[Bug Description]
use ubuntu 20.04.2 to net card set VF and altname display blurred character
[Steps to Reproduce]
1) echo 1 > /sys/class/net/enp189s0f0/device/sriov_numvfs
2) ip a
3)
10: eno1v0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 1e:d8:e1:e9:ae:25 brd ff:ff:ff:ff:ff:ff
altname @▒ު▒
altname enp125s0f0v0
11: enp189s0f0v0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 76:ea:f4:65:dd:33 brd ff:ff:ff:ff:ff:ff
altname ▒b▒ު▒
altname ▒▒▒▒▒▒
[Actual Results]
altname ▒b▒ު▒
altname ▒▒▒▒▒▒
[Expected Results]
ok
[Reproducibility]
100%
[Additional information]
(Firmware version, kernel version, affected hardware, etc. if required):
[Resolution] |
[Impact]
When running with the HWE kernel (5.4 didn't support altnames), altnames containing garbage (uninitialized memory) may get assigned to a NIC. This is 100% reproducible on arm64.
[Test Case]
1) echo 1 > /sys/class/net/enp189s0f0/device/sriov_numvfs
2) ip a
3)
10: eno1v0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 1e:d8:e1:e9:ae:25 brd ff:ff:ff:ff:ff:ff
altname @▒ު▒
altname enp125s0f0v0
11: enp189s0f0v0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 76:ea:f4:65:dd:33 brd ff:ff:ff:ff:ff:ff
altname ▒b▒ު▒
altname ▒▒▒▒▒▒
[Fix]
There's a one liner upstream fix that simply initializes a variable:

[Impact]
When running with the HWE kernel (5.4 didn't support altnames), altnames containing garbage (uninitialized memory) may get assigned to a NIC. This is 100% reproducible on arm64. The upstream commit message suggests that this has been seen to cause segfaults.

[What Could Go Wrong]
The fix itself is innocuous - just initializing a variable to NULL. So the real risk here would seem to be limited to the common risks in updating a core package in the Ubuntu distribution. |
