CVE-2024-57933: gve: guard XSK operations on the existence of queues
In the Linux kernel, the following vulnerability has been resolved:
gve: guard XSK operations on the existence of queues
This patch predicates the enabling and disabling of XSK pools on the existence of queues. As it stands, if the interface is down, disabling or enabling XSK pools would result in a crash, as the RX queue pointer would be NULL. XSK pool registration will occur as part of the next interface up.
Similarly, xskwakeup needs be guarded against queues disappearing while the function is executing, so a check against the GVEPRIVFLAGSNAPIENABLED flag is added to synchronize with the disabling of the bit and the synchronizenet() in gveturndown.
