Bug ID: 1655
Summary: Kernel crash when hot-unplug igb_uio device while DPDK
application is running
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: netuio
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When device has been bound to igb_uio driver and application is running, hot-unplugging the device may cause kernel crash.
Reason:
When device is hot-unplugged, igb_uio driver will be removed which will destroy UIO resources. Later trying to access any UIO resource will cause kernel crash.
Resolution/Workaround:
If using DPDK for PCI HW hot-unplug, prefer to bind device with VFIO instead of IGB_UIO.
Affected Environment/Platform:
ALL.
Driver/Module:igb_uio module.
