2012-05-17staging: comedi: fix infoleak to userspaceVasiliy Kulikov
commit 819cbb120eaec7e014e5abd029260db1ca8c5735 upstream. driver_name and board_name are pointers to strings, not buffers of size COMEDI_NAMELEN. Copying COMEDI_NAMELEN bytes of a string containing less than COMEDI_NAMELEN-1 bytes would leak some unrelated bytes.

commit 15d93ed070125d51693f102a0f94045dcaf30d9b upstream. This patch adds some device ids. The list of supported devices was extracted from realteks driver package. (0x050d, 0x815F) and (0x0df6, 0x004b) are not in the official list of supported devices and may not work correctly. In case of problems with these, they should probably be removed from the list.

2012-03-14Staging: rtl8192su: Fix procfs code for interfaces not named wlan0Ben Hutchings
commit 41a38d9e632f7c9ec5ad8fc627567d97f4302c4a upstream. The current code creates directories in procfs named after interfaces, but doesn't handle renaming. This can result in name collisions and consequent WARNINGs. It also means that the interface name cannot reliably be used to remove the directory - in fact the current code doesn't even try, and always uses "wlan0"! Since the name of a proc_dir_entry is embedded in it, use that when removing it. Add a netdev notifier to catch interface renaming, and remove and re-add the directory at this point.

2012-03-14staging: hv: Fix GARP not sent after Quick MigrationHaiyang Zhang
commit c996edcf1c451b81740abbcca5257ed7e353fcc6 upstream. After Quick Migration, the network is not immediately operational in the current context when receiving RNDIS_STATUS_MEDIA_CONNECT event. So, I added another netif_notify_peers() into a scheduled work, otherwise GARP packet will not be sent after quick migration, and cause network disconnection.

2012-03-14staging: usbip: bugfix for isochronous packets and optimizationArjan Mels
commit 28276a28d8b3cd19f4449991faad4945fe557656 upstream. For isochronous packets the actual_length is the sum of the actual length of each of the packets, however between the packets might be padding, so it is not sufficient to just send the first actual_length bytes of the buffer. To fix this and simultanesouly optimize the bandwidth the content of the isochronous packets are send without the padding, the padding is restored on the receiving end.

2011-01-06staging: usbip: Process event flags without delayMax Vozeler
commit 584c5b7cf06194464240280483ee0376cdddbbae upstream. The way the event handler works can cause it to delay events until eventual wakeup for another event. For example, on device detach (vhci): - Write to sysfs detach file -> usbip_event_add(VDEV_EVENT_DOWN) -> wakeup() #define VDEV_EVENT_DOWN (USBIP_EH_SHUTDOWN | USBIP_EH_RESET). - Event thread wakes up and passes the event to event_handler() to process. - It processes and clears the USBIP_EH_SHUTDOWN flag then returns. - The outer event loop (event_handler_loop()) calls wait_event_interruptible(). The processing of the second flag which is part of VDEV_EVENT_DOWN (USBIP_EH_RESET) did not happen yet. It is delayed until the next event. This means the ->reset callback may not happen for a long time (if ever), leaving the usbip port in a weird state which prevents its reuse. This patch changes the handler to process all flags before waiting for another wakeup. I have verified this change to fix a problem which prevented reattach of a usbip device. It also helps for socket errors which missed the RESET as well. The delayed event processing also affects the stub side of usbip and the error handling there.

commit 0c9a32f0192e656daa2ff3c9149f6d71b4a1b873 upstream. This patch changes vhci to behave like dummy and other hcds when disconnecting a device.

2011-01-06Staging: vt6655: fix buffer overflowDan Carpenter
commit dd173abfead903c7df54e977535973f3312cd307 upstream. "param->u.wpa_associate.wpa_ie_len" comes from the user. We should check it so that the copy_from_user() doesn't overflow the buffer. Also further down in the function, we assume that if "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is initialized. To make that work, I changed the test here to say that if "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return -EINVAL. Oddly, we only use the first element of the abyWPAIE[] array. So I suspect there may be some other issues in this function.

commit 15dd1c9f53b31cdc84b8072a88c23fa09527c596 upstream. Increased storvsc ringbuffer and max_io_requests. This now more closely mimics the numbers on Hyper-V. And will allow more IO requests to take place for the SCSI driver. Max_IO is set to double from what it was before, Hyper-V allows it and we have had appliance builder requests to see if it was a problem to increase the number. Ringbuffer size for storvsc is now increased because I have seen A few buffer problems on extremely busy systems. They were Set pretty low before. And since max_io_requests is increased I Really needed to increase the buffer as well.

commit e5fa721d1c2a54261a37eb59686e18dee34b6af6 upstream. Fixed the value of the 64bit-hole inside ring buffer, this caused a problem on Hyper-V when running checked Windows builds. Checked builds of Windows are used internally and given to external system integrators at times. They are builds that for example that all elements in a structure follow the definition of that Structure. The bug this fixed was for a field that we did not fill in at all (Because we do Not use it on the Linux side), and the checked build of windows gives errors on it internally to the Windows logs. This fixes that error.

commit b681b5886bb5d1f5b6750a0ed7c62846da7ccea4 upstream. Fix missing functions for net_device_ops. It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27, the default functions for Ethernet, like eth_change_mtu(), were assigned by ether_setup(). But in 2.6.32, these function pointers moved to net_device_ops structure and no longer be assigned in ether_setup(). So we need to set these functions in our driver code. It will ensure the MTU won't be set beyond 1500. Otherwise, this can cause an error on the server side, because the HyperV linux driver doesn't support jumbo frame yet.

commit 060132ae42cce3f9d2fd34d9a17b98362b44b9f9 upstream. This patch prevents the code from calling parport_release and parport_unregister_device twice with the same arguments - and thus fixes an oops. Rationale: After the first call the parport is already released and the handle isn't valid anymore and calling parport_release and parport_unregister_device twice isn't a good idea.

2010-08-10comedi: Uncripple 8255-based DIO subdevicesIan Abbott
(Note: upstream comedi configuration has been overhauled, so this patch does not apply there.) Several comedi drivers call subdev_8255_init() (declared in "drivers/staging/comedi/drivers/8255.h") to set up one or more DIO subdevices. This should be provided by the 8255.ko module, but unless the CONFIG_COMEDI_8255 or CONFIG_COMEDI_8255_MODULE macro is defined, the 8255.h header uses a dummy inline version of the function instead. This means the comedi devices end up with an "unused" subdevice with 0 channels instead of a "DIO" subdevice with 24 channels! This patch provides a non-interactive COMEDI_8255 option and selects it whenever the COMEDI_PCI_DRIVERS or COMEDI_PCMCIA_DRIVERS options are selected.

commit ea4ceb18b525fd7016c10995c0f1313a729c7e2b upstream. When the seqno for a vis packet had a wrap around from i.e. 255 to 0, add_packet() would falsely claim the older packet with the seqno 255 as newer as the one with the seqno of 0 and would therefore ignore the new packet. This happens with all following vis packets until the old vis packet expires after 180 seconds timeout. This patch fixes this issue and gets rid of these highly undesired 3min. breaks for the vis-server.

commit 107c32fe68f0b64acb7edd31d44d79b87c7fa8b4 upstream. send_vis_packets() would disable interrupts before calling dev_queue_xmit() which resulting in a backtrace in local_bh_enable(). Fix this by using kref on the vis_info object so that we can call send_vis_packets() without holding vis_hash_lock. vis_hash_lock also used to protect recv_list, so we now need a new lock to protect that instead of vis_hash_lock.
