Revision history for this message
Jorge Niedbalski (niedbalski) wrote : SRU for biosdevname returns identical names for two different devices.

SRU justification :

The 'addslot' function can return the same value for two or more interfaces (same dev->index_in_slot), causing the interfaces on a given PCI slot get same port number. This could trigger a rename to a different name space (such as rename*) presented on LP : #1284043.

Example problematic behavior:

# biosdevname -i em1
em1
# biosdevname -i em2
em3
# biosdevname -i em3
em4
# biosdevname -i rename3
em2

Another customer points:

On first reboot the names are different. eth0 renamed to p4p1 and eth1 renamed to p4p2
then on next reboot eth0 renamed to p4p1 and eth1 renamed to rename3

Impact :

Without this SRU customer will experience erroneous output from biosdevname ( renamed interfaces) as noticed on LP: #293633 and LP: #1284043

Fix :

Apply patches from upstream https://bugzilla.redhat.com/show_bug.cgi?id=782145

Test Case :

1) Having one or more PCI ethernet cards attached
2) Having one or more onboard ethernet cards.
3) Run biosdevname -d and notice the renamed interfaces.

I f you get some rename* interfaces this bug isn't fixed, if you can see the correct bios hardware names associated with the interface, it's fixed.

Regression :

None expected
