memcg: make mem_cgroup_read_stat() unsigned
mem_cgroup_read_stat() returns a page count by summing per cpu page
counters. The summing is racy wrt. updates, so a transient negative
sum is possible. Callers don't want negative values:
- mem_cgroup_wb_stats() doesn't want negative nr_dirty or nr_writeback.
This could confuse dirty throttling.
- oom reports and memory.stat shouldn't show confusing negative usage.
- tree_usage() already avoids negatives.
Avoid returning negative page counts from mem_cgroup_read_stat() and
convert it to unsigned.

memcg: fix dirty page migration
The problem starts with a file backed dirty page which is charged to a
memcg. Then page migration is used to move oldpage to newpage.
Migration:
- copies the oldpage's data to newpage
- clears oldpage.PG_dirty
- sets newpage.PG_dirty
- uncharges oldpage from memcg
- charges newpage to memcg
Clearing oldpage.PG_dirty decrements the charged memcg's dirty page
count.
However, because newpage is not yet charged, setting newpage.PG_dirty
does not increment the memcg's dirty page count. After migration
completes newpage.PG_dirty is eventually cleared, often in
account_page_cleaned(). At this time newpage is charged to a memcg so
the memcg's dirty page count is decremented which causes underflow
because the count was not previously incremented by migration. This
underflow causes balance_dirty_pages() to see a very large unsigned
number of dirty memcg pages which leads to aggressive throttling of
buffered writes by processes in non root memcg.
This issue:
- can harm performance of non root memcg buffered writes.
- can report too small (even negative) values in
memory.stat[(total_)dirty] counters of all memcg, including the root.
To avoid polluting migrate.c with #ifdef CONFIG_MEMCG checks, introduce
page_memcg() and set_page_memcg() helpers.
Test:
0) setup and enter limited memcg
mkdir /sys/fs/cgroup/test
echo 1G > /sys/fs/cgroup/test/memory.limit_in_bytes
echo $$ > /sys/fs/cgroup/test/cgroup.procs

mm: hugetlbfs: skip shared VMAs when unmapping private pages to satisfy a fault
SunDong reported the following on
https://bugzilla.kernel.org/show_bug.cgi?id=103841
I think I find a linux bug, I have the test cases is constructed. I
can stable recurring problems in fedora22(4.0.4) kernel version,
arch for x86_64. I construct transparent huge page, when the parent
and child process with MAP_SHARE, MAP_PRIVATE way to access the same
huge page area, it has the opportunity to lead to huge page copy on
write failure, and then it will munmap the child corresponding mmap
area, but then the child mmap area with VM_MAYSHARE attributes, child
process munmap this area can trigger VM_BUG_ON in set_vma_resv_flags
functions (vma - > vm_flags & VM_MAYSHARE).
There were a number of problems with the report (e.g. it's hugetlbfs that
triggers this, not transparent huge pages) but it was fundamentally
correct in that a VM_BUG_ON in set_vma_resv_flags() can be triggered that
looks like this
vma

set_vma_resv_flags+0x2d/0x30
The VM_BUG_ON is correct because private and shared mappings have
different reservation accounting but the warning clearly shows that the
VMA is shared.
When a private COW fails to allocate a new page then only the process
that created the VMA gets the page -- all the children unmap the page.
If the children access that data in the future then they get killed.
The problem is that the same file is mapped shared and private. During
the COW, the allocation fails, the VMAs are traversed to unmap the other
private pages but a shared VMA is found and the bug is triggered. This
patch identifies such VMAs and skips them.

mm/slab: fix unexpected index mapping result of kmalloc_size(INDEX_NODE+1)
Commit description is copied from the original post of this bug:
http://comments.gmane.org/gmane.linux.kernel.mm/135349
Kernels after v3.9 use kmalloc_size(INDEX_NODE + 1) to get the next
larger cache size than the size index INDEX_NODE mapping. In kernels
3.9 and earlier we used malloc_sizes[INDEX_L3 + 1].cs_size.
However, sometimes we can't get the right output we expected via
kmalloc_size(INDEX_NODE + 1), causing a BUG().
The mapping table in the latest kernel is like:
index = {0, 1, 2 , 3, 4, 5, 6, n}
size = {0, 96, 192, 8, 16, 32, 64, 2^n}
The mapping table before 3.10 is like this:
index = {0 , 1 , 2, 3, 4 , 5 , 6, n}
size = {32, 64, 96, 128, 192, 256, 512, 2^(n+3)}
The problem on my mips64 machine is as follows:
(1) When configured DEBUG_SLAB && DEBUG_PAGEALLOC && DEBUG_LOCK_ALLOC
&& DEBUG_SPINLOCK, the sizeof(struct kmem_cache_node) will be "150",
and the macro INDEX_NODE turns out to be "2": #define INDEX_NODE
kmalloc_index(sizeof(struct kmem_cache_node))
(2) Then the result of kmalloc_size(INDEX_NODE + 1) is 8.
(3) Then "if(size >= kmalloc_size(INDEX_NODE + 1)" will lead to "size
= PAGE_SIZE".
(4) Then "if ((size >= (PAGE_SIZE >> 3))" test will be satisfied and
"flags |= CFLGS_OFF_SLAB" will be covered.
(5) if (flags & CFLGS_OFF_SLAB)" test will be satisfied and will go to
"cachep->slabp_cache = kmalloc_slab(slab_size, 0u)", and the result
here may be NULL while kernel bootup.
(6) Finally,"BUG_ON(ZERO_OR_NULL_PTR(cachep->slabp_cache));" causes the
BUG info as the following shows (may be only mips64 has this problem):
This patch fixes the problem of kmalloc_size(INDEX_NODE + 1) and removes
the BUG by adding 'size >= 256' check to guarantee that all necessary
small sized slabs are initialized regardless sequence of slab size in
mapping table.

