net: Fix routing tables with id > 255 for legacy software

2008-06-10T22:44:49+00:00

Most legacy software do not like tables > 255 as rtm_table is u8
so tb_id is sent &0xff and it is possible to mismatch for example
table 510 with table 254 (main).

This patch introduces RT_TABLE_COMPAT=252 so the code uses it if
tb_id > 255. It makes such old applications happy, new
ones are still able to use RTA_TABLE to get a proper table id.

[NETNS]: Lookup in FIB semantic hashes taking into account the namespace.

2008-02-01T03:28:41+00:00

The namespace is not available in the fib_sync_down_addr, add it as a
parameter.

Looking up a device by the pointer to it is OK. Looking up using a
result from fib_trie/fib_hash table lookup is also safe. No need to
fix that at all.  So, just fix lookup by address and insertion to the
hash table path.

[NETNS]: Add a namespace mark to fib_info.

2008-02-01T03:28:40+00:00

This is required to make fib_info lookups namespace aware. In the
other case initial namespace devices are marked as dead in the local
routing table during other namespace stop.

[IPV4]: fib_sync_down rework.

2008-02-01T03:28:39+00:00

fib_sync_down can be called with an address and with a device. In
reality it is called either with address OR with a device. The
codepath inside is completely different, so lets separate it into two
calls for these two cases.

[NETNS]: Pass correct namespace in context fib_check_nh.

2008-01-28T23:10:21+00:00

Correct network namespace is already used in fib_check_nh. Re-work its
usage for better readability and pass into fib_lookup &
inetdev_by_index.

[IPV4] FIB: printk related cleanups

2008-01-28T23:01:55+00:00

printk related cleanups:
 * Get rid of unused printk wrappers.
 * Make bug checks into KERN_WARNING because KERN_DEBUG gets ignored
 * Turn one cryptic old message into something real
 * Make sure all messages have KERN_XXX
