2012-02-03USB: usbsevseg: fix max lengthHarrison Metzger
commit 1097ccebe630170080c41df0edcf88e0626e9c75 upstream. This changes the max length for the usb seven segment delcom device to 8 from 6. Delcom has both 6 and 8 variants and having 8 works fine with devices which are only 6.

2012-01-12USB: isight: fix kernel bug when loading firmwareGreg Kroah-Hartman
commit 59bf5cf94f0fa3b08fb1258b52649077b7d0914d upstream. We were sending data on the stack when uploading firmware, which causes some machines fits, and is not allowed. Fix this by using the buffer we already had around for this very purpose. Reported-by: Wouter M. Koolen <wmkoolen@cwi.nl> Tested-by: Wouter M.

2011-03-07usb: iowarrior: don't trust report_size for buffer sizeKees Cook
commit 3ed780117dbe5acb64280d218f0347f238dafed0 upstream. If the iowarrior devices in this case statement support more than 8 bytes per report, it is possible to write past the end of a kernel heap allocation. This will probably never be possible, but change the allocation to be more defensive anyway.

commit 37e9066b2f85480d99d3795373f5ef0b00ac1189 upstream. brightness status is reported by the Apple Cinema Displays as an 'unsigned char' (u8) value, but the code used 'char' instead. Note that he driver was developed on the PowerPC architecture, where the two types are synonymous, which is not always the case. Fixed that. Otherwise the driver will interpret brightness levels > 127 as negative, and fail to load. Signed-off-by: pancho horrillo <pancho@pancho.name> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-01-06USB: emi62: fix crash when trying to load EMI 6|2 firmwareClemens Ladisch
commit ac06c06770bb8761b1f1f9bdf2f5420fa6d3e9fa upstream. While converting emi62 to use request_firmware(), the driver was also changed to use the ihex helper functions. However, this broke the loading of the FPGA firmware because the code tries to access the addr field of the EOF record which works with a plain array that has an empty last record but not with the ihex helper functions where the end of the data is signaled with a NULL record pointer, resulting in: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62] This can be fixed by changing the loop condition to test the return value of ihex_next_binrec() directly (like in emi26.c).

2009-09-23USB: sisusbvga: drop usb_buffer_allocPete Zaitcev
This patch falls out of my work to fix usbmon so it uses virtual addresses. It is not necessary, the "new" usbmon should work just fine with sisusbvga. However, it seems ridiculous that anyone would use uncached memory to transfer bulk data. Dropping the unnecessary use of usb_buffer_alloc should be beneficial here, in case anyone ever uses the dongle on anything beyond x86. I had no success in raising the author of the driver by e-mail, so the patch is not actually tested.

2009-09-19Driver-Core: extend devnode callbacks to provide permissionsKay Sievers
This allows subsytems to provide devtmpfs with non-default permissions for the device node. Instead of the default mode of 0600, null, zero, random, urandom, full, tty, ptmx now have a mode of 0666, which allows non-privileged processes to access standard device nodes in case no other userspace process applies the expected permissions.

Add range check on buffer sizes passed in from user space (max is 8*PAGE_SIZE) which will work for the most common spectrometers even at pages as small as 1K. Add kref to vst device structure to preserve reference to the usb object until we truly are done with it.

2008-10-17USB: ftdi-elan: Always pass usb_bulk_msg() a timeout in milliseconds.Sarah Sharp
The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be specified in milliseconds. The ftdi-elan driver converts milliseconds to jiffies before passing the timeout to usb_bulk_msg(). This is mostly harmless, since it will just lead to very long timeouts, but was obviously not the intent of the original author.

2008-10-17usb: vstusb.c : new driver for spectrometers used by Vernier Software & ↵Stephen Ware
Technology, Inc. This patch adds the vstusb driver to the drivers/usb/misc directory. This driver provides support for Vernier Software & Technology spectrometers, all made by Ocean Optics. The driver provides both IOCTL and read()/write() methods for sending raw data to spectrometers across the bulk channel. Each method allows for a configured timeout.

2008-10-17USB: drivers/usb/misc: Use an IS_ERR test rather than a NULL testJulien Brunel
In case of error, the function backlight_device_register returns an ERR pointer, but never returns a NULL pointer. So a NULL test that may come after a call to this function should be strengthened by an IS_ERR test. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match_bad_null_test@ expression x, E; statement S1,S2; @@ x = backlight_device_register(...) ... when != x = E * if (x != NULL) S1 else S2 // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
