When sk_msg_alloc()\nreturns -ENOMEM error, tcp_bpf_sendmsg() goes to wait_for_memory. If partial\nmemory has been alloced by sk_msg_alloc(), that is, msg_tx->sg.size is\ngreater than osize after sk_msg_alloc(), memleak occurs. To fix we use\nsk_msg_trim() to release the allocated memory, then goto wait for memory.\n\nOther call paths of sk_msg_alloc() have the similar issue, such as\ntls_sw_sendmsg(), so handle sk_msg_trim logic inside sk_msg_alloc(),\nas Cong Wang suggested.\n\nThis issue can cause the following info:\nWARNING: CPU: 3 PID: 7950 at net/core/stream.c:208 sk_stream_kill_queues+0xd4/0x1a0\nCall Trace:\n
