[Bug 401202] Re: Resolver ignores ndots option

[Martin Stepanek]

Tried and got the same result on the recent Karmic and Lucid kernels as well. My notebook unfortunately does not boot with a standard mainstream kernel, so I can not verify it.
Just to verify we understand each other, please look at the attached file. The home domain stemar.cz has been deliberately modified for this test in order to return a positive response for any request. As you can see, the dig returns NXDOMAIN for a.nonexistingdomain.com. The host command however continues with searching for a.nonexistingdomain.com.stemar.cz which is then successful. It should not be correct as a.nonexistingdomain.com contains more that ndots option dots. Unfortunately, the same way as the host command does any other apps (Firefox, Thunderbird, ping, etc.). From this I believe the problem is in the kernel resolver procedure.
