inet: Fix kmemleak in tcp_v4/6_syn_recv_sock and dccp_v4/6_request_recv_sock
If in either of the above functions inet_csk_route_child_sock() or
__inet_inherit_port() fails, the newsk will not be freed:

This happens, because sk_clone_lock initializes sk_refcnt to 2, and thus
a single sock_put() is not enough to free the memory. Additionally, things
like xfrm, memcg, cookie_values,... may have been initialized.
We have to free them properly.
This is fixed by forcing a call to tcp_done(), ending up in
inet_csk_destroy_sock, doing the final sock_put(). tcp_done() is necessary,
because it ends up doing all the cleanup on xfrm, memcg, cookie_values,
xfrm,...
Before calling tcp_done, we have to set the socket to SOCK_DEAD, to
force it entering inet_csk_destroy_sock. To avoid the warning in
inet_csk_destroy_sock, inet_num has to be set to 0.
As inet_csk_destroy_sock does a dec on orphan_count, we first have to
increase it.
Calling tcp_done() allows us to remove the calls to
tcp_clear_xmit_timer() and tcp_cleanup_congestion_control().
A similar approach is taken for dccp by calling dccp_done().
This is in the kernel since

ipv6: Change skb->data before using icmpv6_notify() to propagate redirect
In function ndisc_redirect_rcv(), the skb->data points to the transport header, but function icmpv6_notify() need the skb->data points to the inner IP packet. So before using icmpv6_notify() to propagate redirect, change skb->data to point the inner IP packet that triggered the sending of the Redirect, and introduce struct rd_msg to make it easy.

Highlights:
- Two new drivers from Pali Rohár and N900 hackers: rx51_battery and
bq2415x_charger. The drivers are a part of a solution to replace the
proprietary Nokia BME stack;
- Power supply core now registers devices with a thermal cooling
subsystem, so we can now automatically throttle charging. Thanks to
Ramakrishna Pallala!
- Device tree support for ab8500 and max8925_power drivers;
- Random fixups and enhancements for a bunch of drivers.

Pull networking fixes from David Miller:
"A pile of fixes in response to yesterday's big merge. The SCTP HMAC
thing hasn't been addressed yet, I'll take care of that myself if Neil
and Vlad don't show signs of life by tomorrow.
1) Use after free of SKB in tuntap code. Fix by Eric Dumazet,
reported by Dave Jones.
2) NFC LLCP code emits annoying kernel log message, triggerable by
the user. From Dave Jones.
3) Fix several endianness bugs noticed by sparse in the bridging
code, from Stephen Hemminger.
4) Ipv6 NDISC code doesn't take padding into account properly, fix
from YOSHIFUJI Hideaki.
5) Add missing docs to ethtool_flow_ext struct, from Yan Burman."

Merge branch 'akpm' (Andrew's patch-bomb)
Merge misc VM changes from Andrew Morton: "The rest of most-of-MM. The other MM bits await a slab merge. This patch includes the addition of a huge zero_page. Not a performance boost but it an save large amounts of physical memory in some situations. Also a bunch of Fujitsu engineers are working on memory hotplug. Which, as it turns out, was badly broken. About half of their patches are included here; the remainder are 3.8 material." However, this merge disables CONFIG_MOVABLE_NODE, which was totally broken. We don't add new features with "default y", nor do we add Kconfig questions that are incomprehensible to most people without any help text.

It includes a split-up of some of the OMAP clock data into separate files which adds to the diffstat, but gross delta is fairly reasonable. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQySrdAAoJEIwa5zzehBx3XBMQAJCgrE/I1vbuiENiVMLpQkN7 0Y5t89SwoALnme5jsM8vW/H0o6b163FfH+249UNs6dyk6MdCqqSv8cQVvSfCKRKn m4JTXS6njSnYgU025klNU9W3FyMuFcgH8b63+c5+sCcqfvdkxrjpNoKqAYNxQlgJ 6DHgHCKZP3JB1e2EFqViw0GJgZIjTNxlWvx8XLcAShSapQ+Ovq/iAcKo41o7ZadB 4zV//VkBMv0TLNTs6SoR0EO8qM+2nIUKE8fgPrRxvvb98tuasKPvlSq9VUeIjnYk kWjNTQYbD1IkrAMPYrwcpLU3xkEr14wrKDBtPK6GdCDcXzdyKq3fzROOXNsqrLmn Y8PkY+J39B59F0DKjyrCjasZyi0tQQV6ps5Xm2X2CB003GWEbo1yu+BodShYEyaL 7OvkLiVpOtq+LOYcsScHtOGdO9le2O3yZevNRvlrCDCvJUYbXNjaM9ZrWcQuTlJc oseYNSRPaIP5PMv2c+Xup9qh/dyAjj8g6gSi9BlDvwVOu/+Cf3laaCAXaFph22jT /m8fW2paiP5UJ0gSt1MLAGFxKi0YI/Qxck8G11LJxUwMZd3SIfOPUAY27tnNC4yL GRynOi3BFRMUAe/Leu2qgwEyoME5nHn+OmAKb36WTYH/HL+PGzHq84e+Wfdan8ha YcSKc1A52LSoYTi4XTUX =h2Qo -----END PGP SIGNATURE----- Merge tag 'pm-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC power management and clock changes from Olof Johansson: "This branch contains a largeish set of updates of power management and clock setup.

