====================
nf-next pull request
The following patchset contains Netfilter/IPVS updates for your
net-next tree. Regarding nf_tables, most updates focus on consolidating
the NAT infrastructure and adding support for masquerading. More
specifically, they are:
1) use __u8 instead of u_int8_t in arptables header, from
Mike Frysinger.
2) Add support to match by skb->pkttype to the meta expression, from
Ana Rey.
3) Add support to match by cpu to the meta expression, also from
Ana Rey.
4) A smatch warning about IPSET_ATTR_MARKMASK validation, patch from
Vytas Dauksa.
5) Fix netnet and netportnet hash types the range support for IPv4,
from Sergey Popovich.
6) Fix missing-field-initializer warnings resolved, from Mark Rustad.
7) Dan Carperter reported possible integer overflows in ipset, from
Jozsef Kadlecsick.
8) Filter out accounting objects in nfacct by type, so you can
selectively reset quotas, from Alexey Perevalov.
9) Move specific NAT IPv4 functions to the core so x_tables and
nf_tables can share the same NAT IPv4 engine.
10) Use the new NAT IPv4 functions from nft_chain_nat_ipv4.
11) Move specific NAT IPv6 functions to the core so x_tables and
nf_tables can share the same NAT IPv4 engine.
12) Use the new NAT IPv6 functions from nft_chain_nat_ipv6.
13) Refactor code to add nft_delrule(), which can be reused in the
enhancement of the NFT_MSG_DELTABLE to remove a table and its
content, from Arturo Borrero.
14) Add a helper function to unregister chain hooks, from
Arturo Borrero.
15) A cleanup to rename to nft_delrule_by_chain for consistency with
the new nft_*() functions, also from Arturo.
16) Add support to match devgroup to the meta expression, from Ana Rey.
17) Reduce stack usage for IPVS socket option, from Julian Anastasov.
18) Remove unnecessary textsearch state initialization in xt_string,
from Bojan Prtvar.
19) Add several helper functions to nf_tables, more work to prepare
the enhancement of NFT_MSG_DELTABLE, again from Arturo Borrero.
20) Enhance NFT_MSG_DELTABLE to delete a table and its content, from
Arturo Borrero.
21) Support NAT flags in the nat expression to indicate the flavour,
eg. random fully, from Arturo.
22) Add missing audit code to ebtables when replacing tables, from
Nicolas Dichtel.
23) Generalize the IPv4 masquerading code to allow its re-use from
nf_tables, from Arturo.
24) Generalize the IPv6 masquerading code, also from Arturo.
25) Add the new masq expression to support IPv4/IPv6 masquerading
from nf_tables, also from Arturo.

allow user space to generate eBPF programs
uapi/linux/bpf.h: eBPF instruction set definition
linux/filter.h: the rest
This patch only moves macro definitions, but practically it freezes existing
eBPF instruction set, though new instructions can still be added in the future.
These eBPF definitions cannot go into uapi/linux/filter.h, since the names
may conflict with existing applications.

Both SNAT and DNAT (and the upcoming masquerade) can have additional
configuration parameters, such as port randomization and NAT addressing
persistence. We can cover these scenarios by simply adding a flag
attribute for userspace to fill when needed.
The flags to use are defined in include/uapi/linux/netfilter/nf_nat.h:
NF_NAT_RANGE_MAP_IPS
NF_NAT_RANGE_PROTO_SPECIFIED
NF_NAT_RANGE_PROTO_RANDOM
NF_NAT_RANGE_PERSISTENT
NF_NAT_RANGE_PROTO_RANDOM_FULLY
NF_NAT_RANGE_PROTO_RANDOM_ALL
The caller must take care of not messing up with the flags, as they are
added unconditionally to the final resulting nf_nat_range.

