In commit b396966c4 (netfilter: xt_TCPMSS: Fix missing fragmentation handling),
I attempted to add safe fragment handling to xt_TCPMSS. However, Andy Padavan
of Project N56U correctly points out that returning XT_CONTINUE in this
function does not work. The callers (tcpmss_tg[46]) expect to receive a value
of 0 in order to return XT_CONTINUE.

Packets reaching SYNPROXY were default dropped, as they were most
likely invalid (given the recommended state matching). This
patch, changes SYNPROXY target to let packets, not consumed,
continue being processed by the stack.
This will be more in line other target modules. As it will allow
more flexible configurations of handling, logging or matching on
packets in INVALID states.

With CONFIG_NETFILTER_DEBUG we get the following warning during SYNPROXY init:
[ 80.558906] WARNING: CPU: 1 PID: 4833 at net/netfilter/nf_conntrack_extend.c:80 __nf_ct_ext_add_length+0x217/0x220 [nf_conntrack]()
The reason is that the conntrack template is set to confirmed before adding
the extension and it is invalid to add extensions to already confirmed
conntracks. Fix by adding the extensions before setting the conntrack to
confirmed.

Its seems Patrick missed to incoorporate some of my requested changes
during review v2 of SYNPROXY netfilter module.
Which were, to avoid SYN+ACK packets to enter the path, meant for the
ACK packet from the client (from the 3WHS).
Further there were a bug in ip6t_SYNPROXY.c, for matching SYN packets
that didn't exclude the ACK flag.
Go a step further with SYN packet/flag matching by excluding flags
ACK+FIN+RST, in both IPv4 and IPv6 modules.
The intented usage of SYNPROXY is as follows:
(gracefully describing usage in commit)
iptables -t raw -A PREROUTING -i eth0 -p tcp --dport 80 --syn -j NOTRACK
iptables -A INPUT -i eth0 -p tcp --dport 80 -m state UNTRACKED,INVALID \
-j SYNPROXY --sack-perm --timestamp --mss 1480 --wscale 7 --ecn
echo 0 > /proc/sys/net/netfilter/nf_conntrack_tcp_loose
This does filter SYN flags early, for packets in the UNTRACKED state,
but packets in the INVALID state with other TCP flags could still
reach the module, thus this stricter flag matching is still needed.

tcp_rcv_established() returns only one value namely 0. We change the return
value to void (as suggested by David Miller).
After commit 0c24604b (tcp: implement RFC 5961 4.2), we no longer send RSTs in
response to SYNs. We can remove the check and processing on the return value of
tcp_rcv_established().
We also fix jtcp_rcv_established() in tcp_probe.c to match that of
tcp_rcv_established().

With recent changes in tcp_probe module (e.g. f925d0a62d ("net: tcp_probe:
add IPv6 support")) we also need to take into account that tbuf needs to
be updated as format string will be further expanded. tbuf sits on the stack
in tcpprobe_read() function that is invoked when user space reads procfs
file /proc/net/tcpprobe, hence not fast path as in jtcp_rcv_established().
Having a size similarly as in sctp_probe module of 256 bytes is fully
sufficient for that, we need theoretical maximum of 252 bytes otherwise we
could get truncated.

RFC 4443 has defined two additional codes for ICMPv6 type 1 (destination
unreachable) messages:
5 - Source address failed ingress/egress policy
6 - Reject route to destination
Now they are treated as protocol error and icmpv6_err_convert() converts them
to EPROTO.
RFC 4443 says:
"Codes 5 and 6 are more informative subsets of code 1."
Treat codes 5 and 6 as code 1 (EACCES)
Btw, connect() returning -EPROTO confuses firefox, so that fallback to
other/IPv4 addresses does not work:

