net: gro: allow to build full sized skb
skb_gro_receive() is currently limited to 16 or 17 MSS per GRO skb,
typically 24616 bytes, because it fills up to MAX_SKB_FRAGS frags.
It's relatively easy to extend the skb using frag_list to allow
more frags to be appended into the last sk_buff.
This still builds very efficient skbs, and allows reaching 45 MSS per
skb.
(45 MSS GRO packet uses one skb plus a frag_list containing 2 additional
sk_buff)
High speed TCP flows benefit from this extension by lowering TCP stack
cpu usage (less packets stored in receive queue, less ACK packets
processed)
Forwarding setups could be hurt, as such skbs will need to be
linearized, although its not a new problem, as GRO could already
provide skbs with a frag_list.
We could make the 65536 bytes threshold a tunable to mitigate this.
(First time we need to linearize skb in skb_needs_linearize(), we could
lower the tunable to ~16*1460 so that following skb_gro_receive() calls
build smaller skbs)

ipv6: make lookups simpler and faster
TCP listener refactoring, part 4 :
To speed up inet lookups, we moved IPv4 addresses from inet to struct
sock_common
Now is time to do the same for IPv6, because it permits us to have fast
lookups for all kind of sockets, including upcoming SYN_RECV.
Getting IPv6 addresses in TCP lookups currently requires two extra cache
lines, plus a dereference (and memory stall).
inet6_sk(sk) does the dereference of inet_sk(__sk)->pinet6
This patch is way bigger than its IPv4 counter part, because for IPv4,
we could add aliases (inet_daddr, inet_rcv_saddr), while on IPv6,
it's not doable easily.
inet6_sk(sk)->daddr becomes sk->sk_v6_daddr
inet6_sk(sk)->rcv_saddr becomes sk->sk_v6_rcv_saddr
And timewait socket also have tw->tw_v6_daddr & tw->tw_v6_rcv_saddr
at the same offset.

tcp/dccp: remove twchain
TCP listener refactoring, part 3 :
Our goal is to hash SYN_RECV sockets into main ehash for fast lookup,
and parallel SYN processing.
Current inet_ehash_bucket contains two chains, one for ESTABLISH (and
friend states) sockets, another for TIME_WAIT sockets only.
As the hash table is sized to get at most one socket per bucket, it
makes little sense to have separate twchain, as it makes the lookup
slightly more complicated, and doubles hash table memory usage.
If we make sure all socket types have the lookup keys at the same
offsets, we can use a generic and faster lookup. It turns out TIME_WAIT
and ESTABLISHED sockets already have common lookup fields for IPv4.
[ INET_TW_MATCH() is no longer needed ]
I'll provide a follow-up to factorize IPv6 lookup as well, to remove
INET6_TW_MATCH()
This way, SYN_RECV pseudo sockets will be supported the same.
A new sock_gen_put() helper is added, doing either a sock_put() or
inet_twsk_put() [ and will support SYN_RECV later ].
Note this helper should only be called in real slow path, when rcu
lookup found a socket that was moved to another identity (freed/reused
immediately), but could eventually be used in other contexts, like
sock_edemux()

For UDP multicast we can only cache the dst if there is only one

one receiving socket we do the multicast socket lookup using RCU.
For UDP unicast we only demux sockets with an exact match in order to
not break forwarding setups. Additionally since the hash chains may be

waste extra time searching the whole chain when we might not find an

and Joe Perches's "extern" removal from function prototypes
in header files.
John W. Linville says:
====================
Regarding the Bluetooth bits, Gustavo says:
"The big work here is from Marcel and Johan. They did a lot of work
in the L2CAP, HCI and MGMT layers. The most important ones are the
addition of a new MGMT command to enable/disable LE advertisement
and the introduction of the HCI user channel to allow applications
to get directly and exclusive access to Bluetooth devices."
As to the ath10k bits, Kalle says:
"Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's
just too much to support it. Michal added support for the new firmware
interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are
minor fixes or cleanups."
And also:
"Major changes are:
* throughput improvements including aligning the RX frames correctly and
optimising HTT layer (Michal)
* remove qca98xx hw1.0 support (Bartosz)
* add support for firmware version 999.999.0.636 (Michal)
* firmware htt statistics support (Kalle)
* fix WEP in AP and IBSS mode (Marek)
* fix a mutex unlock balance in debugfs file (Shafi)
And of course there's a lot of smaller fixes and cleanup."
For the wl12xx bits, Luca says:
"Here are some patches intended for 3.13. Eliad is upstreaming a bunch
of patches that have been pending in the internal tree. Mostly bugfixes
and other small improvements."
Along with that...
Arend and friends bring us a batch of brcmfmac updates, Larry Finger
offers some rtlwifi refactoring, and Sujith sends the usual batch of
ath9k updates. As usual, there are a number of other small updates
from a variety of players as well.

However, there should be no IPv6 on the tunnel interface at all, so the IPv6 rules should not apply.

