* [XFRM]: alg_key_len should be unsigned to avoid integer dividesEric Dumazet2008-01-291-1/+1
| | | | | | | | | | alg_key_len is currently defined as 'signed int'. This unfortunatly leads to integer divides in several paths. Converting it to unsigned is safe and saves 208 bytes of text on i386. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* [FIB]: Reduce text size of net/ipv4/fib_trie.oEric Dumazet2008-01-291-2/+2
| | | | | | | | | | | | | | | | | In struct tnode, we use two fields of 5 bits for 'pos' and 'bits'. Switching to plain 'unsigned char' (8 bits) take the same space because of compiler alignments, and reduce text size by 435 bytes on i386.

| | | | | | | | | | | | | | | | This is the core. Declare and register the pernet subsys for addrconf. The init callback the will create the devconf-s. The init_net will reuse the existing statically declared confs, so that accessing them from inside the ipv6 code will still work. The register_pernet_subsys() is moved above the ipv6_add_dev() call for loopback, because this function will need the net->devconf_dflt pointer to be already set.

That allows to access the different tables relatively to the network namespace. The modification of the signature function is reported in all the callers of the inet_addr_type using the pointer to the well known init_net.

* [NETNS]: Add netns parameter to fib_get_table/fib_new_table.Denis V. Lunev2008-01-295-32/+32
| | | | | | | | | | | This patch extends the fib_get_table and the fib_new_table functions with the network namespace pointer. That will allow to access the table relatively from the network namespace. Acked-by: Benjamin Thery <benjamin.thery@bull.net> Acked-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: Denis V.

* [IPV4]: Unify access to the routing tables.Denis V. Lunev2008-01-292-28/+40
| | | | | | | | | | | | | Replace the direct pointers to local and main tables with calls to fib_get_table() with appropriate argument. This doesn't introduce additional dereferences, but makes the access to fib tables uniform in any (CONFIG_IP_MULTIPLE_TABLES) case.

* [NETNS]: Refactor fib initialization so it can handle multiple namespaces.Denis V. Lunev2008-01-296-26/+92
| | | | | | | | | | | | This patch makes the fib to be initialized as a subsystem for the network namespaces. The code does not handle several namespaces yet, so in case of a creation of a network namespace, the creation/initialization will not occur.

* [IPV4]: Check fib4_rules_init failure.Denis V. Lunev2008-01-293-6/+28
| | | | | | | | | | | This adds error paths into both versions of fib4_rules_init (with/without CONFIG_IP_MULTIPLE_TABLES) and returns error code to the caller.
