      perf: Handle new rbtree implementation · 871a0596
      Markus Trippelsdorf authored
      
      
      Perf build fails with the new rbtree implementation:
      
        ../../lib/rbtree.c:24:36: fatal error: linux/rbtree_augmented.h: No such file or directory compilation terminated.
      
      Fix by updating the Makefile and adding a btree_augmented.h
      wrapper.

        task_work stuff" breakage there.
      
        At that point the rest of kernel_thread/kernel_execve/sys_execve work
        can be done independently for different architectures.  The only
        pending bits that do depend on having all architectures converted are
        restrictred to fs/* and kernel/* - that'll obviously have to wait for
        the next cycle.
      
        I thought we'd have to wait for all of them done before we start
        eliminating the longjump-style insanity in kernel_execve(), but it
        turned out there's a very simple way to do that without flagday-style
        changes."

      vfs: embed struct filename inside of names_cache allocation if possible · 7950e385
      Jeff Layton authored
      
      
      In the common case where a name is much smaller than PATH_MAX, an extra
      allocation for struct filename is unnecessary. Before allocating a
      separate one, try to embed the struct filename inside the buffer first. If
      it turns out that that's not long enough, then fall back to allocating a
      separate struct filename and redoing the copy.

      audit: make audit_inode take struct filename · adb5c247
      Jeff Layton authored
      
      
      Keep a pointer to the audit_names "slot" in struct filename.
      
      Have all of the audit_inode callers pass a struct filename ponter to
      audit_inode instead of a string pointer. If the aname field is already
      populated, then we can skip walking the list altogether and just use it
      directly.

      ...and fix up the callers. For do_file_open_root, just declare a
      struct filename on the stack and fill out the .name field. For
      do_filp_open, make it also take a struct filename pointer, and fix up its
      callers to call it appropriately.
      
      For filp_open, add a variant that takes a struct filename pointer and turn
      filp_open into a wrapper around it.

      audit: allow audit code to satisfy getname requests from its names_list · 7ac86265
      Jeff Layton authored
      
      
      Currently, if we call getname() on a userland string more than once,
      we'll get multiple copies of the string and multiple audit_names
      records.
      
      Add a function that will allow the audit_names code to satisfy getname
      requests using info from the audit_names list, avoiding a new allocation
      and audit_names records.

      vfs: define struct filename and have getname() return it · 91a27b2a
      Jeff Layton authored
      
      
      getname() is intended to copy pathname strings from userspace into a
      kernel buffer. The result is just a string in kernel space. It would
      however be quite helpful to be able to attach some ancillary info to
      the string.
      
      For instance, we could attach some audit-related info to reduce the
      amount of audit-related processing needed. When auditing is enabled,
      we could also call getname() on the string more than once and not
      need to recopy it from userspace.
      
      This patchset converts the getname()/putname() interfaces to return
      a struct instead of a string. For now, the struct just tracks the
      string in kernel space and the original userland pointer for it.
      
      Later, we'll add other information to the struct as it becomes
      convenient.
