Title
PCI/ASPM: Fix link state exit during switch upstream function removal
Summary
In the Linux kernel, the following vulnerability has been resolved: PCI/ASPM: Fix link state exit during switch upstream function removal Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free"), we would free the ASPM link only after the last function on the bus pertaining to the given link was removed. That was too late. If function 0 is removed before sibling function, link->downstream would point to free'd memory after. After above change, we freed the ASPM parent link state upon any function removal on the bus pertaining to a given link. That is too early. If the link is to a PCIe switch with MFD on the upstream port, then removing functions other than 0 first would free a link which still remains parent_link to the remaining downstream ports. The resulting GPFs are especially frequent during hot-unplug, because pciehp removes devices on the link bus in reverse order. On that switch, function 0 is the virtual P2P bridge to the internal bus. Free exactly when function 0 is removed -- before the parent link is obsolete, but after all subordinate links are gone.

If function 0 is removed before sibling function,\nlink-\u003edownstream would point to free\u0027d memory after.\n\nAfter above change, we freed the ASPM parent link state upon any function\nremoval on the bus pertaining to a given link.\n\nThat is too early. If the link is to a PCIe switch with MFD on the upstream\nport, then removing functions other than 0 first would free a link which\nstill remains parent_link to the remaining downstream ports.\n\nThe resulting GPFs are especially frequent during hot-unplug, because\npciehp removes devices on the link bus in reverse order.\n\nOn that switch, function 0 is the virtual P2P bridge to the internal bus.\nFree exactly when function 0 is removed -- before the parent link is\nobsolete, but after all subordinate links are gone.\n\n[kwilczynski: commit log]"

Los GPF resultantes son especialmente frecuentes durante la desconexi\u00f3n en caliente, ya que pciehp elimina los dispositivos del bus de enlace en orden inverso. En ese conmutador, la funci\u00f3n 0 es el puente P2P virtual al bus interno. Se libera exactamente cuando se elimina la funci\u00f3n 0: antes de que el enlace principal quede obsoleto, pero despu\u00e9s de que todos los enlaces subordinados desaparezcan.
