Comment 1 Fabio Valentini 2026-05-08 21:06:22 UTC 
The Rust bindings for libssh2 (the libssh2-sys crate) are packaged in a way that unconditionally prunes the included library sources and links with the system libssh2 library, so there is nothing to do here - applications that use this crate will inherit the fix when the libssh2 is fixed.
