Christoph Paasch f2feaefdab tcp: Don't access TCP_SKB_CB before initializing it ... Since commit eeea10b83a ("tcp: add tcp_v4_fill_cb()/tcp_v4_restore_cb()"), tcp_vX_fill_cb is only called after tcp_filter(). That means, TCP_SKB_CB(skb)->end_seq still points to the IP-part of the cb. We thus should not mock with it, as this can trigger bugs (thanks syzkaller): [ 12.349396] ================================================================== [ 12.350188] BUG: KASAN: slab-out-of-bounds in ip6_datagram_recv_specific_ctl+0x19b3/0x1a20 [ 12.351035] Read of size 1 at addr ffff88006adbc208 by task test_ip6_datagr/1799 Setting end_seq is actually no more necessary in tcp_filter as it gets initialized later on in tcp_vX_fill_cb.
