c66f08be7e Add scaled time to taskstats based process accounting
This adds items to the taststats struct to account for user and system
time based on scaling the CPU frequency and instruction issue rates.

Adds account_(user|system)_time_scaled callbacks which architectures
can use to account for time using this mechanism.

72c2d5823f V3 file capabilities: alter behavior of cap_setpcap
The non-filesystem capability meaning of CAP_SETPCAP is that a process, p1,
can change the capabilities of another process, p2.  This is not the
meaning that was intended for this capability at all, and this
implementation came about purely because, without filesystem capabilities,
there was no way to use capabilities without one process bestowing them on
another.

Since we now have a filesystem support for capabilities we can fix the
implementation of CAP_SETPCAP.

The most significant thing about this change is that, with it in effect, no
process can set the capabilities of another process.

The capabilities of a program are set via the capability convolution
rules:

   pI(post-exec) = pI(pre-exec)
   pP(post-exec) = (X(aka cap_bset) & fP) | (pI(post-exec) & fI)
   pE(post-exec) = fE ? pP(post-exec) : 0

at exec() time.  As such, the only influence the pre-exec() program can
have on the post-exec() program's capabilities are through the pI
capability set.

The correct implementation for CAP_SETPCAP (and that enabled by this patch)
is that it can be used to add extra pI capabilities to the current process
- to be picked up by subsequent exec()s when the above convolution rules
are applied.

Here is how it works:

Let's say we have a process, p. It has capability sets, pE, pP and pI.
Generally, p, can change the value of its own pI to pI' where

   (pI' & ~pI) & ~pP = 0.

That is, the only new things in pI' that were not present in pI need to
be present in pP.

The role of CAP_SETPCAP is basically to permit changes to pI beyond
the above:

   if (pE & CAP_SETPCAP) {
      pI' = anything; /* ie., even (pI' & ~pI) & ~pP != 0  */
   }

This capability is useful for things like login, which (say, via
pam_cap) might want to raise certain inheritable capabilities for use
by the children of the logged-in user's shell, but those capabilities
are not useful to or needed by the login program itself.

One such use might be to limit who can run ping. You set the
capabilities of the 'ping' program to be "= cap_net_raw+i", and then
only shells that have (pI & CAP_NET_RAW) will be able to run
it. Without CAP_SETPCAP implemented as described above, login(pam_cap)
would have to also have (pP & CAP_NET_RAW) in order to raise this
capability and pass it on through the inheritable set.

7058cb02dd sysctl: deprecate sys_sysctl in a user space visible fashion.
After adding checking to register_sysctl_table and finding a whole new set
of bugs.  Missed by countless code reviews and testers I have finally lost
patience with the binary sysctl interface.

The binary sysctl interface has been sort of deprecated for years and
finding a user space program that uses the syscall is more difficult then
finding a needle in a haystack.  Problems continue to crop up, with the in
kernel implementation.  So since supporting something that no one uses is
silly, deprecate sys_sysctl with a sufficient grace period and notice that
the handful of user space applications that care can be fixed or replaced.

The /proc/sys sysctl interface that people use will continue to be
supported indefinitely.

This patch moves the tested warning about sysctls from the path where
sys_sysctl to a separate path called from both implementations of
sys_sysctl, and it adds a proper entry into
Documentation/feature-removal-schedule.

Allowing us to revisit this in a couple years time and actually kill
sys_sysctl.

49ffcf8f99 sysctl: update sysctl_check_table
Well it turns out after I dug into the problems a little more I was returning
a few false positives so this patch updates my logic to remove them.

- Don't complain about 0 ctl_names in sysctl_check_binary_path
  It is valid for someone to remove the sysctl binary interface
  and still keep the same sysctl proc interface.

- Count ctl_names and procnames as matching if they both don't
  exist.

- Only warn about missing min&max when the generic functions care.

fc6cd25b73 sysctl: Error on bad sysctl tables
After going through the kernels sysctl tables several times it has become
clear that code review and testing is just not effective in prevent
problematic sysctl tables from being used in the stable kernel.  I certainly
can't seem to fix the problems as fast as they are introduced.

Therefore this patch adds sysctl_check_table which is called when a sysctl
table is registered and checks to see if we have a problematic sysctl table.

The biggest part of the code is the table of valid binary sysctl entries, but
since we have frozen our set of binary sysctls this table should not need to
change, and it makes it much easier to detect when someone unintentionally
adds a new binary sysctl value.

As best as I can determine all of the several hundred errors spewed on boot up
now are legitimate.

f429cd37a2 sysctl: properly register the irda binary sysctl numbers
Grumble.  These numbers should have been in sysctl.h from the beginning if we
ever expected anyone to use them.  Oh well put them there now so we can find
them and make maintenance easier.

c65f92398e sysctl: remove the cad_pid binary sysctl path
It looks like we inadvertently killed the cad_pid binary sysctl support when
cap_pid was changed to be a struct pid.  Since no one has complained just
remove the binary path.

064b5bba0c sysctl: remove broken netfilter binary sysctls
No one has bothered to set strategy routine for the the netfilter sysctls that
return jiffies to be sysctl_jiffies.

So it appears the sys_sysctl path is unused and untested, so this patch
removes the binary sysctl numbers.

Which fixes the netfilter oops in 2.6.23-rc2-mm2 for me.

35834ca1e4 sysctl: simplify the pty sysctl logic
Instead of having a bunch of ifdefs in sysctl.c move all of the pty sysctl
logic into drivers/char/pty.c

As well as cleaning up the logic this prevents sysctl_check_table from
complaining that the root table has a NULL data pointer on something with
generic methods.

25398a158d sysctl: parport remove binary paths
The sysctl binary paths don't look as if they even code work, .data is not
filled in, and all of the proc_handlers look at extra1 and there is not
strategy routine.

So just kill the binary paths.

In addition this patch removes the setting of extra1 on directories.  It
doesn't look like the parport code ever examines it, and it's bad sysctl form.

0d135a4a8c sysctl: remove the binary interface for aio-nr, aio-max-nr, acpi_video_flags
aio-nr, aio-max-nr, acpi_video_flags are unsigned long values which sysctl
does not handle properly with a 64bit kernel and a 32bit user space.

Since no one is likely to be using the binary sysctl values and the ascii
interface still works, this patch just removes support for the binary sysctl
interface from the kernel.
