6364853dab 9p: disallow RDMA if RDMA CM isn't available
If INET=y and INFINIBAND=y, but IPV6=m then INFINIBAND_ADDR_TRANS is set
to n and the RDMA CM functions rdma_connect() et al are not built.
However, the current config dependencies allow NET_9P_RDMA to be selected
in this, which leads to a build failure.  Fix this by adding a dependency
on INFINIBAND_ADDR_TRANS to disallow NET_9P_RDMA in this case.

c53a6ee88b can: fix slowpath issue in hrtimer callback function
Due to the loopback functionality in can_send() we can not invoke it
from hardirq context which was done inside the

937f1ba56b net: Add init_dummy_netdev() and fix EMAC driver using it
This adds an init_dummy_netdev() function that gets a network device
structure (allocation and lifetime entirely under caller's control) and
initialize the minimum amount of fields so it can be used to schedule
NAPI polls without registering a full blown interface. This is to be
used by drivers that need to tie several hardware interfaces to a single
NAPI poll scheduler due to HW limitations.

It also updates the ibm_newemac driver to use that, this fixing the
oops on 2.6.29 due to passing NULL as "dev" to netif_napi_add()

Symbol is exported GPL only a I don't think we want binary drivers doing
that sort of acrobatics (if we want them at all).

f557206800 gro: Fix page ref count for skbs freed normally
When an skb with page frags is merged into an existing one, we
cannibalise its reference count.  This is OK when the skb is
reused because we set nr_frags to zero in that case.  However,
for the case where the skb is freed through kfree_skb, we didn't
clear nr_frags which causes the page to be freed prematurely.

This is fixed by moving the skb resetting into skb_gro_receive.

f17f5c91ae gro: Check for GSO packets and packets with frag_list
As GRO cannot be applied to packets with frag_list we need to
make sure that we reject such packets if they are fed to us,
e.g., through a tunnel device.

Also there is no point in applying GRO on GSO packets so they
too should be rejected.  This allows GRO to be used in virtio-net
which may produce GSO packets directly but may still benefit
from GRO if the other end of it doesn't support GSO.

33966dd0e2 tcp: splice as many packets as possible at once
As spotted by Willy Tarreau, current splice() from tcp socket to pipe is not
optimal. It processes at most one segment per call.
This results in low performance and very high overhead due to syscall rate
when splicing from interfaces which do not support LRO.

Willy provided a patch inside tcp_splice_read(), but a better fix
is to let tcp_read_sock() process as many segments as possible, so
that tcp_rcv_space_adjust() and tcp_cleanup_rbuf() are called less
often.

With this change, splice() behaves like tcp_recvmsg(), being able
to consume many skbs in one system call. With typical 1460 bytes
of payload per frame, that means splice(SPLICE_F_NONBLOCK) can return
16*1460 = 23360 bytes.

cd7fcbf1cb netfilter 07/09: simplify nf_conntrack_alloc() error handling
nf_conntrack_alloc cannot return NULL, so there is no need to check for
NULL before using the value.  I have also removed the initialization of ct
to NULL in nf_conntrack_alloc, since the value is never used, and since
perhaps it might lead one to think that return ct at the end might return
NULL.

47e0e1ca13 netfilter 03/09: bridge: Disable PPPOE/VLAN processing by default
The PPPOE/VLAN processing code in the bridge netfilter is broken
by design.  The VLAN tag and the PPPOE session ID are an integral
part of the packet flow information, yet they're completely
ignored by the bridge netfilter.  This is potentially a security
hole as it treats all VLANs and PPPOE sessions as the same.

What's more, it's actually broken for PPPOE as the bridge netfilter
tries to trim the packets to the IP length without adjusting the
PPPOE header (and adjusting the PPPOE header isn't much better
since the PPPOE peer may require the padding to be present).

Therefore we should disable this by default.

It does mean that people relying on this feature may lose networking
depending on how their bridge netfilter rules are configured.
However, IMHO the problems this code causes are serious enough to
warrant this.

Therefore rate_lowest_index returns 4 (= 6Mbit, instead of usual 0 = 1Mbit).
Since mi->r array is initialized with zeros in minstrel_alloc_sta,
rix_to_ndx has a hard time to find the 6Mbit entry and will trigged the WARNING.

This bug is not related to the truesize warnings since we only
made it bigger than what it should've been.

a2e9da4b09 wimax: testing for rfkill support should also test for CONFIG_RFKILL_MODULE
Current WiMAX rfkill code is missing the case where rfkill is compiled
in as modules and works only when rfkill is compiled in. This is not
correct. Fixed to test for CONFIG_RFKILL or CONFIG_RKILL_MODULE.

71f78afd67 wimax: fix kconfig interactions with rfkill and input layers
WiMAX can work without RFKILL, but it was missing a check to make sure
RFKILL is not being made a module with wimax compiled into the
kernel. This caused failed builds in s390, where CONFIG_INPUT is
always off.

When RFKILL is enabled, the code uses the input layer to report
hardware switch changes; thus, if RFKILL is enabled, INPUT has to be
too. It also needs to display some message when INPUT is disabled that
explains why WiMAX is not selectable.

(issues found by Randy Dunlap in the linux-next tree).

d48e470f76 wimax: fix '#ifndef CONFIG_BUG' layout to avoid warning
Reported by Randy Dunlap:

> Also, this warning needs to be fixed:
>
> linux-next-20090106/net/wimax/id-table.c:133: warning: ISO C90
> forbids mixed declarations and code

Move the return on #defined(CONFIG_BUG) below the variable
declarations so it doesn't violate ISO C90.

On wimax_id_table_release() we want to do a debug check if CONFIG_BUG
is enabled. However, we also want the debug code to be always compiled
to ensure there is no bitrot. It will be optimized out by the compiler
when CONFIG_BUG is disabled.

Added a note to the function header stating this.

684f217601 tcp6: Add GRO support
This patch adds GRO support for TCP over IPv6.  The code is exactly
the same as the IPv4 version except for the pseudo-header checksum
computation.

Note that I've removed the unused tcphdr argument from tcp_v6_check
rather than invent a bogus value for GRO.

787e920836 ipv6: Add GRO support
This patch adds GRO support for IPv6.  IPv6 GRO supports extension
headers in the same way as GSO (by using the same infrastructure).
It's also simpler compared to IPv4 since we no longer have to worry
about fragmentation attributes or header checksums.
