      x86: Disable CONFIG_X86_DECODER_SELFTEST in allmod/allyesconfigs · f8f20234
      Ingo Molnar authored
      It can take some time to validate the image, make sure
      {allyes|allmod}config doesn't enable it.
      
      I'd say randconfig will cover it often enough, and the failure is also
      borderline build coverage related: you cannot really make the decoder
      test fail via source level changes, only with changes in the build
      environment, so I agree with Andi that we can disable this one too.

      execve: use 'struct filename *' for executable name passing · c4ad8f98
      Linus Torvalds authored
      This changes 'do_execve()' to get the executable name as a 'struct
      filename', and to free it when it is done.  This is what the normal
      users want, and it simplifies and streamlines their error handling.
      
      The controlled lifetime of the executable name also fixes a
      use-after-free problem with the trace_sched_process_exec tracepoint: the
      lifetime of the passed-in string for kernel users was not at all
      obvious, and the user-mode helper code used UMH_WAIT_EXEC to serialize
      the pathname allocation lifetime with the execve() having finished,
      which in turn meant that the trace point that happened after
      mm_release() of the old process VM ended up using already free'd memory.
      
      To solve the kernel string lifetime issue, this simply introduces
      "getname_kernel()" that works like the normal user-space getname()
      function, except with the source coming from kernel memory.
      
      As Oleg points out, this also means that we could drop the tcomm[] array
      from 'struct linux_binprm', since the pathname lifetime now covers
      setup_new_exec().  That would be a separate cleanup.

      kbuild: don't enable DEBUG_INFO when building for COMPILE_TEST · 12b13835
      Linus Torvalds authored
      It really isn't very interesting to have DEBUG_INFO when doing compile
      coverage stuff (you wouldn't want to run the result anyway, that's kind
      of the whole point of COMPILE_TEST), and it currently makes the build
      take longer and use much more disk space for "all{yes,mod}config".
      
      There's somewhat active discussion about this still, and we might end up
      with some new config option for things like this (Andi points out that
      the silly X86_DECODER_SELFTEST option also slows down the normal
      coverage tests hugely), but I'm starting the ball rolling with this
      simple one-liner.
      
      DEBUG_INFO isn't that noticeable if you have tons of memory and a good
      IO subsystem, but it hurts you a lot if you don't - for very little
      upside for the common use.
