md: Fix check for overlapping devices.
The checks in overlaps() expect all parameters either in block-based

rdev->data_offset arguments as well as two rdev->size arguments, the
former being sector counts while the latter are measured in 1K blocks.
This could cause rdev_size_store() to accept an invalid size from user
space. Fix it by passing only sector-based quantities to overlaps().

tun: Persistent devices can get stuck in xoff state
The scenario goes like this. App stops reading from tun/tap.
TX queue gets full and driver does netif_stop_queue().
App closes fd and TX queue gets flushed as part of the cleanup.
Next time the app opens tun/tap and starts reading from it but
the xoff state is not cleared. We're stuck.
Normally xoff state is cleared when netdev is brought up. But
in the case of persistent devices this happens only during
initial setup.
The fix is trivial. If device is already up when an app opens
it we clear xoff state and that gets things moving again.

"The register %ecx looks innocent but is very important here. The disassembly:

So %ecx has been loaded from %edx... which is 0x6b6b6b6b/POISON_FREE.
(0x6b6b6b6b >> 2 == 0x1adadada.)
%ecx is the counter for the memset, from here:
memset(object, 0, c->objsize);
i.e. %ecx was loaded from c->objsize, so "c" must have been freed.
Where did "c" come from? Uh-oh...
c = get_cpu_slab(s, smp_processor_id());
This looks like it has very much to do with CPU hotplug/unplug. Is
there a race between SLUB/hotplug since the CPU slab is used after it
has been freed?"
Good analysis.
Yeah, it's possible that a caller of kmem_cache_alloc() -> slab_alloc()
can be migrated on another CPU right after local_irq_restore() and
before memset(). The inital cpu can become offline in the mean time (or
a migration is a consequence of the CPU going offline) so its
'kmem_cache_cpu' structure gets freed ( slab_cpuup_callback).
At some point of time the caller continues on another CPU having an
obsolete pointer...

exec: fix stack excutability without PT_GNU_STACK
Kernel Bugzilla #11063 points out that on some architectures (e.g. x86_32)
exec'ing an ELF without a PT_GNU_STACK program header should default to an
executable stack; but this got broken by the unlimited argv feature because
stack vma is now created before the right personality has been established:
so breaking old binaries using nested function trampolines.
Therefore re-evaluate VM_STACK_FLAGS in setup_arg_pages, where stack
vm_flags used to be set, before the mprotect_fixup. Checking through
our existing VM_flags, none would have changed since insert_vm_struct:
so this seems safer than finding a way through the personality labyrinth.

Fix PREEMPT_RCU without HOTPLUG_CPU
PREEMPT_RCU without HOTPLUG_CPU is broken. The rcu_online_cpu is called
to initially populate rcu_cpu_online_map with all online CPUs when the
hotplug event handler is installed, and also to populate the map with
CPUs as they come online. The former case is meant to happen with and
without HOTPLUG_CPU, but without HOTPLUG_CPU, the rcu_offline_cpu
function is no-oped -- while it still gets called, it does not set the
rcu CPU map.
With a blank RCU CPU map, grace periods get to tick by completely
oblivious to active RCU read side critical sections. This results in
free-before-grace bugs.

ipv6: fix race between ipv6_del_addr and DAD timer
Consider the following scenario:
ipv6_del_addr(ifp)
ipv6_ifa_notify(RTM_DELADDR, ifp)
ip6_del_rt(ifp->rt)
after returning from the ipv6_ifa_notify and enabling BH-s

ifp->timer fires and:
addrconf_dad_timer(ifp)
addrconf_dad_completed(ifp)

then return back to the ipv6_del_addr and:
in6_ifa_put(ifp)
inet6_ifa_finish_destroy(ifp)
dst_release(&ifp->rt->u.dst)
After this we have an ifp->rt inserted into fib6 lists, but
queued for gc, which in turn can result in oopses in the
fib6_run_gc. Maybe some other nasty things, but we caught
only the oops in gc so far.
The solution is to disarm the ifp->timer before flushing the

[S390] protect _PAGE_SPECIAL bit against mprotect
David Gibson [Tue, 8 Jul 2008 05:58:16 +0000 (15:58 +1000)]
Correct hash flushing from huge_ptep_set_wrprotect()
As Andy Whitcroft recently pointed out, the current powerpc version of
huge_ptep_set_wrprotect() has a bug. It just calls ptep_set_wrprotect()
which in turn calls pte_update() then hpte_need_flush() with the 'huge'
argument set to 0. This will cause hpte_need_flush() to flush the wrong
hash entries (of any). Andy's fix for this is already in the powerpc
tree as commit
016b33c4958681c24056abed8ec95844a0da80a3.
I have confirmed this is a real bug, not masked by some other
synchronization, with a new testcase for libhugetlbfs. A process write
a (MAP_PRIVATE) hugepage mapping, fork(), then alter the mapping and
have the child incorrectly see the second write.
Therefore, this should be fixed for 2.6.26, and for the stable tree.
Here is a suitable patch for 2.6.26, which I think will also be suitable
for the stable tree (neither of the headers in question has been changed
much recently).
It is cut down slighlty from Andy's original version, in that it does
not include a 32-bit version of huge_ptep_set_wrprotect(). Currently,
hugepages are not supported on any 32-bit powerpc platform. When they
are, a suitable 32-bit version can be added - the only 32-bit hardware
which supports hugepages does not use the conventional hashtable MMU and
so will have different needs anyway.

Revert "PCI: Correct last two HP entries in the bfsort whitelist"
This reverts commit
a1676072558854b95336c8f7db76b0504e909a0a. It duplicates
the change from
8d64c781f0c5fbfdf8016bd1634506ff2ad1376a and only one should be
applied, otherwise some of the Dell quirks are lost.
Thanks to Tony Camuso for catching this.

[UML] fix gcc ICEs and unresolved externs
There are various constraints on the use of unit-at-a-time:
- i386 uses no-unit-at-a-time for pre-4.0 (not 4.3)
- x86_64 uses unit-at-a-time always
Uli reported a crash on x86_64 with gcc 4.1.2 with unit-at-a-time,
resulting in commit
c0a18111e571138747a98af18b3a2124df56a0d1
Ingo reported a gcc internal error with gcc 4.3 with no-unit-at-a-timem,
resulting in
22eecde2f9034764a3fd095eecfa3adfb8ec9a98
Benny Halevy is seeing extern inlines not resolved with gcc 4.3 with
no-unit-at-a-time
This patch reintroduces unit-at-a-time for gcc >= 4.0, bringing back the
possibility of Uli's crash. If that happens, we'll debug it.
I started seeing both the internal compiler errors and unresolved
inlines on Fedora 9. This patch fixes both problems, without so far
reintroducing the crash reported by Uli.

powerpc: Fix unterminated of_device_id array in legacy_serial.c
A recent patch to legacy_serial.c factored out some code by
using the of_match_node() facility to match a node against
an array of possible matches. However, the patch didn't properly
terminate the array causing potential crashes in cases where no
match is found. In addition, the name of the array was poorly
chosen for a static symbol making debugging harder.
