[PATCH] correct slow acpi_pm rating

On Bob's machine clocksource is selecting PIT over the ACPI PM timer,
because he has the PIIX4 bug.  That bug drops the ACPI PM timers rating
to the same as the PIT, so that's why you're getting the PIT.

Realistically, the PIT is much slower then even the triple read ACPI PM,
so the de-ranking code is probably dropping it too far.

David S. Miller [Sun, 25 Mar 2007 03:36:25 +0000 (20:36 -0700)]
[IPV6]: Fix routing round-robin locking.

As per RFC2461, section 6.3.6, item #2, when no routers on the
matching list are known to be reachable or probably reachable we
do round robin on those available routes so that we make sure
to probe as many of them as possible to detect when one becomes
reachable faster.

Each routing table has a rwlock protecting the tree and the linked
list of routes at each leaf.  The round robin code executes during
lookup and thus with the rwlock taken as a reader.  A small local
spinlock tries to provide protection but this does not work at all
for two reasons:

1) The round-robin list manipulation, as coded, goes like this (with
   read lock held):

walk routes finding head and tail

spin_lock();
rotate list using head and tail
spin_unlock();

   While one thread is rotating the list, another thread can
   end up with stale values of head and tail and then proceed
   to corrupt the list when it gets the lock.  This ends up causing
   the OOPS in fib6_add() later onthat many people have been hitting.

2) All the other code paths that run with the rwlock held as
   a reader do not expect the list to change on them, they
   expect it to remain completely fixed while they hold the
   lock in that way.

So, simply stated, it is impossible to implement this correctly using
a manipulation of the list without violating the rwlock locking
semantics.

Reimplement using a per-fib6_node round-robin pointer.  This way we
don't need to manipulate the list at all, and since the round-robin
pointer can only ever point to real existing entries we don't need
to perform any locking on the changing of the round-robin pointer
itself.  We only need to reset the round-robin pointer to NULL when
the entry it is pointing to is removed.

The idea is from Thomas Graf and it is very similar to how this
was implemented before the advanced router selection code when in.

Thomas Graf [Sat, 24 Mar 2007 19:46:02 +0000 (12:46 -0700)]
[NET]: Fix fib_rules compatibility breakage

Based upon a patch from Patrick McHardy.

The fib_rules netlink attribute policy introduced in 2.6.19 broke
userspace compatibilty. When specifying a rule with "from all"
or "to all", iproute adds a zero byte long netlink attribute,
but the policy requires all addresses to have a size equal to
sizeof(struct in_addr)/sizeof(struct in6_addr), resulting in a
validation error.

Check attribute length of FRA_SRC/FRA_DST in the generic framework
by letting the family specific rules implementation provide the
length of an address. Report an error if address length is non
zero but no address attribute is provided. Fix actual bug by
checking address length for non-zero instead of relying on
availability of attribute.

[PATCH] dynticks: fix hrtimer rounding error in next_timer_interrupt

The rework of next_timer_interrupt() fixed the timer wheel bugs, but
invented a rounding error versus the next hrtimer event. This is caused
by the conversion of the hrtimer internal representation to relative
jiffies.

This causes bug #8100:
http://bugzilla.kernel.org/show_bug.cgi?id=8100

next_timer_interrupt() returns "now" in such a case and causes the code
in tick_nohz_stop_sched_tick() to trigger the timer softirq, which is
bogus as no timer is due for expiry. This results in an endless context
switching between idle and ksoftirqd until a timer is due for expiry.

Modify the hrtimer evaluation so that, it returns now + 1, when the
conversion results in a delta < 1 jiffie.

It's confirmed to resolve bug #8100

[PATCH] i386: clear segment register padding in core dumps

The segment register slots in struct pt_regs are padded to 32 bits.
Some of these are stored with instructions like "pushl %es", which
leaves the high 16 bits as they were.  So the high bits of these
fields in struct pt_regs contain kernel stack garbage.  These bits are
ignored by everything and never leak to user space, except in core
dumps.  The user struct pt_regs is always at the base of the thread's
kernel stack and so it seems unlikely the information that leaks from
here is ever worthwhile so as to be a security concern, but I'm not
sure about that.  It has been this way for ages; userland consumers of
core dumps all mask off these high bits themselves.  So it is not urgent.

This change masks off the padding bits of the segment register slots
in core dumps.  ptrace already masks off these high bits, so this
makes the values in core dumps consistent with what ptrace would
report just before the process died.

As I read the processor manuals, the cs and ss values will always be
padded with zero bits rather than stack garbage.  But unlike "pushl %es",
this is not simple to test with a userland program.  So I added the two
instructions rather than wonder if they are really never necessary.

I think that x86_64 does not have this problem (for either 32-bit or
64-bit processes).  It only uses "mov" instructions from segment
registers, which zero-extend.

[PATCH] FDPIC: fix the /proc/pid/stat representation of executable boundaries

Fix the /proc/pid/stat representation of executable boundaries.  It should
show the bounds of the executable, but instead shows the bounds of the
loader.

Before the patch is applied, the bug can be seen by examining, say, inetd:

# ps | grep inetd
  610         root          0   S   /usr/sbin/inetd -i
# cat /proc/610/maps

The code boundaries are 3233480704 to 3233523592, which are:

(gdb) p/x 3233480704
$1 = 0xc0bb0000
(gdb) p/x 3233523592
$2 = 0xc0bba788

Which corresponds to this line in the maps file:

c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157  /lib/ld-uClibc-0.9.28.so

Which is wrong.  After the patch is applied, the maps file is pretty much
identical (there's some minor shuffling of the location of some of the
anonymous VMAs), but the stat file is now:

# cat /proc/610/stat
610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 7 0 0 18 0 1 0 94392000722

3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0

The code boundaries are then 3276111872 to 3276141668, which are:

(gdb) p/x 3276111872
$1 = 0xc3458000
(gdb) p/x 3276141668
$2 = 0xc345f464

And these correspond to this line in the maps file instead:

c3458000-c345f464 r-xs 00000000 00:0b 16384612  /usr/sbin/inetd

Which is now correct.

[PATCH] i386: add command line option "local_apic_timer_c2_ok"

It turned out that it is almost impossible to trust ACPI, BIOS & Co.
regarding the C states. This was the reason to switch the local apic
timer off in C2 state already. OTOH there are sane and well behaving
systems, which get punished by that decision.

Allow the user to confirm that the local apic timer is trustworthy in C2
state. This keeps the default behaviour on the safe side.
