* [media] v4l: v4l2_subdev userspace crop APIAntti Koskipaa2011-03-22
| | | | | | | | | | This patch adds the VIDIOC_SUBDEV_S_CROP and G_CROP ioctls to the userland API. CROPCAP is not implemented because it's redundant.

* [media] v4l: v4l2_subdev userspace frame interval APILaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | The three new ioctl VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, VIDIOC_SUBDEV_G_FRAME_INTERVAL and VIDIOC_SUBDEV_S_FRAME_INTERVAL can be used to enumerate and configure a subdev's frame rate from userspace. Two new video::g/s_frame_interval subdev operations are introduced to support those ioctls. The existing video::g/s_parm operations are deprecated and shouldn't be used anymore.

* [media] v4l: v4l2_subdev userspace format APILaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

* [media] v4l: Add a media_device pointer to the v4l2_device structureLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | The pointer will later be used to register/unregister media entities when registering/unregistering a v4l2_subdev or a video_device. With the introduction of media devices, device drivers need to store a pointer to a driver-specific structure in the device's drvdata. v4l2_device can't claim ownership of the drvdata anymore. To maintain compatibility with drivers that rely on v4l2_device storing a pointer to itself in the device's drvdata, v4l2_device_register() will keep doing so if the drvdata is NULL.

* [media] media: Pipelines and media streamsLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | Drivers often need to associate pipeline objects to entities, and to take stream state into account when configuring entities and links. The pipeline API helps drivers manage that information. When starting streaming, drivers call media_entity_pipeline_start(). The function marks all entities connected to the given entity through enabled links, either directly or indirectly, as streaming. Similarly, when stopping the stream, drivers call media_entity_pipeline_stop(). The media_entity_pipeline_start() function takes a pointer to a media pipeline and stores it in every entity in the graph. Drivers should embed the media_pipeline structure in higher-level pipeline structures and can then access the pipeline through the media_entity structure. Link configuration will fail with -EBUSY by default if either end of the link is a streaming entity, unless the link is marked with the MEDIA_LNK_FL_DYNAMIC flag.

| | | | | | | | | | | | | | | | Due to the wide differences between drivers regarding power management needs, the media controller does not implement power management. However, the media_entity structure includes a use_count field that media drivers can use to track the number of users of every entity for power management needs.

* [media] media: Entities, pads and linksLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As video hardware pipelines become increasingly complex and configurable, the current hardware description through v4l2 subdevices reaches its limits. In addition to enumerating and configuring subdevices, video camera drivers need a way to discover and modify at runtime how those subdevices are connected. This is done through new elements called entities, pads and links. An entity is a basic media hardware building block. It can correspond to a large variety of logical blocks such as physical hardware devices (CMOS sensor for instance), logical hardware devices (a building block in a System-on-Chip image processing pipeline), DMA channels or physical connectors. A pad is a connection endpoint through which an entity can interact with other entities. Data (not restricted to video) produced by an entity flows from the entity's output to one or more entity inputs. Pads should not be confused with physical pins at chip boundaries. A link is a point-to-point oriented connection between two pads, either on the same entity or on different entities. Data flows from a source pad to a sink pad. Links are stored in the source entity. To make backwards graph walk faster, a copy of all links is also stored in the sink entity. The copy is known as a backlink and is only used to help graph traversal. The entity API is made of three functions: - media_entity_init() initializes an entity. The caller must provide an array of pads as well as an estimated number of links. The links array is allocated dynamically and will be reallocated if it grows beyond the initial estimate. - media_entity_cleanup() frees resources allocated for an entity. It must be called during the cleanup phase after unregistering the entity and before freeing it. - media_entity_create_link() creates a link between two entities. An entry in the link array of each entity is allocated and stores pointers to source and sink pads. When a media device is unregistered, all its entities are unregistered automatically. The code is based on Hans Verkuil <hverkuil@xs4all.nl> initial work.

They were fixed, but the old ioctl names are still there, maintained to avoid breaking binary compatibility: There's no sense on preserving those forever, as it is very doubtful that someone would try to use a such old binary with a modern kernel. Removing them will allow us to remove some magic done at the V4L ioctl handler. Note that any application compiled with a videodev2.h from 2.6.7 or later will be using the correct ioctls.

Give the DNS resolver key its own read handler that returns the error cached in key->type_data.x[0] as an error rather than crashing. Also make the kenter() at the beginning of dns_resolver_instantiate() limit the amount of data it prints, since the data is not necessarily NUL-terminated. The buggy code was added in: commit 4a2d789267e00b5a1175ecd2ddefcc78b83fbf09 Author: Wang Lei <wang840925@gmail.com> Date: Wed Aug 11 09:37:58 2010 +0100 Subject: DNS: If the DNS server returns an error, allow that to be cached [ver #2] This can trivially be reproduced by any user with the following program compiled with -lkeyutils: #include <stdlib.h> #include <keyutils.h> #include <err.h> static char payload[] = "#dnserror=6"; int main() { key_serial_t key; key = add_key("dns_resolver", "a", payload, sizeof(payload), KEY_SPEC_SESSION_KEYRING); if (key == -1) err(1, "add_key"); if (keyctl_read(key, NULL, 0) == -1) err(1, "read_key"); return 0; } What should happen is that keyctl_read() reports error 6 (ENXIO) to the user: dns-break: read_key: No such device or address but instead the kernel oopses. This cannot be reproduced with the 'keyutils add' or 'keyutils padd' commands as both of those cut the data down below the NUL termination that must be included in the data. Without this dns_resolver_instantiate() will return -EINVAL and the key will not be instantiated such that it can be read.

| | | | | | | | | | | | | | | | | | | | | | | | | | On systems where the temperature sensor is actually used, the BIOS is likely to have locked the alarm registers. In that case, all writes through the corresponding sysfs files would be silently ignored. To prevent this, detect the locks and make the affected sysfs files read-only.
