Description
In the Linux kernel, the following vulnerability has been resolved:
ice: ptp: don't WARN when controlling PF is unavailable
In VFIO passthrough setups, it is possible to pass through only a PF
which doesn't own the source timer. In that case the PTP controlling PF
(adapter->ctrl_pf) is never initialized in the VM, so ice_get_ctrl_ptp()
returns NULL and triggers WARN_ON() in ice_ptp_setup_pf().
Since this is an expected behavior in that configuration, replace
WARN_ON() with an informational message and return -EOPNOTSUPP.
Affected configurations
• linux linux kernel (>= 6.12.11 < 6.13)
• linux linux kernel (>= 6.13 < 6.18.24)
• linux linux kernel (>= 6.19 < 6.19.14)
• linux linux kernel 7.0
