Attached is a patch to net/ipv4/route.c (against 2.4.23, sorry) to
combat the 'dst cache full' issue. Essentially, there's a machine that I
have access to (a router) that will report 'dst cache full', and
immediately cease dealing with any IPv4 traffic. I found the attached
patch against 2.0, and forward-ported it to 2.4. As this issue only
crops up randomly every couple of weeks, I can't tell you whether it's
worked or not. All I know is that it hasn't eaten my firstborn so far:
given a quick spin, it seemed to work OK, but whether or not it solves
the problem is a different matter.
I also have /proc/net dumps of the machine from before and after it
died, if anyone wants them.
So, is this patch at all sane?
Please CC me: I don't subscribe.
