* i2o: check copy_from_user() size parameterDan Carpenter2013-05-011-0/+10
| | | | | | | | | | | | | | Limit the size of the copy so we don't corrupt memory. Hopefully this can only be called by root, but fixing this makes the static checkers happier.

* dmi_scan: refactor dmi_scan_machine(), {smbios,dmi}_present()Ben Hutchings2013-05-011-43/+37
| | | | | | | | | | | | | | | | | | | | Move the calls to memcpy_fromio() up into the loop in dmi_scan_machine(), and move the signature checks back down into dmi_decode(). We need to check at 16-byte intervals but keep a 32-byte buffer for an SMBIOS entry, so shift the buffer after each iteration. Merge smbios_present() into dmi_present(), so we look for an SMBIOS signature at the beginning of the given buffer and then for a DMI signature at an offset of 16 bytes.

* lib/string_helpers: introduce generic string_unescapeAndy Shevchenko2013-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | There are several places in kernel where modules unescapes input to convert C-Style Escape Sequences into byte codes. The patch provides generic implementation of such approach. Test cases are also included into the patch.

* dump_stack: implement arch-specific hardware description in task dumpsTejun Heo2013-05-011-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86 and ia64 can acquire extra hardware identification information from DMI and print it along with task dumps; however, the usage isn't consistent. * x86 show_regs() collects vendor, product and board strings and print them out with PID, comm and utsname. Some of the information is printed again later in the same dump. * warn_slowpath_common() explicitly accesses the DMI board and prints it out with "Hardware name:" label. This applies to both x86 and ia64 but is irrelevant on all other archs. * ia64 doesn't show DMI information on other non-WARN dumps. This patch introduces arch-specific hardware description used by dump_stack(). It can be set by calling dump_stack_set_arch_desc() during boot and, if exists, printed out in a separate line with "Hardware name:" label. dmi_set_dump_stack_arch_desc() is added which sets arch-specific description from DMI data. It uses dmi_ids_string[] which is set from dmi_present() used for DMI debug message. It is superset of the information x86 show_regs() is using. The function is called from x86 and ia64 boot code right after dmi_scan_machine(). This makes the explicit DMI handling in warn_slowpath_common() unnecessary. Removed. show_regs() isn't yet converted to use generic debug information printing and this patch doesn't remove the duplicate DMI handling in x86 show_regs(). The next patch will unify show_regs() handling and remove the duplication. An example WARN dump follows.

| | | | | | | | | | | | | | | | | | | | | | | | | We're goning to use DMI identification for other purposes too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Sandy Bridge EDAC driver uses a register in the IMC_DDRIO CSR space to determine the type of DIMMs (registered or unregistered). But this device does not exist on some single socket Sandy Bridge servers. While the type of DIMMs is nice to know, it is not essential for this driver's other functions. So it seems harsh to have it refuse to load at all when it cannot find this device. Make the check for this device be optional. If it isn't present just report the memory type as "MEM_UNKNOWN".

So, move it to a common directory to make easier to re-use it - siano media driver updated to work with sms2270 devices - several work done in order to promote go7007 and solo6x1x out of staging (still, there are some pending issues) - several API compliance fixes at v4l2 drivers that don't behave as expected - as usual, lots of driver fixes, improvements, cleanups and new device addition at the existing drivers. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (831 commits) [media] cx88: make core less verbose [media] em28xx: fix oops at em28xx_dvb_bus_ctrl() [media] s5c73m3: fix indentation of the help section in Kconfig [media] cx25821-alsa: get rid of a __must_check warning [media] cx25821-video: declare cx25821_vidioc_s_std as static [media] cx25821-video: remove maxw from cx25821_vidioc_try_fmt_vid_cap [media] r820t: Remove a warning for an unused value [media] dib0090: Fix a warning at dib0090_set_EFUSE [media] dib8000: fix a warning [media] dib8000: Fix sub-channel range [media] dib8000: store dtv_property_cache in a temp var [media] dib8000: warning fix: declare internal functions as static [media] r820t: quiet gcc warning on n_ring [media] r820t: memory leak in release() [media] r820t: precendence bug in r820t_xtal_check() [media] videodev2.h: Remove the unused old V4L1 buffer types [media] anysee: Grammar s/report the/report to/ [media] anysee: Initialize ret = 0 in anysee_frontend_attach() [media] media: videobuf2: fix the length check for mmap [media] em28xx: save isoc endpoint number for DVB only if endpoint has alt settings with xMaxPacketSize != 0 ...

However, a "ret" value is used at cx25821 just to avoid the Kernel compilation to compain about it. That, however, produces another warning (with W=1): drivers/media/pci/cx25821/cx25821-alsa.c: In function 'cx25821_audio_fini': drivers/media/pci/cx25821/cx25821-alsa.c:727:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] With the current implementation of driver_for_each_device() and cx25821_alsa_exit_callback(), there's actually just one very unlikely condition where it will currently produce an error: if driver_find() returns NULL. Ok, there's not much that can be done, as it is on a driver's function that returns void, but it can at least print some message if the error happens.

So, better to change the check to consider any value bigger than 13 to mean that sub-channels should be disabled, fixing the warning and doing the right thing even if an invalid value is filled by userspace.

On all places it is used, a long list of struct reference is done. Instead of doing it, at the routines where it is used more than once, replace it by one temporary var. That may help the compiler to use a better code. It also makes easier to review the code, as the lines becomes closer to 80 columns, making them a way clearer to read. No functional changes.

| | | * | | [media] cx25821: remove cx25821-audio-upstream.c from the MakefileHans Verkuil2013-04-162-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The audio output is currently not used as this should be rewritten as an alsa driver. For the time being remove this source from the Makefile. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| | | * | | [media] cx25821: replace custom ioctls with write()Hans Verkuil2013-04-164-228/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ideally this should be implemented with vb2, but it'll do for now. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cx25821-video-upstream_ch2.c/h is practically identical to cx25821-video-upstream.c/h so add support for ch2 into cx25821-video-upstream.c instead. After this we can replace the custom ioctls with a proper write() interface. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop the custom ioctls and enable the video output nodes again, this time using standard ioctls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver does not have subdevices, so why call subdev ops?
