Subject: [Bug 201849] New: hw csum failure - reproducible error
https://bugzilla.kernel.org/show_bug.cgi?id=201849
Bug ID: 201849
Summary: hw csum failure - reproducible error
Product: Networking
Version: 2.5
Kernel Version: 4.19.5-1.el7.elrepo.x86_64
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: IPV4
Assignee: stephen@...workplumber.org
Reporter: jkyriannis@...ernet.org
Regression: No
On prior versions of the 4.19 kernel, including 4.19.5-1.el7.elrepo.x86_64, a
kernel error is generated whenever an IPv4 IGMP v2 query is received. This is
reproducible and has been confirmed on a quiet subnet containing only the host
and a router (manufactured by Juniper). Please see the tcpdump capture of the
packet followed by the immediate kernel error below. Below that, follows some
additional diagnostic output. If any additional information is needed, please
let me know. There are other bugs logged against "hw csum failure" messages,
but non correlate to this stack trace and diagnosis.
