The maximum size of ATR_REQ and ATR_RES is 64 bytes.
The maximum number of General Bytes is calculated by
the maximum number of data bytes in the ATR_REQ/ATR_RES,
substracted by the number of mandatory data bytes.
ATR_REQ: 16 mandatory data bytes, giving a maximum of
48 General Bytes.
ATR_RES: 17 mandatory data bytes, giving a maximum of
47 General Bytes.
Regression introduced in commit a99903ec.

Some tag might get deactivated after some read or write tentative.
This may happen for example with Mifare Ultralight C tag when trying
to read the last 4 blocks (starting block 0x2c) configured as write
only.
NFC_CMD_ACTIVATE_TARGET will try to reselect the tag in order to
detect if it got remove from the field or if it is still present.

The commit [7a2e9ddc: ALSA: usb-audio: Add native DSD support for
Denon/Marantz DACs] requires the new format definition that has
landed only in for-next branch.
|

Changes:
* Extract the Listen mode activation parameters from RF_INTF_ACTIVATED_NTF.
* Store the General Bytes of ATR_REQ.
* Signal that Target mode is activated in case of an activation in NFC-DEP.
* Update the NCI state accordingly.
* Use the various constants defined in nfc.h.
* Fix the ATR_REQ and ATR_RES maximum size. As per NCI 1.0 and NCI 1.1, the
Activation Parameters for both Poll and Listen mode contain all the bytes of
ATR_REQ/ATR_RES starting and including Byte 3 as defined in [DIGITAL].
In [DIGITAL], the maximum size of ATR_REQ/ATR_RES is 64 bytes and they are
numbered starting from Byte 1.

This regeset is intended to be used to get and set a system call number
while tracing.
There was some discussion about possible approaches to do so:
(1) modify x8 register with ptrace(PTRACE_SETREGSET) indirectly,
and update regs->syscallno later on in syscall_trace_enter(), or
(2) define a dedicated regset for this purpose as on s390, or
(3) support ptrace(PTRACE_SET_SYSCALL) as on arch/arm
Thinking of the fact that user_pt_regs doesn't expose 'syscallno' to
tracer as well as that secure_computing() expects a changed syscall number,
especially case of -1, to be visible before this function returns in
syscall_trace_enter(), (1) doesn't work well.
We will take (2) since it looks much cleaner.

====================
netfilter/ipvs updates for net-next
The following patchset contains Netfilter updates for your net-next
tree, this includes the NAT redirection support for nf_tables, the
cgroup support for nft meta and conntrack zone support for the connlimit
match. Coming after those, a bunch of sparse warning fixes, missing
netns bits and cleanups. More specifically, they are:
1) Prepare IPv4 and IPv6 NAT redirect code to use it from nf_tables,
patches from Arturo Borrero.
2) Introduce the nf_tables redir expression, from Arturo Borrero.
3) Remove an unnecessary assignment in ip_vs_xmit/__ip_vs_get_out_rt().
Patch from Alex Gartrell.
4) Add nft_log_dereference() macro to the nf_log infrastructure, patch
from Marcelo Leitner.
5) Add some extra validation when registering logger families, also
from Marcelo.
6) Some spelling cleanups from stephen hemminger.
7) Fix sparse warning in nf_logger_find_get().
8) Add cgroup support to nf_tables meta, patch from Ana Rey.
9) A Kconfig fix for the new redir expression and fix sparse warnings in
the new redir expression.
10) Fix several sparse warnings in the netfilter tree, from
Florian Westphal.
11) Reduce verbosity when OOM in nfnetlink_log. User can basically do
nothing when this situation occurs.
12) Add conntrack zone support to xt_connlimit, again from Florian.
13) Add netnamespace support to the h323 conntrack helper, contributed
by Vasily Averin.
14) Remove unnecessary nul-pointer checks before free_percpu() and
module_put(), from Markus Elfring.
15) Use pr_fmt in nfnetlink_log, again patch from Marcelo Leitner.

