kthread: silence bogus section mismatch warning
WARNING: kernel/built-in.o(.text+0x16910): Section mismatch:
reference to .init.text: (between 'kthreadd' and 'init_waitqueue_head')
comes because kernel/kthread.c:kthreadd() is not __init but calls
kthreadd_setup() which is __init. But this is ok, because kthreadd_setup()
is only ever called at init time, and then kthreadd() proceeds into its
"for (;;)" loop. We could mark kthreadd __init_refok, but kthreadd_setup()
with just one callsite and 4 lines in it (it's been that small since
10ab825bdef8df51) doesn't need to be a separate function at all -- so let's
just move those four lines at beginning of kthreadd() itself.

isofs: mounting to regular file may succeed
It turned out that mounting a corrupted ISO image to a regular file may
succeed, e.g. if an image was prepared as follows:
$ dd if=correct.iso of=bad.iso bs=4k count=8
We then can mount it to a regular file:
# mount -o loop -t iso9660 bad.iso /tmp/file
But mounting it to a directory fails with -ENOTDIR, simply because
the root directory inode doesn't have S_IFDIR set and the condition
in graft_tree() is met:
if (S_ISDIR(nd->dentry->d_inode->i_mode) !=
S_ISDIR(mnt->mnt_root->d_inode->i_mode))
return -ENOTDIR
This is because the root directory inode was read from an incorrect
block. It's supposed to be read from sbi->s_firstdatazone, which is
an absolute value and gets messed up in the case of an incorrect image.
In order to somehow circumvent this we have to check that the root
directory inode is actually a directory after all.

Fix user struct leakage with locked IPC shem segment
When user locks an ipc shmem segmant with SHM_LOCK ctl and the segment is
already locked the shmem_lock() function returns 0. After this the
subsequent code leaks the existing user struct:
== ipc/shm.c: sys_shmctl() ==
...
err = shmem_lock(shp->shm_file, 1, user);
if (!err) {
shp->shm_perm.mode |= SHM_LOCKED;
shp->mlock_user = user;
}
...
==
Other results of this are:
1. the new shp->mlock_user is not get-ed and will point to freed
memory when the task dies.
2. the RLIMIT_MEMLOCK is screwed on both user structs.
The exploit looks like this:
==
id = shmget(...);
setresuid(uid, 0, 0);
shmctl(id, SHM_LOCK, NULL);
setresuid(uid + 1, 0, 0);
shmctl(id, SHM_LOCK, NULL);

My solution is to return 0 to the userspace and do not change the
segment's user.

spidev supports more communications modes
The spidev driver doesn't currently expose all SPI communications modes to
userspace. This passes them all through to the driver.
Two of them are potentially troublesome, in the sense that they could cause
hardware conflicts on shared busses. It might be appropriate to add some
privilege checks for for those modes.

revert "x86, serial: convert legacy COM ports to platform devices"
Revert
7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26. It broke Sébastien Dugué's
machine and Jeff said (persuasively)
This seems like it will break decades-long-working stuff, in favor of
breaking new ground in our favorite area, "trusting the BIOS."
It's just not worth it for serial ports, IMO. Serial ports are something
that just shouldn't break at this late stage in the game. My new Intel
platform boxes don't even have serial ports, so I question the value of
messing with serial port probing even more... because... just wait a year,
and your box won't have a serial port either! :)
I certainly don't object to the use of platform devices (or isa_driver),
but the probe change seems questionable. That's sorta analagous to
rewriting the floppy driver probe routine. Sure you could do it... but why
risk all that damage and go through debugging all over again?
It seems clear from this report that we cannot, should not, trust BIOS for
something (a) so simple and (b) that has been working for over a decade.
Much discussion ensued and we've decided to have another go at all of this.

Do not trigger OOM-killer for high-order allocation failures
out_of_memory() may be called when an allocation is failing and the direct
reclaim is not making any progress. This does not take into account the
requested order of the allocation. If the request if for an order larger
than PAGE_ALLOC_COSTLY_ORDER, it is reasonable to fail the allocation
because the kernel makes no guarantees about those allocations succeeding.
This false OOM situation can occur if a user is trying to grow the hugepage
pool in a script like;
#!/bin/bash
REQUIRED=$1
echo 1 > /proc/sys/vm/hugepages_treat_as_movable
echo $REQUIRED > /proc/sys/vm/nr_hugepages
ACTUAL=`cat /proc/sys/vm/nr_hugepages`
while [ $REQUIRED -ne $ACTUAL ]; do
echo Huge page pool at $ACTUAL growing to $REQUIRED
echo $REQUIRED > /proc/sys/vm/nr_hugepages
ACTUAL=`cat /proc/sys/vm/nr_hugepages`
sleep 1
done
This is a reasonable scenario when ZONE_MOVABLE is in use but triggers OOM
easily on 2.6.23-rc1. This patch will fail an allocation for an order above
PAGE_ALLOC_COSTLY_ORDER instead of killing processes and retrying.
