[Bug 1324558] [NEW] SRU for biosdevname returns identical names for two different devices.

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Jorge Niedbalski (niedbalski):

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: #1293633 and LP:
#1284043

Fix :

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

Test Case :

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

If 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
