All Xen frontend drivers have a couple of identically named functions which makes figuring out which device went wrong from a stacktrace harder than it needs to be. Rename them to something specificto the device type. Signed-off-by:

Via setsockopt it is possible to reduce the socket RX buffer (SO_RCVBUF). TCP method to select the initial window and window scaling option in tcp_select_initial_window() currently misbehaves and do not consider a reduced RX socket buffer via setsockopt. Even though the server's RX buffer is reduced via setsockopt() to 256 byte (Initial Window 384 byte => 256 * 2 - (256 * 2 / 4)) the window scale option is still 7: 192.168.1.38.40676 > 78.47.222.210.5001: Flags [S], seq 2577214362, win 5840, options [mss 1460,sackOK,TS val 338417 ecr 0,nop,wscale 0], length 0 78.47.222.210.5001 > 192.168.1.38.40676: Flags [S.], seq 1570631029, ack 2577214363, win 384, options [mss 1452,sackOK,TS val 2435248895 ecr 338417,nop,wscale 7], length 0 192.168.1.38.40676 > 78.47.222.210.5001: Flags [.], ack 1, win 5840, options [nop,nop,TS val 338421 ecr 2435248895], length 0 Within tcp_select_initial_window() the original space argument - a representation of the rx buffer size - is expanded during tcp_select_initial_window(). Only sysctl_tcp_rmem[2], sysctl_rmem_max and window_clamp are considered to calculate the initial window. This patch adjust the window_clamp argument if the user explicitly reduce the receive buffer.

PPP: introduce "pptp" module which implements point-to-point tunneling protocol using pppox framework NET: introduce the "gre" module for demultiplexing GRE packets on version criteria (required to pptp and ip_gre may coexists) NET: ip_gre: update to use the "gre" module This patch introduces then pptp support to the linux kernel which dramatically speeds up pptp vpn connections and decreases cpu usage in comparison of existing user-space implementation (poptop/pptpclient). There is accel-pptp project (https://sourceforge.net/projects/accel-pptp/ ) to utilize this module, it contains plugin for pppd to use pptp in client-mode and modified pptpd (poptop) to build high-performance pptp NAS. There was many changes from initial submitted patch, most important are: 1. using rcu instead of read-write locks 2. using static bitmap instead of dynamically allocated 3. using vmalloc for memory allocation instead of BITS_PER_LONG + __get_free_pages 4. fixed many coding style issues Thanks to Eric Dumazet.

net/sched: add ACT_CSUM action to update packets checksums ACT_CSUM can be called just after ACT_PEDIT in order to re-compute some altered checksums in IPv4 and IPv6 packets. The following checksums are supported by this patch: - IPv4: IPv4 header, ICMP, IGMP, TCP, UDP & UDPLite - IPv6: ICMPv6, TCP, UDP & UDPLite It's possible to request in the same action to update different kind of checksums, if the packets flow mix TCP, UDP and UDPLite, ... An example of usage is done in the associated iproute2 patch. Version 3 changes: - remove useless goto instructions - improve IPv6 hop options decoding Version 2 changes: - coding style correction - remove useless arguments of some functions - use stack in tcf_csum_dump() - add tcf_csum_skb_nextlayer() to factor code Signed-off-by:
