Title
bpf, sockmap: Fix more uncharged while msg has more_data
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix more uncharged while msg has more_data In tcp_bpf_send_verdict(), if msg has more data after tcp_bpf_sendmsg_redir(): tcp_bpf_send_verdict() tosend = msg->sg.size //msg->sg.size = 22220 case __SK_REDIRECT: sk_msg_return() //uncharged msg->sg.size(22220) sk->sk_forward_alloc tcp_bpf_sendmsg_redir() //after tcp_bpf_sendmsg_redir, msg->sg.size=11000 goto more_data; tosend = msg->sg.size //msg->sg.size = 11000 case __SK_REDIRECT: sk_msg_return() //uncharged msg->sg.size(11000) to sk->sk_forward_alloc The msg->sg.size(11000) has been uncharged twice, to fix we can charge the remaining msg->sg.size before goto more data. This issue can cause the following info: WARNING: CPU: 0 PID: 9860 at net/core/stream.c:208 sk_stream_kill_queues+0xd4/0x1a0 Call Trace: <TASK> inet_csk_destroy_sock+0x55/0x110 __tcp_close+0x279/0x470 tcp_close+0x1f/0x60 inet_release+0x3f/0x80 __sock_release+0x3d/0xb0 sock_close+0x11/0x20 __fput+0x92/0x250 task_work_run+0x6a/0xa0 do_exit+0x33b/0xb60 do_group_exit+0x2f/0xa0 get_signal+0xb6/0x950 arch_do_signal_or_restart+0xac/0x2a0 ? vfs_write+0x237/0x290 exit_to_user_mode_prepare+0xa9/0x200 syscall_exit_to_user_mode+0x12/0x30 do_syscall_64+0x46/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae </TASK> WARNING: CPU: 0 PID: 2136 at net/ipv4/af_inet.c:155 inet_sock_destruct+0x13c/0x260 Call Trace: <TASK> __sk_destruct+0x24/0x1f0 sk_psock_destroy+0x19b/0x1c0 process_one_work+0x1b3/0x3c0 worker_thread+0x30/0x350 ? process_one_work+0x3c0/0x3c0 kthread+0xe6/0x110 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x22/0x30 </TASK>
