      KEYS: correct alignment of system_certificate_list content in assembly file · 62226983
      Hendrik Brueckner authored
      Apart from data-type specific alignment constraints, there are also
      architecture-specific alignment requirements.
      For example, on s390 symbols must be on even addresses implying a 2-byte
      alignment.  If the system_certificate_list_end symbol is on an odd address
      and if this address is loaded, the least-significant bit is ignored.  As a
      result, the load_system_certificate_list() fails to load the certificates
      because of a wrong certificate length calculation.
      
      To be safe, align system_certificate_list on an 8-byte boundary.  Also improve
      the length calculation of the system_certificate_list content.  Introduce a
      system_certificate_list_size (8-byte aligned because of unsigned long) variable
      that stores the length.  Let the linker calculate this size by introducing
      a start and end label for the certificate content.

      CONFIG_SYMBOL_PREFIX: cleanup. · b92021b0
      Rusty Russell authored
      We have CONFIG_SYMBOL_PREFIX, which three archs define to the string
      "_".  But Al Viro broke this in "consolidate cond_syscall and
      SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to
      do so.
      
      Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to
      prefix it so something.  So various places define helpers which are
      defined to nothing if CONFIG_SYMBOL_PREFIX isn't set:
      
      1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX.
      2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym)
      3) include/linux/export.h defines MODULE_SYMBOL_PREFIX.
      4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7)
      5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym)
      6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX
      7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if
         CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version
         for pasting.
      
      (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too).
      
      Let's solve this properly:
      1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX.
      2) Make linux/export.h usable from asm.
      3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR().
      4) Make everyone use them.
