Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: ice: fix FDIR CTRL VSI resource leak in ice_reset_all_vfs() Resetting all VFs causes resource leak on VFs with FDIR filters enabled as CTRL VSIs are only invalidated and not freed. Fix by using ice_vf_ctrl_vsi_release() instead of ice_vf_ctrl_invalidate_vsi() which aligns behavior with the ice_reset_vf() function. Reproduction: echo 1 > /sys/class/net/$pf/device/sriov_numvfs ethtool -N $vf flow-type ether proto 0x9000 action 0 echo 1 > /sys/class/net/$pf/device/reset
