      arch: um: fix error when linking vmlinux. · fb1770aa
      Lorenzo Colitti authored 
      
On gcc Ubuntu 4.8.4-2ubuntu1~14.04, linking vmlinux fails with:

arch/um/os-Linux/built-in.o: In function `os_timer_create':
/android/kernel/android/arch/um/os-Linux/time.c:51: undefined reference to `timer_create'
arch/um/os-Linux/built-in.o: In function `os_timer_set_interval':
/android/kernel/android/arch/um/os-Linux/time.c:84: undefined reference to `timer_settime'
arch/um/os-Linux/built-in.o: In function `os_timer_remain':
/android/kernel/android/arch/um/os-Linux/time.c:109: undefined reference to `timer_gettime'
arch/um/os-Linux/built-in.o: In function `os_timer_one_shot':
/android/kernel/android/arch/um/os-Linux/time.c:132: undefined reference to `timer_settime'
arch/um/os-Linux/built-in.o: In function `os_timer_disable':
/android/kernel/android/arch/um/os-Linux/time.c:145: undefined reference to `timer_settime'

This is because -lrt appears in the generated link commandline
after arch/um/os-Linux/built-in.o. Fix this by removing -lrt from
arch/um/Makefile and adding it to the UM-specific section of
scripts/link-vmlinux.sh.

      KEYS: Provide a script to extract a module signature · 4adc605e
      David Howells authored 
      
The supplied script takes a signed module file and extracts the tailmost
signature (there could theoretically be more than one) and dumps all or
part of it or the unsigned file to stdout.

Call as:

	scripts/extract-module-sig.pl -[0adnks] module-file >out

where the initial flag indicates which bit of the signed file you want dumping
to stdout:

 (*) "-0".  Dumps the unsigned data with the signature stripped.

 (*) "-a".  Dumps all of the signature data, including the magic number.

 (*) "-d".  Dumps the signature information block as a sequence of decimal
     	    numbers in text form with spaces between (crypto algorithm type,
     	    hash type, identifier type, signer's name length, key identifier
     	    length and signature length).

 (*) "-n".  Dumps the signer's name contents.

 (*) "-k".  Dumps the key identifier contents.

 (*) "-s".  Dumps the cryptographic signature contents.

In the case that the signature is a PKCS#7 (or CMS) message, -n and -k will
print a warning to stderr and dump nothing to stdout, but will otherwise
complete okay; the entire PKCS#7/CMS message will be dumped by "-s"; and "-d"
will show "0 0 2 0 0 <pkcs#7-msg-len>".

      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.
