In this case we leave the\n rcu protected region, so force a refcount on the skb's destination\n entry before we enter the xfrm type input/output handlers.\"\n\nOn TIPC decryption path it has the same problem, and skb_dst_force()\nshould be called before doing decryption to avoid a possible crash.\n\nShuang reported this issue when this warning is triggered:\n\n [] WARNING: include/net/dst.h:337 tipc_sk_rcv+0x1055/0x1ea0 [tipc]\n [] Kdump: loaded Tainted: G W --------- - - 4.18.0-496.el8.x86_64+debug\n [] Workqueue: crypto cryptd_queue_worker\n [] RIP: 0010:tipc_sk_rcv+0x1055/0x1ea0 [tipc]\n [] Call Trace:\n [] tipc_sk_mcast_rcv+0x548/0xea0 [tipc]\n [] tipc_rcv+0xcf5/0x1060 [tipc]\n [] tipc_aead_decrypt_done+0x215/0x2e0 [tipc]\n [] cryptd_aead_crypt+0xdb/0x190\n [] cryptd_queue_worker+0xed/0x190\n [] process_one_work+0x93d/0x17e0" |
