2013-08-29xen-netback: rename functionsWei Liu3-133/+134
As we move to 1:1 model and melt xen_netbk and xenvif together, it would be better to use single prefix for all functions in xen-netback. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-29xen-netback: switch to NAPI + kthread 1:1 modelWei Liu3-507/+351
This patch implements 1:1 model netback. NAPI and kthread are utilized to do the weight-lifting job: - NAPI is used for guest side TX (host side RX) - kthread is used for guest side RX (host side TX) Xenvif and xen_netbk are made into one structure to reduce code size. This model provides better scheduling fairness among vifs. It is also prerequisite for implementing multiqueue for Xen netback.

2013-08-28netfilter: add SYNPROXY core/targetPatrick McHardy13-1/+1066
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.

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.

2013-08-28netfilter: ip[6]t_REJECT: tcp-reset using wrong MAC source if bridgedPhil Oester2-2/+39
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>

2013-08-27net: tcp_probe: allow more advanced ingress filtering by markDaniel Borkmann1-4/+11
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 Drake1-1/+1
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>
