From: Eric W. Biederman <ebiederm@xmission.com>

Since 2.2 we have been doing a chroot check to see if it is appropriate
to return a read or follow one of these magic symlinks.  The chroot
check was asking a question about the visibility of files to the
calling process and it was actually checking the destination process,
and not the files themselves.  That test was clearly bogus.

In my first pass through I simply fixed the test to check the visibility
of the files themselves.  That naive approach to fixing the permissions
was too strict and resulted in cases where a task could not even see
all of it's file descriptors.

What has disturbed me about relaxing this check is that file descriptors 
are per-process private things, and they are occasionaly used a user 
space capability tokens.  Looking a little farther into the symlink path 
on /proc I did find userid checks and a check for capability 
(CAP_DAC_OVERRIDE) so there were permissions checking this.

But I was still concerned about privacy.  Besides /proc there is only 
one other way to find out this kind of information, and that is ptrace. 
  ptrace has been around for a long time and it has a well established 
security model.

So after thinking about it I finally realized that the permission checks
that make sense are the permission checks applied to ptrace_attach.
The checks are simple per process, and won't cause nasty surprises for
people coming from less capable unices.

Unfortunately there is one case that the current ptrace_attach test
does not cover: Zombies and kernel threads.  Single stepping those
kinds of processes is impossible.  Being able to see which file
descriptors are open on these tasks is important to lsof, fuser and
friends.  So for these special processes I made the rule you can't
find out unless you have CAP_SYS_PTRACE.

These proc permission checks should now conform to the principle of
least surprise.  As well as using much less code to implement :)

Nice solution to this problem we were discussion, Eric!  I agree with 
the ptrace analogy and support it in the context of Linux-VServer.

Sorry for the missing References: header, blame Thunderbird :)

There are long lines here that have been wrapped, if your e-mail client 
does not support flowed content you will have to un-flow it before the 
patch will apply.

- A large procfs rework from Eric Biederman.

- The swap prefetching patch is back.



Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

  git fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
  mm-commits mailing list.

        echo "subscribe mm-commits" | mail majordomo@vger.kernel.org

- If you hit a bug in -mm and it's not obvious which patch caused it, it is
  most valuable if you can perform a bisection search to identify which patch
  introduced the bug.  Instructions for this process are at

        http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

  But beware that this process takes some time (around ten rebuilds and
  reboots), so consider reporting the bug first and if we cannot immediately
  identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
  list on any email.
