2013-08-28netfilter: add SYNPROXY core/targetPatrick McHardy
Add a SYNPROXY for netfilter. The code is split into two parts, the synproxy core with common functions and an address family specific target. The SYNPROXY receives the connection request from the client, responds with a SYN/ACK containing a SYN cookie and announcing a zero window and checks whether the final ACK from the client contains a valid cookie. It then establishes a connection to the original destination and, if successful, sends a window update to the client with the window size announced by the server. Support for timestamps, SACK, window scaling and MSS options can be statically configured as target parameters if the features of the server are known. If timestamps are used, the timestamp value sent back to the client in the SYN/ACK will be different from the real timestamp of the server. In order to now break PAWS, the timestamps are translated in the direction server->client.

2013-08-28netfilter: nf_conntrack: make sequence number adjustments usuable without NATPatrick McHardy
Split out sequence number adjustments from NAT and move them to the conntrack core to make them usable for SYN proxying. The sequence number adjustment information is moved to a seperate extend. The extend is added to new conntracks when a NAT mapping is set up for a connection using a helper. As a side effect, this saves 24 bytes per connection with NAT in the common case that a connection does not have a helper assigned.

2013-08-28netfilter: ip[6]t_REJECT: tcp-reset using wrong MAC source if bridgedPhil Oester
As reported by Casper Gripenberg, in a bridged setup, using ip[6]t_REJECT with the tcp-reset option sends out reset packets with the src MAC address of the local bridge interface, instead of the MAC address of the intended destination. This causes some routers/firewalls to drop the reset packet as it appears to be spoofed. Fix this by bypassing ip[6]_local_out and setting the MAC of the sender in the tcp reset packet. This closes netfilter bugzilla #531. Signed-off-by: Phil Oester <kernel@linuxace.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2013-08-27VMXNET3: Add support for virtual IOMMUAndy King
This patch adds support for virtual IOMMU to the vmxnet3 module. We switch to DMA consistent mappings for anything we pass to the device. There were a few places where we already did this, but using pci_blah(); these have been fixed to use dma_blah(), along with all new occurrences where we've replaced kmalloc() and friends.

2013-08-27be2net: Fix be_cmd_if_create() to use MBOX if MCCQ is not createdSathya Perla
Currently the IF_CREATE FW cmd is issued only *after* MCCQ is created as it was coded to only use MCCQ. By fixing this, cmd_if_create() can be called before MCCQ is created and the same routine for VF provisioning can be called after. This allows for consolidating all the queue create routines by moving the be_cmd_if_create() call above all queue create calls in be_setup().

2013-08-27net: tcp_probe: allow more advanced ingress filtering by markDaniel Borkmann
Currently, the tcp_probe snooper can either filter packets by a given port (handed to the module via module parameter e.g. port=80) or lets all TCP traffic pass (port=0, default). When a port is specified, the port number is tested against the sk's source/destination port. Thus, if one of them matches, the information will be further processed for the log. As this is quite limited, allow for more advanced filtering possibilities which can facilitate debugging/analysis with the help of the tcp_probe snooper. Therefore, similarly as added to BPF machine in commit 7e75f93e ("pkt_sched: ingress socket filter by mark"), add the possibility to use skb->mark as a filter. If the mark is not being used otherwise, this allows ingress filtering by flow (e.g. in order to track updates from only a single flow, or a subset of all flows for a given port) and other things such as dynamic logging and reconfiguration without removing/re-inserting the tcp_probe module, etc. Simple example: insmod net/ipv4/tcp_probe.ko fwmark=8888 full=1 ... iptables -A INPUT -i eth4 -t mangle -p tcp --dport 22 \ --sport 60952 -j MARK --set-mark 8888 [... sampling interval ...] iptables -D INPUT -i eth4 -t mangle -p tcp --dport 22 \ --sport 60952 -j MARK --set-mark 8888 The current option to filter by a given port is still being preserved. A similar approach could be done for the sctp_probe module as a follow-up. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-08-23drivers/platform/olpc/olpc-ec.c: initialise earlierDaniel Drake
Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5a ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake <dsd@laptop.org> Cc: Andres Salomon <dilinger@queued.net> Cc: Paul Fox <pgf@laptop.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2013-08-22net: tcp_probe: add IPv6 supportDaniel Borkmann
The tcp_probe currently only supports analysis of IPv4 connections. Therefore, it would be nice to have IPv6 supported as well. Since we have the recently added %pISpc specifier that is IPv4/IPv6 generic, build related sockaddress structures from the flow information and pass this to our format string. Tested with SSH and HTTP sessions on IPv4 and IPv6. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-22net: tcp_probe: kprobes: adapt jtcp_rcv_established signatureDaniel Borkmann
This patches fixes a rather unproblematic function signature mismatch as the const specifier was missing for the th variable; and next to that it adds a build-time assertion so that future function signature mismatches for kprobes will not end badly, similarly as commit 22222997 ("net: sctp: add build check for sctp_sf_eat_sack_6_2/jsctp_sf_eat_sack") did it for SCTP.

2013-08-22net: tcp_probe: also include rcv_wnd next to snd_wndDaniel Borkmann
It is helpful to sometimes know the TCP window sizes of an established socket e.g. to confirm that window scaling is working or to tweak the window size to improve high-latency connections, etc etc. Currently the TCP snooper only exports the send window size, but not the receive window size. Therefore, also add the receive window size to the end of the output line. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
