            Bug ID: 20601
           Summary: __get_skb_iphdr() failing on 32-bit rawhide
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com
  Target Milestone: ---

On 32-bit rawhide, I'm seeing the following:

====
# stap -e 'probe tcp.ipv4.receive { printf("%s\n", saddr) }'
ERROR: read fault [man error::fault] at 0x0000005a (addr) near operator '@cast'
at /usr/local/share/systemtap/tapset/linux/ip.stp:154:10
WARNING: Number of errors: 1, skipped probes: 1
WARNING: /usr/local/bin/staprun exited with status: 1
Pass 5: run failed.  [man error::pass5]
====

This is happening because the __get_skb_iphdr() function is returning the wrong
value on 32-bit platforms. That function worked on RHEL6-era kernels, but it
fails on newer 32-bit kernels.
