2020-06-08test: v4l2_subdevice: list_formats: Port to use utils::hex() output helperUmang Jain
The hex stream output helper was introduced in f391048a7b98 ("libcamera: utils: Add hex stream output helper"). It simplifies writing hexadecimal values to an ostream which can be used in this test too. As the helper doesn't modify the stream configuration (refer to utils::hex() documentation), this eliminates the need of restoring the stream's format state as pointed out by the coverity scan.

2020-06-08v4l2: v4l2_camera_proxy: Fix segfault on restarting streamsPaul Elder
The V4L2 compatibility layer keeps track of the index of the next buffer to be dequeued, to handle VIDIOC_DQBUF. This index is set to 0 on startup and incremented (modulo #frames), and is otherwise never reset. This means that if the last handled frame index is not #frames-1, and the stream is restarted without restarting libcamera and the V4L2 compatilibity layer, the buffer index number won't match with the libcamera buffer index number, causing a segfault. Fix this by resetting the current buffer index to zero on VIDIOC_STREAMON.

2020-06-08v4l2: v4l2_compat: Add eventfd signaling to support pollingPaul Elder
To support polling, we need to be able to signal when data is available to be read (POLLIN), as well as events (POLLPRI). Add the necessary calls to eventfd to allow signaling POLLIN. We signal POLLIN by writing writing to the eventfd, and clear it by reading from the eventfd, upon VIDIOC_DQBUF. Note that eventfd does not support signaling POLLPRI, so we don't yet support V4L2 events.

2020-06-08v4l2: v4l2_camera_proxy: Don't return -EINVAL for zero sizeimage in REQBUFSPaul Elder
If VIDIOC_REQBUFS returns -EINVAL, it signals to the application that the requested buffer or memory type is not supported. If we return -EINVAL due to a zero sizeimage, then the application will think that we don't support a memory type that we actually do. We cannot error on a zero sizeimage, because reqbufs could be called merely to probe what IO methods we support; qv4l2, for example, called reqbufs once with userptr and once more with mmap, both times with count=1. On the other hand, sizeimage will be zero for formats whose size we don't know how to calculate, such as MJPEG. If we try to stream such formats anyway, we will get a floating point exception and crash. Issue a warning for now, and don't return -EINVAL, so that we can continue operation.

If any ipa_context instances are destroyed after the IPAManager is destroyed, then a segfault will occur, since the modules have been unloaded by the IPAManager and the context function pointers have been freed. Fix this by making the lifetime of the IPAManager explicit, and make the CameraManager construct and deconstruct (automatically, via a unique pointer) the IPAManager. Also update the IPA interface test to do the construction and deconstruction of the IPAManager, as it does not use the CameraManager.

2020-06-07libcamera: ipa_module: Fix implicit sign-extension in elfSectionUmang Jain
Given how the elfSection() function uses the sub-expression (idx * eHdr->e_shentsize) it has effectively two (16 bits, unsigned) operands. The sub-expression is promoted to type int (32 bits, signed) for multiplication and then added to eHdr->e_shoff, which is uint32_t on 32-bit platforms and uint64_t on 64-bit platforms. Since eHdr->e_shoff is unsigned, the integer conversion rules dictate that the other signed operand (i.e. the result of aforementioned sub-expression) will be converted to unsigned type too. This causes sign-extension for both of the above operands to match eHdr->e_shoff's type and should be avoided. The solution is to explicitly cast one of the operands of the sub-expression with unsigned int type. Hence, the other operand will be integer promoted and the resultant will also be of unsigned int type, not requiring to bother about a sign-extension.

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.
