We currently have duplicated cleanup code in bpf_prog_put() and
bpf_prog_put_rcu() cleanup paths. Back then we decided that it was
not worth it to make it a common helper called by both, but with
the recent addition of resource charging, we could have avoided
the fix in commit ac00737f4e81 ("bpf: Need to call bpf_prog_uncharge_memlock
from bpf_prog_put") if we would have had only a single, common path.
We can simplify it further by assigning aux->prog only once during
allocation time.

Add a bpf_map_get() function that we're going to use later on and
align/clean the remaining helpers a bit so that we have them a bit
more consistent:
- __bpf_map_get() and __bpf_prog_get() that both work on the fd
struct, check whether the descriptor is eBPF and return the
pointer to the map/prog stored in the private data.
Also, we can return f.file->private_data directly, the function
signature is enough of a documentation already.
- bpf_map_get() and bpf_prog_get() that both work on u32 user fd,
call their respective __bpf_map_get()/__bpf_prog_get() variants,
and take a reference.

Since we're going to use anon_inode_getfd() invocations in more than just
the current places, make a helper function for both, so that we only need
to pass a map/prog pointer to the helper itself in order to get a fd. The
new helpers are called bpf_map_new_fd() and bpf_prog_new_fd().

This patch fixes following problems :
1) percpu_counter_init() can return an error, therefore
init_frag_mem_limit() must propagate this error so that
inet_frags_init_net() can do the same up to its callers.
2) If ip[46]_frags_ns_ctl_register() fail, we must unwind
properly and free the percpu_counter.
Without this fix, we leave freed object in percpu_counters
global list (if CONFIG_HOTPLUG_CPU) leading to crashes.
This bug was detected by KASAN and syzkaller tool
(http://github.com/google/syzkaller)

skb_set_owner_w() is called from various places that assume
skb->sk always point to a full blown socket (as it changes
sk->sk_wmem_alloc)
We'd like to attach skb to request sockets, and in the future
to timewait sockets as well. For these kind of pseudo sockets,
we need to take a traditional refcount and use sock_edemux()
as the destructor.
It is now time to un-inline skb_set_owner_w(), being too big.

All the mv88e6xxx drivers use the exact same code in their probe
function to lookup the switch name given its ID. Thus introduce a
mv88e6xxx_switch_id structure and a mv88e6xxx_lookup_name function in
the common mv88e6xxx code.
In the meantime make __mv88e6xxx_reg_{read,write} static since we do not

When adding a port to a bridge we initialize VLAN filtering on it. We do
not bail out in case an error occurred in nbp_vlan_init, as it can be
used as a non VLAN filtering bridge.
However, if VLAN filtering is required and an error occurred in
nbp_vlan_init, we should set vlgrp to NULL, so that VLAN filtering
functions (e.g. br_vlan_find, br_get_pvid) will know the struct is
invalid and will not try to access it.

IPv6 request sockets store a pointer to skb containing the SYN packet
to be able to transfer it to full blown socket when 3WHS is done
(ireq->pktopts -> np->pktoptions)
As explained in commit 5e0724d027f0 ("tcp/dccp: fix hashdance race for
passive sessions"), we must transfer the skb only if we won the
hashdance race, if multiple cpus receive the 'ack' packet completing
3WHS at the same time.

To further improve the RDS connection scalabilty on massive systems
where number of sockets grows into tens of thousands of sockets, there
is a need of larger bind hashtable. Pre-allocated 8K or 16K table is
not very flexible in terms of memory utilisation. The rhashtable
infrastructure gives us the flexibility to grow the hashtbable based
on use and also comes up with inbuilt efficient bucket(chain) handling.

net: encx24j600: Fix SPI driver module autoload
Recently I've been trying to fix module autoloading for all SPI drivers and
found that the encx24j600 driver does not fill module alias information due
missing a MODULE_DEVICE_TABLE() so module autload won't work and the driver
Kconfig symbol is tristate which means the driver can be built as a module.
But also the SPI id table is not correctly defined so this series fixes both
issues.

A driver's SPI id table is expected to be an array of struct spi_device_id
that ends with a zero-initialized sentinel entry. But this driver defines
the table as a single struct spi_device_id and sets .id_table to a pointer
to this struct.
But spi_match_id() has a loop that iterates while the struct spi_device_id
.name[0] is not NULL, so not having a sentinel can cause a NULL pointer
deference error.
This patch defines the SPI id table correctly as all other SPI drivers do.

This patch changes how the multipath hash is computed for locally
generated flows: now the hash comprises l4 information.
This allows better utilization of the available paths when the existing
flows have the same source IP and the same destination IP: with l3 hash,
even when multiple connections are in place simultaneously, a single path
will be used, while with l4 hash we can use all the available paths.
v2 changes:
- use get_hash_from_flowi4() instead of implementing just another l4 hash
function

This patch changes the use of struct timespec in
dccp_probe to use struct timespec64 instead. timespec uses a 32-bit
seconds field which will overflow in the year 2038 and beyond. timespec64
uses a 64-bit seconds field. Note that the correctness of the code isn't
changed, since the original code only uses the timestamps to compute a
small elapsed interval. This patch is part of a larger attempt to remove
instances of 32-bit timekeeping structures (timespec, timeval, time_t)
from the kernel so it is easier to identify where the real 2038 issues
are.

