Bug ID: 1628
Summary: Multi-process sample app requires exact memory mapping
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: examples
Assignee: dev@dpdk.org
Reporter: nandinipersad361@gmail.com
Target Milestone: ---
The multi-process example application assumes that it is possible to map the
hugepage memory to the same virtual addresses in client and server
applications. Occasionally, very rarely with 64-bit, this does not occur and a
client application will fail on startup. The Linux “address-space layout
randomization” security feature can sometimes cause this to occur.
Implication:
A multi-process client application fails to initialize.
Resolution/Workaround:
See the “Multi-process Limitations” section in the DPDK Programmer’s Guide for
more information.
Affected Environment/Platform:
All.
Driver/Module:
Multi-process example application
