    KEYS: Provide a script to extract the sys cert list from a vmlinux file · 2221a6ee
    David Howells authored
    The supplied script takes a vmlinux file - and if necessary a System.map
    file - locates the system certificates list and extracts it to the named
    file.
    
    Call as:
    
        ./scripts/extract-sys-certs vmlinux certs
    
    if vmlinux contains symbols and:
    
        ./scripts/extract-sys-certs -s System.map vmlinux certs
    
    if it does not.
    
    It prints something like the following to stdout:
    
    	Have 27 sections
    	No symbols in vmlinux, trying System.map
    	Have 80088 symbols
    	Have 1346 bytes of certs at VMA 0xffffffff8201c540
    	Certificate list in section .init.data
    	Certificate list at file offset 0x141c540
    
    If vmlinux contains symbols then that is used rather than System.map - even
    if one is given.
