Bug ID: 2033
Summary: odp_cpuinfo_parser() causes segfault on systems where
cpu speed info is missing in sysinfo->model_str
Product: OpenDataPlane - linux- generic reference
Version: 1.7
Hardware: Other
OS: Linux
Status: UNCONFIRMED
Severity: critical
Priority: ---
Component: General ODP
Assignee: lng-odp@lists.linaro.org
Reporter: pasi.orp...@nokia.com
Overview: odp_cpuinfo_parser() expects to find "@ x.xGHz" in sysinfo->model_str
and when it fails causes segmentation fault.
The used environment was KVM virtualized guest in which the first 8 lines of
/proc/cpuinfo looks like this:
processor : 47
vendor_id : GenuineIntel
cpu family : 6
model : 42
model name : Intel Xeon E312xx (Sandy Bridge)
stepping : 1
microcode : 0x1
cpu MHz : 2394.230
...
No trailing "@ x.xGHz" in model name.
Steps to Reproduce:
1. System where the cpu model name does not include speed
2. Run any application than calls odp_init_global()
Results: SEGFAULT at application startup.
Line that segfaults:
at ../../../platform/linux-generic/arch/x86/odp_sysinfo_parse.c:27
27 *(pos - 1) = '\0';
Additional Information:
The cpu MHz is displayed in its own field so why not get it from there?