This driver is very similar to the macvlan driver except that it
uses L3 on the frame to determine the logical interface while
functioning as packet dispatcher. It inherits L2 of the master
device hence the packets on wire will have the same L2 for all
the packets originating from all virtual devices off of the same
master device.
This driver was developed keeping the namespace use-case in
mind. Hence most of the examples given here take that as the
base setup where main-device belongs to the default-ns and
virtual devices are assigned to the additional namespaces.
The device operates in two different modes and the difference
in these two modes in primarily in the TX side.
(a) L2 mode : In this mode, the device behaves as a L2 device.
TX processing upto L2 happens on the stack of the virtual device
associated with (namespace). Packets are switched after that
into the main device (default-ns) and queued for xmit.
RX processing is simple and all multicast, broadcast (if
applicable), and unicast belonging to the address(es) are
delivered to the virtual devices.
(b) L3 mode : In this mode, the device behaves like a L3 device.
TX processing upto L3 happens on the stack of the virtual device
associated with (namespace). Packets are switched to the
main-device (default-ns) for the L2 processing. Hence the routing
table of the default-ns will be used in this mode.
RX processins is somewhat similar to the L2 mode except that in
this mode only Unicast packets are delivered to the virtual device
while main-dev will handle all other packets.
The devices can be added using the "ip" command from the iproute2
package -
ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ]

John W. Linville says:
====================
pull request: wireless-next 2014-11-21
Please pull this batch of updates intended for the 3.19 stream...
For the mac80211 bits, Johannes says:
"It has been a while since my last pull request, so we accumulated
another relatively large set of changes:
* TDLS off-channel support set from Arik/Liad, with some support
patches I did
* custom regulatory fixes from Arik
* minstrel VHT fix (and a small optimisation) from Felix
* add back radiotap vendor namespace support (myself)
* random MAC address scanning for cfg80211/mac80211/hwsim (myself)
* CSA improvements (Luca)
* WoWLAN Net Detect (wake on network found) support (Luca)
* and lots of other smaller changes from many people"
For the Bluetooth bits, Johan says:
"Here's another set of patches for 3.19. Most of it is again fixes and
cleanups to ieee802154 related code from Alexander Aring. We've also got
better handling of hardware error events along with a proper API for HCI
drivers to notify the HCI core of such situations. There's also a minor
fix for mgmt events as well as a sparse warning fix. The code for
sending HCI commands synchronously also gets a fix where we might loose
the completion event in the case of very fast HW (particularly easily
reproducible with an emulated HCI device)."
And...
"Here's another bluetooth-next pull request for 3.19. We've got:
- Various fixes, cleanups and improvements to ieee802154/mac802154
- Support for a Broadcom BCM20702A1 variant
- Lots of lockdep fixes
- Fixed handling of LE CoC errors that should trigger SMP"
For the Atheros bits, Kalle says:
"One ath6kl patch and rest for ath10k, but nothing really major which
stands out. Most notable:
o fix resume (Bartosz)
o firmware restart is now faster and more reliable (Michal)
o it's now possible to test hardware restart functionality without
crashing the firmware using hw-restart parameter with
simulate_fw_crash debugfs file (Michal)"
On top of that...both ath9k and mwifiex get their usual level of
updates. Of note is the ath9k spectral scan work from Oleksij Rempel.
I also pulled from the wireless tree in order to avoid some merge issues.
Please let me know if there are problems!

A new netlink API for tipc that can disable or enable a tipc bearer.
The new API is separated from the old API because of a bug in the
user space client (tipc-config). The problem is that older versions
of tipc-config has a very low receive limit and adding commands to
the legacy genl_opts struct causes the ctrl_getfamily() response
message to grow, subsequently breaking the tool.
The new API utilizes netlink policies for input validation. Where the
top-level netlink attributes are tipc-logical entities, like bearer.
The top level entities then contain nested attributes. In this case
a name, nested link properties and a domain.
Netlink commands implemented in this patch:
TIPC_NL_BEARER_ENABLE
TIPC_NL_BEARER_DISABLE
Netlink logical layout of bearer enable message:
-> bearer

KVM ia64 is no longer present so new applications shouldn't use them.
The main problem is that they most likely didn't work even before,
because of a conflict in the #defines:
#define KVM_SET_GUEST_DEBUG _IOW(KVMIO, 0x9b, struct kvm_guest_debug)
#define KVM_IA64_VCPU_SET_STACK _IOW(KVMIO, 0x9b, void *)
The argument to KVM_SET_GUEST_DEBUG is:
struct kvm_guest_debug {
__u32 control;
__u32 pad;
struct kvm_guest_debug_arch arch;
};
struct kvm_guest_debug_arch {
};
meaning that sizeof(struct kvm_guest_debug) == sizeof(void *) == 8
and KVM_SET_GUEST_DEBUG == KVM_IA64_VCPU_SET_STACK.
KVM_SET_GUEST_DEBUG is handled in virt/kvm/kvm_main.c before even calling
kvm_arch_vcpu_ioctl (which would have handled KVM_IA64_VCPU_SET_STACK),
so KVM_IA64_VCPU_SET_STACK would just return -EINVAL.

