5e: the deb dropped /usr/lib/rustdesk into /etc/ld.so.conf.d so the private libdrmtap could be found by soname -- a system-wide search-path entry that lets it shadow a system library for every binary on the host, which Debian Policy 10.2 forbids. Resolve it by absolute path (/usr/lib/rustdesk/libdrmtap.so.0) at the dlopen site instead, with the bare sonames kept only as a dev fallback, and drop the ld.so.conf.d file and the ldconfig/try-restart postinst entirely (the .so is present at its absolute path right after unpack, so the pre-warm resolves with no linker-cache step). The dlopen site is this PR's own code, so this is in scope, not a follow-up. 6a: extract the _drm admission bound and the per-frame re-auth decision into pure helpers (drm_conn_admitted, drm_peer_authorized) and unit-test them: admission admits strictly below MAX_DRM_CONNS and rejects at/above it; re-auth passes root always, passes a non-root peer only while it equals the active-session uid, and fails closed on a switched-away, unknown-session, or unknown-peer case. (The /proc/exe-mismatch rejection is exercised by the accept-time authorize call; unit-testing it in isolation would need a second process with a different exe, so it stays an integration concern.)

scrap
Scrap records your screen! At least it does if you're on Windows, macOS, or Linux.
Usage
[dependencies]
scrap = "0.5"
Its API is as simple as it gets!
struct Display; /// A screen.
struct Frame; /// An array of the pixels that were on-screen.
struct Capturer; /// A recording instance.
impl Capturer {
/// Begin recording.
pub fn new(display: Display) -> io::Result<Capturer>;
/// Try to get a frame.
/// Returns WouldBlock if it's not ready yet.
pub fn frame<'a>(&'a mut self) -> io::Result<Frame<'a>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl Display {
/// The primary screen.
pub fn primary() -> io::Result<Display>;
/// All the screens.
pub fn all() -> io::Result<Vec<Display>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl<'a> ops::Deref for Frame<'a> {
/// A frame is just an array of bytes.
type Target = [u8];
}
The Frame Format
- The frame format is guaranteed to be packed BGRA.
- The width and height are guaranteed to remain constant.
- The stride might be greater than the width, and it may also vary between frames.
