[Bug tapsets/10115] New: Problems

[nuhn at physik dot rwth-aachen dot de]

I have some problems with the 0.9.7 Version of Systemtap.
Scripts than run with 0.9 don't run anymore on 0.9.7.

I think it affects the "@cast" stuff, in my example this affects "inet_sock.stp"

Changing:
daddr = @cast(sock, "inet_sock", "kernel")->inet->daddr;

To:
daddr = @cast(sock, "inet_sock", "kernel<linux/ip.h>")->inet->daddr;

Fixes the problem.

I have a 2.6.9 Kernel.

It is possible that the fix for bug #9932 modified the behavior of '@cast' a
bit, causing this problem.

Your patch looks reasonable.  Is this the only example of this problem or are
there others?

Believed fixed.  Other @casts() in the tapsets may benefit
from explicit kernel<FOO.h> decorations to decouple more
from debug data.