I guess for hysterical raisins this was meant to be the way to read
blob properties. But that's done with the two-stage approach which
uses separate blob kms object and the special-purpose get_blob ioctl.
Shipping userspace seems to have never relied on this, and the kernel
also never put any blob thing onto that property. And nowadays it
would blow up, e.g. in drm_property_destroy. Also it makes no sense to
return values in an ioctl that only returns metadata about everything.
So let's ditch all the internal code for the blob list, rename the
list to be unambiguous and sprinkle comments all over the place to
explain this peculiar piece of api.

A process may exit, leaving an orphan lock in the lockspace.
This adds the capability for another process to acquire the
orphan lock. Acquiring the orphan just moves the lock from
the orphan list onto the acquiring process's list of locks.
An adopting process must specify the resource name and mode
of the lock it wants to adopt. If a matching lock is found,
the lock is moved to the caller's 's list of locks, and the
lkid of the lock is returned like the lkid of a new lock.
If an orphan with a different mode is found, then -EAGAIN is
returned. If no orphan lock is found on the resource, then
-ENOENT is returned. No async completion is used because
the result is immediately available.
Also, when orphans are purged, allow a zero nodeid to refer
to the local nodeid so the caller does not need to look up
the local nodeid.

Add the necessary feature flags and a scan flag to support using
random MAC addresses for scan while unassociated.
The configuration for this supports an arbitrary MAC address
value and mask, so that any kind of configuration (e.g. fixed
OUI or full 46-bit random) can be requested. Full 46-bit random
is the default when no other configuration is passed.
Also add a small helper function to use the addr/mask correctly.

Add a new WoWLAN API to enable net-detect as a wake up trigger.
Net-detect allows the device to scan in the background while the
host is asleep to wake up the host system when a matching network
is found.
Reuse the scheduled scan attributes to specify how the scan is
performed while suspended and the matches that will trigger a
wake event.

Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.
Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

Define some related TDLS protocol constants and advertise channel switch
support in the extended-capabilities IE when the feature bit is defined.
Actually supporting TDLS channel-switching also requires support for
some new nl80211 commands, to be introduced by future patches.

Rename dm_internal_{suspend,resume} to dm_internal_{suspend,resume}_fast
-- dm-stats will continue using these methods to avoid all the extra
suspend/resume logic that is not needed in order to quickly flush IO.
Introduce dm_internal_suspend_noflush() variant that actually calls the
mapped_device's target callbacks -- otherwise target-specific hooks are
avoided (e.g. dm-thin's thin_presuspend and thin_postsuspend). Common
code between dm_internal_{suspend_noflush,resume} and
dm_{suspend,resume} was factored out as __dm_{suspend,resume}.
Update dm_internal_{suspend_noflush,resume} to always take and release
the mapped_device's suspend_lock. Also update dm_{suspend,resume} to be
aware of potential for DM_INTERNAL_SUSPEND_FLAG to be set and respond
accordingly by interruptibly waiting for the DM_INTERNAL_SUSPEND_FLAG to
be cleared. Add lockdep annotation to dm_suspend() and dm_resume().
The existing DM_SUSPEND_FLAG remains unchanged.
DM_INTERNAL_SUSPEND_FLAG is set by dm_internal_suspend_noflush() and
cleared by dm_internal_resume().
Both DM_SUSPEND_FLAG and DM_INTERNAL_SUSPEND_FLAG may be set if a device
was already suspended when dm_internal_suspend_noflush() was called --
this can be thought of as a "nested suspend". A "nested suspend" can
occur with legacy userspace dm-thin code that might suspend all active
thin volumes before suspending the pool for resize.
But otherwise, in the normal dm-thin-pool suspend case moving forward:
the thin-pool will have DM_SUSPEND_FLAG set and all active thins from
that thin-pool will have DM_INTERNAL_SUSPEND_FLAG set.
Also add DM_INTERNAL_SUSPEND_FLAG to status report. This new
DM_INTERNAL_SUSPEND_FLAG state is being reported to assist with
debugging (e.g. 'dmsetup info' will report an internally suspended
device accordingly).

So with all the code movement and extraction in intel_pm.c in -next
git is hopelessly confused with

drm/i915: drop WaSetupGtModeTdRowDispatch:snb
from -fixes. Worse even small changes in -next move around the
conflict context so rerere is equally useless. Let's just backmerge
and be done with it.
Conflicts:
drivers/gpu/drm/i915/i915_drv.c
drivers/gpu/drm/i915/intel_pm.c
Except for git getting lost no tricky conflicts really.