possible null pointer dereferences due to the new ordering and
initialization on port add/del, and patch 03 moves the "pvid" member in
the net_bridge_vlan_group struct in order to simplify code (similar to how
it was with the older struct). Patch 05 fixes adding a vlan on a port which
is pvid and doesn't have a global context yet.

Initialize msg/shm IPC objects before doing ipc_addid()
As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
having initialized the IPC object state. Yes, we initialize the IPC
object in a locked state, but with all the lockless RCU lookup work,
that IPC object lock no longer means that the state cannot be seen.
We already did this for the IPC semaphore code (see commit

Netfilter/IPVS updates for net-next
The following pull request contains Netfilter/IPVS updates for net-next
containing 90 patches from Eric Biederman.
The main goal of this batch is to avoid recurrent lookups for the netns
pointer, that happens over and over again in our Netfilter/IPVS code. The idea
consists of passing netns pointer from the hook state to the relevant functions
and objects where this may be needed.
You can find more information on the IPVS updates from Simon Horman's commit

Merge branch 'switchdev-callback'
Vivien Didelot says:
====================
net: switchdev: use specific switchdev_obj_*
This patchset changes switchdev add, del, dump operations from this:
int (*switchdev_port_obj_add)(struct net_device *dev,
struct switchdev_obj *obj,
struct switchdev_trans *trans);
int (*switchdev_port_obj_del)(struct net_device *dev,
struct switchdev_obj *obj);
int (*switchdev_port_obj_dump)(struct net_device *dev,
struct switchdev_obj *obj);
to something similar to the notifier_call callback of a notifier_block:
int (*switchdev_port_obj_add)(struct net_device *dev,
enum switchdev_obj_id id,
const void *obj,
struct switchdev_trans *trans);
int (*switchdev_port_obj_del)(struct net_device *dev,
enum switchdev_obj_id id,
const void *obj);
int (*switchdev_port_obj_dump)(struct net_device *dev,
enum switchdev_obj_id id, void *obj,
int (*cb)(void *obj));
This allows the caller to pass and expect back a specific switchdev_obj_*
structure (e.g. switchdev_obj_fdb) instead of the generic switchdev_obj one.
This will simplify pushing the callback function down to the drivers.
The first 3 patches get rid of the dev parameter of the dump callback, since it
is not always neeeded (e.g. vlan_dump) and some drivers (such as DSA drivers)
may not have easy access to it.
Patches 4 and 5 implement the change in the switchdev operations and its users.
Patch 6 extracts the inner switchdev_obj_* structures from switchdev_obj and
removes this last one.
v2: fix error spotted by kbuild (extra ';' inline switchdev_port_obj_dump).

Merge branch 'L3_master_device'
David Ahern says:
====================
net: L3 master device
The VRF device is essentially a Layer 3 master device used to associate
netdevices with a specific routing table and to influence FIB lookups
via 'ip rules' and controlling the oif/iif used for the lookup.
This series generalizes the VRF into L3 master device, l3mdev. Similar
to switchdev it has a Kconfig option and separate set of operations
in net_device allowing it to be completely compiled out if not wanted.
The l3mdev methods rely on the 'master' aspect and use of
netdev_master_upper_dev_get_rcu to retrieve the master device from a
given netdevice if it is enslaved to an L3_MASTER.
The VRF device is converted to use the l3mdev operations. At the end the
vrf_ptr is no longer and removed, as are all direct references to VRF.
The end result is a much simpler implementation for VRF.
Thanks to Nikolay for suggestions (eg., use of the master linkage which
is the key to making this work) and to Roopa, Andy and Shrijeet for
early reviews.

- added license header to l3mdev.c
