[PATCH] sysctl: hide the sysctl proc inodes from selinux

Since the security checks are applied on each read and write of a sysctl file,
just like they are applied when calling sys_sysctl, they are redundant on the
standard VFS constructs.  Since it is difficult to compute the security labels
on the standard VFS constructs we just mark the sysctl inodes in proc private
so selinux won't even bother with them.

[PATCH] selinux: enhance selinux to always ignore private inodes

Hmmm...turns out to not be quite enough, as the /proc/sys inodes aren't truly
private to the fs, so we can run into them in a variety of security hooks
beyond just the inode hooks, such as security_file_permission (when reading
and writing them via the vfs helpers), security_sb_mount (when mounting other
filesystems on directories in proc like binfmt_misc), and deeper within the
security module itself (as in flush_unauthorized_files upon inheritance across
execve).  So I think we have to add an IS_PRIVATE() guard within SELinux, as
below.  Note however that the use of the private flag here could be confusing,
as these inodes are _not_ private to the fs, are exposed to userspace, and
security modules must implement the sysctl hook to get any access control over
them.

[PATCH] sysctl: reimplement the sysctl proc support

With this change the sysctl inodes can be cached and nothing needs to be done
when removing a sysctl table.

For a cost of 2K code we will save about 4K of static tables (when we remove
de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or
about half that on a 32bit arch.

The speed feels about the same, even though we can now cache the sysctl
dentries :(

We get the core advantage that we don't need to have a 1 to 1 mapping between
ctl table entries and proc files.  Making it possible to have /proc/sys vary
depending on the namespace you are in.  The currently merged namespaces don't
have an issue here but the network namespace under /proc/sys/net needs to have
different directories depending on which network adapters are visible.  By
simply being a cache different directories being visible depending on who you
are is trivial to implement.

I have done an audit and discovered that none of the current users of

duplicate sysctl entries.

By not using the enumeration in sysctl.h (or even understanding it) the SN
platform placed their arch specific xpc directory on top of CTL_KERN and only
because they didn't have 4 entries in their xpc directory got lucky and didn't
break glibc.

This is totally irresponsible.  So this patch entirely removes sys_sysctl
support from their sysctl code.  Hopefully they don't have ascii name
conflicts as well.

And now that they have no ABI numbers add them to the end instead of the
sysctl list instead of the head so nothing else will be overridden.

The patches in this series fall into several general categories.

- Removal of useless attempts to override the standard sysctls

- Registers of sysctl numbers in sysctl.h so someone else does not use
  the magic number and conflict.

- C99 conversions so it becomes possible to change the layout of
  struct ctl_table without breaking everything.

- Removal of useless claims of module ownership, in the proc dir entries

- Removal of sys_sysctl support where people had used conflicting sysctl
  numbers. Trying to break glibc or other applications by changing the
  ABI is not cool.  9 instances of this in the kernel seems a little
  extreme.

- General enhancements when I got the junk I could see out.

This patch:

Since x25 uses unique binary numbers inserting yourself at the head of the
search list for sysctls so you can override already registered sysctls is
pointless.