mm: introduce new field "managed_pages" to struct zone
Currently a zone's present_pages is calcuated as below, which is inaccurate and may cause trouble to memory hotplug. spanned_pages - absent_pages - memmap_pages - dma_reserve. During fixing bugs caused by inaccurate zone->present_pages, we found zone->present_pages has been abused. The field zone->present_pages may have different meanings in different contexts: 1) pages existing in a zone. 2) pages managed by the buddy system. For more discussions about the issue, please refer to: http://lkml.org/lkml/2012/11/5/866 https://patchwork.kernel.org/patch/1346751/ This patchset tries to introduce a new field named "managed_pages" to struct zone, which counts "pages managed by the buddy system". And revert zone->present_pages to count "physical pages existing in a zone", which also keep in consistence with pgdat->node_present_pages. We will set an initial value for zone->managed_pages in function free_area_init_core() and will adjust it later if the initial value is inaccurate. For DMA/normal zones, the initial value is set to: (spanned_pages - absent_pages - memmap_pages - dma_reserve) Later zone->managed_pages will be adjusted to the accurate value when the bootmem allocator frees all free pages to the buddy system in function free_all_bootmem_node() and free_all_bootmem(). The bootmem allocator doesn't touch highmem pages, so highmem zones' managed_pages is set to the accurate value "spanned_pages - absent_pages" in function free_area_init_core() and won't be updated anymore. This patch also adds a new field "managed_pages" to /proc/zoneinfo and sysrq showmem.

While profiling numa/core v16 with cgroup_disable=memory on the command line, I noticed mem_cgroup_count_vm_event() still showed up as high as 0.60% in perftop. This occurs because the function is called extremely often even when memcg is disabled.

mm: node_states: introduce N_MEMORY
We have N_NORMAL_MEMORY for standing for the nodes that have normal memory
with zone_type <= ZONE_NORMAL.
And we have N_HIGH_MEMORY for standing for the nodes that have normal or
high memory.
But we don't have any word to stand for the nodes that have *any* memory.
And we have N_CPU but without N_MEMORY.
Current code reuse the N_HIGH_MEMORY for this purpose because any node
which has memory must have high memory or normal memory currently.
A) But this reusing is bad for *readability*. Because the name
N_HIGH_MEMORY just stands for high or normal:
A.example 1)
mem_cgroup_nr_lru_pages():
for_each_node_state(nid, N_HIGH_MEMORY)
The user will be confused(why this function just counts for high or
normal memory node? does it counts for ZONE_MOVABLE's lru pages?)
until someone else tell them N_HIGH_MEMORY is reused to stand for
nodes that have any memory.
A.cont) If we introduce N_MEMORY, we can reduce this confusing
AND make the code more clearly:
A.example 2) mm/page_cgroup.c use N_HIGH_MEMORY twice:
One is in page_cgroup_init(void):
for_each_node_state(nid, N_HIGH_MEMORY) {
It means if the node have memory, we will allocate page_cgroup map for
the node. We should use N_MEMORY instead here to gaim more clearly.
The second using is in alloc_page_cgroup():
if (node_state(nid, N_HIGH_MEMORY))
addr = vzalloc_node(size, nid);
It means if the node has high or normal memory that can be allocated
from kernel. We should keep N_HIGH_MEMORY here, and it will be better
if the "any memory" semantic of N_HIGH_MEMORY is removed.
B) This reusing is out-dated if we introduce MOVABLE-dedicated node.
The MOVABLE-dedicated node should not appear in
node_stats[N_HIGH_MEMORY] nor node_stats[N_NORMAL_MEMORY],
because MOVABLE-dedicated node has no high or normal memory.
In x86_64, N_HIGH_MEMORY=N_NORMAL_MEMORY, if a MOVABLE-dedicated node
is in node_stats[N_HIGH_MEMORY], it is also means it is in
node_stats[N_NORMAL_MEMORY], it causes SLUB wrong.
The slub uses
for_each_node_state(nid, N_NORMAL_MEMORY)
and creates kmem_cache_node for MOVABLE-dedicated node and cause problem.
In one word, we need a N_MEMORY. We just intrude it as an alias to
N_HIGH_MEMORY and fix all im-proper usages of N_HIGH_MEMORY in late
patches.

