NTB: ntb_netdev: Preserve RX queue depth on allocation failure
In the Linux kernel, the following vulnerability has been resolved: NTB: ntb_netdev: Preserve RX queue depth on allocation failure ntb_netdev_rx_handler() hands the received skb to the network stack before allocating its replacement. If the allocation fails, nothing is reposted. Every failure therefore takes one buffer out of the RX queue while the interface remains up, and enough failures eventually stall reception. A retry path could refill the queue later, but ntb_netdev has none. Allocate the replacement first instead. If that fails, drop the packet and repost the same skb. This keeps the queue full and lets packet delivery resume as soon as memory is available again.