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
Please accept this batch of updates intended for the 3.12 stream.
For the mac80211 bits, Johannes says this:
"This time I have various improvements all over the place: IBSS, mesh,
testmode, AP client powersave handling, one of the rare rfkill patches
and some code cleanup."
Also for mac80211:
"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."
And for iwlwifi:
"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."
Regarding the Bluetooth bits, Gustavo says:
"Patches to 3.12, here we have:
* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"
For the NFC bits, Samuel says:
"With this one we have:
- A few pn533 improvements and minor fixes. Testing our pn533 driver
against Google's NCI stack triggered a few issues that we fixed now.
We also added Tx fragmentation support to this driver.
- More NFC secure element handling. We added a GET_SE netlink command
for getting all the discovered secure elements, and we defined 2
additional secure element netlink event (transaction and connectivity).
We also fixed a couple of typos and copy-paste bugs from the secure
element handling code.
- Firmware download support for the pn544 driver. This chipset can enter a
special mode where it's waiting for firmware blobs to replace the
already flashed one. We now support that mode."
With repect to the ath tree, Kalle says:
"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.
For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."
I also pulled the wireless tree into wireless-next to support a
request from Johannes. On top of all that, there are the usual
sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.

This config option is superfluous in that it only guards a call
to neigh_app_ns(). Enabling CONFIG_ARPD by default has no
change in behavior. There will now be call to __neigh_notify()
for each ARP resolution, which has no impact unless there is a
user space daemon waiting to receive the notification, i.e.,
the case for which CONFIG_ARPD was designed anyways.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
"A lot of activities on the cgroup front. Most changes aren't visible
to userland at all at this point and are laying foundation for the
planned unified hierarchy.
- The biggest change is decoupling the lifetime management of css
(cgroup_subsys_state) from that of cgroup's. Because controllers
(cpu, memory, block and so on) will need to be dynamically enabled
and disabled, css which is the association point between a cgroup
and a controller may come and go dynamically across the lifetime of
a cgroup. Till now, css's were created when the associated cgroup
was created and stayed till the cgroup got destroyed.
Assumptions around this tight coupling permeated through cgroup
core and controllers. These assumptions are gradually removed,
which consists bulk of patches, and css destruction path is
completely decoupled from cgroup destruction path. Note that
decoupling of creation path is relatively easy on top of these
changes and the patchset is pending for the next window.
- cgroup has its own event mechanism cgroup.event_control, which is
only used by memcg. It is overly complex trying to achieve high
flexibility whose benefits seem dubious at best. Going forward,
new events will simply generate file modified event and the
existing mechanism is being made specific to memcg. This pull
request contains prepatory patches for such change.
- Various fixes and cleanups"

This patch provides the RPC layer helper functions to allow NFS to manage
data in the face of expired credentials - such as avoiding buffered WRITEs
and COMMITs when the gss context will expire before the WRITEs are flushed
and COMMITs are sent.
These helper functions enable checking the expiration of an underlying
credential key for a generic rpc credential, e.g. the gss_cred gss context
gc_expiry which for Kerberos is set to the remaining TGT lifetime.
A new rpc_authops key_timeout is only defined for the generic auth.
A new rpc_credops crkey_to_expire is only defined for the generic cred.
A new rpc_credops crkey_timeout is only defined for the gss cred.
Set a credential key expiry watermark, RPC_KEY_EXPIRE_TIMEO set to 240 seconds
as a default and can be set via a module parameter as we need to ensure there
is time for any dirty data to be flushed.
If key_timeout is called on a credential with an underlying credential key that
will expire within watermark seconds, we set the RPC_CRED_KEY_EXPIRE_SOON
flag in the generic_cred acred so that the NFS layer can clean up prior to
key expiration.
Checking a generic credential's underlying credential involves a cred lookup.
To avoid this lookup in the normal case when the underlying credential has
a key that is valid (before the watermark), a notify flag is set in
the generic credential the first time the key_timeout is called. The
generic credential then stops checking the underlying credential key expiry, and
the underlying credential (gss_cred) match routine then checks the key
expiration upon each normal use and sets a flag in the associated generic
credential only when the key expiration is within the watermark.
This in turn signals the generic credential key_timeout to perform the extra
credential lookup thereafter.
