2016-02-26KEYS: Use the symbol value for list size, updated by scripts/insert-sys-certMehmet Kayaalp
When a certificate is inserted to the image using scripts/writekey, the value of __cert_list_end does not change. The updated size can be found out by reading the value pointed by the system_certificate_list_size symbol.

2015-10-21KEYS: Provide a script to extract the sys cert list from a vmlinux fileDavid Howells
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.
