It's a fairly big one, with the following highlights:
- NFC digital layer implementation: Most NFC chipsets implement the NFC
digital layer in firmware, but others have more basic functionalities
and expect the host to implement the digital layer. This layer sits
below the NFC core.
- Sony's port100 support: This is "soft" NFC USB dongle that expects the
digital layer to be implemented on the host. This is the first user of
our NFC digital stack implementation.
- Secure element API: We now provide a netlink API for enabling,
disabling and discovering NFC attached (embedded or UICC ones) secure
elements. With some userspace help, this allows us to support NFC
payments.
Only the pn544 driver currently supports that API.
- NCI SPI fixes and improvements: In order to support NCI devices over
SPI, we fixed and improved our NCI/SPI implementation. The currently
most deployed NFC NCI chipset, Broadcom's bcm2079x, supports that mode
and we're planning to use our NCI/SPI framework to implement a
driver for it.
- pn533 fragmentation support in target mode: This was the only missing
feature from our pn533 impementation. We now support fragmentation in
both Tx and Rx modes, in target mode.

netfilter updates: nf_tables pull request
The following patchset contains the current original nf_tables tree
condensed in 17 patches. I have organized them by chronogical order
since the original nf_tables code was released in 2009 and by
dependencies between the different patches.
The patches are:
1) Adapt all existing hooks in the tree to pass hook ops to the
hook callback function, required by nf_tables, from Patrick McHardy.
2) Move alloc_null_binding to nf_nat_core, as it is now also needed by
nf_tables and ip_tables, original patch from Patrick McHardy but
required major changes to adapt it to the current tree that I made.
3) Add nf_tables core, including the netlink API, the packet filtering
engine, expressions and built-in tables, from Patrick McHardy. This
patch includes accumulated fixes since 2009 and minor enhancements.
The patch description contains a list of references to the original
patches for the record. For those that are not familiar to the
original work, see [1], [2] and [3].
4) Add netlink set API, this replaces the original set infrastructure
to introduce a netlink API to add/delete sets and to add/delete
set elements. This includes two set types: the hash and the rb-tree
sets (used for interval based matching). The main difference with
ipset is that this infrastructure is data type agnostic. Patch from
Patrick McHardy.
5) Allow expression operation overload, this API change allows us to
provide define expression subtypes depending on the configuration
that is received from user-space via Netlink. It is used by follow
up patches to provide optimized versions of the payload and cmp
expressions and the x_tables compatibility layer, from Patrick
McHardy.
6) Add optimized data comparison operation, it requires the previous
patch, from Patrick McHardy.
7) Add optimized payload implementation, it requires patch 5, from
Patrick McHardy.
8) Convert built-in tables to chain types. Each chain type have special
semantics (filter, route and nat) that are used by userspace to
configure the chain behaviour. The main chain regarding iptables
is that tables become containers of chain, with no specific semantics.
However, you may still configure your tables and chains to retain
iptables like semantics, patch from me.
9) Add compatibility layer for x_tables. This patch adds support to
use all existing x_tables extensions from nf_tables, this is used
to provide a userspace utility that accepts iptables syntax but
used internally the nf_tables kernel core. This patch includes
missing features in the nf_tables core such as the per-chain
stats, default chain policy and number of chain references, which
are required by the iptables compatibility userspace tool. Patch
from me.
10) Fix transport protocol matching, this fix is a side effect of the
x_tables compatibility layer, which now provides a pointer to the
transport header, from me.
11) Add support for dormant tables, this feature allows you to disable
all chains and rules that are contained in one table, from me.
12) Add IPv6 NAT support. At the time nf_tables was made, there was no
NAT IPv6 support yet, from Tomasz Bursztyka.
13) Complete net namespace support. This patch register the protocol
family per net namespace, so tables (thus, other objects contained
in tables such as sets, chains and rules) are only visible from the
corresponding net namespace, from me.
14) Add the insert operation to the nf_tables netlink API, this requires
adding a new position attribute that allow us to locate where in the
ruleset a rule needs to be inserted, from Eric Leblond.
15) Add rule batching support, including atomic rule-set updates by
using rule-set generations. This patch includes a change to nfnetlink
to include two new control messages to indicate the beginning and
the end of a batch. The end message is interpreted as the commit
message, if it's missing, then the rule-set updates contained in the
batch are aborted, from me.
16) Add trace support to the nf_tables packet filtering core, from me.
17) Add ARP filtering support, original patch from Patrick McHardy, but
adapted to fit into the chain type infrastructure. This was recovered
to be used by nft userspace tool and our compatibility arptables
userspace tool.
There is still work to do to fully replace x_tables [4] [5] but that can
be done incrementally by extending our netlink API. Moreover, looking at
netfilter-devel and the amount of contributions to nf_tables we've been
getting, I think it would be good to have it mainstream to avoid accumulating
large patchsets skip continuous rebases.
I tried to provide a reasonable patchset, we have more than 100 accumulated
patches in the original nf_tables tree, so I collapsed many of the small
fixes to the main patch we had since 2009 and provide a small batch for
review to netdev, while trying to retain part of the history.
For those who didn't give a try to nf_tables yet, there's a quick howto
available from Eric Leblond that describes how to get things working [6].
Comments/reviews welcome.
Thanks!

Instead of creating an new function pointer to report errors we are just
reusing state_change for that and there is a simple reason for this, one
place in the l2cap_core.c code needs, in a locked sk, set both the sk_state
and sk_err. If we create two different functions for this we would need to
release the lock between the two operation putting the socket in non
desired state.
The change is transparent to the l2cap_core.c code, user that only needs
to set the state won't need any modification.
This is another step of an ongoing work to make l2cap_core.c totally
independent from l2cap's struct sock.

commit 578bc3ef1e ("ipvs: reorganize dest trash") added
rcu_barrier() on cleanup to wait dest users and schedulers
like LBLC and LBLCR to put their last dest reference.
Using rcu_barrier with many namespaces is problematic.
Trying to fix it by freeing dest with kfree_rcu is not
a solution, RCU callbacks can run in parallel and execution
order is random.
Fix it by creating new function ip_vs_dest_put_and_free()
which is heavier than ip_vs_dest_put(). We will use it just
for schedulers like LBLC, LBLCR that can delay their dest
release.
By default, dests reference is above 0 if they are present in
service and it is 0 when deleted but still in trash list.
Change the dest trash code to use ip_vs_dest_put_and_free(),
so that refcnt -1 can be used for freeing. As result,
such checks remain in slow path and the rcu_barrier() from
netns cleanup can be removed.
