commit 721d92fc6373dee15846216f9d178ec240ec0fd7 upstream. This adds the N8 to the list of devices in cdc-acm, in order to get the secondary ACM device exposed.

2010-09-20USB: cdc-acm: Fixing crash when ACM probing interfaces with no endpoint ↵Toby Gray
descriptors. commit 577045c0a76e34294f902a7d5d60e90b04d094d0 upstream. Certain USB devices, such as the Nokia X6 mobile phone, don't expose any endpoint descriptors on some of their interfaces. If the ACM driver is forced to probe all interfaces on a device the a NULL pointer dereference will occur when the ACM driver attempts to use the endpoint of the alternative settings. One way to get the ACM driver to probe all the interfaces is by using the /sys/bus/usb/drivers/cdc_acm/new_id interface. This patch checks that the endpoint pointer for the current alternate settings is non-NULL before using it.

2010-09-20USB: cdc-acm: Adding second ACM channel support for various Nokia and one ↵Toby Gray
Samsung phones commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream. S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem with a standard AT-command interface, which is picked up correctly by CDC-ACM. The second ACM port is marked as having a vendor-specific protocol. This means that the ACM driver will not claim the second channel by default. This adds support for the second ACM channel for the following devices: Nokia E63 Nokia E75 Nokia 6760 Slide Nokia E52 Nokia E55 Nokia E72 Nokia X6 Nokia N97 Mini Nokia 5800 Xpressmusic Nokia E90 Samsung GTi8510 (INNOV8) Signed-off-by: Toby Gray <toby.gray@realvnc.com> Cc: Oliver Neukum <oliver@neukum.name> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-09-20USB: Exposing second ACM channel as tty for Nokia S60 phones.Adrian Taylor
commit c1479a92cf0a7792298d364e44a781550621cb58 upstream. Nokia S60 phones expose two ACM channels. The first is a modem and is picked up by the standard AT-command interface information in the CDC-ACM driver. The second is marked as having a vendor-specific protocol. Normally, we don't expose those as ttys. (On some other devices, they may be claimed by the rndis_host driver and used as a network interface). But on S60 this second ACM channel is the way that third-party S60 application developers are expected to communicate over USB. It acts as a serial device at the S60 end, and so it should on Linux too. The list of devices is largely derived from: http://wiki.forum.nokia.com/index.php/S60_Platform_and_device_identification_codes http://wiki.forum.nokia.com/index.php/Nokia_USB_Product_IDs and includes only the S60 3rd Edition+ devices documented there. There are many devices for which the USB device ID is not documented, including: Nokia 6290 Nokia E63 Nokia 5630 XpressMusic Nokia 5730 XpressMusic Nokia 6710 Navigator Nokia 6720 classic Nokia 6730 Classic Nokia 6760 slide Nokia 6790 slide Nokia 6790 Surge Nokia E52 Nokia E55 Nokia E71x (AT&T) Nokia E72 Nokia E75 Nokia E75 US+LTA variant Nokia N79 Nokia N86 8MP Nokia 5230 (RM-588) Nokia 5230 (RM-594) Nokia 5530 XpressMusic Nokia 5530 XpressMusic (china) Nokia 5800 XM Nokia N97 (RM-506) Nokia N97 mini Nokia X6 It would be good to add those subsequently.

2010-07-05USB: cdc-acm: fix resource reclaim in error path of acm_probeAxel Lin
commit c2572b78aa0447244a38e555ebb1b3b48a0088a5 upstream. This patch fixes resource reclaim in error path of acm_probe: 1. In the case of "out of memory (read urbs usb_alloc_urb)\n")", there is no need to call acm_read_buffers_free(acm) here. Fix it by goto alloc_fail6 instead of alloc_fail7. 2. In the case of "out of memory (write urbs usb_alloc_urb)", usb_alloc_urb may fail in any iteration of the for loop. Current implementation does not properly free allocated snd->urb. Fix it by goto alloc_fail8 instead of alloc_fail7. 3. In the case of device_create_file(&intf->dev,&dev_attr_iCountryCodeRelDate) fail, acm->country_codes is kfreed. As a result, device_remove_file for dev_attr_wCountryCodes will not be executed in acm_disconnect. Fix it by calling device_remove_file for dev_attr_wCountryCodes before goto skip_countries.

commit ec412b92dbe3ea839716853eea058d1bcc5e6ca4 upstream. usb_bulk_msg() transfers only bytes up to the maximum packet size. It must be repeated by the usbtmc driver until all bytes of a TMC message are transfered. Without this patch, ETIMEDOUT is reported when writing TMC messages larger than the maximum USB bulk size and the transfer remains incomplete. The user will notice that the device hangs and must be reset by either closing the application or pulling the plug.

Hence reconnecting the device results in creation of /dev/ttyACM(x+1). The same happens when the system is hibernated during a PPP connection. This memory leak is due to the fact that when the tty is hung up, tty_port_close_start() returns always zero, and acm_tty_close() never reaches the point where acm_tty_unregister() is called.

2009-09-23USB: usbtmc: sanity checks for DEV_DEP_MSG_IN urbsGuus Sliepen
According to the specifications, an instrument should not return more data in a DEV_DEP_MSG_IN urb than requested. However, some instruments can send more than requested. This could cause the kernel to write the extra data past the end of the buffer provided by read(). Fix this by checking that the value of the TranserSize field is not larger than the urb itself and not larger than the size of the userspace buffer. Also correctly decrement the remaining size of the buffer when userspace read()s more than USBTMC_SIZE_IOBUFFER.

2009-04-14cdc-acm: Fix long standing abuse of tty->low_latencyAlan Cox
ACM sets the low latency flag but calls the flip buffer routines from IRQ context which isn't permitted (and as of 2.6.29 causes a warning hence this one was caught) Fortunatelt ACM doesn't need to set this flag in the first place as it only set it to work around problems in ancient (pre tty flip rewrite) kernels.