Pass vma instead of mm and add address parameter. In most cases we already have vma on the stack. We provides split_huge_page_pmd_mm() for few cases when we have mm, but not vma. This change is preparation to huge zero pmd splitting implementation. Signed-off-by: Kirill A.

thp: do_huge_pmd_wp_page(): handle huge zero page
On write access to huge zero page we alloc a new huge page and clear it. If ENOMEM, graceful fallback: we create a new pmd table and set pte around fault address to newly allocated normal (4k) page.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal
Pull big execve/kernel_thread/fork unification series from Al Viro:
"All architectures are converted to new model. Quite a bit of that
stuff is actually shared with architecture trees; in such cases it's
literally shared branch pulled by both, not a cherry-pick.
A lot of ugliness and black magic is gone (-3KLoC total in this one):
- kernel_thread()/kernel_execve()/sys_execve() redesign.
We don't do syscalls from kernel anymore for either kernel_thread()
or kernel_execve():
kernel_thread() is essentially clone(2) with callback run before we
return to userland, the callbacks either never return or do
successful do_execve() before returning.
kernel_execve() is a wrapper for do_execve() - it doesn't need to
do transition to user mode anymore.
As a result kernel_thread() and kernel_execve() are
arch-independent now - they live in kernel/fork.c and fs/exec.c
resp. sys_execve() is also in fs/exec.c and it's completely
architecture-independent.
- daemonize() is gone, along with its parts in fs/*.c
- struct pt_regs * is no longer passed to do_fork/copy_process/
copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.
- sys_fork()/sys_vfork()/sys_clone() unified; some architectures
still need wrappers (ones with callee-saved registers not saved in
pt_regs on syscall entry), but the main part of those suckers is in
kernel/fork.c now."

ARM: arm-soc: SoC updates for 3.8
This contains the bulk of new SoC development for this merge window. Two new platforms have been added, the sunxi platforms (Allwinner A1x SoCs) by Maxime Ripard, and a generic Broadcom platform for a new series of ARMv7 platforms from them, where the hope is that we can keep the platform code generic enough to have them all share one mach directory. The new Broadcom platform is contributed by Christian Daudt. Highbank has grown support for Calxeda's next generation of hardware, ECX-2000. clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also taken on maintainership of the platform. Beyond this there has been a bunch of work from a number of people on converting more platforms to IRQ domains, pinctrl conversion, cleanup and general feature enablement across most of the active platforms. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQyLCjAAoJEIwa5zzehBx3AdQP/R+L3+EQMjiEWt/p7g/ql5Em 0SnP92CcGzrjgLTg9z1FeOazfOsGnkZAYUlDRkqfKobH3VqkhYFFtt1/0x0KMahm xcowHgMBOyimFdWT9vLK3J8U6DLui5XrEG9LGH2VL+lqmfjIyP/OOF3mVc0/+pV9 WTLAsYswdBRSeiNuF43kqlfrOwF6xsPLgiNMlc82w6BzHqoHu6dOif5M9MqWaApS V74DPmwLD371Tyit6aHqt3JOqpgiPSHlmxkzomK+5idcW3Pa7HnzzFYmx85dk/eN J2siqIkoOu7tEfjIbNZTL2MYoX4tUUKv4qZZ3IOl3YSWaV3P5ilMApF01XVrkk8E DWOMhzte9hC7L90W+/kCPLF1VyeAhCem2KQWUitO71fKur3r+3ZaUokNVvWzkJIL 7aduxAJOV2hfLgEqbjbjF3o4S8p63OV3kzivFJM1And15zDJo4+qqOh67+bPo4jj +R4du+SqzXriw4i3tDLGVpdjDffk4D41tbLzgkWAtvGyoP45yeYfHAzAh0pDFPRv ASfZVmZ5PhwAUAkIMnpC2sjgmxMYff3SYqmDgnsqXES7rbDH/hG+teymtHFTyUQp m+f60DNotSMcMvkLdvruLSB4aeTiwbfOqPn/g+aXYUlPuNMq1fVWgN7EJKWkamK4 nRwaJmLwx1/ojcVbpy2G =YMKB -----END PGP SIGNATURE----- Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC updates from Olof Johansson: "This contains the bulk of new SoC development for this merge window.

Merge branch 'for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup changes from Tejun Heo:
"A lot of activities on cgroup side. The big changes are focused on
making cgroup hierarchy handling saner.
- cgroup_rmdir() had peculiar semantics - it allowed cgroup
destruction to be vetoed by individual controllers and tried to
drain refcnt synchronously. The vetoing never worked properly and
caused good deal of contortions in cgroup. memcg was the last
reamining user. Michal Hocko removed the usage and cgroup_rmdir()
path has been simplified significantly. This was done in a
separate branch so that the memcg people can base further memcg
changes on top.
- The above allowed cleaning up cgroup lifecycle management and
implementation of generic cgroup iterators which are used to
improve hierarchy support.
- cgroup_freezer updated to allow migration in and out of a frozen
cgroup and handle hierarchy. If a cgroup is frozen, all descendant
cgroups are frozen.
- netcls_cgroup and netprio_cgroup updated to handle hierarchy
properly.
- Various fixes and cleanups.
- Two merge commits. One to pull in memcg and rmdir cleanups (needed
to build iterators). The other pulled in cgroup/for-3.7-fixes for
device_cgroup fixes so that further device_cgroup patches can be
stacked on top."
