2020-05-28v4l2: Relicense V4L2 compatibility layer under LGPLLaurent Pinchart
The V4L2 compatibility layer is licensed under the GPL. It is compiled as a binary separate from libcamera.so, and is loaded into the address space of processes through LD_PRELOAD to intercept calls to the C library. It is our understanding and intent that the GPL license doesn't propagate to the binaries whose calls are intercepted, considering those binaries are not derivative work of the V4L2 compatibility layer and are not designed to be linked to the V4L2 compatibility layer. There is however a possibly grey area if binaries are packaged with a shell script wrapper that loads the V4L2 compatibility layer. This could lead to license-related issues if such packaging is performed by Linux distributions or system integrators. To clarify the intent and lift the doubts, relicense the V4L2 compatibility layer under the LGPL. The V4L2 compatibility layer code itself still benefits from the license protection, while its usage with third-party binaries is clearly allowed as intended.

2020-05-21libcamera: raspberry: Fix segfault in ~RPiCameraData()Jacopo Mondi
The RPiCameraData class destructor tries to stop its ipa_ instance without making sure it has been initialized. If the RPiCameraData gets destroyed before its ipa_ member is initialized, for example if the sensor initialization fails during the match() function, a nullptr dereference segfault is triggered preventing a graceful library teardown. Fix this by checking for ipa_ to be initialized before stopping it. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

2020-05-21include: linux: Update v4l2 ctrls for propertiesJacopo Mondi
The version of the v4l2-controls.h header file shipped by libcamera had deviated from the upstream one, as it included definitions for v4l2 controls that report camera properties, which were not accepted upstream at the time the header file was updated. Now that the controls definition has been accepted in the master branch of the linux-media kernel tree, update include/linux/v4l2-controls.h with the upstream-accepted definition of the control ids that describe camera properties. The control definition has been imported from the Linux kernel header files generated from the most recent linux-media master branch, at revision ad3a44cbd1b2e ("media: i2c: imx219: Parse and register properties") Instead of updating the whole header, just update the definition of V4L2 controls that describe camera properties. A full header update will be performed at a future Linux kernel release. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

2020-05-19libcamera: file_descriptor: Implement move semantics for constructorLaurent Pinchart
The FileDescriptor class, when constructed from a numerical file descriptor, duplicates the file descriptor and takes ownership of the copy. The caller has to close the original file descriptor manually if needed. This is inefficient as the dup() and close() calls could be avoided, but can also lead to resource leakage, as recently shown by commit 353fc4c22322 ("libcamera: v4l2_videodevice: Fix dangling file descriptor"). In an attempt to solve this problem, implement move semantics for the FileDescriptor constructor. The constructor taking a numerical file descriptor is split in two variants: - A "fd copy" constructor that takes a const lvalue reference to a numerical file descriptor and duplicates it (corresponding to the current behaviour). - A "fd move" constructor that takes a rvalue reference to a numerical file descriptor and takes ownership of it.

The FileDescriptor constructor used in V4L2VideoDevice::exportDmabufFd() creates a duplicate of the fd to store in the object. The original fd returned by the VIDIOC_EXPBUF ioctl was never closed, and left dangling. This would cause out of memory conditions if the camera stream was repeatedly started and stopped. This change closes the original fd explicitly, fixing the leak.

2020-05-16libcamera: Move IPA headers from include/ipa/ to include/libcamera/ipa/Laurent Pinchart
The IPA headers are installed into $prefix/include/libcamera/ipa/, but are located in the source tree in include/ipa/. This requires files within libcamera to include them with #include <ipa/foo.h> while a third party IPA would need to use #include <libcamera/ipa/foo.h> Not only is this inconsistent, it can create issues later if IPA headers need to include each other, as the first form of include directive wouldn't be valid once the headers are installed. Fix the problem by moving the IPA headers to include/libcamera/ipa/. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Jacopo Mondi <jacopo@jmondi.org>
2020-05-16libcamera: Move internal headers to include/libcamera/internal/Laurent Pinchart
The libcamera internal headers are located in src/libcamera/include/. The directory is added to the compiler headers search path with a meson include_directories() directive, and internal headers are included with (e.g. for the internal semaphore.h header) #include "semaphore.h" All was well, until libcxx decided to implement the C++20 synchronization library. The __threading_support header gained a #include <semaphore.h> to include the pthread's semaphore support. As include_directories() adds src/libcamera/include/ to the compiler search path with -I, the internal semaphore.h is included instead of the pthread version. Needless to say, the compiler isn't happy. Three options have been considered to fix this issue: - Use -iquote instead of -I. The -iquote option instructs gcc to only consider the header search path for headers included with the "" version. Meson unfortunately doesn't support this option. - Rename the internal semaphore.h header. This was deemed to be the beginning of a long whack-a-mole game, where namespace clashes with system libraries would appear over time (possibly dependent on particular system configurations) and would need to be constantly fixed. - Move the internal headers to another directory to create a unique namespace through path components. This causes lots of churn in all the existing source files through the all project. The first option would be best, but isn't available to us due to missing support in meson. Even if -iquote support was added, we would need to fix the problem before a new version of meson containing the required support would be released. The third option is thus the only practical solution available. Bite the bullet, and do it, moving headers to include/libcamera/internal/.

In an attempt to clarify the license terms of all files in the libcamera project, the build system files deserve particular attention. While they describe how the binaries are created, they are not themselves transformed into any part of binary distributions of the software, and thus don't influence the copyright on the binary packages. They are however subject to copyright, and thus influence the distribution terms of the source packages. Most of the meson.build files would not meet the threshold of originality criteria required for copyright protection. Some of the more complex meson.build files may be eligible for copyright protection. To avoid any ambiguity and uncertainty, state our intent to not assert copyrights on the build system files by putting them in the public domain with the CC0-1.0 license.
