I took on Ben's challenge to increase the number of possible routing tables,
these are the resulting patches.
I am seeing problems..though they could be with the way I'm using the tool
or pehaps I patched the kernel incorrectly.
I applied the 3 patches to 2.6.17..all patches applied without problem,
but with a few lines of fuzz. I get the same behaviour with and
without the new 'ip' patches applied.
If I do an 'ip ru show', then I see lots of tables, though not all it seems.
(I have not tried beyond 205 yet). But, if I do an 'ip route show table XX',
then I see nothing or incorrect values.
For my test, I am creating 200 virtual interfaces (mac-vlans in my case, but
802.1q should work equally well.) I am giving them all IP addrs on the same
subnet, and a routing table for each source IP addr.
The commands I run to generate the routing tables are found in this file:
http://www.candelatech.com/oss/gc.txt
When I change back to kernel 2.6.16.16 with only my patchset applied, things
seem to be working, so it looks like an issue with the new kernel patches.
I can provide access to this machine as well as my full patch set, etc...
For whatever reason, table 5 does appear in a bizarre fashion:
