[Impact]
* Microsoft has requested a patch to address a kernel panic issue similar to the upstream issue here - https://patchwork.kernel.org/project/netdevbpf/patch/20240731213046.6194-2-pablo@netfilter.org/
[Fix]
* Clean cherry-pick upstream commit 5830aa863981: "netfilter: iptables: Fix null-ptr-deref in iptable_nat_table_init()"
[Test Plan]
* Build and boot tested
[Where problems could occur]
* Low regression risk, mostly shifting logic
* Change to order of register_pernet_subsys() and xt_register_template() could expose some other logic being held together under race condition
[Other info]
* SF #00391736 |
