| * [media] v4l2-event: Don't set sev->fh to NULL on unsubscribeHans de Goede2011-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting sev->fh to NULL causes problems for the del op added in the next patch of this series, since this op needs a way to get to its own data structures, and typically this will be done by using container_of on an embedded v4l2_fh struct. The reason the original code is setting sev->fh to NULL is to signal to users of the event framework that the unsubscription has happened, but since their is no shared lock between the event framework and users of it, this is inherently racy, and it also turns out to be unnecessary as long as both the event framework and the user of the framework do their own locking properly and the user guarantees that it holds no references to the subcribed_event structure after its del operation has been called. This is best explained by looking at the only code currently checking for sev->fh being set to NULL on unsubscribe, which is the v4l2-ctrls.c send_event function. Here is the relevant code from v4l2-ctrls: send_event(): if (sev->fh && (sev->fh != fh || (sev->flags & V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK))) v4l2_event_queue_fh(sev->fh, &ev); Now lets say that v4l2_event_unsubscribe and v4l2-ctrls: send_event() race on the same sev, then the following could happens: 1) send_event checks sev->fh, finds it is not NULL <thread switch> 2) v4l2_event_unsubscribe sets sev->fh NULL 3) v4l2_event_unsubscribe calls v4l2_ctrls del_event function, this blocks as the thread calling send_event holds the ctrl_lock <thread switch> 4) send_event calls v4l2_event_queue_fh(sev->fh, &ev) which not is equivalent to calling: v4l2_event_queue_fh(NULL, &ev) 5) oops, NULL pointer deref. Now again without setting sev->fh to NULL in v4l2_event_unsubscribe and without the (now senseless since always true) sev->fh != NULL check in 1) send_event is about to call v4l2_event_queue_fh(sev->fh, &ev) <thread switch> 2) v4l2_event_unsubscribe removes sev->list from the fh->subscribed list <thread switch> 3) send_event calls v4l2_event_queue_fh(sev->fh, &ev) 4) v4l2_event_queue_fh blocks on the fh_lock spinlock <thread switch> 5) v4l2_event_unsubscribe unlocks the fh_lock spinlock 6) v4l2_event_unsubscribe calls v4l2_ctrls del_event function, this blocks as the thread calling send_event holds the ctrl_lock <thread switch> 8) v4l2_event_queue_fh takes the fh_lock 7) v4l2_event_queue_fh calls v4l2_event_subscribed, does not find it since sev->list has been removed from fh->subscribed already -> does nothing 9) v4l2_event_queue_fh releases the fh_lock 10) the caller of send_event releases the ctrl lock (mutex) <thread switch> 11) v4l2_ctrls del_event takes the ctrl lock 12) v4l2_ctrls del_event removes sev->node from the ev_subs list 13) v4l2_ctrls del_event releases the ctrl lock 14) v4l2_event_unsubscribe frees the sev, to which no references are being held anymore Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] v4l2-event: Remove pending events from fh event queue when unsubscribingHans de Goede2011-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | The kev pointers inside the pending events queue (the available queue) of the fh point to data inside the sev, unsubscribing frees the sev, thus making these pointers point to freed memory! This patch fixes these dangling pointers in the available queue by removing all matching pending events on unsubscription.

| * | [media] v4l: Add AUTO option for the V4L2_CID_POWER_LINE_FREQUENCY controlSylwester Nawrocki2011-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct a driver what is the power line frequency so an appropriate filter can be used by the device to cancel flicker by compensating the light intensity ripple. Currently in the menu we have entries for 50 Hz and 60 Hz and for entirely disabling the anti-flicker filter. However some devices are capable of automatically detecting the frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Most users of the <media/soc_mediabus.h> header only need pixel code definitions, which are now located in the generic <linux/v4l2-mediabus.h> header.

| * | [media] V4L: soc-camera: make (almost) all client drivers re-usable outside ↵Guennadi Liakhovetski2011-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of the framework The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * | [media] V4L: dynamically allocate video_device nodes in subdevicesGuennadi Liakhovetski2011-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently only very few drivers actually use video_device nodes, embedded in struct v4l2_subdev. Allocate these nodes dynamically for those drivers to save memory for the rest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the sh_mobile_csi2 driver didn't attach to a client, normally, because the respective device connects to the SoC over the parallel CEU interface and doesn't use the CSI-2 controller, it also shouldn't call pm_runtime_put() on attempted disconnect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the internally cached pixel code, instead of the one, provided by the soc-camera, removes one more use of struct soc_camera_device in these drivers.
