git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz <sameo@linux.intel.com> says:
"With this one we have:
- One patch for moving the LLCP code into net/nfc.
It fixes a build annoyance reported by Dave Miller caused by the fact
that the LLCP code object targets are not in the same directory as the
Makefile trying to build them is. It prevents us from doing e.g.
make net/nfc/llcp/sock.o
Moving the LLCP code into net/nfc and not making it optional anymore
makes sense as LLCP is a fundamental piece of the NFC specifications
and thus should be in the core NFC directory.
- One patch that fixes the missing dependency against RFKILL. Without it NFC
fails to properly build when it's builtin and CONFIG_RFKILL=m."

Since the NFC subsystem gained RFKILL support, it needs to be able
to build properly with whatever option for RFKILL has been selected.

and hence there is no need to kfree the current command buffer
again. This might ends up freeing memory allocated by some other

first_antenna is supposed to return the first antenna as a
0-based bitmap: ANT_A is BIT(0), ANT_B is BIT(1), etc...
Since ffs is 1 based (ffs(BIT(0)) = 1), then we had an
off-by-one bug:
BIT(ffs(ANT_A)) = BIT(ffs(BIT(0))) = BIT(1) = ANT_B.
So what we really want is:
BIT(ffs(ANT_A) - 1) = BIT(ffs(BIT(0)) - 1) = BIT(0) = ANT_A.

FW does the synchronization of the different modules during init.
It will report different modules, that it is ready at different times.
The fw download 'winner' will be reported fw ready first. Without this
patch, btmrvl was already continuing before the FW told it too. Probably
on behalf of the 'winner' which then never sees FW ready and times out.

The Bluetooth Core Specification (4.0) defines the Write LE Host
Supported HCI command as only available for controllers supporting
BR/EDR. This is further reflected in the Read Local Extended Features
HCI command also not being available for LE-only controllers. In other
words, host-side LE support is implicit for single-mode LE controllers
and doesn't have explicit HCI-level enablement.
This patch ensures that the LE setting is always exposed as enabled
through mgmt and returns a "rejected" response if user space tries to
toggle the setting. The patch also ensures that Write LE Host Supported
is never sent for LE-only controllers.

All HCI command send functions that take a pointer to the command
parameters do not need to modify the content in any way (they merely
copy the data to an skb). Therefore, the parameter type should be
declared const. This also allows passing already const parameters to
these APIs which previously would have generated a compiler warning.

Newer firmware can post CPL_SGE_EGR_UPDATE message encapsulated in a
CPL_FW4_MSG as follows
flit0 rss_header (if DropRSS == 0 in IQ context)
flit1 CPL_FW4_MSG cpl
flit2 rss_header w/opcode CPL_SGE_EGR_UPDATE
flit3 CPL_SGE_EGR_UPDATE cpl
So FW4_MSG CPLs with a newly created type of FW_TYPE_RSSCPL have the
CPL_SGE_EGR_UPDATE CPL message in flit 2 of the FW4_MSG. Firmware can still
post regular CPL_SGE_EGR_UPDATE messages, so the drivers need to handle
both.
This patch also writes a new parameter to firmware requesting encapsulated
EGR_UPDATE. This allows firmware with this support to not break older drivers.

Linux immediately returns SYNACK on (spurious) SYN retransmits, but
keeps the SYNACK timer running independently. Thus the timer may
fire right after the SYNACK retransmit and causes a SYN-SYNACK
cross-fire burst.
Adopt the fast retransmit/recovery idea in established state by
re-arming the SYNACK timer after the fast (SYNACK) retransmit. The
timer may fire late up to 500ms due to the current SYNACK timer wheel,
but it's OK to be conservative when network is congested. Eric's new
listener design should address this issue.

Pablo Neira Ayuso says:
====================
The following patchset contains relevant updates for the Netfilter
tree, they are:
* Enhancements for ipset: Add the counter extension for sets, this
information can be used from the iptables set match, to change
the matching behaviour. Jozsef required to add the extension
infrastructure and moved the existing timeout support upon it.
This also includes a change in net/sched/em_ipset to adapt it to
the new extension structure.
* Enhancements for performance boosting in nfnetlink_queue: Add new
configuration flags that allows user-space to receive big packets (GRO)
and to disable checksumming calculation. This were proposed by Eric
Dumazet during the Netfilter Workshop 2013 in Copenhagen. Florian
Westphal was kind enough to find the time to materialize the proposal.
* A sparse fix from Simon, he noticed it in the SCTP NAT helper, the fix
required a change in the interface of sctp_end_cksum.

Change the type of the crc32 parameter of sctp_end_cksum()
from __be32 to __u32 to reflect that fact that it is passed
to cpu_to_le32().
There are five in-tree users of sctp_end_cksum().
The following four had warnings flagged by sparse which are
no longer present with this change.
net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_nat_csum()
net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_csum_check()
net/sctp/input.c:sctp_rcv_checksum()
net/sctp/output.c:sctp_packet_transmit()
The fifth user is net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt().
It has been updated to pass a __u32 instead of a __be32,
the value in question was already calculated in cpu byte-order.
net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt() has also
been updated to assign the return value of sctp_end_cksum()
directly to a variable of type __le32, matching the
type of the return value. Previously the return value
was assigned to a variable of type __be32 and then that variable
was finally assigned to another variable of type __le32.
Problems flagged by sparse.
Compile and sparse tested only.

Once we allow userspace to receive gso/gro packets, userspace
needs to be able to determine when checksums appear to be
broken, but are not.
NFQA_SKB_CSUMNOTREADY means 'checksums will be fixed in kernel
later, pretend they are ok'.
NFQA_SKB_GSO could be used for statistics, or to determine when
packet size exceeds mtu.

skb_gso_segment is expensive, so it would be nice if we could
avoid it in the future. However, userspace needs to be prepared
to receive larger-than-mtu-packets (which will also have incorrect
l3/l4 checksums), so we cannot simply remove it.
The plan is to add a per-queue feature flag that userspace can
set when binding the queue.
The problem is that in nf_queue, we only have a queue number,
not the queue context/configuration settings.
This patch should have no impact other than the skb_gso_segment
call now being in a function that has access to the queue config
data.
A new size attribute in nf_queue_entry is needed so
nfnetlink_queue can duplicate the entry of the gso skb
when segmenting the skb while also copying the route key.
The follow up patch adds switch to disable skb_gso_segment when
queue config says so.
