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

2012-09-18T19:44:34+00:00

Since route cache deletion (89aef8921bfbac22f), delay is no
more used. Remove it.

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

2012-07-13T15:21:29+00:00

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.

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

2012-07-06T05:13:13+00:00

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.

2012-06-29T08:36:36+00:00

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.

ipv4: Stop using NLA_PUT*().

2012-04-02T08:33:43+00:00

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.

net: ipv4: export fib_lookup and fib_table_lookup

2011-12-04T21:43:33+00:00

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.

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

2011-10-31T23:30:30+00:00

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.

ipv4: Use flowi4 in FIB layer.

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

2011-03-12T23:08:47+00:00

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.
