* [TCP]: Do not use inet->id of global tcp_socket when sending RST.Alexey Kuznetsov2006-03-22
| | | | | | | | | | | | | | | | | | | | | | | The problem is in ip_push_pending_frames(), which uses: if (!df) { __ip_select_ident(iph, &rt->u.dst, 0); } else { iph->id = htons(inet->id++); } instead of ip_select_ident(). Right now I think the code is a nonsense. Most likely, I copied it from old ip_build_xmit(), where it was really special, we had to decide whether to generate unique ID when generating the first (well, the last) fragment. In ip_push_pending_frames() it does not make sense, it should use plain ip_select_ident() instead. Signed-off-by: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru> Signed-off-by: David S.

* [NETFILTER]: nf_conntrack: support for layer 3 protocol load on demandPablo Neira Ayuso2006-03-22
| | | | | | | | | | | | | | x_tables matches and targets that require nf_conntrack_ipv[4|6] to work don't have enough information to load on demand these modules. This patch introduces the following changes to solve this issue: o nf_ct_l3proto_try_module_get: try to load the layer 3 connection tracker module and increases the refcount. o nf_ct_l3proto_module put: drop the refcount of the module.

* [NETFILTER]: ctnetlink: Fix expectaction mask dumpingPablo Neira Ayuso2006-03-22
| | | | | | | | | | | | | | | | | | | | The expectation mask has some particularities that requires a different handling. The protocol number fields can be set to non-valid protocols, ie. l3num is set to 0xFFFF. Since that protocol does not exist, the mask tuple will not be dumped. Moreover, this results in a kernel panic when nf_conntrack accesses the array of protocol handlers, that is PF_MAX (0x1F) long. This patch introduces the function ctnetlink_exp_dump_mask, that correctly dumps the expectation mask. Such function uses the l3num value from the expectation tuple that is a valid layer 3 protocol number. The value of the l3num mask isn't dumped since it is meaningless from the userspace side.

* [X25]: dte facilities 32 64 ioctl conversionShaun Pereira2006-03-22

* [X25]: allow ITU-T DTE facilities for x25Shaun Pereira2006-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allows use of the optional user facility to insert ITU-T (http://www.itu.int/ITU-T/) specified DTE facilities in call set-up x25 packets. This feature is optional; no facilities will be added if the ioctl is not used, and call setup packet remains the same as before. If the ioctls provided by the patch are used, then a facility marker will be added to the x25 packet header so that the called dte address extension facility can be differentiated from other types of facilities (as described in the ITU-T X.25 recommendation) that are also allowed in the x25 packet header. Facility markers are made up of two octets, and may be present in the x25 packet headers of call-request, incoming call, call accepted, clear request, and clear indication packets. The first of the two octets represents the facility code field and is set to zero by this patch. The second octet of the marker represents the facility parameter field and is set to 0x0F because the marker will be inserted before ITU-T type DTE facilities. Since according to ITU-T X.25 Recommendation X.25(10/96)- 7.1 "All networks will support the facility markers with a facility parameter field set to all ones or to 00001111", therefore this patch should work with all x.25 networks. While there are many ITU-T DTE facilities, this patch implements only the called and calling address extension, with placeholders in the x25_dte_facilities structure for the rest of the facilities. Testing: This patch was tested using a cisco xot router connected on its serial ports to an X.25 network, and on its lan ports to a host running an xotd daemon. It is also possible to test this patch using an xotd daemon and an x25tap patch, where the xotd daemons work back-to-back without actually using an x.25 network. See www.fyonne.net for details on how to do this.

* [BRIDGE]: allow show/store of group multicast addressStephen Hemminger2006-03-21
| | | | | | | | | | | | | | Bridge's communicate with each other using Spanning Tree Protocol over a standard multicast address. There are times when testing or layering bridges over existing topologies or tunnels, when it is useful to use alternative multicast addresses for STP packets. The 802.1d standard has some unused addresses, that can be used for this. This patch is restrictive in that it only allows one of the possible addresses in the standard.

* [BRIDGE]: use llc for receiving STP packetsStephen Hemminger2006-03-21
| | | | | | | | | | | | | | | Use LLC for the receive path of Spanning Tree Protocol packets. This allows link local multicast packets to be received by other protocols (if they care), and uses the existing LLC code to get STP packets back into bridge code. The bridge multicast address is also checked, so bridges using other link local multicast addresses are ignored. This allows for use of different multicast addresses to define separate STP domains.
