David Howells [Thu, 4 Aug 2005 10:50:01 +0000]
[PATCH] Keys: Fix key management syscall interface bugs

This fixes five bugs in the key management syscall interface:

 (1) add_key() returns 0 rather than EINVAL if the key type is "".

     Checking the key type isn't "" should be left to lookup_user_key().

 (2) request_key() returns ENOKEY rather than EPERM if the key type begins
     with a ".".

     lookup_user_key() can't do this because internal key types begin with a
     ".".

 (3) Key revocation always returns 0, even if it fails.

 (4) Key read can return EAGAIN rather than EACCES under some circumstances.

     A key is permitted to by read by a process if it doesn't grant read
     access, but it does grant search access and it is in the process's
     keyrings. That search returns EAGAIN if it fails, and this needs
     translating to EACCES.

 (5) request_key() never adds the new key to the destination keyring if one is
     supplied.

     The wrong macro was being used to test for an error condition: PTR_ERR()
     will always return true, whether or not there's an error; this should've
     been IS_ERR().

15 years ago[PATCH] Remove suspend() calls from shutdown path
Benjamin Herrenschmidt [Thu, 4 Aug 2005 09:36:26 +0000]
[PATCH] Remove suspend() calls from shutdown path

This removes the calls to device_suspend() from the shutdown path that
were added sometime during 2.6.13-rc*.  They aren't working properly on
a number of configs (I got reports from both ppc powerbook users and x86
users) causing the system to not shutdown anymore.

I think it isn't the right approach at the moment anyway.  We have
already a shutdown() callback for the drivers that actually care about
shutdown and the suspend() code isn't yet in a good enough shape to be
so much generalized.  Also, the semantics of suspend and shutdown are
slightly different on a number of setups and the way this was patched in
provides little way for drivers to cleanly differenciate.  It should
have been at least a different message.

For 2.6.13, I think we should revert to 2.6.12 behaviour and have a
working suspend back.

[PATCH] ARM: 2833/2:  Remove support for WDIOF_MAGICCLOSE from sa1100-wdt

Patch from Ian Campbell

On PXA255 there is no way to disable the watchdog. Turning off OIER[E3]
as suggested in the existing comment does not work.

I posted a note to the ARM mailing list a little while ago asking for
opinions from people using SA1100. There was one reponse from Nico who
believes that the SA1100 is the same as the PXA255 in this respect.

You also asked me to involve the watchdog maintainer which I tried to
do but didn't hear anything back. There are only a couple of other
drivers which can't stop the watchdog and there seems to be no
consistancy regarding printing an error etc. I decided to print
something since that matches the case for all the other drivers when
NOWAYOUT is turned on.

Also, I changed the device .name to "watchdog" like most of the other
watchdogs. udev uses it as the device name (by default) and spaces etc.
get in the way.

Superceded 2833/1 because 2.6.13-rc4 caused rejects.

[PATCH] fix get_user_pages bug

Checking pte_dirty instead of pte_write in __follow_page is problematic
for s390, and for copy_one_pte which leaves dirty when clearing write.

So revert __follow_page to check pte_write as before, and make
do_wp_page pass back a special extra VM_FAULT_WRITE bit to say it has
done its full job: once get_user_pages receives this value, it no longer
requires pte_write in __follow_page.

But most callers of handle_mm_fault, in the various architectures, have
switch statements which do not expect this new case.  To avoid changing
them all in a hurry, make an inline wrapper function (using the old
name) that masks off the new bit, and use the extended interface with
double underscores.

Yes, we do have a call to do_wp_page from do_swap_page, but no need to
change that: in rare case it's needed, another do_wp_page will follow.

Linus Torvalds [Tue, 2 Aug 2005 21:55:40 +0000]
pci: make bus resource start address override minimum IO address

The reason we have PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO is because
we want to protect badly documented motherboard PCI resources and thus
don't want to allocate new resources in low IO/MEM space.

However, if we have already discovered a PCI bridge with a specified
resource base, that should override that decision.

This change will allow us to move the "careful" region upwards without
resulting in problems allocating resources in low mappings.  This was
brought on by us having allocated a bus resource at 0x1000, conflicting
with a undocumented VAIO Sony PI resources.

[PATCH] Obvious bugfix for yenta resource allocation

Recent changes (well, dating from 12 July) have broken cardbus on my
powerbook: I get 3 messages saying "no resource of type xxx available,
trying to continue", and if I plug in my wireless card, it complains
that there are no resources allocated to the card.  This all worked in
2.6.12.

Looking at the code in yenta_socket.c, function yenta_allocate_res,
it's obvious what is wrong: if we get to line 639 (i.e. there wasn't a
usable preassigned resource), we will always flow through to line 668,
which is the printk that I was seeing, even if a resource was
successfully allocated.  It looks to me as though there should be a
return statement after the two config_writel's in each of the 3
branches of the if statements, so that the function returns after
successfully setting up the resource.

The patch below adds these return statements, and with this patch,
cardbus works on my powerbook once again.

If CONFIG_NUMA is set, some POWER 4 systems will fail to boot.  This is

much sense.  Are there POWER 4 based systems with NUMA characteristics that
are presented by the firmware?  But, distros want one kernel for all systems
so NUMA is on by default in their kernels.  The patch handles those cases.

shmem_set_policy() and shmem_get_policy() are macros if !CONFIG_SHMEM, so this
doesn't work.

