Description Petr Muller 2011-01-14 15:34:03 UTC

Description of problem:
# stap -p4 -v /usr/share/systemtap/testsuite/buildok/fortyfive.stp
Pass 1: parsed user script and 72 library script(s) using 19520virt/12080res/2004shr kb, in 530usr/20sys/548real ms.

Pass 4: compiled C into "stap_e92c7152931f26eba30648e7e6a7578e_7473.ko" in 3360usr/260sys/3508real ms.
Pass 4: compilation failed.  Try again with another '--vp 0001' option.

Version-Release number of selected component (if applicable):
systemtap-1.3-4.el4
the testcase if present only in systemtap-testsuite-1.3-4, but systemtap-0.6.2-2.el4_8.3 (4.8) compiles the identical script, so it is a regression

How reproducible:
always on i386 and x86_64, I don't have results from different architectures

Steps to Reproduce:
1. # stap -p4 -v /usr/share/systemtap/testsuite/buildok/fortyfive.stp
2.
3.
  
Actual results:
fail in pass 4

Expected results:
no fail

Comment 2 David Smith 2011-01-18 20:19:38 UTC

I've duplicated this bug.  After some investigation, the problem was a change in the target_set.stp tapset.  This tapset was changed to use dwarfless probes ('nd_syscall' probes, which map to 'kprobe.function' probes), which 2.6.9 kernels don't support.

So, I changed the target_set.stp to use dwarf probes ('syscall' probes, which map to 'kernel.function' probes) for 2.6.9 kernels.

Upstream commit 4ec30a2 will need to be backported to fix this issue.