The following patchset contains Netfilter updates for your net-next tree,
mostly ipset improvements and enhancements features, they are:
* Don't call ip_nest_end needlessly in the error path from me, suggested
by Pablo Neira Ayuso, from Jozsef Kadlecsik.
* Fixed sparse warnings about shadowed variable and missing rcu annotation
and fix of "may be used uninitialized" warnings, also from Jozsef.
* Renamed simple macro names to avoid namespace issues, reported by David
Laight, again from Jozsef.
* Use fix sized type for timeout in the extension part, and cosmetic
ordering of matches and targets separatedly in xt_set.c, from Jozsef.
* Support package fragments for IPv4 protos without ports from Anders K.
Pedersen. For example this allows a hash:ip,port ipset containing the
entry 192.168.0.1,gre:0 to match all package fragments for PPTP VPN
tunnels to/from the host. Without this patch only the first package
fragment (with fragment offset 0) was matched.
* Introduced a new operation to get both setname and family, from Jozsef.
ip[6]tables set match and SET target need to know the family of the set
in order to reject adding rules which refer to a set with a non-mathcing
family. Currently such rules are silently accepted and then ignored
instead of generating an error message to the user.
* Reworked extensions support in ipset types from Jozsef. The approach of
defining structures with all variations is not manageable as the
number of extensions grows. Therefore a blob for the extensions is
introduced, somewhat similar to conntrack. The support of extensions
which need a per data destroy function is added as well.
* When an element timed out in a list:set type of set, the garbage
collector skipped the checking of the next element. So the purging
was delayed to the next run of the gc, fixed by Jozsef.
* A small Kconfig fix: NETFILTER_NETLINK cannot be selected and
ipset requires it.
* hash:net,net type from Oliver Smith. The type provides the ability to
store pairs of subnets in a set.
* Comment for ipset entries from Oliver Smith. This makes possible to
annotate entries in a set with comments, for example:
ipset n foo hash:net,net comment
ipset a foo 10.0.0.0/21,192.168.1.0/24 comment "office nets A and B"
* Fix of hash types resizing with comment extension from Jozsef.
* Fix of new extensions for list:set type when an element is added
into a slot from where another element was pushed away from Jozsef.
* Introduction of a common function for the listing of the element
extensions from Jozsef.
* Net namespace support for ipset from Vitaly Lavrov.
* hash:net,port,net type from Oliver Smith, which makes possible
to store the triples of two subnets and a protocol, port pair in
a set.
* Get xt_TCPMSS working with net namespace, by Gao feng.
* Use the proper net netnamespace to allocate skbs, also by Gao feng.
* A couple of cleanups for the conntrack SIP helper, by Holger
Eitzenberger.
* Extend cttimeout to allow setting default conntrack timeouts via
nfnetlink, so we can get rid of all our sysctl/proc interfaces in
the future for timeout tuning, from me.

tcp: shrink tcp6_timewait_sock by one cache line
While working on tcp listener refactoring, I found that it
would really make things easier if sock_common could include
the IPv6 addresses needed in the lookups, instead of doing
very complex games to get their values (depending on sock
being SYN_RECV, ESTABLISHED, TIME_WAIT)
For this to happen, I need to be sure that tcp6_timewait_sock
and tcp_timewait_sock consume same number of cache lines.
This is possible if we only use 32bits for tw_ttd, as we remove
one 32bit hole in inet_timewait_sock
inet_tw_time_stamp() is defined and used, even if its current
implementation looks like tcp_time_stamp : We might need finer
resolution for tcp_time_stamp in the future.
Before patch : sizeof(struct tcp6_timewait_sock) = 0xc8
After patch : sizeof(struct tcp6_timewait_sock) = 0xc0

atl1e: enable support for NETIF_F_RXALL and NETIF_F_RXCRC features
This patch allows (optionally, via ethtool) the atl1e NIC to:
- Receive bad frames (runt, bad-fcs, etc..)
- Receive full frames without stripping the FCS.
This has been tested on my board by injecting runt and bad-fcs
frames with a FPGA-based device.
The particular scenario of receiving very short frames (<4 bytes)
without passing FCS to the upper layer has been also tested:
This could be potentially dangerous because the driver performs a
4 byte subtraction on the frame length, but I finally have NOT
added anything to avoid this because it seems the NIC always
discards frames so much short..
If someone still have some reason to worry about this, please
tell me.. I will add an explicit SW check..

net: heap overflow in __audit_sockaddr()
We need to cap ->msg_namelen or it leads to a buffer overflow when we
to the memcpy() in __audit_sockaddr(). It requires CAP_AUDIT_CONTROL to
exploit this bug.
The call tree is:
___sys_recvmsg()
move_addr_to_user()
audit_sockaddr()
__audit_sockaddr()

3com: Fix drivers/net/ethernet/3com/Kconfig references to PCMCIA and 3c515
The Vortex driver works with PCI and Cardbus devices, not PCMCIA.
There never was an EISA 3c515 card, only ISA, so remove that option.
