--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
The definition of that tcphdr type is read out of the kernel vmlinux image (if
the tapset doesn't request a header-file based cast, like e.g. inet_sock on
tapset/linux/tcp.stp line 80. The problematic @cast(... "tcphdr") bits could
be converted to @cast(... "tcphdr", "kernel<net/tcp.h>") or similar. But if
debuginfo is missing, other things will be broken too.
Could you forward the stap-report output, as requested by the [man
error::pass4] and [man error::reporting] pages? I wouldn't be surprised if the
vmlinux file was not as advertised.