The SS_LISTEN socket state is defined by both af_vsock.c and
vmci_transport.c. This is risky since the value could be changed in one
file and the other would be out of sync.
Rename from SS_LISTEN to VSOCK_SS_LISTEN since the constant is not part
of enum socket_state (SS_CONNECTED, ...). This way it is clear that the
constant is vsock-specific.
The big text reflow in af_vsock.c was necessary to keep to the maximum
line length. Text is unchanged except for s/SS_LISTEN/VSOCK_SS_LISTEN/.

We cannot reliable calculate packet size on MSG_MORE corked sockets
and thus cannot decide if they are going to be fragmented later on,
so better not use CHECKSUM_PARTIAL in the first place.
The IPv6 code also intended to protect and not use CHECKSUM_PARTIAL in
the existence of IPv6 extension headers, but the condition was wrong. Fix
it up, too. Also the condition to check whether the packet fits into
one fragment was wrong and has been corrected.

Pull PCI fix from Bjorn Helgaas:
"Sorry for this last-minute update; it's been in -next for quite a
while, but I forgot about it until I started getting ready for the
merge window.
It's small and fixes a way a user could cause a panic via sysfs, so I
think it's worth getting it in v4.3.
NUMA:
- Prevent out of bounds access in sysfs numa_node override (Sasha Levin)"

Pull arm64 fixes from Will Deacon:
"Apologies for this being so late, but we've uncovered a few nasty
issues on arm64 which didn't settle down until yesterday and the fixes
all look suitable for 4.3. Of the four patches, three of them are
Cc'd to stable, with the remaining patch fixing an issue that only
took effect during the merge window.
Summary:
- Fix corruption in SWP emulation when STXR fails due to contention
- Fix MMU re-initialisation when resuming from a low-power state
- Fix stack unwinding code to match what ftrace expects
- Fix relocation code in the EFI stub when DRAM base is not 2MB aligned"

rbd requires stable pages, as it performs a crc of the page data before
they are send to the OSDs.
But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0
"mm: only enforce stable page writes if the backing device requires
it") it is not assumed anymore that block devices require stable pages.
This patch sets the necessary flag to get stable pages back for rbd.
In a ceph installation that provides multiple ext4 formatted rbd
devices "bad crc" messages appeared regularly (ca 1 message every 1-2
minutes on every OSD that provided the data for the rbd) in the
OSD-logs before this patch. After this patch this messages are pretty
much gone (only ca 1-2 / month / OSD).

====================
pull request (net-next): ipsec-next 2015-10-30
1) The flow cache is limited by the flow cache limit which
depends on the number of cpus and the xfrm garbage collector
threshold which is independent of the number of cpus. This
leads to the fact that on systems with more than 16 cpus
we hit the xfrm garbage collector limit and refuse new
allocations, so new flows are dropped. On systems with 16
or less cpus, we hit the flowcache limit. In this case, we
shrink the flow cache instead of refusing new flows.
We increase the xfrm garbage collector threshold to INT_MAX
to get the same behaviour, independent of the number of cpus.
2) Fix some unaligned accesses on sparc systems.
From Sowmini Varadhan.
3) Fix some header checks in _decode_session4. We may call
pskb_may_pull with a negative value converted to unsigened
int from pskb_may_pull. This can lead to incorrect policy
lookups. We fix this by a check of the data pointer position
before we call pskb_may_pull.
4) Reload skb header pointers after calling pskb_may_pull
in _decode_session4 as this may change the pointers into
the packet.
5) Add a missing statistic counter on inner mode errors.
Please pull or let me know if there are problems.

When adding vlans with multiple IFLA_BRIDGE_VLAN_INFO attrs set in AFSPEC,
we would wipe the vlan obj struct after the first IFLA_BRIDGE_VLAN_INFO.
Fix this by only clearing what's necessary on each IFLA_BRIDGE_VLAN_INFO
iteration.

====================
NFC 4.4 pull request
This is the NFC pull request for 4.4.
It's a bit bigger than usual, the 3 main culprits being:
- A new driver for Intel's Fields Peak NCI chipset. In order to
support this chipset we had to export a few NCI routines and
extend the driver NCI ops to not only support proprietary
commands but also core ones.
- Support for vendor commands for both STM drivers, st-nci
and st21nfca. Those vendor commands allow to run factory tests
through the NFC netlink interface.
- New i2c and SPI support for the Marvell driver, together with
firmware download support for this driver's core.
Besides that we also have:
- A few file renames in the STM drivers, to keep the naming
consistent between drivers.
- Some improvements and fixes on the NCI HCI layer, mostly to
properly reach a secure element over a legacy HCI link.
- A few fixes for the s3fwrn5 and trf7970a drivers.

Here are a some more Bluetooth patches for 4.4 which collected up during
the past week. The most important ones are from Kuba Pawlak for fixing
locking issues with SCO sockets. There's also a fix from Alexander Aring
for 6lowpan, a memleak fix from Julia Lawall for the btmrvl driver and
some cleanup patches from Marcel.
Please let me know if there are any issues pulling. Thanks.