====================
pull request: wireless-next 2014-09-08
Please pull this batch of updates intended for the 3.18 stream...
For the mac80211 bits, Johannes says:
"Not that much content this time. Some RCU cleanups, crypto
performance improvements, and various patches all over,
rather than listing them one might as well look into the
git log instead."
For the Bluetooth bits, Gustavo says:
"The changes consists of:
- Coding style fixes to HCI drivers
- Corrupted ack value fix for the H5 HCI driver
- A couple of Enhanced L2CAP fixes
- Conversion of SMP code to use common L2CAP channel API
- Page scan optimizations when using the kernel-side whitelist
- Various mac802154 and and ieee802154 6lowpan cleanups
- One new Atheros USB ID"
For the iwlwifi bits, Emmanuel says:
"We have a new big thing coming up which is called Dynamic Queue
Allocation (or DQA). This is a completely new way to work with the
Tx queues and it requires major refactoring. This is being done by
Johannes and Avri. Besides this, Johannes disables U-APSD by default
because of APs that would disable A-MPDU if the association supports
U-ASPD. Luca contributed to the power area which he was cleaning
up on the way while working on CSA. A few more random things here
and there."
For the Atheros bits, Kalle says:
"For ath6kl we had two small fixes and a new SDIO device id.
For ath10k the bigger changes are:
* support for new firmware version 10.2 (Michal)
* spectral scan support (Simon, Sven & Mathias)
* export a firmware crash dump file (Ben & me)
* cleaning up of pci.c (Michal)
* print pci id in all messages, which causes most of the churn (Michal)"
Beyond that, we have the usual collection of various updates to ath9k,
b43, mwifiex, and wil6210, as well as a few other bits here and there.
Please let me know if there are problems!

DSA is currently registering one packet_type function per EtherType it
needs to intercept in the receive path of a DSA-enabled Ethernet device.
Right now we have three of them: trailer, DSA and eDSA, and there might
be more in the future, this will not scale to the addition of new
protocols.
This patch proceeds with adding a new layer of abstraction and two new
functions:
dsa_switch_rcv() which will dispatch into the tag-protocol specific
receive function implemented by net/dsa/tag_*.c
dsa_slave_xmit() which will dispatch into the tag-protocol specific
transmit function implemented by net/dsa/tag_*.c
When we do create the per-port slave network devices, we iterate over
the switch protocol to assign the DSA-specific receive and transmit
operations.
A new fake ethertype value is used: ETH_P_XDSA to illustrate the fact
that this is no longer going to look like ETH_P_DSA or ETH_P_TRAILER
like it used to be.
This allows us to greatly simplify the check in eth_type_trans() and
always override the skb->protocol with ETH_P_XDSA for Ethernet switches
tagged protocol, while also reducing the number repetitive slave
netdevice_ops assignments.

You can use this to skip accounting objects when listing/resetting
via NFNL_MSG_ACCT_GET/NFNL_MSG_ACCT_GET_CTRZERO messages with the
NLM_F_DUMP netlink flag. The filtering covers the following cases:
1. No filter specified. In this case, the client will get old behaviour,
2. List/reset counter object only: In this case, you have to use
NFACCT_F_QUOTA as mask and value 0.
3. List/reset quota objects only: You have to use NFACCT_F_QUOTA_PKTS
as mask and value - the same, for byte based quota mask should be
NFACCT_F_QUOTA_BYTES and value - the same.
If you want to obtain the object with any quota type
(ie. NFACCT_F_QUOTA_PKTS|NFACCT_F_QUOTA_BYTES), you need to perform
two dump requests, one to obtain NFACCT_F_QUOTA_PKTS objects and
another for NFACCT_F_QUOTA_BYTES.

There are a few possible cases of where BSS data came from:
1) only a beacon has been received
2) only a probe response has been received
3) the driver didn't report what it received (this happens when
using cfg80211_inform_bss[_width]())
4) both probe response and beacon data has been received
Unfortunately, in the userspace API, a few things weren't there:
a) there was no way to differentiate cases 1) and 4) above
without comparing the data of the IEs
b) the TSF was always from the last frame, instead of being
exposed for beacon/probe response separately like IEs
Fix this by
i) exporting a new flag attribute that indicates whether or
not probe response data has been received - this addresses (a)
ii) exporting a BEACON_TSF attribute that holds the beacon's TSF
if a beacon has been received
iii) not exporting the beacon attributes in case (3) above as that
would just lead userspace into thinking the data actually came
from a beacon when that isn't clear
To implement this, track inside the IEs struct whether or not it
(definitely) came from a beacon.

