WebIn order to move nf_conntrack_ecache to global (not pernet) netns event pointer again the nfnetlink apis need to survive attempts to send a netlink message after the socket has been destroyed in nfnetlink netns exit function. Set the pernet socket to null in the pre_exit handler and close it in the exit_batch handler via a 'stash' pointer. WebIf this option is enabled, the connection tracking code will provide userspace with connection tracking events via ctnetlink. The default allocates the extension if a userspace program is listening to ctnetlink events. nf_conntrack_expect_max - INTEGER. Maximum size of expectation table.

WebNov 23, 2024 · When IPv6 connection tracking splits up a defragmented packet into its original fragments, the packets are taken from a list and are passed to the network stack with skb->next still set. This causes dev_hard_start_xmit to treat them as GSO fragments, resulting in a use after free when connection tracking handles the next fragment. http://visa.lab.asu.edu/gitlab/fstrace/android-kernel-msm-hammerhead-3.4-marshmallow-mr3/commit/19abb7b090a6bce88d4e9b2914a0367f4f684432
