2006-12-02[XFRM]: Fix aevent structuring to be more complete.Jamal Hadi Salim1-0/+2
aevents can not uniquely identify an SA. We break the ABI with this patch, but consensus is that since it is not yet utilized by any (known) application then it is fine (better do it now than later).

2006-12-02[NETFILTER]: nf_conntrack/nf_nat: add PPTP helper portPatrick McHardy2-0/+433
Add nf_conntrack port of the PPtP conntrack/NAT helper. Since there seems to be no IPv6-capable PPtP implementation the helper only support IPv4. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-02[NETFILTER]: nf_conntrack/nf_nat: add IRC helper portPatrick McHardy1-0/+15
Add nf_conntrack port of the IRC conntrack/NAT helper. Since DCC doesn't support IPv6 yet, the helper is still IPv4 only. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-12-02[NET]: Accept wildcard delimiters in in[46]_ptonPatrick McHardy1-2/+2
Accept -1 as delimiter to abort parsing without an error at the first unknown character. This is needed by the upcoming nf_conntrack SIP helper, where addresses are delimited by either '\r' or '\n' characters. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2006-12-02[NETFILTER]: ebtables: add --snap-arp optionBart De Schuymer2-0/+5
The attached patch adds --snat-arp support, which makes it possible to change the source mac address in both the mac header and the arp header with one rule. Signed-off-by: Bart De Schuymer <bdschuym@pandora.be> Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: x_tables: add NFLOG targetPatrick McHardy4-2/+21
Add new NFLOG target to allow use of nfnetlink_log for both IPv4 and IPv6. Currently we have two (unsupported by userspace) hacks in the LOG and ULOG targets to optionally call to the nflog API. They lack a few features, namely the IPv4 and IPv6 LOG targets can not specify a number of arguments related to nfnetlink_log, while the ULOG target is only available for IPv4. Remove those hacks and add a clean way to use nfnetlink_log. Signed-off-by: Patrick McHardy <kaber@trash.net>

2006-12-02[NETFILTER]: sip conntrack: better NAT handlingPatrick McHardy1-1/+4
The NAT handling of the SIP helper has a few problems: - Request headers are only mangled in the reply direction, From/To headers not at all, which can lead to authentication failures with DNAT in case the authentication domain is the IP address - Contact headers in responses are only mangled for REGISTER responses - Headers may be mangled even though they contain addresses not participating in the connection, like alternative addresses - Packets are droppen when domain names are used where the helper expects IP addresses This patch takes a different approach, instead of fixed rules what field to mangle to what content, it adds symetric mapping of From/To/Via/Contact headers, which allows to deal properly with echoed addresses in responses and foreign addresses not belonging to the connection. Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: sip conntrack: do case insensitive SIP header searchPatrick McHardy1-1/+2
SIP headers are generally case-insensitive, only SDP headers are case sensitive. Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: sip conntrack: minor cleanupPatrick McHardy1-18/+10
- Use enum for header field enumeration - Use numerical value instead of pointer to header info structure to identify headers, unexport ct_sip_hdrs - group SIP and SDP entries in header info structure - remove double forward declaration of ct_sip_get_info Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: conntrack: add '_get' to {ip, nf}_conntrack_expect_findYasuyuki Kozakai1-1/+1

2006-12-02[NETFILTER]: nf_conntrack: automatic sysctl registation for conntrack protocolsPatrick McHardy1-0/+10
Add helper functions for sysctl registration with optional instantiating of common path elements (like net/netfilter) and use it for support for automatic registation of conntrack protocol sysctls. Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[DCCP]: Tidy up unused structuresGerrit Renker1-3/+1
This removes and cleans up unused variables and structures which have become unnecessary following the introduction of the EWMA patch to automatically track the CCID 3 receiver/sender packet sizes `s'. It deprecates the PACKET_SIZE socket option by returning an error code and printing a deprecation warning if an application tries to read or write this socket option.

2006-12-02[DCCP]: Remove allocation of sysctl numbersGerrit Renker1-14/+0
This is in response to a request sent earlier by Eric W. Biederman and replaces all sysctl numbers for net.dccp.default with CTL_UNNUMBERED. It has been tested to compile and to work. Commiter note: I've removed the use of CTL_UNNUMBERED, not setting .ctl_name sets it to 0, that is the what CTL_UNNUMBERED is, reason is to avoid unneeded source code cluttering.

2006-12-02[NET]: Supporting UDP-Lite (RFC 3828) in LinuxGerrit Renker3-0/+14
This is a revision of the previously submitted patch, which alters the way files are organized and compiled in the following manner: * UDP and UDP-Lite now use separate object files * source file dependencies resolved via header files net/ipv{4,6}/udp_impl.h * order of inclusion files in udp.c/udplite.c adapted accordingly [NET/IPv4]: Support for the UDP-Lite protocol (RFC 3828) This patch adds support for UDP-Lite to the IPv4 stack, provided as an extension to the existing UDPv4 code: * generic routines are all located in net/ipv4/udp.c * UDP-Lite specific routines are in net/ipv4/udplite.c * MIB/statistics support in /proc/net/snmp and /proc/net/udplite * shared API with extensions for partial checksum coverage [NET/IPv6]: Extension for UDP-Lite over IPv6 It extends the existing UDPv6 code base with support for UDP-Lite in the same manner as per UDPv4. In particular, * UDPv6 generic and shared code is in net/ipv6/udp.c * UDP-Litev6 specific extensions are in net/ipv6/udplite.c * MIB/statistics support in /proc/net/snmp6 and /proc/net/udplite6 * support for IPV6_ADDRFORM * aligned the coding style of protocol initialisation with af_inet6.c * made the error handling in udpv6_queue_rcv_skb consistent; to return `-1' on error on all error cases * consolidation of shared code [NET]: UDP-Lite Documentation and basic XFRM/Netfilter support The UDP-Lite patch further provides * API documentation for UDP-Lite * basic xfrm support * basic netfilter support for IPv4 and IPv6 (LOG target) Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.