Previous patch provided the interface definition and this patch prvides
implementation of new syscall.
Previously segment list was prepared in user space. Now user space just
passes kernel fd, initrd fd and command line and kernel will create a
segment list internally.
This patch contains generic part of the code. Actual segment preparation
and loading is done by arch and image specific loader. Which comes in
next patch.

memfd_create() is similar to mmap(MAP_ANON), but returns a file-descriptor
that you can pass to mmap(). It can support sealing and avoids any
connection to user-visible mount-points. Thus, it's not subject to quotas
on mounted file-systems, but can be used like malloc()'ed memory, but with
a file-descriptor to it.
memfd_create() returns the raw shmem file, so calls like ftruncate() can
be used to modify the underlying inode. Also calls like fstat() will
return proper information and mark the file as regular file. If you want
sealing, you can specify MFD_ALLOW_SEALING. Otherwise, sealing is not
supported (like on all other regular files).
Compared to O_TMPFILE, it does not require a tmpfs mount-point and is not
subject to a filesystem size limit. It is still properly accounted to
memcg limits, though, and to the same overcommit or no-overcommit
accounting as all user memory.

If two processes share a common memory region, they usually want some
guarantees to allow safe access. This often includes:
- one side cannot overwrite data while the other reads it
- one side cannot shrink the buffer while the other accesses it
- one side cannot grow the buffer beyond previously set boundaries
If there is a trust-relationship between both parties, there is no need
for policy enforcement. However, if there's no trust relationship (eg.,
for general-purpose IPC) sharing memory-regions is highly fragile and
often not possible without local copies. Look at the following two
use-cases:
1) A graphics client wants to share its rendering-buffer with a
graphics-server. The memory-region is allocated by the client for
read/write access and a second FD is passed to the server. While
scanning out from the memory region, the server has no guarantee that
the client doesn't shrink the buffer at any time, requiring rather
cumbersome SIGBUS handling.
2) A process wants to perform an RPC on another process. To avoid huge
bandwidth consumption, zero-copy is preferred. After a message is
assembled in-memory and a FD is passed to the remote side, both sides
want to be sure that neither modifies this shared copy, anymore. The
source may have put sensible data into the message without a separate
copy and the target may want to parse the message inline, to avoid a
local copy.
While SIGBUS handling, POSIX mandatory locking and MAP_DENYWRITE provide
ways to achieve most of this, the first one is unproportionally ugly to
use in libraries and the latter two are broken/racy or even disabled due
to denial of service attacks.
This patch introduces the concept of SEALING. If you seal a file, a
specific set of operations is blocked on that file forever. Unlike locks,
seals can only be set, never removed. Hence, once you verified a specific
set of seals is set, you're guaranteed that no-one can perform the blocked
operations on this file, anymore.
An initial set of SEALS is introduced by this patch:
- SHRINK: If SEAL_SHRINK is set, the file in question cannot be reduced
in size. This affects ftruncate() and open(O_TRUNC).
- GROW: If SEAL_GROW is set, the file in question cannot be increased
in size. This affects ftruncate(), fallocate() and write().
- WRITE: If SEAL_WRITE is set, no write operations (besides resizing)
are possible. This affects fallocate(PUNCH_HOLE), mmap() and
write().
- SEAL: If SEAL_SEAL is set, no further seals can be added to a file.
This basically prevents the F_ADD_SEAL operation on a file and
can be set to prevent others from adding further seals that you
don't want.
The described use-cases can easily use these seals to provide safe use
without any trust-relationship:
1) The graphics server can verify that a passed file-descriptor has
SEAL_SHRINK set. This allows safe scanout, while the client is
allowed to increase buffer size for window-resizing on-the-fly.
Concurrent writes are explicitly allowed.
2) For general-purpose IPC, both processes can verify that SEAL_SHRINK,
SEAL_GROW and SEAL_WRITE are set. This guarantees that neither
process can modify the data while the other side parses it.
Furthermore, it guarantees that even with writable FDs passed to the
peer, it cannot increase the size to hit memory-limits of the source
process (in case the file-storage is accounted to the source).
The new API is an extension to fcntl(), adding two new commands:
F_GET_SEALS: Return a bitset describing the seals on the file. This
can be called on any FD if the underlying file supports
sealing.
F_ADD_SEALS: Change the seals of a given file. This requires WRITE
access to the file and F_SEAL_SEAL may not already be set.
Furthermore, the underlying file must support sealing and
there may not be any existing shared mapping of that file.
Otherwise, EBADF/EPERM is returned.
The given seals are _added_ to the existing set of seals
on the file. You cannot remove seals again.
The fcntl() handler is currently specific to shmem and disabled on all
files. A file needs to explicitly support sealing for this interface to
work. A separate syscall is added in a follow-up, which creates files that
support sealing. There is no intention to support this on other
file-systems. Semantics are unclear for non-volatile files and we lack any
use-case right now. Therefore, the implementation is specific to shmem.

Pull second round of KVM changes from Paolo Bonzini:
"Here are the PPC and ARM changes for KVM, which I separated because
they had small conflicts (respectively within KVM documentation, and
with 3.16-rc changes). Since they were all within the subsystem, I
took care of them.
Stephen Rothwell reported some snags in PPC builds, but they are all
fixed now; the latest linux-next report was clean.
New features for ARM include:
- KVM VGIC v2 emulation on GICv3 hardware
- Big-Endian support for arm/arm64 (guest and host)
- Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)
And for PPC:
- Book3S: Good number of LE host fixes, enable HV on LE
- Book3S HV: Add in-guest debug support
This release drops support for KVM on the PPC440. As a result, the
PPC merge removes more lines than it adds. :)
I also included an x86 change, since Davidlohr tied it to an
independent bug report and the reporter quickly provided a Tested-by;
there was no reason to wait for -rc2"

"This is the powerpc new goodies for 3.17. The short story:
The biggest bit is Michael removing all of pre-POWER4 processor

ton of old cruft that has been bitrotting in a long while. It was
broken for quite a few versions already and nobody noticed. Nobody
uses those machines anymore. While at it, he cleaned up a bunch of
old dusty cabinets, getting rid of a skeletton or two.
Then, we have some base VFIO support for KVM, which allows assigning
of PCI devices to KVM guests, support for large 64-bit BARs on
"powernv" platforms, support for HMI (Hardware Management Interrupts)
on those same platforms, some sparse-vmemmap improvements (for memory
hotplug),
There is the usual batch of Freescale embedded updates (summary in the

drm/tegra: Changes for v3.17-rc1
Mostly some cleanup all over the place. Pitch alignment limitations of
the display controller are now honored and job submission is 64-bit
safe.
The SOR output (used for eDP) properly configures sync signal polarities
according to the display mode rather than hard-coding them to some value
and the number of bits per color is now taken from the panel rather than
hard-coded to properly support 24-bit vs. 18-bit panels.
The DSI controller now properly supports non-continuous clock mode.
GEM objects can now have their flags and tiling mode modified via IOCTLs
to allow buffers imported from Nouveau to be properly displayed. Newer
generations of the Tegra display controller can also detile block linear
buffers at scan-out time.
Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it
to be automatically loaded when built as a module.

Pull media updates from Mauro Carvalho Chehab:
- removal of sn9c102. This device driver was replaced a long time ago
by gspca
- solo6x10 and go7007 webcam drivers moved from staging into
mainstream. They were waiting for an API to allow setting the image
detection matrix
- SDR drivers moved from staging into mainstream: sdr-msi3101 (renamed
as msi2500) and rtl2832
- added SDR driver for airspy
- added demux driver: si2165
- rework at several RC subsystem, making the code for RC-5 SZ variant
to be added at the standard RC5 decoder
- added decoder for the XMP IR protocol
- tuner driver moved from staging into mainstream: msi3101 (renamed as
msi001)
- added documentation for some additional SDR pixfmt
- some device tree bindings documented
- added support for exynos3250 at s5p-jpeg
- remove the obsolete, unmaintained and broken mx1_camera driver
- added support for remote controllers at au0828 driver
- added a RC driver: sunxi-cir
- several driver fixes, enhancements and cleanups.

Add SOF_TIMESTAMPING_TX_ACK, a request for a tstamp when the last byte
in the send() call is acknowledged. It implements the feature for TCP.
The timestamp is generated when the TCP socket cumulative ACK is moved
beyond the tracked seqno for the first time. The feature ignores SACK
and FACK, because those acknowledge the specific byte, but not
necessarily the entire contents of the buffer up to that byte.

Kernel transmit latency is often incurred in the packet scheduler.
Introduce a new timestamp on transmission just before entering the
scheduler. When data travels through multiple devices (bonding,
tunneling, ...) each device will export an individual timestamp.
