* cursor: add forward declaration for struct wl_bufferEmil Velikov2017-12-041-2/+2
| | | | | | | | | | | This makes the header self-contained, since the struct is considered opaque from waylad-cursor POV. As we're here move the wl_shm fwd. declaration alongside the others. Making it easier to read and track. Signed-off-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Yong Bakos <ybakos@humanoriented.com>
* cursor: Fix heap overflows when parsing malicious files.Tobias Stoeckmann2017-11-291-1/+7
| | | | | | | | | | | | | | | | | It is possible to trigger heap overflows due to an integer overflow while parsing images. The integer overflow occurs because the chosen limit 0x10000 for dimensions is too large for 32 bit systems, because each pixel takes 4 bytes. Properly chosen values allow an overflow which in turn will lead to less allocated memory than needed for subsequent reads.

* cursor: handle running out of buffer spacePekka Paalanen2013-12-021-16/+51
| | | | | | | | | | | | | | | | | | | | | If posix_fallocate is available, use it to detect when we are running out of buffer space. Propagate the failure properly through the various functions, stopping loading cursors but keeping the cursors that were already successfully loaded. This may result in an animated cursor not having all of its images, or a cursor theme not having all of its cursors. When that happens, the failure is NOT communicated to the application. Instead, the application will get NULL from wl_cursor_theme_get_cursor() for a cursor that was not loaded successfully. If an animated cursor is missing only some images, the animation is truncated but the cursor is still available. This patch relies on the commit "os: use posix_fallocate in creating sharable buffers" for defining HAVE_POSIX_FALLOCATE. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>
* os: use posix_fallocate in creating sharable buffersPekka Paalanen2013-12-021-1/+18
| | | | | | | | | | | | | | | | If posix_fallocate is available, use it instead of ftruncate. Unlike ftruncate, when posix_fallocate succeeds, it guarantees that you cannot run out of disk space, when later writing to the mmap()'ed file. With posix_fallocate, if os_create_anonymous_file() succeeds, the program cannot get a SIGBUS later from accessing this file via mmap. If there is insufficient disk space, the function fails and errno is set to ENOSPC. This is useful on systems, that limit the available buffer space by having XDG_RUNTIME_DIR on a small tmpfs.

| | | | | | | | Exporting unprefixed symbols is a pretty bad idea so don't do that. Instea of redefining it WL_ARRAY_LENGTH, we just move the define to our private header. The scanner generates code that uses ARRAY_LENGTH, but we can just make it count the number elements and emit an integer constant instead.

| | | | | | | | | This patch adds a few more directories to search for xcursor themes. Along with the weston patch, this adds the ability to configure weston to use an X11 cursor theme. Previously, wayland cursor would just look in the icons and pixmaps directories for cursor images to load. This adds the ability to also search in the x cursors directory.

* Introduce libwayland-cursor, a cursor helper libraryAnder Conselvan de Oliveira2012-05-226-0/+1372
The purpose of this library is to be the equivalent of libXcursor in the X world. This library is compatible with X cursor themes and loads them directly into an shm pool making it easy for the clients to get buffer for each cursor image. The code for handling the X cursor theme was taken from libXcursor. The files cursor/xcursor.[ch] are a stripped down version of that library containing only the interfaces necessary for implementing the wayland counterpart.
