In the Linux kernel, the following vulnerability has been resolved:
ice: fix PTP Call Trace during PTP release
If a PF reset occurs when the PTP state is ICE_PTP_UNINIT, then
ice_ptp_rebuild() will update the state to ICE_PTP_ERROR. This will
result in the following PTP release call trace during driver unload:
kernel BUG at lib/list_debug.c:52!
ice_ptp_release+0x332/0x3c0 [ice]
ice_deinit_features.part.0+0x10e/0x120 [ice]
ice_remove+0x100/0x220 [ice]
This was observed when passing PF1 through to a VM. ice_ptp_init()
fails because ctrl_pf is NULL and sets the state to ICE_PTP_UNINIT.
Fix by detecting the ICE_PTP_UNINIT state in ice_ptp_rebuild() and
returning without error, preventing the invalid state transition to
ICE_PTP_ERROR. The only valid path to ICE_PTP_ERROR is from
ICE_PTP_RESETTING after a failed rebuild.