[PATCH] sys_set_mempolicy() doesnt check if mode < 0

A kernel BUG() is triggered by a call to set_mempolicy() with a negative
first argument.  This is because the mode is declared as an int, and the
validity check doesnt check < 0 values.  Alternatively, mode could be
declared as unsigned int or unsigned long.

Hirokazu Takata [Tue, 2 Aug 2005 04:11:35 +0000]
[PATCH] m32r: Fix local-timer event handling

There was a scheduling problem of the m32r SMP kernel; A process rarely
stopped and gave no responding but the other process have been handled by
the other CPU still lives, then if we did something in the other terminal
or something like that, the stopped process came back to life and continued
its operation...  (ex.  LMbench: lat_sig)

In the m32r SMP kernel, a local-timer event is delivered by using an
IPI(inter processor interrupts); LOCAL_TIMER_IPI.  And a function
smp_send_timer() is prepared to send the LOCAL_TIMER_IPI from the current
CPU to the other CPUs.

The funtion smp_send_timer() was placed and used in do_IRQ() in
former times (before 2.6.10-rc3-mm1 kernel), however, it was
unintentionally removed when arch/m32r/kernel/irq.c was modified to
employ the generic hardirq framework (CONFIG_GENERIC_HARDIRQ) in
my previous patch.

- It is important to write at first to MO_GP3_IO for cx88-tvaudio.c

- Use try_to_freeze() instead of refrigerator at msp3400.c

- Add new parameter to help identify radio chipsets at tuner module:
  show_i2c=1 will show 16 reading bytes from detected tuners.

- BTTV does generate some Unimplemented IOCTL log at tuner module:
  0x40046d11(dir=1,tp=0x6d,nr=17,sz=4) means that it is sending
  MSP3400 calls to non-msp3400 tuners. Warning eliminated.
  VIDIOSAUDIO is also called, so debug messages updated. It is still
  requiring IOCTL implementation.

- Added two more tuners.

- Add support for the SVideo input on the GDI Black Gold.

Linus Torvalds [Mon, 1 Aug 2005 18:14:49 +0000]
Fix get_user_pages() race for write access

There's no real guarantee that handle_mm_fault() will always be able to
break a COW situation - if an update from another thread ends up
modifying the page table some way, handle_mm_fault() may end up
requiring us to re-try the operation.

That's normally fine, but get_user_pages() ended up re-trying it as a
read, and thus a write access could in theory end up losing the dirty
bit or be done on a page that had not been properly COW'ed.

This makes get_user_pages() always retry write accesses as write
accesses by making "follow_page()" require that a writable follow has
the dirty bit set.  That simplifies the code and solves the race: if the
COW break fails for some reason, we'll just loop around and try again.

higher vclk values by changing set_vclk() according to the X drivers and

Acceleration is broken for all BLADE 3D chips for all versions of kernel
2.6 except for 32bit modes.  Most important reason is that the u32 col

[PATCH] remove sys_set_zone_reclaim()

This removes sys_set_zone_reclaim() for now.  While i'm sure Martin is
trying to solve a real problem, we must not hard-code an incomplete and
insufficient approach into a syscall, because syscalls are pretty much
for eternity.  I am quite strongly convinced that this syscall must not
hit v2.6.13 in its current form.

Firstly, the syscall lacks basic syscall design: e.g. it allows the
global setting of VM policy for unprivileged users. (!) [ Imagine an
Oracle installation and a SAP installation on the same NUMA box fighting
over the 'optimal' setting for this flag. What will they do? Will they
try to set the flag to their own preferred value every second or so? ]

Secondly, it was added based on a single datapoint from Martin:

 http://marc.theaimsgroup.com/?l=linux-mm&m=111763597218177&w=2

where Martin characterizes the numbers the following way:

 ' Run-to-run variability for "make -j" is huge, so these numbers aren't
   terribly useful except to see that with reclaim the benchmark still
   finishes in a reasonable amount of time. '

in other words: the fundamental problem has likely not been solved, only
a tendential move into the right direction has been observed, and a
handful of numbers were picked out of a set of hugely variable results,
without showing the variability data. How much variance is there
run-to-run?

I'd really suggest to first walk the walk and see what's needed to get
stable & predictable kernel compilation numbers on that NUMA box, before
adding random syscalls to tune a particular aspect of the VM ... which
approach might not even matter once the whole picture has been analyzed
and understood!

The third, most important point is that the syscall exposes VM tuning
internals in a completely unstructured way. What sense does it make to
have a _GLOBAL_ per-node setting for 'should we go to another node for
reclaim'? If then it might make sense to do this per-app, via numalib or
so.

The change is minimalistic in that it doesnt remove the syscall and the
underlying infrastructure changes, only the user-visible changes.  We
could perhaps add a CAP_SYS_ADMIN-only sysctl for this hack, a'ka
/proc/sys/vm/swappiness, but even that looks quite counterproductive
when the generic approach is that we are trying to reduce the number of
external factors in the VM balance picture.

The bug is evident when it is seen once. dst gc timer was backed off,
when gc queue is not empty. But this means that timer quickly backs off,
if at least one destination remains in use. Normally, the bug is invisible,
because adding new dst entry to queue cancels the backoff. But it shots
deadly with destination cache overflow when new destinations are not released
for long time f.e. after an interface goes down.

The fix is to cancel backoff when something was released.

While we are at it, move early UART mapping to TLB slot 0, so it can
survive longer during boot process (slot 1 is used by the first ioremap

change UART TLB entry size to 4K (256M is too much for a bunch of registers
:).  Squash some warnings on the way.
