ipv4/route: arg delay is useless in rt_cache_flush()

2012-09-18T19:44:34Z

Since route cache deletion (89aef8921bfbac22f), delay is no more used. Remove it. Signed-off-by: Nicolas Dichtel Acked-by: Eric Dumazet Signed-off-by: David S. Miller

ipv4: Don't store a rule pointer in fib_result.

2012-07-13T15:21:29Z

We only use it to fetch the rule's tclassid, so just store the tclassid there instead. This also decreases the size of fib_result by a full 8 bytes on 64-bit. On 32-bits it's a wash. Signed-off-by: David S. Miller

ipv4: Avoid overhead when no custom FIB rules are installed.

2012-07-06T05:13:13Z

If the user hasn't actually installed any custom rules, or fiddled with the default ones, don't go through the whole FIB rules layer. It's just pure overhead. Instead do what we do with CONFIG_IP_MULTIPLE_TABLES disabled, check the individual tables by hand, one by one. Also, move fib_num_tclassid_users into the ipv4 network namespace.

ipv4: Elide fib_validate_source() completely when possible.

2012-06-29T08:36:36Z

If rpfilter is off (or the SKB has an IPSEC path) and there are not tclassid users, we don't have to do anything at all when fib_validate_source() is invoked besides setting the itag to zero. We monitor tclassid uses with a counter (modified only under RTNL and marked __read_mostly) and we protect the fib_validate_source() real work with a test against this counter and whether rpfilter is to be done. Having a way to know whether we need no tclassid processing or not also opens the door for future optimized rpfilter algorithms that do not perform full FIB lookups. Signed-off-by: David S. Miller

ipv4: Stop using NLA_PUT*().

2012-04-02T08:33:43Z

These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S. Miller

net: ipv4: export fib_lookup and fib_table_lookup

2011-12-04T21:43:33Z

The reverse path filter module will use fib_lookup. If CONFIG_IP_MULTIPLE_TABLES is not set, fib_lookup is only a static inline helper that calls fib_table_lookup, so export that too. Signed-off-by: Florian Westphal Acked-by: David S. Miller Signed-off-by: Pablo Neira Ayuso

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30Z

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker

ipv4: Use flowi4 in FIB layer.

ipv4: Pass ipv4 flow objects into fib_lookup() paths.

2011-03-12T23:08:47Z

To start doing these conversions, we need to add some temporary flow4_* macros which will eventually go away when all the protocol code paths are changed to work on AF specific flowi objects. Signed-off-by: David S. Miller

ipv4: Use const'ify fib_result deep in the route call chains.

2011-02-17T23:54:42Z

The only troublesome bit here is __mkroute_output which wants to override res->fi and res->type, compute those in local variables instead. Signed-off-by: David S. Miller
