Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h To help in reducing the number of include dependencies, several files were touched as they were getting needed headers indirectly for stuff they use.

[IPv4] RAW: Compact the API for the kernel The raw sockets functions are explicitly used from inside the kernel in two places: 1. in ip_local_deliver_finish to intercept skb-s 2. in icmp_error For this purposes many functions and even data structures, that are naturally internal for raw protocol, are exported. Compact the API to two functions and hide all the other (including hash table and rwlock) inside the net/ipv4/raw.c Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

[RAW]: Introduce raw_hashinfo structure The ipv4/raw.c and ipv6/raw.c contain many common code (most of which is proc interface) which can be consolidated. Most of the places to consolidate deal with the raw sockets hashtable, so introduce a struct raw_hashinfo which describes the raw sockets hash.

[RAW]: Consolidate proc interface. Both ipv6/raw.c and ipv4/raw.c use the seq files to walk through the raw sockets hash and show them. The "walking" code is rather huge, but is identical in both cases. The difference is the hash table to walk over and the protocol family to check (this was not in the first virsion of the patch, which was noticed by YOSHIFUJI) Make the ->open store the needed hash table and the family on the allocated raw_iter_state and make the start/next/stop callbacks work with it. This removes most of the code. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

[RAW]: Wrong content of the /proc/net/raw6. The address of IPv6 raw sockets was shown in the wrong format, from IPv4 ones. The problem has been introduced by the commit 42a73808ed4f30b739eb52bcbb33a02fe62ceef5 ("[RAW]: Consolidate proc interface.") Thanks to Adrian Bunk who originally noticed the problem.

[RAW]: Add raw_hashinfo member on struct proto. Sorry for the patch sequence confusion :| but I found that the similar thing can be done for raw sockets easily too late. Expand the proto.h union with the raw_hashinfo member and use it in raw_prot and rawv6_prot. This allows to drop the protocol specific versions of hash and unhash callbacks.

ipv4: ipmr: support multiple tables This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT_TABLE. The table number is stored in the raw socket data and affects all following ipmr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT_TABLE_DEFAULT) is created with a default routing rule pointing to it. Newly created pimreg devices have the table number appended ("pimregX"), with the exception of devices created in the default table, which are named just "pimreg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, IPPROTO_IP, MRT_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip mrule add iif eth0 lookup 123 # ip mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
