoors in the drm release path than actual lines of code. Until I get a clue, let's just revert this.

Structures must not be passed to device_add() or device_register() more than once. Although these restrictions have applied ever since the driver model was first created, they have not been mentioned anywhere.
