been resolved:\n\ntcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets\n\nTCP_SYN_RECV state is really special, it is only used by\ncross-syn connections, mostly used by fuzzers.\n\nIn the following crash [1], syzbot managed to trigger a divide\nby zero in tcp_rcv_space_adjust()\n\nA socket makes the following state transitions,\nwithout ever calling tcp_init_transfer(),\nmeaning tcp_init_buffer_space() is also not called.\n\n TCP_CLOSE\nconnect()\n TCP_SYN_SENT\n TCP_SYN_RECV\nshutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN)\n TCP_FIN_WAIT1\n\nTo fix this issue, change tcp_shutdown() to not\nperform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,\nwhich makes no sense anyway.\n\nWhen tcp_rcv_state_process() later changes socket state\nfrom TCP_SYN_RECV to TCP_ESTABLISH, then look at\nsk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,\nand send a FIN packet from a sane socket state.\n\nThis means tcp_send_fin() can now be called from BH\ncontext, and must use GFP_ATOMIC allocations.\n\n[1]\ndivide error: 0000 [#1] PREEMPT SMP KASAN NOPTI\nCPU: 1 PID: 5084 Comm: syz-executor358 Not tainted 6.9.0-rc6-syzkaller-00022-g98369dccd2f8 #0\nHardware name: Google

been resolved:\n\ntcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets\n\nTCP_SYN_RECV state is really special, it is only used by\ncross-syn connections, mostly used by fuzzers.\n\nIn the following crash [1], syzbot managed to trigger a divide\nby zero in tcp_rcv_space_adjust()\n\nA socket makes the following state transitions,\nwithout ever calling tcp_init_transfer(),\nmeaning tcp_init_buffer_space() is also not called.\n\n TCP_CLOSE\nconnect()\n TCP_SYN_SENT\n TCP_SYN_RECV\nshutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN)\n TCP_FIN_WAIT1\n\nTo fix this issue, change tcp_shutdown() to not\nperform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,\nwhich makes no sense anyway.\n\nWhen tcp_rcv_state_process() later changes socket state\nfrom TCP_SYN_RECV to TCP_ESTABLISH, then look at\nsk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,\nand send a FIN packet from a sane socket state.\n\nThis means tcp_send_fin() can now be called from BH\ncontext, and must use GFP_ATOMIC allocations.\n\n[1]\ndivide error: 0000 [#1] PREEMPT SMP KASAN NOPTI\nCPU: 1 PID: 5084 Comm: syz-executor358 Not tainted 6.9.0-rc6-syzkaller-00022-g98369dccd2f8 #0\nHardware name: Google

shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets\nTCP_SYN_RECV state is really special, it is only used by\ncross-syn connections, mostly used by fuzzers.\nIn the following crash [1], syzbot managed to trigger a divide\nby zero in tcp_rcv_space_adjust()\nA socket makes the following state transitions,\nwithout ever calling tcp_init_transfer(),\nmeaning tcp_init_buffer_space() is also not called.\nTCP_CLOSE\nconnect()\nTCP_SYN_SENT\nTCP_SYN_RECV\nshutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN)\nTCP_FIN_WAIT1\nTo fix this issue, change tcp_shutdown() to not\nperform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,\nwhich makes no sense anyway.\nWhen tcp_rcv_state_process() later changes socket state\nfrom TCP_SYN_RECV to TCP_ESTABLISH, then look at\nsk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,\nand send a FIN packet from a sane socket state.\nThis means tcp_send_fin() can now be called from BH\ncontext, and must use GFP_ATOMIC allocations.\n[1]\ndivide error: 0000 [#1]
