Struct LibsFooter 

pub struct LibsFooter {
    pub libs_offset: u64,
    pub libs_size: u64,
}

Footer appended to the stub binary to locate embedded runtime libraries.

The stub reads its own last 32 bytes to find the compressed libs bundle, extracts them to a cache directory, and dlopen’s libkrun from there. This keeps the .smolmachine sidecar cross-platform (no platform-specific libs).

Layout (32 bytes total):

Offset  Size  Field
0       8     magic ("SMOLLIBS")
8       4     version (u32 LE)
12      8     libs_offset (u64 LE) - offset to compressed libs blob
20      8     libs_size (u64 LE) - size of compressed libs blob
28      4     reserved (zeroes)

Fields

libs_offset: u64

Offset from start of file to the compressed libs blob.

libs_size: u64

Size of the compressed libs blob.
